比較級的用法
①雙方比較，表示一方超過另一方時，用“比較級+than”的結(jié)構(gòu)表示。
例如：This pen is better than that one.
?、诒硎疽环讲患傲硪环綍r，用“l(fā)ess+原級+than”的結(jié)構(gòu)表示。例如：
This room is less beautiful than that one.
③表示一方超過另一方的程度或數(shù)量時，可在比較級前加表示程度的狀語，如：even，a lot，a bit，a little，still，much，far, yet, by far等修飾。例如：He works even harder than before.
注意:英語的比較級前如無even, still,或yet 等時,譯成漢語時可用“較”或“……一些”或不譯出,一般不可用“更”,如:
She is better than she was yesterday.她比昨天好些了。
Please come earlier tomorrow.請明天早點(diǎn)來。
注意:by far 通常用于強(qiáng)調(diào)最高級。用于比較級時,一般放在比較級的后面, 如放在前面,應(yīng)在二者中間加“the”。
如:He is taller by far than his brother. He is by far the taller of the two brothers.
?、鼙硎疽环诫S另一方的程度而變化時，用“the+比較級(主語+謂語),the+比較級(主語+謂語)”的結(jié)構(gòu)。例如：
The harder he works，the happier he feels.
⑤不與其它事物相比，表示本身程度的改變時，用“比較級+and+比較級”的結(jié)構(gòu)。例如：The weather is getting colder and colder.
The girl becomes more and more beautiful.
⑥某些以-or結(jié)尾的形容詞進(jìn)行比較時，用to代替than。(這些詞有inferior，superior6，junior，senior，prior等。例如：
He is superior to Mr Wang in mathematics.
?、咴诒容^從句中為了避免重復(fù)，我們通常用that(those)，one(ones)代替前面出現(xiàn)的名詞。that指物，one既可指人，也可指物。that可代替可數(shù)名詞單數(shù)和不可數(shù)名詞，而one只能代替可數(shù)名詞。例如：
The book on the table is more interesting than that on the desk.
A box made of iron is stronger than one made of wood.
⑧表示倍數(shù)的比較級有如下幾種句型:
A) A is three (four,etc.) times the size (height, length, width,etc) of B.
例如:The new building is four times the size (the height) of the old one.
這座新樓是那座舊樓的四倍大(四倍高)。
(這座新樓比那座舊樓大三倍[高三倍])。
B) A is three (four, etc.) times as big (high, long, wide, etc.) as B.例如:
Asia is four times as large as Europe.亞洲是歐洲的四倍大。
(亞洲比歐洲大三倍。)
C) A is three (four,etc.) times bigger (higher, longer, wider,etc.) than B.
例如:Your school is three times bigger than ours.
你們的學(xué)校比我們的學(xué)校大三倍。(你們的學(xué)校是我們學(xué)校的四倍大。)
用 times 表示倍數(shù), 一般只限于表示包括基數(shù)在內(nèi)三倍或三倍以上的數(shù)。表示兩倍可以用 twice 或 double
3)最高級的用法
?、偃呋蛉咭陨舷啾?，表示最高程度時，用“the+最高級”的結(jié)構(gòu)表示。這種句式一般常有表示比較范圍的介詞短語。例如：
Zhang Hua is the tallest of the three.He works (the) hardest in his class.
?、谧罡呒壙杀恍驍?shù)詞以及much, by far, nearly, almost, by no means, not quite, not really,nothing like等詞語所修飾。例如:
This hat is by far/ much/ nearly/ almost / not nearly/by no means/ not quite/nothing like the biggest.
How much did the second most expensive hat coat?
③表示“最高程度”的形容詞，如excellent，extreme，perfect等，沒有最高級，也不能用比較級。
④形容詞最高級修飾作表語或介詞賓語的名詞、代詞時，被修飾的詞往往省略。He is the tallest (boy) in his class.
⑤作狀語的副詞最高級前可以不加定冠詞。例如：
Of all the boys he came (the) earliest.
如果復(fù)數(shù)名詞前有many、few，不可數(shù)名詞前有much、little等表示量的形容詞時，該用so而不用such。如：
I've had so many falls that I'm black and blue all over.
Mr White got so little money a month that he could hardly keep body and soul together.
但little不表示數(shù)量而表示“小”的意思時,仍用such。如:
They are such little children that the they cannot clean the house by themslves.
6)almost與nearly
?、賰烧叨伎梢孕揎?all, every, always等詞，都可以用于否定句中。
?、谠趘ery, pretty, not后用nearly, 不用almost。例如：
I'm not nearly ready.
?、墼赼ny, no, none, never前用almost, 不用nearly。例如：
I almost never see her.
need 表示“需要”或“必須”,作情態(tài)動詞時,僅用于否定句或疑問句中。在肯定句中一般用must, have to, ought to或should 代替。例如：
You needn't come so early. Need I finish the work today? --Yes, you must.
注意：needn't+不定式的完成式“表示本來不必做某事而實(shí)際上做了某事”。例如：You needn't have waited for me.
“should+have+過去分詞”表示應(yīng)該做到而實(shí)際上沒有做到。
You should have started earlier.
“ought to + have + 過去分詞”表示過去應(yīng)做某事而實(shí)際未做。
You ought to have helped him (but you didn't)
書報(bào)的標(biāo)題,小說等情節(jié)介紹常用一般現(xiàn)在時。
表示感覺,愿望和狀態(tài)的某些動詞如have,be,hear,see,like等詞一般不用進(jìn)行時。
有些動詞形式上是主動結(jié)構(gòu),但表示被動的意思。常見的有可和 well, easily 等副詞連用的不及物動詞sell,wash,write,read,clean,cook等。例如：
The cloth washes well.這布很經(jīng)洗。
The new product sells well.這新產(chǎn)品很暢銷。
The pen writes well.這支筆很好寫。
虛擬語氣在動詞 arrange,command, demand, desire,insist, order,propose, request, require, suggest等后面的賓語從句中用“(should)+ 動詞原形”。
例如：We suggested that we (should) have a meeting.
We insisted that they (should) go with us.
The doctor ordered that she (should) stay in bed for a few days.
He demanded that we (should) start right away.
注意:insist 作“力言”、“強(qiáng)調(diào)”解時,賓語從句不用虛擬語氣。只有當(dāng) insist 作“堅(jiān)持(認(rèn)為),”“堅(jiān)持(應(yīng)該)”解時賓語從句才用虛擬語氣。例如:
Mike insisted that he had never stolen anything.
作advice,idea,order,demand,plan,proposal,suggestion,request等名詞的表語從句和同位語從句,其謂語動詞要用虛擬語氣的結(jié)構(gòu)“(should)+動詞原形”。例如：We all agreed to his suggestion that we(should) go to Beijing for sightseeing.
My idea is that we (should) do exercises first.
在feel,hear,listen to,look at,notice,observe,see, watch,have,let,make等詞后的補(bǔ)足語中,不定式不帶to。但是這些句子如果變成被動結(jié)構(gòu)時,就必須帶to。例如：I often hear him sing the song. He is often heard to sing the song.
注意：不定式動詞在介詞but, except, besides后面時,如果這些介詞之前有行為動詞do的各種形式,那么,這些介詞后的不定式不帶to,否則要帶to.如：
She could do nothing but cry. What do you like to do besides swim?
I have no choice but to go.
作定語的不定式如果是不及物動詞,或者不定式所修飾的名詞或代詞是不定式動作的地點(diǎn)、工具等,不定式后面須有相應(yīng)的介詞。例如：
He is looking for a room to live in. There is nothing to worry about.
Please give me a knife to cut with.
在 It is no use/good,not any use/good,useless,There is no 等后必須用動名詞。
2)作表語。例如：Her job is teaching7.
3)作賓語。例如：He is fond of playing football. I like swimming.
注① admit,appreciate,avoid,consider,delay,dislike,enjoy,escape,excuse,face,feel like,finish,forgive,give up,imagine,include, keep,mention,mind,miss,practise,put off,resist,risk,suggest, can't help, can't stand(無法忍受)等動詞后可以用動名詞作賓語,但不能用不定式。
注②forget, go on,like,mean,regret, remember, stop, try等動詞可帶動名詞或不定式作賓語,但意義上有區(qū)別。
I remember doing the exercise .(我記得做過練習(xí)。)
I must remember to do it .(我必須記著做這事。)
I tried not to go there.(我設(shè)法不去那里。)
I tried doing it again.(我試著又干了一次。)]
Stop speaking .(不要講話。)He stopped to talk .(他停下來講話。)
mean to do 有意... mean doing意味著...
I mean to come early today.(我打算今天早些來。)
Missing the train means waiting for another hour.
(誤了這趟火車意味著再等一個小時。)
注③在allow, advise, forbid, permit 等動詞后直接跟動詞作賓語時,要用動名詞形式,如果后面有名詞或代詞作賓語,然后再跟動詞作賓語補(bǔ)足語時,其賓語補(bǔ)足語用帶to的不定式。例如：
We don't allow smoking here. We don't allow students to smoke.
注④動詞need,require,want作“需要”解,其后跟動詞作它的賓語時,若表示的含義是被動的,必須用動名詞,或不定式的被動式。例如：
The window needs(requires, wants)cleaning(to be cleaned).
注⑤在短語devote to, look forward to, pay attention to, stick to,to be used to, object to,thank you for, excuse me for 等后的動詞也必須用動名詞形式。例如：I look forward to hearing from you soon.
過去分詞、現(xiàn)在分詞一般被動式及完成被動式作狀語的比較：
1)過去分詞與現(xiàn)在分詞一般被動式都有被動意義，有時兩者無多大區(qū)別。
例如:(Being) seized with a sudden fear, she gave a scream.
在某些情況下，二者則是有區(qū)別的。例如：
United, we stand; divided, we fall.(條件)
Badly polluted, the water cannot be drunk8.(原因)
Being written in haste9, the composition is full of mistakes.
(原因,強(qiáng)調(diào)寫的過程,故應(yīng)用現(xiàn)在分詞一般被動式)
2)有時過去分詞與現(xiàn)在分詞完成被動式皆表示已完成的動作，在意義上無多大區(qū)別。例如：
(Having been) weakened10 by storms, the bridge was no longer safe.
但有時是有區(qū)別的。例如：
Having been deserted11 by his guide, he couldn't find his way through the jungle.(為了強(qiáng)調(diào)已完成的動作)
Asked to stay, I couldn't very well refuse.
(這里 asked 可能意味著 having been asked, 也可能意味著when/since I was asked, 但用了 having been asked 就不會有歧義。)
下面句中過去分詞表示的時間與謂語動詞所表示的時間相同，所以不能代之以強(qiáng)調(diào)先于謂語動詞的現(xiàn)在分詞完成被動式。例如：
Covered with confusion12, I left the room.我很窘地離開了房間。
United, we stand; divided, we fall. 團(tuán)結(jié)則存，分裂則亡。
3)有時現(xiàn)在分詞一般式的被動式與其完成式的被動式完全同義，皆表示已完成的動作。這時用一般式的被動式較好。例如：Being surrounded (Having been surrounded)the enemy troups were forced to surrender13.
前句的謂語是there be,后邊的疑問部分也用there be形式。例如：
There is a radio on the table,isn't there? Yes,there is.
前句的謂語動詞為 have to /had to 時,其疑問部分的謂語動詞通常用do 的適當(dāng)形式。例如:We have to get up at four tomorrow, don't we?
They had to leave early, didn't they?
前句的謂語動詞為used to 時,其疑問部分的謂語動詞可采取兩種形式。
例如:He used to live in London, use(d)n't he /didn't he?
There used to be a cinema here before the war, use(d)n't there /didn't there?
前句的謂語動詞是ought to, 則疑問部分的謂語動詞通常用ought /oughtn't 代替。例如:Such things ought not to be allowed, ought they?
He ought to be punished, oughtn't he?
但在正式文體中,用ought we not形式。例如:
We ought to go, ought we not?或We ought to go ,should we not?
當(dāng)陳述部分有dare 或need 時,若dare 和need為實(shí)義動詞,疑問部分的謂語用do 的適當(dāng)形式;若dare 和need 為情態(tài)動詞,疑問部分用dare 或need 構(gòu)成。例如:We need to do it, don't we? You daren't go there, dare you?
含有情態(tài)動詞must的句子表示推則,作“想必”解時,疑問部分要根據(jù)must后面的不定式結(jié)構(gòu)的時態(tài)來確定,不可用mustn't。若前句強(qiáng)調(diào)對現(xiàn)在情況的推測,疑問部分用aren't(isn't)十主語,例如：You must be tired,aren't you?
注意:若陳述部分的must表示“有必要”時,附加疑問句部分則用needn't。
例如：You must go home right now, needn't you?
當(dāng)mustn't 表示禁止時,附加疑問部分一般用must。如：
You mustn't walk on grass, must you?
前句謂語動詞是must have+過去分詞時,若前句強(qiáng)調(diào)對過去情況的推測(一般有過去時間狀語),疑問部分的謂語動詞用didn't+主語;若前句強(qiáng)調(diào)動作的完成,疑問部分的謂語動詞用haven't(hasn't)+主語, 例如：
He must have met her yesterday, didn't he?
You must have seen the film, haven't you?
陳述句謂語部分出現(xiàn)否定詞綴時(前綴或后綴),疑問部分仍用否定結(jié)構(gòu)。例如:He is unfit for his office, isn't he?
如果陳述部分包含有no,never,hardly,seldom,few,little,nowhere,nothing等否定或半否定詞時,疑問部分用肯定形式。例如：He is hardly 14 years old,is he?
如果陳述部分的主語為everyone,someone,no one等不定代詞,其疑問部分的主語可用he,也可用they,從而疑問部分的謂語動詞也可用復(fù)數(shù)形式。例如：
Everyone knows his job, doesn't he? Everyone knows their job,don't they?
No one was hurt,were they?
如果陳述部分的主語是指示代詞this,that等時,疑問部分的主語在形式上與前者不同,但在邏輯上卻與前者一致。例如：This is very important,isn't it?
如果陳述部分是 I'm...結(jié)構(gòu),附加疑問部分一般用 aren't I。
例如：I'm late, aren't I?
如果陳述部分以不定式代詞one作主語,附加疑問部分的主語在正式的場合用one,在非正式的場合用you。例如：One can't be too careful,can one(you)?
Have a cup of tea, will you? Let's go there,shall we?
但：Let us go there,will you?
同位語從句跟在名詞后面,進(jìn)一步說明該名詞的具體內(nèi)容。引導(dǎo)同位語從句的名詞主要有fact,news,promise,idea,truth等。連接詞用that (不用which),及連接副詞how, when, where, why等。例如：
His delay is due to the fact that the car went wrong halfway14.
The news that our team has won the match is true.
She asked the reason why there was a delay.
關(guān)聯(lián)詞只能用whether不能用if表示“是否”的情況如下:
A)在表語從句和同位語從句中。例如：
The question is whether the film is worth seeing.
The news whether our team has won the match is unknown.
B)在主語從句中,只有用it作形式主語時,whether和if都能引導(dǎo)主語從句,否則,也只能用whether。例如：
Whether we shall attend the meeting hasn't been decided15 yet.
It hasn't been decided whether(if)we shall attend the meeting.
C)在介詞之后。(介詞往往可以省略)例如：
It all depends (on) whether) they will support us.
D)后面直接跟動詞不定式時。例如：He doesn't know whether to stay or not.
E)后面緊接or not 時。例如：We didn't know whether or not she was ready.
F)引導(dǎo)讓步狀語從句,只能用whether。例如：
Whether you like it or not, you must do it well.
G)用if會引起歧義時。例如：Please let me know if you like it.
該句有兩個意思：“請告訴我你是否喜歡”。
或“如果你喜歡,請告訴我?！庇昧藈hether就可以避免。
?、陉P(guān)聯(lián)詞if,whether均可使用的情況如下：
A)引導(dǎo)賓語從句。例如：I wonder if(whether) the news is true or not.
B)在“be+形容詞”之后。 例如：He was not sure whether(if) it is right or wrong.
?、坳P(guān)聯(lián)詞只能用whether或if,不能用that的情況如下：若doubt一詞作“懷疑”解接賓語從句時,主句為肯定句用whether或if,主句為否定句或疑問句用that。例如：I doubt whether he will come soon.
I do not doubt that he will come soon. Do you doubt that he will come soon?
在下面幾種情況下必須用“that”引導(dǎo)定語從句：
1)先行詞是不定代詞：all,few,little, much,something,nothing,anything等。
例如：All that we have to do is to practise every day.
2)先行詞被序數(shù)詞或形容詞最高級所修飾。例如：
The first lesson that I learned16 will never be forgotten.
3)先行詞被all,any,every, each, few,little,no,some, 等修飾。例如：
I have read all the book [ZZ(Z](that)[ZZ)] you gave me.
4)先行詞被 the only, the very, the same, the last 修飾時。例如:
He is the only person that I want to talk to.
5)先行詞既有人又有物時。例如：
They talked of things and persons that they remembered in the school.
4.由when,where,why引導(dǎo)的定語從句。例如：
I know the reason why he came late.
This is the place where we lived for 5 years.
I will never forget the day when I met Mr.Liu.
注意：先行詞是表示地點(diǎn)時,有時用where,有時用that (which)引導(dǎo)定語從句。這時要根據(jù)從句的謂語動詞是及物的還是不及物的。如果是及物的就用that(which),否則用where。例如：This is the house where he lived last year.
This is the house that (which) he visited last year.
用no sooner…than和hardly…when引導(dǎo)的從句表示“剛……就……”。主句中的動詞一般用過去完成時,從句用過去時;而且主句一般倒裝,把助動詞had提到前面。例如：Hardly had I entered the room when I heard a loud noise.
當(dāng)我們要表示“某件事已成”時,應(yīng)用“was (were) able to”,而不能用“could”。例如：He was able to go to the party yesterday evening and he enjoyed himself very much.
倒 裝
英語句子的自然語序是主語在前,謂語動詞在后。把謂語動詞放在主語之前,就叫倒裝結(jié)構(gòu)。如果全部謂語放在主語之前,叫全部例裝;如果只把助動詞或情態(tài)動詞放在主語之前就叫部分倒裝。倒裝結(jié)構(gòu)通常用于下列場合。

2)Inside the pyramids are the burial rooms for the kings and queens and long passages to these rooms.
(二)部分倒裝
1.用于疑問句。例如：Do you speak English?
2.用于省略if的虛擬條件狀語從句。例如：
Had you reviewed your lessons,you might have passed the examination17.
3.用于“形容詞(或名詞、動詞)+as(though)引導(dǎo)的讓步狀語從句中。例如：Pretty as she is ,she is not clever. Try as he would, he might fail again.
注意：1)在用as(though)引導(dǎo)的讓步狀語從句中,如果主語較長,也可實(shí)行全部倒裝。例如：Difficult as was the chemistry homework, it was finished in time.
2)如果從句的表語是名詞,其名詞前不加任何冠詞。例如：
Child as he was, he had to make a living.

The teacher as well as the students was excited.
The room with its furniture was rented.
關(guān)系代詞who, that, which等在定語從句中作主語時, 其謂語動詞的數(shù)應(yīng)與句中先行詞的數(shù)一致。例如:
Those who want to go please sign your names here.
Some of the energy that is used by man comes from the sun.
19)疑問代詞who, what, which 作主語時, 謂語動詞可根據(jù)說話人所要表達(dá)的意思決定單復(fù)數(shù)。例如:

比較級的用法
?、匐p方比較，表示一方超過另一方時，用“比較級+than”的結(jié)構(gòu)表示。
例如：This pen is better than that one.
②表示一方不及另一方時，用“l(fā)ess+原級+than”的結(jié)構(gòu)表示。例如：
This room is less beautiful than that one.
?、郾硎疽环匠^另一方的程度或數(shù)量時，可在比較級前加表示程度的狀語，如：even，a lot，a bit，a little，still，much，far, yet, by far等修飾。例如：He works even harder than before.
注意:英語的比較級前如無even, still,或yet 等時,譯成漢語時可用“較”或“……一些”或不譯出,一般不可用“更”,如:
She is better than she was yesterday.她比昨天好些了。
Please come earlier tomorrow.請明天早點(diǎn)來。
注意:by far 通常用于強(qiáng)調(diào)最高級。用于比較級時,一般放在比較級的后面, 如放在前面,應(yīng)在二者中間加“the”。
如:He is taller by far than his brother. He is by far the taller of the two brothers.
?、鼙硎疽环诫S另一方的程度而變化時，用“the+比較級(主語+謂語),the+比較級(主語+謂語)”的結(jié)構(gòu)。例如：
The harder he works，the happier he feels.
?、莶慌c其它事物相比，表示本身程度的改變時，用“比較級+and+比較級”的結(jié)構(gòu)。例如：The weather is getting colder and colder.
The girl becomes more and more beautiful.
?、弈承┮?or結(jié)尾的形容詞進(jìn)行比較時，用to代替than。(這些詞有inferior，superior，junior，senior，prior等。例如：
He is superior to Mr Wang in mathematics.
⑦在比較從句中為了避免重復(fù)，我們通常用that(those)，one(ones)代替前面出現(xiàn)的名詞。that指物，one既可指人，也可指物。that可代替可數(shù)名詞單數(shù)和不可數(shù)名詞，而one只能代替可數(shù)名詞。例如：
The book on the table is more interesting than that on the desk.
A box made of iron is stronger than one made of wood.
?、啾硎颈稊?shù)的比較級有如下幾種句型:
A) A is three (four,etc.) times the size (height, length, width,etc) of B.
例如:The new building is four times the size (the height) of the old one.
這座新樓是那座舊樓的四倍大(四倍高)。
(這座新樓比那座舊樓大三倍[高三倍])。
B) A is three (four, etc.) times as big (high, long, wide, etc.) as B.例如:
Asia is four times as large as Europe.亞洲是歐洲的四倍大。
(亞洲比歐洲大三倍。)
C) A is three (four,etc.) times bigger (higher, longer, wider,etc.) than B.
例如:Your school is three times bigger than ours.
你們的學(xué)校比我們的學(xué)校大三倍。(你們的學(xué)校是我們學(xué)校的四倍大。)
用 times 表示倍數(shù), 一般只限于表示包括基數(shù)在內(nèi)三倍或三倍以上的數(shù)。表示兩倍可以用 twice 或 double
3)最高級的用法
?、偃呋蛉咭陨舷啾?，表示最高程度時，用“the+最高級”的結(jié)構(gòu)表示。這種句式一般常有表示比較范圍的介詞短語。例如：
Zhang Hua is the tallest of the three.He works (the) hardest in his class.
?、谧罡呒壙杀恍驍?shù)詞以及much, by far, nearly, almost, by no means, not quite, not really,nothing like等詞語所修飾。例如:
This hat is by far/ much/ nearly/ almost / not nearly/by no means/ not quite/nothing like the biggest.
How much did the second most expensive hat coat?
?、郾硎尽白罡叱潭取钡男稳菰~，如excellent，extreme，perfect等，沒有最高級，也不能用比較級。
?、苄稳菰~最高級修飾作表語或介詞賓語的名詞、代詞時，被修飾的詞往往省略。He is the tallest (boy) in his class.
⑤作狀語的副詞最高級前可以不加定冠詞。例如：
Of all the boys he came (the) earliest.
如果復(fù)數(shù)名詞前有many、few，不可數(shù)名詞前有much、little等表示量的形容詞時，該用so而不用such。如：
I've had so many falls that I'm black and blue all over.
Mr White got so little money a month that he could hardly keep body and soul together.
但little不表示數(shù)量而表示“小”的意思時,仍用such。如:
They are such little children that the they cannot clean the house by themslves.
6)almost與nearly
①兩者都可以修飾 all, every, always等詞，都可以用于否定句中。
?、谠趘ery, pretty, not后用nearly, 不用almost。例如：
I'm not nearly ready.
③在any, no, none, never前用almost, 不用nearly。例如：
I almost never see her.
need 表示“需要”或“必須”,作情態(tài)動詞時,僅用于否定句或疑問句中。在肯定句中一般用must, have to, ought to或should 代替。例如：
You needn't come so early. Need I finish the work today? --Yes, you must.
注意：needn't+不定式的完成式“表示本來不必做某事而實(shí)際上做了某事”。例如：You needn't have waited for me.
“should+have+過去分詞”表示應(yīng)該做到而實(shí)際上沒有做到。
You should have started earlier.
“ought to + have + 過去分詞”表示過去應(yīng)做某事而實(shí)際未做。
You ought to have helped him (but you didn't)
書報(bào)的標(biāo)題,小說等情節(jié)介紹常用一般現(xiàn)在時。
表示感覺,愿望和狀態(tài)的某些動詞如have,be,hear,see,like等詞一般不用進(jìn)行時。
有些動詞形式上是主動結(jié)構(gòu),但表示被動的意思。常見的有可和 well, easily 等副詞連用的不及物動詞sell,wash,write,read,clean,cook等。例如：
The cloth washes well.這布很經(jīng)洗。
The new product sells well.這新產(chǎn)品很暢銷。
The pen writes well.這支筆很好寫。
虛擬語氣在動詞 arrange,command, demand, desire,insist, order,propose, request, require, suggest等后面的賓語從句中用“(should)+ 動詞原形”。
例如：We suggested that we (should) have a meeting.
We insisted that they (should) go with us.
The doctor ordered that she (should) stay in bed for a few days.
He demanded that we (should) start right away.
注意:insist 作“力言”、“強(qiáng)調(diào)”解時,賓語從句不用虛擬語氣。只有當(dāng) insist 作“堅(jiān)持(認(rèn)為),”“堅(jiān)持(應(yīng)該)”解時賓語從句才用虛擬語氣。例如:
Mike insisted that he had never stolen anything.
作advice,idea,order,demand,plan,proposal,suggestion,request等名詞的表語從句和同位語從句,其謂語動詞要用虛擬語氣的結(jié)構(gòu)“(should)+動詞原形”。例如：We all agreed to his suggestion that we(should) go to Beijing for sightseeing.
My idea is that we (should) do exercises first.
在feel,hear,listen to,look at,notice,observe,see, watch,have,let,make等詞后的補(bǔ)足語中,不定式不帶to。但是這些句子如果變成被動結(jié)構(gòu)時,就必須帶to。例如：I often hear him sing the song. He is often heard to sing the song.
注意：不定式動詞在介詞but, except, besides后面時,如果這些介詞之前有行為動詞do的各種形式,那么,這些介詞后的不定式不帶to,否則要帶to.如：
She could do nothing but cry. What do you like to do besides swim?
I have no choice but to go.
作定語的不定式如果是不及物動詞,或者不定式所修飾的名詞或代詞是不定式動作的地點(diǎn)、工具等,不定式后面須有相應(yīng)的介詞。例如：
He is looking for a room to live in. There is nothing to worry about.
Please give me a knife to cut with.
在 It is no use/good,not any use/good,useless,There is no 等后必須用動名詞。
2)作表語。例如：Her job is teaching.
3)作賓語。例如：He is fond of playing football. I like swimming.
注① admit,appreciate,avoid,consider,delay,dislike,enjoy,escape,excuse,face,feel like,finish,forgive,give up,imagine,include, keep,mention,mind,miss,practise,put off,resist,risk,suggest, can't help, can't stand(無法忍受)等動詞后可以用動名詞作賓語,但不能用不定式。
注②forget, go on,like,mean,regret, remember, stop, try等動詞可帶動名詞或不定式作賓語,但意義上有區(qū)別。
I remember doing the exercise .(我記得做過練習(xí)。)
I must remember to do it .(我必須記著做這事。)
I tried not to go there.(我設(shè)法不去那里。)
I tried doing it again.(我試著又干了一次。)]
Stop speaking .(不要講話。)He stopped to talk .(他停下來講話。)
mean to do 有意... mean doing意味著...
I mean to come early today.(我打算今天早些來。)
Missing the train means waiting for another hour.
(誤了這趟火車意味著再等一個小時。)
注③在allow, advise, forbid, permit 等動詞后直接跟動詞作賓語時,要用動名詞形式,如果后面有名詞或代詞作賓語,然后再跟動詞作賓語補(bǔ)足語時,其賓語補(bǔ)足語用帶to的不定式。例如：
We don't allow smoking here. We don't allow students to smoke.
注④動詞need,require,want作“需要”解,其后跟動詞作它的賓語時,若表示的含義是被動的,必須用動名詞,或不定式的被動式。例如：
The window needs(requires, wants)cleaning(to be cleaned).
注⑤在短語devote to, look forward to, pay attention to, stick to,to be used to, object to,thank you for, excuse me for 等后的動詞也必須用動名詞形式。例如：I look forward to hearing from you soon.
過去分詞、現(xiàn)在分詞一般被動式及完成被動式作狀語的比較：
1)過去分詞與現(xiàn)在分詞一般被動式都有被動意義，有時兩者無多大區(qū)別。
例如:(Being) seized with a sudden fear, she gave a scream.
在某些情況下，二者則是有區(qū)別的。例如：
United, we stand; divided, we fall.(條件)
Badly polluted, the water cannot be drunk.(原因)
Being written in haste, the composition is full of mistakes.
(原因,強(qiáng)調(diào)寫的過程,故應(yīng)用現(xiàn)在分詞一般被動式)
2)有時過去分詞與現(xiàn)在分詞完成被動式皆表示已完成的動作，在意義上無多大區(qū)別。例如：
(Having been) weakened by storms, the bridge was no longer safe.
但有時是有區(qū)別的。例如：
Having been deserted by his guide, he couldn't find his way through the jungle.(為了強(qiáng)調(diào)已完成的動作)
Asked to stay, I couldn't very well refuse.
(這里 asked 可能意味著 having been asked, 也可能意味著when/since I was asked, 但用了 having been asked 就不會有歧義。)
下面句中過去分詞表示的時間與謂語動詞所表示的時間相同，所以不能代之以強(qiáng)調(diào)先于謂語動詞的現(xiàn)在分詞完成被動式。例如：
Covered with confusion, I left the room.我很窘地離開了房間。
United, we stand; divided, we fall. 團(tuán)結(jié)則存，分裂則亡。
3)有時現(xiàn)在分詞一般式的被動式與其完成式的被動式完全同義，皆表示已完成的動作。這時用一般式的被動式較好。例如：Being surrounded (Having been surrounded)the enemy troups were forced to surrender.
前句的謂語是there be,后邊的疑問部分也用there be形式。例如：
There is a radio on the table,isn't there? Yes,there is.
前句的謂語動詞為 have to /had to 時,其疑問部分的謂語動詞通常用do 的適當(dāng)形式。例如:We have to get up at four tomorrow, don't we?
They had to leave early, didn't they?
前句的謂語動詞為used to 時,其疑問部分的謂語動詞可采取兩種形式。
例如:He used to live in London, use(d)n't he /didn't he?
There used to be a cinema here before the war, use(d)n't there /didn't there?
前句的謂語動詞是ought to, 則疑問部分的謂語動詞通常用ought /oughtn't 代替。例如:Such things ought not to be allowed, ought they?
He ought to be punished, oughtn't he?
但在正式文體中,用ought we not形式。例如:
We ought to go, ought we not?或We ought to go ,should we not?
當(dāng)陳述部分有dare 或need 時,若dare 和need為實(shí)義動詞,疑問部分的謂語用do 的適當(dāng)形式;若dare 和need 為情態(tài)動詞,疑問部分用dare 或need 構(gòu)成。例如:We need to do it, don't we? You daren't go there, dare you?
含有情態(tài)動詞must的句子表示推則,作“想必”解時,疑問部分要根據(jù)must后面的不定式結(jié)構(gòu)的時態(tài)來確定,不可用mustn't。若前句強(qiáng)調(diào)對現(xiàn)在情況的推測,疑問部分用aren't(isn't)十主語,例如：You must be tired,aren't you?
注意:若陳述部分的must表示“有必要”時,附加疑問句部分則用needn't。
例如：You must go home right now, needn't you?
當(dāng)mustn't 表示禁止時,附加疑問部分一般用must。如：
You mustn't walk on grass, must you?
前句謂語動詞是must have+過去分詞時,若前句強(qiáng)調(diào)對過去情況的推測(一般有過去時間狀語),疑問部分的謂語動詞用didn't+主語;若前句強(qiáng)調(diào)動作的完成,疑問部分的謂語動詞用haven't(hasn't)+主語, 例如：
He must have met her yesterday, didn't he?
You must have seen the film, haven't you?
陳述句謂語部分出現(xiàn)否定詞綴時(前綴或后綴),疑問部分仍用否定結(jié)構(gòu)。例如:He is unfit for his office, isn't he?
如果陳述部分包含有no,never,hardly,seldom,few,little,nowhere,nothing等否定或半否定詞時,疑問部分用肯定形式。例如：He is hardly 14 years old,is he?
如果陳述部分的主語為everyone,someone,no one等不定代詞,其疑問部分的主語可用he,也可用they,從而疑問部分的謂語動詞也可用復(fù)數(shù)形式。例如：
Everyone knows his job, doesn't he? Everyone knows their job,don't they?
No one was hurt,were they?
如果陳述部分的主語是指示代詞this,that等時,疑問部分的主語在形式上與前者不同,但在邏輯上卻與前者一致。例如：This is very important,isn't it?
如果陳述部分是 I'm...結(jié)構(gòu),附加疑問部分一般用 aren't I。
例如：I'm late, aren't I?
如果陳述部分以不定式代詞one作主語,附加疑問部分的主語在正式的場合用one,在非正式的場合用you。例如：One can't be too careful,can one(you)?
Have a cup of tea, will you? Let's go there,shall we?
但：Let us go there,will you?
同位語從句跟在名詞后面,進(jìn)一步說明該名詞的具體內(nèi)容。引導(dǎo)同位語從句的名詞主要有fact,news,promise,idea,truth等。連接詞用that (不用which),及連接副詞how, when, where, why等。例如：
His delay is due to the fact that the car went wrong halfway.
The news that our team has won the match is true.
She asked the reason why there was a delay.
關(guān)聯(lián)詞只能用whether不能用if表示“是否”的情況如下:
A)在表語從句和同位語從句中。例如：
The question is whether the film is worth seeing.
The news whether our team has won the match is unknown.
B)在主語從句中,只有用it作形式主語時,whether和if都能引導(dǎo)主語從句,否則,也只能用whether。例如：
Whether we shall attend the meeting hasn't been decided yet.
It hasn't been decided whether(if)we shall attend the meeting.
C)在介詞之后。(介詞往往可以省略)例如：
It all depends (on) whether) they will support us.
D)后面直接跟動詞不定式時。例如：He doesn't know whether to stay or not.
E)后面緊接or not 時。例如：We didn't know whether or not she was ready.
F)引導(dǎo)讓步狀語從句,只能用whether。例如：
Whether you like it or not, you must do it well.
G)用if會引起歧義時。例如：Please let me know if you like it.
該句有兩個意思：“請告訴我你是否喜歡”。
或“如果你喜歡,請告訴我?！庇昧藈hether就可以避免。
?、陉P(guān)聯(lián)詞if,whether均可使用的情況如下：
A)引導(dǎo)賓語從句。例如：I wonder if(whether) the news is true or not.
B)在“be+形容詞”之后。 例如：He was not sure whether(if) it is right or wrong.
?、坳P(guān)聯(lián)詞只能用whether或if,不能用that的情況如下：若doubt一詞作“懷疑”解接賓語從句時,主句為肯定句用whether或if,主句為否定句或疑問句用that。例如：I doubt whether he will come soon.
I do not doubt that he will come soon. Do you doubt that he will come soon?
在下面幾種情況下必須用“that”引導(dǎo)定語從句：
1)先行詞是不定代詞：all,few,little, much,something,nothing,anything等。
例如：All that we have to do is to practise every day.
2)先行詞被序數(shù)詞或形容詞最高級所修飾。例如：
The first lesson that I learned will never be forgotten.
3)先行詞被all,any,every, each, few,little,no,some, 等修飾。例如：
I have read all the book [ZZ(Z](that)[ZZ)] you gave me.
4)先行詞被 the only, the very, the same, the last 修飾時。例如:
He is the only person that I want to talk to.
5)先行詞既有人又有物時。例如：
They talked of things and persons that they remembered in the school.
4.由when,where,why引導(dǎo)的定語從句。例如：
I know the reason why he came late.
This is the place where we lived for 5 years.
I will never forget the day when I met Mr.Liu.
注意：先行詞是表示地點(diǎn)時,有時用where,有時用that (which)引導(dǎo)定語從句。這時要根據(jù)從句的謂語動詞是及物的還是不及物的。如果是及物的就用that(which),否則用where。例如：This is the house where he lived last year.
This is the house that (which) he visited last year.
用no sooner…than和hardly…when引導(dǎo)的從句表示“剛……就……”。主句中的動詞一般用過去完成時,從句用過去時;而且主句一般倒裝,把助動詞had提到前面。例如：Hardly had I entered the room when I heard a loud noise.
當(dāng)我們要表示“某件事已成”時,應(yīng)用“was (were) able to”,而不能用“could”。例如：He was able to go to the party yesterday evening and he enjoyed himself very much.
倒 裝
英語句子的自然語序是主語在前,謂語動詞在后。把謂語動詞放在主語之前,就叫倒裝結(jié)構(gòu)。如果全部謂語放在主語之前,叫全部例裝;如果只把助動詞或情態(tài)動詞放在主語之前就叫部分倒裝。倒裝結(jié)構(gòu)通常用于下列場合。
(一)完全倒裝
1.用于there be句型。例如：There are many students in the classroom.
2.用于“here (there,now,then)+不及物動詞+主語”的句型中,或以out,in,up,down,away等副詞開頭的句子里,以表示強(qiáng)調(diào)。例如：
Here comes the bus. There goes the bell.
Now comes your turn. Out went the children.
注：代詞作主語時,主謂語序不變。例如：Here it is. Here he comes.
3.當(dāng)句首狀語為表示地點(diǎn)的介詞詞組時,也常常引起全部倒裝。例如:
South of the city lies a big steel factory.
From the valley came a frightening sound.
4.表語置于句首時,倒裝結(jié)構(gòu)為“表語+連系動詞+主語”。
1)形容詞+連系動詞+主語
Present at the meeting were Professor White,Professor Smith and many other guests.
2)過去分詞+連系動詞+主語
Gone are the days when they could do what they liked to the Chinese people.
3)介詞短語+be+主語
Among the goods are Christmas trees, flowers, candles and toys.
5.用于so,nor,neither開頭的句子,表示重復(fù)前句部分內(nèi)容。原句的謂語應(yīng)與前句謂語的時態(tài)、形式相一致。例如：He has been to Beijing. So have I.
Li Wei can't answer the question. Neither can I.
6.為了保持句子平衡,或?yàn)榱藦?qiáng)調(diào)表語或狀語,或使上下文緊密銜接時。
1)They arrived at a farmhouse,in front of which sat a small boy.
2)Inside the pyramids are the burial rooms for the kings and queens and long passages to these rooms.
(二)部分倒裝
1.用于疑問句。例如：Do you speak English?
2.用于省略if的虛擬條件狀語從句。例如：
Had you reviewed your lessons,you might have passed the examination.
3.用于“形容詞(或名詞、動詞)+as(though)引導(dǎo)的讓步狀語從句中。例如：Pretty as she is ,she is not clever. Try as he would, he might fail again.
注意：1)在用as(though)引導(dǎo)的讓步狀語從句中,如果主語較長,也可實(shí)行全部倒裝。例如：Difficult as was the chemistry homework, it was finished in time.
2)如果從句的表語是名詞,其名詞前不加任何冠詞。例如：
Child as he was, he had to make a living.
4.用于no sooner…than…,hardly…when和not until的句型中。例如：
Not until the teacher came did he finish his homework.
5.用于never,hardly,seldom,scarcely, barely, little,often,at no time,not only,not once等詞開頭的句子。例如：
Never shall I do this again. Little did he know who the woman was.
6.用于以only開頭的句子(only修飾副詞,介詞短語或狀語從句時)。例如：
Only this afternoon did I finish the novel.Only in this way can yo master English.
Only when he told me did I realize what trouble he was in.
如果only后面的詞組不是狀語,則不用倒裝。例如：
Only Wang Ling knows this.
7.如果直接引語后注明引語是什么人說的,而且主語是名詞時,用倒裝結(jié)構(gòu);主語是代詞時,一般不用倒裝。例如：“Let's go,” said the man.
8.用于某些表示祝愿的句子。例如：May you succeed!祝你成功!s in.
如果only后面的詞組不是狀語,則不用倒裝。例如：
Only Wang Ling knows this.
7.如果直接引語后注明引語是什么人說的,而且主語是名詞時,用倒裝結(jié)構(gòu);主語是代詞時,一般不用倒裝。例如：“Let's go,” said the man.
8.用于某些表示祝愿的句子。例如：May you succeed!祝你成功!
