七年級(jí)下冊(cè)英語(yǔ)知識(shí)點(diǎn)人教版2021
一. 情態(tài)動(dòng)詞can的用法
can+動(dòng)詞原形,它不隨主語(yǔ)的人稱和數(shù)而變化。
1. 含有can的肯定句:主語(yǔ)+can+謂語(yǔ)動(dòng)詞的原形+其他。
2. 含有can的否定句:主語(yǔ)+can't+動(dòng)詞的原形+其他。
3. 變一般疑問(wèn)句時(shí),把can提前:Can+主語(yǔ)+動(dòng)詞原形+其他? 肯定回答:Yes,主語(yǔ)+can。否定回答:No,主語(yǔ)+can't.
4. 含有can的特殊疑問(wèn)句:特殊疑問(wèn)詞+can+主語(yǔ)+動(dòng)詞原形+其他?
I can speak English.→I can't speak English.→Can you speak English? →What can you speak?
二. what time和when引導(dǎo)的特殊疑問(wèn)句
1. 詢問(wèn)鐘點(diǎn)時(shí)用what time,詢問(wèn)日期、月份、年份時(shí)用when。
2. What's the time?=What time is it?現(xiàn)在幾點(diǎn)了?
3. 時(shí)刻表達(dá)法:順讀法和逆讀法。
順讀法:“鐘點(diǎn)+分鐘”直接讀數(shù)字。
如:7: 05 seven five;8:16 eight sixteen
逆讀法:借助介詞past或to表示,要先說(shuō)分再說(shuō)鐘點(diǎn)。
a. 當(dāng)分鐘不超過(guò)30分鐘時(shí)(包括30分鐘),即<或=30,用past表示。其結(jié)構(gòu)為:“分鐘+past+整點(diǎn)” 意為“幾點(diǎn)過(guò)幾分”。
如:1:25 twenty-five past one
b. 當(dāng)超過(guò)30分鐘時(shí),即>30,用to表示。其結(jié)構(gòu)為:“所差分鐘(即60—所 過(guò)分鐘數(shù))+to+下一個(gè)整點(diǎn)”,to譯成“差”,差幾分鐘到幾點(diǎn)。
如:4:38 twenty-two to five
c. 當(dāng)分鐘為30分鐘用half表示,當(dāng)分鐘為15分鐘用a quarter。
三. how引導(dǎo)的特殊疑問(wèn)句

2. how far 用來(lái)提問(wèn)距離,多遠(yuǎn),其答語(yǔ)分為兩種:
(1)用長(zhǎng)度單位表示:It is five kilometers.
(2)用時(shí)間表示:It’s twenty minutes’walk.
3. how long 用來(lái)提問(wèn)時(shí)間,意為多久回答常用“for+段時(shí)”。

4. how soon 用來(lái)提問(wèn)做完某事還需要多長(zhǎng)時(shí)間, 用于將來(lái)時(shí)態(tài), 常用“in+時(shí)間段”來(lái)回答。
----How soon will you arrive in Beijing? ----In 3 hours.

語(yǔ)法:1,句中不含be(am,is,are)動(dòng)詞的 一般疑問(wèn)句的變法。 也就是說(shuō)句中謂語(yǔ)動(dòng)詞是實(shí)義動(dòng)詞時(shí),要變?yōu)橐话阋蓡?wèn)句,在句首加do/does(當(dāng)主語(yǔ)是第三人稱單數(shù)的時(shí)候用does),第一人稱變第二人稱,動(dòng)詞變?cè)纹渌恼Z(yǔ)序不變。I have a computer. – Do you have a computer?

2一般句子中當(dāng)主語(yǔ)是第三人稱單數(shù)的時(shí)候,謂語(yǔ)動(dòng)詞要起變化。具體的變化為:一般情況加s, know-knows,以s,x,ch,sh,o結(jié)尾的加es, teach-teaches, go-goes, 以輔音字母加y結(jié)尾,把y改為i, 再加es study-studies

但是如果做實(shí)義動(dòng)詞(能翻譯出來(lái)意思的動(dòng)詞)呢,遇到主語(yǔ)第三人稱單數(shù)就要起變化。
She does her homework.
4,have的第三人稱單數(shù)為 has.
