參考范文：

Good morning, boys and girls!

The topic of my speech today is “Learn to express thanks”. We find some students want to eat well and wear fashionable clothes at school. When they leave school and enter society, they don’t know how to show any sense of thanks.

I think this behavior is not correct. As students, we should learn to express thanks. The society offers us a chance to receive good education. And our parents also support us to go to school. Our teachers teach us much knowledge, so we should thank them. We should also thank our friends because they can always give us courage and help.

In the future, we should never forget our society, parents, teachers and friends. At present, we should study harder to make our world more beautiful. Thank you for your listening!

【拓展】as soon as 引導(dǎo)的時(shí)間狀語(yǔ)從句前后時(shí)態(tài)搭配：

(1) 主句為一般將來(lái)時(shí)，從句用一般現(xiàn)在時(shí)表示將來(lái)。例如：

他一到北京就來(lái)我家。

(2) 主句為一般過(guò)去時(shí)，從句也用一般過(guò)去時(shí)。例如：

2. Finally, a god was so moved by Yu Gong that he sent two gods to take the mountains away.

so…that…引導(dǎo)結(jié)果狀語(yǔ)從句，意為“如此……以至于……”，此句型中，so是副詞，常用來(lái)修飾形容詞或副詞。常用句型為：主語(yǔ)+謂語(yǔ)+ so+ adj./adv. + that從句。例如：

我們的老師是如此好心以至于我們都喜歡他。

他跑得那么快，我們班沒(méi)有人能追上他。

【拓展】“如此……以至于……”歸納：

(1) so + 形容詞 + a/an + 單數(shù)名詞 + that從句 = such + a/an + 形容詞 + 單數(shù)名詞+ that從句。例如：

It was so fine a day yesterday that we all went out for a picnic. = It was such a fine day yesterday that we all went out for a picnic.

3. It doesn’t seem very possible to move a mountain.

seem此處作連系動(dòng)詞，意為“似乎;好像”，后跟形容詞作表語(yǔ)?？梢院蛃eem to be相互轉(zhuǎn)換。例如：

He seems very angry. = He seems to be very angry.

他好像非常生氣。

【拓展】

(1) “主語(yǔ) + seem + (to be) +表語(yǔ)”，表語(yǔ)多為名詞或形容詞，以說(shuō)明主語(yǔ)的特征或狀態(tài)。例如：

Tom seems (to be) a very clever boy. Tom

看上去是一個(gè)非常聰明的男孩。

Mr. Black seemed to be quite happy.

Black先生好像十分快樂(lè)。

(2) “主語(yǔ) + seem + 不定式”，此句型中，seem與不定式一起構(gòu)成復(fù)合謂語(yǔ)。例如：

格林夫人似乎不太喜歡這個(gè)主意。

似乎沒(méi)有人知道在公園里發(fā)生了什么事。

It seems to me that Mr. Brown will not come again.

在我看來(lái)布朗先生不會(huì)再來(lái)了。

(4) “There + seem to be + 名詞”，to be可省略，seem的單復(fù)數(shù)要由后面的名詞決定。例如：

There doesn’t seem to be much hope of our beating that team.

看來(lái)我們戰(zhàn)勝那個(gè)隊(duì)沒(méi)有多大希望。

There seems no need to wait longer. 看來(lái)沒(méi)有再等的必要了。

4. ...what’s possible unless you try to make it happen.

unless是連詞，引導(dǎo)條件狀語(yǔ)從句，意為“除非……;如果不……;除了……”，常引導(dǎo)一個(gè)否定意義的真實(shí)條件句，有時(shí)也可引導(dǎo)非真實(shí)條件句。unless引導(dǎo)的條件狀語(yǔ)從句中的謂語(yǔ)動(dòng)詞常用一般現(xiàn)在時(shí)代替一般將來(lái)時(shí)。主要用于下列情況：

(1) 主句為肯定句：

你要不快點(diǎn)就會(huì)錯(cuò)過(guò)班車(chē)。
