2) 情態(tài)動(dòng)詞should“應(yīng)該”學(xué)會(huì)使用

3) What...? 與 Which...?
1. what 與 which 都是疑問代詞,都可以指人或事物。但是what僅用來詢問職業(yè)。如:

該句相當(dāng)于: What does your father do?
What is your father's job?

Which is Peter? 哪個(gè)是皮特?
---The boy behind Mary. 瑪麗背后的那個(gè)男孩。

7) forget doing/to do與remember doing/to do
1.forget to do 忘記要去做某事。 (未做)
forget doing 忘記做過某事。 (已做)
The light in the office is still on. He forgot to turn it off.
辦公室的燈還在亮著,它忘記關(guān)了。(沒有做關(guān)燈的動(dòng)作)
He forgot turning the light off. 他忘記他已經(jīng)關(guān)了燈了。( 已做過關(guān)燈的動(dòng)作)
Don't forget to come tomorrow.
別忘了明天來。
(to come動(dòng)作未做)
典型例題
---- The light in the office is still on.
---- Oh,I forgot___.
A. turning it off B. turn it off
C. to turn it off D. having turned it off
答案:C。
由the light is still on 可知燈亮著,即關(guān)燈的動(dòng)作沒有發(fā)生,因此用forget to do sth.而forget doing sth 表示燈已經(jīng)關(guān)上了,而自己忘記了這一事實(shí)。此處不符合題意。
2.remember to do 記得去做某事 (未做)
remember doing 記得做過某事 (已做)
Remember to go to the post office after school. 記著放學(xué)后去趟郵局。
Don't you remember seeing the man before?
你不記得以前見過那個(gè)人嗎?
