e.g. When did you read the novel?
She often came to help us in those days.
2 、談到過去的情況時(shí)
e.g. I didn`t know you were so busy.
3 、談到已死人的情況時(shí)

yesterday, last night, the other day, two months ago, in 1985, then, just now,
when, after, as soon as 引導(dǎo)的時(shí)間狀語從句，表示主句動(dòng)作開始的時(shí)間。
篇二：一般現(xiàn)在時(shí)
一般現(xiàn)在時(shí)主要用于：
1 、表示經(jīng)常性或習(xí)慣性動(dòng)作。
e.g. It seldom snows here.
2 、表示現(xiàn)在的特征或狀態(tài)。
e.g. He is always ready to help others.
3 、普遍真理。
e.g. Action speaks louder than words.
4 、劇情圖片介紹，背景說明，動(dòng)作解說。
e.g. (Tom enters the room_and_sits at the table)
Doctor ： What`s your trouble, young man?
Tom ： I`ve caught a cold, doctor.
5 、時(shí)間、條件、讓步、方式狀語從句表將要發(fā)生的動(dòng)作時(shí)。
e.g. Tomorrow we shall go for an outing unless it rains.
與這種時(shí)態(tài)連用的時(shí)間狀語常有：
always, often, never, seldom, usually, once, a week, now 等。
篇三：一般過去時(shí)現(xiàn)在完成時(shí)
一般過去時(shí)現(xiàn)在完成時(shí)主要用于：
1 、表示到現(xiàn)在為止這一時(shí)期中發(fā)生的動(dòng)作或情況，即多次動(dòng)作的總和。
e.g. We have learnt four English songs this month.
How many times have you read the novel?
For many days we haven`t seen each other.
2 、表示對(duì)現(xiàn)在有影響的某一已發(fā)生的動(dòng)作。
e.g. The delegation has left 代表團(tuán)已經(jīng)走了（說明現(xiàn)在不在這里）
Look, what you have done. 看你干的事。
與這一時(shí)態(tài)連用的時(shí)間狀語有：
already, yet, just, ever, never, by now, so far, recently, by the end of this month, since, for 短語，連詞 since 引導(dǎo)的時(shí)間狀語從句。
一般過去時(shí)與現(xiàn)在完成時(shí)的區(qū)別：
一般過去時(shí)：重在說明動(dòng)作在過去發(fā)生時(shí)的具體情況（時(shí)間、地點(diǎn)、方式、對(duì)象、細(xì)節(jié)等）。
現(xiàn)在完成時(shí)：只提起已發(fā)生的動(dòng)作（事實(shí)）及其影響，不說明動(dòng)作發(fā)生時(shí)的具體情況。
cf. Have you had your lunch?
What did you have for lunch?
I have ever been to the Great Wall,_and_I went there last summer with my father.
注：現(xiàn)在完成時(shí)表達(dá)的動(dòng)作常具有反復(fù)性，故下面一句是錯(cuò)的：
Have you seen the six thirty`s news program?
應(yīng)改為：
Did you see the six thirty`s news program?
