n

n

n   时间状语有:yesterday, last week, an hour ago, the other day, in 1982等。

n

n   Where did you go just now?

n

n   2)表示在过去一段时间内,经常性或习惯性的动作。

n

n   When I was a child, I often played football in the street.

n

n   Whenever the Browns went during their visit, they were given a warm welcome.

n

n   3)句型:

n

n   It is time sb. did sth. "时间已迟了"  "早该……了"

n

n   It is time for you to go to bed.  你该睡觉了。

n

n   It is time you went to bed.   你早该睡觉了。

n

n   would (had) rather sb. did sth. 表示'宁愿某人做某事'

n

n   4) wish, wonder, think, hope 等用过去时,作试探性的询问、请求、建议等。

n

n

n   比较:

n

n   一般过去时表示的动作或状态都已成为过去,现已不复存在。

n

n   Christine was an invalid all her life.

n

n   (含义:她已不在人间。)

n

n   Christine has been an invalid all her life.

n

n   (含义:她现在还活着)

n

n   Mrs. Darby lived in Kentucky for seven years.

n

n   (含义:达比太太已不再住在肯塔基州。)

n

n   Mrs. Darby has lived in Kentucky for seven years.

n

n   ( 含义:现在还住在肯塔基州,有可能指刚离去)

n

n   注意: 用过去时表示现在,表示委婉语气。

n

n   1)动词want, hope, wonder, think, intend 等。

n

n   Did you want anything else?

n

n   I wondered if you could help me.

n

n   2)情态动词 could, would.

n

n   Could you lend me your bike?

n

n   一般现在时的用法<二>

n

n   1) 经常性或习惯性的动作,常与表示频腮度的时间状语连用。

n

n   时间状语: every…, sometimes, at…, on Sunday

n

n   I leave home for school at 7 every morning.

n

n   2) 客观真理,客观存在,科学事实。

n

n

n   Shanghai lies in the east of China.

n

n   3) 表示格言或警句中。

n

n   Pride goes before a fall. 骄者必败。

n

n   注意:此用法如果出现在宾语从句中,即使主句是过去时,从句谓语也要用一般现在时。

n

n   例:Columbus proved that the earth is round..

n

n   4) 现在时刻的状态、能力、性格、个性。

n

n   I don't want so much.

n

n   Ann Wang writes good English but does not speak well.

n

n   比较:Now I put the sugar in the cup.

n

n   I am doing my homework now.

n

n   第一句用一般现在时,用于操作演示或指导说明的示范性动作,表示言行的瞬间动作。再如:Now watch me, I switch on the current and stand back. 第二句中的now是进行时的标志,表示正在进行的动作的客观状况,所以后句用一般现在时。

n

n   一般将来时<三>

n

n   1) shall用于第一人称,常被will 所代替。

n

n   will 在陈述句中用于各人称,在争求意见时常用于第二人称。

n

n   c. 有迹象要发生的事

n

n   3)  be +不定式表将来,按计划或正式安排将发生的事。

n

n   We are to discuss the report next Saturday.

n

n   4) be about to +不定式,意为马上做某事。
