现在完成时与一般过去时的比较
the present perfect tense & the simple past tense
概念: 一般过去时和现在完成时的区别：
❖ 一般过去时表示在过去某个时间发生的动词或存在的 状态，也表示过去经常或反复发生的动作。
e.g. He came here yesterday.
❖ 现在完成时表示过去的动作（或状态）对现在产生的 影响和结果
e.g. He has broken his bottle.
一般过去时和现在完成时的区别：
1）构成不同 Tom went to London last year. Lily has been to London twice.
一般过去时的谓语动词用过去式，
Choose the right answer,please!
( C) 1.How long has Mr Turner worked in this school?
A.30 years. B. Since it was open. C.5 years.
( B ) 2.What month is it now?
— Yes, I have. 吃了。
（意即我现在饱了，不要再吃了。）
— When did you have it?
你什么时候吃的？ （说话人感兴趣的是“吃”这一动作发生在时。）
一般过去时常与具体的时间状语连用，现在完 成时常与模糊的时间状语连用，或无时间状语。
一般过去时的时间状语： yesterday, once, last week, ... ago, in 1980, in October, just now等具体的时间状语。 现在完成时的时间状语： for, since, so far, ever, never, just, yet, till, up to now, always等不确定的时间状语。
现在完成时的谓语用“助动词have /has +过去分词”
