The Present Perfect Tense( 现在完成时态 )
.

.现在完成时态的构成:

have/has+过去分词!

现在完成时的基本用法
(一)现在完成时表示过去某时发生的动作到说 话时已经完成,对现在产生的影响或结果。 可用 一个一般过去时和一个一般现在解释。

这种用法一般不带明显的时间状语,但可以 already ,yet, just, once, twice等副词用
eg:

She has had lunch. She is full now.(现在的情况) She had it an hour ago.(过去的动作) (现在完成时把过去的动作和现在联系起 来并着眼于现在)

(二)未完成用法。表示动作或状态开始于 过去, 一直 延续到现在,这个动作并未结束还会继续延续下去。 这种用法一般可以与表示延续性的时间壮语连用,如 (1)for+数词+时间名词 e g. You have learnt/ed English for over three years. Mrs luo has taught Chinese for about 30 years. He has done his homework for an hour. (2)since+ 时间点/具体的过去时间 e g. You have learned English since 2003.

He has been in the army for ten years. He has lived here since 1977. He has lived here for 29 years.

B:since+S(主)+V-ed+others. You have learnt English since you came to No.1Middle School.
从上面的句子可以得出:现在完成时的第二种用法的两种时间 状语可以转换,同时还可与一般现在时和一般过去时进行转换.

He has lived here for 29 years.

1977
常用的时间状语:

now

since…, for…, all one’s life in the past/last few years, so far,.

for 和since的运用对比:
for: +一段时间 for two weeks for three years since 过去的某一时刻 since then since last month 一般过去时态的时间状语从句 since she left

注意:for 和since 所引导的时间状语都表示一段时间.
He has been away for a week. 对划线部分提问都用

He has been away since last week. How long

3.Special usage: a.要表示某人曾去过某处,或去过某处多少 次。要用have/has been to +a place
She has ever been to Beijing. (现在已不在北京,从结果上和现在联系起来) b.要表示某人一直在某处。

She has been in Beijing for two years. (现在仍在北京,从时间上和现在联系起来) I have been in this town since 1977.

c. 要表示某人到某地去了。即说话人不在 说话的地点。

He has gone to Shanghai. 他已经去了上海。
Ex: Say ―W‖or ―R‖ to the following sentences。 You have gone to Shanghai.( W)

Your pen-friend,Tom has gone to Shanghai. ( R) I have gone to Shanghai.( W )

Examination point: Say ―W‖ or ―R‖ to the following
sentences. A.He has bought a book.( R ) He hasn’t bought any books for a long time. ( R ) He has bought the book for two weeks.( W ) He has had the book for two weeks. ( R )

B.The old man has died. ( R ) The old man has died for two years. ( W ) The old man has been dead for two years. ( R )

结束性动词在陈述句中不能和表示一

段时间的时间 状语连用,但是可以转换成对应的延续性动词后接段 时间. 结束性动词与延续性动词的转换:
buy– have catch (get) a cold –have a cold

borrow—keep

come/go /become—be

put on--

wear
join the army – be a soldier / be in the army go to school– be a student/ be in school finish – be over begin—be on leave—be away fall sleep – be asleep close – be closed die—be dead

一般过去时态和现在完成时态同义转换
