三．语法

1、 现在完成时 一、基本结构： 主语+have/has+过去分词(done) ①肯定句：主语+have/has+过去分词+其他 ②否定句：主语+have/has+not+过去分词+其他 ③一般疑问句：Have/Has+主语+过去分词+其他

回答用Yes, 主语+have/ has No, 主语+have/has not ④特殊疑问句：特殊疑问词+一般疑问句（have/has+主语+过去分词+其他）

二、用法

1） 现在完成时的\完成用法\

现在完成时用来表示现在之前已发生过或完成的动作或状态,但其结果却和现在有联系,也就是说,动作或状态发生在过去但它的影响现在还存在.

He has turned off the light.他已把灯关了。

(动作结束于过去，但说明的是现在的情况--灯现在不亮了。) I have spent all of my money.(含义是:现在我没有钱花了.) Jane has laid the table.(含义是:现在桌子已经摆好了.) 2） 现在完成时的\未完成用法\

指的是动作开始于过去某一时刻，一直延续到现在，或可能还要继续下去。这里的动词要用持续性动词。常与for（+时间段）,since（+时间点）连用.

Mary has been ill for three days. 三、have been to 和have gone to的区别

have been to 强调―去过‖，现已不在那里，如： He has been to the USA three times. 他到美国去过三次。（过去―到美国‖，现在已―不在美国‖）

have gone to主要强调的是―去了‖，现在人不在说话的现场，如： -Where's your mother? --你妈妈在哪？

-She has gone to the hospital. --她去医院了。 has been in 一直在某地 四、现在完成时总结

（1）与表示一段时间的状语连用，如― for +时间段‖ ― since +时间点‖。例如： We have lived in this city for more than 40 years. We have lived in this city since 1958.

(2)与表示包含过去和现在的一整段时间的状语连用，如 lately, recently, in the past few years, these few years, these days, up to now, so far 等。例如： How have you been recently ？ 你近来状况如何？

The famous writer has written a new book in the past two years. 那位著名的作家在过去的两年里写了一本新书。

(3)与笼统表示过去时间的状语连用，如 already, never, ever, just 等。含有这类时间状语的句子，其谓语动词表示句中的行为或动作发生在过去，但对现在有影响。例如： I've just found this library book. 我刚刚找到这本图书馆的书。 have found 这一动作发生在过去，但影响到现在，即现在图书馆的书在我这儿。 just 所表示的―刚才‖是与现在有密切相关的过去时间。

How beautifully she sings! I have never heard a better voice. 她唱得多美啊！我从来没听到过比这更优美的歌喉。

never 表示广义的过去，而且一直到目前才截止。 注意:

1.现在完成时不能单独与准确时间连用，(如表示过去的时间状语）如yesterday(morning、afternoon),last(morning、afternoon)等，除非与for, since连用.

2.现在完成时往往同表示不确定的过去时间状语连用

如already（肯定）, yet（否定，疑问）, just, before, recently, still, lately等: He

has already obtained a scholarship.

I haven't seen much of him recently (lately). We have seen that film before.

Have they found the missing child yet ?

3. 现在完成时常常与表示频度的时间状语连用, 如ever, never, twice, several times等: Have you ever been to Beijing

I have never heard Bunny say anything against her. I have used this pen only three times. It is still good. George has met that gentleman several times.

4.现在完成时中延续性的动作或状态和由for / since 引导的一段时间状语搭配使用。 “for + 时间段” 与 “since + 时间点” 都表“一段时间”，常用How long 提问。 如: ----How long have you been like this?

----I have been like this since last month./ for a month. ----How long have you lived in Changle?

----I have lived in Changle for ten years / since ten years ago. ※ 常见的非延续性动词转换成延续性动词如下： 短暂性动词 延续性动词

come -------- be leave -------- be away (from) get to know -------- know die -------- be dead buy -------- have begin -------- be on borrow -------- keep marry -------- be married

catch a cold -------- have a cold close -------- be closed join -------- be a member of / be in fall ill -------- be ill 一般过去时和现在完成时的区别

一般过去时表示过去某时发生的动作或单纯地叙述过去的事情，而现在完成时表示过去发生的动作对现在造成的影响或结果，强调的是现在的情况。

一般过去时常与果实的时间状语连用，比如：yesterday, last week, three hours ago, in 2006,而现在完成时不能和明确表示过去的时间状语连用。 五、现在完成时考点例析

现在完成时是较难掌握、中考考查较多的时态。涉及的考点有： 一、考查其构成

\助动词have (has) +动词过去分词\构成现在完成时。如： 1. Kate's never seen Chinese films，____ ? A. hasn't she B. has she C. isn't she D. is she

析：陈述句部分含否定词never,简略问句部分要用肯定式，又因Kate's是Kate has的缩写，故选B。

2. His uncle has already posted the photos to him. (改为否定句)

His uncle ______ posted the photos to him ______.

析：already常用在肯定句中，yet常用在否定句、疑问句中，故填hasn't, yet。 3. -Ann has gone to Shanghai. -So ______her parents. A. has B. had C. did D. have

析：\助/系/情态动词+主语\结构中的动词形式应与前句结构中动词形式保持一致，又后句的主语为her parents是复数,故选D。 二、考查其用法与标志词

(一)当句中有never, ever, just, already, yet, before等时，常用现在完成时。如： 1. -Mum, may I go out and play basketball? -______you______ your homework yet?

A. Do; finish B. Are; finishing C. Did; finish D. Have; finished 2. -______ you ______anywhere before? -Yes, but I can't remember where I______ A. Did; surf; surfed B. Have; surfed; surfed

C. Did; surf; have surfed D. Have; surfed; have surfed

(二)当句中有\段时间\或\点时间\等时，主句常用现在完成时，谓语动词必须是延续性动词，若是非延续性动词，要改为延续性动词或表状态的词(短语)。如： 1. His brother has been to Stone Forest twice ______ he came to Yunnan. A. after B. before C. since D. for 2. Tom ______ the CD player for two weeks.

A. has lent B. has borrowed C. has bought D. has had 3. I ______ a letter from him since he left.

A. didn't receive B. haven't got C. didn't have D. haven't heard 析：据since可知，应排除A、C，\意为\收到某人的来信\，故选B。

三、考查have/has been (to, in)/have/has gone (to)的区别。 如：

1. -Have you ever______ Lintong to see the Terra Cotta Warriors? -Yes, I have. A. went to B. gone to C. been in D. been to 2. My parents ______ Shandong for ten years.

A. have been in B. have been to C. have gone to D. have been 四、考查现在完成时与其他时态的联系和区别。
