篇1:中考英语:现在完成时剖析

1.基本概念:表示过去发生的动作对现在造成的影响或结果;或表示过去已经开始,持续到现在的动作或状态。

2.基本构成:助动词have/has+过去分词

过去分词的变化规则:

规则动词的过去分词由动词原形加ed构成,不规则动词的过去分词

见不规则动词表(教师给学生复印)

3.中考考查范围:

1)yet, already, just, before, never, ever, recently等表示时间的词作时间状语,表示过去发生的动作对现在造成的影响或结果

天津中考:------What are you going to do this weekend?

-------I ____yet.

A.haven not decided B.will not decide C.have decided D.did not decide

2)since, for 引导的时间状语,表示过去已经开始,持续到现在的动作或状态

上海中考:The Oriental Pearl TV Tower________thousands of visitors since 1995.

A.attracted B.attracts C.has attracted D. Will attract

3)this morning, this week, today, now等时间状语用在现在完成时中

河北中考:-----______Betty this morning?

----Not yet, but she is sure to be here before noon.

A.Have you seen B.Will you see C.Do you see D.Did you see

4)have/has been to 与have/has gone to 的用法区别

河南中考:Mike ______the bookshop .I have to wait for him.

A.went to B.was in C. Has been to D.has gone to

4.现在完成时与一般过去时的区别:

现在完成时与一般过去时都表示过去的动作,但现在完成时强调这一动作与现在的关系,如对现在产生的影响、结果等;而一般过去时只表示过去的时间内发生的动作或存在的状态,就过去的时间方面讲,只能与一般过去时连用,而不能与现在完成时连用。

Tom has been busy now.汤姆现在很忙。(过去的动作对现在有影响)

Tom was busy last week.汤姆上星期很忙。(过去的动作对现在没有影响)

5.判断正误:

1)When have you got here?

When did you get here?

2) I have had bought the book two days ago.

I have had the book for two days.

3)I have just finished my homework.

I have finished my home work a moment ago.

4)Have you ever met an American before?

I have met an American last year.

瞬间性动词(也可叫点动词或不延续性动词)表示的动作瞬间即可结束,不能再延续,因此不能与表示延续性的时间状语连用。

5)I have left Wuhan for ten days.

I have been away from Wuhan for ten days.

It is (has been) ten days since I left Wuhan.

Two months has passed since we arrived here.

瞬间动词--------延续性动词:应逐一记忆

become-----be begin to study----study borrow-----keep

break------be broken buy---have close----be closed

come---be here die-----be dead go-----be away

get up---be up have got-have join---be in

篇3:中考英语倒装句剖析

1. 当句首为副词here ,there 且主语为名词时,应用完全倒装。

Here comes the bus.

There goes the bell.

2. only 修饰时间、地点、方式等状语时,应用部分倒装。

Only in this way can we solve the problem.

Only when you told me did I know her name.

注意:如果 only 修饰的不是状语,则句子不倒装。

Only Uncle Li knows how it happened.

3. 表示对前者的陈述也适用后者时,肯定倒装用 so + 助动词/情态动词 + 后者,前句事否定,而后面的人也不怎么样时用 neither / nor + 助动词 / 情态动词 + sb。

He can speak English,so can I.

If she doesnt go there tomorrow,neither / nor will I.

注意

1) so + 助动词 / 情态动词 + 主语 表示前者的主语和后者的主语的情况一样,所谈到的是两个人,意为也是这样

2) so + 主语 + 助动词 / 情态动词表示前者和后者所指同一人时,说话者表示同意前者的观点,意为的确如此。

- Li Lei likes sports.

- So he does and so do I.

4. 由 not only but also 引起的并列句,若将 not only 置于句首时,该分句应部分倒装, but also 引导的分句不倒装。

32、(2016陕西)My mother a good example for me since I was young.( )

A.was B.has been C.will be D.is

【考点】现在完成时.

【分析】从我小时候起,母亲一直是我的好榜样.

33、(2016荆门)---Do you know the scientist Tu Youyou?

---Yes,she is the first Chinese____won a Nobel prize in science.( )

A.who have B.that have C.which has D.that has

【考点】现在完成时.

【分析】--你了解科学家屠呦呦吗?

--是的,她是第一个在科学方面获得诺贝尔奖的中国人.

【解答】答案:D;

首先分析句子结构,本句中的“won a Nobel prize in science”在复合句中作定语从句,由于先行词the first Chinese 为下文定语从句的逻辑主语,且指人,所以引导定语从句的关系代词用that或者who,又由于先行词被 the first 序数词所修饰,所以引导词只能用that不能用who;另外注意定义从句的谓语动词由先行词决定,本题中,从句意为已经获奖,指过去发生的动作对现在造成的影响或结果,所以应用现在完成时,构成为has/have+过去分词;由于先行词是单数,所以助动词用has,故选D.

34、(2016济南)-I think our teacher.Mrs.Allen,knows everything.

-I agree.Because she over 2,000 books.( )

A.read B.has read C.reads D.is reading

【考点】现在完成时.

【解答】答案:B.

根据语境“因为她已经读了2000多本书了.”强调过去的动作对现在造成的影响,判断用现在完成时.现在完成时的构成是:主语+have/has+动词的过去分词;主语是she,助动词用has,故答案为B

A.is; was B.had been; is

C.was; has been D.has been; is

【考点】现在完成时.

【分析】这座博物馆在这里80多年了,它是这个城市里最古老的建筑之一.

【解答】答案:D.

第一个设空处,句中的时间状语“for+时段”是现在完成时的标志,现在完成时的构成是:主语+have/has+动词的过去分词; 第二个设空处表述的是一般性事实,所以用一般现在时,故答案为D.

36、(2016荆门)---Are you going to watch“Running Man”tonight?

A.see B.have seen C.will see D.am seeing

【分析】--今天晚上你打算看《跑男》吗?

--不,我跟我的父母只看过一次,我认为它并不刺激.

【解答】答案:B.

根据设空处后面的once结合语境“我跟我的父母只看过一次”,强调对现在造成的影响,判断用现在完成时.现在完成时的构成是:主语+have/has+动词的过去分词;主语是I,助动词用have,see的过去分词是seen.故答案为B

37、(2016淮安)Andy,with his parents,______ to Hong Kong,and they will stay there for a week.( )

A.have gone B.has gone C.have been D.has been

【考点】现在完成时.

【分析】Andy和她的父母一起去了香港,他们打算在那里待一个星期.

【解答】答案:B.

根据后面一句话,可知Andy和她的父母一起去了香港,并且还没有回来,所以用have/has gone to;have/has been to 则表示去过某地(已经回来);主语后面由with结构时,谓语动词由前面的主语决定单复数,根据主语Andy判断用助动词has.故选B

38、(2016黄冈)-How do you like Treasure Island,Lucy?

-It's so exciting that I _______ it twice.( )

A.am reading B.have read

C.was reading D.had read

【考点】现在完成时.

【分析】--Lucy,你觉得《金银岛》怎么样?

--很刺激,我已经读过两遍了.

【解答】答案:B.

根据设空处后面的twice,结合语境“我看过两遍了.”强调对于现在的影响,判断用现在完成时.现在完成时的构成是:主语+have/has+动词的过去分词;主语是I,助动词用have,故答案为B

39、(2016邵阳)One of my friends _____ moved to America,I miss her so much.( )

A.has B.have C.are

【考点】现在完成时.
