例如: does 做 goes 走,去 watches 观看

⑶ 新目标九年级英语第四单元重点语法

虚拟语气

一、概念

[Subjunctive Mood]
中文译作"虚拟语气"。它是一种动词形式,表示说话人的某种假设、愿望、怀疑、猜测、建议等含义。

二、语法结构
1.if结构(非真实条件句——表示的是假设的或实际可能性不大的情况)

与..事实相反 If从句 主句
过去 Had done Would* have done
现在 Were/did Would* do
将来 Should do/were/were to do Would* do

例句:If there hadn’t been much rain in spring, we would have had a good harvest now. [过去]
If he smoked less, his cough might be well soon. [现在]
If the lecturer should be late, you would have to make a speech first. [将来]

备注:
(1)上表中’would*’可转换为should、could、might。
(2) 如果为时间错综句的话,左右两栏可互相搭配,排列组合。
例句:
He would still be alive today if he hadn’t taken that drug.
[与现在事实相反] [与过去事实相反]

(3) if可转换为其他形式
例句:Without your advice, our meeting wouldn’t have been so successfully. [过去]
(=>可转换为:If there hadn’t been your advice, we …)
Your notes are almost illegible (难以辨认的). Notes typed out would be a lot easier to read. [将来]
(=> 可转换为:If the notes had been typed out, it would be a lot easier to read.)
I should have gone to see Dr. Smith and he might have cured me of the disease.[过去]
(=> 可转换为:If he have gone to see Dr. Smith, he ..)

2、wish结构

与..事实相反
过去 Had done
现在 Were/did
将来 Would

备注:可转换为其他形式。
例句:He talks as if (好像) he had done all the work himself. [过去]
I wish I were a bird.
I wish he handn' done that.
I wish I would be rich in the future.
3、should结构
从句中用“should + 动词原形”构成。而且should可以省去。用于此结构的动词有:advise, direct, agree, ask, demand, decide, desire, insist, order, prefer, propose, request, suggest,intend等。
例句:The teacher suggest he (should) read English aloud.

注意:当insist表示“坚持认为”、suggest表示“表明,显示”时,不用虚拟语气。

例句:The look on his face suggested that he was quite satisfied with what I had done for him.

He insisted that he was honest.

4、would rather +从句
在这种结构中,从句的谓语动词用过去形式表示虚拟。

例句:I would rather you did this instead of me.

5、主语从句中的虚拟语气

1)It be + 形容词 + that ...(should)...

用于该句型的形容词是:necessary, good, important, right, wrong, better, natural, proper, funny,
strange, surprising .

一些名词也可以用于 在该结构中。如:a pity, no wonder....

2)It be + 过去分词 + that ...(should)....

用于该结构中的过去分词是表示“建议、请求、命令”等词的过去分词。如:desired, suggested, requested,
ordered, proposed等。

3)It is time(about time, high time)that ...(过去式动词形式或should+动词原形)....

It is high time I went home now. = It is high time I should go home now.

6、表语从句、同位语从句中的虚拟语气
在suggestion, proposal, order, plan, idea, advice, decision等需要有内涵的名词后面的表语从句、同
位语从句中,要使用虚拟语气。其谓语动词应用:should+原形动词。另外连接从句的that不能省
略。

例:My suggestion is that we should go there at once.

What do you think of his proposal that we should put on a play at the English evening?

三、使用范围及判断
1、虚拟语气表示一种不能实现的假设。该语法主要用于if条件状语从句。也可用于主语从句、表语从句、宾语从句等。

2、if条件状语从句中虚拟语气的判断

判断是真实条件句还是非真实条件句。只有在非真实条件句中才使用虚拟语气。通过句子意思,看假设的条件是否能够实现,能够实现是真实条件句,不能使用虚拟语气;假设的条件不能实现则是非真实条件句,要用虚拟语气。

判断这个假设是与哪个事实相反。通常有三种情况:①与过去事实相反。②与现在事实相反。③与将来事实可能相反。

3、“后退一步法”

后退一步法是指在准确地判断了该句与哪一事实相反后,按虚拟语气的后退一步法处理从句谓语动词的时态。即:在非真实条件状语从句中,谓语动词按正常情况“后退一步”。也就是:

1)与过去事实相反,在从句中用过去完成时形式表示。

2)与现在事实相反,在从句中用过去一般时形式表示。

3)与将来事实可能相反,在从句中用过去将来时形式表示。

主句中则用情态动词would, should, could 等加一个与从句一致的动词形式。

例:If I had come her yesterday, I would have seen him.

If I were a teacher, I would be strict with my students.

If it should snow tomorrow, they couldn’t go out.

四、注意事项

1.if条件从句中如有were, should, had,可以省去if,并使用倒装语序。

2、在现代英语中if条件状语从句中的谓语动词如果是be其过去形式一般用were。

3、wish 后面宾语从句中的虚拟语气,按“后退一步法”处理从句的谓语动词。注意:与哪个事实相反,不能以主句的时态为判断依据,而是根据从句的意义判断。

3) 表示格言或警句。例如:

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。

例:Columbus proved that the earth is round. 哥伦布证实了地球是圆的。

4) 现在时刻的状态、能力、性格、个性。例如:

11.2 一般过去时的用法

1)在确定的过去时间里所发生的动作或存在的状态。例如:时间状语有:yesterday, last week, an hour ago, the other day, in 1982等。例如:

Mrs. Darby lived in Kentucky for seven years. (含义:达比太太已不再住在肯塔基州。)

Mrs. Darby has lived in Kentucky for seven years. (含义:现在还住在肯塔基州,有可能指刚离去)

返回动词的时态目录

11.10 比较一般过去时与现在完成时

1)一般过去时表示过去某时发生的动作或单纯叙述过去的事情,强调动作;现在完成时为过去发生的,强调过去的事情对现在的影响,强调的是影响。

2)一般过去时常与具体的时间状语连用,而现在完成时通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, last week,…ago, in1980, in October, just now等,皆为具体的时间状语。

现在完成时的时间状语:for, since, so far, ever, never, just, yet, till/until, up to now, in past years, always等,皆不确定的时间状语。

共同的时间状语:this morning, tonight, this April, now, already, recently, lately 等。

3)现在完成时可表示持续到现在的动作或状态,动词一般是延续性的,如live, teach, learn, work, study, know.。

一般过去时常用的非持续性动词有come, go, leave, start, die, finish, become, get married等。例如:

I saw this film yesterday. (强调看的动作发生过了)

I have seen this film. (强调对现在的影响,电影的内容已经知道了)

Why did you get up so early? (强调起床的动作已发生过了)

Who hasn't handed in his paper? (强调有卷子未交,疑为不公平竞争)

He has been in the League for three years. (在团内的状态可延续)

He has been a League member for three years. (是团员的状态可持续)

句子中如有过去时的时间副词(如yesterday, last, week, in 1960)时,不能使用现在完成时,要用过去时。

(错)Tom has written a letter to his parents last night.

(对)Tom wrote a letter to his parents last night.

返回动词的时态目录

11.11 用于现在完成时的句型

1)It is the first / second time.... that…结构中的从句部分,用现在完成时。例如:

It is the first time that I have visited the city. 这是我第一次访问这城市。

This is the first time (that) I've heard him sing. 这是我第一次听他唱歌。

注意:It was the third time that the boy had been late.

2)This is +形容词最高级+that…结构,that 从句要用现在完成时。例如:

This is the best film that I've (ever) seen. 这是我看过的最好的电影。

典型例题

(1) ---Do you know our town at all?

---No, this is the first time I ___ here.

A. was B. have been C. came D. am coming

答案B. This is the first time 后面所加从句应为现在完成时,故选B。

(2) ---Have you ____ been to our town before?

---No, it's the first time I ___ here.

A. even, come B. even, have come C. ever, come D. ever, have come

答案D. ever意为曾经或无论何时,反意词为never,此两词常用于完成时。

注意:非延续性动词的否定形式可以与表示延续时间的状语连用。即动作不发生的状态是可以持续的。

(错)I have received his letter for a month.

(对)I haven't received his letter for almost a month.

返回动词的时态目录

11.12 比较since和for

Since 用来说明动作起始时间,for用来说明动作延续时间长度。例如:
I have lived here for more than twenty years.我住在这儿二十多年了。
I have lived here since I was born. 我从出生起就住在这儿了。
注意:并非有for 作为时间状语的句子都用现在完成时。
I worked here for more than twenty years. (我现在已不在这里工作。)
I have worked here for many years.(现在我仍在这里工作。)
注意:用句型转换的方法,很容易排除非延续动词在有for/since结构的完成时中的误用。
1)(对) Tom has studied Russian for three years. = Tom began to study Russian three years ago, and is still studying it now.
2)(错) Harry has got married for six years. = Harry began to get married six years ago, and is still getting married now.
显然,第二句不对,它应改为 Harry got married six years ago. 或 Harry has been married for six years.

11.13 since的四种用法

1) since +过去一个时间点(如具体的年、月、日期、钟点、1980, last month, half past six)。例如:

I have been here since 1989. 1989起,我一直在这儿。

2) since +一段时间+ ago。例如:

I have been here since five months ago. 我在这儿,已经有五个月了。

3) since +从句。例如:

Great changes have taken place since you left. 你走后,变化可大了。

Great changes have taken place since we were here. 我们走后,变化可大了。

4) It is +一段时间+ since从句。例如:

It is two years since I became a postgraate student. 我考上研究生有两年了。

返回动词的时态目录

11.14 延续动词与瞬间动词

1) 用于完成时的区别

延续动词表示经验、经历; 瞬间动词表示行为的结果,不能与表示段的时间状语连用。例如:

He has completed the work. 他已完成了那项工作。 (表结果)

I've known him since then. 我从那时起就认识他了。(表经历)

2) 用于till / until从句的差异

延续动词用于肯定句,表示"做……直到……" 瞬间动词用于否定句,表示"到……,才……"。例如:

He didn't come back until ten o'clock. 他到10 点才回来。

He slept until ten o'clock. 他一直睡到10点。

典型例题

1. You don't need to describe her. I ___ her several times.

A. had met B. have met C. met D. meet

答案B. 首先本题后句强调对现在的影响,我知道她的模样,你不用描述。再次,several times告知为反复发生的动作,因此用现在完成时。

2. ---I'm sorry to keep you waiting.

---Oh, not at all. I ___ here only a few minutes.

A. have been B. had been C. was D. will be

答案A. 等待的动作由过去开始,持续到现在,应用现在完成时。

11.15 过去完成时

1) 概念:表示过去的过去

----|----------|--------|----> 其构成是had +过去分词构成。

那时以前 那时 现在

2) 用法

a. 在told, said, knew, heard, thought等动词后的宾语从句。例如:

She said (that)she had never been to Paris. 她告诉我她曾去过巴黎。

b. 状语从句

在过去不同时间发生的两个动作中,发生在先,用过去完成时;发生在后,用一般过去时。例如:

When the police arrived, the thieves had run away. 警察到达时,小偷们早就跑了。

c. 表示意向的动词,如hope, wish, expect, think, intend, mean, suppose等,用过去完成时表示"原本…,未能…"。例如:

We had hoped that you would come, but you didn't. 那时我们希望你能来,但是你没有来。

3) 过去完成时的时间状语before, by, until , when, after, once, as soon as。例如:

典型例题

The students ___ busily when Miss Brown went to get a book she ___ in the office.

A. had written, left B,were writing, has left C. had written, had left D. were writing, had left

答案D. "把书忘在办公室"发生在"去取书"这一过去的动作之前,因此"忘了书"这一动作发生在过去的过去,用过去完成时。句中when表示的是时间的一点,表示在"同学们正忙于……"这一背景下,when所引导的动作发生。因此前一句应用过去进行时。

注意: had hardly… when 还没等…… 就……。例如:

I had hardly opened the door when I he hit me. 我刚打开门,他就打了我。

had no sooner…than 刚…… 就……。例如:

He had no sooner bought the car than he sold it. 他刚买了这辆车,转眼又卖了。
