高中英語語法：助動詞

一.概念:

助動詞是幫助主要?jiǎng)釉~構(gòu)成各種時(shí)態(tài),語態(tài),語氣以及否定或疑問結(jié)構(gòu)的動詞.助動詞分為時(shí)態(tài)助動詞和結(jié)構(gòu)助動詞兩種.

二.相關(guān)知識點(diǎn)精講:

1. 助動詞be的用法

1) be +現(xiàn)在分詞，構(gòu)成進(jìn)行時(shí)態(tài)。例如：

They are having a meeting.　他們正在開會。

English is becoming more and more important. 英語現(xiàn)在越來越重要。

2)　be + 過去分詞，構(gòu)成被動語態(tài)。例如：

The window was broken by Tom..　窗戶是湯姆打碎的。

English is taught throughout the world.　世界各地都教英語。

3) be + 動詞不定式，可表示下列內(nèi)容：

a. 表示較近、未來的計(jì)劃或安排。例如：

He is to go to New York next week..　他下周要去紐約。

We are to teach the freshmen.　我們要教新生。

說明： 這種用法也可以說成是一種將來時(shí)態(tài)表達(dá)法。

b. 表示命令。例如：

You are to explain this.　對此你要做出解釋。

He is to come to the office this afternoon.　要他今天下午來辦公室。

c.　征求意見。例如：

How am I to answer him?　我該怎樣答復(fù)他?

Who is to go there?　誰該去那兒呢?

d. 表示相約、商定。例如：

We are to meet at the school gate at seven tomorrow morning.　我們明天早晨7點(diǎn)在校門口集合。

2. 助動詞have的用法

1)have +過去分詞，構(gòu)成完成時(shí)態(tài)。例如：

He has left for London.　他已去了倫敦。

By the end of last month, they had finished half of their work.　 上月未為止，他們已經(jīng)完成工作的一半。

2)have + been +現(xiàn)在分詞，構(gòu)成完成進(jìn)行時(shí)。例如：

I have been studying English for ten years. 我一直在學(xué)英語，已達(dá)十年之久。

3)have +been +過去分詞，構(gòu)成完成式被動語態(tài)。例如：

English has been taught in China for many years. 中國教英語已經(jīng)多年。

3.助動詞do 的用法

1)構(gòu)成一般疑問句。例如：

Do you want to pass the CET?　你想通過大學(xué)英語測試嗎?

Did you study German?　你們學(xué)過德語嗎?

2)do + not 構(gòu)成否定句。例如：

I do not want to be criticized.　 我不想挨批評。

He doesn"t like to study.　 他不想學(xué)習(xí)。

In the past, many students did not know the importance of English.

過去，好多學(xué)生不知道英語的重要性。

3) 構(gòu)成否定祈使句。例如：

Don"t go there.　不要去那里。

Don"t be so absent-minded.　不要這么心不在焉。

說明： 構(gòu)成否定祈使句只用do，不用did和does。

4)放在動詞原形前，加強(qiáng)該動詞的語氣。例如：

Do come to my birthday party.　一定來參加我的生日宴會。

I did go there.　我確實(shí)去那兒了。

I do miss you.　我確實(shí)想你。

5)用于倒裝句。例如：

Never did I hear of such a thing.　 我從未聽說過這樣的事情。

Only when we begin our college life do we realize the importance of English. 進(jìn)了大學(xué)以后，我們才認(rèn)識到英語的重要性。

說明： 引導(dǎo)此類倒裝句的副詞有never, seldom, rarely, little, only, so, well等。

6)用作代動詞。例如：

---- Do you like Beijing?　--你喜歡北京嗎?

---- Yes, I do.　--是的，喜歡。(do用作代動詞，代替like Beijing.)

He knows how to drive a car, doesn"t he? 他知道如何開車，對吧?

4. 助動詞shall和will的用法

shall和will作為助動詞可以與動詞原形一起構(gòu)成一般將來時(shí)。例如：

I shall study harder at English.　 我將更加努力地學(xué)習(xí)英語。

He will go to Shanghai.　　他要去上海。

說明：在過去的語法中，語法學(xué)家說shall用于第一人稱，will 只用于第二、第三人稱。現(xiàn)在，尤其是在口語中，will常用于第一人稱，但shall只用于第一人稱，如用于第二、第三人稱，就失去助動詞的意義，已變?yōu)榍閼B(tài)動詞，試比較:

He shall come.　他必須來。(shall有命令的意味。)

He will come.　他要來。(will只與動詞原形構(gòu)成一般將來時(shí)。)

5.助動詞should, would的用法

1)should無詞義，只是shall的過去形式，與動詞原形構(gòu)成過去將來時(shí)，只用于第一人稱。例如：

I telephoned him yesterday to ask what I should do next week. 我昨天給他打電話，問他我下周干什么。

比較："What shall I do next week?" I asked. "我下周干什么?"我問道。

可以說，shall變成間接引語時(shí)，變成了should。

2) would也無詞義，是will的過去形式，與動詞原形構(gòu)成過去將來時(shí)，用于第二、第三人稱。例如：

He said he would come.　 他說他要來。

比較："I will go," he said. 他說："我要去那兒。"變成間接引語，就成了He said he would come。原來的will變成would，go變成了come.。

6. 短語動詞

動詞加小品構(gòu)成的起動詞作用的短語叫短語動詞。例如：

Turn off the radio.　把收音機(jī)關(guān)上。(turn off是短語動詞)

短語動詞的構(gòu)成基本有下列幾種：

1)動詞+副詞，如：black out;

2)動詞+介詞，如：look into;

3)動詞+副詞+介詞，如：look forward to。構(gòu)成短語動詞的副詞和介詞都統(tǒng)稱為小品詞

高中英語語法：情態(tài)動詞

一.概念:
