英語中情態(tài)動(dòng)詞表推測(cè)的用法篇2

一、確定被猜測(cè)時(shí)間，正確判斷動(dòng)詞時(shí)態(tài)形式。

1.對(duì)現(xiàn)在或?qū)淼那闆r進(jìn)行猜測(cè)，用“情態(tài)動(dòng)詞+do”的形式;對(duì)現(xiàn)在或?qū)碚谶M(jìn)行的情況進(jìn)行猜測(cè)，用“情態(tài)動(dòng)詞+be doing”的形式。如：

①He may/ might come tomorrow.明天他可能會(huì)來。(將來)

②He may/ might know it.他可能知道這事。(現(xiàn)在)

③He may/ might be waiting for you now.他可能正在等你。(現(xiàn)在進(jìn)行)

④He may/ might be waiting for you when you get there tomorrow.明天你到那里時(shí)，他可能會(huì)在等著你。(將來進(jìn)行)

2. 對(duì)過去或已發(fā)生的情況進(jìn)行猜測(cè)，用“情態(tài)動(dòng)詞+have done”的形式;對(duì)過去進(jìn)行或現(xiàn)在完成進(jìn)行的情況進(jìn)行猜測(cè)用“情態(tài)動(dòng)詞+have been doing”的形式。如：

①He might have seen the film yesterday.昨天他可能已看了那部影片了。(過去)

②He may/ might have arrived in Beijing by now.現(xiàn)在他可能已到達(dá)北京了。(現(xiàn)在完成)

③He might have been waiting for you when you phoned him.你給他打電話時(shí)，他可能已在等你了。(過去完成進(jìn)行)

二、把握猜測(cè)語氣特點(diǎn)，選擇恰當(dāng)情態(tài)動(dòng)詞。

1. 熟記情態(tài)動(dòng)詞的語氣特點(diǎn)和用法限制。

1)表示肯定的猜測(cè)時(shí)，各情態(tài)動(dòng)詞語氣強(qiáng)弱如下：

最強(qiáng)——must(一定)

will (很有可能)

would(很有可能)

ought to(應(yīng)該，很有可能)

should(應(yīng)該，很有可能)

can(可能)

could(可能)

may(可能)

最弱——might(可能)

2)表示否定的猜測(cè)時(shí)can't / couldn't語氣最強(qiáng)，指“不可能”;may / might not語氣最弱，意思是“可能不”。

3)一些情態(tài)動(dòng)詞表猜測(cè)時(shí)的用法限制。

must只用于肯定句;

may/ might一般不用于疑問句;

could可用于各種句式;而can多用于否定句、疑問句，用于肯定句時(shí)，多指“客觀可能性”。如：

Lightning can be very dangerous.閃電可能會(huì)非常危險(xiǎn)。

2. 把握題干猜測(cè)語氣的強(qiáng)弱。

題干中如果有客觀依據(jù)，應(yīng)該選擇猜測(cè)語氣最強(qiáng)的情態(tài)動(dòng)詞;如果沒有客觀依據(jù)，則應(yīng)選擇猜測(cè)語氣最弱的情態(tài)動(dòng)詞。如：

—Are you coming to Jeff's party?

—I'm not sure. I ________go to the concert instead.

A. must B. would C. should D.might

本題中的猜測(cè)沒有客觀依據(jù)。說話人對(duì)是否會(huì)去參加聚會(huì)還沒拿定主意，去聽音樂會(huì)也僅僅是有可能而已。因此，應(yīng)選語氣最弱項(xiàng)，答案為D。

另外，在特定的語境中，一些“情態(tài)動(dòng)詞+have done”不再對(duì)一件事情是否發(fā)生進(jìn)行猜測(cè)，而是對(duì)已發(fā)生的事表達(dá)自己的看法，有時(shí)具有一定的感情色彩。

①ought to/ should have done本該做(卻未做);oughtn't to/ shouldn't have done本不該做(卻做了)，含有“責(zé)備”之意。如：

You shouldn't have done that; I had warned you of that several times.我已多次警告你，你本不該那么做的。

②might have done本可以做(卻沒有)，有時(shí)表示很委婉的責(zé)備。如：

You might have phoned me, though you were busy then.你再忙也該給我打個(gè)電話。

③could have done本可能(卻沒有)如：

He could have caught the early bus, but he was delayed by helping a stranger.他本能夠趕上早班車;他是因?yàn)閹鸵粋€(gè)陌生人而晚點(diǎn)的。

④would(not) have done本想做(卻沒做)/本不想做(卻做了)。如：

I would have helped you, but I was too busy.我本想幫你，可我太忙了。

She sang an English song just now. 她剛才唱了一首英文歌。(sing是及物動(dòng)詞)

■動(dòng)態(tài)動(dòng)詞和靜態(tài)動(dòng)詞

根據(jù)詞義特點(diǎn)，行為動(dòng)詞可分為動(dòng)態(tài)動(dòng)詞和靜態(tài)動(dòng)詞。動(dòng)態(tài)動(dòng)詞表示動(dòng)作，如give, take, work, run等;靜態(tài)動(dòng)詞表示感覺、情感、內(nèi)心世界、相互關(guān)系等，如know, live, lie, exist, be, have, mean, seem, appear, sound, prove, concerns, hate, dislike, like, love, prefer, surprise, astonish, satisfy, contain, include, matter depend on, belong to, guess, suppose，imagine, believe, doubt, admire, envy等。

■延續(xù)性動(dòng)詞和非延續(xù)性動(dòng)詞

注：非延續(xù)性動(dòng)詞在肯定句中通常不與表示時(shí)間段連用的for短語連用。如：

[譯]他離開這里三天了。

[誤]He has left here for three days.

[正]He has been away from here for three days.

[正]He left here three days ago.

[正]It’s three days since he left.

■限定動(dòng)詞與非限定動(dòng)詞

限定動(dòng)詞在句中作謂語，有人稱和數(shù)的變化。非限定動(dòng)詞有動(dòng)詞不定式、動(dòng)名詞和分詞三種，在句中不能單獨(dú)作謂語，沒有人稱和數(shù)的變化(詳見非謂語動(dòng)詞一章) 。如：

The room needs cleaning. 這房間需要清潔了。(needs在句中用謂語，是限定動(dòng)詞;cleaning是動(dòng)名詞作needs的賓語，屬非限定動(dòng)詞)
