英語單詞是英語學習的基礎,許多學生在記單詞時經(jīng)常會出現(xiàn)各種問題,比如記住了英文卻不知道中文意思等等,下面小編給大家分享英語中情態(tài)動詞表推測的用法，希望能夠幫助大家!
英語中情態(tài)動詞表推測的用法（精選篇1）
一、確定被猜測時間，正確判斷動詞時態(tài)形式。
1.對現(xiàn)在或?qū)淼那闆r進行猜測，用“情態(tài)動詞+do”的形式;對現(xiàn)在或?qū)碚谶M行的情況進行猜測，用“情態(tài)動詞+be doing”的形式。如：
①He may/ might come tomorrow.明天他可能會來。(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)在進行)
④He may/ might be waiting for you when you get there tomorrow.明天你到那里時，他可能會在等著你。(將來進行)
2. 對過去或已發(fā)生的情況進行猜測，用“情態(tài)動詞+have done”的形式;對過去進行或現(xiàn)在完成進行的情況進行猜測用“情態(tài)動詞+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，他可能已在等你了。(過去完成進行)
二、把握猜測語氣特點，選擇恰當情態(tài)動詞。
1. 熟記情態(tài)動詞的語氣特點和用法限制。
1)表示肯定的猜測時，各情態(tài)動詞語氣強弱如下：
最強——must(一定)
will (很有可能)
would(很有可能)
ought to(應該，很有可能)
should(應該，很有可能)
can(可能)
could(可能)
may(可能)
最弱——might(可能)
2)表示否定的猜測時can't / couldn't語氣最強，指“不可能”;may / might not語氣最弱，意思是“可能不”。
3)一些情態(tài)動詞表猜測時的用法限制。
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，多指“客觀可能性”。如：
Lightning can be very dangerous.閃電可能會非常危險。
2. 把握題干猜測語氣的強弱。
題干中如果有客觀依據(jù)，應該選擇猜測語氣最強的情態(tài)動詞;如果沒有客觀依據(jù)，則應選擇猜測語氣最弱的情態(tài)動詞。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
本題中的猜測沒有客觀依據(jù)。說話人對是否會去參加聚會還沒拿定主意，去聽音樂會也僅僅是有可能而已。因此，應選語氣最弱項，答案為D。
另外，在特定的語境中，一些“情態(tài)動詞+have done”不再對一件事情是否發(fā)生進行猜測，而是對已發(fā)生的事表達自己的看法，有時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)，有時表示很委婉的責備。如：
You might have phoned me, though you were busy then.你再忙也該給我打個電話。
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;他是因為幫一個陌生人而晚點的。
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。

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