2．情態(tài)動(dòng)詞的測試要點(diǎn)

　　從以上例題可以看出，四級(jí)語法對(duì)情態(tài)動(dòng)詞的測試大體有以下幾點(diǎn)。
1）情態(tài)動(dòng)詞的基本用法，如①④⑤。
2）情態(tài)動(dòng)詞 + 動(dòng)詞的完成形式的用法，如③⑥。
3）情態(tài)動(dòng)詞的推測性用法⑦。

3． 情態(tài)動(dòng)詞的應(yīng)對(duì)策略

　　情態(tài)動(dòng)詞的使用主要根據(jù)其所表達(dá)的含義。解題時(shí)注意以下幾點(diǎn)：

1）情態(tài)動(dòng)詞自身結(jié)構(gòu)要正確

　　結(jié)構(gòu)包括情態(tài)動(dòng)詞自身的搭配和其后的連帶成分。除ought外情態(tài)動(dòng)詞后接原形動(dòng)詞，測試中常將不同結(jié)構(gòu)的動(dòng)詞置于一起設(shè)干擾項(xiàng)，如①。四個(gè)選項(xiàng)都與請(qǐng)求有關(guān)，但would you mind后接動(dòng)名詞，一般說would you like to而不是will you like to，will you please后用原形動(dòng)詞，答案是would you please?

2）注意情態(tài)動(dòng)詞推測性用法中各個(gè)情態(tài)動(dòng)詞使用的句型是否與題干句型一致。

　　在情態(tài)動(dòng)詞的推測性用法中，must, can, may, might, could各用于不同的句型，應(yīng)注意分辨。具體使用規(guī)律為：
must只用于肯定句中。
can/could不能用語肯定句中。
may/might不能用語疑問句中。
另外還應(yīng)注意can't表示"不可能"，may not表示"可能不"。
考試時(shí)，如果有原因說明自己的猜測，一般應(yīng)該must, can't用而不是may, may not。如：
He can't have stolen the money; he is not such kind of person.
Some pleasant thing must have happened to him. He is so excited.

3） 注意推測性用法中謂語動(dòng)詞發(fā)生的時(shí)間。

如果推測的為過去的事情，情態(tài)動(dòng)詞后則用完成形式。
There must have been no one in, for nobody answered the phone.
如果推測的是正在進(jìn)行的事情，情態(tài)動(dòng)詞后則用動(dòng)詞的進(jìn)行形式。
They must be talking about something very secret.
如果推測的是現(xiàn)在的狀態(tài)等，情態(tài)動(dòng)詞后則用原形動(dòng)詞
He must be badly ill. He looks so pale.
如果推測的是將來發(fā)生的事情，情態(tài)動(dòng)詞后同樣用原形動(dòng)詞，這時(shí)，情態(tài)動(dòng)詞只能是may/might。
There may be a terrible storm in the following few days.

4） 注意"情態(tài)動(dòng)詞+動(dòng)詞的完成形式"所表達(dá)的意思與題干意思是否相符。

其它"情態(tài)動(dòng)詞+ 動(dòng)詞的完成形式"并不表示推測，而分別表示：
could have done本來能夠
He didn't take part in the competition, he _______ though.
A. won B. didn't win C. could win D. could have won
needn't have done 本來沒不要
You ________. There was plenty of time.
A. needn't hurry B. can't hurry
C. mustn't have hurried D. needn't have hurried
should/ought to have done 本來應(yīng)該
You _______ me earlier. I could have helped you.
A. should tell me B. should have told
C. need to tell D. needn't have told
shouldn't/oughtn't to have done 本來不應(yīng)該
You ____ him so closely; you should have kept your distance.
A. shouldn't follow B. mustn't follow (2000.6)
C. couldn't have been following D. shouldn't have been following
might have done 本來應(yīng)該（用來表示一種責(zé)備）
You ______ even though you were busy at that time.
A. might help him B. must have helped him
C. might have helped him D. should help him

　　這類題在設(shè)計(jì)干擾項(xiàng)時(shí)，一般都會(huì)有情態(tài)動(dòng)詞推測性用法的涉及，同學(xué)們應(yīng)注意分詞上下文的邏輯和語意關(guān)系。

5） 注意常用情態(tài)動(dòng)詞的基本句法和表意功能

　　其它常用動(dòng)詞的用法，如shall表示"命令"、"威脅"、"許諾"或征求許可，may/might as well等，同學(xué)們都應(yīng)多多注意其用法。

4． 自我訓(xùn)練

　　請(qǐng)同學(xué)們做《語法分冊(cè)》第十章測試題自檢。

四、 倒裝

　　倒裝結(jié)構(gòu)也是比較常見的一種句式，但考查的分量不大，考試都有哪些特點(diǎn)，如何應(yīng)對(duì)，首先讓我們一起來看一下近幾年的考題。

1．Test Yourself.

1) I could not persuade him to accept it, ___ make him see the
importance of it.(19995.1)
A. if only I could not B. no more than I could

A. had he arrived B. would he have arrived

responsibly.(19996.1)

參考答案：

1) D 2) C 3) A 4) B 5) A

2．倒裝測試范圍和應(yīng)對(duì)策略

　　倒裝分部分倒裝和全部倒裝，但從近幾年的測試來看，重點(diǎn)是部分倒裝。對(duì)于倒裝句型同學(xué)們所應(yīng)注意的就是在哪些情況下需要倒裝，并且如何倒裝。注意下面常見的倒裝條件。

1） 含有否定意味的詞置于句首，主謂倒裝。

　　同學(xué)們應(yīng)注意常用否定詞語，如：hardly, barely, not, seldom, little, few, nowhere, never, at no time, by no means, in no way, in no case, under no circumstances, not until, not only… but also.., neither … nor…等。如果是在從句的句首，則從句倒裝，如4）題。

2） only + 狀語置于句首，主謂倒裝。

　　Only后的狀語可以是單詞、短語，也可以是從句，要特別注意，從句并不倒裝，而是主句倒裝。如：
Only when the war was over was he able to get happily back to work.

3） Neither/So置于句首倒裝，表示"也/也不……"，如上面的2）3）題。

4） There/here/then或做狀語的地點(diǎn)副詞和地點(diǎn)介詞短語置于句首，要全部倒裝。如：
There stands a monument in the center of the square.
Down came a light form the ceiling when he was walking across the floor.
On the hay lay a wounded boy of not more than seventeen.

5） 現(xiàn)在分詞和過去分詞可提至句首構(gòu)成"分詞+ be + 主語+其它+的倒裝句式。如：
Enclosed in the letter was a photo of a beautiful girl.
Glooming in the test tube on the table was the mysterious something which they had been working so hard to find, radium.

6） so/such…. that句型中，so + 形容詞/副詞提前，主謂倒裝。如：
So boring was the speech that the audience all left halfway.
Such a noise did they make that the neighbors could not go to sleep at night.

3．自我檢測

　　請(qǐng)同學(xué)們根據(jù)《語法分冊(cè)》第二十二章練習(xí)自檢。

　　同學(xué)們，英語的語法是一個(gè)包容性很廣的話題，在這里我們很難窮盡四級(jí)考試中涉及的方方面面，語法能力的培養(yǎng)要靠同學(xué)們平時(shí)的訓(xùn)練。不管怎樣，希望我的講解對(duì)各位同學(xué)能有一定的幫助，愿同學(xué)們順利通過語法這一關(guān)。
