一、学会审题,注意把握问题的着重点

仔细审题是解题的最基本要求,疏忽大意很容易造成误选。

---What happened to the priceless works of art?

--- _______.

A. They were destroyed in the earthquake

B. The earthquake was destroying them

C. They destroyed in the earthquake

D. The earthquake destroyed them

析:此题问题的着重点是“艺术品怎么啦”而不是针对“地震”而言,因此,最佳选项应为A。

二、结合上下语境,推出正确答案

此类题多为截取的生活场景,句式灵活,用词地道,表现出用语言来解决实际生活的问题,因此,不能死套语法框框,而应重在对语境的理解和把握,进行具体情况具体分析,选出符合逻辑行文的正确选项。例:

1. ---You seem to have lost your way. _______?

---Yes, I'm looking for Wangfujing Street.

A. Are you looking for something

B. Where are you going

C. Need help

D. What are you looking for

析:根据上下语境的线索推测出问话人“询问对方是否需要帮忙”,因此答案应为C。

2.We have't enough books for______ ; some of you will have to share.

A. somebody

B. anyone

C. everybody

D. nobody

析:根据下文“some of you will have to share”可判断出“书籍不够每人一本”,因此正确选项为C。

三、抓住关键词,打开解题的切入点

很多情况下,题干上会有一个关键词的提示,只要快速锁定该词,不但能找准答案,而且还能节省宝贵的时间,提高解题速度。

1.Years ago, we didn't know this, but recent science______that people who don't sleep well soon get ill.

A. showed

B. has shown

C. will show

D. is showing

析:根据关键词“recent”判断正确答案为B。

2.The group, ____ by Tseng Yungchuan, arrived in Beijing on Wednesday to help push for Taiwan to be opened to mainland tourists.

A. leads

B. leading

C. led

D. having led

析:根据关键词“by”判断,正确答案为C。

四、关注标点符号能快速锁定最佳选项

英语的标点符号常常是我们借以判断最佳选项的重要信号,因此,我们在审题时要特别注意它的功能,不同的标点有不同的作用。

1、--- ______ a second time, will the man have one more try?

--- I'm sure he will.

A. Turn down

B. If turning down

C. He was turned down

D. If turned down

析:根据逗号“,”的功能判断,逗号的前部分要么是从句要么是非谓语动词(短语)或独立主格,此空应用被动结构,所以答案选D。

2. _____ some exercise every day —I'm sure you'll get fit sooner or later.

A. To take

B. taking

C. Have taken

D. Take

析:破折号“——”相当于“and”,前后结构应保持平衡,因此答案为D。

五、巧妙运用“排除法”,既方便又快捷

有时四个选项中一眼扫过去,会发现有三个是不可能的,这时采用“排除法”是最明智不过的。

With a lot of difficult problems ______, the newly-elected president is having a hard time.

A. settled

B settling

C. to settle

D. being settled

析:既然“新总统现在的日子不好过”;“许多问题需要去解决”即发生在将来应用不定式,排除其余选项,正确答案为C。

六、采用“还原法”,再现庐山真面目

有些句子设题上具有一定的隐蔽性和迷惑性,原因是它已改变了原先的句式或省去了一些内容,使我们从表面上不容易辨别出其句型结构,增加了理解的难度。这时巧妙使用“还原法”能大大降低句子的难度,使人豁然开朗,茅塞顿开。

1、The more he thought about it, the more questions he thought of_____.

A. to be asked

B. being asked

C. asking

D. to ask

析:此题用介词“of”设陷阱,受定势影响会误选-ing形式,但若能把后面部分还原为“he thought of more questions to ask”,就能断出正确答案为D。

2. ---Can I help you?

---Yes, please. Do you have any books on cooking?

---There are only a few, _______.

A. if any

B. if have

C. if some

D. if do

析:最后一句为省略句,补充完整为“…, if there are any.”,得知正确答案为A。

七、去掉插入语,化繁为简

有时设题特意加上插入语,使句型显得繁杂,这时只要去掉插入语,题干就简单明了,一目了然了。

---Is that the small town you often refer to?

---Right, just the one_____ you know I used to work for years.

A. that

B. which

C. where

D. what

析:去掉插入语“you know”就知道答案为C。

八、以逻辑为主线,敲定答案

留意非谓语动词与句子主语的逻辑联系能迅速圈定答案,如下题正确答案应为C。

While watching television, ________.

A. the doorbell rang

B. a black cat suddenly ran in

C. we heard the doorbell ring

D. an unexpected visitor came to visit me

九、通过对比关系,锁定目标

句中如含有though\althought\but \however\while等表示对比关系的词时,我们就可根据前后的关系确定正答案。

1. They wanted to charge $5000 for the car, but we ______to bring the price down.

A. tried

B. managed

C. failed

D. had

析:根据转折关系得知“设法做成了……”,故选B。

2.---I think George does't really care for TV plays.

---Right, _____ he still watches the program.

A. and

B. but

C. or

D. so

析:通过前后内容对比,“不喜欢看电视剧”与“仍然”是转折关系,故用but.

十、掌握固定句型,许多问题可迎刃而解

鼓励学生自己归纳在学习中常见的一些固定句式,这对于提高单选题的准确率及书面表达的规范性都有好处。如,“祈使句+and\or + Sb. will …”;“It +be +some time +before …”;“It wasn't until…that…”等。

The flu is believed_____by viruses that like to reproduce in the cells inside the human nose and throat.

A. causing

B. being caused

C. to be caused

D. to have caused

析:“Sth.\Sb. be said \believed to +V…”为固定句式,再结合“by”判断这里应用被动,故选C
