名師指點高考英語單選題解題訣竅
在高考英語中,單選題總是讓同學們迷茫、困頓、難以抉擇。如果做單選題掌握了一定的技巧,也能如魚得水了??纯疵麕熑绾沃更c迷津吧!
一、學會審題,注意把握問題的著重點
仔細審題是解題的最基本要求,疏忽大意很容易造成誤選。
---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:此題問題的著重點是“藝術品怎么啦”而不是針對“地震”而言,因此,最佳選項應為A。
二、結合上下語境,推出正確答案
此類題多為截取的生活場景,句式靈活,用詞地道,表現(xiàn)出用語言來解決實際生活的問題,因此,不能死套語法框框,而應重在對語境的理解和把握,進行具體情況具體分析,選出符合邏輯行文的正確選項。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:根據(jù)上下語境的線索推測出問話人“詢問對方是否需要幫忙”,因此答案應為C。
2.We have't enough books for______ ; some of you will have to share.
A. somebody
B. anyone
C. everybody
D. nobody
析:根據(jù)下文“some of you will have to share”可判斷出“書籍不夠每人一本”,因此正確選項為C。
三、抓住關鍵詞,打開解題的切入點
很多情況下,題干上會有一個關鍵詞的提示,只要快速鎖定該詞,不但能找準答案,而且還能節(jié)省寶貴的時間,提高解題速度。
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:根據(jù)關鍵詞“recent”判斷正確答案為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:根據(jù)關鍵詞“by”判斷,正確答案為C。
四、關注標點符號能快速鎖定最佳選項
英語的標點符號常常是我們借以判斷最佳選項的重要信號,因此,我們在審題時要特別注意它的功能,不同的標點有不同的作用。
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:根據(jù)逗號“,”的功能判斷,逗號的前部分要么是從句要么是非謂語動詞(短語)或獨立主格,此空應用被動結構,所以答案選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:破折號“——”相當于“and”,前后結構應保持平衡,因此答案為D。
五、巧妙運用“排除法”,既方便又快捷
有時四個選項中一眼掃過去,會發(fā)現(xiàn)有三個是不可能的,這時采用“排除法”是最明智不過的。
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“新總統(tǒng)現(xiàn)在的日子不好過”;“許多問題需要去解決”即發(fā)生在將來應用不定式,排除其余選項,正確答案為C。
六、采用“還原法”,再現(xiàn)廬山真面目
有些句子設題上具有一定的隱蔽性和迷惑性,原因是它已改變了原先的句式或省去了一些內(nèi)容,使我們從表面上不容易辨別出其句型結構,增加了理解的難度。這時巧妙使用“還原法”能大大降低句子的難度,使人豁然開朗,茅塞頓開。
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:此題用介詞“of”設陷阱,受定勢影響會誤選-ing形式,但若能把后面部分還原為“he thought of more questions to ask”,就能斷出正確答案為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:最后一句為省略句,補充完整為“…, if there are any.”,得知正確答案為A。
七、去掉插入語,化繁為簡
有時設題特意加上插入語,使句型顯得繁雜,這時只要去掉插入語,題干就簡單明了,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:去掉插入語“you know”就知道答案為C。
八、以邏輯為主線,敲定答案
留意非謂語動詞與句子主語的邏輯聯(lián)系能迅速圈定答案,如下題正確答案應為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、通過對比關系,鎖定目標
句中如含有though\althought\but \however\while等表示對比關系的詞時,我們就可根據(jù)前后的關系確定正答案。
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:根據(jù)轉(zhuǎn)折關系得知“設法做成了……”,故選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:通過前后內(nèi)容對比,“不喜歡看電視劇”與“仍然”是轉(zhuǎn)折關系,故用but.
十、掌握固定句型,許多問題可迎刃而解
鼓勵學生自己歸納在學習中常見的一些固定句式,這對于提高單選題的準確率及書面表達的規(guī)范性都有好處。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…”為固定句式,再結合“by”判斷這里應用被動,故選C。
