2017届河北省衡水名校高考英语一轮复习撬题对点练：专题12 特殊句式（3）（含解析）

　　A．单句填空

　　1．Video games can be a poor influence if ________ (leave) in the wrong hands.

　　答案　left　 [句意：电子游戏如果落入不对的人的手里就可能有坏的影响。这里考查了leave作及物动词的用法，可以理解为if (the video games are) left in the wrong hands，主从句的主语相同，省略从句中的主语和be动词。]

　　2．Always ________ (keep) in mind that your main task is to get this company running smoothly.

　　答案　keep　[句意：永远记住：你的主要任务就是让这个公司顺利运作。句子没有主语且表示命令，故为祈使句，答案为keep。]

　　3．Give me a chance, ________ I'll give you a wonderful surprise.

　　答案　and　[句意：给我一次机会，我会给你一个惊喜。本题考查特殊句式中的“祈使句＋and＋陈述句”句式。故填and。]

　　4．________(make) what you're doing today important, because you're trading a day of your life for it.

　　答案　Make　 [句意：让你今天做的事情有意义，因为你

　　正拿你生命中的一天来换取它。本题考查特殊句式。根据句意可知前半句为祈使句，用来给别人提建议，故填动词原形Make。]

　　5．This is a really lively party. There is a great atmosphere，________ there?

　　答案　isn't　[句意：这真是一个活跃的聚会，这有很好的气氛，是吗？根据分析，这是there be句型的反意疑问句，前半句肯定，附加句否定。]

　　B．单句改错

　　1．Observing carefully if any change occurs when doing experiments in the lab.

　　________________________________________________________

　　答案　Observing→Observe　[分析句子结构可知，主句为祈使句，故用Observe。]

　　2．—I spent two weeks in London last summer.

　　—Then you must have visited the British Museum during your stay, mustn't you?

　　________________________________________________________

　　答案　mustn't→didn't　[答语为反意疑问句，must have done表示对过去的肯定推测，且根据时间状语last summer可知用didn't。]

　　3．Read this story, or you will realize that not everything can be bought with money.

　　________________________________________________________

　　答案　or→and　[句意：读这个故事，你会意识到并非所有的东西都能用钱买到。本题考查“祈使句＋and/or＋陈述句”句型。该句型中两个分句如果用and连接，祈使句相当于if引导的肯定形式的条件状语从句；如果两个分句用or连接，祈使句相当于：If... not...。本句题干可改为：If you read this story, you will realize that not everything can be bought with money.。]

　　4．Every day reading a proverb aloud several times until you have it memorized.

　　________________________________________________________

　　答案　reading→read　[分析句子结构可知，此句为祈使句，故用read。]

　　易错题一：句型“It＋be＋时间＋since/before/that/when...”的误用

　　[例1]　It is three years ________ he worked here and now he works in another city.

　　[错解]　that/when/before

　　[错因分析]　本题易错填before, that或when，原因可能是考生将句子理解成了一个强调句或者含有when/before的句型等。

　　[答案]　since

　　[心得体会]

　　[例2]　British people are not so patient as before. It lasts an average of 8 minutes and 22 seconds ________ they lose their temper，according to a new research.

　　[错解]　when

　　[错因分析]　本题易误用when，原因可能是考生没有理解此题的语境，也没对句子的时态进行分析。此处用before, before作连词，意为“在……之前”，表示动作发生的顺序。句意：英国人不像以前那么有耐心了。新的研究表明，平均每8分22秒他们就会发脾气。

　　[答案]　before

　　[心得体会]

　　易错题二：so/such...that...中so与such的误用

　　[例]　It was ________ fine weather that they all went swimming.

　　[错解]　so

　　[错因分析]　考生可能只注意到了形容词fine，而忽视了fine weather的中心词是名词weather，因而误用so。

　　[答案]　such

　　[心得体会]

　　易错题三：It is/was not until...that强调句型的误用

　　[例]　It was not until all the fish died in the river ________ the villagers realized how serious the pollution was.

　　[错解]　when

　　[错因分析]　本题易误用when，原因可能是考生没有掌握It is/was not until...that句型。

　　[答案]　that
