2021年高考英语语法 高考英语中最常考的八类状语从句

1、高考英语语法 高考英语中最常考的八类状语从句 状语从句是高考英语的必考考点，综观近年来各省市状语从句的考题情况，我们发现以下八类状语从句特别值得 _： 根据语境的不同，in case既可表示“如果”“万一”，引导条件状语从句;也可表示“以防(万一)”，引导目的状语从句。下面两道真题均选in case： 1. Leave your key with a neighbor _ you lock yourself out one day. (北京卷) A. ever sin _ B. even if C. soon after D. in case 2. My parents live in a s

2、 _ll village. They always keep candles in the house _ there is a power cut. (重庆卷) A. if B. unless C. in case D. so that 【解析】两道题都选in case，均表示“以防万一”。 尤其要注意“it+be+一段时间+before”这一句型。如： 1. The field research will take Joan and Paul about five months; it will be a long time _ we meet them again. (安徽卷) A. a

3、fter B. before C. sin _ D. when 2. He was told that it would be at least three more months _ he could recover and return to work. (江西卷) A. when B. before C. sin _ D. that 【解析】两道题均before。第1题涉及的句式为：It will be a long time before，意思是“要过很久才会”;第2题涉及的句式为：it was some time before，意思是“在之前过了一段时间”，通常可转译为“要过一段时间

4、才会”。 尤其要注意while表示“尽管”“虽然”时的用法(此时它引导的不是时间状语从句，而是让步状语从句此用法许多同学并不熟悉，值得特别注意!)。如： _ I really dont like art, I find his work impressive. (山东卷) A. As B. Sin _ C. If D. While 【解析】答案选D。while在此表示“尽管”“虽然”，又如：While the work was difficult, it was interesting. 尽管工作有难度，但很有趣。/ While I understand what you say, I can

5、t agree with you. 虽然我理解你的意思，但我还是不同意。 另外，while表示对比的用法也值得注意(此时它表示“而”)。如： The cost of living in Glasgow is among the lowest in Britain, _ the quality of life is probably one of the highest. (天津卷) A. sin _ B. when C. as D. while 对于when的用法，同学们最熟悉的是表示“当的时候”。如： Wheres that report? I brought it to you _ you

6、 were in Mr. Blacks offi _ yesterday. (北京卷) A. if B. when C. because D. before 【解析】答案选B。将四个选项逐一填入空格处，只有填when时，意思最通顺。句意为：当你昨天在布莱克先生办公室时我就带给你了。 但是when还有一个用法，就是表示“既然”。如： Why do you want a new job _D_ youve got such a good one already? A. that B. where C. which D. when 还有一点也需注意，就是when表示“这时(突然)”的用法。如： 1.

7、 I had just stepped out of the bathroom and was busily drying myself with a towel _B_ I heard the steps. (湖南卷) A. while B. when C. sin _ D. after 2. He was about halfway through his meal _C_ a familiar voi _ came to his ears. (辽宁卷) A. why B. where C. when D. while unless的意思是“如果不”“除非”，对于涉及unless的考题，一

8、般只要能读懂句意，弄清语境，一般不会有问题。如： 1. Most birds find it safe to sleep in the trees, but _ they have eggs or young chicks, they dont use a nest. (湖南卷) A. why B. how C. unless D. where 2. I wont call you, _ something unexpected happens. (全国I) A. unless B. whether C. because D. while 【解析】两道题都选unless，均表示“除非”。 un

9、til的意思是“直到时”“在之前”，对于涉及until的考题，一般只要能读懂句意，弄清语境，一般不会有问题。如： It is difficult for us to learn a lesson in life _A_ weve actually had that lesson. (天津卷) A. until B. after C. sin _ D. when 另外，还要注意notuntil这一句式(直到才)。如： “You cant have this football back _D_ you promise not to kick it at my cat again,” the old

10、 _n said firmly. (广东卷) A. because B. sin _ C. when D. until on _的意思是“一旦”，对于涉及on _的考题，一般只要能读懂句意，弄清语境，一般不会有问题。如： 1. You will be suessful in the interview _ you have confiden _. (福建卷) A. before B. on _ C. until D. though 2. _ enviro _ental da _ge is done, it takes _ny years for the ecosystem (生态系统) to recover. (江苏卷) A. Even if B. If only C. While D. On _ 【解析】两道题都选on _，均表示“一旦”。 where可以用于引导地点状语从句，其意为“在的地方”，此用法许多同学都不是熟悉，但高考经常考查，应引起特别注意。如： 1. If you are traveling _ the customs are really foreign to your own, please do as the Ro _ns do. (天津卷) A. in which B. what C. when D. where
