2023年初中英语状语从句考点分析与专题训练比较状语从句知识点归纳总结一、在英语状语从句学习中，有一种从句是由：原级：as…as（和……一样），not so（as）…as …（和不一样）；比较级：more…than（更）；最高级：The most…in/of， the + 形容词+est…of/in。常用引导词：as（同级比较），than（不同程度的比较）；特殊引导词：the more … the more … ； no … more than；not A so much as B引导的，由这类词引导的状语从句叫做比较状语从句，主要运用于形容词和副词的原级、比较级及最高级的句子之中。二、1、as/so + 原级 + as；它的意思是， 和......一样,（其中 as/so 是副词,意思是“同样地”,后一个 as 是连词）,如：My hometown is as/so beautiful as Hangzhou我的家乡和杭州一样美。2、no + 比较级 + than ，它的意思是，最多和......一样，只不过，如：I have no more than two dollars left in my pocket.我口袋里只剩下两元钱了.（有钱少的含义）3、not more than,不多于,如：I have not more than two dollars left in my pocket.我口袋里顶多还有两元钱.（没有钱多钱少的含义）4、no less than 不亚于,至少和...一样,如：He has got no less presents than I did last time.他收到的礼品不亚于我上次收到的.（有收到多的含义）5、not less than 不少于,如：He has got not less presents than I did last time.他收到的礼品不少于我上次收到的.（不包含多或少的含义）6、比较级 + than,比...优上,如：Our class is bigger than yours.我们班的规模比你们的大.7、the 比较级 + the 比较级,越如何就越如何,如：The more we can do for you,the happier we will be.为你们做得越多我们就越感到高兴.8、less + 原级 + than,不如,比...较差,如：This kind of food is less expensive than that one.这种食品不如那一种贵.9、not so + 原级 + as,不如,不及,如：The film today is not so interesting than the one yesterday.今天的电影不如昨天的那个有意思.10、than 比,as/so ...as 和...一样,the more...the more 越...越...三、比较状语从句从某种角度上说，它也是一种方式状语从句，它通常可和以下关联词来引导as(或so)...as, than, according as, in proportion as等。1. He woke up as suddenly as he had fallen asleep.他醒来得和入睡一样突然。(第一个as是副词)2. I have never seen so much rain as fell that February.我从未见过像那个二月那么多雨。(否定结构常用so…as, 也可用as... as)3. Man developed earlier than people think.人类的出现比人们所想的要早。4. He moves more slowly than his sister does.他行动起来比他妹妹慢。5. The youth of today are better off than we used to be.今天的年轻人比我们过去的境况要好。6.

Heavily as it was raining outside, they started out very early. 　尽管外面下雨非常厉害，但是他们早早就开始了。2. Young as he is, he knows a lot=Though he is young 或Young though he is, he…. 　　他虽然年轻,但懂得很多。　　3. Object as/though you may， I’ll go.(=Though/Although you may object， I’ll go.)纵使你反对，我也要去。4. Hard as/ though he works， he makes little progress. (=Though he works hard，he makes little progress.）尽管他学习很努力，但几乎没取得什么进步。5. Child as/though he was， he knew what was the right thing to do.（=Though he was a child，he knew what was the right thing to do.）虽然他是一个孩子，但他知道该做什么。6. Fast as you read， you can’t finish the book so soon.纵然你读得快，你也不能这么快读完这本书。7. Lover of towns as I am， I realize that I owe a debt to my early country life.尽管我爱城市，但我知道，以往的乡村生活使我受益匪浅。8. Small as atome are， they are made up of still smaller units.尽管原子很小，但它们由更小的单位构成。英语基础语法专练1. The farmer watered the vegetables in the field _____ they might grow better.A. in case                        B. for fear thatC. in order                       D. so that2. If they don’t understand it the first time, go over it again _____ they do.A. when                          B. afterC. since                           D. until3. I won’t accept their offer, _____ favorable the conditions.A. how                            B. howeverC. no matter                     D. no matter however4. _____ it happened to be a nice day, we decided to go to the beach.A. When                          B. BeforeC. If                                D. Since5. We were just about ready to leave _____ it started to snow.A. when                          B. beforeC. after                           D. since6. I’ll keep his address _____ I need it.A. so that                        B. in order thatC. in case                        D. when7. Will you keep my place in the queue for me _____ I go and make a phone call?A. since                           B. whileC. in case                        D. until8. _____ I’m very much mistaken, that’s my watch you’re wearing!A. If                               B. UnlessC. Since                          D. Because9. The mother don’t let the boy touch the knife _____ he might cut himself.A. in order that                 B. so as thatC. for fear                        D. that10. The modern history of Italy dates from 1860, _____ the country became united.A. when                           B. ifC. since                            D. until11. We can’t move into the new flat _____ the other tenants have moved out.A. since                            B. whenC. until                             D. as12. When I met him last week, it was the first time we had seen each other _____ we were at school.A. that                              B. sinceC. when                           D. after13. She made a note of it _____ she might forget.A. so that                         B. in order thatC. if                                 D. in case14. The fire went on for quite some time _____ it was brought under control.A. when                           B. sinceC. after                            D. before15. They sat down opposite each other, but it was some moments _____ they spoke.A. after                            B. beforeC. since                           D. when16. _____ the government agrees to give extra money , the theatre will have to close.A. Until                            B. UnlessC. Since                           D. While17. ______ I suggest, he always disagrees.A. However                      B. WhateverC. Whichever                    D. Whoever18. Their country has plenty of oil, _____ ours has none.A. while                            B. whenC. unless                           D. since19. “______when do the pubs stay open?” “About midnight.”A. Since                            B. BeforeC. Until                             D. After20. ______ I understand what you say, I can’t agree with you.A. Since                            B. BecauseC. If                                 D. While 21. You should let your children play ______ you can see them.A. where                           B. whenC. in which                        D. that22. They kept trying _____ they must have known it was hopeless.A. if                                  B. becauseC. when                            D. where23. _____ you are at home alone, please don’t leave the door open.A. While                            B. AsC. Before                           D. How【参考答案】1—5 DDBDA  6—10 CBBCA  11—15 CBDDB 16—20 BBACD 21—23 ACA
