初二英语-状语从句

状语从句   (一)．原因状语从句是表示原因或理由的，引导这类从句的最常用的连词是because, since, as , now that（既然）等，for 表示因果关系时（它引导的不是从句）为并列连词，语气不如because强。   e.g. He is disappointed because he didn't get the position.   As it is raining, I will not go out. 　Now that you mention it, I do remember.  注意，because ,so 不能同时使用 （二）地点状语从句   引导地点状语从句的连词是where 和wherever等。   e.g. Sit wherever you like.    Make a mark where you have a question.   （三）目的状语从句   引导目的状语从句最常用的词（组）是so, so that（从句谓语常有情态动词）, in order that, in case（以防，以免）等。e.g. Speak clearly, so that they may understand you.   She has bought the book in order that she could follow the TV lessons. He left early in case he should miss the train. （四）结果状语从句结果状语从句是表示事态结果的从句，通常主句是原因，从句是结果。由so that （从句谓语一般没有情态动词）, so … that, such … that等引导。   e.g.1. She was ill, so that she didn’t attend the meeting.   2.He was so excited that he could not say a word.   3.She is such a good teacher that everyone admires her.   （七）让步状语从句   让步状语从句可由although, though, as, even if (though), however, whatever, whether … or, no matter who (when, what, …) 等引导。注意：as引导的让步状语从句一般是倒装的。e.g. Though he is a child, he knows a lot.   Child as he is, he knows a lot.   Whatever ( = No matter what ) you say, I’ll never change my mind.   （五）方式状语从句   方式状语从句常由as, as if (though), even if(though)等引导。   e.g. You must do the exercise as I show you. 　He acted as if nothing had happened.   （六）比较状语从句   比较状语从句常用than, so (as) … as, the more … the more等引导。   e.g. I have made a lot more mistakes than you have.   He smokes cigarettes as expensive as he can afford.  The busier he is, the happier he feels. (七）条件状语从句  条件状语从句分真实性（有可能实现的事情）与非真实性（条件与事实相反或者在说话者看来不大可能实现的事情）条件句。引导条件状语从句的词（组）主要有if, unless, so (as) long as, （只要）so (as) far as （正如…）。注意：条件从句中的if 不能用whether替换。if引导的条件状语从句结构：if＋一般现在时，主语＋将来时  含义：如果……，将要……例如：如果你请求他，他会帮助你。If you ask him, he will help you. 如果需要，我们就干个通宵。  If need be, we’ll work all night. If he is not in the office, he must be out for lunch.   You may borrow the book so long as you keep it clean.   So far as I know（据我所知）, he will be away for three months.   You can go swimming  unless  you go too far away from the river bank. If he had come a few minutes earlier, he could have seen her  ★★练一练★★ 根据中文提示，完成句子。 1. 如果你参加聚会，你将会过得很开心。If you ________ the party, you __________. 2. 如果明天下雨，我们将不去野餐。  If it __________ tomorrow, we ___________. 3. 如果你经常听英文歌，你将会喜欢英语的。 If you often ________, you _________________. 一. 选择填空。 （    ）1.

(stop)  3、I hope he               (come) back in a week.  4、It             (rain) hard when I got to the factory this morning.  5、The old man told the children      (not walk) in the rice fields.  6、He told me he               (help) her with her maths the next evening.  7、She said they              (know) each other for quite some time.  8、If it       (not rain) tomorrow, we      (visit) the Pople’s Museum.  9、John            (write) something when I          (go) to see him. 10、Our teacher told us that light         (travel) much faster thansound.  11、When I got to the cinema, the film               (begin)  12、Mike asked me if we         (ask) any questions the next class.  13、Will you come and stay with us for a while when you               (finish) doing your homework? 14、Comrade Wang didn’t know if there   (be) on English evening that day.  15、Please tell me if she             (come) again next time. 二，单项选择 1. ____ we gave him something to eat, he would save it up for his little sister.　            A.
