While he was do

2、ing his homework, the telephone rang. As he walked along the lake, he sang happily. He had learned a little Chinese before he came to China. After he finished middle school, he went to work in a factory. (2)在时间状语从句里，通常不用将来时态，用现在时态表示将来的动作或状态。例如：I ll ring you up as soon as I get to New York.I will tel

3、l him everything when he comes back. He won t believe it until he sees it with his own eyes.(3)在带有 till 或 until 引导的时间状语从句的主从复合句里，如果主句用肯定式，其含义是 “ 一直到 时” ，谓语动词只能用延续性动词。如果主句用否定式，其含义是“ 直到 才” , “在 以前不 ” , 谓语动词可用瞬间动词。例如：The young man read till the light went out. Let s wait until the rain stops.We won t s

4、tart until Bob comes.Don t get off until the bus stops.2. 条件状语从句(1)条件状语从句通常由if, unless 引导。例如：What shall we do if it snows tomorrow? Don t leave the building unless I tell you to.(2)在条件状语从句里，谓语动词通常用现在时态表示将来的动作或状态。例如：I ll help you with your English if am free tomorrow.He wo n t be late unless he is il

5、l.(3) “祈使句+ and (or)+ 陈述句 ” 在意思上相当于一个带有条件状语从句的复合句。例如：初高中衔接暑期英语语法讲义专项练习含答案解析2 Hurry up, or you ll be la te. =If you don t hurry up, you ll be late.Study hard and you will pass the exam. =If you study hard, you will pass the exam. 3. 原因状语从句(1)原因状语从句通常由because, since, as引导。例如：He didn t come to school b

6、ecause he was ill.As it is raining, we shall not go the zoo. Since you can t answer the question, I ll ask someone else.(2)because 表示直接原因，语气最强。Because 引导的原因状语从句多放在主句之后。回答由 why 提出的问题，只能用because。As 和 since 语气较弱，一般用来表示明显的原因。由as和 since 引导的原因状语从居多放在句首。例如：- Why aren t going there?- Because I don t want to

7、.As he has no car, he can t get there easily.Since we have nomoney, we can t buy it.(3)because和 so 不能同用在一个句子里。4. 结果状语从句(1)结果状语从句由so that, such that, so that引导。例如：He is so poor that he can t buy a bike for his son.She is such a good teacher that everybody likes her. My pencil fell under the desk, so

8、that I couldn t see it.(2)so that语 such.that 可以互换。例如：在由 so.that 引导的结果状语从句中，so是副词，与形容词连用。 其结构是 : “.so + 形容词（副词）+ that + 从句 ” 。例如：He was so glad that he couldn t say a word.The hall is so big that it can hold 2,000 people. Mother lives so far away that we hardly ever see her. 在由 suchthat 引导的结果状语从句中，su

9、ch 是形容词，它修饰的可以是单数或复数可数名词，也可以是不可数名词；名词前面可以带形容词，也可不带。如果是单数可数名词，前面需加不定冠词a或 an。例如：It was such a hot day that nobody wanted to d o anything. He had such long arms that he could almost touch the ceiling. He made such rapid progress that he did very well in the mid-term. 初高中衔接暑期英语语法讲义专项练习含答案解析3 有时上述两种结构是可以

10、互换的。例如：It was such a wonderful film that all of us wanted to see it again. =The film was so wonderful that all of us wanted to see it again. It is such an important match that nobody wants to missit. =The match is so important that nobody wants to miss it. (3)如果名词前由many, much, little, few 等词修饰时，只能用s

11、o, 不用 such。例如：Soon there were so many deer that they ate up all the wild roses. He has so little time that he can t go to the cinema with you.5. 比较状语从句比较状语从句通常由asas, 比较级+ than 等连词引导。例如：Tom runs faster than John does.

(2)so that 既可引导目的状语从句，又可引导结果状语从句。区别这两种从句的办法有两个： 1)目的状语从句里往往带有情态动词can, could, may, might 等。2)从意思上看，目的状语从句往往表示的目的很明确。例如：Spea

13、k clearly so that they may understand you. (目的状语从句) Jack is badly ill so that he has to rest. (结果状语从句 ) 7. 让步状语从句(1)让步状语从句通常由although, though 等连词引导。例如：Though he is young, he knows a lot. Although I am tired, I must go on working. (2)although(though) 不能用在同一个句子中。例如：我们不能说： Though it was raining hard, b

14、ut he still went out. 应该说： Though it was raining hard, he still went out.或 It was raining hard, but he still went out. 8. 地点状语从句地点状语从句常常由where 来引导。例如：Go where you like.
