1、牛津译林九年级上册状语从句练习【知识梳理】状语从句状语从句：用来修饰主句中的动词，副词和形容词的从句叫状语从句。根据其含义状语从句可分为时间状语从句，地点状语从句，条件状语从句，原因状语从句，结果状语从句，比较状语从句，目的状语从句，让步状语从句。一、时间状语从句引导时间状语从句的连词有：while, when, as, as soon as, till, until, notuntil, before, after, since, etc当主句用一般将来时或表示将来含义时，时间状语从句常用一般现在时表示将来。【例句】Ill tell you the news when I come back
2、. She will call me as soon as she arrives in Shanghai.1.在when引导的时间状语从句中，动作可以是表示延续的，也可以是表示瞬间的；while引导的从句中，动作一定是表示延续的.【例句】I was watching TV when Tom came in. Tom came in while I was watching TV.2.as“当.时；一边.一边.”引导的时间状语从句，强调主句的动作与从句的动作同时发生，when与while也有此用法。另外when和as常表示从句动作先于主句动作，有时when还可以表示从句动作在主句动作之后。【例
3、句】As she was dancing, she was singing. Its getting colder and colder as the winter comes.3.before “在.以前”，表示主句的动作发生在从句动作之前；after “在之后”，表示主句的动作发生在从句动作之后。【例句】She was so interested in the book that she had read it for three hours before she realized it. I went to bed after I finished homework.4. until/t
4、ill表示主句动作结束的时间。在肯定句中表示“直到.为止”，主句要用延续性动词。【例句】My mother waited till/until I came back.【注意1】在否定句中，until/till表示“直到.才”，主句通常用瞬间动词。这时until可用before替换。常构成：notuntil结构，有时可用never, nothing代替not.【例句】He didnt leave until/before I came back.【注意2】till 不用于句首 till是指直到某一特定事件发生的时候，而在那个时刻之后，该事情或状况仍将持续。until是指直到某一特定事件发生的时
5、候，而讲话的人在自己心里认为，在那个时刻之后，该事情或该状况将中止（几乎不可能持续）。另外，在固定组合里frommorningtillnight，till/until是不能替换的 5. since，ever since引导的时间状语从句，表示主句动作开始的时间，译为“自.以来”。主句常用一般现在时或现在完成时，从句用一般过去时，常用句型为： It has beensince从句；It is +一段时间+since从句。【例句】Its ten years since I worked in the hospital. He has taught us Maths since he came he
6、re. Where have you been since I saw you last？【注意】对 since 引导的时间状语提问要用how long6.by the time引导的时间状语从句注意时态的变化：在一般情况下，如果从句的谓语动词用一般过去时，主句的谓语动词用过去完成时.【例句】By the time you came back, I had finished this book.7.由each time, every time和whenever引导的时间状语从句【例句】Each time she came to Hainan, she would call on me. Whe
7、never you go, I will follow you! You grow younger every time I see you.8.as soon as表示主句发生的动作发生在从句动作之后，意为“一就”。如果主句是一般将来时，情态动词加动词原形或祈使句时，时间状语从句用一般现在时。【例句】My brother went out as soon as I got home. Ill phone you as soon as I arrive in Tonghua 时间状语从句中的重难点和易错点：until (till) 直到，在用 until 表达时间状语的句子中如果动词是持续性动
8、词，则要用肯定句；【例句】I studied hard until 12 oclock last night. 如果动词是非延续性动词，则要用否定句。【例句】He didnt go to bed until his mother came back由since，for，by，before 来引导的时间状语从句since 引导的时间状语是动作的开始时间【例句】I have studied English since 1990. 而由 by 引导的时间状语通常是动作的结束时间【例句】I had learned 25 English songs by the end of last term.而be
9、fore 则多用于完成时， ago 则多用于一般过去时【例句】He had finished his work before twelve yesterday. I left my hometown two years ago.在状语从句中用一般现在时表示将来。通常主句用一般将来时，从句用一般现在时【例句】If it rains, they wont go to the park on Sunday. 考试中常见的考点有：要学生区别是条件状语从句、时间状语从句还是宾语从句.【例句】I want to know if he will come here tomorrow I want to kn
10、ow if it rains he will come here tomorrow二、条件状语从句 1.条件状语从句通常由if, unless引导。unless在意义上相当于ifnot 表示“除非”“如果不”。由于本身已含有否意义，因此不要在unless后用否定句式。【例句】What shall we do if it snows tomorrow? Dont leave the building unless I tell you to.2.在条件状语从句里，谓语动词通常用一般现在时态表示将来的动作或状态。(即“主将从现”)【例句】Ill help you with your English
11、 if am free tomorrow. He wont be late unless he is ill.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。【例句】Hurry up, or youll be late. =If you dont hurry up, youll be late. Study hard and you will pass the exam. =If you study hard, you will pass the exam.4.用介词with/ without可以把条件状语从句改写成简单句：【例句】If there
12、is no water, the fish may die. = Fish may die without water. If you help me, Ill finish my task on time. = With your help, Ill finish my task on time. 三、原因状语从句 1.原因状语从句通常由because, since, as引导。【例句】He didnt come to school because he was ill. As it is raining, we shall not （不得；不应该）go the zoo. Since you
13、 cant answer the question, Ill 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。【例句】-Why arent going there? -Because I dont want to. As he has no car, he cant get there easily. Since we have no money, we cant buy i
14、t.【注意1】because不能与并列连词so同时在句中使用【例句】She was late for school because she missed the bus. = She missed the bus, so she was late for school.【注意2】because和becouse of 也有明显的区别。because后面要跟从句，而because of 后面要跟名词短语。【例句】He is late for school because it rains heavily. He is late for school because of the heavy rain. 四、结果状语从句 1.结果状语从句由sothat, suchthat引导【例句】He is so poor that he cant buy a bike for his son. She is such a good teacher that everybod
