1、中考英语语法:状语从句一、时间状语从句在时间状语从句中，通常要用动词的一般如今时态表示将来时，用一般过去时表示过去将来式。时间状语从句常用连词有： when, as, while, whenever, after, before, till (until), since, once, as soon as (或the moment ), by the time, no sooner than, hardly (scarcely) when, every time等引导。1 考察when, while, as引导，表示“当时候”.【考例】一Mum，_shall we have lunch We

2、will have it when your dad_. 07连云港市A when；returns B where returns Cwhere；will return Dwhen；will return答案A解析 答语中when引导了一个时间状语从句，主句用了一般将来时态，所以从句用一般如今时态，可见正确答案在A及B之中。既然答语用了时间状语来答复，可见问句询问的也确定是时间，从而确定正确答案为A。2. before 的用法：before的本意为“在之前”，根据具体语境还可理解为“还没来得及/还没有就，趁着还没就，不知不觉就，才”等。如：【考例】Could you please give m

3、e your e-mail address _you go 昆明市A. as soon as B. before C. after D. until答案B解析这四个词(组)都可以引导时间状语从句，as soon as一就before在之前；after在之后；until直到才。分析句子可以看出句意为“在你走之前把你的电子邮件地址给我好吗”2until 和till 的用法：及确定式的主句连用，主句谓语必需是持续性动词，till/ until表示“直到”；及否认式的主句连用，且主句谓语是非延缓性动词时，till/ until表示“直到才”。其强调句型为“notuntil” ，位于句首时要采纳倒装形式

4、。如：【考例】一Hurry upThe bus is comingOh。noWe mustnt cross the street _the traffic lights are green福州市A after B since C while Duntil 答案D 解析本题应从句意人手。until常用于否认句中，构成notuntil构造，意为“直到才”，该句意为“直到交通灯变绿，我们才能穿过公路”。The kids didnt start to fly kites in the playground _the rain stopped. 成都市A. if B. until C. whenever

5、答案B解析 notuntil直到才。“直到雨停孩子们才可以去操场放风筝”，-Look! Here comes our school bus. -No hurry. Dont get on it _it has stopped. 安徽省A. until B. after C. since D. whenA解析句中有dont，可想notuntil为固定构造，意为“直到才”。二、条件状语从句引导条件状语从句的附属连词有if ,unless(=if not假设不，除非)，as/so long as ,while(=as long as 只要)，supposing(that),provided/prov

6、iding(that),in case(假使)，on condition that(在的条件下)等。如：【考例】_you go to bed earlier, you wont feel tired in the mornings沈阳市A Unless B Because CIf DWhen答案C 解析考察if引导的条件状语从句。“假设你早一点上床睡觉，那么你在上午就不会感到累。”You wont pass your exams _ you work harder. 广东省 A. when B. if C. unless D. after答案C 解析when，after一引导的是时间状语从句，

7、不合题意；if，unless引导的是条件状语从句，If不合句意，“除非你更加努力地学习，否则，你不会通过考试”。故用unless。三、让步状语从句用来引导让步地点状语从句的附属连词有：though，although，even ifthough， while(虽然、尽管)，for a11(that)(尽管)whetheror(不管不管还是)以及“疑问词+ever（whatever，wherever，whoever，however，）”和 “no matter +疑问词”等。 【考例】Shall we go on working Yes , I prefer to have a rest . （2

(2004四川)AandBthoughCor答案: B命题立意：本题考察附属连词引导让步状语从句的用法。试题解析：根据题意：即使爱迪生失败屡次，他也决不放弃。though用来引导让步状语从句。故选B。四、目的状语从句引导目的状语从句的附属连词有 so that , in order that (为了，以便)；in case

9、(以防，以免)，lest(免得，以防)，for fear that(以免，惟恐)等。从句中一般含有can , could, may,might ,will, would等情态动词。如：【考例】一More and more people in Beijing are learning English _they can better serve the 2008 0lympic Games一Im sure they will宜昌市Abecause of B so that Ceven though Das if答案B解析 本题也应从句意人手。越来越多的人学习英语，“为的是”能更多更好地为奥运效劳

(2004辽宁本溪)A. so, that B. such, that C. so, as to D. enough, that答案: A命题立意：本题考察附属连词引导结果状语从句的用法。试题解析：根据题意：这照相机太贵以致我买不起。expensive为形容词,sothat句中要用形容词或副词；suchthat要用形容词修饰名词。其他两项不能引起从句。故选A。【语法回忆】状语从句的分类。1. 时间状语从句用法要点。（1）as、when、while用法

11、一览表。类别作 用例 句asas表示“当的时候”，往往和when/ while通用，但它着重强调主句及从句的动作或事情同时或几乎同时发生。She came up as I was cooking.(同时)The runners started as the gun went off.(几乎同时)when(at or during the time that )既可以表示在某一点的时候，又可表示在某一段时间内，主句及从句的动作或事情可以同时发生也可以先后发生。It was raining when we arrived.(指时间点)When we were at school, we went

12、to the library every day.(在一段时间内)whilewhile意思是“当的时候”或“在某一段时间里”。主句中的动作或事情在从句中的动作或事情的进展过程中发生，从句中的动词一般要用持续性动词。在when表示a period of time时，两者可以互换。Please dont talk so loud while others are working.He fell asleep while/when reading. Strike while the iron is hot.(用as或when不行，这里的while意思是“趁”)但凡从句都必需有引导词，引导时间状语从句

13、的词有 when, before, after, until, as soon as, while 等，具体用法如下：1. when 意为“当时”，引导时间状语从句，表示主句的动作和从句的动作同时或先后发生。例如： I feel very happy when you come to see me. 你（们）来看我时，我感到很兴奋。When you are crossing the street, you must be careful. 你（们）过街道时，确定要当心。when引导的时间状语从句，when的从句可以用持续性动词，也可以用点动词。例如：He was working at the

14、table when I went in. 当我进去的时候，他正在桌旁工作。Someone knocked at the door when I was sleeping. 当我正在睡觉时，有人敲门。I will visit my good friend when I have time. 当我有空儿时，我将去探望我的好友。I worked for a foreign company when I was in Shanghai. 当我在上海时，我为一家外国企业工作。注：when也可以作并列连词，表示一个动词正在进展的时候，突然间发生了另外一件事。I was fishing by the ri

15、ver , when someone called for help. 我正在河边钓鱼，就在那时有人求救。We were working in the chemistry lab, when the lights went out. 我们正在化学试验室工作，突然灯都熄灭了。2. before 意为“在之前”，引导时间状语从句时，表示主句的动作发生在从句的动作之前。例如： We cleaned the classroom before we left school yesterday.昨天分开学校之前，我们清扫了教室。 He had been a cook before he went to c

16、ollege . 他上高校前曾当过厨师。after 意为“在之后”，引导时间状语从句时，表示主句的动作发生在从句的动作之后。例如： After you use plastic bags, you mustnt throw them about. 你（们）用过了塑料袋之后，不准到处乱扔。He called me after he had finished his work. 他在工作完之后给我打了个 。注：若主句和从句两个动作发生的先后依次非常接近，那么也可以不用完成时态，例如上面的第二句可改成：He called me after he finished his work. 3. since引

17、导的时间状语从句，译为“自从”，主句常用如今完成时，从句常用一般过去时。例如：We have made many dumplings since we began to cook. 自从我们开场做饭起，我们已经包了很多饺子了。We havent seen each other since we parted . 我们自从分手以后始终没见过面。注：常用句型：It is +时间段+since从句 译为：自从有多长时间了。例如：It is six years since she graduated from the university. 自从她高校毕业已有六年的时间了。4. until 意为“直到

18、时”，引导时间状语从句时，表示主句的动作发生在从句的动作之前。当主句的谓语动词是持续性动词时，主句常用确定形式；当主句的谓语动词是非持续性动词时，从句常用否认形式, not. until. 意为“直到才”，这时的until可以用before 来交换。例如：Ill stay here until you come back. 我会呆在这里，直到你回来。(stay表示的动作可以持续) He didnt go to bed until he finished his homework.他直到做完作业才睡觉。(go to bed 表示的动作不能持续) 5. as soon as 意为“一就”，表示从句

19、的动作一发生，主句的动作立刻就发生。例如： Ill tell him about it as soon as he comes back.他一回来我就告知他这件事。6. while引导的时间状语从句，常译为“及同时，在期间”，while的从句中常用持续性动词或表示状态的词。例如：They rushed in while we were discussing problems. 当我们正在探讨问题时，他们冲了进来。Father was cleaning the car while I was playing computer games. 当我正在打电子嬉戏时，爸爸正在清洗汽车。注：while也

20、可以作并列连词，表转折的关系，相当于but，译为“然而”。 例如：I like listening to music, while my brother likes doing sports. 我喜爱听音乐，而我的兄弟爱好运动。7. till和until引导的时间状语从句，译为“直到为止”，not till / until引导的时间状语从句，译为“直到才”。前者强调主句动作的完毕，用持续性动词，后者强调主句动作的开场，用点动词。例如：I will wait for my friend until / till he comes. 我要始终等到我挚友来。We wont start our dis

21、cussion until / till he comes. 我们要等到他来了，再开场我们的探讨。2. 条件状语从句用法要点。 我们主要看一下由if引导的条件状语从句。if 意为“假设”，引导条件状语从句时，表示假设有从句的动作发生就(不)会有主句的动作发生。例如： If it doesnt rain tomorrow, we will go there by bike.假设明天不下雨，我们就骑自行车去那里。If I get there early, I can see the doctor quickly.假设我早早地到那里，我就可以快点看病。3. 地点状语从句用法要点。常用where（哪里

22、）和wherever（无论哪里）例如：Where there is a will, there is a way. 有志者，事竟成。We will go wherever the motherland needs us most. 我们要到祖国最须要的地方去。4. 缘由状语从句用法要点。常用的引导连词有because, as和since。三者的区分是：在答复问题的时候，运用because；对于自不待言的缘由，常用as或since；as和since的从句常放在主句之前，而because的从句常放在主句之后。eg.Why did you go I went because Tom told me

23、to go. 你为何去？那是因为汤姆叫我去。He was angry not because we were late but because we made a noise. 他很生气不是因为我们来迟了，而是因为我们弄出了声音。As it was raining hard, we had to be indoors. 由于雨太大，我们只好呆在家里。Since you feel ill, youd better not go to work. 既然你感觉不舒适，你最好不要去上班了。5. 目的状语从句用法要点。常用的引导连词有so that, that和in order that译为：以便，为了

24、，目的是。例如：Please speak more slowly so that we can make full notes. 请讲慢一点，以便我们能作具体笔记。I shall write down your address that I may not forget. 我要把你的地址登记来，以免遗忘。I sent the letter by air mail in order that it might reach him in time. 这封信我以航空信发出，以便他能刚好收到。注：目的状语从句可以用动词不定式来交换做目的状语eg.We work harder than usualfin

25、ish it in a week. 我们比平常加倍努力工作以在一周内完成工作。三：主句及从句时态一样的问题。 在时间状语从句和条件状语从句中，主句和从句之间的时态一样问题一般分下列两种状况： 1. 若主句是祈使句，或主句中有情态动词，或主句中谓语动词是一般将来时，那么从句用一般如今时表示一般将来时。例如： Be careful when you cross the road. 过公路时要当心。Put up your hand if you have any questions to ask. 假设你们有问题要问的话，请举手。The traffic must stop when the ligh

26、ts are red. 红灯亮时，车辆必需停下。2. 若主从句谓语动词都是陈述过去，那么主从句都可以用一般过去时。例如： She could sing when she was four years old. 她四岁的时候就会唱歌。【语法过关】1I was drawing a horse _the teacher came in.
