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，一般要用动词一般目前时态表达未来时，用一般过去时表达过去未来式。时间状语从句常见连词有： 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，表达“当……时候”.
【考例】一Mum，____shall we have lunch?
——We will have it when your dad__________. [07连云港市]
A when；returns B where returns C．where；will return D．when；will return
[答案]A．[解析] 答语中when引导了一种时间状语从句，主句用了一般未来时态，因此从句用一般目前时态，可见对的答案在A和B之中。既然答语用了时间状语来回复，可见问句问询也一定是时间，从而确定对的答案为A。
2. before 使用措施：before本意为“在……之前”，根据详细语境还可理解为“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 me 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)所有可以引导时间状语从句，as soon as一……就．before在……之前；after在……后来；until直到……才。分析句子可以看出句意为“在你走之前把你电子邮件地址给我好吗
2．until 和till 使用措施：和肯定式主句连用，主句谓语必需是延续性动词，till/ until表达“……直到……”；与否认式主句连用，且主句谓语是非延缓性动词时，till/ until表达“直到……才……”。其强调句型为“not…until” ，在句首时要采用倒装形式。如：
【考例】一Hurry up．The bus is coming．
——Oh。no．We mustn't cross the street ____the traffic lights are green．[福州市]
A． after B since C while D．until
[答案]D ．[解析]本题应从句意人手。until常见于否认句中，构成"not…until"构造，意为“直到……才……”，该句意为“直到交通灯变绿，我们才能穿过马路”。
The kids didn't start to fly kites in the playground _________the rain stopped. [成都市]
A. if B. until C. whenever
[答案]B．[解析] not…until…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. Don't get on it _________it has stopped. [安徽省]
A. until B. after C. since D. when
A．[解析]句中有don't，可想not．．．until为固定构造，意为“直到……才……”。

二、条件状语从句
引导条件状语从句从属连词有if ,unless(=if …not假如不……，除非)，as/so long as ,while(=as long as 只要)，supposing(that),provided/providing(that),in case(假使)，on condition that(在……条件下)等。如：
【考例】__you go to bed earlier, you won't feel tired in the mornings．[沈阳市]
A． Unless B Because C．If D．When
[答案]C ．[解析]考察if引导条件状语从句。“假如你早一点上床睡觉，那么你在上午就不会感到累。”
You won't pass your exams ___________ you work harder. [广东省]
A. when B. if C. unless D. after
[答案]C ．[解析]when，after一引导是时间状语从句，不合题意；if，unless引导是条件状语从句，If不合句意，“除非你愈加努力地学习，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从属连词有：though，although，even if／though， while(虽然、尽管)，for a11(that)(尽管)whether．．．or(不管／不管……还是……))和“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 . （ 江西省南昌）
A．when B．if C．because D．though
[答案]: D
[命题立意]：本题考察从属连词引导让步状语从句使用措施。
[试题解析]：根据上句：我们继续工作吗？是，尽管我想休息会。
Edison never gave up, he failed many times. ( 四川)
A．and B．though C．or
[答案]: B
[命题立意]：本题考察从属连词引导让步状语从句使用措施。
[试题解析]：根据题意：虽然爱迪生失败多次，她也决不放弃。though用来引导让步状语从句。故选B。

四、目的状语从句
引导目的状语从句从属连词有 so that , in order that (为了，以便)；in case(以防，以免)，lest(省得，以防)，for fear that(以免，惟恐)等。从句中一般具有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 0lympic Games．
一I'm sure they will．[宜昌市]
A．because of B so that C．even though D．as if
[答案]B．[解析] 本题也应从句意人手。越来越多人学习英语，“为是”能更多愈加好地为奥运服务。so that引导一种目的状语从句。

五、成果状语从句
【考例】The camera is expensive I can’t afford it. ( 辽宁本溪)
A. so, that B. such, that C. so, as to D. enough, that
[答案]: A
[命题立意]：本题考察从属连词引导成果状语从句使用措施。
[试题解析]：根据题意：这摄影机太贵以致我买不起。expensive为形容词,so…that…句中要用形容词或副词；such…that…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】
状语从句分类。
1. 时间状语从句使用措施要点。
（1）as、when、while使用措施一览表。
类别
作 用
例 句
as
as表达“当……时候”，往往和when/ while通用，但它着重强调主句和从句动作或事情同步或几乎同步发生。
She came up as I was cooking.(同步)
The runners started as the gun went off.(几乎同步)
when
(at or during the time that )既可以表达在某一点时候，又可表达在某一段时间内，主句和从句动作或事情可以同步发生也可以前后发生。
It was raining when we arrived.(指时间点)
When we were at school, we went to the library every day.(在一段时间内)
while
while意思是“当……时候”或“在某一段时间里”。主句中动作或事情在从句中动作或事情进展过程中发生，从句中动词一般要用延续性动词。在when表达a period of time时，两者可以互换。
Please don’t talk so loud while others are working.
He fell asleep while/when reading. Strike while the iron is hot.(用as或when不可，这里while意思是“趁……”)
一般从句所有必需有引导词，引导时间状语从句词有 when, before, after, until, as soon as, while 等，详细使用措施如下：
1. when 意为“当……时”，引导时间状语从句，表达主句动作和从句动作同步或前后发生。例如：
I feel very happy when you come to see me. 你（们）来看我时，我感到很快乐。
When you are crossing the street, you must be careful. 你（们）过街道时，一定要小心。
when引导时间状语从句，when从句可以用延续性动词，也可以用点动词。例如：
He was working at the table when I went in. 当我进去时候，她正在桌旁工作。
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，我将去看望我好友。
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，表达一种动词正在进行时候，忽然间发生了此外一件事。
I was fishing by the river , 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，忽然灯所有熄灭了。
2. before 意为“在……之前”，引导时间状语从句时，表达主句动作发生在从句动作之前。例如：
We cleaned the classroom before we left school yesterday.昨天离开学校之前，我们打扫了教室。
He had been a cook before he went to college . 她上大学前曾当过厨师。
after 意为“在……后来”，引导时间状语从句时，表达主句动作发生在从句动作后来。例如：
After you use plastic bags, you mustn't throw them about. 你（们）用过了塑料袋后来，不准到处乱扔。
He called me after he had finished his work. 她在工作完后来给我打了个 。
注：若主句和从句两个动作发生前后次序十分靠近，那么也可以不用完毕时态，例如上面第二句可改成：He called me after he finished his work.
3. since引导时间状语从句，译为“自从……”，主句常见目前完毕时，从句常见一般过去时。例如：
We have made many dumplings since we began to cook. 自从我们开始做饭起，我们已经包了诸多饺子了。
We haven't seen each other since we parted . 我们自从分手后来一直没见过面。
注：常见句型：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. 自从她大学毕业已经有六年时间了。
4. until 意为“直到……时”，引导时间状语从句时，表达主句动作发生在从句动作之前。当主句谓语动词是持续性动词时，主句常见肯定形式；当主句谓语动词是非持续性动词时，从句常见否认形式, not... until... 意为“直到……才……”，这时until可以用before 来替代。例如：
I'll stay here until you come back. 我会呆在这里，直到你回来。(stay表达动作可以持续)
He didn't go to bed until he finished his homework.她直到做完作业才睡觉。(go to bed 表达动作不能持续)
5. as soon as 意为“一……就……”，表达从句动作一发生，主句动作立即就发生。例如：
I'll tell him about it as soon as he comes back.她一回来我就告诉她这件事。
6. while引导时间状语从句，常译为“和……同步，在……期间”，while从句中常见延续性动词或表达状态词。例如：
They rushed in while we were discussing problems. 当我们正在讨论问题时，她们冲了进来。
Father was cleaning the car while I was playing computer games. 当我正在打电子游戏时，父亲正在清洗汽车。
注：while也可以作并列连词，表转折关系，相称于but，译为“然而”。 例如：
I like listening to music, while my brother likes doing sports. 我爱慕听音乐，而我兄弟爱好运动。
7. till和until引导时间状语从句，译为“直到……为止”，not … till / until引导时间状语从句，译为“直到……才”。前者强调主句动作结束，用延续性动词，后者强调主句动作开始，用点动词。例如：
I will wait for my friend until / till he comes. 我要一直等到我好友来。
We won't start our discussion until / till he comes. 我们要等到她来了，再开始我们讨论。
2. 条件状语从句使用措施要点。
我们关键看一下由if引导条件状语从句。if 意为“假如”，引导条件状语从句时，表达假如有从句动作发生就(不)会有主句动作发生。例如：
If it doesn't rain tomorrow, we will go there by bike.假如明天不下雨，我们就骑自行车去那里。
If I get there early, I can see the doctor quickly.假如我早早地到那里，我就可以快点看病。
3. 地点状语从句使用措施要点。常见where（哪里）和wherever（不管哪里）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. 我们要到祖国最需要地方去。
4. 原因状语从句使用措施要点。
　　常见引导连词有because, as和since。三者辨别是：在答复问题时候，使用because；对于显而易见原因，常见as或since；as和since从句常放在主句之前，而because从句常放在主句后来。eg.
Why did you go?  I went because Tom told me to go. 你为何去？那是由于汤姆叫我去。
He was angry not because we were late but because we made a noise. 她很生气不是由于我们来迟了，而是由于我们弄出了声音。
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, you'd better not go to work. 既然你感觉不舒适，你最佳不要去上班了。
5. 目的状语从句使用措施要点。
　　常见引导连词有so that, that和in order that译为：以便，为了，目的是。例如：
Please speak more slowly so that we can make full notes. 请讲慢一点，以便我们能作详细笔记。
I shall write down your address that I may not forget. 我要把你地址记下来，以免忘掉。
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，以便她能立即收到。
注：目的状语从句可以用动词不定式来替代做目的状语eg.
We work harder than usual finish it in a week.  我们比平常加倍努力工作以在一周内完毕工作。

三：主句和从句时态一致问题。
在时间状语从句和条件状语从句中，主句和从句之间时态一致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未来时，那么从句用一般目前时表达一般未来时。例如：
Be careful when you cross the road. 过马路时要小心。
Put up your hand if you have any questions to ask. 假如你们有问题要问话，请举手。
The traffic must stop when the lights are red. 红灯亮时，车辆必需停下。
2. 若主从句谓语动词所有是陈说过去，那么主从句所有可以用一般过去时。例如：
She could sing when she was four years old. 她四岁时候就会唱歌。
