1、状语从句考点概览:1. when , while , as引导时间状语从句的区别；由when, while, as 引导的时间状语从句when引导的从句的谓语动词可以是延续性的动词，又可以是瞬间动词。并且when有时表示就在那时”。例如：When she came in, I stopped eating.她进来时，我停止吃饭。（瞬间动词）When I lived in the coun tryside, I used to carry some water for him.当我住在农村时，我常常为他担水。（延续性的动词）We were about to leave whe n he came

2、 in.我们就要离开，就在那时他进来了。（瞬间动词）While引导的从句的谓语动词必须是延续性的，并强调主句和从句的动作同时发生（或者相对应）。并且 while有时还可以表示对比。例如：While my wife was readi ng the n ewspaper, I was watch ing TV. （was readi ng是延续性的动词，was reading 和was watching 同时发生）I like playi ng football while you like playi ng basketball.我喜欢踢足球，而你喜欢打篮球。（对比）As表示一边一边”，as引

3、导的动作是延续性的动作，一般用于主句和从句动作同 时发生；as也可以强调 一先一后。例如：We always sing as we walk. 我们总是边走边唱。（as表示一边一边”）As we were goi ng out, it began to snow.当我们出门时，开始下雪了。（as强调句中两个动作紧接着先后发生，而不强调开始下雪的特定时间）as whe n while 的辨析as when while 都表示主、从句动作同时发生，三者差异如下：表示一边一边的意思as1、强调两个动作同时进行，并表示对比时2、用于发生时间较短时whe n1、 还可以表示从句动词的动作在主句动词的动作

4、”之前或之后发生。2、when=and then; at that moment （ 正在那个时候 ）while1、用于时间较长时2、强调两个动作同时进行，并表示对比时有时这三个连词可以互换，有时不可以。It was raining hard when （as） I got there.我到那里时，正在下大雨。 （动作同时发生，when可换为as,但不能换为while，因 为get是点动词.）When I had read the article, he called me.我看完这篇文章之后，她给我打了电话。（从句动作发生在主句之前，注意时态表达，只能用when ）When I got to

5、 the cin ema, the film had begu n.（当）我到了电影院时，电影已经开演了。（从句的动作发生在主句之后，只能用whe n,并要注意时态）He was about to leave, whe n the teleph one rang.他正要离开，忽然电话响了。（此时不能放在句首。主句动词一般表达正在”即将”）while, as不能代替She thought I was talk ing about her daughter, while, in fact, I was talk ing about my daughter.她以为我在谈她女儿，然而，实际上在谈论我女

6、儿。（表转折，对比，when, as都不能代替它）While the alie n was buying a souve nir, the girl called the police.外国人买纪念品时，那女孩给警察打了电话。（表示主句，从句的动作同时发生，while后引导的状语从句的动词必须是延续动词不能是点动词，因为它表示较长时间）Mother was worried because little Alice was ill, especially as （whe n/ while） fatherwas away.妈妈担心，因为小爱丽丝病了，特别是他父亲不在家的时候。（此时as ,when

7、, while可通用）2. 名词词组 the minute ， the moment ， the first time ， each time ， any time 等用作连词，引导时间状语；the minute ，the mome nt一就 the first time + 一般过去 any time:任何the mi nute多指时间点翻译成的时候不翻译成的瞬间，的那一刻the mome nt多翻译成的那一刻，的瞬间as soon as多翻译成一就当就3.before，和since引导时间状语从句的用法以及常见的几个句型ItffisWill beHas beenbeforesincebef

9、以互换 （till 一般不放句首），但是在强调句型中多用 until。 并且要注意的是：如果主句中的谓语动词是瞬时动词，必须用否定形式； 如果主句中的谓语动词是 延续性动词，用肯定或否定形式都可以，但表达的意思不同。例如:I did nt go to bed un til （till） my father came back. 直到我父亲回来我才上床睡觉。It was not un til the meeti ng was over that he bega n to teach me En glish.直至 U散会之后他才开始教我英语。I worked un til he came back

10、.我工作到他回来为止。I did nt work un til he came back.他回来我这才开始工作。Please wait un til I arrived. 在我到达之前请等我。till从句不可以置于句首，只有un til从句可以放在句首。notun til放在句首时主句要倒装。5. although , though , as以及even if , even though引导让步状语从句的用法 ；although不能though那样用作副词，放在句首表示强调时要用even though.6. 结果状语从句中“ so一 that 与“ suchthat 的区别；such是形容词，

(pl.) so + adj. + n.(不可数) so foolishso nice a flowerso many/ few flowers so much/ little mon ey.so many peopleso many 已成固定搭配, 性的，只能用such搭配 之间的转换。such + a(n) + n.such + n. (pl.)s

12、uch +n. (pl.)such +n.(不可数)such a foolsuch a nice flowersuch nice flowerssuch rapid progresssuch a lot of peoplesothat与suchthat之间的转换即为a lot of虽相当于 many，但a lot of为名词 so 与 such7. 条件状语从句 uni ess ， providi ng/provided ， suppose/suppos ing 等弓丨导词的 用法；用条件状语从句时要注意时态的正确使用，当主句是将来时的时候，从句要用一般现在时.He will not leav
