地点状语从句：由 where, wherever, anywhere, everywhere等引导。原因状语从句：由 because, since, as, nw that, seeing that, cnsidering that, in that等引导。目的状语从句：由 s, s that, in case, in rder that, fr fear (that)等引导。结果状语从句：由 s (that), s ... that, such ... that, with the result that等引导。
条件状语从句：由 if, unless, s / as lng as, nly if, prvided, n cnditin that, in case, suppse / suppsing (that)等引导。让步状语从句：由 althugh, thugh, even if / thugh, as, whether ... r，“疑问词+ ever”构成的复合词，“n matter +疑问词”等引导。方式状语从句：由 as, like, as if / thugh, the way等引导。比较状语从句：由than或as引导。
二、常用关联词注意事项1. when(1) when引导时间状语从句时，从句的动作既可与主句的动作同时发生，也可先后发生。如：When he lked back, the wman had disappeared.Dn't get excited when yu talk.(2) when还可引导条件状语从句，意为“如果”。如：N ne can make a dress when they haven't learned hw.
2. while(1) while引导时间状语从句时，从句的谓语一般是延续性动词（如wrk, stay, wait, live等）。如：While yu are srting yur things upstairs, I'll pack my bks.(2) while 引导让步状语从句时，相当于 althugh / thugh。while和althugh引导的让步状语从句不用倒装语序，thugh 引导的让步状语从句可以倒装也可以不倒装。如：While / Althugh / Thugh I admit that the prblems are difficult, I dn't agree that they cannt be slved.Happy thugh the little girl is, she will feel hmesick at the beginning.
3. until和till(1) until和till都表示“直到”，常可互换，但till一般不用于句首。如：He determined t stay at the ffice till / until his year was up.Until I was 21, I never missed attending night schl fur nights a week.(2) until / till从句与肯定的主句连用时，主句的谓语动词一般是延续性动词，表示主句的动作一直持续到until / till所表示的时间为止。如：Julie stayed up till / until eleven 'clck last night.
(3) until / till从句与否定的主句连用时，主句的谓语动词是非延续性动词，表示“直到……才”，即主句的动作到 until / till 所表示的时间才开始。如：I cannt cmment further until / till I have all the infrmatin.(4) nt until后跟从句位于句首时，主句需部分倒装。如：Nt until the war was ver was Einstein able t return t his hmeland.
4. as(1) as引导时间状语从句时，表示“当……时；随着”。如：A lk f surprise came int Allisn's eyes as she read the message.As I knew him better, I discvered that my impressins had been right.(2) as引导原因状语从句时，一般放在句首，表示十分明显的原因或是已知的事实。如：As it was getting late, I decided t bk int a htel.
(3) as引导让步状语从句时，通常用倒装结构。详情如下：a. “形容词+ as +主语+系动词”或“副词+ as +主语+实义动词”。如：Tired as they were, they sat up late.Fast as yu read, yu can't finish the bk in tw days.b. 名词+ as +主语+系动词(句首的名词前多不带冠词)。如:Teenager as he is, he has established his wn cmpany.
(4) as引导方式状语从句时，意为“如，像，按照”。如：I want yu t tell my friend yur interesting experience exactly as yu have tld it t me.(5) as引导比较状语从句时，常用于as ... as ... 和nt s / as ... as ... 结构中。如：I never went thrugh a final exam that was as difficult as that ne.There was n bvius reasn why this culd nt be as gd a film as the riginal.
5. n sner ... than和hardly ... when意为“一……就……”，引导时间状语时，主句一般用过去完成时，从句用一般过去时。注意：n sner, hardly 位于句首时，主句的主谓语要部分倒装。如：Mrs Smith had n sner left the rm than they began t talk abut her.N sner had Mrs Smith left the rm than they began t talk abut her.The star had hardly arrived in Rme when he was surrunded by reprters.Hardly had the star arrived in Rme when he was surrunded by reprters.
6. s ... that和such ... that(1) s ... that 常用于以下结构：①s + adj. / adv. + that 从句；②s + adj. + a(n) +可数名词单数形式+ that从句；③s + many / much / few / little + n. + that从句。如：He was s weak that he culd hardly stand up.There was s much smke that they culdn't see acrss the hallway.Everything happened s quickly that I hadn't time t think.
(2) such ... that 常用于以下结构：①such + a(n) + adj. +可数名词单数形式+ that 从句；②such + adj.+可数名词复数形式+ that 从句；③such + adj. +不可数名词+ that从句。如：He was in such a hurry that he almst pushed me ver n the stairs.They are such lvely twins that everybdy likes them very much.It is such cld weather that I can see n ne utside thrugh the windw.

7. “疑问词+ ever”构成的复合词既可引导状语从句，又可引导名词性从句，但“n matter +疑问词”只可引导让步状语从句。如：Whichever (= N matter which) bk yu brrw, yu must return it in a week.Whatever (= N matter what) happens, yu knw that I'll stand by yu.Whever uprted that tree ught t be ashamed f themselves.(此句中的Whever不可用N matter wh替换)
