v 考点归纳
1. 状语从句的类型: 时间状语从句、地点状语从句、原因状语从句、条件状语从句、目的状语从句、结果状语从句、让步状语从句、比较状语从句、方式状语从句
2. 时间状语从句:
⑴ 连接词及固定搭配: when, while, as, since, after, before, until / till, once, each time, every time, any time, whenever, as soon as, the moment, the minute, the instant, hardly / scarcely / barely / rarely … when / before, no sooner … than, just as, directly, immediately, instantly, shortly after, soon after, it won’t be long before, by the time, it’s the first time that, it’s … since, the first time, the last time
⑵ as soon as与hardly … when等结构都能表示“一……就……”，但两者的时态不同；前者一般主从句均为一般时态，表示一般情形遵从主将从现原则；后者一般主句为过去完成时，从句为一般过去时，且在句首引起倒装
⑶ 特殊地，可用the minute, each time, the first time等名词或名词短语充当连接词引导时间状语从句，该类词称为边际从属连词
3. 地点状语从句可由where, wherever引导，前者指特定地点，后者为无特定地点
4. 原因状语从句:
⑴ 可由because, since, now that, as, in that引导，注意for, so, with + n. + 宾补结构
⑵ 现代英语中，because与for都可引导原因状语从句，且都能表示“直接理由”与“间接理由”，如It must be very late, for the streets are quite deserted. (间接理由)
上句中的for实也可替换为because，只是在两者同时存在时，使用for语势较弱，更显出说话人的推断的不确定性，说明说话人的推断略显主观臆断
⑶ 在表述直接理由时，because, since, as从句位置既可在主句前，也可在句尾；而for则只能位于主句后；此外，because可回答why问句，because前可加入诸如simply的修饰语，because从句也可作为强调句的强调部分，这些场合下because不能替换为for；若because也表述的是间接理由，则其位置只能在主句后
5. 条件状语从句的连接词及相关搭配: if, unless (» if … not), on condition that, given that, as / so long as, suppose that, even if, even though, provided that, in case, lest, given that, considering that, since, now that等
6. 目的状语从句可由that, in order that, so that, for the purpose that, in the hope that等作连接词或固定搭配，常与情态动词连用
7. 结果状语从句:
⑴ 连接词及固定搭配: that, so … that, such … that, so that等
⑵ such修饰名词，so修饰形容词或副词，such / so结构类似于what / how的固定结构；当such修饰可数名词单数时可将其与so结构互换；若such修饰不可数名词或可数名词复数时则无法互换
⑶ 当many, few, little, much表多少修饰名词时只能用so；若little不表多少，且修饰可数名词单数时只能用such
8. 让步状语从句:
⑴ although, though, as, while, even if, even though, however, whatever, no matter系列等
2
⑵ though引导的让步状语从句可以倒装(也可不倒装)，作用相当于as (必须倒装)，此时though不能与although替换；though与although都不能与but并存，却能与yet并存；as引导让步状语从句时，倒装形容词、副词及无冠词的名词；只存在even though，而无 *even although；though也可作连接性状语，而although不可，如He said he would come; he didn’t, though.
⑶ -ever系列与no matter系列的区别(见前)
9. 比较状语从句可由than, as... as, not as/so...as, the more....the more引导
10. 方式状语从句可由as, as if, as though引导
