答案:
一、
1.When (解析:when 引导时间状语从句,既可指短暂动作也可指延续动作)
2.unless (解析:unless=if...not,意为 “除非”)
3.since (解析:since 引导时间状语从句,主句通常用现在完成时)
4.before (解析:before 意为 “在…… 之前”)
5.so that (解析:so that 引导目的状语从句,意为 “为了”)
6.as soon as (解析:一…… 就……,遵循 “主将从现”)
7.or (解析:or 表示 “否则”,连接并列句)
8.until (解析:not...until... 直到…… 才……)
二、
1.A (解析:if 引导条件状语从句,遵循 “主将从现”,从句用一般现在时)
2.A (解析:as soon as 引导时间状语从句,遵循 “主将从现”)
3.B (解析:when 引导时间状语从句,此处 get home 是短暂动作,while 通常接延续性动词)
4.B (解析:or 表示 “否则”,符合句意逻辑)
5.C (解析:yet 用于否定句或疑问句中,表示 “然而、但是”,语气比 but 强)
三、
1.No matter who
2.As long
3.did...until (解析:主句动作未发生,从句动作已发生,用 not...until...)
4.Now that
5.so...that
备考锦囊:
1.死磕 “主将从现”: 只要看到时间(when, as soon as)或条件(if, unless)引导的从句,只要主句是将来时,从句必须用一般现在时。
2.区分 while 和 when: while 后面通常接进行时(was/were doing);when 后面可以是进行时,也可以是一般过去时(短暂动词)。
3.让步状语从句别混淆: 记住 no matter + 疑问词 和 疑问词 + ever 的用法(如 no matter what = whatever)。
