答案 1.after [引导时间状语从句。] 2.until [“直到”，主句为肯定句时，谓语动词用延续性动词；主句为否定句时，谓语用短暂性动词。] 3.unless [“如果不，除非”，引导条件状语从句，此外还有：once(一旦)，in case(万一)，when(既然)……] 4.as [as引导让步状语从句，此外常考的还有：although，though，while“尽管”。] 5.because [引导原因状语从句，此外还有：since，as，now that，seeing(that)...]

【正】 In such dry weather，the flowers will have to be watered if they are to survive.
解析 if 从句中表示将来不能用will，be going to 等，但可以使用if sb/sth is to do sth 结构。 2.【误】 You will be late unless you will leave immediately.
【正】 You will be late unless you leave immediately.
解析 在时间、条件、让步、方式等状语从句中，常用一般现在时表示将来时。
3.【误】 Mum would not let him buy it，as if he had enough money!
【正】 Mum would not let him buy it，even if he had enough money!
解析 从前后两个句子之间的逻辑关系可知，应用even if。even if 即使；as if 好像。
4.【误】 Not until I began to work I realized how much time I had wasted.
【正】 Not until I began to work did I realize how much time I had wasted.
解析 not until...置于句首时，主句应使用部分倒装结构。
5.【误】 I won't agree with no matter what you may say.
【正】 I won't agree with whatever you may say.
【正】 Whatever / No matter what you may say，I won't agree.
解析 whatever 引导的从句作 agree with 的宾语，即作宾语从句，whatever 不能与 no matter what 替换。而引导让步状语从句时可替换。
