典型例题分析： Nobody knows if it ________ tomorrow. A. rains B. will rain C. rained 分析：if 分析：if 既可引导宾语从句又可引导状语从句。此题中 判断if 判断if 引导的是宾语从句还是状语从句是解题的关键。 故正确选项为：B 故正确选项为：B。 3. 由“祈使句 + or + 陈述句” 或 “祈使句 + and 陈述句” + 陈述句”的两个句式都可以转化为由if 引导的条件 陈述句”的两个句式都可以转化为由if 状语从句。 Hurry up or you will be late. = If you don't hurry up, you will be late. Study hard and you will pass the exam.= If you study hard, you will pass the exam.
1. when引导的从句 when引导的从句 有时主句的动作和从句的动作同时发生，有时主句的动作 在前，从句的动作在后。如果主句用一般将来时，则从句就要 用一般现在时。 Tom will go to see her when he has time. It was raining when I left the hospital. The film had already began when I got to the cinema. 2. 由while 引导的从句 表示正在进行某一动作时另一动作发生了；还可以表示某 个动作还在进行的同时，另一个动作也在进行之中。例如： While he was reading, the telephone rang. While we were boating on the lake, we saw a fish jump out of the water. While my sister was watching TV, I was writing. While Dad was washing his car, Mum was cooking.
（3）当主句为一般将来时时，until引导的从句用一般现 ）当主句为一般将来时时，until引导的从句用一般现 在时代替一般将来时。例如： Please don't get off the bus until it stops.

The students won't come into the classroom until the teachers finish their work. = The students will come into the classroom when the teacher finish their work.
（三）条件状语从句 1. 引导条件状语从句的连接词有if, unless。如果主 引导条件状语从句的连接词有if, unless。如果主 句用一般将来时，从句应用一般现在时。例如： She will pass the exam if she works harder. If you do well in maths, you can learn other subjects well. 2. 注意判定if 引导的从句是宾语从句还是状语从句。 注意判定if 在英语里，if 在英语里，if 既能引导宾语从句又能引导状语从句。 这要看主句中的谓语动词是及物动词还是不及物动词。 例如： Could you tell me if it fine tomorrow. 这句话的主句谓语动词是tell, 及物动词，所以后面if 这句话的主句谓语动词是tell, 及物动词，所以后面if 引导的从句是宾语从句。 I won't go if it isn't fine tomorrow. 这句话的主句谓语动词是go, 这句话的主句谓语动词是go, 不及物动词，所以后面 if 引导的从句是状语从句。
