状语从句有多种, 时间、条件、原因、结果最常用。
时间从句常用when, because用来表原因。
状语从句条件表, if前面来引导。
结果状语也不难, 请把so. . . that/such. . . that来分辨。【温馨提示】
1. 在时间状语从句和条件状语从句中, 如果主句是一般将来时, 从句要用一般现在时。例如:
We are going to play football if it doesn’t rain this afternoon. 2. so. . . that与such. . . that的区别
它们词义相同, 但结构不同, 请对比下面的句型结构: 例如:
This is such a good film that every one wants to see it.
This is so good a film that every one wants to see it.
这是一部很好的影片, 大家都想看。3. because(因为), so(所以, 因此)不能同时出现在一个句子中。因为because是从属连词, 而so是并列连词, 用来连接并列句。例如: 由于没赶上公共汽车, 所以她上学迟到了。
误: Because she missed the bus, so she was late for school.
正: Because she missed the bus, she was late for school.
正: She missed the bus, so she was late for school.
