并列复合句与状语从句(3)

时间：2026-01-22

I shall go if he asks me. 如果他请我，我就去。

I shan't go unless he asks me. 除非他请我，否则我是不去的。

I shall go, whether he asks me or not. 不管他请不请我，我都要去。

Come with me if you have time. 如果你有时间请跟我来。

I want to watch a basketball match if I'm well tonight.

如果今晚我好了的话，我要看一场篮球赛。

由and连接的简单句，可以用条件状语从句来改写。例如：

Run faster and you'll catch up with him. 跑快点儿你就会赶上他。

=If you run faster, you'll catch up with him. 如果你跑得快点，你就会赶上他。

5）结果状语从句

结果状语从句由so that, so… that引导。例如：

He has lost his bike so that he can't come to school on time.（结果状语）

他去了自行车，所以不能准时到校。

Your shirt were so dirty that you must wash it.（结果状语）

你的衬衣这么脏，你应该把它洗洗。

注意：

由so…that引导的状语从句若是表示否定意思，可以用too…to（太…而不能）来替换。例如：

She was so angry that she could not say a word.

=She was too angry to say a word. 她气得说不出话来。

6）让步状语从句

让步状语从句一般用though（虽然）、although（虽然）、even though（即使）引导。例如： Though/Although he tried hard, he was not successful. 他虽然努力尝试，但没有成功。 He went on working though it was very late. 虽然很晚了，他还在继续工作。

注意：

1．汉语中的“虽然…但是…”在英语中用连词though就可以了，或单独使用but连接两个并列句也可以，但不能在一个句子中同时用这两个连词（主句前不用连词）。

例如：“虽然我很喜欢照顾我姐姐的婴儿，但她不让我干”。

这个句子我们可以用下面两种方法来表达。

Though I like looking after my sister's baby, she doesn't let me do it.

I like looking after my sister's baby, but she doesn't let me do it.

=though可以与yet连用，这里yet虽然意思与but相同，但yet不是连词，而是副词。例如：Though it was cold, yet he went out without a coat.

虽然很冷，但他没穿外衣就出去了。

二、复习时需要注意的要点

（1）当整句句子处于过去时的情况下，主句用过去完成时，从句用一般过去时。

（2）当整句句子处于将来时的情况下，总是主句用一般将来时，从句用一般现在时。

（3）由when引导的时间状语从句，句子处于将来时的情况下，与所有的时间状语从句一样，主句用一般将来时，从句用一般现在时。
