状语从句的练习题(2)

　　（五）结果状语从句

　　结果状语从句是表示事态结果的从句，通常主句是原因，从句是结果。由so that （从句谓语一般没有情态动词）, so … that, such … that等引导。

　　e.g. She was ill, so that she didn’t attend the meeting.He was so excited that he could not say a word. She is such a good teacher that everyone admires her.

（六）条件状语从句

　　条件状语从句分真实性（有可能实现的事情）与非真实性（条件与事实相反或者在说话者看来不大可能实现的事情）条件句。引导条件状语从句的词（组）主要有if, unless, so (as) long as, on condition that, so (as) far as, if only ( = if )。注意：条件从句中的if 不能用whether替换。

　　e.g. If he is not in the office, he must be out for lunch. You may borrow the book so long as you keep it clean. So far as I know（据我所知）, he will be away for three months. You can go swimming on condition that ( = if ) you don’t go too far away from the river bank.

　　If he had come a few minutes earlier, he could have seen her.

（七）让步状语从句

　　让步状语从句可由although, though, as, even if (though), however, whatever, whether … or, no matter who (when, what, …) 等引导。注意：as引导的让步状语从句一般是倒装的。

　　e.g. Though he is a child, he knows a lot.Child as he is, he knows a lot. Whatever ( = No matter what ) you say, I’ll never change my mind.
