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. 八、方式状语从句 方式状语从句常由as， as if （though）， the way， rather than等引导。 e.g. You must do the exercise as I show you. He acted as if nothing had happened. 九、比较状语从句 比较状语从句常用than， so （as） …… as， the more …… the more等引导。 e.g. I have made a lot more mistakes than you have. He smokes cigarettes as expensive as he can afford. The busier he is， the happier he feels. 十、使用状语从句时要注意的几个问题 1. 在时间和条件（有时也在方式、让步等）从句中，主句是一般将来时，从句通常用一般现在时表示将来。 e.g. We‘ll go outing if it doesn’t rain tomorrow. I‘ll write to you as soon as I get to Shanghai. (责任编辑：admin) |
