Unless it rains, the game will be played.除非下雨,比赛将照常进行。,条件状语从句,3、so/as long as只要 You may borrow my book as long as you keep it clean. 只要你保持书的清 洁,你就可以把我的书借去。 So long as youre happy, it doesnt matter what you do. 只要你高兴,你做什么都没有关系。,条件状语从句,二、时态问题 在条件状语从句中,要注意“主将从现“的规定,即主句用一般将来时,从句用一般现在时表示将来时。 I will come to see you if I have time. 我有时间,我就来看你。 常见考法 对于条件状语从句的考查,多以单选和完形填空的形式,从时态的角度设题,考查学生灵活运用的能力,或从连词的意义角度让大家选择连词。,条件状语从句,典型例题: If he _in half an hour, we _wait for him. A. wont come ,wont B. wont come ,dont C. doesnt come ,wont D. will come ,dont 解析:本题考查条件状语从句“主将从现“的运用。题干的意思是“如果他一小时后不来,我们将不会等他了“,从“in half an hour“,“一小时后“可知本句说的是未来的事,那么if引导的条件状语从句要用一般现在时表示将来时,主句要用一般将来时。 答案:C,条件状语从句,1. If it _tomorrow, we _ to climb mountains. A. doesnt rain; go B. wont rain; will go C. wont rain; go D. doesnt rain; will go 2Do you know if _ tomorrow morning? No. I will call you if she _ back. A. she will come; comes B. she comes; will come C. will she come; comes D. will she come; will come,条件状语从句,3Well go to the park if it_ rain tomorrow. A. dont B. doesnt C. wont 4We are not sure if it _ tomorrow. If it _ , our sports meeting will be put off. A. rains; rains B. rains; will rain C. will rain; will rain D. will rain; rains,条件状语从句,误区提醒 if 既可以引导条件状语从 句,表示“如果“,也可以引导宾语从句,表达“是否“。辨别它在这两种从句中的时态是我们经常容易出错的地方。另外,if 和unless的用法也需注意,条件状语从句,5.
