Unit 6 Enjoying Cycling Topic 3 条件状语从句 （时间：60分钟，满分：100分） 可以导条件状语从句的从属连词有很多，例如 if (假如，如果)，unless (除非），suppose (倘若), as long as (只要)等。我们现在主要学习由 if 和 unless 引导的条件状语从句。如: If it doesn't rain tomorrow, we are going to the Great Wall. 如果明天不下雨，我们就去长城。 If you are tired, you may go to bed. 你如果累了，就去睡觉。 He won't be able to catch up with us unless he runs faster.  他不可能赶上我们，除非他跑得更快此。 He'll go there unless it rains. 如果不下雨，他就会去那儿。 温馨提示 1. if 引导的状语从句经常可以和 unless 引导的状语从句互相转换。如: He'll go there if it doesn't rain. = He'll go there unless it rains. 2.和部分时间状语从句一样，在条件状语从句中， 如果主句是一般将来时，从句则用一般现在时表示将来。如:If everyone obeys the traffic rules, the roads will be safer. 1、 单项选择(本大题共50小题，每小题2分，共100分) 1．I will leave here as soon as I finish the dinner ________ she asks me to stay.
