班级 姓名 学号 分数 Unit 6 Traveling around Asia 重点语法if引导的条件状语从句 （时间：60分钟，满分：100分） 条件状语从句是在复合句中作条件状语的句子。表示假如有从句的动作发生就会有主句的动作发生。条件状语从句常由连词if引导。 (一)连接词if if如果，是引导条件状语从句的连接词，表示主句中动作发生的条件。 ☞ If you get up early, you will catch the bus. 如果你早起的话，就能赶上那班公共汽车。 ☞ You must see the doctor if you are ill. 如果你生病了，就必须去看医生。 (二)if引导的条件状语从句的构成 构成方式为＂主句+if引导的条件状语从句＂或＂if引导的条件状语从句+主句＂。在含有条件状语从句的复合句中，如果主句在前，从句在后，主从句之间不用标点；如要强调从句的内容，则把从句放在主句的前面，这时主从句之间要用逗号隔开。 ☞ I will go to his birthday party if he invites me. =If he invites me, I will go to his birthday party. 如果他邀请我，我会去参加他的生日聚会。 (三)if引导的条件状语从句的时态 在一般情况下，如果主句表示将来的意义，从句用一般现在时表将来。常见的有以下几种： ☞ You will be late for school if you get up late. 如果你起晚了，上学将会迟到。 ☞ If it rains tomorrow, we won’t go to the Great Wall. 如果明天下雨，我们就不去长城。 1、 单项选择(本大题共50小题，每小题2分，共100分) 1．—Do you know if he _______tomorrow? —No. But if he _______, I’ll call you.
