1、第12讲 Unit 6语法篇 _总结和理解if条件状语从句。Grammar: If从句 (2)一、引导条件状语从句最常用的连词是if，常见的if条件状语从句表示在某条件下，某事很可能发生。e.g. If you ask him, he will help you 如果你请他帮忙，他会帮你的。 If he does not work hard, he will fail his exams 如果他不努力，考试就要不及格了。 二、If从句的时态1. if从句用一般现在时，主句用一般将来时。 e.g. If he runs, hell get there in time. 如果他跑着去，他就会及时赶

2、到那儿。2. if从句用一般现在时，主句用情态动词+动词原形。e.g. She may come with us if she arrives in time. 如果她来得及时，就可以和我们一道去。三、if 引导的条件状语从句位置灵活，可直接放在主句后面，也可以放在句首。放在句首时，从句后面要用逗号和主句隔开。e.g. Ill go to see you if I have time. 如果有时间，我就去看你。 If it rains tomorrow, well stay at home. 如果明天下雨，我们就待在家里。四、同义句转换用“祈使句 and / or 一般将来时的句子”转换。e.

3、g. If you work hard, youll pass the exam easily. Work hard, and youll pass the exam easily. 努力学习，你将很容易通过考试。If you dont hurry up, youll miss the train. Hurry up, or youll miss the train. 快点儿，否则你就赶不上火车了。1.Boys and girls, calm down and focus on the paper _ you begin to think about the answers. Be confi

4、dent. You can do it! A.as if B.as soon as C.although D.but2.I was late for class yesterday _ there was something wrong with my bike. A.when B.that C.until D.because3.He lost his new pen. _. A.Thats right B.Thats a shame C.Good luck D.All right 4.I am sure he will _ pass the exam.A. can B. be able to

5、 C. able D. could5.If Tom _ the game ,we will give him a surprise .A.win B.wins C.won D.winning解析：1. B as if“好像”；as soon as“一就”；although：虽然，尽管“；but“但是”。 由句意“ 你们一开始考虑答案就要平静下来并把精力集中在试卷上”2.D 由前半句句意“我昨天上课迟到了”和后半句句意“我的自行车出故障了”可知，前后两部分 在逻辑上是因果关系，故选D。 3.B Thats right.“对。”；Thats a shame.“真遗憾。”；Good luck.“祝你

6、好远。”；All right.“好的；可以。”由上句句意“他把新钢笔弄丢了”可知选B。4.B 本题可用排除法来做。can与could 不能与will 连用，排除A、D两项；而able是形容词，will后接动词原形，故选B。 5.B 在含有if引导的条件状语从句的主从复合句中，若主句为一般将来时，if引导的条件状语从句用一般现在时表示将来。从句的主语为Tom,所以谓语动词用第三人称单数形式，故选B。 基础演练I.用所给动词的适当形式填空1.
