初中英语――if指引的条件状语从句（注意&练习）注意：学习"if"指引的条件状语从句的用法,此刻总结一下:if条件句不一般,几个重点记心间;条件句,放在前,逗号要放句中间。

条件句表可能，主句多用未来时；条件句表事实，主句常用此刻时。

在if指引的条件状语从句中，假如从句讨论的是一个有可能发生的事实及其产生的有关的结果，主句用一般未来时态，从句用一般此刻时态。

如：Wecanwalkthereifwecan'tfindabus.Ifitrainstomorrow,wewillnotgotothezoo.Whatwillyoudoifyouf indapandaindanger.假如if条件句讨论的是重复发生和预示要发生的情形和事件，则主从句大多用一般此刻时态。

如：Ifbearsareindanger,theyattackpeople.在if指引的条件状语从句中，if和条件句地点灵巧，可直接放在主句后边，若if条件句放句首，从句后边要加逗号，和主句分开。

还要注意前后时态一致原则if条件状语从句的时态练习一．在正确的答案下划一条线。

If you fail in the exam,you will let him down．如果你考试不及格,你会让他失望的.If you have finished the homework， you can go home．如果你作业做完了就可以回家了.另外，if从句还表示不可实现的条件或根本不可能存在的条件，也就是一种虚拟的条件或假设。

从句多用一般过去时或过去完成时，表示对现在或过去的一种假设.如：If I were you，I would invite him to the party．如果我是你，我会邀请他参加聚会。

I would have arrived much earlier if I had not been caught in the traffic．要不是交通堵塞,我本会来得早一些。

另外你还要注意if 条件句的时态搭配1．if从句用一般现在时，主句用一般将来时If he runs he’ll get there in time. 如果他用跑的，他就会及时赶到那儿.The cat will scratch you if you pull her tail. 如果你拉猫的尾巴,它就会抓你。

if引导的条件状语从句[课本链接]If you do, you’ll be sorry. (Unit 5, Section A)[定义] :if引导的条件状语从句表示假如从句的动作发生，主句的动作就（不）会发生。

如：I’ll go to see you if I have time. 如果有时间，我就去看你。

If it rains tomorrow, we’ll sta y at home. 如果明天下雨，我们就呆在家里。

[时态呼应]在复合句中：⑴ 当主句是一般现在时或是一般将来时时；（2）当主句是祈使句时；（3）当主句含有情态动词时，if引导的条件状语从句通常用一般现在时。

如：If she doesn’t come, she will be sorry. 如果她不来，她会遗憾的。

Have a good rest if you are tired. 如果累了，你就好好休息一下。

We must study hard if we want to pass the final exam. 如果想通过期末考试，我们必须努力学习。

如：If you work hard, you’ll pass the exam easily. → Work hard, and you’ll pass the exam easily. 努力学习，你将很容易通过考试。

If you don’t hurry up, you’ll miss the train. → Hurry up, or you’ll miss the train. 快点儿，否则你就赶不上火车了。

If you leave now, you are never going to regret it. (错误)If you leave now, you will never regret it. (正确)(2)if “如果”，引导条件状语从句，主句用一般将来时，从句则用一般现在时，如：If it rains tomorrow, I shan’t climb the hills.(3)另外，主句是祈使句或含有情态动词，从句也用一般现在时。

如：Please call me if he comes next Sunday.Can you call the policeman if you are in the trouble.注意宾语从句中的if与条件状语从句if的区别。

宾语从句中的if“是否”相当于whether，引导宾语从句，时态需根据语境确定。

如果主句用一般现在时，从句可以根据具体情况选用时态，如果主句用一般过去时，从句必须用过去式的某种形式。

I don't know if it will rain tomorrow. 我不知道明天是否会下雨。

Our teacher said there was going to be a football match the next month.我们说下月将有场足球比赛。
