2019年秋人教版八年级Unit 10 if引导的条件状语从句讲和练(含答案及解析)

2019年秋八年级上册单元语法讲与练if引导的条件状语从句语法精讲1.条件状语从句的含义由一个主句和一个或一个以上的从句构成的句子叫复合句。

在复合句中作状语的句子叫作状语从句。

状语从句根据它表达的意思可分为很多种，if引导的句子在复合句中表示条件，作主句的条件状语，因此称为条件状语从句。

If you don’t hurry，you’ll be late.如果你不快点，你将会迟到的。

If he comes，let me know.如果他要来，通知我。

2.if引导的条件状语从句的结构if引导的条件状语从句在句中的位置比较灵活，可以放在主句之前(这时要和主句用逗号隔开)，也可以放在主句的后面(不用逗号)。

条件状语从句的结构为：if+陈述句，主语+谓语(=主语+谓语+if+陈述句)。

意为“如果……就……”。

If you ask him，he will tell you the answer.如果你问他，他就会告诉你答案。

I hope to visit her if I’m free.如果我有空，我希望去看望她。

3.if引导的条件状语从句与主句时态的一致性在复合句中，从句中动词的时态在一定程度上受到主句动词时态的制约，英语语法中称为时态呼应。

（1）在含有条件状语从句的复合句中，如果主句是一般将来时，从句则用一般现在时代替一般将来时表将来。

If it rains，I will stay at home.如果下雨，我将待在家里。

If you study hard，you will pass the examination.如果你努力学习，就能通过这次考试。

（2）如果主句含有must，may，can等情态动词，从句也要用一般现在时。

If you drive too fast，you may have an accident.如果你把车开得太快，你可能会出事故。

You must stop if the traffic light is red.如果红灯亮了，你必须停下来。

人教版初中英语八年级上册 If 引导的条件状语从句

= If you study hard, you will pass the exam. Hurry up, or you will miss the train. 快一点，否则你将赶不上火车。
= If you don't hurry up, you will miss the train.
注意：为了避免重复，条件状语从句中常使用do( does, did ) 来代替上文提到的动作。
- I think I will ride my bike. - If you do, you'll be late.
巩固练习
.

1）如果明天下雨，我们就不去野餐。
If it rains tomorrow, we will not go for a picnic.
2) 如果你的孩子们在街上大声喊叫，你能怎么办？ What can you do if your children shout on the street?
定义：if “如果, 假如” 它引导的句子表示某事发生所需的条件，即“在…条件下，某事才能发生”，在句子中充当状语，因此称之为条件状语从句。
