人教版英语八年级上册Unit10(语法专项突破):if引导的条件状语从句
【语法专项突破】:if引导的条件状语从句生活中,我们常常用“如果”作假设,来谈论某些情况产生的某些影响。
而在英语中,这种假设常用条件状语从句来表示。
下面让我们解读一下if条件状语从句:if 意为“如果”,由它引导的条件状语从句表示假如有从句的动作发生,就会有主句的动作发生。
从句可以放在主句前或主句后;当从句置于主句前时,须用逗号与主句隔开。
If I go there,I’ll take her some flowers.如果我去那儿,我将给她带些花。
if条件状语从句的时态:当谈论将来可能出现的情况时,条件状语从句用一般现在时表示将来,主句常用一般将来时。
即“主将从现”。
We'll stay at home if it rains tomorrow.如果明天下雨,我们将待在家里。
if条件状语从句有时可以与其他句型进行转化:1.与祈使句+and/or+一般将来时的句子转化。
If you get up early,you won't be late for school.如果你早起床,你上学就不会迟到。
→Get up early,and you won't be late for school.早点起床,你上学就不会迟到。
→Get up early,or you will be late for school.早点起床吧,否则你上学就会迟到。
2.与with或without进行转化。
If there is no water,we can't live.如果没有水,我们就不能生存。
→We can't live without water.没有水我们不能生存。
1.如果if 引导的从句中用了will ,will 在此处是情态动词,表示意愿。
If you will help me ,I'll finish it on time.如果你愿意帮我,我会按时完成的。
2.在谈论将来可能出现的情况时,主句还可以是含有其他情态动词的句子或者是祈使句。

一般现在时。 If you drive too fast, you may have an accident. You must stop if the traffic is red.

前须有逗号隔开
