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, he’ll get there in time.
如果他跑着去,他就会及时赶到那
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. 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 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.g. 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。
