Grammar Focus
if引导的条件状语从句
1.if意为“如果”,引导条件状语从句,既可
放在主句前面,也可放在主句之后。若if条
件句放在句首,从句后面要加逗号与主句隔
开。
eg:If you go there,I'll go ,too.
如果你去那,我也会去。
Grammar
2.时态运用
在含有if引导的条件状语从句的主从复合句中,主句有下列情况之一时,从句要用一般现在时表示将来意义(主将从现原则)。
(1)主句是一般将来时。
eg:If he comes,he will bring his violin.
他如果来,就会带来他的小提琴。
(2)主句谓语含有情态动词may/might/can/must/should等。
eg:If we start now,we can finish the work on time.我们如果现在开始,就可以按时完成工作。
(3)主句是祈使句。
eg:Work hard,if you want to get good grades.
你如果想取得好成绩,就要努力学习。
3.句型转换。
(1)借助“祈使句+and/or+句子(一般将来时)”
这一句型来转换。其中,在句意上and表示顺承;
or表示转折,意为“否则”。
eg:If you study hard,you'll pass the exam easily.
如果你努力学习,你将很容易通过考试。
=Study hard and you'll pass the exam easily.
(2)借助without或with 来转换条件状语从句。
eg:If there is no water,fish will die.
=Fish will die without water.
如果没有水,鱼会死。
If you help me,I'll finish the work soon.
=With your help,I'll finish the work soon.
如果你帮助我,我将很快完成工作。
