If意为“如果”，引导条件状语从句时，既可在 主句前，也可在主句后。若放在句首，从句后面 要加逗号与主句隔开。 例：如果你去那儿，我也会去。 ________________________ If you go there, I’ll go, too. Grammar If +…, 条 件 结 果 2. 句型结构： 从句 主句 I’ll / you’ll +… 3. 时态： 主句是一般将来时，从句一般现在时。 主句是有情态动词may/might/can/must/ should等句子，从句一般现在时。 If he comes, he will bring his violin. If you want to lose weight, you must eat less bread. 主句是祈使句，从句一般现在时。 Don’t carry the box if you are not strong enough. 4. 句型转换 （1）借助“祈使句+and/or +句子（一般将来时 结构）” 来转换。其中，在句意上and表 示顺承；or表示转折，意为“否则”。 If you work hard, you’ll pass the exam easily. =Work hard, and you’ll pass the exam easily. =Work hard, or you won’t pass the exam easily. （2）借助without或with来转换条件状语从句。 If there is no water, fish will die. =Fish will die without water.
