由if/unless等引导的表示条件的句子，就叫条件状语从句。
e.g:If you put wood into water, it floats.如果你把木头放到水里，它就会浮起来。
Unless you keep ice cream in a fridge, it melts.除非你把冰淇淋放进冰箱，不然它就会融化。
二、时态1．当主句和从句所表示的是原理、客观真理、规则时，主句是一般现在时（包括祈使句和含有情态动词can/may/must等），从句也要用一般现在时。
例如：1) If you put a piece of paper into water, it gets wet．如果你把一张纸放进水中，它会变湿。
(原理)2)Be careful if you cross the road.(祈使句)3) You must see the doctor if you are ill.( 含有情态动词）2. 在if条件状语从句中，如果从句谈论的是一个可能发生的事实及其产生的相关结果，主句用一般将来时，从句用一般现在时。
e.g:1) If it rains tomorrow, we will not go to the zoo.2) If you go to bed earlier, you won't feel tired in the morning.3. 如果从句用现在进行时或现在完成时，主句需用一般将来时。
1）If you are looking for Peter you’ll find him upstairs.如果你是在找彼得，上楼就会找到他。
