语法专题：条件状语从句（1）if条件句：有可能性结果发生的行动，在这些句子中，动词的时态是不同的，if 引导的条件状语从句中，主句用一般将来时态，从句用一般现在时态（主将从现）If it doesn’t rain（从句）, we’ll have a picnic tomorrow（主句）.We’ll have a picnic tomorrow, if it doesn’t rain.（if引导的从句可置前可置后）（2）主祈从现（祈使句+if+一般现在时态）Put up your hands if you have any questions to ask. 如果你们有问题问的话，请举手。
当主语是you时，if 引导的条件状语从句可以与”祈使句+and/ or +简单句”进行句型转换。
And 表示句意顺承，or 表示转折，意为”否则”。
