If we do nothing, the situation will get worse. 如果我们什么都不做，情况会变得更糟。 结构分析：这是一个主从复合句。主句是the situation will get worse，其中the situation 作主语；will get 作谓语；worse 作表语。从句是由If 引导的条件状语从句，we 作主语；do 作谓语；nothing 作宾语。 “If + 从句，+ 主句.”表示“如果……，……就会……”。注意：在if 引导的条件状语从句中，从句用一般现在时，主句用一般将来时，即遵循“主将从现”原则。 e.g. If you study hard, you will get good grades. 如果你努力学习，你就会取得好成绩。 If it rains, we will stay at home.如果下雨，我们就会待在家里。 Listen to the conversation and answer the questions. 1.
