1. What will life be like in the future? 未来的生活会是什么样子? (p.41 Warming Up)

What ...like? “……像什么/怎么样/什么样子?”，此处like是介词，其宾语是what。

如：① What's the weather like there? 那儿的天气怎么样?

② What's your teacher like? 你老师是怎样一个人?

2. What happened to the people on the earth? 地球上的人出什么事了? (p.42 Listening Ex.3)

happen to“某人/某物发生了什么事，怎么了”。

如：① That autumn something unfortunate happened to my family. 那年秋天，我家发生了一件不幸的事。

3. It would be wonderful if (I had more free time)! 假如 (我有更多的自由时间)，那该多好啊! (p.43 Useful expression_rs)

什么是虚拟语气?虚拟语气表示说话人的主观愿望、猜测、建议或与事实不符的假设等，也可以表示可能性较小或不可能发生的情况，虚拟语气常用于复合句中。上句是一个含有条件状语从句的复合句，主句和从句的谓语动词使用了虚拟语气，表示“与现在事实相反的”一种假设。那么，当说话人想表示“与现在事实相反的”假设时，主句和条件状语从句的谓语动词的“模版形式”是怎样的呢?请观察如下，

如：① If I were you, I wouldn't accept her suggestion. 如果我是你，我不会接受她的建议。

② If I knew the answer to the question, I should (would) tell you. 如果我知道问题的答案，我会告诉你的。

③ If he were here, he might talk with you. 如果他在这儿，他可能会跟你谈谈的。

④ If I didn't do exercise every day, I wouldn't be so strong. 如果我不每天锻炼，我是不会这么强壮的。
