11. Explanation 一. if 条件句 1. 条件状语从句中的 “ 主将从现 ” 现象， 即主句为将来时态时，它所引导的条 件状语从句使用一般现在时表达将来 的意味，这时主句和从句所表达的时 态在意义上仍然保持一致。

12. 如 : If he goes to England, he will have to learn English. 如果他要去英格兰，他将不得不 学英语。 If it is fine tomorrow, we will have a picnic somewhere. 如果明天天气好，我们就到什么 地方野餐去。

13. 这里 if 所引导的是真实条件句 (real conditional), 即所假设的条件有可能成 为现实，表达假定所假设的条件实现 时会出现的情况或会采取的行为。有 时，我们可以使用并列结构的祈使句 来表达这种类型的条件句。

14. 如 : If you set your alarm clock, you won’t oversleep. 如果你上闹钟，你就不会睡过头 了。 Set your alarm clock, and you won’t oversleep.

15. If you don’t give him some food, he will starve. 如果你不给他一点吃的，他就会饿 死。 Give him some food, or he will starve.

16. 在 if- 分句中用 “will ＋动词原形 ” 并不 单纯表示将来意义，这里的 will 是个 表示 “ 意愿 ” 的情态动词，相当于 be willing to （愿意）。 要注意这种带 “will ＋动词原形 ” 的 if- 分句在某些场合是不可以随便用的， 比如我们可以说：

17. If he gets my letter in time, he’ll be able to change his plans. 如果他及时收到我的信，他就能 改变他的计划。 却不可以说成： If he will get my letter in time, he’ll be able to change his plans.

18. 另外，在 if- 分句中还可能使用 “would ＋动词原形 ” 的结构，这种用 法还是表示 “ 意愿 ” ，常用于表示客气 的请求，这时主句动词既可以用 will/ shall ＋动词原形，也可以用 would/ should/ could/ might ＋动词原形。

19. 如 : If you would try Italian food, you would like it. 如果你愿意尝尝意大利食物，你会喜 欢它的。 If you would reserve the seats, we would be sure of a comfortable journey. 如果你愿意订座，我们将肯定会有一 个舒适的旅程。
