7、What is he going to do when he grows up? 他长大了想干什么？ We are leaving for Xiamen tomorrow if it doesnt rain. 如果明天不下雨, 我们就去厦门。 We will buy that microwave next week if its price keeps going down. 如果价格持续下降,下个礼拜我们就买那台微波炉。 If +, Ill / youll + 条件结果1. 结构For example: If you study, Ill be happy. wear jeans to sc

8、hool, youll be sorry. get up late, youll be late. eat too much, youll be fat. wash your clothes yourself 有时，我们可以使用并列结构的祈使句来表达if引导的条件句。如：If you set your alarm clock, you wont oversleep.如果你上闹钟, 你就不会睡过头了。Set your alarm clock, and you wont oversleep. If you give him an inch, he will take a mile. 他会得寸进尺。

9、 Give him an inch, and he will take a mile. If you dont 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/else he will starve.2. 用法(1)条件状语从句通常由连词if引导, 意为“如果、假如”, 主句不能用be going to表示将来, 而应该用shall, will。e.g. If you leave now, you are never going to regret it. (错误) If you lea

10、ve now, you will never regret it. (正确)(2) if “如果”, 引导条件状语从句, 主句用一般将来时, 从句则用一般现在时，如： If it rains tomorrow, I shant climb the hills.注意: 宾语从句中的if与条件状语从句if的区别。宾语从句中的if“是否”相当于whether, 引导宾语从句, 时态需根据语境确定。I dont know if it will rain tomorrow. 我不知道明天是否会下雨。在阅读英文文章时, 我们有可能看到这样的句子：If my father will give me perm

11、ission, I shall spend a few months abroad. 如果我父亲同意, 我将在国外待几个月。If you will take the trouble to read his letter carefully,you will see what he means. 如果你肯花一些时间来认真读他的信，你就会明白他是什么意思了。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：If he

12、 gets my letter in time, hell 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, hell be able to change his plans.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.
