Unit 10 If you come to my party, you’ll have a great time.


（1）if 引导的条件状语从句
条件状语从句是在复合句中作条件状语的句子。表示假如有从句的动作发生就会有主句的动作发生。条件状语从句常由连词if引导。
(一)连接词if
if如果，是引导条件状语从句的连接词，表示主句中动作发生的条件。
☞ If you get up early, you will catch the bus. 如果你早起的话，就能赶上那班公共汽车。
☞ You must see the doctor if you are ill. 如果你生病了，就必须去看医生。
(二)if引导的条件状语从句的构成
构成方式为＂主句+if引导的条件状语从句＂或＂if引导的条件状语从句+主句＂。在含有条件状语从句的复合句中，如果主句在前，从句在后，主从句之间不用标点；如要强调从句的内容，则把从句放在主句的前面，这时主从句之间要用逗号隔开。
☞ I will go to his birthday party if he invites me.
=If he invites me, I will go to his birthday party. 如果他邀请我，我会去参加他的生日聚会。
(三)if引导的条件状语从句的时态
在一般情况下，如果主句表示将来的意义，从句用一般现在时表将来。常见的有以下几种：
1. 主句谓语中有will, shall, won’t 表示将来时，从句用一般现在时。
☞ You will be late for school if you get up late. 如果你起晚了，上学将会迟到。
☞ If it rains tomorrow, we won’t go to the Great Wall. 如果明天下雨，我们就不去长城。
2.主句中含有can, may, must等情态动词时，从句用一般现在时。
☞ If I finish my homework, I can watch TV. 如果我完成了家庭作业，就可以看电视。
3.主句是祈使句，从句用一般现在时。[来源:Zxxk.Com]
☞ Don’t forget to lock the door if you are the last one to leave. 如果你最后一个离开，别忘了锁门。
4.主句的谓语动词是want, hope, wish等词。
☞ I hope to visit her if I’m free. 如果我有空，我希望去拜访她。
(四)注意事项
1.在if引导的条件状语从句中，当主句是一般将来时态时，一般不使用be going to结构，而要用will。
☞ I’ll help you with your English if I am free tomorrow. 如果明天我有空，我会帮你学英语。
2.在if引导的条件状语从句中不能够使用some，而要用any。
☞ If you have any questions to ask, please come to my office. 如果你有问题要问的话，请到我办公室来。
(五)同义句转换
if引导的条件状语从句可以转换成简单句，其方法如下：
1.借助＂祈使句+and/or+简单句＂。其中and表示句意顺承，or表示转折。 [来源:Z#xx#k.Com]
☞ If you work hard, you’ll pass the exam.
=Work hard, and you’ll pass the exam. 如果你努力学习，你就会通过考试。
☞ If you don’t hurry up, you’ll be late.
=Hurry up, or you’ll be late. 如果你不快点，你将会迟到。
2.借助介词with 或without来转换。
☞ If you help me, I’ll finish my job soon.
=With your help, I’ll finish my job soon. 如果你帮我，我将很快完成我的工作。
☞ If there is no water, fish may die.
=Fish may die without water. 如果没有水，鱼可能会死。

（2015广西崇左）You will be late for school ________ you don’t get up early.
A. but B. and C. if D. or
【答案】C
述句＂，表示 ＂……，否则，……＂，结合句意可知条件状语从句，故选C。
(2)情态动词should的用法
　情态动词should和can，may，must一样，没有人称和数的变化，有词意，但都不能单独作谓语，必须和后面的动词原形一起构成谓语。基本意思是＂应当，应该＂，常用来表示建议或命令等。如：
☞ You should work harder.
你应该更努力地工作。
否定式和疑问式的构成与can ,may 和must一样。如：
☞ You shouldn’t play soccer in the street.
你们不应该在街上踢足球。
☞ Who should pay the taxi driver?
谁应该付出租车钱？
【注意】
常用句型You should /shouldn’t do sth 表示＂建议某人（不）做某事＂。其他表示＂建议＂的句型还有：Why not do sth? /Why don’t you do sth? /How about doing sth? /What about doing sth? /It’s a good idea to do sth /You’d better do sth等。
should作为情态动词用，常常表示意外、惊奇、不能理解等，有＂竟会＂的意思，例：
☞How should I know? 我怎么知道？
☞Why should you be so late today? 你今天为什么来得这么晚？
should有时表示应当做或发生的事，例：
☞We should help each other.我们应当互相帮助。
我们在使用时要注意以下几点：
1. 用于表示＂应该＂或＂不应该＂的概念。此时常指长辈教导或责备晚辈。例：
☞You should be here with clean hands. 你应该把手洗干净了再来。
2. 用于提出意见劝导别人。例如：
☞You should go to the doctor if you feel ill. 如果你感觉不舒服，你最好去看医生。
3. 用于表示可能性。should的这一用法是考试中常常出现的考点之一。例：
☞We should arrive by supper time. 我们在晚饭前就能到了。
☞She should be here any moment. 她随时都可能来。
