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


（1）if 引導的條件狀語從句
條件狀語從句是在復合句中作條件狀語的句子。表示假如有從句的動作發(fā)生就會有主句的動作發(fā)生。條件狀語從句常由連詞if引導。
(一)連接詞if
if如果，是引導條件狀語從句的連接詞，表示主句中動作發(fā)生的條件。
? If you get up early, you will catch the bus. 如果你早起的話，就能趕上那班公共汽車。
? You must see the doctor if you are ill. 如果你生病了，就必須去看醫(yī)生。
(二)if引導的條件狀語從句的構成
構成方式為＂主句+if引導的條件狀語從句＂或＂if引導的條件狀語從句+主句＂。在含有條件狀語從句的復合句中，如果主句在前，從句在后，主從句之間不用標點；如要強調從句的內容，則把從句放在主句的前面，這時主從句之間要用逗號隔開。
? I will go to his birthday party if he invites me.
=If he invites me, I will go to his birthday party. 如果他邀請我，我會去參加他的生日聚會。
(三)if引導的條件狀語從句的時態(tài)
在一般情況下，如果主句表示將來的意義，從句用一般現(xiàn)在時表將來。常見的有以下幾種：
1. 主句謂語中有will, shall, won’t 表示將來時，從句用一般現(xiàn)在時。
? You will be late for school if you get up late. 如果你起晚了，上學將會遲到。
? If it rains tomorrow, we won’t go to the Great Wall. 如果明天下雨，我們就不去長城。
2.主句中含有can, may, must等情態(tài)動詞時，從句用一般現(xiàn)在時。
? If I finish my homework, I can watch TV. 如果我完成了家庭作業(yè)，就可以看電視。
3.主句是祈使句，從句用一般現(xiàn)在時。[來源:Zxxk.Com]
? Don’t forget to lock the door if you are the last one to leave. 如果你最后一個離開，別忘了鎖門。
4.主句的謂語動詞是want, hope, wish等詞。
? I hope to visit her if I’m free. 如果我有空，我希望去拜訪她。
(四)注意事項
1.在if引導的條件狀語從句中，當主句是一般將來時態(tài)時，一般不使用be going to結構，而要用will。
? I’ll help you with your English if I am free tomorrow. 如果明天我有空，我會幫你學英語。
2.在if引導的條件狀語從句中不能夠使用some，而要用any。
? If you have any questions to ask, please come to my office. 如果你有問題要問的話，請到我辦公室來。
(五)同義句轉換
if引導的條件狀語從句可以轉換成簡單句，其方法如下：
1.借助＂祈使句+and/or+簡單句＂。其中and表示句意順承，or表示轉折。 [來源:Z#xx#k.Com]
? If you work hard, you’ll pass the exam.
=Work hard, and you’ll pass the exam. 如果你努力學習，你就會通過考試。
? If you don’t hurry up, you’ll be late.
=Hurry up, or you’ll be late. 如果你不快點，你將會遲到。
2.借助介詞with 或without來轉換。
? If you help me, I’ll finish my job soon.
=With your help, I’ll finish my job soon. 如果你幫我，我將很快完成我的工作。
? If there is no water, fish may die.
=Fish may die without water. 如果沒有水，魚可能會死。

（2015廣西崇左）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 ＂……，否則，……＂，結合句意可知條件狀語從句，故選C。
(2)情態(tài)動詞should的用法
　情態(tài)動詞should和can，may，must一樣，沒有人稱和數(shù)的變化，有詞意，但都不能單獨作謂語，必須和后面的動詞原形一起構成謂語?；疽馑际牵?，應該＂，常用來表示建議或命令等。如：
? You should work harder.
你應該更努力地工作。
否定式和疑問式的構成與can ,may 和must一樣。如：
? You shouldn’t play soccer in the street.
你們不應該在街上踢足球。
? Who should pay the taxi driver?
誰應該付出租車錢？
【注意】
常用句型You should /shouldn’t do sth 表示＂建議某人（不）做某事＂。其他表示＂建議＂的句型還有：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作為情態(tài)動詞用，常常表示意外、驚奇、不能理解等，有＂竟會＂的意思，例：
?How should I know? 我怎么知道？
?Why should you be so late today? 你今天為什么來得這么晚？
should有時表示應當做或發(fā)生的事，例：
?We should help each other.我們應當互相幫助。
我們在使用時要注意以下幾點：
1. 用于表示＂應該＂或＂不應該＂的概念。此時常指長輩教導或責備晚輩。例：
?You should be here with clean hands. 你應該把手洗干凈了再來。
2. 用于提出意見勸導別人。例如：
?You should go to the doctor if you feel ill. 如果你感覺不舒服，你最好去看醫(yī)生。
3. 用于表示可能性。should的這一用法是考試中常常出現(xiàn)的考點之一。例：
?We should arrive by supper time. 我們在晚飯前就能到了。
?She should be here any moment. 她隨時都可能來。
