Lesson 1 Masterpieces 导学案
1. 掌握本课单词及短语
2. 掌握名词性从句(主语从句,宾语从句,标语表语从句)
3. 名词性从句的正确判断以及运用
一、主语从句
1.什么是主语?
主语是执行句子的行为或者动作的主体。
Eg: I like English.
2.什么是主语从句?
在复合句中作主语的从句叫主语从句。
What he wants to tell us is not clear.
3. 主语从句的连接词:
(1) 从属连词that,whether
(2)连接代词what,who,which,whatever,whoever
(3)连接副词how,when,where,why等词引导。
注意:that在句中无词义,只起连接作用;连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用,在从句中充当从句的成分
例如:It is known to us how he became a writer.
Where the English evening will be held has not yet been announced.
4. 主语从句中连接词的使用:
(1)由连词that引导的主语从句:
引导词that无含义,在句中不做成分,不可以省。
例如:That you will win the medal seems unlikely.
(2)用连词 whether 引导的主语从句:
whether有含义(是否),在句中不做成分,不可以省。
例如:Whether she is coming or not doesn’t matter too much.
备注:It doesn’t matter if 是固定句型。
(3)用连接代词引导的主语从句(在由连接代词who, whose, whom, which, what, whoever, whomever, whichever, whatever引导的名词性从句中,其连接代词在句中起名词性作用,担当一定成分,有意义)。
例如:What you need is more practice.
*whatever, whoever, whichever引导的主语从句的区分:
Whatever 相当于anything that , 是 what 的强
