II.疑问词?+?ever和no?matter?+?疑问词的区别： ? ①疑问词?+?ever可引导名词性从句，在主从句中要充当一定的部分。?Whoever?breaks?the?rule?must?be?punished.?You?can?choose?whatever?you?like?in?the?shop.? ②疑问词?+?ever还可引导让步状语从句。如：?Whoever?breaks?the?rule,?he?must?be?punished,? Whatever?you?do,?you?must?do?it?well.? ③no?matter?+?疑问词只能引导让步状语从句。?No?matter?what?you?do,?you?must?do?it?well.? No?matter?who?breaks?the?rule,?he?must?be?punished.? 通过把2个简单的句子合并成一个名词性从句，练习疑问词引导的名词性从句。并提出注意点：1）疑问词后的名词性从句语序要用陈述句的语序2）任何连接名词性从句的wh-连词都不能省。再通过判断和填空的练习巩固这部分内容。 * 设计说明：先简单复习“it” 的功能。在英语中为了避免头重脚轻，我们经常把主要信息放在句子后面部分，而用it作形式主语。然后讲解it的用途 ：当真正主语为从句或不定式时，最好用it作形式主语，当真正主语为v-ing时，还是把v-ing主语放句首。之后配上一定练习和造句进行巩固。 * 这是语法教学上升到语篇层面的运用, 也是把枯燥的语法知识运用到实际生活中，通过完成对话再次复习本节课所授知识。 * 通过书后练习巩固本课学习内容，通过预习为下一课时做准备。 * Grammar and usage 2 Empty subject it Revision Go over what we have learnt about Noun clauses introduced by question words in last lesson We use a question word to introduce a noun clause when the clause is a wh-question. The clause can function as the subject, object or predicative of the sentence. Noun Clauses Introduced by Question Words What was he doing ?

I want to know. object clause 宾语从句 I want to know what your first impression of him is. How can I make a grammar lesson interesting? That is my question. predicative clause 表语从句 My question is how I can make a grammar lesson interesting. 疑问词的使用 名词性从句中疑问词的选择主要根据名词性从句中的具体意义，正确的选择 who, which, when, where, why, how 等连接词，这些连接词既具有疑问含义，又起连接作用，同时在从句中充当各种成分。 1.
