eg:I'm leaving for Beijing.

⑸引导表语从句、同位语从句时，只能用whether。
eg:①The question is whether they will agree with it.
②There is a doubt whether he is fit for the job.
⑹作discuss等动词的宾语时，只能用whether。
eg:They're discussing whether they should accept his invitation.
㈢特殊疑问词引导的宾语从句
eg: I wonder why they came here late again.
注：⑴主从句4关系
⒈时态：主过去，从过去；主现在，从所需。但客观事实、科学真理、原理、公理、定律、法则、规则、谚语、自然现象和生活常识等不受此限制，只用一般现在时。
eg:①He says he is happy every day.
②They said they were having a meeting at that time.
③When we were children,our teacher often told us that the earth turns around the sun.
⒉语序：从句一般用陈述/正常语序。但What’s wrong/the matter/the trouble/up with sb?What happened?本身即为陈述/正常语序。
eg:①We didn’t know why he was absent from the meeting yesterday.
②Tom said there were no classes yesterday afternoon.
③Mike asked what was the matter with me.
⒊疑问词：必须位于从句句首。
eg:I don't know what I should do.
⒋“疑问词+to do”：当从句主语与其逻辑主语一致时，可用“疑问词+to do”结构。
eg:I don't know what to do.(=I don’t know what I should do.)

2.what和how引导的感叹句
⑴一般情况下，what为adj.，只对名词进行感叹，how为adv.，对adj/adv原级进行感叹。
⑵感叹句的结构为：
What+a/an+adj+n(可单)(+主+谓)+其它！
What+adj+ns(可复)(+主+谓)+其它！ How+adj/adv(原级)(+主+谓)+其它!
What+adj+n(不可数)(+主+谓)+其它！
eg:①What a beautiful flower it is!
②What beautiful flowers they are!
③What nice weather it is!
④How nice it is!
⑶判断用what或how感叹的方法。
首先，找到句子的主语。
然后，根据主语前的单词的词性确定用what或how来感叹。如果主语前为名词，则用what感叹；如果主语前为adj/adv,则用how来感叹。

( )1.______ mooncakes they are!
A.What delicious B.How delicious C.What a delicious D.How a delicious
