Unit 5 Why do you like pandas？
第2课时 Section A(Grammar Focus—3c)
一、why引导的特殊疑问句
why引导的特殊疑问句，意为“为什么……？”，用来询问某事的原因。结构为“Why＋助动词的适当形式＋主语＋动词原形＋其他？/Why ＋be动词＋主语＋其他？”。
1．一般用法： 常用于询问原因。回答时常用because。如：
—Why does he look worried?
—Because he lost his key.
——他为什么看起来忧伤？
——因为他把钥匙丢了。
2．特殊用法： Why don't you＋动词原形＋其他？常用来提出建议或劝告，表示“为什么不……？”，相当于“Why not＋动词原形＋其他？”。如：
—Why don't you play basketball？/Why not play basketball?
—That sounds good.
——为什么不打篮球呢？
——那听起来不错。
二、where引导的特殊疑问句
where为疑问副词，意为“在哪里”，用来询问地点，一般由“where＋一般疑问句”构成其特殊疑问句。本单元where主要是和be from/come from构成特殊疑问句。如：
Where are you from？/Where do you come from?
你来自哪里？
【注意】在此句型中，若句中有be动词时，就不能用任何助动词；但当句中是实义动词come时，其疑问句和否定句都要借助助动词do或does来完成。
三、形容词的用法
形容词修饰名词，用以说明事物或人的性质或特征，是英语中最常见的词性之一，通常在句中作定语、表语等。
1．形容词作定语，用于修饰名词或代词one, ones等，位于名词或代词之前，但若修饰不定代词要放在不定代词之后。如：
I want some big ones.
我想要些大的。
There is something interesting in today's newspaper.
今天的报纸上有些有趣的内容。
2．形容词作表语，放在连系动词(be/look/feel/sound等)后，构成系表结构，即“连系动词＋表语”，说明主语的性质、状态等。如：
You look great today.
你今天看起来很棒。
3．一些形容词和定冠词the连用，表示一类人或事物，相当于一个名词；另外，形容词前可用very, too, a little等表示程度的词修饰。如：
He often helps the old.
他经常帮助老人。

You are too lazy.
