Step2:语法
.特殊疑问句特殊疑问句:是指以特殊疑问词开头,对陈述句中的某一特定部分进行提问的句子。
1.特殊疑问句的回答:特殊疑问句不能用yesno来回答,要根据实际情况来回答。如 How many people are there in your   family?  —There are five.                                                             
 
2 .特殊疑问句的语序:
1) 当特殊疑问词指代的内容是句子的主语时,则:特殊疑问词+陈述语序。如:What makes it better?
2) 当特殊疑问词指代的内容不是句子的主语时,则:特殊疑问词+be动词/助动词+主语+实义动词。 如:Why do you like it?
3.特殊疑问词

      什么职业、什么事情等。
Who 表示人,意为               Whose 意为某人的……”
Where意为在哪里,询问地点。      When—意为什么时候,询问时间Which意为哪一个;哪些,可以表示  人,也可以表示物。

how tall   多高              how many   多少

how much    多少
4.Work out the rule
1). We can make Wh-questions with Wh-words and the verb to be
  (e.g. am, is  and are.)
2). We use   do or  does  to make Wh-questions with other verbs.
(1). –What   is her name?  -Anna.
(2). --Where   is she from?  -Germany.
(3). –Who   are your friends? -Ben and Judy.
(4). –How old are they?  -Twelve and thirteen.

(8). --What colour does she like? -Red.
(9). --How many   e-friends does he have? –Five
二.The articles (冠词).
解析:冠词是用在名词前面,帮助说明
名词所指的人或事物是泛指还是特指的词。
冠词分不定冠词(The Indefinite Article)和定冠词(The Definite Article)两种。
a / an 是不定冠词 ,仅用在单数可数名词前面,表示的意义。它可以表示数量“一”,也可以表示一类人或事物。a用在以辅音(指辅音音素)开头的词前, an用在以元音(指元素音素)开头的词前,如: a boy, an hour
__ ___ boy               _____ teacher
_____ computer       _____ unit
_____ football team _____ violin
_____ apple           _____ ice cream
_____ egg             _____ old book
_____ hour            _____ umbrella
