①一般是在be动词或情态动词后加not。
Mary was at school yesterday. —> Mary was not at school yesterday. I can make a model plane. —>I can not make a model plane.

Mary was at school yesterday. —> Was Mary at school yesterday? I can make a model plane. —> Can you make a model plane?
②不含be动词或情态动词的句子，借助助动词开头，动词还原成原形。 He likes drawing pictures.—>Does he like drawing pictures.
I went to the park yesterday. —>Did you go to the park yesterday?
2、疑问句
用来提出问题，询问情况的句子，末尾用问号。
1）一般疑问句：一般疑问句常用来询问一件事是否属实，通常以be动词，助动词或情态动词开头，用yes或no来回答，因此又叫是非疑问句，通常读升调。
—Is Mr Green from the UK? —Yes，he is. / No，he isn?t. —Do you have any hobbies? —Yes，I do. / No，I don?t. —Can you play the guitar? —Yes，I can. / No，I can?t.

3）选择疑问句：提供两种或两种以上情况，让对方选择，往往用or连接。 —Would you like some tea or coffee? —Some coffee, please.

表达喜怒哀乐等强烈感情，句尾常用感叹号（!），语气用降调。 1）what + 名词或名词性短语 What a big garden (it is)!
What an interesting storybook (it is) ! What lovely weather (it is)! What pretty girls (they are)!
2）how +形容词或副词＋主语＋动词 How nice!
How beautiful the flowers are! How tall Yao Ming is!
5、there be 句型 表示在某地有某人或某物。
1）主语是单数，be动词用is(was)；主语是复数，be动词用are(were)。 There is some milk in the fridge.
There are some peaches in the basket.
2）如果有几个不同的人或物并列存在，be动词根据最靠近的那个名词而定。 There is a ruler and five knives in the pencil case. There are five knives and a ruler in the pencil case.
3）there be句型和have/has区别：
there be句型表示某地有某人或某物；
have/has表示某人有某物。has用于第三人称单数，其余人称和数用have。 There are some English books on the desk. I have some English books.
