How many days are there in March?
How many days has March?
A、there be 结构中的谓语动词be在人称和数上应与其后的主语保持一致。主语是不可数名词或单数可数名词时用is,是复数时用are。
例:There is a flower in the bottle. 瓶里有一朵花。
There is some money in the purse. 钱包里有些钱。
B、若句子中有几个并列的主语时,be的形式要与离其最近的一个主语在人称和数上保持一致。
例:There is a boy, a girl and two women in the house. 房子里有一个男孩,一个女孩和两个妇女。
There are ten students and a teacher in the office. 办公室里有十个学生和一个教师。
There be结构的句型转换:
A、否定句:
there be的否定式通常在be后加not构成(在口语中be时常与not缩写在一起)。如果句中有some,一般要变成any。 例:
There are some children in the picture.
There aren't any children in the picture.
B、一般疑问句及其答语:
把be提到there前,首字母大写,句末用问号即可。其肯定答语是Yes, there is / are;否定答语为No, there isn't / aren't。 例:
— Are there two cats in the tree?
— Yes, there are. (No, there aren't.)
C、特殊疑问句及其回答
a. 提问句子的主语(包括主语前的修饰语)时,句型一律用“what is+地点介词短语?”(无论主语是单数还是复数都用is)。
例:There are some birds in the tree. → What's in the tree?
b. 就there be后面的地点状语进行提问时,句型用“where is/ are+主语?”
例:There is a car in the street. → Where is the car?
c. 提问可数名词(主语)前的数量时,用how many,句型结构为“how many+ 复数名词+are there+其它)”(主语无论是单数还是复数,be通常要用are)。
例:There are three books on the desk. → How many books are there on the desk?
