How many days are there in March?
How many days has March?

  • There be结构中的be动词的确定:
    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?
