考点名称:there be 句型

  • There be句型:
    是英语中常用句型,意思是“有”,表示“人或事物的存在”。
    There在此结构中是引导词,已经没有副词“那里”的含义。
    There be后面的名词是句子的主语,属倒装结构。常用“There + be+名词+地点/时间状语”的结构。 

  • There be结构的用法
    A、肯定结构:
    There be句型的肯定结构表示“某处存在某物或某人”或“某时发生某事”。 
    a. There is+单数可数名词/不可数名词+地点/时间状语。 
    例:There is a cat under the chair. 椅子下面有一只猫。 
           There is some water in the bottle. 瓶子里有些水。 
    b. There are +复数名词+地点/时间状语。 
    例:There are some apples in the basket. 篮子里有一些苹果。
    B、否定结构:There be句型的否定结构是在谓语动词be的后面加“not (any)”或“no”. 
    例:There are no tables in the room. 或者There are not any tables in the room. 房间里没有桌子。
    C、疑问结构:There be句型变成疑问式时,要把there和谓语动词be的位置互换。 
    例:Is there a pen in the schoolbag? 书包里有一支笔吗?

  • Therebe结构和have的区别与联系:
    1.区别点:
    there be 意为存在,强调某地有某物,不表示所属关系;
    have 表示所有关系, 强调某人或某地有某物,这是其基本用法。如:
    There are some trees in front of the house.房前有些树。
    Tom has many friends in China.汤姆在中国有许多朋友。

    2.相同点:
    在表示结构上的含有时,既可以用there be 句型,也可以用have(has) 来表示。如:
    中国有许多长河。
    There are many long rivers in China.
    China has many long rivers.
    三月份有多少天?
    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?
