PAGE 7 there be句型 there be句型：? 表示存在，即：“某处有某物（或人）”或“某时有某事”。句型基本结构：? There is + 可数名词单数 或 不可数名词 + 时间或地点。There are + 可数名词复数 + 地点1、在there be 句型中，主语是单数，be 动词用is ; 主语是复数，be 动词用are ; 如有几件物品，be 动词根据最接近be 动词的那个名词决定。?例如： （1）There is a pen on the desk . (2)There are two books on the desk. (3)There is a pen and two books on the desk. (4)There are two books and a pen on the desk. 2、there be 句型的否定句在be 动词后加not , 一般疑问句把be 动词调到句首。例如： （1）否定句：There is not a box on the table. 疑问句：Is there a cat in the room? (2)?否定句：there are not any oranges in the box. 疑问句：Are there any oranges in the box? 3、some 和any 在there be 句型中的运用：some 用于肯定句， any 用于否定句或疑问句。?例如： （1）There are some rulers in the pencil-box. (2)There are not any rulers in the pencil-box. (3)Are there any rulers in the pencil-box? 4、and 和or 在there be句型中的运用：and 用于肯定句， or 用于否定句或疑问句。?例如： （1）There is a boy and a girl in the classroom.（肯定句） (2) There aren’t any books or pencil on the desk.（否定句） (3) Are there any chair or stools in the house?（疑问句） 5、针对数量提问的特殊疑问句的基本结构是： How many + 名词复数 + are there + 介词短语？ How much + 不可数名词 + is there + 介词短语？? How many books are there in your bag? How much water in your glass? 6、针对主语提问的特殊疑问句的基本结构是： What’s + 介词短语？? There is a pen on the desk. What is on the desk? 二、there be句型与have(has) 的区别： 1.there be 表示在某地有某物（或人）；have(has) 表示某人拥有某物。? （1）There is a dog in the box .箱子里有条狗 （2）I have a pen .我有一支铅笔。 2．在there be 句型中，主语是单数，be 动词用is ; 主语是复数，be 动词用are ; 如有几件物品，be 动词根据最接近be 动词的那个名词决定。在句子中含有have/has的句型中，究竟是选用have还是has，则由主语的人称词来决定。例如： （1）I have a dog and a cat.我有一条狗和一只猫 (2)She has two rabbits.她有两只兔子。 课堂练习 一．用恰当的be（am, is ,are）动词填空。 There_______ many apples in the box.
