there be 结构 一、定义 There be 结构又叫存在句，表示“在某地存在某物”。 注意：there be结构表示“存在有……”，即某处有某物；have表示“某人拥有某物”，即所属关系。 二、结构 1. 肯定句 ①there is+可数名词单数/不可数名词+其他。 There is a book on the desk. There is some water in the bottle. ②There are+可数名词复数+其他。 There are many flowers in the garden. 2. 否定句 在be动词后面加not，表示“没有”。 There are some students in the classroom. →There aren’t any students in the classroom. 3. 一般疑问句 There be结构变成一般疑问句，要把be提前，构成“Be+there+...”的形式。 肯定回答：Yes, there+be. 否定回答：No, there+be+not. (能缩写就缩写) There is a book on the desk. →Is there a book on the desk 肯定回答：Yes, there is. 否定回答：No, there isn’t. 注意： 1. There be句型可以用于不同时态，因此不同的时态be动词会有不同的形式；在变否定句和疑问句时，要将some变成any。 There are some apples in the fridge. →There aren’t any apples in the fridge. →Are there any apples in the fridge 2. 当there be 结构的主语是两个或两个以上的名词时，be动词要与它最近的名词保持一致（就近原则）。 There is an apple and two grapes on the table. There are two grapes and an apple on the table. 我们一起练一练 一、用be动词的正确形式填空。 1. There_____ some books on the desk. 2. There _____ some tea in the cup. 3.
