Key point
• 1.不管作主语的名词有多少个，be动词的数只与 第一个名词保持一致。这就是传说中的就近原则。 • 如：There is a pen, two pencils and some books on the desk. 书桌上有一枝钢笔、两枝铅笔和一 些书。 • 2. there be和have(has)都是“有”，但它们的 含义却是不同的。there be表示“客观存在”， 而have(has)表示“拥有、占有”。例如： • There is a watch on the desk. 书桌上有一块手 表。（表示存在） • I have a watch. 我有一块手表。（表示拥有）
Children: Yes, we are, thank you!
肯定回答：Yes, we are. 否定回答：No, we aren’t.
woman [‘wumən] man [mæ n]

Mother: Two ice creams please. • ice cream 可数名词,复数形式是 ice creams • give us two ice creams 给我们两个冰淇淋
Mother: Here you are, children. Children: Thanks, Mum.
There be 句型变换
• 如果一个句子中有be的形式存在，那么这 个句子的疑问或否定形式都在be本身变化， 比如一般疑问句，只要把系动词提前，否 定句就在be后面加not就可以了。另外记住 some用于可数名词，并且用于肯定句中。 Any用于不可数名词，并且用于否定句和疑 问句。
口诀
• There be句型不一般，主语跟在be后边。 • be可变为is / are, there永远不变化， • 单数主语用is, 复数主语它用are。 • 变疑问，很简单，be须大写来提前； • 变否定，也轻松，be后not记心中； • 肯定句中用some, 否定、疑问any用。 • 时间／地点是状语，句子首尾任你选。
• 复数：There are some ice cream men.
There be 句型的结构： 1）There is + 可数名词单数/不可数名词 + 介词短语. 2）There are + 可数名词复数 + 介词短语. 介词短语= 介词 + 名词 介词包括：in (在…里面), on (在…上面)… 例句： There is a bottle on the table. There is some water in the glass. There are two shirts on the bed.
