all right =OK
Mother: Look!

look 看 （动作） look at ... see 看见（结果）
There’s = there is
be动词包括am,is,are .
there be句型表示人或物的存在
an ice cream man
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 are two shirts on the bed.
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be动词提前，否定句就在be后面加not就可以了。
另外记住some用于可数名词单数及不可数名词，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, 复数主语要用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。
practice
请你变换刚才的三个句型，分别改成一般疑问句以及否定句。
There is a tie in the box.
There are two shirts on the bed.
There is some water on the desk.
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。
There is a pen, two pencils and some books on the desk. 书桌上有一支钢笔、两支铅笔和一些书。
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）
