2.数数法:篮球等可以一个,两个数出来的是可数名词空

气等不能一个,两个数出来的是不可数名词

3.一分为二法:一个事物一分为二后如果不再具有原来的形态,则是可数名词,如桌子

一个事物一分为二后如果还具有原来的形态,则是不可数名词,如肉,纸

Peachcoffeeinkshirtpicturesistergardensofaknifesnowwatericetea

否定句的构成:There+be+not+名词+其他。

一般疑问句的构成:Be+there+名词+其他?

Thereisaboyandfivegirlsintheroom.

Therearefivegirlsandaboy.

★用thereis还是thereare,取决于紧跟在be动词后面的名词是单数还是复数

注意:虽然是“有’的含义,但不能用“therehave/has”

EX:根据句意,用适当的be动词填空,补全句子

bookandtwopensonthedesk.
