不可数名词(chocolate/advice)

可数名词和不可数名词要注意:
可数名词有单复数,不可数名词没有
单数可数名词表泛指,用a/an修饰,表特指用 the修饰;不可数名词不能用a/an修饰
可数名词,不可数名词都可用some/any/a lot of/lots of 等修饰,many/few/a few 修饰可数; much/little/a little 修饰不可数
可数名词前可用基数词修饰,不可数名词前用
(piece/pair) +of 表示数量
可数名词做主语,谓语动词单复数要一致
对可数名词提问用how many;对不可数名词提 问用 how much
重点短语:
Have problems with sth/sb 在某事方面有困难 Be afraid to do sth 害怕做某事
Cut sth in half 把某物切成两半
语法:条件句
1) 主句will+ do构成(一般将来时),从句一 般现在时(if后面紧跟从句);即'主将从现'

2) 主句由should+ do构成,从句一般现在时
If you are ill, you should go to see a doctor.
