Step 4　问题探究
1．There be句型的一般将来时
(1)在人们的家里将会有机器人。
There__will__be__robots__in__people's__homes.
(2)明天不会有一个会议。
There__won't__be__a__meeting__tomorrow.
(3)一百年后将会有更少的污染吗？是的，会有。/不，不会有。
Will__there__be__less__pollution__in__one__hundred__years？Yes，there__will./No，there__won't.
There be句型的一般将来时的构成：
肯定句：There will be＋名词＋其他成分。
【温馨提示】无论后面是单数名词还是复数形式，be都必须用原形。
否定句：在will后面加not；一般疑问句：把will提到there之前，回答：Yes，there__will./No，there__won't__to．
2．few，a few，little，a little，much，many
(1)几乎没有朋友few__friends
(2)一些朋友a__few__friends
(3)几乎没有水little__water
(4)一点水a__little__water
(5)许多水much__water
(6)许多学生many__students
few和a few修饰或代替可数名词，few表示否定意义，a few表示肯定意义；little和a little修饰或代替不可数名词；little表示否定意义，a little表示肯定意义。
可数名词和不可数名词前都可用some，any，a lot of，lots of等修饰。可数名词表示不确定数量时，用a few，few，many修饰，询问数量时用How__many；不可数名词表示不确定数量时，用a little，little，much修饰，询问数量时，用How__much。
3．more，less，fewer的用法
(1)史密斯先生想挣更多的钱。
Mr.Smith__wants__to__make__more__money.
(2)那个杯子里的水更少。
There__is__less__water__in__that__glass.
(3)在那所学校里我有较少的朋友。
I__have__fewer__friends__in__that__school.
more是many和much的比较级，其后既可以跟可数名词复数，也可以跟不可数名词，意思是“更多”。
less是little的比较级，其后只接不可数名词，意思是“更少的，较少的”。
fewer是few的比较级，其后只接可数名词的复数形式，意思是“更少的，较少的”。
