Karen: I know.
I must go to the supermarket.
Let's make a shopping listThe weekend shoppingI must go…不可回避的义务。to the supermarket, “to”介词，后面接宾语。 There isn’t表示“没有，不存在”。Sugar不可数，所以用单数isn’t。 any sugar是不定量的，在否定句后面加any,不用 some.Lucy: Ok.
How much sugar
do we need?
Karen: Two bags.
Lucy: Two bags of sugar…two bags of…数字+可数度量单位+of+不可数名词,表示不可数名词量的多少Watch and anser:Lucy: We need some
tea, too, Mum.
There isn’t much tea
in the tin.
Karen: Let’s get four
packets.
Lucy: Four packets
of tea...much+不可数名词用于否定句和疑问句。在肯定句中，我们说a lot of tea in the tin。
We have much tea.（此句错误）Lucy: What about food for the
weekend,Mum?
Karen: We need a loaf of bread, some
meat for Sunday lunch, and
some vegetables, too.
What vegetables do we want, Lucy?bread不可数，为了表示“多少”，要说a loaf of bread ,不是a/one bread。loaf复数为loaves, 和 knife/knives同。Lucy: One loaf of bread, a piece of meat,
some vegetables…Mum, these things
are all really boring. What about some nice things for the weekend?
Karen: What kind of things?
Lucy: Well, chocolate,and
ice cream, perhaps…
What about… 后面用some,没用 any，实际上表示提议，希望得到“yes”回答Karen: You’re right.
Let’s get a box of
chocolates. Some
ice cream for you
and the boys, and a
bottle of wine for me
and your father!不可数名词数量的表达法：
不可数名词前不加a/an，后不加s；
但可通过改变量词形式的方法来表示不可数名词的量，量词可数。 a bottle of water---two bottles of water
a piece of bread---three pieces of bread表示不可数名词量的相关词语还有：some,
a lot of , much, a little , little, lots of……巩固练习:
