试一试: Amina: What is on the table? Wei: ___ and six eggs. 选出合适的形式。 (Two breads / A bread / Some bread) 答案: Some bread — 面包不是一个一个数的，所以不加 a，也不加 -s：Some bread。Two breads 加了数字和 -s，A bread 在前面加了 a，而 bread 两样都不能加。
要记住的常见词
有几个日常用词不能一个一个数，哪怕感觉上好像可以。把这五个一起记住：money、bread、water、milk、coffee。在咖啡馆你也会听到 a coffee 或 two coffees，那里指的是几杯咖啡。
I drink water every day.
There is milk in the fridge.
He makes coffee in the morning.
试一试: Farid: Can you pay for the bus? Yasmin: Yes. I have ___ in my bag. 选出合适的形式。 (a money / some money / two moneys) 答案: some money — money 是上一张卡片里那五个词之一，所以不加 a，也不加 -s：some money。
用容器来数
那水要怎么数呢？数装它的东西。这时数字数的是容器，所以加复数词尾的是容器这个词：two glasses of water。
a cup of coffee, two cups of coffee
a glass of milk, two glasses of milk
a bottle of water, two bottles of water
试一试: Camila puts ___ on the table for her cooking class. (two glass of water / two glass of waters / two glasses of water) 答案: two glasses of water — 数字数的是容器，所以加复数词尾的是容器这个词：two glasses of water。另外两个选项，一个漏了词尾，一个把词尾加错了词。
试一试: Lani: What do we need for dinner? Diego: ___ and a bottle of water. 选出合适的形式。 (Two breads / Two eggs / A bread) 答案: Two eggs — 这一题关键看是哪个词。鸡蛋是一个一个数的，所以数字直接放在前面：Two eggs。面包不是，所以它不能加数字，不能加 -s，也不能加 a：Two breads 和 A bread 都不对。
