First, get a glass of water and a piece of white paper.
首先，拿来一杯水和一张白纸。
一些不可数名词变复数需借助一些量词，如本句中的a glass of water 和 a piece of paper,要表达复数概念，须在量词上体现，e.g. two glass of water, three pieces of paper.
e.g. I drink two cups of tea. 我喝了两杯茶
He has three pieces of bread. 他吃了三片面包。
【扩展】
不可数名词没有复数形式，如果表示“一个”的概念，可用单位词：
a piece of news / information / advice / bread / paper / meat / coal
a bottle of ink, a grain of rice ,

常考不可数名词：information, weather, news, advice, fun等。
Look at the pictures.

Next, take them near the window, into the sunlight.
First, get a glass of water and a piece of white paper.
Then, hold the glass of water above the paper.
