The way to see water's temperature Here's how to tell whether a glass contains（容纳）hot water or cold water-without ever touching it！
You'll need 2 drinking glasses that are exactly alike Ice cubes（块） Adult helper Bathtub（浴缸）or shower Pencil and paper	1.Fill one glass with cold tap water and cool it with ice cubes. Don't use a lot of ice; just cool it a little. 2.Fill the other glass with very hot water. 3.Pour both glasses out into the tub at the same tirme and speed. Repeat this process（过程）a fewtimes，and watch closely each time. 4.Ask your helper to fill the glasses again and not tell you which is which. When you see the water splash in the tub.guess which one is the hot water. 5. Repeat several times. Keep score on your paper. You should be able to guess correctly more than half the time.
Cold water is more dense（稠密的）than hot water.so a cup of cold water is just a little bit heavier than a cup of hot water.		When you pour hot water onto a hard surface，it splashes（溅起）around more than the cold water because it's less dense. SOURCE:TNS

【解析】

本文是一篇科普阅读，介绍了在不接触的情况下如何分辨一个玻璃杯里是含有热水还是冷水的方法。

【1】推理判断题。根据The way to see water's temperature．Here's how to tell whether a glass contains （容纳） hot water or cold water - without ever touching it!看水温的方法。下面是如何分辨一个玻璃杯里是含有热水还是冷水的方法-永远不要触摸它！可以推测出，我们可以在"科学海报"上看到这样的图片。故选D。

【2】细节理解题。Here's how to tell whether a glass contains （容纳） hot water or cold water - without ever touching it!这是如何分辨一个玻璃杯是含有热水还是冷水，而不必碰它！结合选项可知，你不用碰水就可以发现水是冷的还是热的。故选D。

【3】推理判断题。根据Pour both glasses out into the tub at the same time and speed．Repeat this process（过程） a few times,and watch closely each time.将两个玻璃杯同时快速倒入浴缸．重复这个过程几次。仔细观察每一个时间。结合文章内容可以推测出，根据图片可知，看温度的方法是"通过观察"。故选A。
