七、[跨学科]阅读理解
Do a science experiment to see how rain forms. You will need: a glass jar (罐), hot water, a plate and ice cubes (冰块).
What happens in the jar
Hot water makes warm, wet air called steam (水蒸气). Steam rises up to the cold plate. The cold air near the plate changes the steam into water . Then, heavy drops of water fall.
What happens in the sky
The sun heats the water. The warm, wet air rises up into the sky. If the warm, wet air meets the cold air, rain clouds will form. When the clouds have enough water , the drops fall onto the ground as rain.
( )1. Which of the following is the right order of using the objects in the experiment
A. Ice cubes → A plate → A jar, hot water.
B. A jar, hot water → Ice cubes → A plate.
C. A jar, hot water → A plate → Ice cubes.
D. Ice cubes → A jar, hot water → A plate.
【点拨】细节理解题。根据“Pour 200ml of hot water into the jar.”，“Cover the jar with a plate. Wait 5 minutes.”，“Put ice cubes on the plate. Wait 15 minutes.” 和 “Watch for drops of water to fall like rain!”可知，实验时，先往罐子里倒入200 毫升热水；用一个盘子盖住罐子，等待5 分钟；把冰块放在盘子上，再等15 分钟；然后就可以观察到水滴像雨一样落下。故选C。
C
返回
( )2. How long does it take to see raindrops in this experiment
A. About five minutes. B. About ten minutes.
C. About fifteen minutes. D. About twenty minutes.
【点拨】细节理解题。根据“Cover the jar with a plate. Wait 5 minutes.” 和“Put ice cubes on the plate. Wait 15 minutes.”可知，实验观察到雨滴需等待约20 分钟。故选D。
D
返回
( )3. From the passage we can know the drops of water in the experiment come from ______.
A. the melting ice cubes B. the warm, wet air
C. the rain clouds D. the cold air
【点拨】细节理解题。根据“Hot water makes warm, wet... Then, heavy drops of water fall.”可知，热水会产生温暖潮湿的空气，即水蒸气；水蒸气上升至冰冷的盘子；盘子附近的冷空气使水蒸气变成水；然后沉甸甸的水滴就落下来了。也就是说，水滴是由温暖潮湿的空气产生的。故选B。
B
返回
( )4. Which of the following should be put into “ ▲ ”
A. wet air B. hot wind
C. rain clouds D. water drops
【点拨】推理判断题。根据“If the warm, wet air meets the cold air, rain clouds will form.”可知，如果温暖潮湿的空气遇到冷空气，就会形成“雨云”。故选C。
C
返回
( )5. In which class will you probably do this experiment
A. The history class. B. The chemistry class.
C. The maths class. D. The physics class.
【点拨】推理判断题。本文主要介绍了人工造雨实验，并解释了雨水形成的物理过程，可以推断会在物理课上做这个实验。故选D。
