举例
Water can be a liquid ,a solid or a gas .When it is a solid, it may be as hard as rock(岩石) .When it is a liquid, you can pour (倒) it out of a container(容器) .When it is a gas, you cannot see it or feel it. When water changes to water vapour ,we say that it evaporates(蒸发) .When water vapour changes to water ,we say that it condenses(凝结) .
Water can change from one form, to another easily. This is why we always have fresh supply (供给) of water .Now let us find out how this is possible. The heat of the sun evaporates water, from the oceans(海洋), seas, rivers and lakes. The heat also evaporates water from the ground and from plants and animals. Water vapour is formed. This rises and forms clouds in the air.
When the clouds come near a mountain, they are forced to rise. As the clouds rise, they are cooled. The higher they rise, the more they are cooled. This causes (引起) more and more water vapour to condense . In this way, the tiny(微小) drops of water in the clouds get bigger and bigger until they are heavy enough to fall to the earth as rain .
Some rain water which fails on the earth is again evaporated by the sun's heat. Some of it sinks into the ground. It may be used up by thirsty plants. It may reach a well (水井) or a spring(泉) . Most of the water goes back to the rivers, seas and oceans. This process(过程) then starts all over again . This process is called the water cycle.
Questions:
1) How many forms does water have?
A) Only one B)Two C)Three D)Four
2) Which of the followings shows the wafer condenses?
A) A liquid changes to a solid B)A solid changes into a gas
C) A gas changes to liquid D)A solid is heated
3)The tiny drops of water are called rain when .
A) water vapour condenses B)water vapour forms clouds
C) they are in the clouds D)they are big enough to fall to the earth
4) The rain wafer that sinks into the ground is than as that goes back to the rivers, seas and oceans.
A)more B)less C)the same D)as much
【答案解析】
1) C 开篇第一句就给出了水的动态形式
2) C 由 “when water vapour changes to water we say that it condenses”这一句得出，但要搞清“gas”与“vapour”，“ water”与 “liquid”的对应关系。
3) D 第三段最后一句“”until they are heavy enough……”可知
4) B 最后一段“some of it sinks…”“most of the water goes back”两句，对此“some”与“most”的量的区别，不难得出。
【趋势预测】本篇阅读材料是一篇纯科普性的物理知识，里面的专业术语比较多，这正是中考题中逐渐尝试使用的一种考查方法。但专业术语，有绝大部分可以在上下文中语境暗示中找到较为合理的解释。本篇文章讲述了“水循环”这一物理知识，学生们对此基本有了自己的认识，理解起来应该不太难。
【解题关键】
本文介绍了水的三种变化：固态、液态、气态。第一段介绍了三态形式以及相互的变化。第二段介绍了海水因为太阳加热变成水蒸气进而形成云。下一段介绍了雨的形成。最后介绍了地面上的雨的不同的用途。
解决此种类型题目时需注意两点：①没必要也不可能将术语全部翻译出来，只要用“记号”的形式界定他们之间的区别即可，如“liquid、solid、gas、vapour等②时刻留念上下文的相互补充释义，尽可能地找到这些术语的定义，哪怕是一些朴素或不精确的解读。
