17.To understand why the Earth is warming up,first of all,we need to understand why it is warm.Our planet is covered with atmosphere (大气).Sunlight passes through the atmosphere and reaches the Earth.The Sun heats up the Earth's surface.When the heat rises into the air,it is stopped by some special gases (气体)in the atmosphere like GOz,the heat returns to the Earth and keeps it warm.Power stations and cars release (释放)so many greenhouse gases every day.So we can help stop global (全球的)warming by using less electric things such as turning off lights when we leave a room,asking our parents to turn down the heating in our house to save energy.We can also stop global warming by finding other ways of transportation.For example,ride a bicycle or walk instead of going by car,Another way to help stop global warming is to plant and care for trees.Because trees take in C02,they are our best friends when fighting against global warming.
The problem of global warming cannot be solved in a day.It may take a long time to find clean energy,such as wind energy.It may take a long time to plant the trees again we are cutting down.But every little thing each person can do to save energy and our forests will help.Think about our planet.Think about ways we can help make the Earth a safe and comfortable place for the future.

分析 【文章主旨】这是一篇有关环保的阅读,短文主要讲述的是大气变暖这一方面,先说明了造成的原因,比如发电厂和汽车每天释放很多温室气体.然后重点讲述如何阻止地球温度再次上升,其中还例举了几点具体做法,比如减少使用电器,换一种交通工具等.
解答 37 B 推理判断题.根据文中第一段中的the heat returns to the Earth and keeps it warm.热量就会重返地球并使之变暖.可知it指代的是前面所提及的 the Earth,故选B.
38 B 细节理解题.根据题干要求结合文中的第二段内容可知,阻止全球变暖的方法有:第一 by using less electric things such as turning off lights 通过减少使用用电器比如关灯;asking our parents to turn down the heating in our house to save energy.可以让我们的父母把家里的暖气关掉来节约用电;第二We can also stop global warming by finding other ways of transportation我们可以通过换一种交通工具来阻止全球变暖;第三 plant and care for trees植树和保护树木.综上可得共有三种方法,故选B.
39 B 推理判断题.根据文中最后一段中的The problem of global warming cannot be solved in a day全球变暖这个问题不能只用一天时间解决.再结合题中的B选项:全球变暖这个问题不能解决,可知两者说法有出入,故选B.
40 C 主旨大意题.纵观全文,可知短文首先讲了造成全球变暖的原因,然后重点讲述如何阻止地球温度再次上升,其中还例举了几点具体做法,比如植树和保护树木,开发新能源等.所以文章主旨是我们要如何制止全球继续变暖.故选C.
点评 首先要仔细阅读文章,掌握大意,然后结合具体的题目再读短文,从中找出相关的信息,就可以确定正确答案.
