Unit2 Topic2Section A(康康、玛利亚和简正在房间里谈话，,外面的风刮得很厉害。
)多么糟糕的天气!风太大了！沙子的确刮得脸很疼。
刚才在街上走时，我什么也看不见。
对此我很难过。
但是是什么引起这些沙尘暴的呢?人们乱砍滥伐。
结果，大量肥沃的土地变成了荒漠。
那太糟糕了，但是那怎么能影响天气呢？树木可以防风固土。
并且森林可以贮存大量的水分。
树木也能防止水土流失。
砍伐树木对人类、动植物都有害。
尽管我们已经建起了“绿色长城”,我们仍需要采取措施保护环境。
Section B康康，读这篇文章。
关于什么的？关于中国的空气污染问题。
它提到中国已成为世界上最大的煤炭生产国和消费国。
结果，空气污染成已成为一个严重的问题。
是的，但是政府为了保护环境正在采取有效的措施。
那样很好。
没有人喜欢污染。
我们不应该到处丢弃垃圾。
不要在公共场合随地吐痰。
不要践踏草坪或采摘花朵。
每个人都应当保护野生动物并且多种一些树木。
对。
我们应尽一切努力保护环境。
Section C地球已有46亿年了。
我们人类生活在地球上只有三万五千年，但是在此期间我们在许多方面改变了我们的星球。
我们所做的一些事情对地球有益，然而其他一些对地球却有负面影响。
在全世界，人们已经砍掉了数百万的树木。
下雨或吹风时，土壤被带走，森林变成了荒漠，因此许多种类的动植物正在灭绝。
在大城市，小车和公交车污染了空气，现在城市里许多人都有健康问题。
工厂也污染了土地和水。
结果，现在许多河流和湖泊失去了生机。
地球周围有一种特殊的氧气叫做“臭氧”(O3)，它对地球很重要。
但现在空气污染正在破坏它，而且使臭氧层出现了一个非常大的洞。
大量来自太阳的有害射线穿过这个洞直接进入地球大气层。
这是非常危险的，因为这种射线能导致癌症。
空气中的二氧化碳(CO2)大量增多。
二氧化碳主要来自燃烧的油、煤和木柴。
它在地球周围形成毯子式的覆盖层。
来自太阳的热量不能散发，所以气温度升高。
这就是所谓的“温室效应”。
