　　C.why droughts occur more in dry climates D.how human activity affects our water supply

　　答案解析解析关闭主旨大意题。第一段的第一句就是主题所在:使用太多的水或者把垃圾扔到河里是人类可能让水供给处于危险的明显方式,但我们也以不明显的方式影响着我们的水供给。后面的篇幅主要围绕人类如何影响水资源展开的。故选D项。

　　答案解析关闭 D

　　-*- A B 1.Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger,but we also affect our water supply in less obvious ways.使用太多的水或者把垃圾扔到河里是人类可能让水供给处于危险的明显方式,但我们也以不明显的方式影响着我们的水供给。点拨:put...in danger意为“使……处于危险之中”。 -*- A B 2.The more roads and parking lots we pave,the less water can flow into the ground to become groundwater.我们铺砌的道路和停车场越多,能流入地面而成为地下水的水就越少。点拨:“the+比较级,the+比较级”表示“越……,就越……”。 3.Thinking about the way we use water every day can make a big difference,too.考虑我们每天用水的方式也能产生很大的影响。点拨:句中thinking about the way为动词-ing形式做句子的主语,而we use water every day为the way的定语。make a big difference意为“产生很大的影响”。 -*- A B 4.You can take steps to save water in your home.你可以在家采取措施来节约用水。点拨:take steps意为“采取措施”,也可用take action或take measures来表示,to save water为动词不定式做目的状语。take steps to do sth.是写环保类话题作文时常用的结构。 -*- 假如你是李华。最近,为了保护环境,你校学生会组织开展了“构建低碳校园”活动。你的美国朋友David知道这一情况后很感兴趣,发邮件向你了解具体情况。请你根据以下提示给他回一封电子邮件: 1.日常出行时如何减少碳排放; 2.在餐厅就餐时如何节约粮食; 3.在寝室和教室如何节约水、电等。注意:1.词数100左右; 2.可以适当增加细节,以使行文连贯。 -*- Dear David, In your last email,you showed great interest in “Building a low-carbon campus”,which aims at protecting the environment.Now I’ll tell you something about it in detail. First of all,we advocate walking or riding bikes instead of driving a car.Secondly,we consume less meat,choosing green food.In the school canteen,anyone caught not eating up what is bought will be punished.Thirdly,we should not leave the lights on in the daytime and leave water running after washing. -*- In a word,building a low-carbon campus is not an easy thing.We are sparing no effort to do every little thing to achieve the goal,though. Yours, Li Hua
