Question

17．Why do we like drinking water from plastic bottles？Some people think it is healthy and clean．Others drink bottled water because it's easy-you can carry it around with you．In hot countries，like Greece，we often buy bottles of cold water in the summer．
However，making lots of plastic is not a good idea for many reasons．First of all，we need a lot of oil for plastic products．We usually use oil as a source（资源） of energy．If we reduced the number of bottles we made，we wouldn't need so much oil．Plastic bottles also pollute the environment．If we recycled all our plastic bottles，we wouldn't need so much space for rubbish dumps．But in Greece，we don't recycle much of the plastic we use．In 2006，Greeks recycled only about 10% of plastic waste．The rest became rubbish on land and in rivers and seas．So next time you want to throw away a plastic bottle in the litter bin，stop and think．If you recycled it，you would help the environment．But what can you do when there isn't a recycling bin near you？Well，there are lots of useful ways that you can use your bottles again．For example，an empty bottle makes a great piggy bank for your pocket money，and if you cut a bottle in half，you will have a plant pot．Go green!You can make adifference．

Answer 1

分析 为什么我们喜欢饮用塑料瓶里的水？有些人认为它是健康的和干净的．其他饮用瓶装水，因为它很容易携带--你可以随身携带它．在炎热的国家，如希腊，我们经常在夏天买瓶装的冰水．
  然而，由于许多原因，制造大量的塑料不是一个好主意．首先，为了制造塑料制品我们需要大量的石油．我们通常把石油作为能源来用．如果我们减少我们制造的瓶子的数量，我们就不需要这么多的石油．塑料瓶也会污染环境．如果我们回收了所有的塑料瓶，我们就不需要那么多的空间给垃圾堆放场了．但在希腊，我们没有大量回收我们使用过的塑料制品．在2006年，希腊人只回收大约10%的塑料废弃物．其他的变成了陆地上的、河流和海洋里的垃圾．所以下次你想把一个塑料瓶扔在垃圾桶里，先停下来想一想．如果你回收了它，你就可以保护了环境．但是当你附近没有废物回收箱的时候你能做什么呢？有很多再利用你的瓶子有用的方法．例如，一个空瓶子可以做成一个大的储钱罐来储蓄你的零花钱．如果你把一个瓶子切成两半，就变成了一个花盆．生产或使用绿色产品！你会变得与众不同．

解答 46．答案：D．细节理解题．根据Some people think it is healthy and clean．Others drink bottled water because it's easy"可知关于瓶装水提到了"healthy and clean，easy"三项内容，而没有提到瓶装水 expensive（贵）．故选D．

48．答案：D．细节理解题．根据In 2006，Greeks recycled only about 10% of plastic waste．"可知在2006年，希腊人只回收了大约塑料废物的10%，所以有90%的成了垃圾．故选D．
49．答案：A．细节理解题．根据If you recycled it，you would help the environment．"可知如果你回收了使用过的塑料瓶，那你就帮着保护了环境．故选A．
50．答案：C．结构分析题．根据Go green！You can make a difference，可知作者倡议为绿色环保行动起来，本篇短文讲了废旧塑料很污染环境．最后作者倡议为绿色环保行动起来，你会起很大作用．也就是说为了环保，你可以做些事情．A．B．D．选项意思都不符合，故选C．

点评 这是一篇环保类短文阅读．短文从塑料的制作消耗了大量的能源，再到塑料瓶的处理，最后倡议为绿色环保都行动起来．应试生态环保类题目时，应在理解文章的基础上，要重点突破--归纳主旨大意技能，应观察全文的结构安排，理解文章浓墨重笔写的"重心"，考虑文章组织材料及支撑性细节是服务于什么的，分析故事的发展结局都是围绕什么中心大意来安排的．
