Question

6．Nowadays a new lifestyle called low carbon life（低碳生活）is spreading every corner of our country．The meanings of low carbon are low energy and no waste．It is such an important project that I can't wait to express my ideas about it more clearly．
In the first place，we should have a no-car day every week in our school．Because cars not only cause serious air pollution but also waste energy．On no-car day，neither students nor teachers are allowed to drive to school．Meanwh ile，just walk，jump，cycle or run．Use our legs and enjoy the fun．
In the second place，we had better not use plastic bags any more．No one can bear the"white pollution"．So，it is wise to use bags which can be reused again and again．
Finally，one thing that we should keep in mind：every big thing comes from the subtle．Therefore，as students，we ought to turn off the lights the moment we leave，turn off the water tap in time，and reuse our textbooks and so on．
In one word，it is necessary for all of us to put the low carbon lifestyle into our daily life．Just remember these：no-car day，no plastic bags，and no waste．Let's do it now．

Answer 1

分析 本文主要讲了低碳生活的含义，和作者对低碳生活的观点，每周有一天不开车，不用一次性塑料袋，不浪费．

解答 46．D； 细节题，根据与原文句子The meanings of low carbon are low energy and no waste．低碳的意思是低能量和不浪费．所以选D．
47．C；内容理解题，根据第二段内容，在不开车日里，老师和学生都不能开车去学生，所以"没有人"开车去学校，故选C．
48．D；词语大意推测题，由后面句子讲到离开时关灯，及时关水龙头，再次使用我们的教科书，都属于小事情，故推测划线的单词含义为small things，故选D
49．C；推理题，根据短文句子as students，we ought to turn off the lights the moment we leave…作为学生，我们应离开时关灯，推测作者是一名学生，故选C．
50．A；细节题，根据短文第三段内容，说我们最好不再使用一次性塑料袋，所以A项中说Michelle 总是使用一次性东西然后扔掉，是不符合低碳生活的行为，故选A．

点评 阅读理解题通常从细节，文章主旨，推测词组大意几个方面考查学生对文章的理解，做题时注意找到文章出处，做到有理有据．
