Answer 1

分析 文章大意：
文中提到的是如何节能．在日常生活中，为了节约能源，减少污染，我们能做的有很多．比如拼车，可以有效减少碳排放；再比如改变一些小的生活习惯，比如随手关灯，换用节能灯等，都可以有效减少电能的消耗．

解答 50．C，考察副词辨析及上下文理解，文中提到"Carpooling is the sharing of car journeys in order that more than one person travels in a car"拼车是指好多人乘坐同一辆车，这样做的一个直接结果就是碳排放量减半，immediately译为直接地，马上，由此确定选择C．
51．B，考察动词辨析及上下文理解，文中提到"You can do a lot of things inside and around your home"在你房子周边及内部你应该尽量做很多事情，这样会帮助你…既然是帮助你，应该是减少污染及节约金钱，help sb do sth译为帮助某人做某事，由此确定选择B．
52．A，考察形容词辨析及上下文理解，文中提到"but you may try to reduce your use of electricity by turning off lights"但是你可以尽量的减少电能的消耗，比如随手关灯，由此可以推测前面提到的是不可能完全不用电，it's impossible to do sth做某事是不可能的，由此确定选择A．
53．D，考察介词短语辨析及上下文理解，文中提到"updating some of your electrical appliances to low-energy models"开始使用节能电器，后文提到"energy-saving lamps"节能灯，由此推测后文是在举例子，由此推测选择D．

点评 本题题型为选词填空．在选择给定词语时，再考虑文章大意的前提下，还应该注意文章及句子所用的时态，以及所填写的词在句子中的位置．通过这些判断，适当改变词汇形式，以符合题目要求．
