疑问：文章挺简单，但有几个空和网上答案不太一致。先说最后两个空14和15，我选的14是economical，15是efficient。但网上答案它两个正好倒过来。
另外第一个空可以是improvement吗，网上答案是make a big difference.
第5个空填什么，可以填burning吗？
全文的主题是节能。If you own a 4 x 4 vehicle, why not consider trading it in for a more efficient vehicle. The only reason you should need a 4 x4 vehicle is if you live in a rough terrain or snowy areas. When you need to buy your next car, be sure to check the miles per gallon to see how economical your car will be, this not only helps the environment but is saves you money on fuel too.efficient:能产生成效的。economical：不浪费燃料的。再看一下上述这几句话的中文意思:假如你有一辆4*4型号的汽车，为何不考虑换成一辆更具节能成效的车呢。假如你住的地方路不好走或者长期积雪那开4*4型号的车未尝不可。当你需要再买车的时候，必须要弄了解每加仑的英里数，看你要买的车费不费燃料，如此不只能够帮助环保而且还能节省油钱。burn你查词典会发现它有一个意思是：消耗，譬如:burn much gasoline消耗不少汽油。burn electricity在这里是耗电的意思，文章中用的是目前进行时态，burn需变为burning的形式，即：is burning electricity。即便手机不充电，假如充电器插头不从电源拔下来的话，它依旧会耗费电。最后一个问题make a big difference in doing sth是一个固定使用方法，你搜一下百度极少能发现有make a big improvement in doing sth 的使用方法，这是完形填空最准确常见的还是difference。期望能帮你。
