以下是引用笨笨可可在2008-7-2 3:57:00的发言:1. Because natural gas is composed mostly of methane, a simple hydrocarbon, vehicles powered by natural gas emit less of certain pollutants than the burning of gasoline or diesel fuel. (A) less of certain pollutants than the burning of gasoline or diesel fuel (B) fewer of certain pollutants than burning gasoline or diesel fuel do (C) less of certain pollutants than gasoline or diesel fuel (D) fewer of certain pollutants than does burning gasoline or diesel fuel(E) (E) less of certain pollutants than those burning gasoline or diesel fuel 首先我对于D和E的看法是这样的。。D fewer修饰的是可数名词pullutants,than后面补足了助动词does,但是缺陷就是than后面不对称了。 E的看法是less of我认为修饰不可数名词,than后面对称,但是我认为最好补充出do。。 所以这都有问题,那不存在正确答案。。 open to dicusss. 我觉得dingxiangMM的意思是:如果选项里有fewer certain pollutants than ...那么就是正确选项了。而D选项多了一个of。E的用法是less of +的用法 |
