标题: 求教XDF小蓝题一枚~ [打印本页] 作者: sasa花音 时间: 2013-3-18 20:44 标题: 求教XDF小蓝题一枚~ .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) less of certain pollutants than those burning gasoline or diesel fuel
答案是E
请问（1）less不是修饰可数名词么？ 为什么可接pollutants? (2) 可否看成正确答案E省略了does？ 如果是，那么应该是 less of certain pollutants than does those burning gasoline or diesel fuel还是 less of certain pollutants than those burning gasoline or diesel fuel does呢？

less是little的比较级 修饰不可数作者: flonacui 时间: 2013-3-18 23:08
如果有dose的话是后面那种 因为这个题是主语比较 主谓宾全的主语比较后面加上dose是为了防止歧义而表明是比较的主语而不是宾语 但是这种情况下不需要dose因为本身不会产生歧义 vehicles powered by natural gas emit less of certain pollutants than those burning gasoline or diesel fuel those指代的是vehicles 所以是天然气的vehicles跟gosoline or diesel fuel的vehicls相比较 不会造成宾语比较的歧义 因为vehicles powered by natural gas不会emit those(vehicles) 所以就不需要加上dose了
