标题: V ADANCE里的一句话 ,急 [打印本页] 作者: awishtosuccess 时间: 2009-12-28 12:44 标题: V ADANCE里的一句话 ,急 4. Because natural gas is composed mostly of methane, a simple hydrocarbon, vehicles powered by natural gas emit less of certain pollutants than those burning gasoline or diesel fuel. (C-p8-16)
我觉得怎么少了一个DO
应该是than do those buring g or d fuel?
NN求教.这是主语比较啊!
还有一句
3. In addition to having more protein than wheat does, rice has protein of higher quality than thatin wheat, with more of the amino acids essential to the human diet. (B-p106-19)
为什么冒出来一个in?可以解释下结构吗?(此句是归在宾语比较里面的)作者: nancyyen 时间: 2009-12-28 15:34
1）主语比较没有说一定要加do只要没有歧义。（我自己的看法是答案中有避免歧义的选项没有明显语法问题就选，如果答案都没有就不管了。。） 2）这个红色部分有2个处理办法，第一，比较宾语部分，也就是文章的处理方法，那than后面也要是protein，所以，that代替protein，但是that和wheat之间也需要有个连接的东西吧，我觉得in/of都行。第二个办法，如果你要比较主语 rice和wheat（我估计是楼主的想法），就是than+wheat does （have也行我自己觉得）作者: awishtosuccess 时间: 2009-12-28 16:44
