老师,E选项,评估新技术,能否也理解成方案的可行性呢?如果推迟分析,等到了新技术,但是新技术会损坏物品,导致也可能无法实现目标?麻烦老师解答一下,谢谢!
A 是方案的副作用
啊,不好意思,是名词的所有格不是名词
Per mile不一定,只能知道总的,因为坐飞机的通常miles会多,总的fare也就增加。但是average不得而知。
and前后动词的时态保持一致
by 后面只能加名词或者动名词结构
十本是“L中有评论”+“出现在其他中世纪手稿”中,八本是“L中无评论”。为什么E:Electra没有伴随评论一起出现在其他中世纪手稿 是对的?只说了八本在L无评论,没说不出现在其他中世纪手稿中,也没说出现在其他中世纪手稿中时没有评论啊
in the construction "not so much X as Y", "not" isn't negating "X"—it's negating the "so much" part. these are 2 completely different constructions, with 2 different meanings.
A为啥不对呢....

我找的很简单

note that you have "compared to motor vehicles...", which implies that we are making a direct comparison between pollutants and motor vehicles (rather than between pollutants and pollutants, as in the correct answer. that's nonparallel and thus wrong.
"that" stands for" the total amount of pollutant "
the real problem is that "is" has no parallel in the first part of the comparison - i.e., the first part doesn't say "is emitted" or "are emitted" - and so the comparison is wrong.
毕老师,这个题目,A为什么不对呢?
