more修饰“5 a barrel”说明今年比去年每barrel多付5刀,如果把more放在oil后面,就变成了oil的价格是5刀每barrel,含义是不一样的。所以排除BCE。
D开头的结构太复杂了, 不好。关于“higher this year than last” ,之所以可以省略they were,是不是因为year本身是无法用higher做比较的,所以省略也不会造成歧义?
看到这么一个解释refiners pay about $5 a barrel for crude oil more than they did.
当more做形容词时:
crude oil (more than)they did:他们去年支付的油钱比5美元还要少
当more 做副词时:
crude oil (more)than they did:比去年支付的油钱多付了5美元(intended meaning)
还是不明白比价格变成比时间,谁能讲讲呢?
我认为,more的位置与paying有关,因为在这句话里,more是修饰paying。因此***paying $5 a barrel more*** 中,a barrel是个修饰语吧我觉得,就是类似income per hour一样,如果带着它别扭,那就把它删掉,这样,这句话就比较清晰了:paying $5 more for crude oil,对于石油,他们每桶多付了五刀。
这里应该还是价格的比较,只是做了省略
根据曼哈顿SC书里写的:You can omit units,verbs and then whole clauses from the second term, as long as there is no ambiguity in the comparison.
e.g. I walk faster than Brian (walks).
I walk as fast now as (I walked) when I was younger.
括号里的为省略部分
总结一下前面楼层的。小伙伴说的这些可以省略,楼主也提到只有时态不同还有有歧义是不能省略。加上RON说这个题there's no problem with tense shifting here, since infinitives don't have a tense (i.e., "to be" is neither anchored in the present nor anchored in the past)。这道题比较两年的价格的情况下,last(year)前面省略了(they (指价格)were)。
