41.比现在知道更多的知识，所有应该是they do now，如果只是now，则是时间的比较。
93.higher this year than last，这个是时间的比较。
关键还是要看清到底在比较什么。不知道有没有回答你的问题，可以再多看看讨论帖自己揣摩一下。

楼主你现在明白了么？我也在纠结41 和93 不明白不明白啊

mdautobox · 发表于 2011-4-21 22:54:10

怎么没人回答啊~~
我也不太懂啊~~ 答案说的是 this year 应该和last year 比~~但是总觉得price才是比较的中心啊~

怎么没有人觉得A里are paying很奇怪吗？为什么要用进行时呀

关于A选项的比较问题：
When comparing time or place, you have two options for structuring the comparison:

1. Joe studies more at night that he does during the day. (The sentence compares Joe to himself.)

2. Joe studies more at night than during the day. (The sentence compares "at night" to "during the day.")

但是对于选项末的were不太理解，不可以是refiners are paying和they paid 来比较么？？

正好在复习这题

个人认为这道题, 比较前部分无论是用refiners are paying, 或 refiners pay, 后半部分无论是用than they were (paying) 或 than they paid, 都是可以成立的. 只不过前面要是说refiners pay, 后面就不能说than they were 而是要把时态补全than they were paying.

考点在于看出其它的语法错误(如rise higher, expectation...etc.), 还有不错误排除正确的语法点.
