OG 12 -93

Heating-oil prices are expected to be higher this year than last because refiners are paying about $5 a barrel more for crude oil than they were last  year.

(A) Heating-oil prices are expected to be higher this year than last because refiners are paying about $5 a barrel more for crude oil than they were

(B) Heating-oil prices are expected to rise higher this year over last because refiners pay about $5 a barrel for crude oil more than they did

(C) Expectations are for heating-oil prices to be higher this year than last year's because refiners are paying about $5 a barrel for crude oil more than they did

(D) It is the expectation that heating-oil prices will be higher for this year over last because refiners are paying about $5 a barrel more for crude oil now than what they were

(E) It is expected that heating-oil prices will rise higher this year than last year's because refiners pay about $5 a barrel for crude oil more than they did

这应该是今年的价格和去年的价格的比较，所以不是应该是last year's吗？为什么A是对的？答案上解释E时说last year's 没有和this year平行，这点也很不理解。希望有人能帮着解答下

rise higher,冗余。排除B E.

C 语法错误。expectation不能higher

D 强调句式，但than what they were是冗余。另外are paying和Now搭配也啰嗦了，现在进行时描述的本来就是现在的情况。

A。 they were, were正好对应are paying的助动词are。如果前面写refiners pay....那么后面应该出现than they did。这里都是动作pay的比较。

谢谢你啦~但是还是有些个小疑问~2楼提到expectation 不能用high修饰，我查了下字典，expectation 是可以用high来修饰的，下面这个事例句。

Women who have
                high expectations
            of marriage are often disappointed.

还有一个就是可否解释下第一个than的比较对象，就是原文中的

Heating-oil prices are expected to be higher this year than last

再次谢谢啦

我的意思是expection高了没有用，价格才是那个选项的核心。没说清楚，我懒得改了。1st than比较的是prices

A、是refiners are ...more ...than they(指代refiners) are 平行

C、 this year than last year's ，一个是时间，一个是 last year's ，不可比
