Heating-oil prices are expected to be higher this year
than last because refi ners 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 refi ners 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 refi ners 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 refi ners
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 refi ners
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 refi ners
pay about $5 a barrel for crude oil more than
they did

这题选A，想知道A选项中的last 后面为什么可以省略"prices in last year"??  很多比较结构不是一定强调对比的内容一定要可比吗?到底什么时候可以省,什么时候需要写"than that of XXX 或者than XXX's; 说实话,当初我感觉每个答案都错,因为后面几个选项中rise和 higher意思重复,但这点OG上没提...

The roads are much quieter in Xiamen than (the roads are) in Shanghai.
如果比较的对象两者 主语 和 谓语 都相同，那么主语 和 谓语 就可以省略。只保留状语，lz可以翻一下语法书。
此题同理。
有 than that of XXX 的 一定是 比较 宾语。
自己总结的比较题目的做题方法

1、首先判断句子是 SVO 结构 还是 SV 结构  --- 即有无宾语

2、如果是 SV 结构，（也就是没有宾语的情况）如比较主语，则，无需补出助动词 do, did ....

3、如果是 SVO 结构，根据题目意思 判断是否是 比较 主语

如果是，than 后面必须补出谓语动词，或者助动词（看选项，未补出did, do 等新动词 或 助动词的都错）

如果不是，不存在补出问题，
1、看比较成分（状语）形式是否一致即可
2、若为宾语比较需要补出 that / those

感谢回答，但是即便不需要补出，为什么last 可以替代 last year? 完全可以是last two years,etc. 难道英语里面经常有这样的用法吗？ 我只见过形容词+the可以表示一类人或事物，从没见过如此这般省略的形式,求高人指点。

这个地方的省略应该是they were（主谓语一致）；但个人觉得由于时态变了，这种省略是不是可行的需要商榷。最理想的答案补出helping verb：they were 比较好。
MANHATTAN里应该清楚说明在不同的tense时态中，是要用the working verb的

千行OG里有：

TWO INSTANCES IN WHICH YOU CAN'T JUST USE A NOUN:

1) VERB TENSE SHIFT

if there is a change in verb tense between the two halves of the comparison, then you MUST include the verb in both halves. (if the verb is omitted in the second part of the comparison, then the implication is that the tense is the same in both halves.)

so:
Heating-oil prices are expected to be higher this year than they were last year
--> correct
BUT
if you wrote
Heating-oil prices are expected to be higher this year than last year
then this would be incorrect, since there must be a tense shift between what is happening this year and what happened last year.

2) AMBIGUITY

i know more about shakespeare than my brother
ambiguous. 2 meanings.

又有联想（见千行OG）：

个人见解：

并列句也就是所谓的two independent clause，而比较句是一个independent clause里面内置的比较结构

一个是两个句子，一个是一个句子；所以，可能是为了清晰或者unambiguous，第一个的helping verb的补出在

时态不一致的情况下，是要补出 exact working verb


open to discussion


所以呢…B选项的helping verb补出应该是没有错误的，但是C选项肯定是错的（B中的是working verb，C中的是are引导的progressiveness）

这题的选项中有其他太过于明显的错误，上述的知识点只是和其他人讨论所得出的理论，可以说是extremely subtle difference或者根本就不存在这种rule

建议大家不要太多纠结。



最后，再次回归SC的考点主旨：并不是正确的句子就是最理想的表达方式，SC的题目是让你选择所有答案中最佳的答案。根据这点中心原则，肯定A无误！
