D 第一点 are在前面找不到平行的结构 如果要用are的话 前面应该是 prices of xxx are xxxx than they are.....
第二点 我是从指代上发现的 因为虽然都是prices 但其实不是同一个prices 应该用those 来描述一个new copy 不知道对不对呢

Industry analysts said that the recent rise in fuel prices may be an early signal of the possibility of gasoline and heating oil prices staying higher than usually through the end of the year.

A. of the possibility of gasoline and heating oil prices staying higher than usually through---- 1. redundancy of may and possibility as already pointed out. 2. usually has no verb to modify, a dangling adverb


B. of the possibility that gasoline and heating oil prices could stay higher than usual throughout--- 1. redundancy 2. throughout and through are meaning - wise different.

C. of prices of gasoline and heating oil possibly staying higher than usually through ----- 1. redundancy 2. dangling adverb

D. that prices of gasoline and heating oil could stay higher than they usually are throughout----- throughout and through are meaning - wise different.

E. that prices of gasoline and heating oil will stay higher than usual through -- correct choice

General: All reported speeches are presented in a relative clause introduced by 'that'. Hence D and E are stylistically better than A. B and C.

Through the end of the year means from now until the end of the year, period by period or event by event. As we are in June now, through the end means the rest of June, the entire of July, August, September, and so on until the last day of December. On the contrary, throughout the end of the year doesn't convey any sensible meaning except to refer to the last of the year. The end of the year marks a particular short point of time. There is no meaning in saying throughout that the short period.
Through means from one point to another. Throughout means entirely

usual price 省略了price 这个名词

possibility和may是重复的，只要一个就好了。

signal 一个信号 信号是一个事件，不是可能 也不是价格
D than 后面出现are 前面没有对应的be动词 错误

A选项：of the possibility of 是wordy的表达；higher than usual而非usually;
B选项：of the possibility that 是wordy的表达; throughout the end of the year有问题；
C选项：possibly冗杂，higher than usual
D选项：could stay与may所表达的可能性重复；thought the end of the year不合适的习语；
E选项：will stay表示预测的可能性；higher than usual; through the end of the year都是规范的表达；

b为啥不对？

想问下e里的usual是怎么省略的，还原之后是than the usual prices吗

s+v+o+c()
主语？时态？比较！

than usual/ ever before/ previously expected/previously estimated/ anticipated…

再次爆炸；DE纠结，主要是被E中的will 这种词给影响到，因为我认为这表示一个可能性，从A中的Possibility中可知作者是想表达这种可能性，那么用will就觉得很怪

D的than they usually are明显跟前面不平行啊

D哪里错了？
