##### 考题讲解

A选项：Correct. 本选项在语法和逻辑上均是正确的。比较对象是this year和last year，即，两个年份。

B选项：rise表达了“上升”的意思，而higher表示更高。在逻辑上，rise的结果一定是“使得某物higher”，因此，rise或higher只能存在一个，higher赘余；

C选项：比较对象不对等。比较两个年份的价格在本题中也是可以的，但是，last year's在than的身前无法找到平行对象，可以改为： this year's heating-oil prices are higher than last year's prices.

D选项：
higher…over…习惯用语错误同(B)。

E选项：
