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

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

答案是A，我选了E，答案说this year和 last year's 不平行，但是这道题不是今年与去年的价格相比较吗，那E就是prices this year和 last year's比较，应该是对的呀。而A是两个年份相比较，意思上不对阿 请求指教阿

last year's是所有格结构，去年的什么什么，和this year当然不平行拉
