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.
这题A选项的比较对象我没搞明白，按照答案来看应该是this year 和last 做比较 我没有选A的原因是因为我以为是Heating-oil prices are expected to be higher this year这句话和last做比较，这样就是比较对象不对等，这样应该是than they were last year，才能对等，。。。 但是答案是选A，那应该怎么判断到底是什么和什么做比较，为什么A选项里面的last就可以对等了？ are paying about $5 a barrel for crude oil more than they did 还有后面这句各个选项不同的表达有什么区别
