Heating oil prices are expected to be higher this year than last.请问这个句子省略之前是怎么样的?
是Heating oil prices are expected to be higher this year than(heating oil prices are expected to be) last year.
还是Heating oil prices are expected to be higher this year than(heating oil prices are ) last year。
但是last year得话,than之后就应该是were了吧,那这样不就不能省略了,为什么原题省略了?
