Oil rose higher than $120 a barrel on Monday as increasing prices for fuels, such as petrol and diesel, combined with lingering concerns over supplies from Russia to propel crude to its highest level in two months.
as引导的原因状语从句中increasing prices 是主语,谓语不应该是propel吗?为何用to propel?
combined 是分句谓语动词。不定式是结果状语。你从主句的动词rose (过去时)就可以判断出分词谓语也应该是过去时。
