According to a recent study of consumer spending on prescription medications, increases in the sales of the 50 drugs that were advertised most heavily accounts for almost half of the $20.8 billion increase in drug spending last year, the remainder of which came from sales of the 9,850 prescription medicines that companies did not advertise or advertised very little.

A. heavily accounts for almost half of the $20.8 billion increase in drug spending last year, the remainder of which came

B. heavily were what accounted for almost half of the $20.8 billion increase in drug spending last year; the remainder of the increase coming

C. heavily accounted for almost half of the $20.8 billion increase in drug spending last year, the remainder of the increase coming

D. heavily, accounting for almost half of the $20.8 billion increase in drug spending last year, while the remainder of the increase came

E. heavily, which accounted for almost half of the $20.8 billion increase in drug spending last year, with the remainder of it coming

heavily accounted for almost half of the $20.8 billion increase in drug spending last year, the remainder of the increase coming

主要问题是这里为什么是coming, 独立主格后面加过去分词或现在分词都可以,为什么不是用came呢

with复合结构中，宾语和宾补之间形成逻辑上的主谓关系。当这种主谓关系表现为主动语态时，用现在分词；当这种主谓关系表现为被动语态时，用过去分词；当这种主谓关系表示将来意义时，用不定式；当这种主谓关系表示伴随意义时，用现在分词或副词。

答案是C, C中为什么是用coming 啊...一直没理解

如果用D，这个句子找不到谓语，如题上所标注。用这个点排除A(increases复数， accounts 错), C, D。而B中其他的不说，第二句因为用分号隔开，应该是独立的句子，但不是，所以排出
