prep 2-138 请教，就要考了，急!

A middleweight black hole weighs in at roughly 500 solar masses, hundreds of times more massive than the lightweight black holes produced by the collapse of individual stars, but thousands or even millions of times less in its mass as the heavyweight giants that lurk in the centers of galaxies.

(A) thousands or even millions of times less in its mass as

(B) it is thousands or even millions of times less massive as

(C) thousands or even millions of times less massive than

(D) yet it is thousands or even millions times less massive than

(E) yet it is thousands or even millions of times less in its mass than

the answer is C,but i can not understand.  please help me! thanks!

考点1：less...than.

考点2：结构对称。前面是more..than,后面对应也是比较结构，而且句子本身就是在比较。

less后面肯定有than，是比较，其他的一概都错，as当然不对，所以1.2选项排除。

选项4.5错。原句中已经有but作转折了，这属于多余的词汇，不符合SC的简洁风格，而且本身也就是错的，repeat了。

所以选3
