标题: 请教PREP 1-35

35. (26325-!-item-!-188;#058&002592)

In laboratory rats, a low dose of aspirin usually suffices to block production of thromboxane, which is a substance that promotes blood clotting, but not seriously interfering with the production of prostacyclin, which prevents clotting.

(A) which is a substance that promotes blood clotting, but not seriously interfering

(B) a substance that promotes blood clotting, but not seriously interfering

(D) which is a substance to promote blood clotting, but does not seriously interfere

(E) which is a substance that promotes blood clotting, but not a serious interference

answer is C

我的疑问是为什么不可以是B，这里是什么语法点啊？谢谢

suffices.....interfere并列，要ｐａｒａｌｌｅｌ

ｓｕｆｆｉｃｅｓ和ｄｏｅｓ　ｎｏｔ　ｉｎｔｅｆｅｒｅ并列

我也想知道D为什么不对啊？

D 的意思是修饰 thromboxane 而非aspirin

我觉得C也有问题呀，does not interfere存在歧义，与promotes并列。。。。。。

是which is 整体省略了让句子更concise了，that从句里promotes和does not ...并列，用动词，不能一个用动词，一个用分词阿，因为中间有个but

的

以下是引用A00A在2007-8-15 17:28:00的发言：

D 的意思是修饰 thromboxane 而非aspirin

我觉得并不是这样 which定语从句就是该修饰t物质没错 D错在which的运用上不如同位语简洁（Gmat一向对同位语有特殊的偏好）更重要的是to promote表达出了不应该有的“目的性”的意思
