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

(C) a substance that promotes blood clotting, but does not seriously interfere

(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

请问选项C和D有什么区别？我选的D，可答案是C，a substance that promotes blood clotting做补足语，修饰前面的可thromboxane；D中which is a substance to promote blood clotting，就近修饰prostacyclin又有什么错呢？也不妨碍suffices与interfere平行啊？不理解PREP的解释，请指教？

我的理解.C中是做A SUBATANCE 同位语,后面用定语从句修饰.

而D中,即使可以用,WHICH (但是很累赘),又有歧义,因为which is a substance to promote blood clotting, but (WHICH )does not seriously interfere赶边了原因.C避免了起义,是喜欢的同位于.

我觉得a substance尽管后面是限定性定从，整个这句话a substance that promotes blood clotting就是做 thromboxane的同位语的。没什么问题，C我理解。但是D我觉得也没什么问题，你说会产生歧意，我觉得不会，因为有but这个连词，你再把后面的production of prostacyclin与前面的production of thromboxane对照，很明显是平行结构啊！所以我还是不理解！我觉得是不是ETS喜欢同位语，或者分词结构修饰啊，相对于定语从句来说。

后来想了想,对which is a substance to promote....我觉得关键在这，promote 本来做实在定于从句中的，施动者在a substance 就是thromboxane，现在在d中表现为 目的状语，但是原文并没有此意。你觉得呢？

rolar

我刚看到，觉得C和D真的从意思上来说区别不大，无论是同位语，还是非限定从，还是你说的目的状语，我觉得区别真的不太大，我们是不是该从ETS的喜好来选择？看ETS喜欢什么样的句子特征，来判断？你说呢？语法上来说，我看不出啥区别了！

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

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

(C) a substance that promotes blood clotting, but does not seriously interfere

(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

请问选项C和D有什么区别？我选的D，可答案是C，a substance that promotes blood clotting做补足语，修饰前面的可thromboxane；D中which is a substance to promote blood clotting，就近修饰prostacyclin又有什么错呢？也不妨碍suffices与interfere平行啊？不理解PREP的解释，请指教？

PREP的解释是什么? n能否贴出来?

我觉得D因为but的存在,整个句子结构都错了, 这里的but 不同于C的but, c里面 因为从句的先行词是a substance , 所以 that promotes blood clotting, but does not seriously interfere 可以看作是整个都修饰a substance

而在D中, thromboxane,  which is a substance to promote blood clotting, but does not seriously interfere   如果如rolar所说, 是平行, 即 promote 和 interfere 两个意思 平行, 但请注意这等于说是将 a substance to promote blood clotting和 but does not seriously interfere   平行, 势必在语法上不允许. 这样一来, but只能作为主句结构, 也就是成了主句的第二个谓语, 即于suffice平行, 而这样又违背了逻辑意思

不知道罗嗦了一大堆, 大家同意否?

好不容易现在才能上网，好像dingxiang没理解我的意思，我一直都认为说suffices 与interfere是平行的，but是连词，形成对称平行结构。而不是promote与interfere平行啊！而我的问题是a substance that promotes blood clotting作为thromboxane的同位语与非限定从 which is a substance to promote blood clotting修饰thromboxane又有啥区别呢？而且which is a substance to promote blood clotting还与最后的which prevents clotting形成对称！

prep关于D的解释我又认真看了下，说D中but does not seriously interfere更像跟which is a substance to promote blood clotting并列，作为thromboxane的谓语动词，这样就改变了原意。

那我就有个疑问了，but does not seriously interfere的主语怎么会是前面主句a low dose of aspirin usually suffices to block production of thromboxane的宾语啊？有这样的句式结构的吗？
