标题: 紧急求助：07PREP破解语法35题，各位帮帮我~
紧急求助：语法题一道，各位都帮我看一看吧~~
这是07prep破解上的一道题，本人语法有点烂，所以看了解释还是不太明白，还望各位亲爱的同学们帮帮我理解下~
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
(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
不理解之处：
这个是07prep笔记上关于选项C的解释
(C)正确, a substance that…独立主格结构作为thromboxane的同位语对thromboxane进行解释
说明; but does跳过同位语和suffices并列共同作为a low dose of aspirin的谓语动词。
为什么这个but does可以越过同位语与前面的动词并列？而选项B中后面的interfere就是和前面的promote并列的？有没有does有什么区别么？
先在这里谢过各位抽时间看帖子的同学们~Thank you so much!

同位语是修饰thromboxane的，可以当做定语来看，确定排除了A,D,E后，来读整句句子。你会发现这句话是这样的：
In laboratory rats, a low dose of aspirin usually suffices to block production of thromboxane, but does not seriously interfere with the production of prostacyclin, which prevents clotting.
这是整句话的主干，那个同位语你可以暂时不要管他。理清了思路以后，就可以选出正确答案了~

刚刚和一个NN讨论过，之前的我太钻牛角尖了，动词的否定前面肯定是要加助动词的，我一直纠结于为什么要加does，
evelyn这么解释我就更加清晰了！\(^o^)/~

还是这题，我还是不明白，还请NN继续指教。破解笔记上解释C说“but does跳过同位语和suffices并列共同作为a low dose of aspirin的谓语动词”但是对于D，却说“but does…更像是跟is a substance…并列,从而作为了thromboxane的谓语动词,改变了原句的意思”为什么呢？C 选项在but does前面也有个一般现在时态的动词“that promotes blood clotting”，我倒觉得更像是跟这个平行了，而不是跟前面的suffices平行，反而D 的更像是跟前面的suffices平行。并且，注意到D选项用的“which is a”，我觉得跟原句最后部分的“which prevents clotting"平行更合愿意。这样，D的主干其实就是“ a low dose of aspirin usually suffices to...thromboxane, which is a..., but does not...prostacyclin, which prevents...”

为什么可以排除D，求指教～D中but does not为什么不能跳过前面的which呢～
