Prep07 35题再问...

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

In laboratory rats, a low dose of aspirinusually suffices to block production of thromboxane,

which is a substance that promotes bloodclotting, but not seriously interfering with the

production of prostacyclin, whichprevents clotting.

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

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

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

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

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

Prep07语法笔记说:

(C)  正确, a substance that…同位语结构，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

(D) 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

可以理解D说更像和is a substance并列，但是，为什么C中but does就跳过同位语和suffices并列了呢？在我看来，非常像和 that promotes并列了啊。

还有一个问题，but作并列的时候，是不是和and类似？这里如果but后能够有指代主句主语的代词it，我觉得才像是和主句并列啊...

求指教！谢谢

解释有问题吧，觉得interfere是和promote并列的

ffen

额，可是意思上看上去好像还是和前面平行的，因为前面说 production of thromboxane，后面又有production of prostacyclin，所以应该还是和suffice平行吧。

ffen

自己顶一个...还是没明白啊...

D的问题是to promote bloodclotting，名词后面或者加that从句，或者加现在分词，没见过加to do的

啊？这个说法没见到过嘛...脑海中蹦出了一句句子, I have a chance to be a doctor.这个不是n+不定式么...
不过，确实有看到同学说D中改成不定式有点改变了句子意思。
我主要还是想知道C中的并列到底怎么一回事...><
Anyway,谢谢哈！

这个句子结构不一样，i mean 修饰名词的成分

我觉得语法笔记上的解释让我很疑惑，关于这道题我有这样几个想法
1、OG上很多正确的句子都是n. ,a n.——同位语用来解释逗号前名词
2、C选项中 a substance that promotes blood clotting和后面prostacyclin, which prevents clotting一个是promotes blood clotting一个是 prevents clotting结构很平行
3、to do做名词的后置定语表目的为什么不可以？
4、D中得绝对性语法错误没有的话，我觉得是因为用which不够简洁

刚刚想问这道题，但是搜到了以前别人问的，就同主题了吧。主要原因是我和原帖LZ的疑问一模一样，但是上面的回复貌似都没有真正解惑呀！
这么长时间过去了，有没有NN有更清楚的解释呀？感激不尽！

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

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

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

(C) a substance that promotes blood clotting, but does not seriouslyinterfere  正确答案

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

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

解释说D的but does。。。更像是和 is a substance。。。并列。但是C也可以误解为promotes 和 does not seriously interfere平行修饰前面的a substance呀？

跪求解答。
