GWD30-21 困惑万分！怎么都找不到以前的讨论贴

Most of the purported health benefits of tea comes from antioxidants—compounds also found in beta carotene, vitamin E, and vitamin C that inhibit the formation of plaque along the body’s blood vessels.

 

 

 

1. comes from antioxidants—compounds also found in beta carotene, vitamin E, and vitamin C that 
2. comes from antioxidants—compounds that are also found in beta carotene, vitamin E, and vitamin C, and they

3. come from antioxidants—compounds also found in beta carotene, vitamin E, and vitamin C, and

4. come from antioxidants—compounds that are also found in beta carotene, vitamin E, and vitamin C and that

5. come from antioxidants—compounds also found in beta carotene, vitamin E, and vitamin C, and they

选择D,我的问题是，B和E中的问题是不是 they指代不明， 既可以指代Compounds 也可以指代antioxidants，这样分析不知道对不对？

是这样。they指代太不清楚，最有可能指代前一句子的主语benefits.

这句考的是定语从句的平行。

AB主谓不一致

BE定语从句不平行，compounds后面有两个定语从句，that are also found ... 和that inhibit ...,如果前一个定语从句省略了that are， 那么后面一个定语从句也应该是同样的形式，如：that are inhibiting ..., 这时，就可以省略that are，变成compounds also found ... and inhibiting ...

但在这个句子中，后面的定语从句的谓语为inhibit，所以要平行的话，前面的that are就不能省略。至于CE选项后面用了they，显然没有达到平行的目的。
