C中的it作为定从的主语只能指代possibility，这是定从结构所决定的必然结果。

偶认为C里面的是同位语从句，besides the possibility that + 从句 是固定用法吧。

我选C

我想到了og48，大家注意关于AD错误的解释：

The golden crab of the Gulf of Mexico has not been fished commercially in great numbers, primarily on account of living at great depths—2,500 to 3,000 feet down.

(A) on account of living

(B) on account of their living

(C) because it lives

(D) because of living（C）

(E) because they live

Choice D, like A, fails to provide a noun or pronoun to perform the action of living, but even with its the phrases would be more awkward and less clear than it lives

AD的错误和本题的E很像，没有指明是谁预防抑制病症，实际上og48可以合情理的看出是living的主语是crab，但是ets还是认为错了。而这道题有两种可能：起一直预防作用的，一个是茶本身，一个是泡过的茶叶。

综合看还是C比较好。明确作用是茶本身的。

还有and 和or的问题，开始觉得一定用and好，后来觉得or好。请大家讨论。

这个题和问得题不同，33题得逻辑主语在后面，所以不要it.

Q33:

The health benefits of tea have been the subject of much research; in addition to its possibilities for preventing and inhibiting some forms of cancer, the brewed leaves of Camellia sinensis may also play a role in reducing the risk of heart disease and stroke.

1. in addition to its possibilities for preventing and inhibiting
   
2. in addition to its possibilities to prevent or inhibit
   
3. besides the possibility that it prevents and inhibits
   
4. besides the possible preventing and inhibiting of
   
5. besides possibly preventing or inhibiting

Remember, there is an "also" here.

The leaves ....may also play a role

This means that another function of the leaves is that they can prevent....

我对c的理解是，besides后面要是能够平行还是尽量平行，从这点上来说c并不好。而且c中possibility后面的it有问题，应当去掉

bose0008

the subject of the sentence is: "the leaves",

the leaves can: prevent/inhibit, also play a role...

A, B, C are all wrong in terms of referent "it" "its"

in C, the possibility that... (the subject of the clause is still "the leaves")

E is the right and paralleled choice

Besides possibly preventing or inhibiting some forms of cancer, the brewed leaves of Camellia sinensis may also play a role in reducing the risk of heart disease and stroke.

Means,

The leaves play a role in doing...., and/besides (in )  doing

besides的作用表示包括这项功能，是个并列的意思

我一开始也觉得是C，但是现在觉得是E。理由：

beside doing sth 与play an role in doing sth 对称

但是it也有可能會指涉到research, 所以有it的選項都不用選
