简单题！错
考察：
未画线部分并列（不要省略不看啊），单复数主语一致（单复数好爱考察）；
前：besides可以加doing ， in addition to只能加do；

中：its；找到后面的主语是“the brewed leaves”，那么前面besides后面的its显然单复数错误。排除abc；

后：d的语意错误the preventing and inhibiting of the cancer意思是cancer的阻止和抑制，应该是作为动名词preventing and inhibiting the cancer

其实看到besides这一类就该马上想到要出现并列了；后半部分play a role in . 这是一个角度
另一个角度，“除了可能性，the brewed leaves还扮演了一个角色”❌； 除了doing sth，做伴随状语，the brewed leaves 还做了 sth，✅

教训，一定要读完后面未画线部分去体会句意，而不是光看选线possibility就去选了。未画线部分才是关键有时候。

(d) "the possible VERBing" is inferior to "possibly VERBing".
"and" doesn't make sense in context (it makes it seem as though the two effects must occur together); "or" makes more sense.

in general, ACTION NOUNS (adoption, destruction, etc.) don't imply that the subject of the sentence is performing the action; they usually refer to the general notion of that action.
by contrast, -ING forms do usually imply that the subject of the sentence is the actor.

here are two simpler sentences to illustrate:
i want to learn about adopting dogs --> implies that i actually want to adopt dogs myself.
i want to learn about the adoption of dogs --> i want to learn about dog adoption in general, but there is no implication that i actually want to adopt any canines into my own home.

1. ABC的in addition to and besides 都是介词用法，后面接名词或者名词成分，例如动名词和从句。最大的错误是两个用语后面的名词成分都必须在句子中与一个成份形成实际意义上的语义逻辑上的平行关系。而ABC里的possibility在后面句子中找不到对应的词。
2. ABC的It指代问题，应该是leaves，复数
3. D and E, D的possible ＋动名词 preventing and inhibiting没有E的possibly preventing or inhibiting好，原因有二，一是 D中and不如E中or在语义逻辑上更准确。Ron说这两个词是mutually exclusive，不可能用and同时发生，肯定是or。同理还有一个句子里有damage and destroy，也是应该用OR，而不能用and；二是 D中possible修饰preventing 以及inhibiting，应该用副词形式修饰这两个动作。若用形容词的possible，就用prevention更合适。

关于it指代： The structure of the sentence is "In addition to X, Y". This structure implies that X and Y are two observations of the same kind. Here, "Y" says that the brewed leaves do xxxxx. So, for "in addition to" to make sense, "X" should be another statement about the brewed leaves. Not about something else (= the tea itself).

(d) "the possible VERBing" is inferior to "possibly VERBing".
"and" doesn't make sense in context (it makes it seem as though the two effects must occur together); "or" makes more sense.

A. its possibilities与后面的句子“the brewed leaves of Camellia sinensis may also play a role in reducing the risk of heart disease and stroke.”没有对应的成分。并且没有possibility for doing的用法
B. its possibilities与后面的句子没有对应的成分
C. the possibility与后买呢的句子没有成分对应。由于;分割两个完整的句子，所以it只能够指代后面的成分，这里应该是leaves，是复数谓语动词应该用复数
D. prevent inhibit是阻止阻碍的意思，两者是mutually exclusive，不能够用and。并且如果用possible，prevention和inhibition更好
E. right，prevent inhibit两者是mutually exclusive，只能够用or。

c我以为it指代的是单数tee。。
标点；分开两个完整的句子，所以一切代词都只能指代后半句的主语leaves，排除abc

possibility of doing

besides，介词或副词，C/D是介宾结构，E是伴随状语，逻辑主语是leaves，除了阻止癌症，叶子还可以扮演降低风险的角色，ok；除了可能性，叶子还可以扮演降低风险的角色，不好。

in addition to/besides/as well as是介词，虽然不是并列词，但语意上要求句子里有成分可以与其并列。
A/B/C的possibilities只能与主句的名词并列，表达的意思是：除了（减少）可能性以外，还能减少风险。
E，besides preventing与主句的动词并列，表示除了预防癌症，还可以减少风险。

B，possibilities控制力弱，不接to do

and/or：预防癌症是在癌症发生前预防；阻止癌症是在癌症发生后阻止它扩散，二者不能同时发生，不能用and

choice ABC:作为状语的 介词宾语结构中的核心词都是possibility。导致语意出现了变化：除了可能性，叶子还能减少心脏病和中风的危险
choice D,也是介词宾语结构作状语， possible 做形容词修饰动名词 preventing,inhibiting 。但问题出在of some forms of cancer，语意是某些形式的癌症所拥有的预防和抑制

D.besides做介词+名词，可以做定语也可以做状语，如The cat on the couch loves dogs. on the couch做定语。
E.besides是副词+动词，-ing可以做定语也可以做状语，如The cat sleeping on the rug belongs to Sue.
从词性上无法区分。看and和or的区别。

主要是动名词preventing & inhibiting要用adv修饰 而不是Adj修饰

第一，it不能只带复数的leaves；第二，possibility of/that应该更恰当；preventing和prohibiting可与in reducing作平行结构，且最好不要用and 连接？

根据语义，prevent和inhibit与reduce the risk 平行，所以abcd都可以排除
还有it语义上应该指代leaves，单数it不能指代复数，所以abc也可以排除

besides adv. prep.

一定要用心体会 prevent OR inhibit 这里最好不要用and

the possibility ~ (of sth/doing sth); ~ (that...)
①The possibility of breaking the world record never occurred to him.
②Is there any possibility that we'll see you this weekend?
③What is the possibility of the weather improving?
