Scientists analyzed the polyphenols, a type of antioxidant, in green tea to see how they【C4】______the body once digested.【C5】______the polyphenols in tea are known for health benefits, Dr. Ed Okello and his team wanted to better understand how these polyphenols act once【C6】______the body. Their study, which was recently published in the journal, showed that the chemicals【C7】______the breakdown of polyphenols were more effective at promoting health than the polyphenols【C8】______. \\
1.【C1】(A)
A. qualities
B. traits
C. standards
D. conditions
解析：上句提到水果、蔬菜等健康食物含有促进身体健康的营养物质。本句顺接上文，讨论的是这些化合物进入人体并被消化后(become digested)是否还能发挥同样的作用。A项qualities“品质；性能”，代入后表示保有同样的健康属性。
2.【C2】(C)
A. definite
B. valid
C. positive
D. distinct
解析：本句与上句是并列句，需填入形容词作result的定语，与healthful及promote good health构成语义呼应，表示褒义，故选C项positive“积极的”。
3.【C3】(B)
A. locate
B. discover
C. invent
D. identify
解析：上段提出了两个伺题，本段顺接上文，讨论最近纽卡斯尔大学的研究员开始着手做的事情，由此可推断他们是通过研究来解答这两个问题。B项discover“找出”可以与上述两个问题构成合理的语义关系。
4.【C4】(D)
A. change
B. reflect
C. promote
D. affect
解析：空格处填入动词作宾语从句的谓语，表明主语they(指代polyphenols)及宾语the body的关系。D项affect表示“影响”，与act(起作用)语义呼应，填入文中指茶多酚被消化后会对人体产生什么影响，语义通顺。
5.【C5】(A)
A. Although
B. Unless
C. Since
D. Even
解析：上半句提到我们已经知道的是绿茶中的多酚(polyphenols)有益健康，下半句指出EdOkello博士和他的团队仍想进一步了解它们。前后之间存在着语意有一定的转折关系，空格位于句首，选A项Although“尽管”。
6.【C6】(D)
A. upon
B. across
C. along
D. inside
解析：上文提到茶多酚会被消化(once digested)，所以它起作用的这一过程应发生在体内，故选D项inside“在……里面”。
7.【C7】(C)
A. resulting in
B. suffering from
C. resulting from
D. drawing from
解析：上文谈到茶多酚到达体内会被消化分解，因此这里说的the chemicals应该是茶多酚分解产生的化学物质。C项resulting from“由……而产生”正确。
8.【C8】(C)
A. enough
B. only
C. alone
D. lonely
解析：本句讨论在多酚在分解前后(即the polyphenols和the chemicals)在促进健康方面的比较，the chemicals效果更明显(more effective)，因此空格处词语应具有强调意义，选C项alone。only与alone作形容词均可表“仅有的，单独的”，但alone须置于被修饰词之后，only往往置于被修饰词前，因此排除B项only。
9.【C9】(B)
A. harmful
B. beneficial
C. sound
D. profitable
解析：此处讨论的都是化学物质的益处，后半句也表明要判断这些食物是否确实对我们有益(whether these foods are actually doing us any good)，推测空格所需形容词应与doing us any good语义呼应，故选择B项beneficial“有益的”。
10.【C10】(A)
A. crucial
B. necessary
