It is common knowledge that healthy foods such as fruits and vegetables contain certain nutrients that promote good health—namely vitamins and minerals that are essential to the body. However, once these compounds enter the body and become digested, do they still possess the same healthful【C1】________? Do they still perform the desired action to create a【C2】________result?
That is what researchers at Newcastle University recently set out to【C3】________. 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】________. "There are certain chemicals we know to be【C9】________and we can identify foods which are rich in them but what happens during the digestion process is【C10】________to whether these foods are actually doing us any good," said Dr. Okello.
The research showed that【C11】________the polyphenols were digested in the gut, the resulting compounds had a greater ability to bind to toxic substances.
"Green tea has been used in Traditional Chinese Medicine for centuries and what we have here provides the scientific【C12】________why it may be effective【C13】________some of the key diseases we face today."
Tea is one of the many common and natural dietary【C14】________in Asian cultures shown by modern science to have【C15】________unique health benefits. Mushrooms are another common food that has been【C16】________for centuries. They are used【C17】________in many cooking, (notably Chinese, Korean, European, Japanese and Indian). They are also used in Traditional Chinese Medicine for their ability to promote immune health. Certain species of mushrooms-have great【C18】________abilities to regulate the immune system and promote【C19】________within the body. These mushroom species【C20】________benefits even after digestion and absorption into the blood stream.
【C2】
选项
A、definite
B、valid
C、positive
D、distinct
答案
C
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”。A项definite“确定无疑的”,但正是因为结果不确定,才会提出这两个问题。B项valid“有效的”指具有法律效力或约束力,不能修饰result。D项distinct“明显的,截然不同的”,强调的是可辨别的、不同的结果,无法准确体现上下文语义中所暗含的褒义。
