Now it turns out that tea, 2 chicken soup or echinacea, is what can give your body an extra 3 to help it battle infections.

Given 20 ounces of tea daily, non-tea drinkers were better able to fight 4 bacterial diseases, according to a study at Brigham and Women's Hospital in Boston. The researchers 5 L-theanine, an 6 found in black, green, oolong and pekoe teas--but not in 7 teas, which usually don't contain Camellia sinensis, the one true tea 8 .

When broken down by the liver, L-theanine becomes an antigen called ethylamine, 9 primes the response of gamma-delta T cells against a 10 of bacterial, viral, fungal and parasitic 11 , and possibly tumors. (Ethylamine is also found in other plant-based foods, such as apples, mushrooms and wine.)

In the study, blood samples from new tea drinkers were 12 to E. coli, bacteria 13 food poisoning and ulcers. The 14 cells in the tea drinkers produced five times the interferon―an important element of the body's 15 system--than they had before tea was 16 .

1. 【答案】B

【解析】deterioration意思是“退化，堕落”，digestion意思是“消化”，destination意思是“目的地”，distinction意思是“区别”。根据上下文和关键词“digestive juices”，我们可以确定B是正确答案。

2. 【答案】B

【解析】other than的意思是“不同于，非”，rather than的意思是“不如说…而不是…”，better than的意思是“比…好”，more than的意思是“比…多”。chicken soup or echinacea是插入语，起到补充说明的作用，根据句子意思，B是正确答案。

3. 【答案】A

【解析】kick，kit，kite和kid的意思分别是“踢”，“成套工具，工具包”，“风筝”和“小孩”，kick另有“极度的刺激”之意，所以kick为正确选项。这句话的意思是:茶叶而不是鸡汤或海胆能为人体提供额外的刺激，帮助它对抗细菌。

4. 【答案】A

【解析】四个介词都可和fight搭配，fight off意思是“击退”，fight against和fight with的意思都是“和…战斗”，fight for意思是“为…而战斗”。fight against和fight with可以同时被排除，fight for也不对，因此答案是A。

5. 【答案】C

【解析】praise意思是“表扬”，acknowledge意思是“承认，答谢”，credit意思是“认为有某种优点”，create意思是“创造”。praise一般是口头赞扬，此处研究人员认为茶叶具有某种优点，用credit更正规、客观，所以选C。

6. 【答案】D

【解析】item意思是“条款，项目”，instance意思是“例子，建议”，information意思是“信息”，ingredient意思是“成分”。这里指的是绿茶、红茶、乌龙茶和白毫的某种共同成分，所以应选D。
