A potful of evidence suggests that the antioxidants and polyphenols in tea help protect you from stroke and heart attack, Alzheimer's disease, arthritis, and cancers of the lung, mouth, breast, pancreas, prostate and skin. The essential oils found in the leaves even aid 1 by increasing the flow of digestive juices.
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 . No change was noted in a 17 group of coffee drinkers.
“I don’tthink there’s a 18 to [drinking tea],” says co-author Jack F. Bukowski, M.D, of Harvard Medical School. While tea won’t 19 you or make you immune from illness, “people who do get sick will probably get a milder 20 ,” Bukowski says.

答案
1. 【答案】B
【解析】deterioration意思是“退化,墮落”,digestion意思是“消化”,destination意思是“目的地”,distinction意思是“區(qū)別”。根據(jù)上下文和關(guān)鍵詞“digestive juices”,我們可以確定B是正確答案。
2. 【答案】B
【解析】other than的意思是“不同于,非”,rather than的意思是“不如說(shuō)…而不是…”,better than的意思是“比…好”,more than的意思是“比…多”。chicken soup or echinacea是插入語(yǔ),起到補(bǔ)充說(shuō)明的作用,根據(jù)句子意思,B是正確答案。
3. 【答案】A
【解析】kick,kit,kite和kid的意思分別是“踢”,“成套工具,工具包”,“風(fēng)箏”和“小孩”,kick另有“極度的刺激”之意,所以kick為正確選項(xiàng)。這句話(huà)的意思是:茶葉而不是雞湯或海膽能為人體提供額外的刺激,幫助它對(duì)抗細(xì)菌。
4. 【答案】A
【解析】四個(gè)介詞都可和fight搭配,fight off意思是“擊退”,fight against和fight with的意思都是“和…戰(zhàn)斗”,fight for意思是“為…而戰(zhàn)斗”。fight against和fight with可以同時(shí)被排除,fight for也不對(duì),因此答案是A。
5. 【答案】C
【解析】praise意思是“表?yè)P(yáng)”,acknowledge意思是“承認(rèn),答謝”,credit意思是“認(rèn)為有某種優(yōu)點(diǎn)”,create意思是“創(chuàng)造”。praise一般是口頭贊揚(yáng),此處研究人員認(rèn)為茶葉具有某種優(yōu)點(diǎn),用credit更正規(guī)、客觀,所以選C。
6. 【答案】D
【解析】item意思是“條款,項(xiàng)目”,instance意思是“例子,建議”,information意思是“信息”,ingredient意思是“成分”。這里指的是綠茶、紅茶、烏龍茶和白毫的某種共同成分,所以應(yīng)選D。
7. 【答案】A
【解析】herbal意思為“草藥的”,credible意思是“可信的”,favorable意思是“贊成的,有利的”,fashionable意思是“流行的,時(shí)髦的”。從句子結(jié)構(gòu)可以看出,teas和前面的green tea等相對(duì)應(yīng),是一種茶葉,因此正確答案為A。
8. 【答案】D
【解析】product意思是“產(chǎn)品”,package意思是“包裹”,producer意思是“生產(chǎn)商”,plant意思是“植物”。從句子結(jié)構(gòu)看,the one true tea是Camellia(茶科)sinensis的同位語(yǔ),所以只能是tea plant(茶科植物),正確答案是D。
9. 【答案】A
【解析】根據(jù)句子結(jié)構(gòu)分析,此處是非限制性定語(yǔ)從句,修飾ethylamine,因此只能選which,正確答案為A。
10. 【答案】C
【解析】后面列舉了各種類(lèi)型的疾病,諸如細(xì)菌性、病毒性、真菌性和寄生性的,因此四個(gè)選項(xiàng)中最合適的是variety,C是正確答案。
11. 【答案】B
【解析】disease意思是“疾病”,infection意思是“傳染病”,illness也是“疾病”,deficiency意思是“缺乏,不足”。disease和illness是同義詞,同時(shí)排除,deficiency也不合適,所以選B。
12. 【答案】A
【解析】expose的意思是“使暴露”,oppose意思是“反對(duì)”,disclose意思是“揭露”,propose意思是“提出”。be exposed to意思是“使充分接觸”。本句意思是:在研究中,從新近開(kāi)始喝茶者身上提取血液樣本,讓他們的血液樣本和E. coli細(xì)菌充分接觸以觀察變化,正確答案為A。
13. 【答案】D
【解析】be connected with的意思是“和…連接”,be combined with意思是“和…組合”,be referred to意思是“被提及”,be linked to意思是“和…關(guān)聯(lián)”。這里指的是與食物中毒和潰瘍有關(guān)的細(xì)菌,link比其他幾個(gè)選項(xiàng)更合適,因此正確答案為D。
14. 【答案】D
【解析】immense意思是“極大的”,important意思是“重要的”,immediate意思是“立即的,直接的”,immune意思是“免疫的”。被選詞后搭配的詞是cell(細(xì)胞),聯(lián)系上下文的意思,此處應(yīng)選詞為immune,D為正確答案。
15. 【答案】B
【解析】defeat意思是“失敗”,defense意思是“保衛(wèi),防衛(wèi)”,decrease意思是“減少”,disease意思是“疾病”?崭窈竺娴拿~是system,它是人體的一個(gè)系統(tǒng),顯然只能選defense,正確答案為B。
16. 【答案】A
【解析】introduce意思是“介紹,引進(jìn)”,increase意思是“增加”,indulge“縱容”,indicate意思是“顯示,指出”。此處將喝茶前后人體反應(yīng)進(jìn)行對(duì)照,before引導(dǎo)時(shí)間狀語(yǔ)從句,從句中的主語(yǔ)是tea,因此正確選項(xiàng)為A。
17. 【答案】B
【解析】一般做實(shí)驗(yàn)會(huì)把實(shí)驗(yàn)對(duì)象分為兩組,一組是實(shí)驗(yàn)組“experimental group”,另外一組是對(duì)照組“control group”。正確答案為B。
18. 【答案】A
【解析】downside的意思是“消極的一面,負(fù)面”,upside是“上面,上部”,inside是“里面,內(nèi)側(cè)”,outside是“外面,外表”。四個(gè)選項(xiàng)中只有downside符合句子意思,正確答案為A。
19. 【答案】C
【解析】四個(gè)選項(xiàng)為同義詞,都有“治療”的意思。heal為“愈合”,偏重于外傷。treat為“治療”,指治療的過(guò)程。cure意思是“治愈”,指結(jié)果。remedy意思是“醫(yī)治,治療,矯正’。本句中you和make you immune from illness是并列的,cure是最合適的選項(xiàng),答案是C。
20. 【答案】D
【解析】illness,disease和sickness是同義詞,都有“病”的意思,case指的是“病癥”,因?yàn)榍懊嬗衜ild修飾,而且前三個(gè)選項(xiàng)之間無(wú)法取舍,因此正確答案是D。
