　　研究者們最近發(fā)現(xiàn)治療人類突發(fā)性疾病的藥對(duì)于延長人類的壽命也有幫助。研究者們對(duì)蛔蟲使用了這種藥，結(jié)果發(fā)現(xiàn)蛔蟲的壽命增加了50％。使用蛔蟲作為研究對(duì)象是非常有意義的，因?yàn)榛紫x在很多重要方面與人類都頗為相似，尤其是在基因和蛋白質(zhì)的構(gòu)成方面。研究中使用的藥物已經(jīng)在人類的實(shí)際生活中被使用過了，特別是抗癲癇藥。這種藥同樣也會(huì)增加蛔蟲的神經(jīng)肌肉活動(dòng)，研究者們認(rèn)為這種活動(dòng)與延緩衰老同樣有著某種聯(lián)系。

　　41. ［答案］E

　�。劢馕觯菘涨拔淖痔岢隽宋恼碌闹黝}，也就是概括性地介紹了文章的內(nèi)容："一項(xiàng)研究表明治療人類突發(fā)性疾病的藥物能延緩蟲子的衰老，由于人類的分子結(jié)構(gòu)與蟲子相似，所以有可能這種藥物也能延緩人類的衰老"。只有選項(xiàng)E繼續(xù)概括性地介紹了文章的內(nèi)容："這項(xiàng)研究同樣也表明神經(jīng)肌肉活動(dòng)與衰老有關(guān)系"。

　　42. ［答案］F

　�。劢馕觯菘涨拔淖指爬ń榻B了Evason的實(shí)驗(yàn)，只有選項(xiàng)F非常清楚地描述了實(shí)驗(yàn)對(duì)象，并說明為什么使用這個(gè)實(shí)驗(yàn)對(duì)象的原因。這實(shí)際上都是介紹實(shí)驗(yàn)的一部分。

　　43. ［答案］B

　�。劢馕觯菘涨拔淖忠恢碧岬綄�(shí)驗(yàn)的進(jìn)程和結(jié)果，選項(xiàng)B進(jìn)一步提到了這次實(shí)驗(yàn)的結(jié)果。同現(xiàn)原則，這一空的正確選項(xiàng)應(yīng)該是B。

　　44. ［答案］A

　�。劢馕觯菘涨拔淖痔岬剑�"有理由相信這種實(shí)驗(yàn)結(jié)論對(duì)更高級(jí)的動(dòng)物，如人類，也同樣適用"。所以這一空應(yīng)該繼續(xù)談到實(shí)驗(yàn)結(jié)果對(duì)人類究竟是不是適用的問題。選項(xiàng)A提到："但是科學(xué)家們目前還不知道究竟對(duì)人類是不是適用，除非也在人類身上做相同的實(shí)驗(yàn)"。顯然，選項(xiàng)A最合適。

　　45. ［答案］D

　�。劢馕觯菘涨拔淖痔岬搅肆硪粋�(gè)問題：神經(jīng)肌肉活動(dòng)與延緩衰老的問題；只有選項(xiàng)D繼續(xù)提到了這個(gè)問題，所以選D。

　　選項(xiàng)C：該選項(xiàng)指出："蛔蟲實(shí)際上并不是理想的實(shí)驗(yàn)對(duì)象，因?yàn)榛紫x不是人類，盡管兩者分子結(jié)構(gòu)相同。"顯然，這個(gè)選項(xiàng)與原文主旨完全背離。連實(shí)驗(yàn)對(duì)象都是錯(cuò)誤的話，文章的結(jié)論就更加不可能是正確的。這個(gè)選項(xiàng)應(yīng)該排除。

　　選項(xiàng)G：該選項(xiàng)指出："這種藥物已經(jīng)用于延緩人類衰老了，雖然還需要更多的證據(jù)來證明這種藥物真的會(huì)起作用"。這種論點(diǎn)顯然是不對(duì)的；沒有做過實(shí)驗(yàn)怎么能夠就冒然使用呢?而且與文中提到的"目前還沒有在人類身上做實(shí)驗(yàn)"這一點(diǎn)完全相左。這個(gè)選項(xiàng)也是明顯的干擾選項(xiàng)。

　　上周日，中國中央銀行行長周小川表示，如果有必要，中國將考慮擴(kuò)大人民幣的交易區(qū)間。

　　Dear Sir:

　　I read with interest your advertisement in the Communications of the A.C.M for the position of Director of the new Computer-Aided Learning Center being set up by Ray Conwell Co., Inc. RCC has a reputation for producing high-quality products such as the Mandolin Network System. I am interested in joining such a professional organization.

　　As you can see from the enclosed resume, my previous work has included supervision of software product development as well as extensive work in computer-aided learning. Although my educational training concentrated on theoretical computer science, my current interests lie more in applications of computer science principles to produce viable products.

　　My years of studying and teaching in the university setting have given me a good knowledge of pedagogical process. I look forward to the opportunity to apply this in the development of a state-of-the-art CAL system. My previous experience in systems design work makes me confident that I could make a valuable contribution to Ray Conwell Co., Inc.

　　I am looking forward to your reply.

　　Sincerely Yours,

　　From the pie chart we see health care expenditures in U.S.A in 1999, which consists of seven parts: hospital care, physician service, program administration and insurance costs, nursing care, dental service, drug and medical expenses and others.

　　As we may see from this chart, hospital care takes the greatest portion of the whole health care expenditures, accounting for 40% of the total sum. Physician services ranks the second, closely following hospital care, taking up 20% (＄110 billion) of the total sum of ＄550 billion. The other expenditures include nursing care, dental service, drug and medical expenses, program Administration and insurance costs, and other expenditures.

　　This chart shows clearly the Americans, just like people elsewhere in the world, take more attention to the welfare directly concerning their health: they spend a major part (60%) of their health care expenditures on hospital care and physician services. Nursing care ranks the third, preceding drug and medical expenses, which seems to be different from what exist in most third word countries, for example, in China, where drug and medical expenses account for a major part of the total health care expenditures. In my opinion, the labor force is much more expensive in the U.S. than in the third world countries, and that is why nursing care costs more than quite a few items do. (220 words)
