Not long ago, a mysterious Christmas card dropped through our mail slot. The envelope was addressed to a man named Raoul, who, I was relatively certain, did not live with us. The envelope wash' t sealed, so I. opened it. The inside of the card was blank. Ed, my husband, explained that the card was both from and to the newspaper deliveryman. His name was apparently Raoul, and Raoul wanted a holiday tip. We were meant to put a check inside the card and then drop the envelope in the mail. When your services are rendered at 4 a. m. , you can' t simply hang around, like a hotel bellboy expecting a tip. You have to be direct.
So I wrote a nice holiday greeting to this man who, in my imagination, fires The New York Times from his bike aimed at our front door, casing more noise with mere newsprint than most people manage with sophisticated black market fireworks.
With a start, I realized that perhaps the reason for the 4 a.m. wake-up noise was not ordinary rudeness but carefully executed spite: I had not tipped Raoul in Christmases past. I honestly hadn't realized I was supposed to. This was the first time he'd used the card tactic. So I got out my checkbook. Somewhere along the line, holiday tipping went from an optional thank-you for a year of services to a Mafia-style protection racket (收取保護費的組織).
Several days later, I was bringing our garbage bins back from the curb when I noticed an envelope taped to one of the lids. The outside of the envelope said MICKEY. It had to be another tip request, this time from our garbage collector. Unlike Raoul, Mickey hadn't enclosed his own Christmas card from me. In a way, I appreciated the directness. "I know you don' t care how merry my Christmas is, and that' s fine, " the gesture said. "I want $ 30, or I'll ‘ forget' to empty your garbage bin some hot summer day. "
I put a check in the envelope and taped it back to the bin. The next morning, Ed noticed that the envelope was gone, though the trash hadn't yet been picked up: "Someone stole Mickey' s tip !" Ed was quite certain. He made me call the bank and cancel the check.
But Ed had been wrong. Two weeks later, Mickey left a letter from the bank on our steps. The letter informed Mickey that the check, which he had tried to cash, had been cancelled. The following Tuesday morning, when Ed saw a truck outside, he ran out with his wallet. “Are you Mickey?”
The man looked at him with scorn. "Mickey is the garbageman. I am the recycling. " Not only had Ed insul- ted this man by hinting that he was a garbageman, but he had obviously neglected to tip him. Ed ran back inside for more funds. Then he noticed that the driver of the truck had been watching the whole transaction. He peeled off an- other twenty and looked around, waving bills in the air. "Anyone else?"
Had we consulted the website of the Emily Post Institute, this embarrassing broach of etiquette (禮節) could have been avoided. Under "trash/recycling collectors" in the institute' s Holiday Tipping Guidelines, it says, " $10 to $30 each. " You may or may not wish to know that your pet groomer, hairdresser, mailman and UPS guy all expect a holiday tip.

A. he forgot to write a few words on it
B. he wanted the couple to send it back
C. he used it to ask for a Christmas tip

At 18, Ashanthi DeSilva of suburban Cleveland is a living symbol of one of the great intellectual achievements of the 20th century. Born with an extremely rare and usually fatal disorder that left her without a functioning immune system (the "bubble-boy disease", named after an earlier victim who was kept alive for years in a sterile plastictent), she was treated beginning in 1990 with a revolutionary new therapy that sought to correct the defect at its very
source, in the genes of her white blood cells. It worked. Although her last gene-therapy treatment was in 1992, she is completely healthy with normal immune function, according to one of the doctors who treated her, W. French Anderson of the University of Southern California. Researchers have long dreamed of treating diseases from hemophilia to cancer by replacing mutant genes with normal ones. And the dreaming may continue for decades more.
"there will be a gene-based treatment for essentially every disease, " Anderson says, "within 50 years. "
It' s not entirely clear why medicine has been so slow to build on Anderson' s early success. The National Insti- tutes of Health budget office estimates it will spend $ 432 million on gene-therapy research in 2005, and there is no shortage of promising leads. The therapeutic genes are usually delivered through viruses that don' t cause human disease. "The virus is sort of like a Trojan horse, " says Ronald Crystal of New York Presbyterian/Weill Cornell Medical College. "The cargo is the gene. "
At the University of Pennsylvania' s Abramson Cancer Center, immunologist Carl June recently treated HIV patients with a gene intended to help their cells resist the infection. At Cornell University. researchers are pursuing gene-based therapies for Parkinson' s disease and a rare hereditary disorder that destroys children" s brain cells. At Stanford University and the Children' s Hospital of Philadelphia, researchers are trying to figure out bow to help pa- tients with hemophilia who today must inject themselves with expensive clotting drugs for life. Animal experiments have shown great promise.
But somehow, things get lost in the translation from laboratory to patient. In human trials of the hemophilia treatment, patients show a response at first, but it fades over time. And the field has still not recovered from the set- back it suffered in 1999, when Jesse Gelsinger, an 18-year-old with a rare metabolic disorder, died after receiving an experimental gene therapy at the University of Pennsylvania. Some experts worry that the field will be tarnished fur- ther if the next people to benefit are not patients but athletes seeking an edge. This summer, researchers at the Salk Institute in San Diego said they had created a "marathon mouse" by implanting a gene that enhances running ability;already, officials at the World Anti-Doping Agency are preparing to test athletes for signs of "gene doping". But the principle is the same, whether you' re trying to help a healthy runner run faster or allow a muscular-dystrophy patient to walk. "Everybody recognizes that gene therapy is a very good idea, " says Crystal. "And eventually it' s going to work. ""
56. The case of Ashanthi Desilva is mentioned in the text to
A. show the promise of gene-therapy
B. give an example of modern treatment for fatal diseases
C. introduce the achievement of Anderson and his team
D. explain how gene-based treatment works
57. Anderson' s early success has ____
A. greatly speeded the development of medicine
B. brought no immediate progress in the research of gene-therapy
C. promised a cure to every disease
D. made him a national hero
58. Which of the following is true according to the text?
A. Ashanthi needs to receive gene-therapy treatment constantly.
B. Despite the huge funding, gene researches have shown few promises.
C. Therapeutic genes are carded by harmless viruses.
D. Gene-doping is encouraged by world agencies to help athletes get better scores.
59. The word "tarnish" (line 4, paragraph 4) most probably means __
A. affect
B. warn
C. trouble
D. stain
6O. From the text we can see that the author seems
A. optimistic
B. pessimistic
C. troubled
D. uncertain

Shortages of flu vaccine are nothing new in America, but this year' s is a whopper. Until last week, it appeared that 100 million Americans would have access to flu shots this fall. Then British authorities, concerned about quality-control problems at a production plant in Liverpool, barred all further shipments by the Chiron Corp. Overnight, the U. S. vaccine supply dwindled by nearly half and federal health officials found themselves making an unusual plea. Instead of beseeching us all to get vaccinated, they' re now urging most healthy people between the ages of 2 and 64 not to. "This reemphasizes the fragility of our vaccine supply, " says Dr. Martin Myers of the National Network for Immunization Information, "and the lack of redundancy in our system.
Why is such a basic health service so easily knocked out? Mainly because private companies have had little in. centive to pursue it. To create a single dose of flu vaccine, a manufacturer has to grow live virus in a 2-week-old fertilized chicken egg, then crack the egg, harvest the virus and extract the proteins used to provoke an immune response. Profit margins are narrow, demand is fickle and, because each year' s flu virus is different, any tettover vaccine goes to waste. As a result, the United States now has only two major suppliers ( Chiron and Aventis Pas- teur)--and when one of them runs inla trouble, there isn' t much the other can do about it. "A vaccine maker can" t just call up and order 40 million more fertilized eggs, " says Manon Cox, of Connecticut-based Protein Sciences Corp. "There' s a whole industry that' s scheduled to produce a certain number of eggs at a certain time. "
Sleeker technologies are now in the works, and experts are hoping that this year' s fiasco will speed the pace of innovation. The main challenge is to shift production from eggs into cell cultures--a medium already used to make most other vaccines. Flu vaccines are harder than most to produce this way, but several biotech companies are now pursuing this strategy, and one culture-based product ( Solvay Pharmaceuticals' Invivac) has been cleared for marketing in Europe.
For Americans, the immediate challenge is to make the most of a limited supply. The government estimates that 95 million people still qualify for shots under the voluntary restrictions announced last week. That' s nearly twice the number of doses that clinics will have on hand, but only 60 million Americans seek out shots in a normal year. In fact, many experts are hoping the shortage will serve as an awareness campaign--encouraging the people who really need a flu shot to get one.
61. Shortages of flue vaccine show that'
A. America relies too much cn foreign suppliers
B. the demand of flu vaccines is high this year
C. quality problem is a serious problem in flu vaccine production
D. the supply of flu vaccines is rather weak and America has no back-up measures to make it up
62. The word "cleared" ( Line 4, Paragraph 3) might mean
A. permitted
B. removed
C. proved
D. produced
63. Private companies have little interest in producing flu vaccines because of _____
A. complicated process, high cost, low profit and high risk
B. shortages of fertilized chicken eggs
C. difficulty in growing live virus
D. fast changing of flu virus
64. From the last paragraph we can infer that _
A. the government hopes to solve the problem by way of volunteer restrictions
B. more than 47 million Americans who are qualified to get flu vaccine shots can not get them this year
C. America has to deal with a limited supply of flu vaccines this year
D. normally only a small percentage of American population gets flu vaccine shots each year
65. According to the passage, which of the following is TRUE?
A. All Americans are persuaded not to get vaccinated this year.
B. The big problem in innovating flu vaccine producing technique is how to grow virus in a new way.
C. More flu vaccines can not be produced in a short time because private companies refuse to produce more.
D. Flu vaccines are easier than most vaccines to produce through cell cultures.

短文賞析
本文講的是卡片戰術的故事。不久以前，一封神祕的聖誕卡片投遞到了主人公郵箱裡。但是信封上的收信人不是和他們居住在一起的人!這張空卡片是送報人的，他想要假期小費。他們被暗示：要填好卡片投遞。所以女主人拿出支票單。無論在哪，因服務一年而給的假期小費已經發展成為了的保護勒索。幾天之後，女主人拿回垃圾筒時又收到了一封小費請求信，這次是他們家的垃圾回收員，他們沒有辦法.只好再次奉上，這次還鬧出了小小的誤會，讓男主人很無奈。面對這樣的窘境，夫婦倆去有關機構尋求幫助，其實假期小費早就已經是大家都遵行的“潛規則”了。
答案及解析
51.C【解析】由第一段可知，這張卡片是送報人的，我們被暗示：要填好卡片投遞，當你的服務在凌晨四點就被奉上時，你不能若無其事，你必須要直接點，他想要的是假期小費。因此正確答案為C。
52.A【解析】第二段中女主人寫了一封漂亮的假期賀詞給這個她從來沒看到或遇到過的人。這個人在她的想象裡就是像射擊一樣把《紐約時報》發射到她家門前，製造的噪聲要大於人們從黑市購得的鞭炮的聲響。所以她確實不喜歡拉烏爾投遞報紙的這種方式。因此正確答案為A。
53.D【解析】在第三段中女主人公意識到也許在四點的粗魯服務的原因是經過精心策劃的而不是習慣，假期小費從隨意的一句謝謝發展成為的保護勒索，所以作者是被迫給假期小費的。因此正確答案為D。
54.B【解析】從第五段中描述到，看到裝著支票的信封沒有了，但是垃圾還在，所以作者的丈夫懷疑信封是被別人偷走了，立馬就通知銀行作廢了這張支票。所以Mickey最終還是沒有從銀行中取走錢。因此正確答案為B。
55.A【解析】第六段中男主人看到清理垃圾的車，誤以為是Mickey來了，正要出去澄清誤會，把上次的小費補上，卻遭到了回收員的蔑視，所以他感到澄清誤會的機會是很渺茫了，對於假期小費的事情他已經絕望了。因此正確答案為A。

本篇文章是說明文，主要說明基因療法的前景、現狀、遭遇的問題以及人們對待基因療法的態度。文章第一段以上世紀90年代一次成功的基因治療為例說明基因療法的廣闊前景。第二段介紹了基因療法的現狀和治療機制。第三段介紹了目前用基因療法治療多種疾病的研究情況。第四段介紹了基因療法遭遇的問題以及人們對基因療法的態度。
答案及解析
56.A【解析】文章第一句話對用基因療法治療Ashanthi所患罕見疾病的成功給予了很高的評價，並在第一段末指出醫生們對基因療法寄予了極高的期望。因此正確答案為A。
57.B【解析】文章第二段一開頭就說：…It S not entirely clear whv medi—cine has been SO slow to build on Anderson’S early Success.”從時間上來看，Anderson採用基因療法的成功嘗試已經是l990年的事情了，兩相對照，可見他的成功沒有讓醫學加速發展。因此正確答案為B。
58.c【解析】文章第二段對於基因治療的方式的解釋是用於治療的基因通過“viruses that don’t cause human disease”進入體內，就好像“特洛伊木馬”一樣，由此可見，這些病毒是無害的。因此正確答案為C。
59.D【解析】第四段提到基因療法遭受的一起挫折——一個病人因接受基因療法而死亡;接著講專家擔心運動員利用基因在比賽中作弊會進一步tarnish這一領域，從上下文邏輯推理，應該是“有損，玷汙”這一類的意思，因此正確答案為D。
60.A【解析】作者的態度從文章第一句話和最後一句話就可以明顯判斷出來。第一句話說基因療法是20世紀的偉大成就之一，最後一句話說“Everybody recogllizes that gene therapy is a very good idea”，由此可見作者對基因療法持積極樂觀的態度。因此正確答案為A。

本篇文章探討了美國流感疫苗短缺事件，經濟成因以及當前與未來的解決辦法。第一段，作者介紹了美國流感疫苗短缺問題以及其直接原因，由於質量控制等問題，英國當局禁止向美國運輸疫苗，從而導致疫苗嚴重短缺，使疫苗供應量減少了近一半。於是聯邦衛生部門的官員敦促2至64歲的健康公民不要注射疫苗;第二段中，作者剖析了其背後的經濟原因;在第三段裡，作者介紹瞭解決短缺問題的辦法之一：革新疫苗生產技術，將其從受精卵中轉移到細胞培養。第四段中，作者探討了美國的當務之急：如何利用好有限的疫苗。出路就是號召公民發揚風格，將注射疫苗的機會讓給敏感群體，讓那些真正需要的人能夠接種疫苗。
答案及解析
61.D【解析】第一段最後一句話指出了疫苗短缺所暴露出來的'問題。
“This reemphasizes the fragility of our vaccine supply.”says in Myers of the National Network for Immunization Informa- tion，“and the lack of redundancy in our system.…‘這再次凸顯出我們疫苗供應的脆弱性，”全國免疫資訊網的馬丁-邁爾斯醫生說，“此外，我們也沒有必要的補救機制。”因此正確答案為D。
62.A 【解析】在第三段最後一句“…one d product has been cleared for marketing in Europe.”裡出現了“cleared”一詞。根據下文中“marketing”和讀者有關藥品上市前應該得到批准的常識，可以判斷出，該詞在本句中的意思是“得到官方的批准”。因此正確答案為A。
63.A 【解析】第二段第二句“Mainly because private companies have had little incentive to pursue it.”意思是說“私企生產流感疫苗的積極性不高”。接下來作者介紹了製作疫苗的複雜工序，由此可以推斷出流感疫苗生產工藝複雜、成本高。第二段又明確指出了私企不願意生產流感疫苗的其他原因：利潤率低、需求不穩定，此外由於流感病毒每年都不同，因此生產數量不能過大，由此也可推斷出生產的風險性大，如果生產多了就會損失很大。因此正確答案為A。
64.B【解析】由第四段第二句“The government estimates that 95 million people still qualify for shots under the voluntary restricfions an—nounced last week.”中可以知道大約有九千五百萬人有資格注射疫苗。根據第四段第三句：“That’S nearly twice the number of doses that clinics will have on hand，but only 60 million Americans seek out shots in a normal year.”和前一句可以推斷出美國現有大約四千七百萬份流感疫苗庫存，由此可推斷出美國至少還有四千七百多萬有資格注射疫苗的人無法得到注射。因此正確答案為B。
65.B 【解析】由第一段的“Instead of beseeching us all to get ’re now urging most healthy people between the ages of 2 and 64 not to.”可以判斷出美國之呼籲2至64歲的健康人不接種流感疫苗，而不是所有的美國人，因此答案A是錯誤的。從第二段最後一句話可以看出疫苗生產廠家無法臨時增加疫苗生產不是由於他們不願意，而是由於受精雞蛋的生產已經預先計劃好，無法提供更多的受精雞蛋，由此可見答案C是錯誤的。從第三段第三行“Flu vaccines ale harder than most to produce this way”可以判斷出答案D是錯誤的，因為流感疫苗比別的疫苗更難用細菌培育的方式生產。而由第三段第2—3行“The main challenge is to shift production from eggs into cell cultures——a medium already used to make most other vaccines.”以及上一句可見，改造疫苗生產工藝的關鍵在於革新病毒培育技術。因此正確答案為B。
