下面有．3篇短文，每篇短文后有5道题，每题后面有4个选项。请仔细阅读短文并根据短文回答其后面的问题，从4个选项中选择1个最佳答案。
第一篇
Volunteers are being recruited(征募) to eat raw potatoes in the first human trials of a vaccine grown in genetically engineered vegetables. Researchers in Texas hope that people who eat the potatoes will be protected against common gut(肠，肠子) infections. They believe this technique could prove to be a cost-effective way of growing vaccines in developing countries where such diseases are still killers.
Other researchers previously succeeded in using similar techniques to produce potential vaccines Now Hugh Mason and his colleagues at Texas A & M University(得克萨斯农业及机械大学) their plant vaccines on mice and plan to recruit 15 volunteers for a human trial.
The team first tested the technique in tobacco plants. They took a strain of Escherichia coli(大肠杆菌) bacteria that causes food poisoning, and identified the part of the poison which binds to its victims gut cells. They then used a modified plant bacterium called Agrobacterium tumefasciens to transfer the segment of DNA which manufactures the binding protein into the tobacco plant. Under normal circumstances, these bacteria transfer packets of DNA into plant cells to force the plant to manufacture the nutrients they need. But in the modified bacteria, the DNA package includes the gene to pro- duce the binding protein.
Once the foreign DNA segment was incorporated(结合，合并) into the tobacco's own DNA, the bacteria were killed off with antibiotics. Mason's team then grew these modified tobacco plants and found that they produced the E. coli binding protein.
Proof of success came when the tobacco leaves were mashed up(捣碎) and squirted into the stomachs of mice. Mason says that within days the mice started producing specific antibodies to the E. coli poison, but suffered no ill effects from digesting the binding protein. Mason then produced genetically engineered potatoes and fed these to mice, with similar results.
Mason's team have used plants to produce vaccines against a number of other infectious agents. For example, they have made a vaccine using a protein from the shell of the Norwalk virus, which causes diarrhoea(腹泻) in children.
A third vaccine has also been produced in tobacco using a surface protein from the hepatitis B virus. But Mason says that so far they have only been able to produce small amounts of it in potatoes. Although a vaccine already exists against hepatitis B, a cheaper plant version could make mass immunisation(群众性免疫) possible.
One problem with growing potatoes to produce vaccines is that cooking tends to destroy the protein component of the vaccine, so they must be eaten raw. Mason thinks that bananas may be a better option. "One banana could potentially produce a whole host of different vaccines," says Mason.
The purpose of this text is______。
A. to prove that doctors don't like vegetables
B. to amuse the reader by telling some funny things
C. to describe how vegetables can grow vaccines for their own use
D. to tell the reader about a cheaper way of growing vaccines

阅读下面的文章，回答41—45题。关于“韦编三绝”
“韦编三绝”是说孔子读《易》次数之多，竞把编联简册的编绳翻断了多次。此语最早见于《史记．孔子世家》。 对“韦编”的“韦”如何理解？新版《辞海》的解释是：“韦，熟牛皮。古代用竹简写书，用皮绳编缀，故日韦编。”这种说法其实是错误的。其一，现代的形声字古代常常写作假借字．汉代文献中此例不胜枚举。汉代许慎《说文》有“经，织从丝也”。许慎所用的“从”，即今之形声字“纵”字的假借字。我们既知“纵”字在汉代实写作“从”，那么我们把汉人(司马迁)写的“韦编”读作“纬编”是合乎汉人用字常理的。纬编即编联简册的纬绳。因为古人常把纵横称作经纬，所以《说文》又称“纬，织横丝也”。简书的竹简是纵向排列的，犹如织布帛的经线，编联简册的组绳则是横向编联的，犹如织布帛的纬线。据此，把横向编联简册的组绳称作“纬绳”、“编纬”是理所当然的。其二，古代简书并不一定是用皮绳编缀的。陈梦家在《汉简缀述》中写道：“所用以编简札为册者，多为丝纶。有时写作‘编’。”荀勖《穆天子传》记“燕郡魏冢所出‘皆竹简素丝编’，《南齐书•文惠太子传》记襄阳古冢所出《考工记》‘竹简书，青丝编……’居延出土汉简册”，则用麻绳。”毫无疑问，所谓“素丝编”“青丝编”都是指的丝绳。出土简册，则木简仅见用麻绳。 除了“韦编三绝”的“韦”被译为皮绳外，尚不见任何关于用皮绳编联简册的的记载和实物。
第41题：
作者认为《辞海》对“韦编三绝”的“韦”字解释有误，不能支持这一观点的依据是（）。
A．孔子读《易》，竟然多次翻断了简策的编绳
B．把横向编联简册的组绳称作“纬绳”、“韦编”是理所当然的
C．既然“纵”字在汉代实写作“从”，那么把“韦编”写作“纬编”是合理的
D．因为古人常把纵横称作经纬，所以纬(韦)编即编联简册的纬绳

下面的短文后有2项测试任务：（1）第23～26题要求从所给的6个选项中为第2～5段每段1选择个最佳标题；（2）第27～30题要求从所给的6个选项中为每个句子确定1个最佳选项。
Money or Friendship or Both
1 Friends and money don't mix. It's a dangerous combination since a fight over money is one of the fastest ways to end a friendship. But what if a friend asks you to lend him or her some money？ If you don't lend your friend the money, you risk losing the friend If you do lend your friend the money, you risk losing both the friendship and your money
2 We have to face facts, so here are some situations you might run across with your buddies (伙伴) - and some helpful tips (忠告) on how to deal with them. Think about why this person needs to borrow in the first place. If he is always living beyond his means, it's his fault, not yours. Any sensible person would not put himself in a position of debt so often. So simply say "no" to this friend. Even if your friend really needs that money for emergency use and you are willing to help him, before you dived into your pocket, follow this reality check: Do you have the extra money？ Are you sure you don't need it？ Are you willing to write off that amount if it's not returned？ If your answers are negative, do yourself a favor and say "no".
3 Let's assume you can't stand saying "no" to your friend because you don't want him living off cat food. What do you do？ Write down these details on a sheet of paper before opening up your wallet:
Amount of the loan.
Date of the loan.
Time of repayment.
Amount of interest (if any).
Lender's and borrower's signature.
This will at least keep the borrower from forgetting the loan so easily. If your friend's loan is past due, it's important that you ask him - and it's actually not rude. The longer you wait, the more you brood (忧伤), and the more your resentment builds.
4 You can send him a friendly reminder via e-mail. Tell him something like 'Tm going over my bank account and I'm just wondering when we'll be able to settle that money thing." E-mail saves you from an uncomfortable face-to-face confrontation. There is almost no chance of turning a bad reaction into an argument. Unlike a public conversation, an e-mail message will always be private.
5 After asking two or three times, you might have to wnte it off and the friendship with it. That's what happens. If he just doesn't have the money or is unwilling, then what kind of friend is that？
23 Paragraph 2 .
24 Paragraph 3 .
25 Paragraph 4 .
26 Paragraph 5 .
A Time to break off a friendship
B Unconditional assistance to friends in need
C Things to consider when you have to say "no" to your friend
D Things to think over when you don't want your friend to eat cat food
E Strategies for borrowing money
F Advantages of e-mail in handling money issues

Understanding Autism
1 Autism (孤独症) is a life-long developmental disability that prevents individuals from properly understanding what they see, hear, and otherwise sense. This results in severe problems of social relationships, communication, and behavior. Individuals with autism have to painstakingly '(费力地) learn normal patterns of speech and communication, and appropriate ways to relate to people, objects, and events, in a similar manner to those who have had a stroke.
2
The cause of autism is still unknown. Some research suggests a physical problem affecting those parts of the brain that process language and information coming in from the senses. There may be some imbalance of certain chemicals in the brain. Genetic (遗传的) factors may sometimes be involved. Autism may indeed result from a combination of several "causes".
3 Most people with mental retardation (智力迟钝的)show relatively even skill development. Individuals with autism, however, typically show uneven skill development, with deficits (~欠缺) in certain areas - most frequently in their ability to communicate and relate to others - and distinct skills in other areas. It is important to distinguish autism from mental retardation or other disorders, since diagnostic (诊断的) confusion may lead to inappropriate and ineffective treatment techniques.
4 In general, individuals with autism perform. best at jobs which are structured and involve a degree of repetition. Some people who have autism are working as artists, piano tuners, painters, farm workers, office workers, computer operators, dishwashers, assembly line workers, or employees of sheltered workshops or other sheltered work settings.

Even Intelligent People Can Fail
1 The striking thing about the innovators who succeeded in making our modern world is how
often they failed．Turn oil a light，take a photograph，watch TV,search the web，jet across the
Pacific Ocean．talk on a cellphone(手机)．The innovators who left us these things had to find the
way to success through a maze(错综复杂)of wrong turns．
2 We have just celebrated the 125th anniversary of American innovator Thomas Edison’s
success in heating n thin line to white，hot heat for 14 hours in his lab in New Jersey，US．He did
that on October 22．1879．and followed up a month later by keeping a thread of common
cardboard alight(点亮着的)in an airless space for 45 hours．Three years later he went on to light
up half a square mile of downtown Manhattan，even though only one of the six power plants in
his design worked when he turned it on，on September 4，1882．
3 “Many of 1ife’S failures”the supreme innovator said．“are people who did not realize how close they were to success when they gave up”Before that magical moment in October 1879．
Edison had worked out no fewer than 3．000 theories about electric light．But in only two cases did
his experiments work．
4 N0 one likes failure，but the smart innovators learn from it．Mark Gumz．the head of the
camera maker Olympus America Inc．attributes some of the company’S successes in technology
to understanding failure．His popular phrase is：“You only fail when you quit”
5 0ver two centuries,the most common quality of the innovators has been persistence That is
another way of saying they had the emotional ability to keep up what they were doing．Walt
Disney,the founder of Disneyland，was so broke after a succession of financial failures that he
was left shoeless in his office because he could not afford the US$1．50 to get his shoes from the
repair shop．Pioneering Car maker Henry Ford failed with one company and was forced out of
another before he developed the Model T Car．
6 Failure is harder to bear in today’s open,accelerated world．Hardly any innovation works
the first time But an impatient society and the media want instant success When American
music and movie master David Geffen had a difficult time，a critic said nastily that the only
difference between Geffen Records (Geffen’s company)and the Titanic(the ship that went down) was that the Titanic had better music．Actually，it wasn’t．After four years of 10sses．Geffen had so many hits(成功的作品)he could afford a ship as big as the Titanic all to himself．

Fruit
Imagine a world without fruit. We wouldn’t be very healthy. We get a lot of important vitamins from eating fruit.
We think of fruit primarily as something to eat. (1) Fruit is part of a flowering plant and it carries the seeds. The purpose of fruit is to protect a plant's seeds and help them get spread about. Wind and water spread seeds. So do animals when they eat fruit and drop the seeds. (2) There are two main types of fruit fleshy and dry. Fleshy fruits are soft and juicy. Pears, bananas and apples are all fleshy fruits. (3) Grains like wheat and rice, or nuts like chestnuts(板栗) ,are dry fruits.
But wait You’ve eaten oranges and grapes without seeds. How can they be fruits？ It's because people have changed the way they grow fruit. They can now grow seedless fruit. Seedless fruit comes from special plants that are made by combining two varieties of a fruit to form. a new variety. These special plants grow and produce seeds. (4) These plants cannot reproduce themselves. They can make fruit, but the fruit has no seeds.
Fruits are a source of substances that keep us alive and healthy. So people make use of fruits for many foods. We make juices from them. We make jams and sweets.(5) Beer comes from grains and wine comes from grapes, and some particular wines are made from apples, peaches, or other fruits.
A. Dry fruits are thin and hard.
B. We even make alcohol from fruit.
C. But fruit has a purpose quite apart from our needs.
D. So these plants produce fleshy fruits.
E. Then the seeds grow into new plants.
F. But the plants grown from these seeds are seedless.

阅读下面的文字，完成 7～10 题。
在生物经济时代，基因不是金钱，但胜过金钱。洛克菲勒大学有一条肥胖基因，售价高达2000万美元。由于经济利益的驱动，已有2000个“功能已知的基因”被授予专利。这样，受谴责的“基因专利”便获得公认，迫使人们改变原来的伦理观念，不得不参加“基因争夺战”。因为人类基因组的基因总数是有限的，毕竟只有6万-10万个。每当一个基因获专利，就等于拥有了一个基因。于是，人们为了专利而抢夺基因。特别是我国的基因资源，常常无偿地被国外掠夺，丧失知识产权，连当事人也不知道。因此，我们只有参与竞争去争取。人类只有一个基因组，每个人的基因有99．9％是相同的，说明人类大家庭所有成员的统一性，是人之为人的根据；另有0．1％是不同的，说明每个成员的差异性，是人与人又有不一样的依据。但是，这种差异并非表明基因有优劣之分，所有均基因都是平等的，各有各的用处，即便是缺损的基因，也有其特殊功能。少数白种人(约为l％一5％)在一个基因中，有31个核苷酸的缺陷，使之能抵抗艾滋病病毒的感染。因此，依据人类基因的统一性，应该人人平等，不应有基因歧视；依据人类基因的差异性，应该尊重个人权利，享有基因隐私权。“人类基因组计划”的目的，就是要测定人类基因的全部DNA序列，最终破译人体的遗传密码，揭示人类生命的奥秘。一旦完全掌握了人体遗传密码，就意味着人类同时获得了重新设计自己的能力。由此引发“伦理炸弹”：人要代替上帝创造人吗？基因也会如同零件一样而被任意组装成“品牌婴儿”吗？人还能称之为人吗？人的尊严在哪里？人性又在哪里？人不是上帝，也没有上帝，只能靠自己掌握自己前进的方向，再也不能等待自然的恩赐。虽然人类处于自然进化的顶层，但并非尽善尽美，而且自然的进化十分缓慢。现在，世界各地的不育现象成为严重问题，却又被世界人口大幅度增长所掩盖。同时，人工智能促进机器智能逼近人类智能的发展，生物工程加速其他物种的人工进化。如果人类不改变自己，特别是不加速智力的人工进化，在不远的将来，就会遭遇人造新物种和机器高智能的双重挑战，难免优胜劣汰。人类要想立于不败之地，就得将基因技术与智能技术结合起来，形成新的智力技术，对人进行基因设计，特别是脑的设计，展现人的价值，尤其是高智能的价值。这种高智能价值，正是伦理选择的依据。
