题目内容
【小题1】Painkillers in a tablet can make your headache go away. Antibiotic cream(抗生膏)from a tube can prevent your cuts from becoming infected. But can medicine come packaged in chicken eggs?
A team of scientists from Scotland says yes. They've engineered special chickens that lay eggs with disease -treating drugs inside.
【小题2】Animals make thousands of proteins—they’re the main ingredient in skin, hair, milk, and meat. Since animals can make proteins easily, they’re good candidates for making protein drugs.
Researchers have already made cows, sheep, and goats that pump out protein drugs in their milk. But chickens are not expensive to take care of; what’s more, they need less room, and grow faster than these other animals. “【小题3】”says Simon Lillico of the Roslin Institute near Edinburgh, Scotland.
Lillico and a team of researchers changed chickens’ DNA—the code that tells cells how to make proteins so that the birds’ cells made two protein drugs. 【小题4】
The scientists altered the chickens’ DNA so that the birds made these drugs only in their egg whites (蛋清). This protects the chickens’ bodies from the drugs’ possible harmful effects and makes it easy for scientists to collect the drugs.
These special chickens can pass on their drug-laying abilities to their chicks. 【小题5】The scientists need to improve these chickens before they roost (栖息) in drug companies’ labs. The birds don’t make enough drugs to treat people yet. But once the researchers perfect their technique, you might eventually take your medicine sunny-side up.
| A.Medicine comes in lots of different uses. |
| B.Those qualities could make chickens a better choice to become living drug factories. |
| C.So far, the Scottish researchers have bred five generations of drug—producing birds. |
| D.Some chickens are found having the ability of treating diseases. |
F. These drugs are made of molecules called proteins.
G. Medicine comes in lots of different packages.
【小题1】G

解析试题分析:这是一篇科技类阅读。一组来自苏格兰的科学家说可以。他们研制出一种特殊的鸡。这种鸡生的蛋里面含有治病药品。这些药品都来自于那些经设计后能在其蛋白中产出某些药品的鸡。这些药品都是由叫做蛋白质的分子构成的。
【小题1】根据后文Painkillers in a tablet can make your headache go away. Antibiotic cream from a tube can prevent your cuts from becoming infected. But can medicine come packaged in chicken eggs? 片剂类止痛药能消除你的头痛。装在管子中抗生素膏能预防你伤口感染。但药品能装在鸡蛋中吗?可知这里应该是:药品有不同的包装。故选G。
【小题2】根据后句Animals make thousands of proteins动物能产生很多的蛋白质。可知这里应该是These drugs are made of molecules called proteins.这些药是由叫蛋白质的成分构成。故选F。
【小题3】根据前文But chickens are not expensive to take care of; what’s more, they need less room, and grow faster than these other animals.但是鸡饲养成本更低,而且所需空间较小,生长较其它动物快。所以这里应该是:Those qualities could make chickens a better choice to become living drug factories鸡的这些特性使之成为转化成活性药品工厂的最佳选择。故选B。
【小题4】根据前文the birds’ cells made two protein drugs这样鸡的细胞就能产生两种蛋白质药品。可知接着要说明这两种蛋白质,故用One drug can treat skin cancer, and the other treats a nerve disease called multiple sclerosis一种治疗癌症,另一种治疗叫做多样硬化的神经方面的疾病。故选E。
【小题5】根据后文The scientists need to improve these chickens before they roost (栖息) in drug companies’ labs在这些鸡进入药厂的实验室之前,科学家还得对这些鸡进行改善。可知这里应该是:So far, the Scottish researchers have bred five generations of drug—producing birds.到现在为止,苏格兰科学家已经五种生产药品的鸟。故选C。

Hospital emergency rooms treat injured fingers all the time. Without treatment, a bad cut can lead to permanent damage. But how should a person know when a bleeding cut is serious enough to require medical attention?
Here are some tips from Dr. Martin Brown, chairman of the department of emergency at Inova Alexandria Hospital in Virginia.
1. Laceration (裂口)
The medical term for a cut or tear in the skin is a laceration. 【小题1】 A long cut on a finger can likely be treated without a visit to a doctor if the wound is not very deep. However, if you have a short but deep laceration, you will need professional attention.
2. Fingertips cut off
Some injuries, like a fingertip that gets cut off, might even need surgery to repair. 【小题2】 More often, cutting down the bone is what is done because reattaching a fingertip is often not successful.
3. Bleeding
【小题3】 Small cuts usually produce what is known as venous (静脉的) bleeding. This means the blood flows steadily from the injury. The bleeding will often stop when pressure is put on the wound. In most cases holding direct pressure with a clean cloth for four to five minutes would do. But if a cut appears to be pumping blood out with some force, this may be a sign of arterial (动脉的) bleeding. 【小题4】
Finally, always keep this in mind: even a cut that does not require medical attention must be kept clean to prevent infection. Small cuts should be cleaned gently with clean water. 【小题5】 Then cover it with a clean, dry bandage.
| A.How a wound bleeds can be a sign of how serious it is. |
| B.That requires a specialist to either cut down the bone or reattach the fingertip. |
| C.This kind of injury should be treated by a medical professional as soon as possible. |
| D.The first signs of this disease include difficulty opening the mouth. |
F. With a cut finger, holding the hand above the heart can reduce the loss of blood.
G. The length is usually not as important as the depth.

In times of economic downturn, many people start to look for ways to reduce their household budget and save extra cash. Living a thrifty (节俭的) lifestyle does not have to mean doing nothing. 【小题1】 Here are some tips.
Track your spending for at least 2 weeks. You won’t really know how to live a thriftier lifestyle until you know where your money is going. Write down every time you spend money and take a look at it at the end of the month. 【小题2】
Search the Internet when you have to buy something. Because of the easy access to information, you can compare prices from more stores in less time.
【小题3】 Combining producers’ coupons (优惠券) with store discounts can lead to major savings.
Turn off the lights and other electronics in your home when you are not using them. 【小题4】 Leaving electronics on can use a tremendous amount of extra energy, costing you money.
【小题5】 When you do have to go out, look for available deals and discounts. If you are a frequent restaurant diner, consider purchasing a guide book for local restaurants, which will help you save money.
| A.Eat at home as often as possible. |
| B.You probably don’t really need 500 channels. |
| C.If you really can’t live without it, call the company. |
| D.Open a window and let in the natural light instead. |
F. So check your local stores as well as online providers to find the best price.
G. Instead, making small changes will allow you to save money and still enjoy yourself.
In the 60s, people asked about your astrological (about star) sign. In the 90s, they want to know your website. 【小题1】 Your website is an electronic meeting place for your family, friends and potentially, millions of people around the world. Best of all, you may not have to spend a cent. The web is filled with all kinds of free services and all it takes is some time and creativity.
【小题2】 Like the table of contents of a book or magazine, the home page is the front door. Your site can have one or more pages, depending on how you design it.
While web pages vary greatly in their design and content, most use a traditional magazine layout. At the top of the page is a banner(横幅). Next comes a greeting and a short description of the site. Pictures, text, and links to other websites follow.
【小题3】 Think about whom the site is for and what you want to say. Next, gather up the material that you want to put on the site.
While there are no rules you have to follow, there are a few things to keep in mind: 【小题4】 If you are too much at the beginning, you may never get the site off the ground. You can always add to your site.
Less is better. Most people don’t like to read a lot of long text online. 【小题5】 .
Smaller is better. Since it can take a long time to download large image files, keep the file sizes small.
Have the rights. Don’t put any material on your site unless you are sure you can do it legally. Always remember to get the permission from the writer first.
Now it’s time to roll up your sleeves and start building.
| A.Start simply. |
| B.Break it into small pieces. |
| C.Draw a rough layout on a sheet of paper. |
| D.Many websites are considered very interesting. |
F. Think of your home page as the starting point of your website.
G. These days, having a web address is almost as important as a street address.
Are you cooperative? Are you a good team member? If so, the future may hold more for you than you think.
【小题1】 That' s happening in those areas of business and data processing where one person and a computer can replace a team of workers.
But, elsewhere, teamwork is very much alive. High technology has led to a new type of teamwork in a number of fields, including advertising, scientific research, engineering design, architecture and ocean exploration.
Through computer networking, scientists, engineers and technicians at different locations —often thousands of miles apart —can work on the same project at once. 【小题2】
Examples— An engineering team can now design and try out a robot system ?a new manufacturing process or an entire factory —before it is built. 【小题3】 A medical team can simulate (模拟) a dangerous operation before performing it on a patient.
Of course, computer-assisted team effort doesn't end with investigation and simulation. 【小题4】 "CAD-CAM —computer-aided design and manufacture—is breaking down barriers between traditional design and manufacturing functions," explains Dr. Prakash Rao, an engineering manager at General Electric." Interdisciplinary (跨学科的) teams and engineers follow a product from concept to production. Everything is interconnected like a network. "
Sometimes, a computer-aided effort can extend beyond production. A team that produces robots may use them to explore space and ocean depths. 【小题5】
| A.They can exchange ideas, try out different designs and test their results. |
| B.In the future, teamwork will be highlighted by the introduction of new technology. |
| C.An architectural team can do the same with a building or a bridge. |
| D.It ends in the products which are extensions of the traditional design. |
F. High technology, some predicted, would make teamwork a thing of the past.
G. For high-technology teamwork, the future seems limitless.

Why Exercise Is Cool?
1. Exercise Strengthens Muscles
Did you ever do a push-up or swing across the monkey bars at the playground? 【小题1】 By using your muscles to do powerful things, you can make them stronger. For older teens and adults, this kind of workout can make muscles bigger, too.
2. 【小题2】
Can you touch your toes easily without yelling ouch? Most kids are pretty flexible, which means that they can bend and stretch their bodies without much trouble. Being flexible is having “full range of motion,” which means you can move your arms and legs freely without feeling tightness or pain.
3. Exercise Keeps the Balance
【小题3】 Your body needs a certain amount of calories every day just to function, breathe, walk around, and do all the basic stuff. 【小题4】 If you’re not very active, your body won’t need as many calories.
Whatever your calorie need is, if you eat enough to meet that need, your body weight will stay about the same. If you eat more calories than your body needs, it may be stored as extra fat.
4. Exercise Makes You Feel Good
It feels good to have a strong, flexible body that can do all the activities you enjoy—like running, jumping, and playing with your friends. It’s also fun to be good at something, like scoring a basket, hitting a home run, or perfecting a dive.
But you may not know that exercising can actually put you in a better mood. 【小题5】 It’s just another reason why exercise is cool!
| A.So you want to do some aerobic (有氧的) exercise right now? |
| B.Food gives your body fuel in the form of calories, which are a kind of energy. |
| C.When you exercise, your brain releases a chemical, which may make you feel happier. |
| D.Those are exercises that can build strength. |
F. Exercise Makes Your Heart Happy
G. But if you’re active, your body needs an extra measure of calories or energy.
Directions: Read the following text and choose the most suitable heading from A-F for each paragraph. There is one extra heading which you do not need.
| A. Tricks of dishonest advertisers |
| B. Types of advertisement readers |
| C. Customers’ opinions on advertisers |
| D. Functions of advertising |
| AB. Interactions between the advertisers and the customers |
| AC. Benefits one may get from reading honest advertisements. |
When you see a clever advertisement in a newspaper, do you say to yourself, “Ah, that’s good. I’d like to have one of these”? Or do you say, “What lies are they telling this time? It can’t be very good or they wouldn’t have to advertise it so cleverly”? Both of these people exist: the fist are optimists; the second pessimists and realists.
【小题2】
Advertisements can be extremely useful if they are honest: if, let us say, you have broken you pen and you want to buy another, the first thing to do is to look at as many advertisements for pens as you can find. That will help you to choose the model, color and price that suits you. Advertisements save a lot of time and trouble in a quick and simple way. If the advertisements are true and accurate, the customers will be satisfied and will probably buy from the same firm nest time and advise their friends and acquaintances to do the same.
【小题3】
Some advertisers hope to sell his goods quickly and to make a large profit on them. They know that no customers will buy from them a second time or recommend the products to their friends. Other advertisers make claims for their products which they know perfectly well to be incapable of verification, like advertising that a certain toothpaste contains a particular substance knowing that this substance is in fact neither beneficial or harmful to the teeth. Such advertisements do not tell downright lies, but their advertising is deliberately misleading.
【小题4】
If there was no advertising, fewer goods would be sold, so the cost of each article would be higher. The more you advertise, the more cheaply you can afford to sell your products. Advertising also encourages makers to improve their goods continually. One manufacturer of soap-power claims that his products does not harm housewives’ hands, and quotes the opinions of prominent doctors to prove this. All other soap-powder manufacturers are forced to make their products harmless too.
【小题5】
As advertisers become more and more expert at their work, they appeal to all the human emotions in the effort to increase sales: love of a bargain, fear of ill health, the desire to show off and many others. But more and more customers are also becoming suspicious of and resistant to high-powered advertising. This is producing a deliberately modest advertisement that is intended to disarm the customers’ suspicions by giving an impression of absolute sincerity, or even of deliberate understatement.
