Companies in the US are developing the technology needed to clone chickens on a massive scale. Once a chicken with desirabl
2、e traits has been bred or genetically engineered, tens of thousands of eggs, which will hatch into identical copies, could roll off the production lines every hour. Billions of clones could be produced each year to supply chicken farms with birds that all grow at the same rate, have the same amount
3、of meat and taste the same. This, at least, is the vision of the USs National Institute of Science and Technology, which has given Origen Therapeutics of Burlingame, California, and Embrex of North Carolina $4.7 million to help fund research. The prospect has alarmed animal welfare groups, who fear
4、it could increase the suffering of farm birds. Thats unlikely to put off the poultry industry, however, which wants disease-resistant birds that grow faster on less food. Producers would like the same meat quantity but to use reduced inputs to get there, says Mike Fitzgerald of Origen. To meet this
5、demand, Origen aims to create an animal that is effectively a clone, he says. Normal cloning doesnt work in birds because eggs cant be removed and implanted. Instead, the company is trying to bulk-grow embryonic stem cells taken from fertilized eggs as soon as theyre laid, The trick is to culture th
6、e cells without them starting to distinguish, so they remain pluripotent, says Fitzgerald. Using a long-established technique, these donor cells will then be injected into the embryo of a freshly laid, fertilized recipient egg, forming a chick that is. a chimera. Strictly speaking a chimera isnt a c
7、lone, because it contains cells from both donor and recipient. But Fitzgerald says it will be enough if, say, 95 percent of a chickens body develops from donor cells. In the poultry world, it doesnt matter if its not 100 percent, he says. Another challenge for Origen is to scale up production. To do
8、 this, it has teamed up with Embrex, which produces machines that can inject vaccines into up to 50,000 eggs an hour. Embrex is now trying to modify the machines to locate the embryo and inject the cells into precisely the right spot without killing it. In future, Origen imagines freezing stem cells
9、 from different strains of chicken. If orders come in for a particular strain, millions of eggs could be produced in months or even weeks. At present, maintaining all the varieties the market might call for is too expensive for breeders, and it takes years to breed enough chickens to produce the bil

11、dentical eggs can be hatched on the production lines. 2.B第二篇/BBThe Only Way Is Up/B Think of a modem city and the first image that come to mind is the skyline. It is full of great buildings, pointing like fingers to heaven. It is true that some cities dont permit buildings to go above a certain heig
12、ht. But these are cities concerned with the past. The first thing any city does when it wants to tell the world that it has arrived is to build skyscrapers. When people gather together in cities, they create a demand for land. Since cities are places where money is made, that demand can be met. And
13、the best way to make money out of city land is to put as many people as possible in a space that covers the smallest amount of ground. That means building upwards. The technology existed to do this as early as the 19th century. But the height of buildings was limited by one important factor. They ha
14、d to be small enough for people on the top floors to climb stairs. People could not be expected to climb a mountain at the end of their journey to work, or home. Elisha Otis, a US inventor, was the man who brought us the lift - or elevator, as he preferred to call it. However, most of the technology
15、 is very old. Lifts work using the same pulley system the Egyptians used to create the Pyramids. What Otis did was attach the system to a steam engine and develop the elevator brake, which stops the lift falling if the cords that hold it up are broken. It was this that did the most to gain public co
16、nfidence in the new invention, In fact, he spent a number of years exhibiting lifts at fairgrounds, giving people the chance to try them out before selling the idea to architects and builders. A lift would not be a very good theme park attraction now. Going in a lift is such an everyday thing that i
17、t would just be boring. Yet psychologists and others who study human behavior fund lifts fascinating. The reason is simple. Scientists have always studied animals in zoos. The nearest they can get to that with humans is in observing them in lifts. It breaks all the usual conventions about the bubble
18、 of personal space we carry around with us and you just cant choose to move away, says workplace psychologist, Gary Fitzgibbon. Being trapped in this setting can create different types of tensions, he says. Some people are scared of them. Others use them as an opportunity to get close to the boss. S

21、ny things about language are a mystery, and many will always remain so. But some things we do know. First, we know that all human beings have a language of some sort. There is no race of men anywhere on earth so backward that it has no language, no set of speech sounds by which the people communicat
22、e with one another. Furthermore, in historical times, there has never been a race of men without a language. Second, there is no such thing as a primitive language. There are many people whose cultures are undeveloped, who are, as we say, uncivilized, but the languages they speak are not primitive.
23、In all known languages we can see complexities that must have been tens of thousands of years in developing. This has not always been well understood; indeed, the direct contrary has often been stated. Popular ideas of the language of the American Indians will illustrate. Many people have supposed t
