The Supercomputer Network
1. Recently ten laboratories run by governments in different parts of the world have become linked. Their computers have been connected so they can "talk" to each other. This may not seem very dramatic news, but it is the beginning of a development that will increase the power of the Internet tremendously.
2. The Internet is an interconnected ( 互联 ) system of networks that connects computers round the world and facilitates the transmission and exchange of information. The way that you use the lnternet is by accessing this network. This depends on the power that your system allows you to use. The power of your computer is responsible for how fast you can download ( 下载 ) files, how much data you can store, etc. If your computer is old and slow, accessing the information can be very difficult.
3. The new development in information technology has been called "the grid" (网络技术), and it will be a network of computers that are linked together. The "grid" will work in a different way from the Internet, enabling you to get the power of the biggest computers in the world on your computer. Accessing the information will no longer depend on the power of your computer. The idea is that while you access
information, you will also have access to the power of the bigger computer stations.
4. One advantage of this revolutionary idea is that geographical location will become irrelevant. The "grid" will decide which are the best parts of a worldwide network to do the job you want. This means that you may be accessing a computer in Japan to solve a problem in Alaska.
5. The "grid" can be compared to having an efficient personal assistant. You can give your assistant a task and "he" will do it for you. The assistant will do the preliminary research, collect the data, compare them and decide on the best course of action by accessing any of the computer centres in the "grid" that happen to have the relevant information. All you have to do is assign the task, sit back and wait.
6. At present, possible applications of the "grid" in scientific research are being explored. While it has taken about fifteen years for Internet use to become widespread, experts believe that the "grid" could be up and running for private individuals far more quickly. Scientists working on "grid" projects are convinced that it will be as widely used as the web in the next ten years.
Paragraph 2__________
A．How does the "grid" work?
B．Power shared
C．Just make a request
D．Limitations of present Internet use
E．Distance is not a problem
F．A new era for the Internet

4、根据以下材料回答题：
Genetically Modified Foods
If you want to spark a heated debate at a dinner party, bring up the topic of genetically modified foods. For many people, the concept of genetically altered, high-tech crop production raises all kinds of environmental, healthy, safety and ethical questions. Particularly in countries with long grain traditions-and vocal green lobbies--the idea seems against nature.
In fact, genetically modified foods are already very much a part of out lives. A third of the corn and more than half the soybeans and cotton grown in the U.S. last year were the product of biotechnology, according to the Department of Agriculture. More than 65 million acres of genetically modified crops will be planted in the U.S. this year. The genetic genie ( 妖怪 ) is out of the bottle.
Yet there are clearly some very real issues that need to be resolved. Like any new product entering the food chain, genetically modified foods must be subjected to rigorous testing. In wealthy countries, the debate about biotech is tempered by the fact that we have a rich array of foods to choose from and a supply that far exceeds our needs. In developing countries desperate to feed fast-growing and underfed populations, the issue is simpler and much more urgent: Do the benefits of biotech outweigh the risks? The statistics on population growth and hunger are disturbing. Last year the world's population reached 6 billion. The U. N. estimates that nearly 800 million people around the world are undernourished. The effects are devastating. About 400 million women of child-bearing age are iron deficient, which means their babies are exposed to various birth defects. As many as 100 million children suffer from vitamin A deficiency, a leading cause of blindness.
How can biotech help? Biotechnologists have developed genetically modified rice that is fortified with beta-carotene-which the body converts into vitamin A and additional iron, and they are working on other kinds of nutritionally improved crops. Biotech can also improve farming productivity in places where food shortages are caused by crop damage attributable to pests, drought, poor soil and crop viruses, bacteria or fungi.

What's the passage mainly about?
A．The world's food problems.
B．The new advancement in biotech.
C．The characteristics of genetically modified foods.
D．How biotech can help solve the world's food problems.
