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 Intermit 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” （网格技术），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 gave 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 centers in the “grid” that happen to have the relevant information. Ail 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 us and running for private individuals far more quickly. Scientists working “grid” projects are convinced that it will be as widely used as the web in the next ten years.

下面有3篇短文，每篇短文后有5道题。请依照短文内容，为每题拟定1个最佳选项。 第一篇
Sunspots
It's not surprising that sunspots（太阳黑子）were observed by ancient astronomers（天文学家）. The largest soupspoon the sun can be seen without a telescope. It was not until the invention of the telescope（望远镜）in the early 17th century，however，that systematic studies of sunspots could be undertaken. The great astronomer Galileo was among the first to make telescopic observations of sunspots.
Sunspots are regions of extremely strong magnetic fields（磁场）found on the sun’s surface. A sunspot has a dark central core known as the umbra. The umbra is surrounded by a dark ring called the penumbra，where the magnetic field spreads outward. Sunspots appear dark because they are giving off less radiation. They are cooler than the rest of the sun’s surface. Sunspots are frequently observed in pairs of in paired groups. The members of a spot pair are identified as the leading spot and the following spot. They are identified by their position in the pair in terms of the direction in Which the sun rotates（旋转）. The number of sunspots at any one time varies. A large spot group may consist of as many as 10 groups and 300 spots across the sun. The number of spots changes in a fairly regular pattern called the sunspot cycle. The largest number occurs about every 11 years. At sunspot minim L{m，there are at most just a few small spots. The average lifetime of an individual spot group is roughly one solar rotation，which is about 25 days. The most persistent large slops，however can survive for two to three months.

Where Have All the Bees Gone?
Scientists who study insects have a real mystery on their hands. All across the country，honeybees are leaving their hives（蜂巢）and never returning. Researchers call this phenomenon colony-collapse（群体瘫痪）disorder. It is reposed that 25 to 40 percent of the honeybees in the US have vanished from their hives since last fall. So far，no one can explain why.
Colony collapse is a serious concern because bees play an important role in the production of about one-third of the foods we eat. As they feed，honeybees spread pollen（花粉）from flower to flower. Without this process，a plant can’t produce seeds or fruits.
Now，a group of scientists and beekeepers have teamed up to try to figure out what’s causing the alarming collapse of so many colonies. They hope to find out what’s contributing to the decline and to prevent bee disappearance in the future.
It could be that disease is causing the disappearance of the bees. To explore that possibility，Jay Evans，a researcher at the United States Department of
