6、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. 2The Int

7、ernet 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 compu

8、ter 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. 3The new development in information technology has been called “the grid” （网格技术）, and it will be a network of computers that

9、 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

10、 also have access to the power of the bigger computer stations. 4One 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 comput

The assistant will do the preliminary research, collect the data, compare them and decide on the best course of action by a

16、, 每篇短文后有5道题。请根据短文内容, 为每题确定1个最佳选项。第一篇SunspotsIts 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

17、 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 suns surface. A sunspot has a dark central core known as the umbra. The umbra is surrounded by a dar

18、k 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 suns surface. Sunspots are frequently observed in pairs of in paired groups. The members of a spot pair are identified as the le

19、ading 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

20、 in a fairly regular pattern called the sunspot cycle. The largest number occurs about every 11 years. At sunspot minim Lm, 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 slop

21、s, however can survive for two to three months. 31. Careful observations and systematic studies of sunspotsA. were made by ancient astronomers. B. started in the early 17th century.C. were made by Galileo only. D. could be made without a telescope.32. Sunspots are cooler than the rest of the suns su

22、rface becauseA. they produce less energy. B. they are buried in the sun.C. they are far away from magnetic fields. D. they are close to magnetic fields.33 The leading spot and the following spot are the names ofA. two large sunspots. B. a large spot and a small spot。C. the two spots in a spot pair.

23、D. the central core and the ring around it.34. Infiniteness sunspot activity had occurred in 1857, the next one would have been inA. 1858. B. 1862. C. 1865 D. 186835 In the last paragraph the word persistent meansA. important. B. effective. C. enduring. D. visible.第二篇Where Have All the Bees Gone?Sci

24、entists 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 hive

25、s 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 cant produce seeds or fr

26、uits. Now, a group of scientists and beekeepers have teamed up to try to figure out whats causing the alarming collapse of so many colonies. They hope to find out whats contributing to the decline and to prevent bee disappearance in the future. It could be that disease is causing the disappearance o

27、f the bees. To explore that possibility, Jay Evans, a researcher at the United States Department of Agriculture（SDA）Bee Research Laboratory, examines bees taken from colonies that are collapsing. “We know what a healthy bee should look like on the inside and we can look for physical signs of disease

28、.” he says. And bees from collapsing colonies dont look very healthy. “Their stomachs are worn down compared to the stomachs of healthy bees,” Evans says. It may be that a parasite（寄生虫）making the bees digestive organs. Their immune（免疫的）systems may not be working as they should. Moreover, they have h

29、igh levels of bacteria inside their bodies.Another cause of colony-collapse disorder may be certain chemicals that farmers apply to kill unwanted insects on crops, says Jerry Hayes, chief bee inspector for the Florida Department of Agriculture. Some studies, he says, suggest that a certain type of i

30、nsecticide（杀虫剂）affects the honeybees newels system and memory. “It seems like honeybees are going out and getting confused about where to go and what to do,” he says. If it turns out that a disease is contributing to colony collapse, bees genes could explain why some colonies have collapsed and othe

31、rs have not. In any group of bees there are many different kinds of genes. The more different genes a group has, the higher the groups genetic diversity. So far scientists havent determined the role of genetic diversity in colony collapse, but its a promising theory, says Evans. 36. What is the mystery that researchers find hard to explain? A. Honeybees are flying all across the country. B. Half o
