6、e Need to Remember/BSome people say they have no memory at all: “I just cant remember a thing!“ But of course we all have a memory. Our memory tells us who we are. Our memory helps us to make use In the present of what we have learnt in the past.in fact we have different types of memory. For example

7、, our visual memory helps us recall facts and places. Some people have such a strong visual memory, they can remember exactly what they have seen, for example, pages of a book, as a complete picture.Our verbal (言语的) memory helps us remember words and figures we may have heard but not seen or written

8、: items of a shopping list, a chemical formula, dates, or a recipe.With our emotional (情感的) memory, we recall situations or places where we had strong feelings, perhaps of happiness or unhappiness. We also have special memories for smell, taste, touch and sound, and for performing physical movements

9、.We have two ways of storing any of these memories. Our short-term memory stores items for up to thirty seconds enough to remember a telephone number while we dial. Our long-term memory, on the other hand, may store items for a lifetime. Older people in fact have a much better long-term memory than

10、short-term. They may forget what they have done only a few hours ago, but have the clearest remembrance (记忆) of when they were very young.Psychologists tell us that we only remember a few facts about our past, and that we invent the rest. It is as though we remember only the outline of a story. We t

Their computers have been connected so they can “talk“ to each other. This may no

15、t 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

16、 you use the Internet 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 v

17、ery 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 comp

18、uter. 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.

19、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“ wil

20、l 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 p

The largest sunspots on the sun can be seen without a telescope. It was not until the invention of the telescope (望远镜) in the

26、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 suns surface. A sunspot has a dark Central cor

27、e 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 suns surface.Sunspots are frequently observed in pairs or in paired groups

28、. 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

29、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 minimum, there are at most just a few small spots.The average lifetime of an individual spot group is roughly one solar rotation, whi

30、ch is about 25 days. The most persistent large spots, however, can survive for two to three months.（分数：15.00）(1).Careful observations and systematic studies of sunspots（分数：3.00）A.were made by ancient astronomersB.started in the early 17th centuryC.were made by Galileo onlyD.could be made without a t

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 reported tha

34、t 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) f

35、rom flower to flower. Without this process, a plant cant produce seeds or fruits.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 disappear

36、ance 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 Agriculture (USDA) Bee Research Laboratory, examines bees taken from colonies that are collapsing. “We know what a healthy bee

37、 should look like on the inside, and we can look for physical signs of disease,“ 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) is damaging the bees digestive org

38、ans. Their immune (免疫的) systems may not be working as they should. Moreover, they have high 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 Fl

39、orida Department of Agriculture. Some studies, he says, suggest that a certain type of insecticide (杀虫剂) affects the honeybees nervous 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 contribut

40、ing to colony collapse, bees genes could explain why some colonies have collapsed and others 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

41、diversity in colony collapse, but its a promising theory, says Evans.（分数：15.00）(1).What is the mystery that researchers find hard to explain?（分数：3.00）A.Honeybees are flying all across the countryB.Half of the honeybees in the US have diedC.Honeybees are leaving their hives and do not returnD.Honeybe

45、BBA Tale of Scottish Rural Life/BLewis Grassic Gibbons Sunset Song (1932) was voted“ the best Scottish novel of all time“ by Scotlands reading public in 2005. Once considered shocking for its frank description of aspects of the lives of Scotlands poor rural farmers, it has been adapted for stage, fi

46、lm, TV and radio in recent decades.The novel is set on the fictional estate of Kinraddie, in the farming country of the Scottish northwest in the years up to and beyond World War t. At its heart is the story of Chris, who is both part of the community and a little outside it.Grassic Gibbon gives us

47、the most detailed and intimate account of the life of his heroine (女主人公). We watch her grow through a childhood dominated by, her cruel but hard- working father; experience tragedy (her mothers suicide and murder of her twin children) and learn about her feelings as she grows into a woman. We see he

48、r marry, lose her husband, then marry again. Chris has seemed so convincing a figure to some female readers that they cannot believe that she is the creation of a man.But it would be misleading to suggest that this book is just about Chris. It is truly a novel of a place and its people. Its opening section tells of Kinraddies long history, in a language that imitates the places changing patterns of speech and writing.The story itself is amazingly full of characters and incidents. It is told from Chris point of view but also from that of the gossiping community, a community where everybod
