2、. One theory is that wolves howl to bend better together. Its almost as if howling together helps the pack stay together. Perhaps something similar to people feeling a sense of involvement with each other when singing a song together. But this theory may be wrong, explains Fred H. Harington, a profe
3、ssor who studies wolf behavior. Indeed, there have been tines when wolves have been seen one moment howling in a exhorts, and the next, quarreling anions each other. It appears that usually the lowest-tanking menthes of the pack may actually be “punished” for Joining in the chorus at times. So is ho
4、wling a way to strengthen a social bond or just a way to reconfirm status among its members? Why do wolves howl for sure?What is cleat, however, is that howling is often used among packmates to locate each other. Hunting grounds are distant and it happens that wolves may separate from one another at
5、 times. When this happens, howling appears to be an excellent means of gathering. Howling, interestingly, is a contagious behaviour. When one wolf starts to howl, very likely others will follow. This is often seen to occur in the morning, as if wolves were doing some sort of “roll call” where wolves

A person who eats such food can get an illness called food poisoning. Food p
10、oisoning is usually not serious, but some types are deadly, The symptoms of food poisoning usually begin within hours of eating the poisoned food. Fever is one of the most common symptoms.Certain microorganisms (微生物) cause most types of food poisoning. Bacteria and other microorganisms can poison eg
11、gs, meat, vegetables, and many other foods. After entering the body, these tiny living things release (释放) poisons that make people sick.Some chemicals can also cause food poisoning. They are often added to food while it is being grown, processed, or prepaid. For example, many farmers spray chemical
12、s on crops to kill weeds and insects. Some people may have a bad reaction to those chemicals when they eat the crops.Some plants and animals contain natural poisons that are harmful to people. These include certain kinds of seafood, grains, nuts, seeds, beans, and mushrooms.When people handle food p
13、roperly, the risk of food poisoning is very small Microorganisms multiply rapidly in dirty places and in warm temperatures. This means that people should never touch food with ditty hands or put food on unwashed surfaces. Food should be kept in a refrigerator to stop microorganisms from growing. Mea
14、t needs to be cooked thoroughly to kill any dangerous microorganisms. People should also wash food covered with chemicals before eating it. Finally, people should not eat raid mushrooms or other foods that grow in the wild. Some of these foods may contain natural materials that are poisonous to huma
15、ns. In addition, some types of fish can be poisonous.Most people recover from food poisoning after a few days of resting and drinking extra water. If people eat natural poisons, they must go to the hospital right away to have their stomachs emptied.51. Which of the following statements is NOT true?A
16、. Food when poisoned can make people sick.B. Food poisoning means death.C. Food poisoning comes in varieties.D. Food poisoning can be serious.52. We know from the passage that the symptoms of food poisoning .A. are always accompanied by a feverB. are too common to be notedC. can be noticed within ho
17、ursD. can be ignored53. Food poisoning can be caused by all the following EXCEPT .A. some chemicals B. low temperatures C. some tiny living things D. certain natural materials54. From Paragraph 5, we can learn thatA. mushrooms should not be eatenB. vegetables are safer than meat and seafoodC. natura
18、l poisons are more dangerous than chemicalsD. different types of food should be handled differently55. It can be inferred from the passage thatA. natural materials are safe in food processingB. chemicals are needed in food processingC. food poisoning can be kept under controlD. food poisoning is out

Brain-computer interface（BCI） technology could help people with disabilities send commands to machinesRecently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechni

28、 Could Help to Cure Brain InjuriesD（2009.安徽）Sometimes, the simplest ideas are the best. For example, to absorb heat from the sun to heat water, you need large, flat, black surfaces. One way to do that is to build those surfaces specially, on the roofs of buildings. But why go to all that trouble whe
29、n cities are full of black surfaces already, in the form of asphalt (柏油) roads? Ten years ago, this thought came into the mind of Arian de Bondt, a Dutch engineer. He finally persuaded his boss to follow it up. The result is that their building is now heated in winter and cooled in summer by a syste
30、m that relies on the surface of the road outside. The heat-collector is a system of connected water pipes. Most of them run from one side of the street to the other, just under the asphalt road. Some, however, dive deep into the ground. When the street surface gets hot in summer, water pumped throug
31、h the pipes picks up this heat and takes it underground through one of the diving pipes. At a depth of 100 metres lies a natural aquifer (蓄水层) into which several heat exchangers (交换器) have been built. The hot water from the street runs through these exchangers, warming the ground-water, before retur
32、ning to the surface through another pipe. The aquifer is thus used as a heat store.In winter, the working system is changed slightly. Water is pumped through the heat exchangers to pick up the heat stored during summer. This water goes into the building and is used to warm the place up. After perfor
33、ming that task, it is pumped under the asphalt and its remaining heat keeps the road free of snow and ice.64. Which of the following is true according to the first two paragraphs?A. Arian de Bondt got his idea from his boss. B. Large, flat, black surfaces need to be built in cities.C. The Dutch engi
34、neers system has been widely used.D. Heat can also be collected from asphalt roads.65. For what purpose are the diving pipes used?A. To absorb heat from the sun.B. To store heat for future use.C. To turn solar energy into heat energy. D. To carry heat down below the surface.66. From the last paragra
35、ph we can learn that _A. some pipes have to be re-arranged in winter B. the system can do more than warming up the building C. the exchangers will pick up heat from the street surface D. less heat may be collected in winter than in summer67. What is most likely to be discussed in the paragraph that
36、follows?A. What we shall do if the system goes wrong.B. What we shall do if there are no asphalt roads.C. How the system cools the building in summer.D. How the system collects heat in spring and autumn.改错题 After a day of work and play，the body needs to have a rest. Sleep is necessary for good healt
37、hy. During this time，the body recovers from the activities of the day. The rest what you get while sleeping enables your body to prepare it for the next day. There are four levels of sleep. Each is a little deeper than the one before. With you sleep，your muscles relax Your heart jumps more slowly，an
38、d your brain slows down. After you reach the fourth level，your body shifts back or forth from one level of sleep to the other. If you have trouble fall asleep，some people suggest breathing slowly and deeply. And other people believe that drink warm milk helps make you sleepy. There is also a old suggestion that counting sheep put you sleep.
