important means of communication each other There are different explants of a wolf s howl and it appears that there may be more to discover One theory is that wolves howl to bend better together It s 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 professor 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 howling 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 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 all howl together to howl very likely others will follow This is often seen to occur in the morning as if wolves were doing w some sort of roll call where wolves all howl together to report their presence 55 What the possible similarity between wolves how humans ting in chorus A The act of calling each other B The sense of accomplishment C The act of hunting for something D The sense of belonging to a group 56 Why does Harrington think the social bond theory may be wrong A Wolves separate from each other after howling B Wolves tend to protect their hunting grounds 2 C Wolves sometimes have quarrels after howling together D Wolves of low rank are encouraged to join in the chorus 57 Reseatchers are sure that wolves often howl to A show their ranks B find their companions C report the missing onesD express their loneliness 58 Howling is a contagious behaviour in the last paragraph means A howling is a signal for huntingB howling is a way of communication C howling often occurs in the morningD howling spreads from one to another B B 2010 2010 广东 广东 Food sometimes gets poisoned with harmful things A person who eats such food can get an illness called food poisoning Food poisoning 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 eggs 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 chemicals 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 properly 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 Meat 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 humans In addition some types of fish can be poisonous Most people recover from food poisoning after a few days of 3 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 NOTNOT true A 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 noted C can be noticed within hoursD can be ignored 53 Food poisoning can be caused by all the following EXCEPT A some chemicals B low temperatures C some tiny living things D certain natural materials 54 From Paragraph 5 we can learn that A mushrooms should not be eatenB vegetables are safer than meat and seafood C natural poisons are more dangerous than chemicals D different types of food should be handled differently 55 It can be inferred from the passage that A natural materials are safe in food processingB chemicals are needed in food processing C food poisoning can be kept under controlD food poisoning is out of control C C 2011 2011 山东 山东 Since the 1970s scientists have been searching for ways to link the brain with computers Brain computer interface BCI technology could help people with disabilities send commands to machines Recently two researchers Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne Switzerland demonstrated 展示 a small robotic wheelchair directed by a person s thoughts In the laboratory Tavella operated the wheelchair just by thinking about moving his left or right band He could even talk as he watched the vehicle and guided it with his thoughts Our brain has billions of nerve cells These send signals through the spinal cord 脊髓 to the muscles to give us the ability to move But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles Tavella says Our system allows disabled people to communicate with external world and also to control devices The researchers designed a special cap for the user This head cover picks up the signals from the scalp 头皮 and sends them to a 4 computer The computer interprets the signals and commands the motorized wheelchair The wheelchair also has two cameras that identify objects in its path They help the computer react to commands from the brain Prof Millan the team leader says scientists keep improving the computer software that interprets brain signals and turns them into simple commands The practical possibilities that BCI technology offers to disabled people can be grouped in two categories communication and controlling devices One example is this wheelchair He says his team has set two goals One is testing with real patients so as to prove that this is a technology they can benefit from And the other is to guarantee that they can use the technology over long periods of time 71 BCI is a technology that can A help to update computer systems B link the human brain with computers C help the disabled to recover D control a person s thoughts 72 How did Tavella operate the wheelchair in the laboratory A By controlling his muscles B By talking to the machine C By moving his hand D By using his mind 73 Which of the following shows the path of the signals described in Paragraph 5 A scalp computer cap wheelchairB computer cap scalp wheelchair C scalp cap computer wheelchairD cap computer scalp wheelchair 74 The team will test with real patients to A make profits from them B prove the technology useful to them C make them live longer D learn about their physical condition 75 Which of the following would be the best title for the text A Switzerland the BCI Research Center B New Findings About How the Human Brain Works C BCI Could Mean More Freedom for the Disabled D Robotic Vehicles Could Help to Cure Brain Injuries D D 2009 2009 安徽 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 5 of buildings But why go to all that trouble when 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 system 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 through 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 returning 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 performing 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 engineer s 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 paragraph we can learn that A some pipes have to be re arranged in winter B the system can do m
