    10．An experimental treatment that causes AIDS patients to develop a dangerously high fever has shown promise as a way of prolonging and improving the patients'life．Called the Biologic-HT System，the new treatment lets doctors extract the blood of a patient and heat it before circulating it back into the body．The heated blood causes the patient's body temperature to rise above 42 degrees Celsius．In people with AIDS，that increase in temperature kills some heat-sensitive HIV，the virus，most doctors say，causes AIDS．
    Heating the blood of AIDS patients has been tried before，say doctors．But during previous attempts，the treatment induced deadly chemical changes in the blood．The Biologic-HT System prevents those changes from happening，allowing the heat to kill viruses with few ill side effects．
    The new heat treatment cannot be considered a cure for Aids，says president of the company that makes the system．He says the treatment doesn't kill all traces of the virus．However，it kills enough virus particles to give a patient's immune system a reprieve in its deadly duel with HIV．
    Tests of the Biologic-HT treatment began on 36 patients earlier this year．The treatment takes about four hours，and the patient normally feels well enough to leave the hospital or clinic the following morning．
    So far，the patients who have had the treatment say they feel better and have developed no new opportunistic infections-disease that strike people with damaged immune systems．The patients also have experienced about a 50 percent increase in the number of T cells in their bodies．T cells are key disease-fighting cells of the immune system and the main target of HIV．
    36．This passage is mainly concerned withA．
    A．a way for treating AIDS              
    B．a heat-sensitive virus
    C．the immune system of the human body
    D．the function of high temperature
    37．The blood of the patientD．
    A．is heated with a single injection
    B．is heated by being circulated at a higher rate
    C．is taken out from the body and then circulated through a heating system．
    D．is taken out from the body，heated outside and then put back into the body．
    38．The previous attempts to use high temperature for treating AIDS failed because theyA．
    A．caused chemical changes     B．could not kill HIV effectively
    C．resulted in deaths          D．killed both HIV and healthy cells
    39．According to the passage，the new treatment．B
    A．can kill all the HIV viruses
    B．cannot eliminate the viruses completely
    C．can double the number of disease-fighting cells
    D．can reconstruct the patient's immune system．
    40．The result of the experiment seems to beC．
    A．disappointing   B．incomplete   C．successful     D．surprising．

    分析 本文讲述了一种新型的治疗艾滋病的方法，把病人的血液抽出来，加热以后再输回病人的体内，通过这种方式来治疗艾滋病．

    解答 36．A．主旨大意题．根据文章主题段第一段第一行Anexperimental treatment that causes AIDS patients to develop a dangerously highfever has shown promise as a way of prolonging and improving the patients'life．说明本文是关于治疗艾滋病的一种新的治疗方法，故A正确．
    37．D．细节理解题．根据第一段3，4行the new treatment lets doctors extract the blood of apatient and heat it before circulating it back into the body．说明是把病人的血液先抽出来，然后进行加热，最后在输回病人体内，故D正确．
    38．A．细节理解题．根据第二段1，2行Heating the blood of AIDS patients has been triedbefore，say doctors．But during previous attempts，the treatment induced deadlychemical changes in the blood．说明在先前的实验中，病人的血液在加热的过程中出现了问题，故A正确．
    39．B．细节理解题．根据第3段2，3，4行He says the treatment doesn'tkill all traces of the virus．However，it kills enough virus particles to givea patient's immune system a reprieve in its deadly duel with HIV说明这种方法并不能完全第杀死艾滋病的病菌，故B正确．
    40．C．推理判断题．根据文章最后一段So far，thepatients who have had the treatment say they feel better and have developed nonew opportunistic infections-disease that strike people with damaged immunesystems．The patients also have experienced about a 50 percent increase in thenumber of T cells in their bodies．T cells are key disease-fighting cells ofthe immune system and the main target of HIV．说明到目前为止这个治疗的方法是成功的，故C正确．

    点评 考察学生的细节理解和推理判断能力，做细节理解题时一定要找到文章中的原句，和题干进行比较，再做出正确的选择．在做推理判断题不要以个人的主观想象代替文章的事实，要根据文章事实进行合乎逻辑的推理判断．

    1．The right name is important in the business world．All you have to do is think of the names for some of the products you buy every day and you'll agree that the name and the product are connected in everyone's mind．
    In many countries，successful trade or brand names are protected by law．This is so that other companies cannot make a product that looks like another．People might think that they were buying one product and，in fact，be buying something different．Businesses register a company or a product name with the government．In fact，more than 1，000 product and company names are registered every hour．Many companies spend a lot of money to find the right name for their products．A good example of this is in the car industry．Some successful names for cars have powerful associations．The Ford Mustang and the Jaguar are only two examples of choosing the names of animals that are fast and strong．
    When a U．S．company decides to sell its product in another country，it has to make sure that the product name translates properly．When Coca-Cola introduced its soft drink to China，it looked for the right name．It wanted a name that would do two things．One was to present its image in Chinese and the second was to be close to its first brand name-Coke．It took some efforts before finding the right word-which sounds similar and translates as"happiness in the mouth"．Asian company names are not new to the United States．The brand names of Samsung and Sony have been successful．Finding the right brand name is a big business．Asian companies that sell to foreign markets pay to find a name that will connect with its customers．There are even naming companies that specialize in inventing product names．These companies can charge up to $ 100，000 a word for their creations．But it's worth it．Successful companies know how important the right brand names are for their development．
    59．Why are trade names protected by law in many countries？D
    A．To make companies pay for naming service．
    B．To help people choose the best products．
    C．To present good images of the products．
    D．To prevent products from being copied．
    60．What can we learn from the passage？B
    A．Many companies care about the cost of finding the right names．
    B．Creative trade names can help companies to have a larger sale．
    C．The government often does business with naming companies．
    D．It is considered necessary for cars to be named after animals．
    61．What's the best title for the passage？A
    A．The Business of Names

    18．More and more parents are worrying about their daughters who have become overweight．Girls who think they aren't popular at school are at higher risk for weight gain，according to a new study．It's long been known that being overweight can lead to social exclusion （排斥） for teens，but researchers at Harvard University discovered：whether a student's opinions of her social position played a role in her weight．
    To find out，the researchers measured the body weight of nearly 4，500 girls aged 12 to 18．
    Two years later，the researchers found，all of the girls had gained weight-no surprise，since they were all growing．But girls who thought they were less popular at school were at a 70 percent higher risk of gaining extra weight．
    The researchers considered something else besides the collected information，including whether a child was overweight at the start of the study，family income，a mother's weight，diet，television viewing habits and some other things that can affect childhood weight gain．But the opinions of girl's popularity are more likely to affect he girls'weight．
    Experts suggested that parents concerned about a girl's weight should look not only at eating habits but also at their child's social network，encouraging relationships with friends and joining in group activities．Meanwhile schools should also organize more programs to help girls build social skills，they added．
    64．Which kind of girls is less likely to gain extra weight？B
    A．Those who like watching TV for a long time per day．
    B．Those whose parents show no sign of being overweight．
    C．Those who are self-centered and not optimistic．
    D．Those who enjoy meals rich in high oil and fat．
    65．What can parents do in controlling their teenage girls'weight？D
    A．They encourage their kids to study hard．
    B．They ask their daughters eat as they please
    C．They record the body weight measurements of their own kids．
    D．They make their kids communicate more with others．
    66．It can be concluded from this passage thatA．
    A．A rising number of teenager girls are becoming overweight
    B．Some schools have already organized various activities for teenager girls．
    C．Girls aged 17 are certainly heavier than those aged 14．
    D．The researchers reached the final discovery only by studying the collected information．
    67．How is the text organized？B
    A．topic-argument-description-conclusion
    B．opinion-supporting examples-conclusion-advice
    C．opinion-supporting examples-solution-advice
    D．topic-argument-conclusion-solution．

    5．Youngsters who have no regular bedtime or who go to bed later than 21：00 have lower scores for reading and maths．Lack of sleep may influence how well the brain learns new information．
    The findings on sleep patterns and brain power come from a UK study of more than 11，000 seven-year-olds．
    Theygathered information on the children at the ages of three，five and seven to find out how well they were doing with their learning and whether that might be related to their sleeping habits．
    Establishing （制定） a good bedtime routine early in childhood is important．Irregular bedtimes were most common at the age of three，when around one in five of the children went to bed at varying times．By the age of seven，more than half the children had a regular bedtime of between 19：30 and 20：30．
    Children with irregular bedtimes tended to be less successful than their playmates in terms of test scores for reading，maths and spatial awareness（空间想象）．The influence was more obvious throughout early childhood in girls than in boys and appeared to be increasing．
    The researchers said it was possible that irregular bedtimes were a reflection of chaotic （无秩序的） family settings and they had an influence on cognitive （认知的） performance in children．The children with late and irregular bedtimes came from more socially disadvantaged backgrounds and were less likely to be read to each night and，generally，watched more TV．After controlling for such factors，the link between poorer mental performance and irregular bedtimes remained．
    67．The text mainly deals with the relation between children'sD．
    A．reading abilities and their sleeping habits
    B．mental development and their sleeping habits
    C．behaviour and their studying habits
    D．performance in learning and their sleeping habits
    68．The underlined word"They"in the third paragraph refers to"B"
    A．the findings                     
    B．the researchers
    C．the seven-year-olds             
    D．the sleep patterns             
    69．Which of the following is TRUE according to the text？C
    A．About one third of the three-year-olds go to bed at irregular bedtimes．
    B．Irregular bedtimes were most common before the children were three months old．
    C．More than half the children didn't have a regular bedtime until they were seven years old．
    D．Teachers should help their kids establish a good bedtime routine early in childhood．
    70．We can know from the text thatD．
    A．boys with irregular bedtimes do worse in reading than their playmates
    B．girls with regular bedtimes perform better in learning than boys
    C．girls with irregular bedtimes do worse in reading than boys
    D．the gap between girls with and without regular bedtimes is larger than that between boys．

    15．Pulling luggage through the airport can be a pain，as any frequent traveler will tell you．A new suitcase called only"Hop"is looking to change all of that，though，using signals from your cell phone to go hands-free．
    According to Hop's official website，the suitcase uses three sensors （感应器） to identify the Bluetooth signal from your phone and pick you out of a crowd．Once it's done that，a microprocessor not only figures out Hop's position as it relates to your phone，but controls the two caterpillar tracks （履带） in the bottom of the unit to get it moving．Hop follows behind the user at a constant distance，so you don't have to worry about it"stepping"on your heels，so to speak．If it loses the signal it's following，your phone will vibrate，letting you know that your poor suitcase is lost and alone in a sea of strange people．
    We can see Hop in action in the video below，and we have to say that it looks like a great little device．There's just one problem：it looks as if you'll have to walk at a relatively slow pace to keep the suitcase from losing the signal．Since a walk through an airport is rarely a leisurely experience，that could potentially cause troubles．Also，don't expect TSA agents to just smile and wave as you walk through security with a remote-controlled suitcase tailing you．
    Still，the idea behind Hop is really cool，and we're willing to believe that there are some frequent flyers who would like to put down some money for it right this instant．However，this is just a model at the moment，so don't expect it to be available for sale anytime soon （if it ever is，for that matter）．Would you purchase one of these if Hop ever became available commercially？
    66．What is"to go hands-free"？A
    A．The new suitcase
    B．Your cell phone．
    C．Signals from your cell phone
    D．Frequent travelers．
    67．Which paragraph tells about how Hop works？B
    A．Paragraph One
    B．Paragraph Two
    C．Paragraph Three
    D．Paragraph Four．
    68．The article is probably taken fromB．
    A．Hop's official website                   
    B．a website of worldwide news
    C．a Western newspaper                   
    D．a Chinese newspaper
    69．According to the article，Hop may run into trouble becauseC．
    A．your cell phone fails to tell you Hop is lost 
    B．its caterpillar tracks aren't powerful enough
    C．you usually walk too fast for Hop to follow   
    D．TSA agents won't be patient enough
    70．What does the writer think of the invention？D
    A．Hop will be in production soon
    B．Hop is sure to be popular someday．
    C．It's silly to have thought of that
    D．Hop might never go on sale．

    2．A blue hole is a flooded sea cave with a hole that opens up at the land's surface．These cave systems form in carbonate rock，often on islands．Some blue holes have very special rock formations and water chemistry．Far below sea level，they contain some of the harshest environments on Earth，with no oxygen and no light．Yet these areas are filled with life forms that have adapted to the extreme conditions．
    Information gathered from these blue holes is helping scientists to increase their understanding of biology，archaeology and geology．But exploring these blue hole environments brings danger as well as discovery．
    Blue holes get their name from the color some have when seen from the air．The color is usually a reflection of the sky on the water．But not all of these cave systems have blue surfaces．Some contain dark or muddy water．
    Blue holes are the result of erosion in which water breaks down rock．Rain falling thousands of years ago contained chemicals which slowly wore away at the limestone landmass．These holes were later filled with sea water as the sea level changed．The rising and falling of sea levels and the mixture of salt and fresh water further wore away at these cave formations．Blue holes are vertical caves．But they can also have horizontal cave formations that may be hundreds of meters long．
    These flooded cave systems can be found in the ocean，or they can be found inland．Ocean caves are affected by tides，so they always have water movement．But blue holes on land are very still．They have several layers of water，chemicals，and bacteria．The top layer of fresh water comes from rainfall．This layer acts like a cap on top of the layered mixture，and keeps out oxygen from the atmosphere．The fresh water floats on a denser layer of saltwater．Underneath this is a layer of poisonous hydrogen sulfide，produced by bacteria living in the water．Underneath this layer is anoxic seawater--water that does not contain any oxygen．
    Underwater caves are probably one of the least explored ecosystems on the planet．One reason blue holes have not been fully explored is that they can be extremely dangerous．There are many safety rules that divers must follow to help ensure their survival．
    First，divers must have training and experience to swim in these caves．Those who explore a cave for the first time must establish a thin rope called a guideline．This line helps them to safely enter and bring more than one set of breathing equipment in case one device fails．Meanwhile，they must pay careful attention to their air supply．The rule is to use a third of their air to enter the cave，a third to exit，and a third for emergencies．
        For most explorers，though，the possibility of discovery in these cave environments makes the experience worth the risk．You can jump into what looks like an insignificant little hole in the ground，and come out with information that's of value to many different disciplines，Scientists are interested in these caves because oxygen-free conditions there are similar to those on Earth long ago，before oxygen existed on our planet．，as well as similar to space．
    50．According to the Passage，blue holesB．
    A．are now a popular choice for tourists
    B．are flooded caves found mostly on islands
    C．have appeared as rocks pile up year by year
    D．can give off bright blue light deep in the caves
    51．It can be inferred front the passage thatD．
    A．quantities of advanced life forms exist in blue boles
    B．blue holes are not fully explored due to their low value
    C．blue holes are vertical caves because of strong currents
    D．the chemicals in the rain lead to the formation of blue caves
    52．The fifth paragraph mainly talks aboutA．
    A．two different types of blue holes    
    B．how a blue hole comes into being
    C．why scientists are interested in blue holes       
    D．rules for divers exploring blue holes
    53．When exploring blue holes，divers mustD．
    A．have a thin rope as a guideline anytime           
    B．wear glasses in case of bright blue light
    C．swim as quickly as possible to save time          
    D．learn to make good use of their air supply
    54．The exploration of blue holes can help usB．
    A．discover moue energy resources  
    B．understand the origin of life on Farth
    C．learn about the movements of seawater
    D．get ready for the exploration of the ocean．
