    A device that stops drivers from falling asleep at the wheel is about to undergo(接受) testing at Department of Transport laboratories and could go on sale within 12 months.
    The system, called driver Alert, aims to reduce deadly road accidents by 20%--40% that are caused by tiredness. Airline pilots can also use it to reduce the 30% of all pilot-error accidents that are related to fatigue（疲劳）.
    Driver Alert is based on a computerized wristband. The device, worn by drivers or pilots gives out a sound about every four minutes during a car journey. After each sound the driver must respond by squeezing the steering wheel(方向盘). A sensor in the wristband detects this pressing action and measures the time between the sound and the driver’s response.
    Tiredness is directly related to a driver’s response time. Usually, a watchful driver would take about 400 milliseconds to respond, but once that falls to more than 500 milliseconds, it suggests that the driver is getting sleepy.
    In such cases the device gives out more regular and louder sounds, showing that the driver should open a window or stop for a rest. If the driver’s response continues to slow down, the sounds become more frequent until a nonstop alarm warns that the driver must stop as soon as possible.
    The device has been delivered to the department’s laboratories for testing. If these tests, scheduled for six months’ time, are successful, the makers will bring the product to market within about a year.
    小题1:How should a driver respond to the sounds from Driver Alert?
    A．By sounding a warning.
    B．By touching the wristband.
    C．By checking the driving time.
    D．By pressing the steering wheel.
    小题2:We can learn from the text that the driver needs to stop for a break when his response time is ________
    A．about 400 milliseconds B．below 500 milliseconds
    C．over 500 milliseconds D．about 4 minutes
    小题3:When the driver gets sleepy while driving, Driver Alert ______.
    A．moves more regularly
    B．stops working properly
    C．opens the window for the driver
    D．sounds more frequently and loudly
    小题4:According to the text, Driver Alert ______.
    A．aims to reduce tiredness-related accidents
    B．has gone through testing at laboratories
    C．aims to prevent drivers from sleeping
    D．has been on sale for 12 months

    小题1:D
    小题2:C
    小题3:D
    小题4:A

    试题分析：在本文中作者介绍了一种新发明的、叫driver Alert的汽车装置，这种装置每四分钟发出一次声音，司机要通过按压方向盘来对此回应，以表明司机没有困倦，如果反应超过标准的时间，则说明司机疲劳驾驶，需要停车休息。这种装置目前正处于试验阶段，据说能减少20%--40%因疲劳而造成的意外。
    小题1:D细节理解题。根据文章第三段After each sound the driver must respond by squeezing the steering wheel(方向盘).可知司机听到Driver Alert所发出的声音时要按压方向盘，答案选D。
    小题2:C细节理解题。根据文章第四段a watchful driver would take about 400 milliseconds to respond, but once that falls to more than 500 milliseconds, it suggests that the driver is getting sleepy.可知司机需要休息的反应时间为500毫秒以上，答案选C。
    小题3:D细节理解题。从文章四、五段内容可知如果司机对Driver Alert 的声音反应不及时，就表明司机困倦了，在这种情况下这种装置就会发生均匀的、很大的声音以提醒司机，（In such cases the device gives out more regular and louder sounds）, 故D选项内容正确。
    小题4:A细节理解题。根据文章第二段The system, called driver Alert, aims to reduce deadly road accidents by 20%--40% that are caused by tiredness.可知这项装置的目的在于提醒司机，以减少因疲劳驾驶而发生的意外，答案选A。

    A book review tells not only what a book is about，but also how successful it is at what it is trying to do.Professors often assign book reviews as practice in careful analytical(分析的) reading.
    As a reviewer，you bring together the two strands of accurate，analytical reading and strong，personal response when you indicate(指出) what the book is about and what it might mean to a reader(by explaining what it meant to you)．In other words，reviewers answer not only the WHAT but the SO WHAT question about a book.Thus，in writing a review，you combine the skills of describing what is on the page，analyzing how the book tried to achieve its purpose，and expressing your own reactions.
    Most book reviews start with a heading that includes all the basic information about the book，like：
    Title.
    Author.
    Place of publication，publisher，date of publication.
    Number of pages.
    Like most pieces of writing，the review usually begins with an introduction that lets your readers know what the review will say.The first paragraph usually includes the author and title again，so your readers don’t have to look up to find this information.You should also include a very brief description of the contents of the book，the purpose or audience for the book，and your reaction and evaluation.
    Then you move into a section of background information that helps place the book in context and discusses how to judge the book.Next，you should give a summary of the main points，quoting(引用) and explaining key phrases from the author.Finally，you get to the heart of your review—your evaluation of the book.In this section，you might discuss some of the following issues：
    ?How well the book has achieved its goal.
    ?What possibilities are suggested by the book.
    ?What the book has left out.
    ?How the book compares with others on the subject.
    ?What specific points are not convincing.
    ?What personal experiences you’ve had related to the subject.
    It is important to use labels to carefully distinguish your views from the author’s，so that you don’t confuse your readers.
    Then，like other essays，you can end with a direct comment on the book，and tie together issues raised in the review in a conclusion.
    There is，of course，no set form，but a general rule is that the first one­half to two­thirds of the review should summarize the author’s main ideas and at least one­third should evaluate the book.
    小题1:According to the text，personal response of a book reviewer refers to “________”．
    A．accurate and analytical reading
    B．the reviewer’s indication of what the book is
    C．the reviewer’s indication of what the book meant to a reader
    D．skills of describing what is on the page
    小题2:What is the most important part of a book review?
    A．The heading.B．The evaluation.
    C．The conclusion.D．The introduction.
    小题3:Readers will get puzzled if ________.
    A．there is no heading in a book review
    B．the book review is not complex enough
    C．the reviewer’s point of view is mixed with the author’s
    D．there are some different issues listed in the book review
    小题4:What does the text mainly tell us?
    A．Steps to read a book.
    B．Tips for writing a book review.
    C．The way to develop your idea.
    D．Things not to be avoided in a book review.

    Growing strawberries in pots

    ·The best way to start growing strawberries is to buy pot-grown strawberry plants m spring：5plants are plenty for a hanging basket and 10 for the average 13 inch-sized pot．
    ·Plant them immediately in soil-based compost(混合肥料) and they will produce a modest crop in their first year．The second year should see a bumper(特大的)crop，followed by a slightly lower yield(产量)the third summer .Then start again with fresh stock
    ·Careful watering and feeding are essential Ifyou are to harvest a good crop，you must never
    let the compost dry out,particularly when the fruit is forming and ripening；if you do．most of your
    crop will drop off血e bush almost immediately．
    ·Water well then leave the pots for up to 3 weeks，until they reach the point of drying out Be
    Careful not to overwater them during the winter months．
    Pruning apple trees
    ·A one-year-old tree is known as a “maiden”. It has a single stem when purchased. Immediately after planting, cut it back by about half to leave 4 good buds at the base of the stem.. This will force growth from the base or the plant during the summer.

    ·In the second year ,prune in winter by cutting all side branches back by about one-third, Make sure each cut is made cleanly just above an outward-facing bud. In the third and fourth years, new side branches will have emerged from the previous year’s growth. Cut back all these new side branches by a third, pruning to an outward-facing bud.
    ·By the fifth year the tree should have a well-balanced shape. From then on ,cut back all new branches by one-third in winter .Remove any diseased wood and broken branches, and ensure the centre is open to air circulation

    It is generally believed that we are getting cleaned when we step under a shower. We are, but we’re also giving a home to lots of tiny little creatures we didn’t even know about. A showerhead carries thousands of bacteria called Mycobacterium．These can cause problems like coughs and tiredness, and a general feeling of poorliness (身体不舒服). When you turn on the water, the bacteria go from the showerhead onto and into your body.
    This is a finding of Norman R. Pace and his team at the University of Colorado, in the US. The scientists investigated bacteria in all kinds of human environment, including showers．Pace's team looked at 45 showerheads in nine American cities. They discovered that 30 percent of them had large amounts of flying Mycobacterium.
    But Pace said that they pose few threats to the health．Only those with a weak immune system might need to worry．He told the New York Times that the bacteria are not as unpleasant as might be thought．He said that having a shower is no more dangerous than anything else we do in the morning．
    But for those who feel sick about the idea of all those microorganisms (微生物), he had some advice. Let the water run for 30 seconds before getting into the shower. Why? The number of bacteria is smaller than that when the water is just turned on. If that seems like a waste of water, he added that you could also change your showerhead every few months.
    However, Pace had good news too. He has also been testing the air in US subways. Apart from iron particles (粒子), which are ground off the track by the wheels of trains, subway air is fresh. The reason is that a train’s movement pumps fresh outdoor air into the tunnels.
    Pace explained that he wanted to understand the natural microbial environments of public places. This kind of knowledge might help discover the microbes to be used in a bioterrorist (生物恐怖分子) attack.
    小题1:From the finding of Norman R. Pace, after taking a shower, we might cough or feel tired because      .
    A．it’s easy to get a cold when taking a bath
    B．the showerhead carries many bacteria causing illness
    C．we don’t get cleaned while showering
    D．we don’t get a weak immune system
    小题2:According to the passage, which of the following is TRUE?
    A．Hot water could kill most of bacteria in showerheads.
    B．Of 45 showerheads surveyed in nine cities, 30 carried large amounts of Mycobacterium.
    C．Changing showerheads is the only way to avoid microorganisms.
    D．Shower water contains much less bacteria after being left to run for 30 seconds.
    小题3:We can learn from the third paragraph that       .
    A．having a shower in the morning is more dangerous than at other time
    B．the bacteria always threat people’s health
    C．there is no reason to fear microorganisms for people with strong immune system
    D．it is better to do some exercise in the morning than have a shower
    小题4:The underlined word “pose” in the third paragraph probably means “______”．
    A．cause B．avoid C．describeD．promise
    小题5:What contributes to fresh air in US subways?
    A．The train’s movement.B．Iron particles．
    C．Train wheels.D．Air conditioners on the trains．

    Meet the “Tutor Kings and Queens”
    “If you want to be a top tutor, it definitely helps if you are young and attractive. Students look at your appearance，” said Kelly Mok, 26, a “tutor queen” at King's Glory, one of Hong Kong's largest tutorial establishments.
    Richard Eng from Beacon College, a former secondary school teacher, is often credited with being the first of Hong Kong's “star tutors”. “In school all the teachers look the same, there's no excitement，” he said.
    The celebrity tutor phenomenon is a result of the huge growth in out­of­school tutoring in Asia. It is fuelled by highly pressured examination systems and ambitious parents wanting their children to secure places at top universities and high­status secondary schools.
    In societies where success is_equated_with good exam results, parental anxiety converts into a “steady stream of revenue(收入)” for tutoring establishments, according to a study by the Asian Development Bank (ADB)．
    The tutoring industry, or “shadow education” as the ADB calls it, has become very widespread in Asia, fed by the growth in universities and the rising proportion of school leavers aiming for university. Hong Kong University's professor Mark Bray, one of the authors of the ADB study, said a staggering 72% of final­year school students in Hong Kong now go to private tutors.
    It's not just Hong Kong. Tutoring has “spread and intensified(强化) in Asia and become more commercialized，” said Professor Bray. In South Korea, 90% of primary school children attend such classes. In China, New Oriental Education and Technology has grown to become one of the largest tutoring schools in Asia with around 2.4 million students this year. In South Korea, Thailand, Sri Lanka and India, tutorial schools use star tutors to attract even more students.
    小题1:According to Kelly Mok, tutors ________.
    A．have a lot in common with school teachers
    B．benefit much from their appearances
    C．become more and more popular in the world
    D．have much more pressure than in the past
    小题2:Who is probably a “tutor king” in Hong Kong?
    A．Kelly Mok.B．Richard Eng.
    C．Mark Bray.D．Not mentioned.
    小题3:What Professor Bray says in this passage means that ________.
    A．the number of school leavers is increasing
    B．tutoring may improve achievement for individual students
    C．star tutors have attracted 2.4 million students
    D．more and more students in Asia go to private tutors
    小题4:The underlined part in Paragraph 4 is similar in meaning to ________.
    A．is equal toB．leads to
    C．results inD．is different from
    小题5:Where is this passage probably taken from?
    A．An English newspaper.B．A travel guide.
    C．A fashion magazine.D．A physics book.

    Around the world coral reefs(珊瑚礁) are facing threats(威胁) brought by climate change and great changes in sea temperatures. While ocean warming has been the primary focus for scientists and ocean policy managers, cold events can also whiten corals. A new study by scientists compared damaged to corals exposed to heat as well as cold stress. The results show that cool temperatures can cause more damage in the short term, but heat is more destructive(破坏性的) in the long run.
    Climate change is widely known to produce warming conditions in the oceans, but extreme cold-water events have become more frequent and serious as well. In 2010, for example, coral reefs around the world faced on of the coldest winters and one of the hottest summers on record.
    During a unique experiment, corals under cold temperatures suffered greater damage in just days compared with heat treated corals. Yet the researchers found that corals were eventually able to adjust to the cold conditions, make their health stable and continue to grow. However, over the long term corals subjected to heat suffered more greatly than those in cold, with evidence of severe whitening and growth stoppage, which leads to death.
    The coral’s ability to adjust to cool temperatures surprised the researchers, who say the study’s results show the complexities(复杂性) of monitoring coral health in response to different environmental factors(因素).
    “Global warming is associated with increases but also decreases of temperatures,” said Deheyn, one of the researchers. “Not much has been known about the comparative effects of temperature decrease on corals. These results are important because they show that corals react differently to temperature differences, which is important for future management of coral reefs in the field of climate change.”
    小题1:Which of the following is TRUE according to the passage?
    A．Corals are unable to adjust to temperature changes.
    B．Cold temperature causes greater damage to corals.
    C．Hot temperature helps coral reefs to grow quickly.
    D．Heat and cold damage corals in their own ways.
    小题2:We can learn from the passage that         .
    A．scientists used to pay no attention to the effect of cold events on corals
    B．2010 witnessed one of the greatest temperature differences on record
    C．corals prefer warmer conditions to cold temperatures in the long run
    D．global warming has nothing to do with the decrease of temperature
    小题3:According to the research,            .
    A．corals may continue to grow in cold events after a few days
    B．cold events help corals grow more quickly in a short time
    C．corals show no response to hot temperatures in the first days
    D．corals are whitened mainly because of warm temperatures
    小题4:Scientists reached the conclusion through              .
    A．news reportB．scientific studyC．great imaginationD．natural conditions

    New crime prediction software should reduce not only the murder rate, but the rate of other crimes. Developed by Richard Berk, a professor at the University of Pennsylvania, the software has already used in Baltimore and Philadelphia to predict which individuals on probation(缓刑) or parole(假释) are most likely to murder and to be murdered.
    “When a person goes on probation or parole he is supervised(监督) by an officer. The question is ‘what level of supervision is appropriate?’” said Berk. It used to be that parole officers used the person’s criminal record, and their judgment to make decisions.
    “This research replaces those seat-of-the –pants calculations,” he said.
    Technology helps determine level of supervision. On average there is one murder for every 100,000 people. Even among high-risk groups the murder rate is one in 100. Predicting such a rare event is very difficult, but advances in computer technology works.
    Years ago, the researchers made a dataset of more than 60,000 various crimes. Using the software they developed, they found some much more likely to commit murder when paroled or probated. They could identify eight future murderers out of 100.
    Berk’s software examines roughly two dozen variables(可变因素), from criminal record to geographic location. The type of crimes, and more importantly, the age at which that crime was committed, were two of the most predictive variables.
    “People assume that if someone murdered then they will murder in the future,” said Berk. “ What really matters is what that person did as a young individual. Predicting future crimes sounds well. But we aren’t anywhere near being able to do that.”
    “Berk’s scientific answer leaves policymakers with difficult questions. By labeling one group of people as high risk, and supervise them closely, there should be fewer murders, which the potential victims should be happy about. It also means that those high-risk individuals will be supervised more aggressively. For human rights advocates, that means punishing people who, most likely, will not commit a crime in the future,” said Bushway. “It comes down to a question of whether you would rather make these errors or those errors.”
    小题1:The underlined words(in Para.3) probably mean___. 
    A．calculations based on subjective opinions
    B．calculations based on widespread voting
    C．calculations made by advanced technology
    D．calculations based on serious considering
    小题2:For 650 people with crime records, how many potential murderers would the software find?
    A．6.5.B．13.C．52.D．65.
    小题3:From Para 7, we can infer that______.
    A．the technology developed by Richard Berk will soon be widely used in the US
    B．the technology would not be widely accepted in the short term
    C．whether a person murders or not largely decided by his upbringing while young
    D．if a person murdered when he was fifty, he is sure to murder again while on probation
    小题4:Bushway’s attitude to the technology put forward by Richard Berk is ____.
    A．positiveB．negativeC．objectiveD．indifferent
    小题5:Which would be the best title for the passage?
    A．Closely Supervise Potential Murders
    B．Measures Taken to Prevent Criminal Behavior
    C．Technology Revolutionizes Judges’ Way of Working
    D．Software is Developed to Predict Criminal Behavior

    Chinese parents are very generous when it comes to educating their children. Not caring about the money, parents often send their children to the best schools or even abroad to England, the United States or Australia. They also want their children to take extra-course activities where they will either learn a musical instrument or ballet, or other classes that will give them a head start in life. The Chinese believe that the more expensive an education is, the better it is. So parents will spend an unreasonable amount of money on education. Even poor couples will buy a computer for their son or daughter.
    However, what most parents fail to see is that the best early education they can give their children is usually very cheap.
    Parents can see that their children’s skills vary, skilled in some areas while poor in others. What most parents fail to realize, though, is that today’s children lack self-respect and self-confidence.
    The problem is that parents are only educating their children on how to take multiple-choice tests and how to study well, but parents are not teaching them the most important skills they need to be confident, happy and clever.
    Parents can achieve this by teaching practical skills like cooking, sewing and doing other housework.
    Teaching a child to cook will improve many of the skills that he will need later in life. Cooking demands patience and time. It is an enjoyable but difficult experience. A good cook always tries to improve his cooking, so he will learn to work hard and gradually finish his job successfully. His result, a well-cooked dinner, will give him much satisfaction and a lot of self-confidence.
    Some old machines, such as a broken radio or TV set that you give your child to play with will make him curious and arouse his interest. He will spend hours looking at them,tying to fix them ,your child might become an engineer when he grows up. These activities are not only teaching a child to read a book, but rather to think, to use his mind. And that is more important.
    小题1:Parents in China according to this passage    .
    A．are too strict with their children
    B．are too rich to educate their children
    C．have some problems in educating their children correctly
    D．have no problems in educating their children strictly
    小题2:The writer of the passage does not seem to be satisfied with    .
    A．the parents’ ideas of educating their children
    B．the education system of the school
    C．children’s skills in cooking at home
    D．children’s hobbies in the classroom
    小题3:Doing some cooking at home helps children    .
    A．learn how to serve their parents
    B．learn how to become strong and fat
    C．get a lot from it and prepare themselves for the future
    D．make their parents believe that they are clever
    小题4:According to the last paragraph we can conclude that    .
    A．broken radios and television sets are useful
    B．one’s interest and curiosity may be useful for his later life
    C．an engineer must fix many broken radios

    Where Are We Going, Dad? presents a new generation of men, in a break from Chinese tradition, now take an active role in their children's lives.
    Five star fathers and their children travel around China, riding camels through the western deserts, fishing off the east coast, and selling vegetables for their bus fare home in remote southwestern Yunnan province. One dad doesn’t know how to do his daughter’s hair, but give him a couple of days — he’ll figure it out. Another one must survive with his son for three days in the desert, where, because neither can cook, the two only eat instant noodles.
    These story lines are part of Where Are We Going, Dad? which, since its first show in October, has become one of China’s most popular television shows, covering more than 600 million viewers each week. And searches for Where Are We Going, Dad? turn up over 40 million hits on Sina Weibo, China’s Twitter.
    “In traditional Chinese culture, the common conception of parenthood is that the father is strict and the mother is kind. But on the show, we see fathers who are much gentler on their kids and more concerned with their upbringing,” said Li Minyi, an associate professor of early childhood education at the leading Beijing Normal University. “An important question arises in this show for modern Chinese society — what is the role of fathers in today’s China?”
    “As they raise their children, parents are growing up at the same time,” said Wang Renping, a popular education expert, in an interview with the Qianjiang Evening News. “They cannot use parenting styles from 20 years ago to guide the development of children born 20 years later.”
    The attraction of Where Are We Going, Dad? lies in the chance to have a close look at the lives of popular Chinese stars and their children. Audiences fancy watching the failed attempts of star dads making dinner, braiding hair(编头发), and disciplining children — tasks often left to mothers in a society still influenced by the opinion that “men rule outside and women rule inside.”
    小题1:From the passage, we can draw a conclusion that Where Are We Going, Dad? is         .
    A．a TV showB．a novelC．a matchD．a news report
    小题2:In Where Are We Going, Dad, we can probably learn about                          .
    A．how the fathers do housework at home
    B．how the children study in their spare time
    C．how the fathers look after and guide their children
    D．how the children help their father with their travel around China
    小题3:Which of the following is RIGHT according to the passage?
    A．In modern society, men should not care too much about their kids.
    B．Where Are We Going, Dad has the most number of viewers in China.
    C．In Chinese tradition, fathers always play an active part in their children’s lives.
    D．While they bring up their children, parents are improving their parenting styles.
    小题4:The reason why Where Are We Going, Dad is so popular in China may include the following EXCEPT that          .
    A．audiences enjoy laughing at others’ failure in life
    B．it can make people laugh and think at the same time
    C．people love watching the stars and their children’s lives closely
    D．it presents a new generation of men’s role in their children’s lives
