    In many parts of the world cars play an essential role in daily life and many societies would stop to function without them. So the claim that in 20 years’ time no one will own cars may be hard to believe. But this is the prediction made by a team of transport researchers who are taken seriously not only by governments but also by car manufacturers.
    The Human Science and Advanced Technology Institute at Loughborough in the UK is part of an international research program. The team there believes that by 2020 all cars will be computerized, which will mean extremely large fuel savings, no accidents and better use of roads. The super-intelligent car of the 21st century will drive itself and it will not be owned by on individual. Instead, we will have a choice of cars and change them as frequently as we change our clothing.
    According to Dr. David Davis, who leads the research team, these predictions are based on the rising cost of the car culture ,which had blocked up our cities, polluted our air and caused more deaths than both world wars put together.
    Davis says cars will be fitted with intelligent cruise control devices to regulate the distance between one car and another. Brakes and accelerators (加速器) will become redundant（多余的） because the car will automatically speed up or slow down to match the speed of the car in front. Computers are much safer drivers than people, so cars in a road train will be able to drive much closer together than cars driven by people.
    By 2010 Dr. David Davis believes car technology will give motorists a clear view of the road whatever the weather conditions by projecting an image of the road ahead onto the car’s windscreen. And by 2020 cars will travel in convoy linked to each other electronically. Cars will be connected by an electronic tow(牵引) bar to the car in front to form “road-trains”. “The front vehicle in such a train burns the ordinary fuel” says Davis. “But all the others in the train would burn about ten percent of the normal amount and so produce about ten percent of the pollution.
    小题1:We know from the passage that governments and car manufactures ________.
    A．don’t believe the prediction that no one will own cars by 2020.
    B．are devoted to the technological innovation (创新) in car industry.
    C．consider the predictions made by the researchers seriously.
    D．have put the super-intelligent car into mass production.
    小题2:Which of the following will NOT be the characteristics of the cars of 2020 ?
    A．There will be no brake and accelerator in cars.
    B．We will own as many cars as we want .
    C．All cars will be driven by computers.
    D．Car accident will no longer happen.
    小题3:The expression closest in meaning to the underlined phrase “ in convoy”(Para 5) is ______.
    A．in lineB．sidelongC．side by sideD．next to one another
    小题4:What will happen if cars are linked to each other electronically in 2020 ?
    A．Motorists will get a clear view of the road.
    B．The weather conditions won’t have effect on motorists.
    C．There will be a decrease in the pollution caused by car .
    D．All trains will burn less fuel than present.

    Directions: For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.
    As we all know, Chinese handwriting has infinite power to express differences of character and cultivation. But we have to admit that traditional handwriting has become a __50__ art, now that kids start using keyboards as soon as they begin school. However, writing things out by hand may be a __51__ way we train our brains, several studies suggest. Many psychologists think that handwriting can make you __52__!
    Writing by hand is different from __53__ because it requires using strokes to create a letter, __54__ just selecting the whole letter by touching a key, says Virginia Berninger, a professor of psychology at the University of Washington. These __55__ movements activate large regions of the brain __56__ in thinking, memory, and language. Handwriting helps children learn letters and shapes, improves their composition of ideas, and may also __57__ fine-motor skills development.
    A study by Berninger found that in grades two, four, and six, children wrote more words, faster, and expressed more __58__ when writing essays by hand than when typing on a keyboard.
    A separate study by researchers at Indiana University found that children who practiced printing by hand had more active__59__than kids who __60__ looked at letters.
    It’s not just children who __61__ from writing things out by hand, says a study in the Journal of Cognitive Neuroscience. Adults learning a new language remember its __62__ better if they write them out by hand than if they produce them with a keyboard.
    As more people __63__ their days on the computer, says neuroscientist P. Murali Doraiswamy of Duke University, “__64__ people in handwriting skills could be a useful cognitive exercise.”

    Popeye the Sailor first became a popular cartoon in the 1930s.The sailor in that cartoon ate lots of spinach to make him strong. People watched him, and they began to buy and eat a lot more spinach. Popeye helped sell 33 percent more spinach than before! Spinach became a necessary part of many people’s diets. Even some children who hated the taste began to eat the vegetable.
    Many people thought that the iron in spinach made Popeye strong, but this is not true. Spinach does not have any more iron than any other green vegetable.
    People only thought spinach had a lot of iron because the people who studied the food made a mistake. In the 1890s, a group of people studied what was inside vegetables. This group said that spinach had ten times more iron than it did. The group wrote the number wrong, and everyone accepted it.
    Today, we know that the little iron there is in spinach cannot make a difference in how strong a person is. However, spinach does have something else which the body needs—folic acid.
    It is interesting to point out that folic acid can help make a person strong. Maybe it was really the folic acid that made Popeye strong all along.   
    小题1: Why did many people eat spinach after they saw Popeye the Sailor?
    A．They thought spinach made them strong.B．They thought Popeye was funny.
    C．Spinach had a lot of iron.D．People liked folic acid.
    小题2: A research group told people that spinach____.
    A．made Popeye strong
    B．was a green vegetable
    C．had less iron than other green vegetables
    D．had more iron than other green vegetables
    小题3:The reading passage says that perhaps Popeye got his strength from____.
    A．ironB．folic acidC．spinachD．exercise
    小题4:Folic acid is ____.
    A．something in foodB．a vegetableC．dangerousD．a certain kind of spinach

    When coal is burned in a boiler, two kinds of ash by-products are produced: a heavy bottom ash and a fine-as-powder fly ash. About 10 to 15 percent of the coal by-product is bottom ash which is used like sand on streets and highways covered with ice, and also on highways as paving material.
    It is the fly ash, however, that is receiving much attention. Once considered a waste, fly ash is now regarded as a natural resource in the United States. It can be placed in some lower places, where it is compacted and covered with soil, for the seeds of various grasses and plants to be placed in the soil to make the land productive.
    Fly ash may be added to concrete to build roads and other kinds of buildings, taking the place of the cement up to 20 percent. As a by-product of burned coal, fly ash requires no extra energy to be produced, while cement production requires great amounts of energy.
    Besides, the technology is able to take out some useful minerals from the fly ash, which is still a very expensive process today. But the time may come when it is cheaper to take out these products from ash than to mine new supplies.
    小题1: The bottom ash can be put on icy streets________.
    A．in order to rebuild themB． in order to make them colourful
    C．so that people can walk on themD．so that cars can run faster
    小题2:The fly ash_______ bottom ash.
    A．has the same use asB． is more expensive than
    C．has more uses thanD．is much cheaper than
    小题3:The fly ash can be used to________.
    A．grow various plantsB． take the place of soil
    C．cover productive landD．make more productive land
    小题4: Which of the following is right?
    A．To produce fly ash, some extra coal is to be burned.
    B． Fly ash is made while producing cement.
    C．It takes less energy to produce fly ash than cement.
    D．Fly ash is a costless by-product.
    小题5:The word “mine” in the last sentence of the passage means_______.
    A．to buy things from other countries
    B． to search for useful materials in the mountains
    C．to dig deeply into the ground to get useful materials
    D．to take out certain materials from other things

    October 15th is Global Handwashing Day.  Activities are planned in more than twenty countries to get millions of people in the developing world to wash their hands with soap.
    Experts say people around the world wash their hands but very few use soap at so-called critical moments. These include after using the toilet, after cleaning a baby and before touching food.
    Global Handwashing Day is the idea of the Public-private Partnership for handwashing with soap. The goal, they say, is to create a culture of handwashing with soap. The organizers say all soaps are equally effective at removing disease-causing germs （细菌）. They say the correct way to wash is to wet your hands with a small amount of water and cover them with soap. Rub it into all areas, including under the fingernails. Then, wash well under running water. Finally, dry your hands with a clean cloth.
    The Partnership says soap is important because it increases the time that people spend washing. Soap also helps to break up the dirt that holds most of the germs. And it usually leaves a pleasant smell, which increases the chances that people will wash again.
    It also says that washing hands with soap before eating and after using the toilet could save more lives than any medicine. It could help reduce cases of diarrhea （痢疾）, which is the second leading cause of child deaths, killing more than one and a half million children a year, by almost half.
    小题1:What does the author intend to tell us in the passage?
    A．To keep healthy by washing hands.B．To wash hands with soap.
    C．To take action to wash hands.D．To wash hands often.
    小题2:Which of the following is the right way to wash hands?
    a. Washing hands well.                b. Covering hands with soap.
    c. Drying hands.                     d. Rubbing hands with soap.
    e. Wetting hands.
    A．a--c--b--e--dB．e--d--a--b--c
    C．a--c--b--d--eD．e--b--d--a--c
    小题3:Which fact can’t explain why soap is important?
    A．It gives people a longer handwashing time.
    B．It helps to remove a lot of germs from hands.
    C．It attracts people to do more handwashing.
    D．It gets all people into the habit of washing hands.
    小题4:According to the last paragraph, diarrhea is a disease that ________.
    A．kills half of the kids in the developing countries a year
    B．causes the greatest number of child deaths
    C．can be prevented to some degree by washing hands with soap
    D．can’t be cured without washing hands

    In Canada you can find dogs, cats, horses, etc. in almost every family. These are their pets. People love these pets and have them as their good friends. Before they keep them in their houses, they take them to animal hospitals to give them injections(注射)so that they won't carry disease. They have special animal food stores, though they can get animal food in almost every kind of store. Some people spend around two hundred Canadian dollars a month on animal food. When you visit people's houses, they would be very glad to show you their pets and they are very proud of them. You will also find that almost every family has a feeding place for birds in their garden. All kinds of birds are welcomed to come and have a good meal.

    C
    By far the most common difficulty in studying is simple failure to get down to regular concentrated work. This difficulty is much greater for those who do not work to a plan and have no regular routine of study. Many students muddle (胡乱对付) along, doing a bit of this subject or that, as the mood takes them, or letting their set work pile up until the last possible moment.
    Few students work to a set timetable. They say that if they did work out a timetable for themselves they would not keep to it, or would have to change it frequently, since they can never predict from one day to the next what their activities will be.
    No doubt some students are more willing to accept a regular routine than others. There are many who shy away from a self-controlled weekly timetable, and dislike being tied down to a fixed program of work. Many able students state that they work in cycles. When they become interested in a topic, they work on it attentively for three or four days at a time. On other days they avoid work completely. It has to be admitted that we do not fully understand the motivation (动机)to work.. Most people over 25 years of age have become used to routine, and the majority of real productive workers set aside regular hours for the more important areas of their work. The “tough-minded” school doesn’t fully accept the idea that good work can only be done naturally, under the influence of inspiration.
    Those who believe that they need only work and study as the fit takes them have a mistaken belief either in their own talent or in the value of “freedom”. In fact, freedom from control and discipline（纪律）leads to unhappiness rather than to “self-expression” or “personality development”. Our society insists on regular habits, timekeeping and punctuality (准时), and whether we like it or not, if we mean to make our way in society, we have to meet its demands.
    小题1:The most widespread problem in applying oneself to study is ______.
    A．changing from one subject to another
    B．the failure to keep to a set timetable of work
    C．the unwillingness to follow a systematic plan
    D．working on a subject only when one feels like it
    小题2:Which of the following is true?
    A．Many students are not interested in using self-controlled timetable.
    B．Many students don’t like being told to study to a fixed timetable.
    C．Most people of over 25 years of age don’t work to a set timetable.
    D．Tough-minded people agree that good job is done naturally
    小题3:The underlined part “as the fit takes them” in paragraph 4 probably means ______.
    A．when they have the energy
    B．when they are in the mood
    C．when they feel fit
    D．when they find conditions are suitable
    小题4:A suitable title for the passage might be ______.
    A．Attitudes to StudyB．A study Plan
    C．The Difficulties in StudyingD．Study and Self-discipline

    The national assistance system for poor college students is getting more effective as proved by fewer phone calls to the hotline of the National Center for Student Assistance Administration.
    "Poor college students and their parents are getting more satisfied with the national assistance system," said Ma Wenhua, deputy director of the administration, on Saturday. Over the past three years, the hotline received 8,488 calls. Statistics show 62 percent of the calls were made to ask about the funding policy, while 38 percent (3,200 calls) complained local colleges had failed to abide by the rules to support the students.
    Complaints were seen a year-on-year decrease from 2006 to 2008. Ma said some poor families might still overlook what they should do to get support for their child. To ensure education equality, the government has introduced a set of favorable policies to help poor students, such as scholarships, grants(助学金), student loans, tuition waivers(学费全免) and the work-study programs under which poor students are helped out in libraries, teachers' offices or service departments to earn money.
    Statistics show the government spent 29.3 billion yuan last year to aid college students, up 7.6 percent from the previous year. Around 40 million persons of college students received the national aid.
    The Ministry of Education of the government would ensure that no students drop out of colleges or universities because of poverty.
    Among the 20 million students in the country's public and private universities and colleges last year, about 20 percent came from poor backgrounds, official figures show.
    小题1:The national assistance system is set up ___.
    A．for parents and students to complain
    B．to help poor college students
    C．for poor students to get free education
    D．to help students find jobs
    小题2:The underlined phrase "abide by" in the second paragraph probably means ____.
    A．followB．breakC．bearD．agree to
    小题3:From the passage, we know that ____.
    A．students will drop out of university because of poverty
    B．Chinese poor college students are more satisfied with national assistance system
    C．more and more parents are complaining about their local colleges
    D．college students are suffering from great economic pressure

    Mother’s Day is usually celebrated on the second Sunday of May every year. Do you know that a mom deserves a special gift this year for Mother’s Day? Sure, flowers can always brighten Mother’s Day and a dinner out is always appreciated. However, doesn’t she deserve something more personal or something that lasts longer than an evening?
    I’m talking about the gift of fitness. Improved fitness is a gift that is invaluable to everyone. When you give a woman the gift of fitness, you are helping her open her door to better health.

She may be more motivated to actually get fit because she doesn’t want to feel guilty about ignoring such a thoughtful gift.
