    One of the world's richest men has taken a close interest in one of man’s most basic functions: visiting the toilet．Bill Gates’s charitable organization, the Bill and Melinda Gates Foundation, is looking for inventors to design the loo of the future, which, they hope, would improve sanitation for millions of people around the world．
    So, what's wrong with the traditional flush toilet? Firstly, it wastes a huge amount of potential drinking water．Secondly, they are more likely to cause pollution．This is a real problem in many areas of the developing world, where, according to United Nations estimates, unsafe sanitation causes half of all hospitalizations．Younger people are particularly at risk．Illnesses which cause diarrhea are responsible for the deaths of about 1.5 million children a year．Finally, standard lavatories simply aren’t practical in remote areas．
    The challenge set by Bill Gates was to come up with a latrine which works without running water, electricity or aseptic tank(化粪池)．It also needed to operate for less than 5 cents．28 designs were displayed at the recent Reinvent the Toilet Fair in Seattle, USA．Among them was one which turned human waste into electricity using microwaves, another which converted human waste into charcoal, and yet another which used urine for flushing．
    But the winner was a solar-powered design which generated hydrogen gas and electricity.The team from the California Institute of Technology（CIT）picked up a prize of $ 100,000.
    But clearly Bill Gates doesn’t feel he’s flushing money down the toilet．After the Seattle event he said, “We, couldn’t be happier with the response we’ve gotten,” Gates has even pledged $370m more to the future toilet project．They hope to field test more prototypes over the next three years．
    小题1:Why is Bill Gates paying people to invent new toilets?
    A．Because he wants to test people’s sense of creativity．
    B．Because he wants to improve sanitation for many people．
    C．Because he thinks the traditional ones are out of fashion．
    D．Because he can’t design this kind of things himself．
    小题2:Which of the following is NOT a problem with the traditional flush toilet?
    A．They waste too much water．
    B．They might cause diseases．
    C．They are not always practical．
    D．They are too complicated to use.
    小题3:The underlined word “latrine” in the third paragraph might have similar meanings to the word “__ ”n the text．
    A．LooB．sanitationC．diarrheaD．prototype
    小题4:The team from CIT won the prize because their design        .
    A．can change human waste into electricity
    B．can turn human waste into charcoal
    C．can produce power with solar energy
    D．can use urine for flushing
    小题5:If someone “flush money down the toilet”, they are       .
    A．showing off their wealth
    B．being angry with their work onditions
    C．wasting money for nothing
    D．expressing their great determination

    小题1:B
    小题2:D
    小题3:A
    小题4:C
    小题5:C

    试题分析：这篇文章讲了世界首富比尔盖茨对厕所的功能很感兴趣，由于现在的抽水马桶存在很多弊端，所以他们正在研发未来的厕所。
    小题1:根据Bill Gates’s charitable organization, the Bill and Melinda Gates Foundation, is looking for inventors to design the loo of the future, which, they hope, would improve sanitation for millions of people around the world．故选B。
    小题2:根据Firstly, it wastes a huge amount of potential drinking water．Secondly, they are more likely to cause pollution．This is a real problem in many areas of the developing world, where, according to United Nations estimates, unsafe sanitation causes half of all hospitalizations．Younger people are particularly at risk．Illnesses which cause diarrhea are responsible for the deaths of about 1.5 million children a year．Finally, standard lavatories simply aren’t practical in remote areas．故选D。

    A 70-year study of personality suggests that pessimism is a risk factor for early death, especially among men.
    　　The study results also indicate that pessimism can be linked to increased risk for sudden death from accidents or violence, according to the report published in the March issue of Psychological Science.
    　　Christopher Peterson of the University of Michigan and his colleagues analyzed data from the Terman Life-Cycle Study, which began by studying California public-school children with high IQs in 1921 and followed them through their life. Most of the 1,528 children were teenagers when the study began. Those still living are now in their 80s. In 1936 and 1940, participants were asked to complete a questionnaire designed to obtain information about difficult life events and their effect on overall outlook. One such question was, “What do you regard as your most serious fault of personality or character?”
    　　Pessimists were defined as fatalistic(宿命论的)people who tend to blame themselves when things go wrong and who believe that one bad event can ruin the rest of their life. They also tend to expect bad things to happen to them and feel that they have little or no ability to change their situation.
    　　Males were more likely than females to be classified as pessimistic. Compared with individuals with a more cheerful and optimistic outlook, pessimists were more likely to die from accidents and violence (including suicide).
    　　A pessimistic personality may lead to poor problem-solving ability, social difficulties and risky decision-making. Taken together, these variables put the pessimist at higher risk of untimely(不适时的) death, say the researchers. Such a person is less likely to avoid or escape potentially dangerous situations, the researchers concluded. “A pessimistic way of thinking in which people worry too much about bad events, predicts untimely death decades later,” according to Peterson.
    小题1:According to the passage, you may be a pessimistic person, if one failure makes you feel________.
    A．other people have been unfair to you.
    B．other people will help you.
    C．you cannot change a bad situation.
    D．you can do better next time.
    小题2:According to the passage, pessimists may feel all of the following EXCEPT________
    A．helpless when faced with difficulties.
    B．cheerful when faced with troubles.
    C．hopeless when one bad event occurs.
    D．guilty when things go wrong.
    小题3:Which of the following statements is true, according to the passage?
    A．Pessimists believe that everything in life depends on fate.
    B．There are more pessimists among women than among men.
    C．Most pessimists will end up committing suicide.
    D．All pessimists will eventually die from accidents.
    小题4:The Terman Life-Cycle Study is a research program that studies________.
    A．people over 70 years old.
    B．people since their childhood.
    C．pessimistic people over 80 years old.
    D．only younger people.
    小题5:The analysis made by Christopher Peterson and his colleagues shows that pessimistic people________
    A．will die from violence if they learn to be optimistic.
    B．will more likely die from violence than optimistic people.
    C．will die from violence because their IQs are low.
    D．will die untimely if they are not able to learn to be cheerful and optimistic.

    Due to the increasing number of violent acts produced in schools all over the world, more and more parents prefer to have their children educated at home rather than at school. This way they can assure their safety and well-being. Teachers and school representatives are trying to improve the situation in schools by increasing the number of the persons charged with the safety of the students.
    The main reason for violent acts are the films and cartoons that fill the children’s time. They want to do everything. They watch on TV and never think of the results, and they may hurt a classmate or a teacher.
    On the other hand, parents are not fully satisfied with the children’s results obtained in classes and they consider private classes would have better results.
    When a teacher has to watch 30 students in class he can’t probably see what each of them is doing, how he is writing, or if he understands the explanations. At home the teacher can explain in detail everything the child doesn’t understand as many times as he considers proper.
    And many times, the child grows fond of the teacher at home, who becomes his best friend, and who helps him whenever he needs someone to talk to. 
    However, the best solution would be a mixture between the education received at school and that at home, because school makes children communicate and socialize. Keeping a child at home for fear that something bad might happen to him only makes the child’s character weak and prevents him from knowing what real life is. Staying in a glass bowl only does harm to the child.
    All in all, schools have been created to help children, not to harm them, so it’s best to keep children in these special places, where they learn, laugh, have fun and make new friends.
    小题1:The writer’s purpose in writing the text is to      .
    A．teach parents the ways to keep theft children safe
    B．show solutions to developing children’s character
    C．explain the main reason for violence acts in schools
    D．analyze an education problem and give opinions.
    小题2:What does “a glass bowl” in the passage refer to?
    A．A toy that can be used for entertainment．
    B．A safe and comfortable environment．
    C．An object that is made of crystal．
    D．A setback that is hard to overcome．
    小题3:We can infer from the passage that      .
    A．violent TV programs have bad effects on children’ behavior
    B．the teacher at home is more patient than the teacher at school
    C．children today are weak from lack of sense of right and wrong
    D．there are too many students in class for a teacher to teach

    The home of the future won’t be completely different and we will be living in houses and flats just as we do today．But people will want to shape their homes to match their dreams．No two homes will be the same．People will be able to buy “house kits” containing a basic house structure, with movable walls, doors and windows．They will put together the different parts to create the home they want．
    Many jobs that we do today will disappear, others will still exist but will change and new jobs will be created. Skilled workers such as builders, gardeners and electricians won’t disappear because machines can’t replace them. Teachers will still exist because students need human contact. But they will be using modern technology in class more and students will be working more from home. The medical technology revolution and space travel will create new jobs which we can only imagine today．
    Space holidays will develop in the future, but these holidays won’t be for everyone because they won’t be cheap. Short space trips will develop first, then space hotels will orbit the earth where it will be possible to have a longer vacation. By the end of the next century, there will be holiday centres on the moon with leisure facilities for families．
    Paper won’t exist in the future. Instead, there will be e-paper which people will be able to use over and over again. This will develop in order to save natural resources. E-newspapers and e-magazines will replace traditional newspapers and magazines and we will download information and news articles from the Internet every day onto our reuseable paper．
    The laws of physics tell us that the earth is going to disappear some time in the future．This isn’t going to happen tomorrow but scientists predict that it will happen in five billion years when our sun explodes (爆炸)．We will have to explore the universe and find another home. At some point in the distant future, either we stay on the earth and die with it, or we leave and move to another planet. There won’t be any other choice.

    As the father of a student, I have experienced first hand what a great teacher is. My son was in the 4th grade last year, and he had a teacher called Miss Green. I believe that when he is an adult he will surely look back on her as the best teacher he has ever had.
    My son has attention deficit disorder(注意力缺损症) that makes it a little more difficult for him to learn. She was able to change her teaching methods for him so that he could keep up with the rest of the class. As a result, he got straight As on many subjects. She regarded her class as a family and they even had their own class song. She would often have them sing it to encourage them and develop a team spirit for them. When she saw that they were no longer listening carefully to what she was teaching, she would have them close their textbooks, stand up all around the room and throw around a small football. This helped them clear their minds and then focus on the lesson again. Besides, she was quick to reply to any phone calls or emails from us and got rid of our worries about children quickly.
    When my son went to the 5th grade this year, we happened to pass her classroom. When she saw my son, her face lit up(露出喜色) and she came out and hugged him. She generally loves all of the children in her classroom and that love really shows. I can only pray(祈祷) that my son will continue to get teachers just like her for the rest of his school years.

    Luo Gaoqi hopes to join the increasing number of Chinese students in the United States because he wants the experience of studying in a foreign land as it will help his future job at home. “I want to try Western education because people there think differently,” said the 21-year-old who is in his final year of undergraduate studies. “I also hope to meet friends from different cultures. The social connections may help in the future.”
    The latest report from the US-based institute of International Education said China, for the first time, has become the top country of origin for international students in the United States.
    For Yang Fan, a journalism student, said studying in the United States is a way to escape the competition for places in China’s top universities.
    “Due to limited education resources, only about 60 percent of high school graduates in China enter college, and a much lower rate enters the top-level ones. “A foreign degree will definitely help when I seek a job in China,” Yang said.
    Both Yang’s and Luo’s parents are supportive of them studying abroad. Neither of them is thinking of settling down in the United States after graduation.
    “It is not realistic to do so. As a journalism student, there would be no advantage for me to work in the United States,” Yang said. “But in China, with a US degree and good English, I may stand out against other students who have only studied in China.”
    China still needs to improve its environment for scientists and high-level talents, said Xiao Mingzheng, director of the Center for Human Resource Development and Management Research of Peking University, adding that, in particular, the country needs to improve its policies relating to research environments.
    In June, the Chinese government published a plan concerning talent development for the next 10 years. In it, it has improved policies and increased budgets to attract talented students back home.
    小题1:Why does Luo Gaoqi wants to study in a foreign land according to his words?
    A．Because the people there are more intelligent.
    B．Because the foreign countries are more developed.
    C．Because he can make more friends there.
    D．Because the culture there is different from that in China.
    小题2:What do Guo Gaoqi and Yang Fan have in common?
    A．Their major is the same, which is journalism.
    B．Both of them want to go back to China after graduation.
    C．Their parents are against their decision.
    D．They are forced to study in a foreign land by their parents.
    小题3:From the passage, we can infer that _______.
    A．scientists and high-level talents need a better environment in China
    B．the students abroad are unwilling to go back to China
    C．China doesn’t need those people to come back to our country at all
    D．we all need to go abroad to study and then serve our own country
