    Until recently, the "science of the future" was supposed to be electronics and artificial intelligence. Today it seems more and more likely that the next great breakthroughs in technology will be brought through a combination of those two sciences with organic chemistry and genetic engineering. This combination is the science of biotechnology.
    Organic chemistry enables us to produce marvelous synthetic materials. However, it is still difficult to manufacture anything that has the capacity of wool to conserve (保存) heat and also to absorb moisture. Nothing that we have been able to produce so far comes anywhere near the combination of strength, lightness and flexibility that we find in the bodies of ordinary insects.
    Nevertheless, scientists in the laboratory have already succeeded in "growing" a material that has many of the characteristics of human skin. The next step may well be "biotech hearts and eyes" which can replace diseased organs in human beings. These will not be rejected by the body, as is the case with organs from humans.
    The application of biotechnology to energy production seems even more promising. In 1996 the famous science fiction writer, Arthur C. Clarke, many of whose previous predictions have come true, said that we may soon be able to develop remarkably cheap and renewable sources of energy. Some of these power sources will be biological. Clarke and others have warned us repeatedly that sooner or later we will have to give up our dependence on non-renewable power sources. Coal, oil and gas are indeed convenient. However, using them also means creating dangerously high levels of pollution. It will be impossible to meet the growing demand for energy without increasing that pollution to catastrophic (灾难性的) levels unless we develop power sources that are both cheaper and cleaner.
    It is attempting to think that biotechnology or some other "science of the future" can solve our problems. Before we surrender to that temptation we should remember nuclear power. Only a few generations ago it seemed to promise limitless, cheap and safe energy. Today those promises lie buried in a concrete grave in a place called Chernobyl, in the Ukraine. Biotechnology is unlikely, however, to break its promises in quite the same or such a dangerous way.
    小题1:According to the passage, the science of the future is likely to be ________.
    A．electronicsB．biotechnology
    C．genetic engineeringD．nuclear technology
    小题2:The materials produced with organic chemistry are ________.at present.

    A．to transplant human organs
    B．to make artificial hearts and eyes
    C．to produce drugs without side effects
    D．to make something as good as human skin
    小题4:In 1996, Arthur C. Clarke predicted that_______.
    A. the Chernobyl disaster would happen in two years
    B. we will never stop using non-renewable power sources biological  
    C. oil, gas and coal could be repeatedly used in the future
    D. power sources would be put into use soon
    小题5:What do we learn from the last paragraph?
    A．Biological power will keep all its promises.
    B．Biological power is cheaper than nuclear power.
    C．Biotechnology can solve all our future energy problems
    D．Biological power may not be as dangerous as nuclear power

    试题分析：文章大意：明天的科学将是有机化学和遗传工程学的结合，这就是生物科技。虽然目前有机化学生产的材料不如天然材料那么好，但是生物科技不会像原子能那样对人类有害。本文就讲了生物科技对人类的好处。
    小题1:B细节理解题。根据第一段…combination of those two sciences with organic chemistry and genetic engineering. This combination is the science of biotechnology.很容易找出答案，明天的科技可能就是生物科技。所以答案选B。
    小题2:D 细节理解题。 根据第二段it is still difficult to manufacture anything that has the capacity of wool to conserve (保存) heat and also to absorb moisture.可知，目前来说有机化学生产的材料不如羊毛保温吸潮。也就是说不如天然材料好。所以正确答案为D。
    小题3:B 细节理解题。根据第三段The next step may well be "biotech hearts and eyes" which can replace diseased organs in human beings.可知，生物科技很可能制造出人工的心脏和眼睛来替代人身上患病的器官。所以答案选B。
    小题4:D 细节理解题。根据第四段…said that we may soon be able to develop remarkably cheap and renewable sources of energy. Some of these power sources will be biological.可知，1996年Arthur C. Clarke就预言，我们很快就能生产出既便宜又可再生的能源…所以答案选D。
    小题5:D 细节理解题。…nuclear power…Biotechnology is unlikely, however, to break its promises in quite the same or such a dangerous way.可知，生物科技不会像原子能科技那样对人类有危害。所以答案选D。

    California, once regarded as a leader in the United States for its public higher education system, ranks next to the last in the U.S.for its number of adults with at least a high school diploma, according to the report, titled “California at the Edge of a Cliff,” released by the California Faculty Association.
    Meanwhile, the state’s investment(投资) in public higher education has dropped over the past three decades, and now ranks 22nd in the country.That’s despite having the country’s largest public higher education system, the report said.
    “It's a collapse(衰退),” said Thomas Mortenson, author of the report, who is an independent analyst living in Iowa and a senior scholar at the Pell Institute for the Study of Opportunity in Higher Education in Washington, D. C. “Ranking 49th out of 50 states is an indication that shows the quality of the state’s educational has become much worse in recent decades.” Mortenson said in the report.As of 2007, California ranked 14th in the United States in terms of college educated members of the workforce over 25 years of age, a drop from eighth place in 1981, the report showed.
    Mortenson said that California has never been the state of high status in education and economy while other states have made greater gains in building a college-educated workforce.
    The California Faculty Association is using the report’s findings to criticize Governor Arnold Schwarzenegger’s proposed funding cuts for education.
    Struggling with a 14.8-billion-dollar state budget deficit(赤字), Schwarzenegger has proposed a combination of sales tax increases, borrowing and major budget cuts, including cutting billions of dollars from the state’s education budget.
    小题1:The passage is mainly about __________.
    A．California’s worse situation in higher education
    B．the dangerous situation in California
    C．California’s research on education and economy
    D．funding cuts for high education in California
    小题2:From the passage we can infer that __________.
    A．investment in higher education has dropped in all states
    B．Thomas Mortenson works at California Faculty Association
    C．governor in California agreed to spend more money on education
    D．California had higher quality in higher education in the past
    小题3:The reason why California has a lower rank in education is that________.
    A．the number of adults has decreased recently
    B．the result of report has been published late
    C．the money to invest in education has been cut
    D．the progress in other states has been made
    小题4:According to the report’s findings, ________ is to blame for the drop in rank of education.
    A．Arnold SchwarzeneggerB．Thomas Mortenson
    C．the Pell InstituteD．California Faculty Association
    语篇解读 曾经在大学教育排行榜上位居第一的美国加州，现在的教育排名一下子跌落到倒数第二。这是怎么回事呢？

    All parents know that one of their most important tasks is to prepare their children for an independent life，but any parent can tell you that it’s hard to let go of your children．That balance between keeping your children safe and allowing them to learn from their own mistakes can be heartbreaking．Years of experience means that parents often do know best，but on the other hand，the young，being less bound by tradition，are often more creative，more able to find new solutions to old problems．Revolutions are led by the young．
    Good teachers make the growth of critical （批判性的） thinking easier in their students，only to find that this can lead to a questioning of the teachers’ basic beliefs．Schools encourage parents to become involved，but are often embarrassed when parents have reservations about some of the educational methods being used．Governments encourage unimportant groups to empower themselves in order to participate fully in the development process．And they are often surprised when the new leaders of these groups turn around and attack the policies of that same government．The rebellions （叛逆的）young and the newly unimportant groups are important in social development．They are not necessarily representatives of those they want to represent or not realistic in their demands，but their voices must be heard．
    Good parents know that just forbidding particular behaviors does not prevent their children from finding ways to engage in these forbidden activities．Indeed，sometimes the forbidden fruit is more inviting，just because it is not accepted by authority．Parents must work with their children to educate them on the facts，know as much as possible about he lives of their children，provide a good example，encourage more wholesome activities but also support their children when they don’t follow what is expected of them．But the most important point is that they also need to learn how to let go．
    小题1:By saying “Revolutions are led by the young”，the author indicates that young people are more___________________．
    A．conventionalB．creative
    C．realisticD．heartbreaking
    小题2:From the second paragraph we know__________________．
    A．the voice of the rebellious young should be heard by the government
    B．schools encourage parents to question their education methods
    C．movement is satisfied with the new leaders’ attack on the policies
    D．teachers’ basic beliefs should be questioned by students
    小题3:In order to educate children well，parents should_________________．
    A．forbid particular behaviors in their daily life
    B．know as much as possible as their children
    C．educate them with facts and expect much of them
    D．know them well and set a good example to them
    小题4:From the passage we can learn that the author prefers ___________________．
    A．free parentingB．traditional parenting
    C．smart parentingD．critical parenting
    小题5:What is the best title of the passage?
    A．Teaching Methods – for Teachers and Schools

    Coffee is a powerful beverage．On a personal level，it helps keep US awake and active．On a much broader level，it has helped shape our history and continues to shape our culture．
    Coffee didn’t take off until the l400s when people figured out they could roast its seeds．By the l500s，the drink had spread to coffeehouses across the Arab world．Within another l50 years，it took Europe by storm．
    “It actually had a major impact on the rise of business，” historian Mark Pendergrast says．Coffeehouses became a spot not just to enjoy a cup but to exchange ideas．The insurer Lloyd’s of London was founded hundreds of years ago in one of London’s 2,000 coffeehouses．Literature，newspapers and even the works of great composers like Bach and Beethoven were also spawned(涌现)in coffeehouses．
    It is often said that after the Boston Tea Party of l773，when American colonists attacked British tea ships and threw boxes of tea into the harbor，Americans universally switched over to drinking coffee．In a letter John Adams wrote to his wife，Abigail，the Founding Father claims his love of tea but says he will have to learn to embrace coffee instead，because drinking tea had become a symbol of not loving the country．
    For all the upsides coffee has brought the modern world，it also led to its fair share of downsides，too．Europeans carried coffee with them as they colonized various parts of the world，and this frequently meant they enslaved people in order to grow it．In Brazil — where slavery was legal until l888 — coffee plantations would use slash-and-burn agriculture，tearing down rain forests and planting coffee trees．Once the soil had been exhausted，growers would move on to another place．
    And yet，coffee，as Pendergrast says，”had a very good impact in many ways on our civilization，even though it was，for a long time，grown by slaves．”
    小题1:Why did people enjoy going to coffeehouses?
    A．Because it was a fashion to drink coffee．
    B．Because coffeehouses provided a better flavor．
    C．Because they could stay awake and active there．
    D．Because they could exchange ideas there．
    小题2:What can we learn from the fourth paragraph?
    A．American colonists made great profits by trading in coffee．
    B．Tea was regarded as a symbol of loving one’s country．
    C．Coffee became very popular after the incident in Boston．
    D．John Adams was the Founding Father of the Tea Party．
    小题3:In the fifth paragraph．the writer points out that __________ .
    A．Coffee plantation was closely connected with slavery
    B．coffee plantation led to outdated agriculture in Brazil
    C．slavery in Brazil had been against the law until l888
    D．slavery was responsible for the damage to rainforests
    小题4:What is mainly talked about in this passage?
    A．Some interesting stories about coffee culture．
    B．Important Roles that coffee played in history．
    C．How coffee became the most popular beverage．
    D．How coffee affected America’s independence．

      How would you like to teach yourself, rather than have teachers? According to the UK’s Department of Education and Skills, students will teach themselves in the schools of the future. This means that there will be no more problems such as finding enough teachers.
    Estelle Morris, the UK Education Secretary, opened the 2002 Education Technology Conference in London recently. To start the conference, she presented a video showing a computer—generated model of the school of tomorrow.
    Greater use of computer technology and classroom assistants will help students develop their own way of learning, Morris said. She added that this is a more exciting as well as a more interesting way of learning.
    At the same time, teachers will be “freed from their traditional role as the source of all knowledge”.
    Children of all abilities will “form the curriculum(课程)around their individual needs.” They will “learn in their own time, at their own speed and in their own environment”.
    At home or at school, they will follow their learning programmes by looking at online libraries and watching lessons by world-class teachers and subject experts.
    Instead of going on field trips, students will use virtual reality. If they don’t understand something, they can ask other students—“take part in virtual communities with learners with similar needs”—or e-mail their teachers. They will hand in their work electronically to be “auto-marked”.
    The classroom of the future is fast becoming a reality.
    And the Department of Education will soon produce a guide to help schools adapt buildings for new technology, Morris said. These ideas are based on the UK government’s plan to create an education system that provides students with a strong grounding of knowledge and skills at primary school level. And provides the chance for students to develop their individual skills at secondary school level.
    小题1:According to the UK’s Department of Education and Skills, the school of the future will ______.
    A．cause more problems such as being able to find enough teachers
    B．set no homework and no tests for students
    C．make good use of the computer technology and classroom assistants
    D．enable students to learn by themselves without teachers
    小题2:Estelle Morris thinks that computer technology does good to teachers in ________.
    A．helping students develop their own way of learning
    B．enabling students to experience interesting and exciting ways of learning
    C．providing students with knowledge of all sorts
    D．not being considered the source of various knowledge
    小题3: If the students do not understand something, they can _______.
    A．go on a field trip
    B．go to ask their teachers to help them
    C．send e-mail to ask for a teacher’s help
    D．have a look at other learners’ homework
    小题4: If s a student is under the UK’s newly-developed education system,he will be ________.
    A．provided with a basic knowledge from the beginning
    B．given more knowledge at primary school level
    C．helped to use computers better
    D．supplied chance to develop their basic skills

    A wave of recent research has pointed to the risks of over praising a child. And it seems that how to draw a line between too little praise and too much has become a high-pressure _  _act for parents.
    Self-esteem (自尊)  serves as a kind of tool to measure how much children feel valued and accepted by     . This sensitivity to others'      develops because of humans' need for social acceptance, which is considered to be      to survival. As early as age 8, children's self-esteem tends to rise and fall in response to feedbacks about      peers see them as likable or attractive.     , it can also be beneficial for kids to feel bad about themselves occasionally, if they behave in selfish, mean or hurtful ways that might      their ability to maintain relationships or hold a job in the future.
    In the past, many parents and educators believed that high self-esteem      happiness and success, and kids could gain self-esteem simply by getting      and awards from their parents, teachers and people around. But recently researchers have found self-esteem doesn't  _   these desired results. Instead, if parents praise their kids     , their self-esteem becomes focused on being very smart and being the best and being perfect. Building too much self-esteem of the children can not go as planned, making them feel      later on when they hit setbacks (挫折).
    According to some experts, it can actually be good for kids to have      self-esteem, at least once in a while. And praise can be      if it disregards the world outside the home. Children who have a      understanding of how they are seen by others tend to get recovered more readily      disappointment, depression or the like. The best path is a      road, helping children develop a positive but      view of themselves in relation to others by praising them for the      they invest and behaviors they are able to sustain, like "It's      that you're working so hard on your homework. "
