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 (災(zāi)難性的) 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.

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(投資) 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.
小題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
小題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
小題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

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．

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(涌現(xiàn))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．”
小題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．
小題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．
小題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
小題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(課程)around their individual needs.” They will “l(fā)earn 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.
小題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
小題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
小題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
小題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.
