Today a student cannot master knowledge, he can only be its servant. He knows that he can become familiar (熟悉) with only a small comer of knowledge and that his learning will always be imperfect and imcomplete. But he can still hope to add something to the sum(总量) of knowledge, and so make the situation slightly more difficult for those who come after him.

C．in 50 years of the 20th century
D．in 1950--2000
听力原文： Men and women in the United States who want to become doctors usually attend four years of college or university; next they study for four years in a medical school. After that they work in hospitals as medical residents or doctors in training for one to five years. Some people study and work for as many as 13 years before they begin their lives as doctors.
During their university years, people who want to become doctors study science intensively. They must study biology, chemistry and other sciences. If they do not, they may have to return to college for more education in science before trying to enter medical school.
T here are 125 medical schools in the United States. It is difficult to gain entrance to them. Those who do the best in their studies have a greater chance of entering medical school. Each student also must pass a national examination to enter a medical school. Those who get top scores have the best chance of being accepted. Most people who want to study medicine seek to enter a number of medical schools. This increases their chances of being accepted by one. In 1999, almost 47,000 people competed for about 17,000 openings in medical schools.

For thousands of years, people have known that the best way to understand a concept is to explain it to someone else. "While we teach, we learn," said Roman philosopher Seneca. Now scientists are bringing this ancient wisdom up-to-date. They're documenting why teaching is such a fruitful way to learn, and designing innovative ways for young people to engage in instruction. Researchers have found that students who sign up to tutor others work harder to understand the material, recall it more accurately and apply it more effectively. Student teachers score higher on tests than pupils who're learning only for their own sake. But how can children, still learning themselves, teach others？ One answer: They can tutor younger kids. Some studies have found that first-born children are more intelligent than their later-born siblings (兄弟姐妹). This suggests their higher IQs result from the time they spend teaching their siblings. Now educators are experimenting with ways to apply this model to academic subjects. They engage college undergraduates to teach computer science to high school students, who in turn instruct middle school students on the topic. But the most cutting-edge tool under development is the "teachable agent"—a computerized character who learns, tries, makes mistakes and asks questions just like a real-world pupil. Computer scientists have created an animated (动画的) figure called Betty's Brain, who has been "taught" about environmental science by hundreds of middle school students. Student teachers are motivated to help Betty master certain materials. While preparing to teach, they organize their knowledge and improve their own understanding. And as they explain the information to it, they identify problems in their own thinking. Feedback from the teachable agents further enhances the tutors' learning. The agents' questions compel student tutors to think and explain the materials in different ways, and watching the agent solve problems allows them to see their knowledge put into action. Above all, it's the emotions one experiences in teaching that facilitate learning. Student tutors feel upset when their teachable agents fail, but happy when these virtual pupils succeed as they derive pride and satisfaction from someone else's accomplishment. 1. What are researchers rediscovering through their studies？ A.Seneca's thinking is still applicable today. B.Better learners will become better teachers. C.Human intelligence tends to grow with age. D.Philosophical thinking improves instruction.

Paradoxes of this kind arise when the time traveler tries to change the past, which is obviously impossible. But that does not prevent someone from being a part of the past.
Suppose the time traveler goes back and rescues a young girl from murder, and this girls grows up to become his mother. The causal loop is now self-consistent and no longer paradoxical. Causal consistency might impose restrictions on what a time traveler is able to do, but it does not rule out time travel per second.
Even if time travel isn't strictly paradoxical, it is certainly weird. Consider the time traveler who leaps ahead a year and reads about a new mathematical theorem in a future edition of Scientific American. He notes the details, returns to his own time and teaches the theorem to a student, who then writes it up for Scientific American. The article is, of course, the very one that the time traveler reads. The question then arises: Where did the information about the theorem come from？ Not from the time traveler, because he read it, but not from the student either, who learned it from the time traveler. The information seemingly came into existence from nowhere, reasonlessly.
The bizarre consequences of time travel have led some scientists to reject the notion outright. Stephen W. Hawking of the University of Cambridge has proposed a "Chronology protection conjecture," which would outlaw causal loops. Because the theory of relativity is known to permit causal loops, chronology protection would require some other factors to intercede to prevent travel into the past. What might this factor be？ One suggestion is that quantum processes will come to the rescue. The existence of a time machine would allow particles to loop into their own past. Calculations hint that the ensuring disturbance would become self-reinforcing, creating a runaway surge of energy that would wreck the wormhole.
The first paragraph intends to show ______.
A．the time machine in the future would be feasible
B．the time machine in the future is just like the Pandora's ox
C．the time machine in the future is still doubtful
D．the time machine in the future might cause murder
How Should Teachers Be Rewarded？
We never forget our best teachers-those who inspired us with a deeper understanding or an enduring passion, the ones we come back to visit years after graduating, the educators who opened doors and altered the course of our lives.
It would be wonderful if we knew more about such talented teachers and how to multiply their number. How do they come by their craft？ What qualities and capacities do they possess？ Can these abilities be measured？ Can they be taught？ Perhaps above all:How should excellent teaching be rewarded so that the best teachers--the most competent, caring and compelling--remain in a profession known for low pay and low status？
Such questions have become critical to the future of public education in the U.S. Even as politicians push to hold schools and their faculty members responsible as never before for student learning, the nation faces a shortage of teaching talent. About 3.2 million people teach in U.S. public schools, but, according to an estimate made by economist William Hussar at the National Center for Education Statistics, the nation will need to recruit an additional 2.8 million over the next eight years owing to baby-boomer retirement, growing student enrollment and staff turnover (人员调整)--which is especially rapid among new teachers. Finding and keeping high-quality teachers are key to America's competitiveness as a nation. Recent test results show that U.S. 10th-graders ranked just 17th in science among peers from 30 nations, while in math they placed in the bottom five. Research suggests that a good teacher is the single most important factor in boosting achievement, more important than class size, the dollars spent per student or the quality of textbooks and materials.
Across the country, hundreds of school districts are experimenting with new ways to attract, reward and keep good teachers. Many of these efforts borrow ideas from business. They include signing bonuses for hard-to-fill jobs like teaching high school chemistry, housing allowances and what might be called combat pay for teachers who commit to working in the most distressed schools. But the idea gaining the most motivation--and controversy--is merit pay, which attempts to measure the quality of teachers' work and pay teachers accordingly.
Traditionally, public-school salaries are based on years spent on the job and college credits earned, a system favored by unions because it treats all teachers equally. Of course, everyone knows that not all teachers are equal. Just witness how hard parents try to get their kids into the best classrooms. And yet there is no universally accepted way to measure competence, much less the great charm of a truly brilliant educator. In its absence, policy-makers have focused on that current measure of all things educational: student test scores. In districts across the country, administrators are devising systems that track student scores back to the teachers who taught them in an attempt to assign credit and blame and, in some cases, target help to teachers who need it. Offering bonuses to teachers who raise student achievement, the theory goes, will improve the overall quality of instruction, retain those who get the job done and attract more highly qualified candidates to the profession--all while lifting those all-important test scores.
Such efforts have been encouraged by the Bush Administration, which in 2006 started a program that awards $99 million a year in grants to districts that link teacher compensation to raising student test scores. Merit pay has also become part of the debate in Congress over how to improve the 2001 No Child Left Behind Act. Last summer, Barack Obama signed merit pay at a meeting of the National Education Association, the nation's largest teachers' union, so long as the measure of merit is "developed with teachers, not imposed on them and not based on

What is "computer literacy"？ The term itself seems to imply some degree of" knowing" about computers, but knowing what？ The present opinion seems to be that this should include a general knowledge of what computers are, plus a little of their history and something of how they operate.
Therefore, it is important that educators everywhere take a careful look not only at what is being done, but also at what should be done in the field of computer education. Today most adults are able to use a motor car without the slightest knowledge of how the internalcombustion engine (内燃机) works. We effectively use all types of electrical equipment without being able to tell their histories or to explain how they work.
Business people for years have made good use of typewriters and adding machines, yet few have ever known how to repair them. Why, then, attempt to teach computers by teaching how or why they work？
Rather, we first must fix our mind on teaching the effective use of the computer as the tool is.
"Knowing how to use a computer is what's going to be important. We don't talk about 'auto- mobile literacy'. We just get in our cars and drive them."
The underlined part "print illiterate" in the text refers to ______.
A．one who has never learnt printing
B．one who has never learnt to read
C．one who is not computer literate
D．one who is not able to use a typewriter
World English may be entered at any one of three different levels. The First Level, Books One and Two, is intended for students with little or no education in English. Books Three and Four make up the Second Level; they are suitable for students who have some knowledge of English. The Third Level, Books Five and Six, is intended for students who are concerned with improvement.
World English teaches four basic skills of language: listening, speaking, reading, and writing. At all levels, each skill is presented systematically. In the First Level, listening and speaking receive more attention. In the latter books, reading and writing become more important. However, reading and writing activities are presented even in Unit One of Book One; and listening and speaking exercises occur from Unit One of Book One to Unite Ten of Book Six.
This passage is probably taken from the______ of an English textbook.
A．contents
B．introduction
C．first chapter
D．index (索引)
Kelley's students have been writing to celebrities from across the nation asking for a photo and a few words of advice. "It really takes a lot of time and money," Kelley said. First, Kelley and his students make a list of all the celebrities to whom they want to write. Once a student picks a star, Kelley looks them up in his book of addresses to see if he can write to that person.
Writing to the stars takes a lot of time because he has to personalize each letter, print them out, and address them. In the letter, Kelley asks the celebrity to send his classes a picture with some advice he or she would give to today's youth.
Kelley takes up a collection in all of his classes and asks each student to contribute (捐) ft dollar to pay for the postage. Once Kelley mails off all the letters, the fun really begins. So far he has gotten back about 20 letters and pictures. "The only thing that isn't cool is when the celebrity sends the picture back with no advice on it, which is my entire purpose in doing this," said Kelley. When he gets at least three pictures returned, he lets his classes guess who the three stars are. He keeps score of how many celebrities each class has guessed. Jason Bryant, a student, said, "It's become a contest(竞赛) between the classes to see who can guess the most stars, and it's really fun."
What is the text about？
A．Celebrities sending photos to Kelley.
B．Celebrities giving advice to students.
C．Kelley and his classes writing to celebrities.
D．Kelley inviting celebrities to his classes.
