The science of physics today is as current as the morning newspaper. Indeed,as
a result of new advances in physics and their rapid application to inventions designed to satisfy man's wants, the world ?itself? has been changing rapidly. Space technology, industrial technology, and the technology of the home, the farm, the office, the bank, and the department store have all been revolutionized.
Clearly, every grown?up today would understand the world he lives in much better if he knew something about physics. Whether it be Congress(美國國會) voting huge sums of money for new ?warships,? space exploration, or atomic energy;the office staff learning to use a new computer;son Bobby wanting to know about going to the moon;or the housewife learning to operate a new electric stove physics seems to be everywhere.
Teachers in thousands of schoolrooms in America are trying to communicate some of the excitement and importance of these new developments to their students.
They know that some of their eager students will someday be scientists and will them selves then contribute(貢獻) to the development of new knowledge or its application to new things.
But in any case, they can be sure that if they bring a knowledge of science(any science) to their students in meaningful and stimulating ways, they have contributed much to helping each one live a more meaningful life.
1.The application of new advances in physics to inventions ________ .
A.may solve all the problems in teaching        
B.can help people understand the meaning of life        
C.is intended to meet people's needs        
D.makes people understand the voting rules of the Congress 
2.According to the passage, many American teachers are making efforts to do all of the following EXCEPT ________.
A.stimulating their students' curiosity in physics 
B.making their students understand the importance of physics 
C.giving their students the information of new advances in science 
D.creating excitement about physical education among their students   
3.The word “themselves” in the third paragraph refers to  ________ .
A.some of the eager students       B.the students in the classroom        
C.the teachers giving lessons      D.all the scientists in physics 
4.The first two paragraphs of the passage mainly tell us about ________ .
A.new advances in physics          B.the use of physics in our life        
C.the science of physics           D.modern developments in science

A study published in September suggests there is a surprising way to get people to avoid unhealthy foods: change their memories. Scientist Elizabeth Loftus of the University of California at Irvine asked volunteers to answer some questions on their personalities (個性) and food experiences. “One week later,” Loftus says, “we told those people we'd fed their answers into our smart computer and it came up with an account of their early childhood experiences.” Some accounts included one key additional detail (細節(jié)): “You got sick after eating strawberry ice-cream.” The researchers then changed this detail into a manufactured (人為促生的) memory through leading questions—Who were you with? How did you feel? By the end of the study, up to 41% of those given a false memory believed strawberry ice-cream once made them sick, and many said they'd avoid eating it.
When Loftus published her findings, she started getting calls from people begging her to make them remember hating chocolate or French fries. Unfortunately, it's not that easy. False memories appear to work only for foods you don't eat on a regular basis. But most important, it is likely that false memories can be implanted (灌輸) only in people who are unaware of the mental control. And lying to a patient is immoral, even if a doctor believes it's for the patient's benefit.
Loftus says there's nothing to stop parents from trying it with their overweight children. “I say, wake up—parents have been lying about Father Christmas for years, and nobody seems to mind. If they can prevent diseases caused by fatness and all the other problems that come with that, you might think that's a more moral lie. Decide that for yourself.”
72. Why did Loftus ask the volunteers to answer some questions?
A. To improve her computer program.           B. To find out their attitudes towards food.
C. To find out details she can make use of             D. To predict what food they'll like in the future.
73. What did Loftus find out from her research?
A. People believe what the computer tells them.
B. People can be led to believe in something false.
C. People tend to forget their childhood experiences.
D. People are not always aware of their personalities.
74. According to the study, people may stop having a certain food if they ________.
A. learn it is harmful for health                          
B. lie to themselves that they don't want it
C. are willing to let doctors control their minds
D. think they once had a bad experience of eating it
75. What is the biggest concern with the method?
A. Whether it is moral.                                B. Who it is best for.
C. When it is effective.                                D. How it should be used.

Students are being forced to take additional exams to get into leading universities because good A-levels do not always indicate the brightest candidates.
Sixth-formers applying to courses such as medicine and law are being asked to sit American-style aptitude(智能)tests, which are designed to assess(評價)thinking skills, among fears that too many A-level candidates are getting top grades. Last year, almost one in six students applying to universities such as Oxford and Cambridge from independent schools had to sit additional test to secure a place.
Head teachers criticized the move, which they said would pile more pressure on schools and students. But universities insisted that the reforms were unavoidable, because A-level exams were no longer an accurate barometer(標準)of ability.
In 1986, 40 percent of students starting at Oxford achieved straight. As at A-level, Mike Nicholson, its admissions director, said that this year almost every candidate offered a place would get perfect grades. It meant the university had to stage additional test to identify the most able candidates. “The ability to achieve three A grades is no longer the end-point in the admissions process,” he said. “The potential to achieved three A grades will allow them to enter the race for a place.”
Oxford is not the only university turning to aptitude tests. At Cambridge, the number of students taking the university’s Thinking Skills Assessment shot up 26 percent to more than 3,000. A survey of 16,830 sixth formers applying to higher education from private schools last year showed that 2,860 had to sit at least one exam.
Earlier this year, the National Foundation for Educational Research recommended that most sixth formers should sit SAT tests — a standard reasoning exam widely used in American colleges —to make it easier to pick out the best candidates.
5.What is the attitude of head teachers to the reform?
A. Approving.               B. Doubtful.          C. Opposed.           D. Neutral(中立的)
6.Which British university first started to use aptitude tests to pick out the best candidates?
A. Harvard.                  B. Oxford.             C. Cambridge.              D. Washington D.C.
7.What can we know about the A-level system?
A. It can indicate the brightest candidates.
B. It was designed to assess students’ thinking abilities.
C. It is longer an accurate way to assess students’ abilities.
D. It was recommended by the National Foundation for Educational Research.
8.What can we infer from the passage?
A. The reform is more popular in American colleges than in British ones.
B. The reform will be applied by all universities in the future.
C. Universities used to depend on the A-level system to choose the best students.
D. Passing additional tests will allow the student to enter Oxford, regardless of whether he or she gets As.
9.What is the passage mainly about?
A. How to get into leading universities.
B. The disadvantages of the A-level system.
C. Different ways to identify students’ abilities.
D. Universities using extra exams to choose students.

It's not the flashiest car in the world. Not even close. But the 1971 Volkswagen named Helioscan do something most cars can't: nm on solar energy – energy from the sun's light and heat!
Joshua Bechtold, 14, and the other students at the Riverside School in Lyndonville, Vermont, worked many months to get Helios ready for the 1999  American Tour de Sol ("Sol" is the Latin word for "sun"). They named their car after Helios, the sun god in Greek mythology(神話).
The 4-year-old Tour de Sol encourages the use of "green", or environmentally friendly, cars to help reduce pollution and save energy. It’s not a race. Cars are  judged on fuel efficiency(耗油量) rather than speed. In the week-long event, 44 cars took the 350-mile tour from Waterbury, Connecticut, to Lake George, New York. Of the 23 student cars, Helios was the only one built by middle school students.
A teacher drove Helios, but the children talked with people wherever they stopped along the mad. "That was my favorite part," says Anna Browne, 15. "We explained how the car runs.”
Due in part to old, inefficient batteries(電池), Helios finished fourth - out of four - in its kind, the sun-powered class. "We were there for the fun of it," Anna says. "We're proud of Helios," says Ariel Gleicher, 14. "It's a car that's good for the environment."
64. What is special about the car Helios in the text?       
A. It was built by middle school students.
B. It has an attractive design.
C. It was made in 1971.
D. It won the fourth prize.
65. How many sun-powered cars took part in the race?      
A. 1.       B. 4.     C. 23.    D. 44.
66. What would be the best title for the text.'?       
A. The Making of Helios
B. 1999 American Tour de Sol
C. Sun-powered Cars on the Road
D. Use of Green Cars in Connecticut
67. The students felt proud of Helios because______.
A. it could run as far as 350 miles     B. it was favored by many children
C. it had high-quality batteries         D. it was driven by clean energy

Annealing
Annealing is a way of making metal softer by heating it and then letting it cool very slowly, if metal is heated and then cooled very quickly, for example by dipping(浸) it in water, it will be very hard but also very brittle(脆)—that is, it will break easily. Metal that has been annealed is soft but does not breaks as easily. It is possible to make metal as hard or as soft as is wished, by annealing it. The metal is heated, and allowed to cool slowly for a certain length of time. The longer the heated metal takes to cool slowly, the softer it becomes. Annealing can also be used on other material, such as glass.
1. Annealing can make metal ____
  A. hard and tough(韌) B. hard but brittle  C. soft but tough  D. soft and brittle
2. Why do people put hot metal in water?
  A. To make it hard.  B. To make it soft. C. To make it cool. D. To make it brittle
3. In annealing, the required hardness of a metal depends on  ______
  A. the quantity of water used B. the temperature of the metal
  C. the softness of the metal   D. the timing of the operation
4. As suggested by the text, how can glass be made less brittle?
  A. It can be heated and then cooled quickly.
  B. It can be cooled and then heated slowly.
  C. It can be heated and then cooled slowly.
D. It can be cooled and then heated quickly.

Once in a blue moon there is one on New Year's Eve. Revelers ringing in 2010 will be treated to a so-called blue moon. According to popular definition, a blue moon is the second full moon in a month. But don't   1  it to be blue - the name has nothing to   2  the color of our closest celestial(天體) neighbor.
A full moon   3  on December 2. It will appear again on Thursday in time for the New Year's countdown.
"If you're in Times Square, you'll see the   4  moon right above you. It's going to be that brilliant," said Jack Horkheimer, director emeritus of the Miami Space Transit Planetarium and host of a weekly astronomy TV show.
The New Year's Eve blue moon will be   5  in the United States, Canada, Europe, South America and Africa. For partygoers in Australia and Asia, the full moon does not show up  6  New Year's Day, making January a blue moon month for them.
However, the Eastern Hemisphere can celebrate with a partial lunar eclipse(月蝕) on New Year's Eve when  7  of the moon enters the Earth's shadow. The   8  will not be visible in the Americas.
A full moon occurs   9  29.5 days, and most years have 12.  10 , an extra full moon in a month - a blue moon - occurs every 2.5 years. The   11  time there was a lunar double take was in May 2007. New Year's Eve blue moons are rarer, occurring every 19 years. The last time was in 1990; the next one won't  12   again until 2028.
Blue moons have no astronomical   13   , said Greg Laughlin, an astronomer at the University of California, Santa Cruz.
"`Blue moon' is just a   14  in the same sense as a `hunter's moon' or a `harvest moon,'" Laughlin said in an e-mail.
The popular definition of blue moon   15  after a writer for Sky & Telescope magazine in 1946 misunderstood the Maine Farmer's Calendar and marked a blue moon as the second full moon in a month. In fact, the calendar   16  a blue moon as the third full moon in a season with four full moons, not the usual three.
Though Sky & Telescope corrected the  17  decades later, the definition caught on. For purists(語言純正癖者), however, this New Year's Eve full moon doesn't even qualify as a   18  moon. It's just the first full moon of the winter season.
In a tongue-in-cheek essay   19  on the magazine's Web site this week, senior contributing editor Kelly Beatty wrote: "If skies are clear when I'm    20 celebrating, I'll take a peek(瞇著眼睛看) at that brilliant orb(天體) as it rises over the Boston skyline to see if it's an icy shade of blue. Or maybe I'll just howl."

B
Fear and its companion pain are two of the most useful things that man and animals possess if they are used. If fire didn’t hurt when it burned, children would play with it until their hands were burned away. Similarly, if pain existed but fear didn’t, a child could burn itself again and again because fear would not warn it to keep away from the fire that had burnt it before. A really fearless soldier—and some do exist—is not a good soldier because he is soon killed; and a dead soldier is of no use to his army. Fear and pain are therefore two guards without which man and animals might soon die out.
In our first sentence we suggested that fear ought to be properly used. If, for example, you never go out of your house because of the danger of being knocked down and killed in the street by a car, you are letting fear rule you too much. The important thing is not to let fear rule you, but instead, to use fear as your servant and guide. Fear will warn you of dangers; then you have to decide what action to take.
In many cases, you can take quick and successful action to avoid the danger. For example, you see a car coming straight towards you; fear warns you, you jump out of the way, and all is well.
In some cases, however, you decide that there is nothing that you can do to avoid the danger. For example, you cannot prevent an airplane crashing into your house, and you may not want to go and live in a desert where there are no airplanes. In this case, fear has given you its warning, you have examined it and decided on your course of action, so fear of the particular danger is no longer of any use to you, and you have to try to overcome it.
60. Children would play with fire until their hands are burnt away if _________.
A. they were not well educated at school   B. they had never played with fire before
C. they had no sense of pain             D. they were fearful of pain
61. People sometimes succeed in timely avoiding danger because _________.
A. they have gained experience     B. they are warned of the danger and take quick action
C. they jump out of the way in time  D. they are calm in face of danger
62. What is implied but not stated in the passage?
A. Too much fear is harmful              
B. Fear is always something helpful
C .Fear is something that can be avoided     
D. Fear ought to be used as our guide in our life
63.The best title for this passage should be __________.
A. No Pains, No Gains          B. Pain and Actions
C. The Value of Fear         D .The Reason Why People Fear
