Three-dimensional printers are fast becoming everyday devices in the United States. Three-D printers are used to make everything from automobile parts to bone replacements for human patients. American research scientists are now working on creating replacements for living tissue.
Researchers at the Medical University of South Carolina have been working on creating and manufacturing living tissue since 2003．This process is called biofabrication (生物制造) . It requires special printing equipment and a special kind of ink.
Traditional printers require ink to produce an image or design on a piece of paper. For their three-D printer, the South Carolina researchers prepare complex nutritious solutions they call bio-inks. Bio-inks are made of proteins and glucose (葡萄糖) , which normally provides energy for most cells of the body. The researchers also add living cells taken from the animal that will receive the new, printed tissue. The bio-inks are then added to a device that researchers call the Palmetto bio-printer.
Sarah Grace Dennis is one of the researchers at the Medical University of South Carolina. She says new technology, like the Palmetto bio-printer, is a great help to the biofabrication process.
The bio-inks are placed in three dispensers (分配器) , containers, inside the printer. Lasers control both the position of the printing surface and the places where the bio-ink is released.
Michael Yost is a leader of the research team. He says the printing process is fully automated— machine-operated. He says that the Palmetto bio-printer makes it possible to create complex tissue types.
The researchers say bio-printing is still experimental. But they hope in a few years they may be able to print tissue to replace damaged human organs.
But there are still some problems which need to be solved. Some scientists worry about how to get blood to the replacement tissue. The flow of blood is important to keep the printed tissue alive.
Michael Yost hopes that more people will believe in the benefits of biofabrication.
“Tissue biofabrication is a reality, and it is a reality now, and if you come here and you get to see it. You will get to see it. You can’t touch it, but you will see it and think this is real. And this is really human.”What can we know about the bio-inks?
| A．They are the necessities of bio-printing. |
| B．They only contain proteins and glucose. |
| C．They can be placed in the traditional printers. |
| D．They are available in our local drugstores. |
Which of the following is one of the concerns with biofabrication?
| A．Researchers can’t find enough living cells of animals to make the bio-inks. |
| B．The price of the bio-printer is too high and most people can’t afford it. |
| C．Scientists have some difficulty in getting the blood to the replacement tissue. |
| D．People are worried about the safety of the biofabrication process. |
According to Michael Yost, we can infer that .
| A．the Palmetto bio-printer can workwithout power |
| B．the Palmetto bio-printer has been used to treat the patients |
| C．the Palmetto bio-printer can only be found in the United States |
| D．the Palmetto bio-printer will have a bright future in medical use |
The passage mainly tells us about .
| A．the three-D printer and its working principles |
| B．the bio-inks and their use in bio-printing |
| C．the spread use of the bio-printer in the USA |
| D．the growing demand for biofabrication |

After the September 11 terrorist attacks, some high schools in America wanted the students to pledge allegiance（宣誓效忠） to the flag. Is it necessary or not? Let’s see how the kids think of this requirement.
Lea Mouallem, Marymount High School
I believe that saying the Pledge of Allegiance is a way of reminding our country that no matter what happens, we are united. I don’t think our president wants us to go and join the army now, but he wants to tell us that we will be able to overcome the disaster as a whole nation that is working together.
Harry Chin, 15, Culver City High School
I am not for the Pledge of Allegiance and I am not against the Pledge of Allegiance because I just say it so many times that it loses meaning. I say it every day at school in the second period. It doesn’t mean anything any more.
David Tran, 15, Warren High School.
The Pledge of Allegiance is another sign of country. We should have some respect to it. In many schools, we don’t say the Pledge every morning-we just stand up and let the National anthem ring through the silence. We said the Pledge of Allegiance on Sept. 12.
Danny Maryanor, 16, Santa Monica High School
I wonder why we were suddenly asked to recite the Pledge when many of us stopped after elementary school; and the Pledge was recited before the play of “Ode to Joy” （欢乐颂）with recorders. This was not to express patriotism（爱国主义）, or even to remember those who lost their lives on Sept. 11.
I feel I cannot support a nation that in this time of crisis looks outward for revenge（报复）instead of inward for peace. Perhaps we should think more about our problems.
68.Saying the Pledge of Allegiance to the flag first appeared in American schools______
A．after Sept. 11, 2000 B．before Sept. 11, 2001
C．on Sept. 11, 2001 D．after Sept. 11, 2001
69．Who were for the Pledge of Allegiance?
A．Lea Mouallem; David Tran B．Harry Chin; Danny Maryanor
C．Lea Mouallem; Danny Maryanor D．Harry Chin; David Tran
70．Which of the following is TRUE?
A．Harry Chin thought the government required them to join the army.
B．Lea Mouallem thought the Pledge of Allegiance of no meaning.
C．Danny Maryanor felt the terrorist attacks happened partly because of America’s own problem.
D．The Pledge of Allegiance is of another country.
71．According to the passage, it can be imagined that________.
A．all high school students say yes to the Pledge of Allegiance.
B．all high school students say no to the Pledge of Allegiance.
C．all kids don’t agree to the requirement of saying the Pledge of Allegiance.
D．all high schools will require their students to pledge allegiance to the flag.

Sports is not only physically challenging, but it can also mentally challenging. Criticism（批评）from coaches(trainers), parents, and other teammates, as well a
s pressure to win can create too much anxiety or stress for young athletes. Stress can be physical, emotional, or psychological, and research has showed that it can lead to burnout. Burnout has been described as dropping or quitting of an activity that was at one time enjoyable.
The early years of development are critical years for learning about oneself. The sport setting is one where valuable experiences can take place. Young athletes can, for example, learn how to cooperate with others, make friends, and gain other social skills that will be used throughout their live
s. Coaches and parents should be aware(realize), at all times, that their feedback（反馈）to youngsters can greatly affect their children. Youngsters many take their parents’ and coaches’ criticisms to heart and find a flaw（缺陷） in themselves.
Coaches and parents should also be cautious(careful) that youth sport participation does not become work for children. The outcome of the game should not be more important than the process of learning the sport and other life lessons. In today’s youth sport setting, young athletes may be worrying more about who will win instead of enjoying themselves and the sport. Following a game, many parents and coaches focus on(pay more attention to) the outcome and find fault with youngsters’ performances. Positive reinforcement should be provided in spite of the outcome. Research shows that positive reinforcement motivates and has a greater effect on learning than criticism. Again, criticism can create high levels of stress(pressure), which can lead to burnout.
64．According to the passage sport is positive for young people in that .
A．it can help them learn more about society
B．it teaches them how to set realistic goals for themselves
C．it enables them to find flaws in themselves
D．it can provide them with valuable experiences
65．Many coaches and parents are in the habit of criticizing young athletes .
A．without realizing criticism may destroy their self-confidence
B．in order to make them remember life’s lessons
C．believing that criticism is beneficial for their early development
D．so as to put more pressure on them
66．According to the passage parents and coaches should .
A．help children to win every game
B．pay more attention to letting children enjoy sports
C．enable children to understand the positive aspect of sports
D．train children to deal with stress
67．The author’s purpose in writing the passage is .
A．to persuade young children not to worry about criticism
B．to emphasize the importance of positive reinforcement to children
C．to discuss the skill of combing c
riticism with encouragement
D．to teach young athletes how to avoid burnout

Whatever our differences as human beings are, we all think we’re more like the rest of the animal world than we realize. It is said that we share 40 per cent of our genetic（遗传的）structure with the simple worm.
But that fact has helped Sir John Sulston win the 2002 Nobel Prize for Medicine. Sir John is the founder of the Sanger Institute in Cambridge, which was set up in 1992 to get further understanding of the human genome（染色体组.
To help them do this, they turned to the worm. The nematode（线虫类的）worm is one of the earliest creatures on planet earth. It is less than one millimeter long, completely transparent and spends its entire life digging holes through sand. But it still has lots to say about human life, and what can be done to make it better.
What the worm told Sir John and his colleagues was that each of cells in the human body is programmed like a computer. They grow, develop and die according to a set of instructions that are coded in our genetic make-up.
Many of the diseases that humans suffer from happen when these instructions go wrong or are
not obeyed. When the cell refuses to die but carries on growing instead, this leads to cancer. Heart attacks and diseases like AIDS cause more cell deaths than normal, increasing the damage they do to the body. Sir John was the first scientist to prove the existence of programmed cell death.
60．Sir John Sulston got a Nobel Prize for Medicine because he has .
A．found that human beings are similar to the worn
B．got the fact we share 40 per cent of our genetic structure with the simple worm
C．found the computer which controls each of the cells in the human body
D．proved that cell death is programmed
61．People might be seriously ill if the cells in heir body .
A．grow without being instructed B．die regularly
C．fail to follow people’s instructions D．develop in the human body
62．The underlined word “they” (paragraph 5) refers to .
A．cell deaths B．diseases C．instructions D．cells
63．What is the subject discussed in the text?
A．The theory of programmed cell deaths.
B．A great scientist—Sir John Sulston.
C．The programmed human life.
D．Dangerous diseases.
第三部分:阅读理解(共20小题,每小题2分,满分40分
)
阅读下列短文,从每题所给的四个选项（A、B、C和D）中,选出最佳选项。
A
A lot of management training each year for Circle K Corporation, a national chain of convenience stores. Among the topics we address in our course is the retention（保护力） of quality employees-a real challenge to managers when you consider the pay scale（标准）in the service industry. During these discussions, I ask the participants（参加者）, “What has caused you to stay long enough to become a manager?” Some time back a new manager took the question and slowly, with her voice almost breaking, said, “It was a ＄19 baseball glove.”
Cynthia told the group that she originally took a Circle K clerk job as an interim（临时的） position while she looked for something better. On her second or third day behind the counter, she received a phone call from her nine-year-old son, Jessie. He needed a baseball glove for Little League. She explained that as a single mother, money was very tight, and her first check would have to go for paying bills. 
Perhaps she could buy his baseball glove with her second or third check. When Cynthia arrived for work the next morning, Patricia, the store manager, asked her to come to the small room in the back of the store t
hat served as an office. Cynthia wondered if she had done something wrong or left some part of her job incomplete from the 
day before. She was concerned and confused.
Patricia handed her a box. “I overheard you talking to your son yesterday,” she said, “and I know that it is hard to explain things to kids. This is a baseball glove for Jessie because he may not understand how important he is, even though you have to pay bills before you can buy gloves. You know we can’t pay good people like you as much as we would like to; but we do care, and I want you to know you are important to us.”
The thoughtfulness, empathy and love of this convenience store manager demonstrates vividly that people remember more how much an employer cares than how much the employer pays. An important lesson for the price of a Little League baseball glove.
56．Among many of the problems in the service industry, what is talked about in this passage, is___
A．how to ensure his employees’ high pay

57．Although a new manager, Cynthia would do her job well in keeping quality employees because she________.
A．had mastered all the courses for the manager
B．had already formed good relationship with the employees
C．know the way how to deal with her employees
D．had her own personal experience
58．This passage shows us that to run a business well it is necessary for managers to let their employees know________
A．how much they can get for their job.
B．what good positions they can get later
C．they are very necessary to the business
D．they are nice as well as useful
59.The story told in this passage tells us that employees care about____________
A．only how large a pay they can get
B．love from the managing people rather than only money
C．if their children could be properly taken care of
D．what position they can be offered
二．根据各小题的具体要求，简要回答问题
Scientists identify “ Happiness Gene ”
If life looks joyful in spite of recession (经济衰退) ，job insecurity and expanding waistline, then you should consider thanking your “brightside ” gene.
A gene that affects if we’re cheery or gloomy has been tracked down by British researchers, reports The Guardian.
The groundbreaking study claims that individuals who carry the gene don’t pay much attention to negative things happening in their lives and, instead, focus on the happier aspects of life. In the process, they end up becoming more sociable and are generally in better shape psychologically.
Elaine Fox, head of psychology at Essex University, said: “ We’ve shown for the first time that a genetic variation is linked with a tendency to look on the bright side of life. This is a key mechanism underlying resilience (复原力) to general life stress. ”
To reach the conclusion, the research team checked how long it took people to react to good and bad images that flashed up on a computer screen. The study involved more than 100 volunteers.
The positive snaps were that of a couple hugging and someone sailing along in a boat. The negative images included a photo of someone being mugged(抢劫).
Every individual inherits(继承) two versions of the gene, either two short ones, two long ones , or one of each. People who had two long versions were most likely to focus on the positives, according to the study published in Proceedings of the Royal Society B(《皇家学会学报B》) .
