Some people can stay up all night and still get work done the next day. I’m not one of them. After a night without enough sleep, I feel sleepy. I have trouble remembering things. And all I want to do is to go back to bed and sleep.
How do you feel after you’ve stayed up late to finish schoolwork? Or the day after a slumber(睡眠) party? Scientists now say that your answers to these questions may depend on your genes, which tell our bodies and brains what to do. People have about 40,000 genes, and each gene can have different forms.
A new research suggests that a gene called period3 affects how well you function without sleep. The discovery adds to older evidence that period3 helps determine whether you like to stay up late or get up early.
The period3 gene comes in two forms: short and long. Everyone has two copies of the gene. So, you may have two longs, two shorts, or one of each. Your particular combination depends on what your parents passed on to you.
Scientists studied 24 people who had to stay awake for 40 hours straight. Then they took tests that measured how well they could remember lists of numbers.
Results showed that the people with the short form of period3 performed much better than those with the long form did. In both groups, people performed worst in the early morning. After the first round of experiments, participants were finally allowed to sleep. People in the group that performed well on the tests took about 18 minutes to nod off(瞌睡).
People with long period3 gene fell asleep in just 8 minutes. They also spent more time on deep sleep. That suggests that people with the long form of the gene need more and deeper sleep to keep their brains working in top form.
I think I must have the long form period3. What about you?

A. the size of your brain         B. the kind of genes you have
C. your health                 D. your will

The dog that gave us the most trouble was a beagle (猎兔犬) named Murphy．As far as I’m concerned, the first thing he did wrong was to turn into a beagle．I had seen him bounding around on the other side of a pet-shop window, and I went in and asked the man, “How much is that adorable fox terrier (小猎狗) in the window?” Did he say “That adorable fox terrier is a beagle”? No, he said, “Ten dollars, lady.” Now, I don’t mean to say one word against beagles．They have rights just like other people．But it is a bit of a shock when you bring home a small ball of fluff (绒毛) in a shoebox, and three weeks later it’s as long as the sofa．
Murphy was the first dog I ever trained personally, and I was delighted at the enthusiasm with which he took to the newspaper．It was some time later that we discovered, to our horror, that—like so many dogs—he had grasped the letter but not the spirit of the thing．Until the very end of his days he felt a real sense of duty whenever he saw a newspaper—any newspaper—and it didn’t matter where it was．I can’t bring myself to go into the details, except to mention that we were finally forced to keep all the papers in the bottom of the icebox．
He had another habit that used to leave us open to a certain amount of criticism from our friends．He never climbed up on beds or chairs or sofas．But he always sat on top of the piano．In the beginning we used to try to pull him off．But after a few noisy fights in which he knocked a picture off the wall, scratched the piano, and smashed a lamp, we just gave in—only to discover that he hopped up and down as skillfully as a ballet dancer．
Nowadays if I go anywhere, I just ask if they have a dog．If they do, I say, “Maybe I’d better keep away from it—I have bad allergy.” This sometimes annoys the host．But it works．It really works.
56．The writer uses a hyperbole (夸张) in Paragraph 1 to suggest that the dog grew _____________.
A．surprisingly lovable B．comfortable in the house
C．too fierce to tolerate D．larger than expected
57．Which sentence shows the author’s inability to train Murphy?
A．I had seen him bounding around on the other side of a pet-shop window.
B．We were finally forced to keep all the papers in the bottom of the icebox.
C．He never climbed up on beds or chairs.
D．Nowadays if I go anywhere, I just ask if they have a dog．
58．What can you infer from the second paragraph?
A．The writer tried to train Murphy to fetch newspapers but in vain.
B．Like other dogs, Murphy hated newspapers.
C．Murphy learned to help the writer clean the papers.
D．Murphy liked fetching letters rather than newspapers.
59．Which can be the best title of the passage?
A．Murphy—My Favorite Dog B．Murphy—An Adorable Dog
C．Murphy Gave Me Trouble D．Murphy Turned Into A Beagle

Sport is not only physically challenging，but it can also be mentally challenging. Criticism from coaches，parents，and other teammates，as well as pressure to win can create an excessive amount of anxiety or stress for young athletes. Stress can be physical，emotional，or psychological，and research has indicated 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 lives. Coaches and parents should be aware，at all times，that their feedback to youngsters can greatly affect their children. Youngsters may take their parents’ and coaches’ criticisms to heart and find flaws（缺陷）in themselves.
Coaches and parents should also be cautious 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 the outcome and find fault with youngsters’ performances. Positive reinforcement（正面强化）should be provided regardless of the outcome. Research indicates that positive reinforcement motivates and has a greater effect on learning than criticism. Again，criticism can create high levels of stress, which can lead to burnout.
72．An effective way to prevent the burnout of young athletes is ____________.
A．to make sports less competitive
B．to make sports more challenging
C．to reduce their mental stress
D．to increase their sense of success
73．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 experience
74．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 lessons
C．believing that criticism is beneficial for their early development
D．so as to put more pressure on them
75．The author’s purpose in writing the passage is ____________.
A．to persuade athletes not to worry about criticism
B．to emphasize the importance of positive reinforcement to young athletes
C．to discuss the skill of combining criticism with encouragement
D．to teach young athletes how to avoid burnout

Susan Sontag（1933—2004） was one of the most noticeable figures in the world of literature. For more than 40 years she made it morally necessary to know everything—to read every book worth reading, to see every movie worth seeing. When she was still in her early 30s，publishing essays in such important magazines as Partisan Review，she appeared as the symbol of American culture life，trying hard to follow every new development in literature，film and art. With great effort and serious judgment，Sontag walked at the latest edges of world culture.
　　Seriousness was one of Sontag’s lifelong watchwords（格言），but at a time when the barriers between the well-educated and the poor-educated were obvious, she argued for a true openness to the pleasure of pop culture. In “Notes Camp”, the 1964 essay that first made her name，she explained what was then a little—known set of difficult understandings，through which she could not have been more famous.“Notes on Camp”，she wrote，represents “a victory of ‘form’ over ‘content’, ‘beauty’ over ‘morals’ ”.
By conviction（信念）she was a sensualist（感觉论者），but by nature she was a moralist（伦理学者），and in the works she published in the 1970s and 1980s，it was the latter side of her that came forward. In “Illness as Metaphor”—published in 1978，after she suffered cancer—she argued against the idea that cancer was somehow a special problem of repressed personalities（被压抑的性格），a concept that effectively blamed the victim for the disease. In fact，re-examining old positions was her lifelong habit.
In America，her story of a 19th century Polish actress who set up a perfect society in California，won the National Book Award in 2000. But it was as a tireless，all-purpose cultural view that she made her lasting fame.
“Sometimes,” she once said，“I feel that，in the end，all I am really defending…is the idea of seriousness，of true seriousness.”And in the end，she made us take it seriously too.
64．The underlined sentence in paragraph l means Sontag ____________.
A．was a symbol of American cultural life
B．developed world literature，film and art
C．published many essays about world culture
D．kept pace with the newest development of world culture
65．She first won her name through____________.

B．her book Illness as Metaphor

D．her explanation of a set of difficult understandings
66．Susan Sontag’s lasting fame was made upon____________.
A．a tireless，all-purpose cultural view
B．her lifelong watchword: seriousness
C．publishing books on morals
D．enjoying books worth reading and movies worth seeing

A．she was more a moralist than a sensualist
B．she was more a sensualist than a moralist
C．she believed repressed personalities mainly led to illness

Will you get a good job？ What will you do？ Many new graduates feel lost when they consider the endless list of career choices. They’ve invested a lot of money for their diploma（文凭）and now an important question stares them in the fact.
I’ve seen so many now graduates who do not know how to use the degree they have just earned. An example was Dave，who loved sports and had played baseball throughout his college years. He had his heart set on working for Nike. But he had never made clear in his own mind what kind of job he could do for Nike，so nothing ever happened. Another example was Allison，who was a history major. She wanted to work as an event planner，but unfortunately，no one hired her. Why？ No experience.
Failing to do some solid career exploration first，to get a clear idea of the types of jobs you can do，is a big error that many college students make. After our suggestion，Dave and Allison both found their jobs. To ensure a brighter future，follow these effective strategies：
—Make educated career choices. Identify the job you want. Conduct research. Ask parents to advise you on actual job duties. Consider what your natural talents are，and look for positions where you can use them.
—Don’t rely on the Internet. Networking is an effective tool—be sure it’s a job—hunting strategy you use. New studies from the Department of Labor state that only 4％ of job-seekers found their job on the Internet. The fact is that 63％ of all jobs are filled by contacts.
Employers are making quick decisions. Most people lose the job in the first minute of the interview. It’s deadly to let the employers focus quickly on how well you can perform the job.
—Practice your interviewing skills. Be ready for the tough questions by first writing out good answers to possible questions and having a role-playing interview with your friend.
60．What does the author seem to be most probable？
A．A job-hunter. 　　　　　　　B．A magazine editor.
C．A website owner. 　　　　　 D．A job-seeking adviser.
61．In order to be well prepared for the interview, you’d better ____________.
A．surf the Internet for contacts
B．get along well with your workmates
C．practice the interview for several times
D．take care of your dress
62．According to the text it is suggested that Dave should ____________.
A．let others know what he can do for them
B．study further to get a higher degree
C．give up his interest in playing basketball
D．take part-time jobs first
63．For Allison, she should ____________.
A．find a job in another field
B．find some work to gain work experience
C．not tell the employer her major
D．offer more personal information
