Against the assumption that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.
This finding suggests that taking steps to prevent northern forest fires to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.
This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat.
Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone（臭氧）levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling.
“We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere.” Scientists tracked the change in amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicated, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth. According to the new findings, taking steps to prevent northern forest fires may _______.
| A．result in a warming climate | B．cause the forest fires to occur more frequently |
| C．lead to a longer fire season | D．protect the forests and the environment there |
Earlier studies about northern forest fires ________.
| A．analyze all aspects of how northern fires influence climate |
| B．indicate that forest fires will pollute the atmosphere |
| C．suggest that people should take measures to protect environment |
| D．suggest that the fires will speed up climate warming |
The underlined phrase “soaked up” in the last paragraph most probably means ________.
| A．released | B．absorbed | C．created | D．disturbed |
From the text we can draw a conclusion that forest fires in Alaska, Canada and Siberia may ______.
| A．warm the climate as the assumption goes |
| B．allow more snow to reflect more sunlight into space and thus cool the climate |
| C．destroy large areas of forests and pollute the far-off sea ice |
| D．help to gain more energy rather than release more energy |
No one could have failed to be moved had he watched the live televised volleyball game between the Chinese and Cuban women's teams. As we sat before the television set, with our eyes fixed on the screen, we experienced every kind of feeling. When the two teams played neck and neck, we were on pins and needles, anxious as to what would come next, and when our team fell behind our hearts were in our mouths. Watching the game between those two teams is not only a matter of great joy. For more than that it provides food for thought. Just see how the Chinese women won the game ──by their co ──operation (合作), by their excellent skill, their effort and strong will. A Chinese saying goes, "When two competent opponents (比赛的双方) meet, the strong ──minded one will win. "This is the spirit of the Chinese Women's Volleyball Team. If every Chinese showed some of the spirit, never losing heart in times of difficulty and remaining clear ──minded in times of advantage (优势), then our nation would stand in the vanguard (前列) of the world family of nations, just as the Chinese Women's Volleyball Team has done, is doing and will do.

Mr. Fitzpatrick has given much attention to his “Weight reduction” (减轻体重) programs. Just last year, for example, when he was the main speaker at the company dinner, he said he put on twenty pounds instead of losing thirty he promised he would.
The year before that, he joined a health club. He exercised every day and ate less food. At the end of three months, however, he began making excuses about why he couldn’t go there more often.
After the health club failed to work, he joined Weight Watchers but stopped going because he was the only man there. And he hated following any of the diet programs. Fitz’s latest idea is to join a walking club to “walk off” the weight.
41. Mr. Fitzpatrick was ________ when spoke at the company dinner last year.
A. lighter than the year before B. planning to go on a diet
heavier than the year before D. with the Weight Watchers
42. He did not stay with Weight Watchers because ________.
A. he couldn’t do as the diet programs required him
B. he felt uncomfortable being watched by women
C. the members of Weight Watchers were all women but him
D. both A and C
43. Which of the following can best explain the main idea of the passage?
A. There is no good way to lose weight. B. One can do nothing without a strong will.
C. There are different ways to lose weight. D. Walking is the best way of losing weight.
What makes one person more intelligent than another? What makes one person a genius, like the brilliant Albert Einstein, and another person a fool? Are people born intelligent or stupid, or is intelligence the result of where and how you live? These are very old questions and the answers to them are still not clear.
We know, however, that just being born with a good mind is not enough. In some ways, the mind is like a leg or an arm muscle. It needs exercise. Mental (done with the mind) exercise is particularly important for young children. Many child psychologists (心理学家) think that parents should play with their children more often and give them problems to think about. The children are then more likely to grow up bright and intelligent. If, on the other hand, children are left alone a great deal with nothing to do, they are more likely to become dull and unintelligent.
Parents should also be careful with what they say to young children. According to some psychologists, if parents are always telling a child that he or she is a fool or an idiot, then the child is more likely to keep doing silly and foolish things. So it is probably better for parents to say very positive (helpful) things to their children, such as “That was a very clever thing you did.” or “You are such a smart child.”
36. The words “intelligent” and “brilliant” in the first paragraph probably mean _______ while “dull” in the second paragraph means ________.
A. bright and splendid; slow in thinking and understanding
B. pretty and handsome; ordinary-looking
great and important; common
D. hopeful and helpful; careless
37. According to the context we can guess that a genius is ________ while an idiot is ________.
A. a normal person; a funny person
B. a strong person; a weak persona highly intelligent person; a foolish or weak-minded person
D. a famous person; an ordinary person
38. A person ________ is more likely to become a genius.
A. whose parents are clever
B. often thinking about difficult problemsoften helped by his parents and teachers
D. born with a good brain and putting it into active use
39. It is better for parents ________.
A. to praise and encourage their children more often
B. to be hard on their childrento leave their children alone with nothing to do
D. to give their children as much help as possible
40. Which of the following is NOT true according to the article?
A. Parents play an important part in their children’s growth.
B. The less you use your mind the duller you may become.
C. Intelligence is obviously the result of where and how you live.
D. What makes a person bright or stupid is still under discussion.
What should you think about when trying to find your career? You are probably better at some school subjects than others. These may show strengths that you can use in your work. A boy who is good at mathematics can use that in an engineering career. A girl who spells well and likes English may be good at office work. So it is important to know the subjects you do well in at school. On the other hand, you may not have any specially strong subjects but your records show a general satisfactory standard. Although not all subjects can be used directly in a job, they may have indirect value. A knowledge of history is not required for most jobs but if history is one of your good subjects you will have learned to remember facts and details. This is an ability that can be useful in many jobs.
Your school may have taught you skills, such as typing or technical drawing, which you can use in your work.. You may be good at metalwork or cookery and look for a job where you can improve these skills. If you have had a part-time job on Saturdays or in the summer, think what you gained from it. If nothing else, you may have learned how to get to work on time, to follow instructions and to get on with older workers. You may have learned to give correct change in a shop, for example. Just as important, you may become interested in a particular industry or career you see from the inside in a part-time job.
Facing your weak points is also part of knowing yourself. You may be all thumbs when you handle tools; perhaps you are a poor speller or cannot add up a column of figures. It is better to face any weakness than to pretend they do not exist. Your school record, for instance, may not be too good, yet it is an important part of your background. You should not be apologetic(认错的) about it but instead recognize that you will have a chance of a fresh start at work.
67．What is the passage mainly about?
A．The importance of working hard at school.
B．Choosing a career according to one’s strengths.
C．How to face one’s weakness. D．The value of school work.
68. The writer thinks that a student have a part-time job is probably ___.
A. a good way to find out his weak points B. one of the best ways of earning extra money
C. of great use for his work in the future D. a waste of time he could have spent on study
69．From the passage we learn that if a student’s school performance is not good, he _______.
A．should pay more attention to learning skills and developing abilities
B．will be regretful about his bad results
C．may also do well in his future work D．should restart his study in school
70. The underlined phrase “be all thumbs” (in Para 3) probably means “_______”.
A. be clumsy at doing things B. be skillful in doing things
C. be not interested in certain things D. be easily bored in doing things
