The one thing I can 34 from surfing and not any other sport is endless challenge. Y ou can never be the “best surfer” because the ocean 35 an uncountable variety of waves that nobody can ever master. The variations of surfing styles are wonderful. Some surfers are free and flowing; others are very aggressive（活跃有力的）and 36 . All of these things attract me to surfing and make it 37 from any other sport.
I’ve tired to tell every girl I know to do something that people don’t think girls can do. It’s part of being human to advance to new 38 , so shouldn’t it be expected that girls should step up and start pushing the limits of things boys and men used to dominate (主宰)?

III.Reading Comprehension (20%)
(A)
In Gospost, a small town on Plymouth Bay, there lived an attractive young woman named Harriet Magnis, who loved her husband deeply, but she failed to provide him with a child. And she feared that her husband Richard, a gunner in the Royal Navy, would leave her forever.
Richard was at sea for two years and was home for only a few days at a time. One day Harriet wrote him a letter telling him that he would be the father of a baby by the time he got home again. Months passed, Harriet wrote to tell her husband that the baby had come, and it was a boy.
When Richard came home, the first thing he wanted to do was to see his son. But Harriet told him that the doctor felt the sea air was bad for the baby, so she had taken him to his grandparents, who lived in Scotland. The next time Richard came home, she had another excuse. Next time, still another. Richard began to suspect that she was hiding the child because it was another man’s. So he told Harriet that next time he would see his son --- and no excuses would be accepted. Poor Harriet knew that she either had to produce a 3-year-old boy, or had to spill the whole truth to him.
A Mrs. Charles went to London to see her doctor, taking two children with her: Mary, five, and Thomas, three. Before seeing the doctor, she left her children with the grocer’s wife, who promised to watch them. When she came to pick up her children, she was told that Thomas was missing. The police were informed, and a nationwide search was begun. At the same time Harriet proudly took little Thomas down to Portsmouth to see his daddy’s ship come in. How delighted Richard was! For the few days of his shore leave, he felt himself the happiest father of a son.
Of course, Harriet couldn’t escape being arrested, but she was discharged and never tried again, because she committed the crime in London, not in Hampshire. The judge may have understood better than anyone else. His wife was also unable to bear children. But instead of stealing else’s child, she had committed suicide（自杀）.
41. What was the reason that little Thomas was missing?
A. The grocer’s wife failed to carry out her promise.
B. Harriet stole him from the grocery.
C. The boy wanted to see his daddy’s ship.
D. Mrs. Charles didn’t watch him properly.
42. Where is the small town Gospost located?
A. In Hampshire
B. Near London
C. In Scotland
D. Next to Portsmouth
43. How long did Harriet conceal from her husband the truth that they had no baby at all?
A. Several months.
B. Two years.
C. Three years.
D. Five years.
44. Why was Harriet not tried for the crime she had committed?
A. Because she was wise to have committed the crime she had committed.
B. Because she had not done any harm to the baby.
C. Because Harriet had committed suicide.
D. Probably because the judge had sympathy with her.

Hong Kong is a group of rocky islands surrounding a mainland area. It is a great port where goods from all over the world are brought in and then shipped out to other lands. It is a popular tourist spot and a center of commerce, manufacturing, and banking. It is also a bustling（喧嚣）place of people and movement, of great riches and extreme poverty, of bright, vivid colors and dull, gray ugliness.
Hong Kong is one of the most densely populated（人口稠密的）places on earth. More than 6,300,000 people are crowded into a total land area of only 1,076 square kilometers. Almost all the people are Chinese. The two official languages are English and the Cantonese dialect of Chinese.
Most of the people of Hong Kong live in its cities. The major cities are V ictoria, the capital, which is on Hong Kong island, and Kowloon, which lies across the harbor of Hong Kong on Kowloon peninsula (半岛). Because of the dense population and the shortage of living space, some of the people live on small boats in Hong Kong harbor.
Hong Kong is marked by contrast between new and old, rich and poor. There are wide, well-paved streets with modern office buildings, department stores, theatres, and fashionable hotels. New apartment houses are found in many parts of Hong Kong. But only a few blocks away are slums（平民窟）,where the streets are narrow, and the buildings are old and crowded. Because housing has been in short supply, the government passed laws in 1980 to try to reduce the large number of illegal immigrants entering Hong Kong.
45. It can be learnt from the passage that Hong Kong is _____.
A. a lively and flourishing harbor city
B. the most densely populated place on earth
C. a group of islands surrounded by a mainland area
D. inhabited entirely by Chinese people
46. There are some boat dwellers（居住者）in Hong Kong because of _____.
A. the poor living standard of some people
B. the dense population and the short supply of housing
C. the advantages of living in Hong Kong harbor
D. the good living conditions on small boats
47. What is the best title for this passage?
A. Hong Kong And Its People
B. The Geographic Location of Hong Kong
C. The Population Distribution in Hong Kong
The Economic Development of Hong Kong
(C)
While their life span（寿命）continues to grow, Americans might be surprised to learn that it doesn’t even come close to the top 25. According to a survey done by the Associated Press, the United States ranks 41st in lifespan, behind most of Europe, Japan, Jordan and Singapore. The United States’ life expectancy (average age of 77.9 years) is much lower than 20 years ago, when it ranked 11th, the A.P. reports.
One of the reasons for the decline in ranking is the U.S. having world’s highest obesity rates. Another reason is a five year difference in lifespan between white and black Americans (black Americans’average lifespan is 73.5 years), according to research proved by the U.S. Census Bureau and the National Center for Health Statistics.
“The U.S. has the resources that allow people to get lazy and thus fat,’ Paul Terry, an assistant professor of epidemiology（流行病学）at Emory University in Atlanta, told the A.P. “We have the luxury of choosing a bad lifestyle as opposed to having one imposed（强加）on us by hard times.”
And where do people live the longest? According to the U.S. Census Bureau, the country with that honor is Andorra, a tiny country in the Pyrenees between France and Spain, with an average life expectancy of 83.5 years.
48. Where did Americans’ life expectancy rank in the 1980s?
A. 11th
B. 25th
C. 41st
D. Not mentioned.
49. What is white Americans average lifespan according to the research by authoritative organizations?
A. 77.9 years
B. 73.5 years
C. 83.5 years
D. Over 77.9 years
50. The word “obesity” in the 2nd paragraph most probably means _____.
A. being lazy
B. being fat
C. being poor
D. luxury
51. What does the writer mean by saying “We have the luxury of choosing a bad lifestyle as opposed to having one imposed on us by hard times.”?
A. The lifestyle in hard times was better than that we have nowadays.
B. We are opposed to a bad lifestyle.
C. A wealthy life is the cause of a bad lifestyle.
D. We prefer a bad lifestyle to a good one.
(D)
“Time is a problem for kids,” states a news report for a new Swiss watch. Children in some countries “learn time slowly” because “they don’t wear watches” and “parents don’t really know how to teach them time”. The kids grow up with this handicap and become adults --- and they can’t get to work on time. Is there an answer to this problem? Of course --- it’s the Flik Flak, made by a famous Swiss watch company.
The Flik Flak is being marketed as something of a teaching watch for children aged 4 to 10. The watch itself does not teach kids how to tell time, of course; it merely “captures their imagination” by presenting the “hour” hand as a beautiful red girl named Flak and the “minute”hand as tall blue boy named Flik. Flik points to corresponding “blue” minutes on the dial, while Flak points to red hour numbers. The characters and the colors combined with parental help, are supposed to teach young children how to tell time.
The watch comes equipped with a standard battery and a nylon band. Peter Lipkin, the United States sales manager for the Flik Flak, calls it “kidproof: if it gets dirty you can throw the whole watch in the washing machine.”The product is being sold in select department stores in Europe, Asia and the United States for a suggested price of 25%. Parents who buy the watch may discover that it is one thing to tell time; it’s quite another thing to be on time.
52. From the news report we know that _____.
A. parents are patient when teaching children time
B. parents have little idea of how to teach children time
C. children tend to learn time quickly
D. children enjoy wearing the Flik Flak watch
53. The word “handicap” (Para.1, Line 3) means _____.
A. displeasure
B. discouragement
C. disappointment
D. disadvantage
54. Flik and Flak in the passage stand for _____.
A. a tall boy and a beautiful girl
B. the minute hand and the hour hand
C. the Swiss watch company
D. the designers of the watch
55. The United States sales manager calls the new watch “kidproof” because _____?
A. it is designed to teach children to be on time
B. it proves to be effective in teaching children time
C. it is made so as not to be easily damaged by children
D. it is the children’s favourite watch
56. _____
If you think you’re cutting calories by eating diet or low-calorie versions of your favourite foods, think again. A new study by Canadian scientists suggests that our bodies can’t be fooled that easily.
57. _____
Researchers at the University of Alberta studied the eating habits of young rats, and found that they tended to overeat when they were fed “diet” foods. Professors David Pierce trained his rats to associate low-calorie foods with a “diet” taste, and high-calorie foods with a different taste. So, when the rats were fed a high-calorie food with the diet taste, their brains assumed that their bodies were running low on calories. The rats then overate at their next meal in an effort to make up for the lost energy.
58. _____
Though conducted in animals, the new study adds to a growing body of research in humans that suggests that the more low-calorie (or even zero-calorie) sodas and foods you consume, the more your body demands payback for the calories it was deprived. Scientists at the University of Texas reported in an eight-year study that for every can of diet soda that a person drank, he raised his risk of being overweight by 41%. Another study of diet-soda drinkers came to a similar conclusion that soda drinkers had a 48% higher risk of metabolic syndrome （新陈代谢综合症）than non-soda drinker.
59. _____
This research could make the food and drink industry a bit uneasy. This study simply challenges common sense. To suggest that foods and drinks with zero calories contribute to weight gain is contrary to scientific evidence that supports that they can help you reduce calories and maintain a healthy weight.
60. _____
However, none of the studies has yet proved that diet foods or drinks actually weight gain or heart disease; they have merely found a fascinating association, which scientists are still trying to explain.

Many people, especially those who think they are not as talented as others, tend
to give up in their undertakings and thus complain about life. Such people will
certainly end up getting nowhere. Notice that most successful people are not unlike
us. What makes them stand out is their devotedness to the job they are doing, which
is typical of the story of Li Dahua, a neighbor of mine. Dahua was brought up in
a poor family. Since he didn't do well in school, he joined his father in collecting
garbage for a living soon after he graduated from elementary school. His neighbors
shook their heads whenever they saw him, thinking that this boy would by no means
carve out a bright future. Years passed by, and Dahua kept collecting garbage, but
he took one step further. Through books he knew how to sort out the waste he had
collected and have it recycled. You know what? He has set up a recycling factory
and become the richest man in town! His success proves the ancient Chinese saying:
"There must be a use for my talent."
