题目内容

You can not see any object unless light from that object gets into your eyes. Some of the things you see give off light of their own. The sun, the stars, a lighted lamp are examples that can be seen by their own light. Such things are luminous. Most of the things you see are not giving off light of their own. They are simply reflecting light that falls on them from the sun or some other luminous bodies. The moon, for example, does not give off any light of its own. It is non-luminous. You see it because sunlight falls on it and some of it reflects in our direction. So moon light is only second hand sunlight.
When you look at a book, it sends to your eyes some of the light which falls on it, and you see the book. If light could be kept out from where you are so that there would be no light for the book to reflect, then you could not see the book even with your eyes wide open.
Light travels so fast that the time in which it travels from the book you are reading to your eyes is so short as if there were no time at all. Light reaches us from the moon, which is about 380 000 kilometers away, in only a little more than a second.
小题1:You can see the book because_______.

A．your eyes are close to it	B．it reflects some of the sunlight
C．it has light of its own	D．your eyesight can get to it

小题2:The underlined word “luminous” means_______.

A．All the things you can see give off light.

B．Light from the book is much shorter than that from the moon.

C．The moment you open your eyes the light from the book travels to your eyes.

D．Light travels so fast that there is no time for you to read.

Dash of Hope
"Dash" is a symbol which represents every day we’ve spent alive on earth．Therefore, how you spend your "dash" is important．
Recently I   36  about a little girl named Hope．After learning more about her life, I couldn’t help but feel it was not by   37  , nor happenstance, that she had been named "Hope"．The strong feeling of sympathy and generosity 38  in her young heart made a lasting impression on me and countless others． 39   I never had the opportunity to meet her, I wish I had．It seems as though she was wise beyond her tender years and very, very special．
Hope was a twelve-year-old girl who was   40  a "wish" in early December 2010 by the "Make-A-Wish" Foundation after being   41  that she had a rare type of bone cancer．However, when she found out that more than 150   42  in her area were waiting for their wishes to be granted （实现） , she unselfishly used her wish to   43  that those children have their wishes granted．She also asked tW it be done   44  January 16, 2011．Unfortunately, however, the organization informed her that her   45  request could not be granted as the funds （资金） were simply   46 ．They calculated that they would need to raise more than one   47  dollars in thirty days in order to grant her wish． 48 , but not discouraged, she turned her disappointment into an enthusiasm that inspired caring   49  to take up helping grant the wishes of the other children, and eventually   50   as well．Newspaper columnists and reporters for radio and TV stations 51   the story of this caring young girl who had   52  the hearts of so many and as word spread, the community was challenged．Committees were fanned and schools, corporations and various organizations assisted in  53  money to help make Hope’s dream come true．
Her efforts were not in vain as they continue to help others, not only   54  , but spiritually and emotionally as well．At the gathering to celebrate her life, "A Celebration of Hope" on January 16, 2011 , the   55  was made that they had indeed received donations totaling more than one million dollars．Her wish had been granted!

Our thoughts, words, and actions often cause harm to others and to us. Without reconciliation (和解), we cannot deepen our understanding and only cause more suffering. "Beginning Anew" is a(n) 1 of reconciliation. It involves three steps —— sharing appreciation, expressing 2 , and expressing hurt and difficulties.
In the first step, we share appreciation. We acknowledge the 3 qualities of the other person. The second step——expressing regret, is to 4 with the other person our regrets for the things we have done or said that might have caused him or her 5 . This requires humility (谦逊), and the 6 to let go of our own pride. In the third step, we express our own hurt with mindful and loving 7 without blaming or criticizing. We speak in such a way that the other person can listen and 8 our words. If we blame the other person, his heart will 9 and he will not be able to hear us. We ask the other person to help us to understand why he has spoken and acted as he has, causing us so much pain. Perhaps, later, he can share his feelings so that we can understand him more deeply. If a strong 10 arises in us while we are expressing our suffering, we should simply 11 and come back to our breathing until the emotion becomes 12 . The other person can 13 us by following his breathing until we are ready to continue. We can enjoy practicing "Beginning Anew" with our partner, our family, or our friends 14 . By doing this, we will 15 misunderstandings from accumulating. Rather, we will take care of them as they arise, as we take care of our children.

In the Caucasus region of the Soviet Union, nearly 50 out of every 100,000 people live to celebrate their 100^th birthday, and many don’t stop at 100! By comparison, in America only 3 people in 100,000 reach 100. But these Soviet old people aren’t alone. The Pakistani Hunzas, who live high in the Himalaya Mountains, and the Vilacbambans of the Andes Mountains in Ecuador seem to share the secret of long too.
These peoples remain healthy in body and spirit despite the passage of time. While many older persons in industrial societies become weak and ill in their 60s and 70s, some Soviet Georgians, aged 110 to 140, work in the fields beside their great- great- grandchildren. Even the idea of aging is foreign to them. When asked, “At what age does youth end?”, most of these old people has no answer. Several replied, “Well, perhaps at age 80.” The very youngest estimate was age 60.
What accounts for this ability to survive to such old age, and to survive so well? First of all, hard physical work is a way of life for all of these long-lived peoples. They begin their long days

of physical labor as children and never seem to stop. For example, Mr. Rustam Mamedov is 142 years of age. He remember his life experiences: the Grimean War of 1854; the Turkish War of 1878; the Bolshevik Revolution in 1917. His wife is 116 years old. They have been married for 90 years. Mr. Mamedov has no intentions of retiring from his life as a farmer. “Why? What else would I do?” he asks. Oh, he has slowed down a bit. Now he might quit for the day after 6 hours in the field instead of 10.
All these people get healthful rewards from the environment in which they work. They all come from mountainous regions. They live and work at elevations of 5,000 to 12,000 feet (1,660 to 4,000 meters) above sea level. The air has less oxygen and is pollutionfree. This reduced-oxygen environment makes the heart and blood vessel system stronger.
Another factor that may contribute to the good health of these people is their isolation. To a great ext

ent, they are separated from the pressures and worried of industrial society.
Inherited factors also play some role. Most of the longest-lived people had parents and grandparents who also reached very old ages. Good family genes may, therefore, be one factor in living longer.
Finally, although these three groups don’t eat exactly the same foods, their diets are similar. The Hunzas, Vilacbambans, and Soviets eat little animal meat

. Their diets are full of fresh fruits, vegetables, nuts, grains, cheese, and milk. They never eat more food than their bodies need.
It is clear that isolation from urban pressures and pollution, clean mountain air, daily hard work, moderate diets, good genes, and a youthful approach to life all contribute to the health and remarkable long life of all these people.
小题1: What kinds of things contribute to the remarkable long life of these peoples?

A．Moderate diets	B．Clean mountain air.
C．Daily hard work.	D．All the above factors（因素）.

小题2: How do you think the author feels about these long-lived people?

A．He is impressed with them	B．He doesn’t care.
C．He doesn’t like them.	D．He admires them.

小题3:According to the passage, the phrase “the passage of time” means .

A．have time to do what they want	B．being on time
C．time going by	D．limited time

小题4:In the passage, why does the author describe Mr. Mamedov?

A．An example of a typical long life among these people.

B．An example of an unusual long life among these people.

C．An explanation of why he is still healthy.

D．An example of why his wife died early than him.

小题5:What is the main subject of this article?

A．Mr. Mamedov’s life.

B．A description of several societies where people live a long time.

C．Suggestions for how you can live long life.

D．People are healthy in mountainous regions.

Job sharing refers to the situation in which two people divide the responsibility of one full-time job. The people willingly act as part-time workers, enough hours between them to fulfill the duties of a full-time worker. If they each work half the job, for example, they each receive 50 percent of the job’s wages, its holidays and its other benefits.
Job sharing differs from conventional(常规的) part-time work in that it occurs mainly in the more highly skilled and professional areas, which require higher levels of responsibility and employee commitment.
Job sharing should not be confused with the term work sharing, which refers to increasing the number of jobs by reducing the number of hours of each existing job, thus offering more positions to the growing number of unemployed people. Job sharing by contrast, is not designed to address the growing number of unemployed people. Job sharing, by contrast, is not designed to address unemployment problems; its focus, rather is to provide well-paid work for skilled workers and professionals who want more free time for other activities.
As would be expected, most job sharers are women. A survey carried out in 1988 by Britain’s Equal Opportunities Commission showed that 78 per cent of sharers were female, the majority of whom were between 20 and 40 years of age. Subsequent studies have come up with similar results. Many of these women were re-entering the job market after having had children, but they chose not to seek part-time work because it would have meant lower status. Job sharing also offered an acceptable shift back into full-time work after a long absence.
The necessity of close cooperation when sharing a job with another person makes the actual work quite different from conventional one-position jobs. However, to ensure a greater chance that the partnership will succeed, each person needs to know the strengths, weaknesses and preferences of his or her partner before applying for a position. Moreover, there must be a fair division of both routine tasks and interesting ones. In sum, for a position to be job-shared well, the two individuals must be well matched and must treat each other as equals.
小题1:In what way is work sharing different from job sharing?

A．Work sharing requires more working hours.

B．Work sharing is aimed at creating more jobs.

C．Work sharing provides a more satisfactory salary.

D．Work sharing depends on the employer’s decision.

小题2:According to paragraph4, young mothers preferred job sharing to conventional part-time work mainly because______.

A．they sought higher social status

B．they were over ideal working ages

C．they had difficulty finding full-time jobs

D．they had to take care of both work and family

小题3:In job sharing the partners should ______.

A．enjoy equal social status

B．have similar work experience

C．keep in touch with each other

D．know each other very well

“Mum, what does it mean when someone tells you that they have a skeleton (骨骼) in the closet (衣橱)?” Jessica asked. “A skeleton in the closet?” her mother paused thoughtfully. “Well, it's something that you would rather not have anyone else know about. For example, if in the past, someone in Dad's family had been arrested for stealing a horse, it would be 'a skeleton in his family's closet'. He really wouldn't want any neighbor to know about it.”
“Why pick on my family?” Jessica's father said with anger. “Your family history isn't so good, you know. Wasn't your great-great-grandfather a prisoner who was transported to Australia for his crimes?”“Yes, but people these days say that you are not a real Australian unless your ancestors arrived as prisoners.”“Gosh, sorry I asked. I think I understand now,” Jessica cut in before things grew worse.
After dinner, the house was very quiet. Jessica's parents were still quite angry with each other. Her mother was ironing clothes and every now and then she glared at her husband, who hid behind his newspaper pretending to read. When she finished, she gathered the freshly pressed clothes in her arms and walked to Jessica's closet. Just as she opened the door and reached in to hang a skirt

, a bony arm stuck out from the dark depths and a bundle of white bones fell to the floor. Jessica's mother sank in a faint (晕倒), waking only when Jessica put a cold, wet cloth on her forehead. She looked up to see the worried faces of her husband and daughter.
“What happened? Where am I?” she asked. “You just destroyed the school's skeleton, Mum,” explained Jessica. “I brought it home to help me with my health project. I meant to tell you, but it seemed that as soon as I mentioned skeletons and closets, it caused a problem between you and Dad.” Jessica looked in amazement as her parents began to laugh madly. “They're both crazy,” she thought.
小题1:According to Jessica's mother, “a skeleton in the close” means ________.

A．a family honor

B．a family secret

C．a family story

D．a family treasure

小题2:What can we learn about some Australians' ancestors from Paragraph 2?

A．They were brought to Australia as prisoners.

B．They were the earliest people living in Australia.

C．They were involved in some crimes in Australia.

D．They were not regarded as criminals in their days.

小题3:Why did Jessica bring a skeleton home?

A．She was curious about it.	B．She planned to keep it for fun.
C．She needed it for her school task.	D．She intended to scare her parents.

小题4: Jessica's parents laughed madly at the end of the story probably because ________.

A．they were crazy.

B．they were over excited.

C．they realized their misunderstanding.

D．they both thought they had won the quarrel.

Geena David knew she wanted to be a movie star when she was very young. She was not sure what gave her the idea, but she wanted to look like a movie star. “I have a lot of pictures from my childhood of me wearing sunglasses,” she says. “I used to wear them to watch TV.”
　 Early movie actors started wearing sunglasses not because they looked good, but because their eyes hurt. The l

ights used on movie sets were extremely bright and could cause a painful

problem known as “Klieg eyes”. It was named after the Klieg brothers who invented the lights. Actors wore sunglasses to give their eyes a rest. But when movie stars began wearing their sunglasses in public, they quickly became a must.
　 Eventually actors started wearing sunglasses in their movies as well as on the street. Audrey Hephburn wore ultra-cool Ray-Ban sunglasses in the 1961 movie, Breakfast at Tiffany’s. As a result, Ray-Ban sunglasses started to appear more and more in the movies. In 1979, Ray-Ban “Wayfarers” were worn by Jake and Elwood in The Blue Brothers. Tom Cruise wore Ray-Ban “Aviator” sunglasses in the 1986 hit, Top Gun. Then in 1997, Will Smith and Tommy Lee Jones made Ray-Ban “Predator” sunglasses famous in Men in Black.
　 Of course sunglasses aren’t just a fashion statement. The main reason to wear sunglasses is to protect our eyes against UV radiation. UV radiation can damage our eyes, so people now choose their sunglasses carefully. But you don’t have to give up style for safety. The choice of frames and lenses available these days is huge. So you can protect your eyes and still be the coolest person on the beach.
小题1:What is mainly discussed in this passage?

A．The use of sunglasses.	B．The history of sunglasses.
C．The sunglasses wearing.	D．Why movie stars like to wear sunglasses.

小题2:Why did Geena David like to wear sunglasses?

A．She was a movie star.

小题3:Early actors’ eyes hurt because ______.

D．their scripts were written in very small writing

小题4:Now people wear sunglasses ______.

A．just to protect their eyes	B．for fashion and to protect their eyes
C．because of bright lights	D．because movie stars wear them
