The Friday after the American holiday of Thanksgiving is called Black Friday. It’s said that it’s the day that store ledgers(分类账)move into the black and companies become profitable. On that day, retailers slash prices to get consumers to buy.  It is also a time when many Americans start their Christmas shopping. VOA’s Elizabeth Lee tells us how the economy may affect consumers on that bargain day.
“It’s just the deals, the sales and everything you can get for a lesser price,” said Sandy Thomas, a shopper. But it’s a nightmare for others. “I think it’s crazy. I’ve done all of my shopping throughout the week so I don’t have to go out on Friday,” she said. It’s called Black Friday, the start of the traditional Christmas shopping season in the United States. Every year it’s the day after the Thanksgiving holiday. Stores open before sunrise and there are deep discounts everywhere you look.
While the lead up to Christmas is known as the season of giving, Black Friday can get ugly.
Last year a crowd of bargain-hunters killed a Wal-mart worker in a New York suburb. This year, many stores are increasing security while they slash prices. “This is a huge time for the retail stores,” said Fred Joutz from George Washington University. “This is when they begin making their profits for the year.”
Economics professor Fred Joutz says how Americans spend the weekend after Thanksgiving is a good indication of how consumers feel about the future.
With the unemployment rate above 10 percent, Joutz says Americans are saving more and spending less. “Credit is still strictly controlled whether through credit cards or through borrowing from banks,” he said. Some retailers are attracting consumers by opening on Thanksgiving Day, when shops are traditionally closed.  Other stores open their doors anywhere from midnight to four in the morning.
And shoppers will be lining up in front of the doors in order to be one of the first ones to walk through and get a big discount. Electronics like flat screen TVs are usually the first items to go. Sandy Thomas says it’s an annual family tradition and well worth it. “I just save maybe half of what I would have spent on a regular, you know, shopping trip,” she said.
Economists say U.S. consumers will spend money this Black Friday, but they will spend it more carefully.     
59. The underlined word “slash” in the first paragraph probably means _________.
A. reduce         B. raise         C. increase        D. change
60. The sentence “This day should be a shopper’s dream.” should be placed between ________.
A. paragraph two and paragraph three        B. paragraph one and paragraph two
C. paragraph three and paragraph four             D. paragraph five and paragraph six
61. Why are many stores increasing security according to the passage?
A. Because there are too many people saving more and spending less.
B. Because it’s a time when they begin making their profits for the year.
C. Because last year a crowd of bargain-hunters caused an accident.
D. Because many stores open their doors from midnight to four a.m.
62.What can we learn from the passage?
A. Christmas shopping is traditional time and this year it is no exception.
B. Electronics like flat screen TVs are usually least discounted.
C. The economy only affects consumers on that bargain day.
D. Thanksgiving is a good indication of how consumers feel about the future.

Each cell in the human body contains about 25,000 to 35,000 genes, which carry information that determines your traits. Traits are characteristics you inherit from your parents; this means your parents pass some of their characteristics on to you through genes. For example, if both of your parents have green eyes, you might inherit the trait of green eyes from them. Or if your mom has freckles, you might inherit that trait and wind up with a freckled face. And genes aren’t just in humans — all animals and plants have genes, too.
Genes hang out all lined up on thread-like things called chromosomes. Chromosomes come in pairs, and there are hundreds, sometimes thousands of genes in one chromosome. The chromosomes and genes are made of DNA, which is short for deoxyribonucleic acid.
Chromosomes are found inside cells, the very small units that make up all living things. A cell is so tiny that you can only see it through the lens of a strong microscope, and there are billions of cells in your body. Most cells have one nucleus. The nucleus, which is sort of egg-shaped, is like the brain of the cell. It tells every part of the cell what to do. How does the nucleus know so much? It contains our chromosomes and genes. Tiny as it is, the nucleus has more information in it than the biggest dictionary you’ve ever seen.
71. What is the best title of this passage?
A. What Is a Gene?                    B. How Do Genes Work?
C. What Does A Gene Consist of?         D. How Do Nucleus Command Cells?
72. What does the underlined word “inherit” probably mean in the first paragraph?
A. carry          B. send        C. obtain           D. pass
73. Which of the following is NOT true according to the passage?
A. The parents pass some characteristics on to their children.
B. All living things receive traits from the old generations.
C. One’s green eyes might be passed on from the parents.
D.A mother’s freckled face might affect her young’s face.
74. From the passage we can know that______________.
A. genes can decide all your characteristics from parents.
B. genes exist inside cells that make up all living things.
C. genes tells every part of the cell what to do .
D. Chromosomes come in pairs containing genes.
75. From the passage we can conclude that ___________.
A. not all cells have one nucleus inside .
B. not all living things are made up of cells.
C. genes aren’t in humans but in animals and plants.
D. DNA is made of chromosomes and genes.

II 阅读理解(共25小题。第一节每小题2分,第二节每小题1分;满分45分)
第一节   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,并在答题卡上将该项涂黑。
  The Opera house in Santa Fe. New Mexico is one of the most beautiful ones in the United States. It is small and open, with one roof over the stage where singers perform and another roof over part of the audience. This opera house in the mountain is one of the best in the country, which may seem surprising because performances are only given during seven weeks in the summer, and because Santa Fe is a very small city.
  One reason why the Santa Fe Opera is so good is that it attracts many excellent young singers. They all hope to sing in famous opera houses like Metropolitan in New York someday, and they work hard to become well-known during the summer. The musicians and directors are experts who come from the best orchestras(管弦乐队) and operas in the country during their vacations. They enjoy working there because they like to live in Santa Fe, which is near both the mountains and the desert. It is very beautiful there in the summer.
  The state government of New Mexico advertises the Santa Fe Opera in newspapers all over the country, and a great many tourists come to New Mexico because of the opera. Still, most of the audience does come from Santa Fe and other nearby cities, and all the seats in the theater are sold for every show.
  There is only one thing that some people do not like about the Santa Fe Opera, and that is the cold weather. Because the theater is open, performances cannot start before it gets dark at nine o"clock in the evening, and then the mountain air becomes very cool. Sometimes people complain about the cold air, but because the operas are good, these people come back again---wearing warm coats.

  A. it is only a very small place  B. it is between the mountain and desert
  C. all the seats are old for every show  D. musicians there are from the best orchestras
 44.From the passage, we can learn that _____.

The day will come when my body will lie upon a white sheet neatly folded in under the four corners of a mattress located in a hospital busily occupied with the living and the dying. At a certain moment, a doctor will determine that my brain has ceased to function and that, to all intents and purposes, my life has stopped.
When that happens, do not attempt to instill artificial life into my body by the use of a machine. And don"t call this my deathbed. Let it be called the Bed of Life, and let my body be taken from it to help others lead fuller lives.
Give my sight to the man who has never seen a sunrise, a baby"s face or love in the eye of a woman. Give my heart to a person whose own heart has caused nothing but endless days of pain. Give my blood to the teenager who was pulled from the wreckage of his car, so that he might live to see his grandchildren play. Give my kidneys to one who depends on a machine to exist. Take my bones, every muscle, every fiber and nerve in my body, and find a way to make a crippled child walk.
Explore every corner of my brain. Take my cells, if necessary, and let them grow so that, someday, a speechless boy will shout at the crack of a bat, and a deaf girl will hear the sound of rain against her window.
Burn what is left of me and scatter the ashes to the winds to help the flowers grow. If you must bury something, let it be my faults, my weaknesses and all prejudice against my fellow man.
If, by chance, you wish to remember me, do it with a kind deed or word to someone who needs you. If you do all I have asked, I will live forever.

Botswana lies immediately to the north of South Africa. It is bordered on the north and west by Namibia, on the north and east by Zimbabwe, and is connected by a narrow strip of land on the northern border to Zambia. Its territory consists almost entirely of a broad, flat, arid subtropical plateau(高原), though there are hills in the eastern part of the country.
In the northwest, the Okavango River empties into the Kalahari sands, creating the largest inland river delta in the world. While the Okavango Delta is home to relatively few large animals in comparison to other areas of Botswana, its clear waters and countless small islands are home to a variety of birds, plants, and smaller species of animals.
Nearby is Chobe National Park, a beautiful grassland reserve(保护区) that has gained international fame for its large elephant population. Southeast of Chobe are Botswana"s large Makgadikgadi salt pans, home to numbers of blue wildebeest, several antelope species, and those international lovers of salt pans, flamingos(a kind of birds).
Almost the entire remaining portion of the country is covered by the Kalahari Desert--a varied environment of sand and grassland. Although this area of Botswana is where few people live, it is one of the richest wildlife areas in all of Africa.
Botswana"s two largest parks, the Central Kalahari Game reserve and Gemsbok National Park, are found in this region.
Botswana"s climate can get rather cool, particularly during the dry winter months of June to August when night occasionally brings frost. The rainy summer months (December through March) are best avoided for those interested in enjoying the best game viewing conditions.

For years scientists have been concerned about the effects of air pollution on the earth"s natural conditions. Some believe the air inside many houses may be more dangerous than the air outside. It may be one hundred times worse.
Indoor air pollution can cause a person to feel tired,to suffer eye pain, headache and other problems.Some pollutants(污染物)can cause breathing disorders,diseases of blood and even cancer. Most scientists agree that every modern house has some kind of indoor pollution.People began to notice the problem in the early 1970s.It is said that when builders began making houses and offices they did not want to waste energy.To do this,they built buildings that limited the flow of air between inside and outside.They also began using man-made building materials.These materials are now known to let out harmful gases.As the problem became more serious, scientists began searching for a way to deal with it.They discovered a natural pollution control system for building-green plants.Scientists do not really know how plants control air pollution.They believe that a plant"s leaves absorb or take in the pollutants.In exchange the plant lets out oxygen through its leaves and through its tiny organizations on its roots.Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square metres of space.Studies of different plants show that each absorbs different chemicals.So the most effective way to clean the air is to use different kinds of plants.Having green plants inside your house can make it a prettier and healthier place.
77.What is the topic of the passage?
A.Air pollution.           
B.Green plants indoors.
C.Indoor air pollution.         
D.Environment protecting.
78.What makes indoor air pollution more harmful than that of the air outside?
A.The limited flow of air indoors.
B.Man-made building materials.
C.Fewer green plants inside houses.     
D.The energy-saving materials indoors.
79.The most effective way to clean the air is to use different kinds of plants because______.
A.they can make houses pettier and healthier
B.they may let out oxygen which people need
C.they can take in all kinds of indoor pollutants  
D.they can absorb different harmful indoor chemicals
80.Which of the following is implied but NOT stated?
A.keep windows open and let fresh air in.
B.Scientists have a clear idea how plants control air pollution.
C.Oxygen is let out through the leaves and roots of the plants.
D.Green plants are a natural pollution control system for building.
