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.

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. |

No one knows where the phrase "Indian summer" got started, we are sure that the phrase was wellknown by the year 1778,because Crevecoeur, an American writer, described it like this:"a hard frost(霜冻)follows the autumn rains. This prepares the ground to receive the snows of winter. But before the snows come, the earth turns warm once again and there are a few days of smoke and mildness called Indian summer."
There is a story about Indian summer that goes back to the very first settlers of the New World. The first frost meant winter was coming. Snow would soon follow.
The Indians, seeing the settlers preparing for winter, told them not to hurry. The weather would turn warm again, mild breezes would blow and the sky would turn soft and smoky. And so it did. The sun became hotter,and a bright warm smoke flowed over the fields and woods. The settlers, remembering the words of the Indians, called this wonderful period Indian summer.
But the Indians have their own stories about this late period of warm weather. One of their stories is about a god called Shawondasee.
Shawondasee was a sad god because he had lost the love of a tall and beautiful Indian maiden. The sad and beautiful story caught the imagination of the American poet Henry Wadsworth Longfellow. In 1855 he included the story of Shawondasee in his poem "The song of Hiawatha".
The story goes like this: God Shawondasee, fat and lazy, lived under the dreamy and never-ending southern sun. He sent birds and wild geese to the north, as well as melons and grapes. He smoked a big pipe, and as the smoke rises, it filled the sky with dreamy softness, gave a bright shine to the water and brought the tender Indian summer to the melancholy northland.
There is something about this period of warm weather that gives people a lift and makes them feel warm and happy before the long snows of winter come.
61.Which season does "Indian summer" refer to?
A. Early spring. B. Late summer. C. Mid-autumn. D. Early winter.
62.Which of the following best describes the weather of this period of time?
A. Hot and humid. B. Warm and mild. C. Cool and bright. D. Cold and smoky.
63.The Indians" explanation to this natural phenomenon is that God Shawondasee_______.
A. lived under the dreamy southern sun B. took pity on the homeless settlers
C. smoked a lot because of his bad mood D. lent his smoking pipe to the Indians
64.What is the meaning of the underlined word "melancholy"?
A. Sad and lonely. B. Dreamy and exciting.
C. Soft and musical. D. Warm and happy. |

It seems as if cell phone could be the protection that parents expecting the kids to have freedom and be safe have been looking for. Let"s 41 your 11-year-old son is going on a long bike ride with a friend, so they take along your cell phone 42 they need help. Not only could they call you if necessary, but 43 Global Positioning Systems (GPS) equipped on many mobile phones today, your son and his friend could also be 44 easily.

All penguins (企鹅) swim in cold waters and so need a good layer of insulation (隔离), some species come ashore in hot places.Humboldt penguins,for example,nest in arid hot - 40°C, deserts on the west coast of South America, while others survive the lowest temperatures of any animals.Male Emperor penguins,as we know, spend the Antarctic winters incubating eggs in temperatures that can fall below -70°C. The insulation is provided in layers, under the skin is a thick layer of fat, then there is a layer of downy feathers that trap air, and finally another layer of waterproof feathers that keep the cold water away from the skin. With all this insulation penguins have no problem keeping warm at temperatures down to about -10°C - although they have special adaptations of the circulatory system to keep their feet from freezing and to prevent much heat loss through the feet that are on the ice. At lower temperatures penguins have to huddle (蜷缩) together to keep warm. In such huddles the penguins gradually move from the hot interior to the cold outside so that every penguin has his turn in the middle and on the outside.
In hot climates, penguins suffer greatly from overheating. They use several strategies to lose heat. They puff up their feathers so that air can circulate to their skin; they hold their flippers（脚蹼）out from their bodies and pump hot blood to them so that they can act as radiators; they open their mouths and breathe to lose heat from their hot breath; and those species that live in hot climates also have several bare patches of skin around the eyes and feet, they send blood to these bare patches when they are hot - you can recognize a hot penguin since it will have pink eye patches and pink patches on its feet.
77. Which of the following are the ways for penguins to keep warm?
a. staying together in good social order
b. several layers as radiators
c. a special circulatory system d. waterproof feathers
e. sending blood to bare patches
f. always staying in the middle
A. a, b, c B. a, c, d C. b, c, e D. c, d, f
78. The insulation consists of _______ layers.
A. two B. three C. four D. five
79. The underlined "puff up" in the second paragraph can be replaced by ______.
A. breathe deeply B. blow up C. hold tight D. spread out
80. The passage mainly tells us ______.
A. how penguins stay warm in cold places B. that penguins are a clever animal
C. how penguins keep their temperature D. why penguins can live a safe life |
Parents often believe that they have a good relationship with their teenagers. But last summer, Joanna and Henry noticed a change in their older son: suddenly he seemed to be talking far more to his friends than to his parents. “The door to his room is always shut.” Joanna noted.
Tina and Mark noticed similar changes in their 14-year-old daughter. ”She used to cuddle up with me on the sofa and talk,” said Mark. “Now we joke that she does this only when she wants something. Sometimes she wants to be treated like a little girl and sometimes like a young lady. The problem is figuring out which time is which.”
Before age 11, children like to tell their parents what’s on their minds. “ In fact, parents are first on the list.” Said Michael Riera, author of Uncommon Sense for Parents with Teenagers. “This completely changes during the teen years.” Riera explained. “They talk to their friends first, then maybe their teachers, and their parents last.”
Parents who know what’s going on in their teenagers’ lives are in the best position to help them. To break down the wall of silence, parents should create chances to understand what their children want to say, and try to find ways to talk and write to them. And they must give their children a mental break, for children also need freedom, though young. Another thing parents should remember is that to be a friend, not a manager, with their children is a better way to know them.
65．“The door to his room is always shut” suggests that the son________.
A．is always busy with his studies
B．doesn’t want to be disturbed
C．keeps himself away from his parents
D．begins to dislike his parents
66．What troubles Tina and Mark most is that_______
A．their daughter isn’t as lovely as before
B．they can’t read their daughter’s mind exactly
C．they don’t know what to say to their daughter
D．their daughter talks with them only when she needs help
67．Which of the following best explains ”the wall of silence” in the last paragraph?
A．Teenagers talk a lot with their friends.
B．Teenagers do not want to understand their parents.
C．Teenagers do not talk much with their parents.
D．Teenagers talk little about their own lives.
68．What can be learned from the passage?
A．Parents are unhappy with their growing children.
B．Parents have suitable ways to talk with their teenagers.
C．Parents should be patient with their silent teenagers.
D．Parent should try to understand their teenagers. |
