Zanzibar,Tanzania--Hundreds of dead dolphins were washed up on Friday along the shore of a popular tourist place on Tanzania’s northern coast.Scientists have ruled out poisoning.
It was not immediately clear what killed the 400 dolphins,whose dead bodies lied along a 4-kilometer coast of Nungwi,said Narriman Jidawi,a marine biologist at the Institute of Marine Science in Zanzibar.But the bottleneck dolphins,which live in deep offshore waters,had empty stomachs,meaning they could have got lost and had been swimming for some time to reorient themselves.They did not die of hunger and were not poisoned,Jidawi said.
In the US,experts were looking into the possibility that sonar(聲吶)from the US submarine could have caused a similar incident in Marothon,F(xiàn)lorida,where 68 deep-water dolphins stranded(擱淺)themselves in March 2005.
The deaths are a blow to the tourism industry in Zanzibar,where thousands of visitors go to watch and swim with dolphins.Villagers,fishermen and hotel residents found the dead bodies and told officials.Mussa Aboud,Zanzibar’s director of fisheries,went on state radio to warn the public against eating the dolphins’meat,saying the cause of death had not been found.
The Indo-Pacific bottlenose,commonly known as dolphins,are the most common species in Zanzibar’s coastal waters,with bottlenose and humpback dolphins often found in mixed-species groups.
63.According to the passage,the bottleneck dolphins            
A.a(chǎn)re often attacked by submarine in deep water
B.find it hard to find enough food near the coast
C.often fall ill along the shore of a tourist place
D.1ike living in the deep waters near the coast
64.The underlined word“reorient”means           
A.lose their way                   B.find their way
C.look for food                        D.fight against enemies
65.What can we infer from the passage?
A.The dolphins died because of the sonar from US submarines.
B.The dead dolphins can not be eaten as they are poisonous.
C.The US experts are researching sonar at present.
D.The ability of locating is extremely important for dolphins.
66.What would be the best title for the passage?
A.400 dolphins died along the coast of Nungwi.
B.Dolphins are facing increased risk of death.
C.It’s necessary for us to protect dolphins.
D.Nungwi is famous for many dolphins there.

A new study in West Africa shows how farm irrigationsystems powered by the sun can pro-duce more food and money for villagers. The study-in Benin found that solar - powered pumpsare effective in 8upplying water, especially during the long dry season.
Sub - Saharan Africa is the part of the world with the least food security. The United Na-tions Food and Agriculture Organization estimates that more"than one biillion of the world' s peo-ple faced hunger last year.Around 265 million of them live'south of the Sahara Desert:  Lack of  rainfallis one oftheir main causes offood shortages..
Jennifer Bumey from Stanford University in Califomia led the study.The research team helped build three solar - powered drip irrigation -(滴灌) ,systems in northem Benin. Between 30 and 35 women used each system to pump water from the ground or a stream.Each woman was responsible for farming her own 120 sqrurre meters of land. They also farmed other land  collectively.
The solar - powered irrigation systems produced an average of nearly two tons of vegetables per montb. During the first year, the women.kept a monthly average of almost rune kilograms of vegetables for home use.They sold the surplus produce at local markets. The eamings greatly increased their ability to buy food during the dry season which can last six to nine months. Peo- ple in the'two villages with the systems were able to eat three to five more servingsof yegetables per day.But making the surplus available at markets also had a wider effect.
The study compared the villages with two others where women farmed with traditional methods like carrying water in buckets. The amount of vegetables eaten in those villages also  increased, though not as much.The researchers note that only four percent of the croplamd in sub - Saharan Africa is irrigated. Using solar power to pump water has higher costs at first. But    the study says it can be more economical in the long term than using fuels like gasoline,  diesel  or kerosene. And solar power is environmentally friendly.
66.Food security in Sub - Saharan Africa is insufficient mainly because of
A.lack of rainfall         B.limitation of farmland
C. a small crop variety   D.little sunlight
67.From the third paragraph we know that _______.
A.water is wasted by using the system
B. the farmers imgate the land together
C. all farmers use irrigation systems in northem Benin
D. the solar - powered systems take up more manpower
68.The underlined word "surplus" in the 4th paragraph most probably means_______
A.special             B.unnecessary      C.extra      D.a(chǎn)bandoned
69.Usinf.solar power to pump water has advantages EXCEPT that
A.solar energy has higher cost at first
B.solar power helps to protect environment
C.solar power helps farmers increase eanungs
D. solar energy can be more economical in the long run
70.What can be the best title for the text?
A.Manpower affects rainfallin Africa
B.Irrigation by carrying water in buckets
C.Solar - powered pumps aid African farmers
D.Vegetable supply increased in African villages

Could we "terraform" Mars —that is, change its frozen, thin-aired surface into something more friendly and Earthlike? Should we? The first question has a clear answer: Yes, we probably could.Spacecraft, including the ones now exploring Mars, have found evidence that it was warm in its youth, with rivers flowing into vast seas.And right here on Earth, we've learned how to warm a planet: just add greenhouse gases to its atmosphere.Much of the CO2 that once warmed Mars is probably still there, in frozen dirt and polar ice caps, and so is the water.
Most of the work in terraforming, says NASA scientist Chris Mackay, would be done by life itself. "You don't build Mars," Mackay says."You just warm it up and throw some seeds." Powerful greenhouse gases could be produced from elements in dirt and air on Mars and blown into the atmosphere; by warming the planet, they would release the frozen CO2, which would quicken the warming and increase atmospheric pressure to the point where liquid water could flow.Meanwhile, says botanist James Graham of the University of Wisconsin, human settlers could seed the red rock with a succession (系列) of ecosystems ?first bacteria and lichens (地衣), which survive in Antarctica, later mosses (苔蘚), and after one thousand years or so, redwoods.Getting breathable oxygen levels out of those forests, though, could take thousands of years.
However, Mars is in no immediate danger.Some space scientists recently recommended going to the moon or an asteroid (小行星) first, and pointed out the space agency lacks the funds to go anywhere.It didn't estimate the cost of gardening a dead planet.
72.What is the most essential to make Mars fit for living?
A.Turn ice into flowing water.          B.Clean the dirty atmosphere.
C.Make the atmosphere more suitable.    D.Go to the moon or an asteroid first.
73.What does the author think of the idea ofterraforming Mars?
A.We could do it.                            B.We couldn't do it.
C.We should do it.                           D.We shouldn't do it.
74.In the botanist's opinion, man needs to __________.
A.enable Mars to clean its atmosphere
B.build a greenhouse on Mars
C.send some people to settle on Mars
D.cultivate ecosystems from lower to higher life form
75.What is the best title for the passage?
A.Making Mars the New Earth.           B.A Good Way to Change the Universe
C.Humans' Great Power.                     D.Terrible Science and Technology.

 A new study has found no evidence that sunscreen, commonly used to reduce the risk of skin cancer, actually increases the risk.
 Research from the University of Iowa based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanoma (黑素瘤). They said that they found flaws in studies that had reported associations between sunscreen use and higher risk of melanoma.
 Most health experts believe that by protecting the skin from the harmful effects of the sun, sunscreen helps prevent skin cancer, which is increasing in incidence (發(fā)生率) faster than any other cancer in the United States.
 But questions have been raised about sunscreen and whether it may have the opposite effect by allowing people to remain exposed to the sun longer without burning.
 The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancer---are more likely to use sunscreen. As a result, it may appear that sunscreen users get cancer more often.
 The studies, which generally relied on volunteers to recall their sunscreen use, were also unable to prove how well the products had been applied, said the new study.
60.The underlined word “flaws” in the 2nd paragraph most probably means _________.
A.evidences         B.facts         C.faults         D.failures
61.People with fair skin and freckles ________.
A.seldom use sunscreen               B.a(chǎn)re more in danger of skin cancer
C.can be free from the harm of the sun       D.often expose themselves to the sun
62.We can learn from the passage that _________.
A.sunscreen users get skin cancer more often
B.the volunteers have proved the effect of the sunscreen
C.the new study has based on the experiences of volunteers
D.the number of skin cancer patients is increasing in America
63.Which of the following is the best title of the passage?
A.Sunscreen to Prevent Skin Cancer       B.Sunscreen to Increase Skin Cancer
C.Skin Cancer Caused by Sunscreen       D.Skin Cancer Caused by Freckles

You’ve probably heard of the butterfly effect that small changes in one place can lead to great damage elsewhere. The Toy Story II, Made-in-China, appearing on the internet, TV screens and front pages of newspapers worldwide since August, was a live show. China’s fame as “the world’s factory” was badly damaged this summer by a small, but powerful magnet (磁鐵), and colorful paints on toys.
Mattel, the world’s largest toy company in the US, on August 14 announced the biggest recall (召回) of toys in its history. Among the recalled products were 17.4 million toys that had a design problem. They contained a small, powerful magnet that could harm children if it was swallowed. Another 2.2 million toys were recalled because of impermissible levels of lead (鉛) in their paint.
Although the designing problem has nothing to do with where the toys were made, the reports in the western media of the recall started to draw a horrible picture in many American parent’s minds.
The toy recall issue followed shortly after recalls earlier in the year of Chinese-made pet food and toothpaste and left users all over the world worried about buying anything labeled (貼上標(biāo)簽) “Made-in-China”.
The recall of the toys teaches Chinese companies that quality is extremely important. However, many of the complaints by western countries about Chinese goods reflect complicated feelings about the growing Chinese economy, culture differences and various political systems.
However, more than 100 US multinational companies from many industries, including Boeing and Microsoft, signed a letter to the US Congress on September 28, to say no to the proposal against China. “Imposing (加強(qiáng)) unfair barriers to trade in the name of product safety is not a solution,” the companies wrote.
Toys are made for children to learn about the reality world and become more mature (成熟), however, the Chinese version of Toy Story helps lots of adults learn about responsibility, importance of quality, understanding, communications, and more.
53. The author mentions the butterfly effect at the beginning of the passage to ______.
A. explain what the butterfly effect is
B. tell the readers what causes the butterfly effect
C. say that the toy effect is similar to the butterfly effect
D. compare the differences between the butterfly effect and the toy effect
54. Which of the following are the reasons mentioned to have caused the recall?
a. The picture on the toys.
b. The designing problem.
c. The colorful paints on toys.
d. The materials toys are made of.
e. The small powerful magnet on toys.
A. abe                   B. bde                   C. bce                   D. acd
55. Boeing and Microsoft signed a letter to the US Congress because ______.
A. the growing Chinese economy makes them afraid
B. the Chinese companies have realized the importance of quality
C. the Toy Story has made some Chinese companies suffer great losses
D. they think it’s unfair to impose barriers in the name of product safety
56. Which of the following can be the best title of the passage?

A
Experts around Europe are discussing the embarrassing museum safety following the theft of two art masterpiece paintings on Sunday. A large hunt got under way Monday for thieves who walked into a lightly guarded museum in Oslo, Norway, tore two paintings off the wall and ran away.
Some expressed fear that works of art are in increasing danger from violent robbery — unless, said Deputy Culture Minister Yngve Slettholm, "we lock them in a mountain bunker(碉堡)."
Armed, masked robbers stole the Edvard Munch masterpiece "The Scream" and another of Munch's works, "Madonna," from Oslo's Munch Museum on Sunday as visitors watched in disbelief.
The purpose behind the robbery also remained unknown. But art experts guessed the thieves were either looking for money or wished to impress other criminals since it would be nearly impossible to sell such famous pieces of art.
This is the second time in a decade that a version of the painting has been stolen. Another version of "The Scream" was stolen from Oslo's National Gallery in February 2004, but recovered three months later. The Munch works were not insured against theft, because it was impossible to set a price on them, said John Oeyaas, managing director of Oslo Forsikring, the city-owned company that insured the paintings against damage. But he said the theft in broad daylight from one of Norway's most visited museums raises the question of security — "How can we make these artworks available to the public while still ensuring their safety?"
56. The stolen paintings were drawn by ______.
A. Oslo Forsikring        B. Yngve Slettholm              C. Edvard Munch          D. John Oeyaas
57.Which of the following description is correct about the theft?
A.The two paintings were stolen on Monday
B.Visitors to the museum saw the faces of the robbers
C.The thieves were looking for money
D.The thieves had weapons with them during the theft
58. The Oslo’s Munch Museum ______.
A.is one of the most popular museum in the country
B.had all its paintings insured against theft
C.were going to lock the paintings in a mountain bunker
D.had another version of “The Scream” stolen in 2004
59. What could be the best title for this passage?
A.Dangers of Violent Robbery
B.How to Ensure Safety of Artworks
C.Priceless Art Lost in Bold Theft
D.Famous Art Works Favored by Thieves

D
A sunflower is a sunflower . A mobile phone is a mobile phone . But can you combine the two to do something for your local environment?
As early as next year it may well be possible. When you have finished with your mobile phone you will be able to bury it in the garden or a plant pot and wait for it to flower. A biodegradable (能進(jìn)行生物遞降分解的) mobile phone was, this month, introduced by scientists.
Scientists have come up with a new material over the last five years. It looks like any other plastic and can be hard or soft, and able to change shape. Overtime it can also break down into the soil without giving out any toxic chemicals. British researchers used the new material to develop a phone cover that contains a sunflower seed. When this new type of cover turns into waste, it forms nitrates (硝酸鉀). These feed the seed and help the flower grow. Engineers have designed a small transparent window to hold the seed. They have made sure it only grows when the phone is thrown away. "We've only put sunflower seeds into the covers so far. But we are working with plant experts to find out which flowers would perform best. Maybe we could put roses in next time," said one scientist.
As phone technology is developing so quickly people are constantly  throwing their mobiles away. This means manufacturers are under pressure to find ways of recycling them. Some 650 million mobile phones have been sold this year. Most of them will be thrown away within two years, adding plastic, heavy metal and chemical waste to the environment. A biodegradable cover can offer some relief for nature, according to the scientists. "The seed is released and the flower grows in the pot so you don't have to concern yourself with the phone when you have finished using it," said Kerry Kirwan. She leads the research team, which is based at the University of Warwick in Britain.
67. The main idea of the passage is ________ .
A. the relationship between high tech and environment
B. the phone technology is developing
C. how to grow sunflowers
D. mobile phone and environment
68. The purpose of introducing a biodegradable mobile phone is ______ .
A. to encourage consumers to recycle
B. to prevent consumers from throwing their phones away
C. to meet consumers’ need
D. to help consumers know which flower can best perform
69. What is the possible meaning of the underlined word ?
A. pleasant    B. poisonous    C. useful    D. new
70. Which of the following statements is NOT true ?
A.Engineers have designed a small transparent window to hold the rose seed .
B. Mobiles with biodegradable covers can do good to nature .
C.Manufacturers are under pressure to find ways of recycling mobiles .
D. The flower only grows when the phone is thrown away .

D
Jupiter is the largest planet in our solar system. It is also one of the most interesting. It was named after Jupiter, the most important of the Roman gods, and nicknamed the “King of Planets.” It is the fifth planet from the sun and the fourth brightest object in the sky. Before the invention of the telescope, Jupiter was thought to be a bright star.
In 1610, the famous astronomer Galileo realised that Jupiter was actually a planet. He also noticed that it had four large moons. These are known as the Galilean moons. The biggest is Ganymede, and it is larger than the planets Pluto and Mercury. Next in size is Callisto, which is the farthest away from Jupiter. It is the closest to the planet, and has a lot of active volcanoes. The smallest of the Galilean moons is Europa. Europa is covered in ice, and scientists believe there may be an ocean underneath.
Galileo's discovery that Jupiter was not a star but a planet was very important. Before this time, people believed the Earth to be the centre of the universe. They thought that the sun, stars, and other planets all revolved around the Earth. However, Galileo proved that the sun was at the centre of the universe!
(A) Jupiter is farther out in the solar system than Earth, so it takes longer to revolve around the sun. (B) However, a day on Jupiter is much shorter, only 9.8 Earth hours. (C) This is because it spins(旋轉(zhuǎn)) a lot faster than the Earth does. (D)
Another of Jupiter's interesting features(特性) is its “Great Red Spot.” On the surface of the planet is a large red spot. The spot is actually a huge storm like a hurricane, but bigger. It covers an area twice as big as the Earth and has been going on for at least 400 years!
62. What is the passage mainly about?
A. Features of the planet Jupiter.     
B. Differences between Jupiter and other planets.
C. Galileo's accomplishments in astronomy(天文).
D. How Jupiter moves in the solar system.
63. According to Paragraph 3, why is Galileo's discovery important?
A. Because Jupiter was thought to be smaller than Earth.
B. Because people knew that Earth is not the only planet.
C. Because it meant that the planet goes around the Earth.
D. Because it proved that Earth is not the centre of the universe.
64. The underlined word “revolved” in the third paragraph is closest in meaning to           .
A. approached        B. stopped            C. sped up            D. circled
65. Where would the following sentence best fit into Paragraph 4, (A), (B), (C) or (D)?
This means that one year on Jupiter is as long as 11.6 Earth years.

There were times when it was only schoolchildren who felt sick before they got their grades.But now teachers in Germany are scared, too, as they are being graded by their students.
Many teachers are opposed to it.They don’t mind being evaluated.But they are upset because the results are then being posted on the Internet and accessible to millions of Internet users.On the website www. spickmich.de during the past four months students have posted evaluations of 100,000 teachers.
The teachers are graded on categories such as “motivated”, “good instruction,” “easy examinations”, or even “sexy.” Many teachers think that their privacy has been violated.
The creators of the website say that the students are only being offered the chance to provide teachers with some feedback about their classroom instruction.Bernd Dicks, who founded the website with three friends, says that the students are largely quite satisfied with their teachers.On a grading scale of one to six, the teachers’ average grade is 2.7 and it has been improving lately.He often says the impression is that students are bullying(欺負(fù)) their teachers.But there is also bullying of the students by teachers.  
“Teachers must also learn to live with criticism,” he added.But still, the website is not totally immune from manipulation(操縱), as one teacher near the northern city of Hanover recently proved.He registered himself on the website as a student and then rated his own teaching colleagues highly.Within a few days, seven of his colleagues were listed in the top 10 rankings of Germany’s best teachers.
45. Many teachers are opposed to the website because        .
A.their privacy has been violated         B.they are afraid of being assessed
C.their evaluations are unfair       D.the results are not satisfying
46.The founders of the website intended to         .
A.get the students to know their teachers better
B.conduct a survey on teachers’ performances
C.help the teachers to improve their teaching
D.change the teachers’ ways of giving instructions
47.From what the teacher in Hanover did, we can infer         .
A.he intended to help his colleagues
B.there was some disadvantage of the website
C.his colleagues were more popular than him
D.he wanted to know how he was evaluated
48.Which of the following can be the best title of the passage?
A.Teachers get graded by pupils  B.Teachers are angry with website
C.Teachers need self-assessment        D.New invention in assessing teachers
