We’ve all heard the saying “Go Green”, but is it important? Can one person really make any difference? These may all be questions you’re asking yourself.
Our main source of energy, at the moment, is fossil fuels. We’ve been using fossil fuels for decades now, so why stop? You see, fossil fuels are created over time by the earth, and can only be replaced over time by the earth, but we were using them faster than the earth could produce them. On top of stripping(剝奪)the earth of her natural resources, we’re also damaging the atmosphere by burning things like coal, oil, and natural gases. That’s the greenhouse effect, which occurs when the burning of these fossil fuels help trap the sun’s energy inside the earth’s atmosphere, causing the temperature to rise over time.
With all the people in the world, how could you possibly make a difference? Well, here are a few things to think about.
How many lights do you use in your house?
How many miles do you drive to work?
How many electronics do you use, which you don’t need?
If you were to stop and think about it, you’re able to make a bigger difference than you might realize.
So many times you’ll hear people say, “So what? I won’t be around for it when things go bad.” But bad times are coming quicker than you might like to believe. It’ll be you children, or maybe even your grandchildren. With the temperature ever-rising, the polar ice caps are melting and water begins taking over land, so many people will crowd into so little space.
As you can see, this is no laughing matter. It’s time to take action. Don’t let your children or grandchildren live in a world without hope. One person at a time, we can begin to save this earth.
60. The passage is mainly to _______.
A. introduce what “Go Green is”
B. call on us to “Go Green”

The scene in the Hollywood movie The Day After Tomorrow, where global warming could soon turn the global climate (氣候) into a new ice age, may never occur, according to new research.
The next ice age could be 15,000 years away, say European scientists who last month announced a continuous record of 7.40,000 years of climate data (數(shù)據(jù)) obtained from the Antarctic ice.                         
Scientists from 10 nations have now almost completely drilled through a 3,000-meter.depth of ice high in the Antarctic mainland. They figure out that the area where summer temperatures can fall to –40℃, has at least 900,000 years of snowfalls,, kept as neatly as the growth rings of a tree. And the ice and air caught in each layer(層) have begun to answer questions about the climates in the past..
The results show that there have been eight ice ages in the past 740, 000 years and eight warmer periods. And by comparing the pattern of global conditions today with those of the past, the researchers reported in Nature that the present warm period could last another 15, 000 years.
Research suggests that there is a very close connection between greenhouse gas levels and global average temperatures. It also shows that carbon dioxide (二氧化碳) levels are the highest for at least 440,000 years.         
"If people say to you: the greenhouse effect is a good thing because we would go into an ice age otherwise, our data say no, a new ice age is not hanging over our heads,” said Eric Wolff from the British Antarctic Survey. "Now we have eight examples of how the climate goes in and out of ice ages… and you can learn what the rules are that go into the climate models that tell us about the future."
Scientists found that whenever temperatures rose in the frozen record, so did carbon dioxide level. "In 440,000 years we have never seen greenhouse gas get as thick as it is today," said Dr Wolff.
48. In drilling through the ice in Antarctica, scientists, have found that______.
A. the lowest temperature there is -40℃     B. the depth of ice is 3,000 meters
C. the ice has existed for 15,000 years          D. snowfalls are kept in certain patterns
49. The information of the global climate conditions in the past can be obtained through______.
A. separating carbon dioxide from the air     
B. examining the growth rings of trees
C. comparing temperatures in different areas
D. studying the ice and air caught in each layer
50. We can infer from Eric Wolff's words that_______.
A. there is something wrong with the data     B. greenhouse effect is always a bad thing
C. a new ice age will not come in the near future
D. greenhouse gas will get thick in the future
51. What would be the best title for the passage?
A. Research over the Antarctic area.                    B. Warm period to last about 15, 000 years.
C. Report on the eight ice ages in the past.    D. Hollywood movies and the global climate.

A
We bet that on cold wintry days, many of you love to stay in your warm home and, every now and then, come out into the kitchen for a snack. Unfortunately, plenty of creepy-crawly critters(爬行生物) like to do the same thing!
Winter is the time when bugs (蟲(chóng)子) invade your house without an invitation. The season can be tough for such creatures. In winter the air is cold, the ground is hard and many trees have no leaves. So bugs do what they have to do to survive.
Monarch butterflies head south to warmer climates. Ants crowd in deep underground colonies and eat food they have been storing all year. Many insects go into a deep sleep called diapause. There’re different kinds of diapause, but all are similar to hibernation, a time when bigger animals become inactive in the cold. Insects go into an inactive period, too, but it often isn’t when the temperature drops.
They rely on more dependable signals in the environment. For example, many insects can tell how much sunlight there’s each day. They use that to tell them when to shut down. Bugs are cold-blooded, meaning that their inside temperature is the same as the outside. They can’t move much when it gets below 40 degrees Fahrenheit. So they search for any warm place.
They’re looking for protection. These guys have been doing this for 300 million years, so they don’t really know they’re coming into your house. The home is a recent event in terms of their evolutionary behavior. They enter through tiny cracks or come in unnoticed on your clothes or shoes. Remember that they may be invading your homes for warmth and food, but they don’t care about humans.
56. What is the purpose of the first paragraph?
A. To point out that humans like to stay at home in winter.
B. To mean that humans and bugs have the same living habits.
C. To mean that bugs will invade the house for their winter.
D. To put forward the idea that bugs are not welcome in winter.
57. According to the text, what is diapause?
A. It is the same as the animals’ hibernation.
B. It often appears in warm areas all the year.
C. It is done to keep bugs active in winter.
D. It is a deep sleep similar to hibernation.
58. What often decides bugs’ diapause?
A. The lower local temperatures.           B. The amounts of sunlight.
C. Kinds of environmental signals.         D. The insects’ inside temperature.
59. According to the text, bugs invade humans’ homes to ______.
A. attack humans                                 B. look for enough food
C. seek for protection                           D. show their evolutionary results
60. What would be the best title for the text?
A. Bugs’ life on cold wintry days
B. Why bugs invade your home in winter?
C. Good relations between humans and bugs
D. What does diapause mean?

A
The luxury of eating an apple on Mars could cost as much as US $22,000. That's because it costs about US $120,000 to launch a kilogram of anything into deep space. So getting enough food into orbit is a big problem facing astronauts on a trip to Mars.
After NASA (National Aeronautics and Space Administration) has no current plans to send astronauts to Mars, related research is being carried out—including the production of food. Astronauts on the international Space Station usually eat primarily freeze-dried food to which they add water. However, the weight of the packaging—almost as much as the food inside—costs a lot of money. The biggest problem of all is a psychological one.
Scientists believe that astronauts will suffer without the variety offered by fresh vegetables. The answer is to grow at least some of the food. On a short trip it is imagined that astronauts will eat vegetables such as lettuce, spinach and carrots grown in a refrigerator-sized unit known as a "salad machine". On longer journeys they will actually grow vegetables in greenhouses on Mars. Martian astronauts will eat a vegetarian diet since it will not be practical to raise animals. To make up for the lack of meat, recipes have been created to add as much variety to the diet as possible, using only a basic number of products. It uses heat and mechanical force to transform soybeans into meat and cheese substitutes(代替品). The prized result of this research is a purely vegetable-based pizza with meat and cheese substitutes .
41. What is the best title for this story?
A. Space Food                                          B. Astronauts' Problem
C. The Packaging of Space Food          D. Mars Rover-Spirit
42. What is the main problem with the diet of astronauts on the international Space Station now?
A. The packaging is too expensive.
B. Only fresh vegetables are offered.
C. Too much water is needed for dried food.
D. There are not enough choices of food.
43. What is the "salad machine" in the spaceship for?
A. It stores vegetables.                 B. It grows vegetables.
C. It cooks green salad.                D. It mixes green salad.

B
 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

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
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 .

Monarch butterflies(黑脈金斑蝶)are a common summer sight in the northern United States and Canada . These large orange and black insects(昆蟲(chóng))brighten parks and gardens as they fly lightly among the flowers . What makes monarchs particularly interesting is that they migrate(遷飛)—all the way to California or Mexico and back . They are thought to be the only insect that does this.
Every year in the late summer monarchs begin their journey to the south. Those heading for Mexico go first for the Louisiana-Mississippi area, then fly across the Gulf of Mexico into Texas. Once in Mexico, they settle themselves in one of about fifteen places in a mountain forest filled with fir trees. Each place provides a winter home for millions of monarchs. The butterflies are so many that they often cover entire trees. When spring comes, they begin their long journey north. 
The question is often asked whether every butterfly makes the round-trip journey every year. And the answer is no. The average monarch lives about nine months. So one flying north might lay eggs in Louisiana and then die. The eggs of that generation may be found in Kentucky; the eggs of the next generation may end up in Wisconsin or Michigan. The last generation of the season, about the fourth , will make their way back to Mexico and restart the journey.
Scientists learn about monarchs’ migration by catching and making marks on the insects. By recatching a monarch with such a mark and noticing where it came from , the next scientist can get to know things like the butterfly’s age and its routing(路線).
64. One of the places where monarchs spend the winter is       .
A. the Gulf of Mexico                 B. an area in Mississippi
C. a forest in Mexico                D. a plain in Texas
65. The routing of monarchs’ migration can be learned       .
A. by collecting their eggs in the mountains
B. by examining the marks made on them
C. by comparing their different ages
D. by counting the dead ones in the forests
66. What is the subject discussed in the passage?
A. Life and death of monarchs         B. Scientists’ interest in monarchs.
C. Winter home of monarchs.               D. Migration of monarchs.

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.
