What is the color of the universe? Astronomers did not answer this question until two months ago. This was when two American astronomers reported on their study of all the light in the universe. They said that the universe would appear to the human eye to be a light greenish color, called turquoise(青绿色). Karl Glazebrook and Ivan Baldry of Johns Hopkins University in Baltimore, Maryland, reported their findings in January. They presented research at a meeting of the American Astronomical Society. They said that finding the color of the universe was not part of their more serious scientific research. They did it for fun.
However, earlier this month, the scientists admitted to ma

Fireworks explosions killed many people and injured hundreds more in China as the 2006 traditional Lunar New Year celebrations led to much disorder as well as joy across the nation.
At a temple fair in Henan, 36 people were killed on New Year"s Day when a nearby storeroom full of fireworks exploded. The accident, caused by 3 children who threw burning fireworks into the storeroom, injured up to 48 people.
In the capital, Beijing, where a 12-year ban on Lunar New Year fireworks had just been lifted, the government reported 112 people were treated at hospital emergency rooms over the weekend for fireworks-related injuries.
"On New Year"s Eve alone, we had more than 40 injuries and among them there were around a dozen people with serious injuries," hospital assistant director,Tian Jian said. In China"s south-western city, Chongqing, where the fireworks ban was also lifted after 12 years, firefighters rushed to put out nearly 200 fires caused by fireworks on New Year"s Eve.
A ban on fireworks, which are traditionally believed to ward off evil spirits and ghosts trying to enter New Year, was put in place across 200 cities in China due to safety and environmental pollution concerns. The ban was lifted in Beijing and many other cities in 2006.
However, despite the fireworks disorder, China"s 1.3 billion people were largely enjoying the festival, with celebrations to continue throughout all of this week-long public holiday.

Every Christmas the giant tree in Rockefeller Center sparkles with thousands of lights. From the beginning, when construction workers raised the first one during the depths of the Depression, it has been a symbol of hope. Diana Abad, like most Americans, loved that tree.
In 1999, however, Diana was writing her will. The 33-year-old woman from Staten Island, New York, was diagnosed with leukemia(白血病)and wanted to put her things in order. Doctors told her she had nine months to live.
Her slim chance for survival lay in finding a bone marrow(骨髓)donor. The most likely source for a match is always among relatives -- but her family was tested and there was none.
Then one day in February 2000, she got a call from the hospital saying that out of the four million people enrolled in the National Marrow Donor Program Registry, there was only one match. The potential donor was thinking about it. In March the donor agreed, and the transplant procedure was scheduled for March 27.
On that day, a doctor came in with the marrow in a bag, and Diana remembers him saying: “This is it. If it doesn’t graft within four to six hours, nothing will bring you back.” Diana asked a priest (牧师)to give her last rite(祈祷).
Almost immediately after the two-hour procedure, she felt stronger. Doctors told her it looked like the graft had taken.
Donors are anonymous, but when she was better, Diana sent a note through the Registry: “You don’t know the joy that I am experiencing,” she wrote. “I hope that one day we can meet and I can thank you in person.”
It was several months before the donor replied. At first he didn’t even give his name. He was 34-year-old David Mason, and he lived in Dedham, Massachusetts. But eventually the two exchanged phone numbers and began to talk.
Then unexpectedly and unannounced, he turned up at her door in Englishtown, New Jersey, on December 23. She says it was love at first sight. He says he didn’t feel it until they met the second time.
That meeting began a long-distance romance that culminated(修成正果)under the Christmas tree in Rockefeller Center in December 2004. That’s where David proposed(求婚)to Diana. She, of course, said yes.
64.Which of the following may be the title of the passage?
A.Perfect Match B.Successful Graft
C.Anonymous Donor D.Lucky Christmas Tree
65.What can we know about the Christmas tree in Rockefeller Center?
A.It was planted by the local inhabitants of Rockefeller in the United States.
B.Diana got saved under the Christmas tree and so loved it.
C.Many Americans love the tree because it was raised during the depths of the depression.
D.The tree is very tall and beautifully decorated by people at Christmas time.
66.It can be inferred from the passage that .
A.leukemia is so serious a disease that nobody can survive in America
B.patients who suffer from leukemia may feel very weak
C.bone marrow transplant is very easy to carry out in America
D.the man donor knew Diana would become his wife in advance

TUVALU, a tiny country in the Pacific Ocean, has asked for help as it will be swallowed up by the sea.
Storms and huge waves are a constant threat and none of Tuvalu’s nine little islands is more than five meters above sea level. Salt water is already entering the country’s drinking water supply, as well as damaging plants that produce fruit and vegetable. Without urgent help, the country’s days are numbered.
But Tuvalu is not the first place to face sinking into the sea. Venice, a historic city in Italy best known for its canals, has sunk about 24cm over the past 100 years. Experts say that it will have sunk another 20-50cm by 2050. A century ago, St. Mark’s Square, the lowest point city, flooded about nine times a year. Nowadays, it happens more than 100 times. While Venice is slowly sinking into the mud on which it stands, global warming causes Tuvalu’s rising sea level.
The average global temperature has increased by almost 0.5 centigrade degrees over the past century; scientists expect it rise by extra 1-3 degrees over the next 100 years.
Warmer weather makes glaciers (冰川) melt, and adds more water to the ocean. The warmer temperatures also make water expand, so it takes up more space, causing the sea level to rise. The sea level has risen about 10-25 cm in the last 100 years.
The main cause of global warming is human pollution. Through burning coal, oil and gas, people have been increasing the greenhouse gases in the atmosphere, such as CO2. This adds to the power of the greenhouse effect, making the planet even warmer.
Many scientists believe that, if the warming is not stopped, there will be huge climate changes. The sea level could rise by one meter this century.
Should this come true, the sea will swallow up millions of homes and the world will be flooded with “climate refugees” looking for somewhere to live.
68. We can infer from the second paragraph that .
A. Tuvalu is in danger of being swallowed up by the sea
B. all Tuvalu’s islands are about five meters above the sea level
C. drinking water in Tuvalu has been destroyed
D. Tuvalu is often flooded by storms and waves
69. Put the following events in the right order.
a. Glaciers began to melt. b. People burn coal ,oil and gas.
c. The greenhouse effect is growing. d. The earth is getting warmer and warmer
e. The sea level is rising. f. More CO2 is produced.
g. Many places are sinking into the sea.
A. d,f,b,c,a,e,g B. b,f,c,d,e,a,g C. f,c,b,d,a,e,g D. b,f,c,d,a,e,g
70. What does “climate refugees” mean?
A. Climate changes. B. Climate effect.
C. People forced away from their homeland by climate.
D. Rare animals moving from place to place for climate changes.

A. The sea level has risen about 10-25 cm in the last 100 years for warmer temperatures.
B. The average global temperature has risen by 1-3 centigrade degrees over the past 100 years.
C. The warmer temperature causes the sea level to rise.
D. There will be huge climate changes unless the warming is stopped
The Hollywood Reporter on Friday named Oprah Winfrey the most powerful woman in entertainment on its annual “Power 100 List”.
Winfrey, whose “Oprah” talk show began in national syndication 22 years ago, played a role in the victory of President-elect Barack Obama by praising him early in his run and by supporting him throughout the campaign.
Elizabeth Guider, editor of The Hollywood Reporter, remarked on Winfrey’s “great cultural influence” and said she could be “the most influential woman in America”.
Winfrey, 54, jumped from the No.6 spot on the entertainment trade paper’s 2007 list to No.1 this year. The Hollywood Reporter noted that a study by University of Maryland economists found Winfrey’s support for Obama won him more than l million votes nationwide.

Silence is unnatural to man. He begins life with a cry and ends it in stillness. In between he does all he can to make a noise in the world, and he fears silence more than anything else. Even his conversation is an attempt to prevent a fearful silence. If he is introduced to another person, and a number of pauses occur in the conversation, he regards himself as a failure, a worthless person, and is full of envy of the emptiest-headed chatterbox. He knows that ninety nine percent of human conversation means no more than the buzzing of a fly, but he is anxious to join in the buzz and to prove that he is a man and not a waxwork figure(蜡塑人像).
The aim of conversation is not, for the most part, to communicate ideas; it is to keep up the buzzing sound. There are, it must be admitted, different qualities of buzz; there is even a buzz that is as annoying as the continuous noise made by a mosquito(蚊子). But at a dinner party one would rather be a mosquito than a quiet person. Most buzzing, fortunately, is pleasant to the ear, and some of it is pleasant even to the mind. He would be a foolish man if he waited until he had a wise thought to take pert in the buzzing with his neighbors.
Those who hate to pick up the weather as a conversational opening seem to me not to know the reason why human beings wish to talk. Very few human beings join in a conversation in the hope of learning anything new. Some of them are content if they are merely allowed to go on making a noise into other people’s ears, though they have nothing to tell them except that they have seen two or three new plays or that they had food in a Swiss hotel. At the end of an evening during which they have said nothing meaningful for a long time, they just prove themselves to be successful conversationists.
72. According to the author, people make conversation to _________.
A. exchange ideas B. prove their value
C. achieve success in life D. overcome their fear of silence
73. By “the buzzing of a fly

C. meaningless talks D. the voice of a chatterbox
74. According to the passage, people usually talk to their neighbors _________.
A. about whatever they have prepared B. about whatever they want to
C. in the hope of learning something new D. in the hope of getting on well
75. What is the author’s purpose in writing the passage?
A. To discuss why people like talking about weather
B. To encourage people to join in conversations
C. To persuade people to stop making noises
D. To explain why people keep talking
