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 making a mistake. They said their finding was much more colorful than it should have been. They now say the light from our universe is closer to white. It is more like a milky or creamy white color.
The scientists gave a number to each of the colors of the different star systems. Then they added the numbers together and found the average measurement. The scientists used this average to identify the color of the universe. They said it was a very pretty light green or turquoise color. They called it “cosmic (宇宙的) spectrum (光谱) green.” Many newspapers and television stations reported their finding.
Other scientists and color engineers attempted to reproduce the result. Mark Fairchild of the Rochester Institute of Technology in New York was the first person to identify a mistake. He discovered a mistake in the computer software program used by the Johns Hopkins scientists.
When the mistake was corrected, the results changed. The new color of the universe is much less colorful. It is very close to white. The scientists apologized for the mistake. They are now working with the Rochester Institute of Technology to produce more images regarding the color of the universe.
48. Why did the scientists do the research?
A. They wanted to win a Nobel Prize. B. It’s required by the government.
C. They did it just for fun. D. It’s part of their research.
49. We can infer that the passage was probably written in _______.
A. January B. February C. May D. March
50. According to the passage, which of the following statements is TRUE?
A. None of the researches done by scientists is right.

Scientists say the warming of the Earth’s atmosphere has begun to affect plant and animal life a
round the world. Scientists from the University of Hanover in Germany reported their findings in Nature. They say global warming is affecting endangered species, sea life, and the change in seasonal activities of organisms. Global warming is caused by carbon dioxide and other heat-trapping gases in the atmosphere.
Studies show that the Earth’s climate has warmed by about six tenths of one degree Celsius during the past one hundred years. Most of the increase has taken place in the last thirty years. German scientists have studied different animal and plant population around the world during the past thirty years. They say some species will disappear because they cannot move to new areas when their home climate gets too warm.
The scientists say one of the biggest signs of climate change has been the worldwide decrease in coral reefs. Rising temperatures in the world’s warm ocean waters have caused coral to lose color and die. In the coldest areas of the world, winter freezing periods are now happening later and ending earlier. Researchers say these changes are having severe effects on animals such as penguins, seals, and polar bears.
Changes in temperature and wetness in the air can also affect the reproduction (繁殖) of some reptiles(爬行动物) and amphibians(两栖动物). For example, the sex of baby turtles is linked to the average temperature in July. Scientists say even small temperature increases can threaten the production of male turtles.
In Europe, scientists say warmer temperatures are affecting the spring and autumn seasons. This is affecting the growth of plants and delaying the flight of birds from one place to another.
Scientists are concerned about invasions of warm weather species into traditionally colder areas. Rising temperature has been linked with the spread of diseases in areas such as Asia, East Africa, and Latin America.

Recently a Beijing father sent in a question at an Internet forum (论坛) asking what "PK" meant. "My family has been watching the 'Super Girl' singing competition TV program. My little daughter asked me what 'PK' meant, but I had no idea," explained the puzzled father.
To a lot of Chinese young people who have been playing games online, it is impossible not to know this term. In such Internet games, "PK" is short for "Player Kill", in which two players fight until one ends the life of the other.
In the case of the "Super Girl" singing competition, "PK" was used to refer to the stage where two singers have to compete with each other for only one chance to go up in competition ranking.
Like this father, Chinese teachers at high schools have also been finding their students' compositions using Internet jargons (行话) which are difficult to understand. A high school teacher from Tianjin asked her students to write compositions with simple language, but they came up with a lot of Internet jargons that she didn't understand.
"My 'GG' came back this summer from college. He told me I've grown up to be a 'PLMM'. He always took me to the 'KPM'," went one composition.
"GG" means Ge Ge (Chinese pinyin for brother). "PLMM" refers to Piao Liang Mei Mei (beautiful girl). "KPM" is short for KFC, Pizza Hut and McDonald's.
Some specialists welcome Internet jargons as a new development in language. If you do not even know what a Kong Long (dinosaur, referring to an ugly looking female) or a Qing Wa (frog, referring to an ugly looking male) is, you will possibly be regarded as a Cai Niao!
40. By writing the article, the writer tries to ________.
A. expose some Internet languageB. suggest common Internet language
C. laugh at the Beijing father D. draw our attention to Internet language
41. What does the writer think about the term "PK"?
A. Fathers can't possibly know it. B. The daughter should understand it.
C. Online game players may know it. D. "Super Girl" shouldn't have used it.
42. The examples of the Beijing father and the Tianjin teacher are used to show
that Internet jargons________.
A. are used not only online B. can be understood very well
C. are welcomed by all the people D. cause trouble to our mother tongue
43. What would be the best title for the passage?
A. A puzzled father B. Do you speak Internet-ish?
C. Keep away from Internet-ish D. Kong Long or Qing Wa?

第一节：阅读下列文章,根据文章内容,从文后所给的A、B、C、D四个选项中选出最佳答案。
Last year my wife and I spent a most interesting month in Turkey. Before we left, we were reminded of the difficulties of driving in Turkey. We certainly did not find this to be the case and, except for a few places in faraway mountain areas, the roads were wide, and well-paved (铺). We drove for 12 days along the Western Coast of Turkey and had no problems at all. We found the Turkish drivers most polite and well educated. We also found that eating lunch in the smaller towns was difficult so we picnicked almost every day.
The following day after our arrival was Turkey’s Children’s Day, started by Mustafa Kemal Ataturk. Ataturk loved children and he often said, “Children are a new beginning of tomorrow”. He even dedicated the day 23rd of April to the children. Today, it is celebrated as Children’s Day as well as the date when the Republic of Turkey was founded.
On that day certain children are picked to take over the places of the government, and a lucky kid will be the president of Turkey for a whole day. He can decide what’s going to happen and whether or not he is going to have the president sit next to him. There are a very large number of things you can do but some shops aren’t open because they are celebrating as well.
All in all, it was a more enjoyable trip. I would recommend a trip to Turkey to anyone with an adventurous spirit!

American researchers say drinking tea may help strengthen the body’s defense system against infection（感染）．Doctors at Brigham and Women’s Hospital in Boston，Massachusetts，did the study．The team studied a chemical found in black，green，oolong and pekoe tea This chemical is an amino acid（氨基酸）called L-theanine．The scientists say it may increase the strength of Gamma delta T cells，which are part of the body’s defenses．
First，the researchers mixed some of these cells with antigens（抗原）found in the amino acid Antigens help the body react to infection．Then the scientists added some bacteria（细菌）．
Within twenty-four hours，the cells produced a lot of interferon，a substance that fights infection Cells not mixed with the antigens did not produce interferon．
In the second part of the study，eleven people drank five to six cups of black tea every day．Ten other people drank the same amount of instant coffee．That is dried coffee mixed with hot water．
Two weeks later，and again two weeks after that，the researchers tested the blood of all twenty-one people．They also looked at what happened when they added bacteria to the blood cells．They found that the tea drinkers produced five times more interferon after they started drinking tea The coffee drinkers did not produce interferon．
Doctor Jack Bukowski led the study He says the antigens added to the Gamma delta T cells were responsible for the increased reaction to the bacteria．He says the study also showed that the cells were able to remember the bacteria and fight them again the next time．
Earlier research already has found that tea can help prevent heart disease and cancer Doctor Bukowski says the new study must be repeated with more people．If the findings prove to be true，he says，then tea drinking might also help protect against bacterial infections．He says the amino acid L-theanine could be removed from tea and used as a drug to strengthen the body’s defenses．
73．We may know from the text that can be found in different kinds of tea．
A．Gamma delta T cells B．L-theanine
C．interferon D．bacteria
74．Tea may help strengthen the body’s defense system because it helps．
A．the body to produce more interferon
B．the body to produce more Gamma delta T cells
C．to add some bacteria to the blood cells
D．to mix antigens with some of the cells in the body
75．According to Dr Bukowski，．
A．the findings of the study have already proved to be true
B．he bas taken some amino acid L-theanine from tea and made a drug with it
C．further study is needed to prove the findings true
D．he is not sure whether tea can help prevent heart disease and cancer
