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[来源:学*科*网]
50. According to the passage, which of the following statements is TRUE?
A. None of the researches done by scientists is right.
B. Scientists sometimes may make mistakes in their work.
C. The color of the universe is light greenish.
D. Mark Fairchild apologized for his mistake about the color of universe.

Nothing says love like a dozen long – stemmed roses on Valentine’s Day. More than a million roses will be sold during this festival for lovers, the biggest day of the year for the nation’s rose industry. It’s going to remain the most popular flower because love never goes out of style.

Yes, a rose is a rose is a rose. But selling them is no longer a beautiful experience for traditional flower shops. Supermarkets now offer convenience to the busy and discount rose shops help those hopelessly in love save money. Roses only is a good example of a discount rose retailer that was transformed from a traditional shop to answer the challenge in the’ 90s.

Inside this store on Sixth Avenue near 40 th Street, contemporary white furniture and wall – to – wall mirrors give it an expensive look. Customers move about freely among the counters, looking eagerly at the roses in more than 50 colors from shelf to shelf. Some customers say it’s the high quality of the roses that attracts them there. “I spent $ 20 but the flowers looked like I paid 60 or 70 dollars,” says one customer.

Studies show more people are buying roses in ones, two and threes these days. In fact, more than half of all roses are sold in bunches of fewer than a dozen. But Roses Only's low prices encourage people to spend. Even on Valentine's Day, when the price of a dozen roses and delivery can soar as high as $150, 12 of Roses Only's most expensive flowers sell for just $35. The company's key to success is to hold prices down by controlling every link in the rose chain. It grows its own roses in the sunshine of the Andes Mountains. In addition, the company also sells other items such as ballons and stuffed animals.    

       While discount rose retailers are witnessing their business bloom, U.S. rose growers aren’t able to compete with the fierce foreign competition. More than 57% of roses sold in the USA are grown in other countries. The biggest foreign producers are Colombia and Ecuador, which accounted for almost 90% of the total imported last year. The trend has hurt domestic rose growers such as Johnson Flowers of California, considered to be this country's leading producer.

Now, instead of fighting overseas rivals, the Johnsons are trying to work with them. "We have a few big fighting overseas rivals, the Johnsons are trying to work with them. “We may also widen our business to include the service area and be a representative for overseas flower producers.”

       As a result of severe competition, those in the rose business long for the good old days, whereas ordinary people benefit from the low price.

60.What is the central theme of this text?

A.The US rose business is going from bad to worse in spite of the efforts made.

B.The rose will remain the most popular flower as love never goes out of date.

C.The rose business is trying to meet the challenges in the market to succeed.

D.The rose industry plays an important role in American economy.

61.How does Roses Only obtain success in the discount rose retailing field?

       A.By setting up more chain stores across the country.

B.By selling roses in supermarkets.

C.By selling high quality roses at a low price.

D.By selling roses by the dozen.

How old is “old”?  The answer has changed over the years. Two hundred years ago,you were old at 35.At the beginning of the 20 th century,the average life span(平均寿命)was 45. In 1950,70-year-olds were really old.Today,a healthy 70-year-old is still thought young.

第二部分:阅读理解(第一节20小题,第二节5小题;每小题2分,满分50分)

第一节:阅读下列短文, 从每题所给的四个选项 (A、B、C和D) 中, 选出最佳选项。

Being interested in a theme park since the time that I was a child, I have learned a thing or two over the years about packing for a day of fun. A trip to a theme park is always a adventure, but if you’re not prepared, your day of fun could easily turn into a tiny little nightmare(噩梦). It is important to pack long sleeved(带袖的) shirts or jackets for all members of your family. I is also a good idea to pack an extra pair of socks for each member of the family, especially the children, as those wonderful water rides can be fun, but wet socks that won’t dry aren’t so much fun.

You don’t want to pack too much food, as you will probably want to experience at least some of the food offered at the theme park of your choice(that’s half of the fun), but it’s always a good idea to bring some energy increasing snacks, such as fruit,trail mix,etc. This can mean the difference between spending a lot of money on snacks or a little money on one or two good meals.

Theme parks,while fun and exciting, can wear a person out,especially a child, so it’s important to keep hydrated(含水的). I would suggest packing one bottle of water per person, and possibly a couple of cans of soda or bottles of juice as well.

It’s a good idea to have at least two cell phones or even a set of “walkie-talkies” in the event that your family gets,separated in the park. It’s a good idea to give one of these things to the children and one to the parents and make sure that each of them knows how to use it. This could be the difference between trouble and a happy ending,

1.You should get well prepared before going to a theme park__________.

  A. because the trip always costs much money

B.because there are always too many people in a theme park.

C. so as not to suffer from bad dreams when going back

D.so as to cut down your trip expenses and have more fun

2.From the passage, we can know_______________.

  A.the author was fond of visiting theme parks when he was a child

B.wearing wet socks in a theme park will bring children much fun

C.it is terrible to have a taste of the food offered in a theme park.

D. we’d better bring enough food, clothing and water when going to a theme park

3.What does th underlined part”walkie-talkies” in the last paragraph probably refer to?

  A. A kind of transportation tool           B.A kind of musical instrument

C.A kind of CDplayer                  D.A kind of phone

4.How many types of things does the author advise us to pack for day trips to a theme park?

  A Three         B.Five      C.Six      D. Eight

 

A team from Krakow, in Poland, used functional magnetic resonance imaging (机能性核共振成像)(FMRI)to assess brain activity when 40 volunteers were shown various images.Men showed activity in areas which dealt with what action they should take in order to avoid or face up to danger.But the study found more activity in the emotional centers of women's brains.The researchers, from another university, carried out scans on 21 men and 19 women.Brain activity was monitored while the volunteers were shown images of objects and images from ordinary life designed to remind different emotional states.

The images were displayed in two runs.For the first run, only negative pictures were shown.For the second run, only positive pictures were shown.

While viewing the negative images, women showed stronger and broader activity in the left thalamus(神经床).This is an area which passes sense information to the pain and pleasure centres of the brain.Men showed more activity in an area of the brain called the left insula(脑岛), which plays a key role in controlling natural functions, including breath, heart rate and digestion.Generally, activity in this area tells the body to either run away from danger, or meet it head on - the so-called "fight or flight response".

While viewing positive images, women showed stronger activity in an area of the brain associated with memory.With men, the stronger activity was recorded in an area associated with visual processing.Dr Urbanik believes these differences suggest women may analyze positive stimuli(刺激)in a broader social context and associate positive images with a particular memory.

For instance, viewing a picture of a smiling child might remind memories of a woman's own child at this age.On the contrary, male responses tend to be less emotional.

1.The research shows that men response differently to__________compared with women.

A.different images    B.ordinary life 

C.different activities        D.medical scan

2.According to the passage, when faced with danger, ____________.

A.women react more slowly than men       B.women usually try to avoid it 

C.men usually have no reaction         D.men react to it more directly

3.What is discussed in the 4 th paragraph?         .

A.Men and women’s different memories   B.The different responses to the children

C.Different reactions to positive stimuli    D.Negative results of the visual processing

3.The passage mainly develops______.

A.by inferring                   B.by comparing  

C.by listing examples       D.by giving explanations
