 Max Vernon Mathews has been called the father of computer music. He created electronic tools so that people could use computers as musical instruments. He had a huge influence on the development of electronic music and how it is written, recorded and played.

  In 1957 ，Max Mathews wrote the first computer program that enabled a computer to create sound and play it back. At the time,he was working as an engineer at Bell Laboratories in New Jersey. His computer program was called Music. It enabled a large IBM computer to play a sev?enteen-second piece of music that he had written. The computer was so slow that it would have taken an hour to play the piece of music in seventeen seconds. For that reason, Mathews moved the work to a tape player, which could be sped up to play the music at a normal speed. He later said that the sound quality of the musical notes was not great, but the technical importance of the music was huge.

  The science fiction writer Arthur C. Clarke visited Bell Laboratories in the1960s. He heard a computer "sing" the song"Daisy Bell" on devices and programs developed by Max Mathews and other engineers. Clarke noted this technology in his book"2001: A Space Odyssey," which was later made into a movie.

  Max Mathews had a long and productive career. He worked with composers like John Cage and Edgard Varese. He helped create a center for research in computer music in Paris. And he taught at the Center for Computer Research in Music and Acoustics in Stanford University in California.

  Mathews believed modern musicians were not making full use of the power of computer music. He said a violin always sounds like a violin, but with a computer, the way a violin sounds is unlimited. He said he did not want computer sounds to replace live music. But he said he hoped laptop computers would one day be considered serious instruments. 

(   ) 1. Mathews was likely to think that .

     A. the first piece of computer music wasn't music indeed

    B. the first piece of computer music was too short

    C. the IBM computer was fit for creating slow music

    D. the first computer music was of vital technical importance 

(   ) 2. Which of the following is true?

     A. Clarke helped develop computer music.

    B. Mathews became a character in a movie later on.

    C. Computer music was mentioned in Clarke's book.

    D. Clarke saw Mathews operate a singing computer.

(   ) 3. Which of the following words best describes Mathews?

A. Strange.    B. Creative.    C. Outgoing.    D. Curious.

(   ) 4. It is implied in the last paragraph that         .

     A. modern musicians don't understand computer music

    B. a violin does make much better sounds than a computer

    C. a computer can help improve sounds of traditional musical instruments

    D. laptops are more suitable to be used as serious musical instruments

  The venue of the 2012 Summer Olympics was officially awarded to London during the 117th IOS Session in Singapore on July 6,2005. Since then,London has been up to its neck in preparing for the games.

  London has a lot to be excited about being the next Olympic venue requires a major eco?nomic development in terms of tourism and infrastructure(基礎(chǔ)設(shè)施) development as well as job generation and transportation systems expansion.

  Indeed, as early as 2004, plans for the Olympic Park were already known as part of London's bid. Standing on a 500-acre property specifically for the games, the Olympic Park will have a hockey centre，a handball arena，a water polo arena，a basketball arena and the Olympic Stadium, where the opening and closing ceremonies will be held.

  It is expected that the Olympic Stadium alone would be a major attraction in itself,as it is designed to seat up to 80,000 spectators from all around the world.

  Although construction is still on-going，the improved Greenway walking and cycle paths provide an ideal advantage point for curious tourists to see much of the park.

  Along with the Olympic Park,Westfield Stratford City shopping center is also being devel?oped as part of the overall blueprint of the infrastructure preparations for the 2012 Olympics.

  It is said one of the factors that won London its bid is its plans of modernising its transport system. Public transport in London will be expanded.

  To directly transport commuters(月票乘客) from St. Pancras International to the Olympic Park,a high speed shuttle train will be put up. And of course, London minicabs will be as read-y as ever to serve.

Almost half a million tourists，athletes，and spectators are expected to come for the Olym?pics. This is a huge opportunity for generating both private and public income before, during and even after the games. There is no doubt the legacy of the Olympic Games will be felt in London long after 2012.

  A super drug that could remove Alzheimer's(癡呆癥) ，heart disease and diabetes(糖屎病) and help people live to 100 is being developed by scientists. Their research is based on the iden?tification of three genes that improve long and healthy lives and prevent diseases of aging. Medi?cally controlling the proteins made by the " longevity genes" will allow millions to live longer, predicts Nir Barzilai.

Those people whose DNA strongly features the three genes are 80 percent less likely to de?velop Alzheimer's. The genes also fight against the deadly impact of smoking, bad diet,obesity and lack of exercise.

  Already，several laboratories are working on a pill to imitate the benefits of the genes and Dr Barzilai thinks it could be tested within three years. The pill could remove some diseases that damage the old people. "The advantage of finding a gene that involves longevity is that we can develop a drug that will imitate exactly what this gene is doing," he said. "The biology we're trying to uncover is that if we can imitate that,long life can be really terrific."

  Of the three longevity genes, two increase the production of so-called good cholesterol(膽固醇) ，which reduces the risk of heart disease. The third prevents diabetes. They were discov?ered by Dr Barzilai's team while studying the DNA of 500 Ashkenazi Jews with an average age of 100. The chances of living that long are one in 10,000 but the study group―which shared relatively few common ancestors―was 20 times more likely to hit the century. Dr Barzilai said, "Thirty percent of them were overweight and 30 percent smoked two packs of cigarettes a day for more than 40 years,however they could still live to 100."

  But Andrew Ketteringham, of the Alzheimer's Society, said. " Alzheimer's disease, a most common disease, is likely to be caused by a combination of genetic disposition(遺傳傾向) ，lifes?tyle and life events. Many genes are probably involved.”

(   ) 1. According to the text， some people are able to live to one hundred years because of

   A. magical medicine   B. three special genes

   C.  having no disease   D. once being sportsmen

(   ) 2. Why does the discovery of the longevity genes mean a lot?

   A.Because it can bring great benefits to economic development.

   B.Because it can help people change their unhealthy genes.

   C.Because it helps produce a drug that can make people live longer.

   D.Because it will help scientists to build up a new branch of biology. 

(   ) 3. From Paragraph 4 we can infer that        .

   A.longevity genes cannot help reduce diseases

   B.the study group is all from the same family

   C.good habits have no effects on the health of people

   D.the longevity genes may protect the people from the harm of bad habits 

(   ) 4. What is Andrew Ketteringham's attitude toward the study?

   A. Positive.   B. Critical.   C. Neutral.   D. Satisfied.
