On June 26, 2000, two scientists, called Francis Collins and Craig Venter, told the world that they could read the whole “map” of the human body: DNA. DNA is something that everybody has, and it tells the body what to do. DNA is the reason that we look like our mother and father, because we get some of their DNA to make our own.

People have been trying to understand the human body for a long time. In 1860, Gregor Mendel discovered a special reason why we look the same as other people in our family. It is because of small things named “genes” in our body. In 1953, James Watson and Francis Crick made another discovery and found out that those small parts are real messages written in the DNA with a special language.

In 1961, Marshall Nirenberg and Johann Matthaci found a message in DNA showing how DNA tells the cell(細胞)to build its parts. Scientists have now found all the words in the DNA map, but we still do not understand what they all do. By understanding what just one “word”   means, we can help save more people from several illnesses.

Most people hope that this will help make better medicine and help sick people. Other people worry that when people begin to know more words and find out lots of other information, we might use it in a wrong way, just to make people more attractive, or stop sick people from getting jobs. Man would have to meet a lot of trouble if DNA technic wasn’t limited(限制)in use.

A. In 1860.      B. In 1953.       C. In 1961.      D. In 2000.

(  ) 52. What does the underlined word “ genes” mean?

C. Small parts of DNA.                D. DNA.  ,,

(  )53. What did the two scientists first discover in 1961 ?

A. The “map” of DNA.                B. A new illness.        

C. The language of DNA.              D. A message of DNA.

(  ) 54. What can we do if we understand some “ words” of the language inside the body

A. Make people get new jobs.           B. Make medicine for illnesses.

C. Make maps of human.               D. Make people less attractive.

(  ) 55. What do people think about this work’?

A. It can cause good or bad results.               B. It can cause only good results.

C. It can cause good results but won’t work.        D. It can cause only bad results.

Lang Lang is a world-class young pianist who grew up in Shenyang. He went to a piano school in Beijing when he was just eight, "You need fortune(運氣)," his father said. "But      you work hard, no fortune will come."

    What made him       was that his piano teacher in Beijing didn't like him. "You have no talent(天賦).You will never be a pianist." As an eight-year-old boy, Lang Lang was badly       . He decided that he didn't want to be a pianist any more. For the next two weeks, he didn't touch the piano. Wisely(明智的)his father didn't      ,but wait.

    Luckily the day came when his teacher asked him to play some holiday songs. He didn't want to, but as he placed his fingers on the piano keys, he        he could show other people that he had ability to do it well. That day he told his father that he wanted to      with a new teacher. From that point on, everything turned around.

    He started         competitions. In the 1994 International Young Pianists Competition when it was announced that Lang Lang had won, he was too        to hold back his tears. Soon it was clear that he couldn't stay in China forever-he had to play on the world's big stages. In 1997 Lang Lang       again, this time to Philadelphia, US. There he spent two years practicing and by 1999 he had worked hard enough for fortune to take over.After his      performance at Chicago's Raviniu Festival, gigs(演奏會)in Lincoln Center and Camegie Hall started pouring in. Lang Lang finally worked to reach the place where fortune spots(找到)him, and lets him shine.
