He was saying that，“If you want people to grow up，you have to stop treating them like children.”In America，families are close but children are encouraged to be independent，to make their own decisions，even at a very early age. Its not unusual for a child of seven to be given an allowance(津贴)every week. The child is encouraged to save some of the money but he or she can spend it on whatever they choose，for example，buying clothes，school supplies or CDs.Some teenagers even have their own credit cards! Thats a big responsibility since even adults are tempted to overspend when they have credit cards.From an early age，American children are asked for their opinions and they are included in family decisionmaking.At the dinner table，teenagers will be listened to on any topic，from politics to buying a new family car or where the family will go on vacation.In this way，teenagers are getting practice in becoming individuals：they are learning how to stand on their own two feet.Many Chinese young people are becoming almost as interested as American teens in searching for independence.They want to express those qualities that make them unique human beings. You can see this in the way they dress, the music they listen to and the friends they choose.“Super Girl” Li Yuchun caught the imagination of Chinese teenagers on the “Super Girl” television contest.She was not the traditional “nice，young Chinese girl”With her short，spiky hair and boylike clothes，she was telling everyone that she was different. She had the courage to be her own person and to stand on her own two feet.and she won!There is an old saying，“Everyone should carefully observe which way his heart draws him and then choose that way with all his strength.”If you do this，step by step，over a period of time，you may find that you have become the person you always wanted to be.【解题导语】生活中几乎没有东西比责任更重要，更能够帮助别人，并让别人觉得你信任他。作者通过介绍美国人教育孩子的方式来论证这个道理并指出中国的年轻人也开始追求独立。1The passage is intended to encourage the youth to_.Asave money for useful things Bbecome independentCexpress their great ambitions Dmake important decisions2A child of seven is given an allowance so that he can_.Abe accepted as a popular guy Blearn to decide how to use moneyCoverspend money without care Dhave school supplies of his own3The author implies that many Chinese children_.Aare more independent than Americans Bshould become interested in AmericaCare happy with their present situation Dare not satisfied to be nice，quiet ones4The main idea of the last paragraph is_.Athat we should do things step by step Bwhy we should understand our desiresCwhat we should plan for our own life Dhow we can manage to realize our dreamsBFour people in the England，back in 1953，stared at Photo 51.It wasnt mucha picture showing a black X. But three of these people won the Nobel Prize for figuring out what the photo really showedthe shape of DNA.The discovery brought fame and fortune to scientists James Watson，Francis Crick，and Maurice Wilkins. The fourth，the one who actually made the picture，was left out.Her name was Rosalind Franklin.“She should have been up there，”says historian Mary Bowden.“If her photos hadnt been there，the others couldnt have come up with the structure.”One reason Franklin was missing was that she had died of cancer four years before the Nobel decision.But now scholars doubt that Franklin was not only robbed of her life by disease but robbed of credit by her competitors.At Cambridge University in the 1950s，Watson and Crick tried to make models by cutting up shapes of DNAs parts and then putting them together. In the meantime，at Kings College in London，Franklin and Wilkins shone Xrays at the molecule(分子)The rays produced patterns reflecting the shape.But Wilkins and Franklins relationship was a lot rockier than the celebrated teamwork of Watson and Crick. Wilkins thought Franklin was hired to be his assistant.But the college actually employed her to take over the DNA project.What she did was produce Xray pictures that told Watson and Crick that one of their early models was inside out.And she was not shy about saying so.That angered Watson，who attacked her in return，“Mere inspection suggested that she would not easily bend.Clearly she had to go or be put in her place.”As Franklins competitors, Wilkins, Watson and Crick had much to gain by cutting her out of the little group of researchers, says historian Pnina AbirAm.In 1962 at the Nobel Prize awarding ceremony，Wilkins thanked 13 colleagues by name before he mentioned Franklin.Watson wrote his book laughing at her. Crick wrote in 1974 that“Franklin was only two steps away from the solution.”No，Franklin was the solution.“She contributed more than any other player to solving the structure of DNA. She must be considered a codiscoverer，”AbirAm says. This was backed up by Aaron Klug, who worked with Franklin and later won a Nobel Prize himself.Once described as the“Dark Lady of DNA”，Franklin is finally coming into the light.【解题导语】文章通过几个科学家对女科学家Rosalind Franklin在DNA研究中作用的讨论，客观地论述了她的贡献。这位曾经被誉为“DNA隐身女士”的Franklin对DNA研究的贡献在作者的叙述中终于浮出水面。5What is the text mainly about?AThe disagreements among DNA researchers.
