4.EFour people in England, back in 1953, stared at photo 51. it wasn’t much –a picture showing a black X. But three of these people won the Nobel Prize for figuring out what the photo really showed—the 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 photo hadn’t been there, the others couldn’t 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 scholar doubt that Franklin was not only robbed of her life by disease but robbed of credit by her competitions.At Cambridge University in the 1950s, Watson and Crick tried to make models by cutting up shapes of DNA’s parts and then putting them together. In the meantime, at king’s college in London, Franklin and Wilkins shone X-rays at the molecule(分子). The rays produced patterns reflecting the shape.But Wilkins and Franklin’s 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 X-ray 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 Franklin’s competitors, Wilkins, Watson and Crick had much to gain by cutting her out of the little group of researchers, says historian Pnina Abir-Am. 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 “Franklins 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 co-discoverer,” Abir-Am 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.57. What is the text mainly about?A. The disagreements among DNA researchers.B. The unfair treatment of Franklin.C. The process of discovering DNA.DThe race between two teams of scientists.

    What may be the author’s attitude toward the“Labor Market Equilibrium”?( )

    A.Positive
    B.Neutral
    C.Ambiguous
    D.Suspicious

    答案:B
    解析:
    态度题。根据题干定位到文中的第二部分,通过文中的词汇can be identified,has increased可以发现作者是很客观地在讲述劳动力市场均衡,因此B项“中立的”正确。其他三项,A项“积极的”、C项“模棱两可的”和D项“怀疑的”均不符合文章描述。故本题选B。参考译文:劳动力市场在经济学中,劳动是用来衡量人类所做工作的尺度。它通常与土地和资本等其他生产要素形成对比。它总是被当作一种商品——在市场上买卖的东西。公司为一个小时的劳动支付的工资单价被视为该劳动力的价格。当然,劳动力不同于其他商品。首先,其他商品的卖家只要卖到好价,不在乎谁买他们的产品。而劳动者非常关心谁购买他们的劳动力,因为该公司会成为他们的雇主。因此,劳动者关注工作条件、同事关系、通勤距离、晋升的可能性、声望、成就感等。劳动力的第二个显著特征是价格在市场中的特定含义:工资单价。人们一生中的主要收入来自他们的工作——来自出卖他们的劳动力——因此他们的工资水平将决定他们能在多大程度上养活自己和家人。因此,工资差异引发了经济中有关公平和公正的重要问题。劳动力市场既包括本地市场,又包括国家甚至国际市场,是由不同资质、技能和地理位置的较小的相互作用的劳动力市场组成的。它们依赖于雇主和求职者之间关于工资单价、就业条件、竞争水平和工作地点等信息的交流。劳动力市场均衡由于技术变革和资本积累,劳动力需求增加。许多人对这个事实感到惊讶。他们看到的是新技术正在毁灭工作岗位,而非创造就业机会。随着计算机和信息时代的到来,裁员成了20世纪90年代的流行语,并淘汰了数百万“好”工作,甚至是经理级别的岗位。那么,技术变革怎么可能创造就业机会并增加劳动力需求呢?技术变革在摧毁一些工作的同时也创造了其他工作机会。但它创造的工作机会要多于它所破坏的岗位。平均来说,新工作的工资比旧工作高。但是为了从技术进步中受益,人们必须掌握新的技能并更换工作。例如,在过去的15年里,对打字员的需求几乎降到了零,但是对能打字(用电脑而不是打字机)的人员和其他岗位的人员需求增加了。这些人比打字员创造的价值更高。因此,对具备打字技能的人的需求增加了。由于人口增长、技术变革和国内资本积累,劳动力供应增加了。家庭生产的机械化,如快餐准备服务(冰箱和微波炉)和洗衣服务(自动洗衣机、甩干机和晾衣架),减少了全职太太做家务花费的时间,因此劳动力供给大幅增加。结果,劳动力供给稳步增长,但增速低于劳动力需求。技术进步和资本积累使劳动力需求增加,超过了人口增长,而且国内生产的技术变革增加了劳动力供应,因此,工资提升了,就业岗位增加。但并不是每个人都能享受高薪带来的繁荣。一些群体被抛在后面,一些人甚至目睹他们的工资单价下降。这是为什么?可以确定主要有以下原因。首先,技术变革以不同的方式影响不同群体的边际生产率。高技能计算机工人从信息革命中受益,而低技能工人则遭受损失。对高技能工人的需求增加了,对低技能工人的需求减少了。其次,国际竞争降低了对低技能工人的边际收入产品的需求,从而降低了对其劳动力的需求。

  • 第5题:

    说明Watson-Crick建立的DNA双螺旋结构的特点。


    正确答案:(1)DNA分子有两条反向平行的多核苷酸链相互盘绕形成双螺旋结构。两条链围绕同一个“中心轴”形成右手螺旋,双螺旋的直径为2nm。
    (2)由脱氧核糖和磷酸间隔相连而形成的亲水骨架在双螺旋的外侧,而疏水的碱基对则在双螺旋的内部,碱基平面与中心轴垂直,螺旋旋转一周约为10个碱基对(bp),螺距为3.4nm,这样相邻碱基平面间隔为0.34nm,并有一个36º的夹角,糖环平面则于中心轴平行。
    (3)两条DNA链借助彼此碱基之间形成的氢键而结合在一起。根据碱基结构的特征,只能形成嘌呤与嘧啶配对。既A与T配对,G与C配对,A-T间有2个氢键,G-C间有3个氢键。
    (4)在DNA双螺旋结构中,两条链配对偏向一侧,形成一条大沟和一条小沟。这两条沟特别是大沟对蛋白质识别DNA双螺旋结构上的特定信息非常重要,只有沟内蛋白质才能识别到不同碱基顺序。
