Watson’s life began in 1928. He made his most famous discovery in 1953. Together with Francis Crick, he found out the structure of DNA．This discovery was a huge step in understanding genes (基因). People had known about DNA since 1869, but for a long time, nobody knew its shape. To find out, Watson worked with Francis Crick in the UK. They studied X-ray pictures of DNA taken by another scientist, Rosalind Franklin. This led them to find out that DNA has two strands*. These strands twist (缠绕) around each other into a double helix*. Watson and Crick won the Nobel Prize in 1962. Watson’s work opened up new ways of understanding how genes are passed on from parents to children and how they affect our health and what they are like. _______ After the discovery, he continued his research and made more important discoveries in the field. He also wrote many books to share his knowledge with the public. His discovery changed the way we think about life and started modern studies of genes. Scientists today still build on his work to study new diseases and find better ways to help people. That is why he will always be remembered. His story shows us the power of being curious and hard-working in scientific discoveries. * A strand is a thin, long piece of something. In this passage, it means one of the two long thin parts that make up DNA． * Double helix: it is a shape of two long thin parts twisting around each other like a twisted ladder. 16．What might DNA look like according to the passage? A． B． C． D． 17．Which of the following can be put in “_______” in Paragraph 4? A．This stopped scientists from studying many diseases. B．Then they stopped their research. C．This helped scientists study many diseases. D．Nobody cared about his discovery. 18．What is the best title for the passage? A．The “Father of DNA” B．How to Win a Nobel Prize C．What is DNA D．Watson’s Different Views 【答案】16．D 17．C 18．A 【导语】本文是记叙文，介绍了被称为“DNA之父”的著名科学家詹姆斯·沃森的生平与科研成就，讲述了他与弗朗西斯·克里克发现DNA双螺旋结构的过程、获得诺贝尔奖的经历，以及他的研究对基因科学领域的深远影响，点明他因突出的科学贡献被世人铭记。 【详解】16．根据文章第三段“These strands twist around each other into a double helix.”以及文末注释“Double helix: it is a shape of two long thin parts twisting around each other like a twisted ladder”，可知DNA为双螺旋结构，与选项D的图片形态相符。 17．根据文章第四段“Watson’s work opened up new ways of understanding how genes are passed on from parents to children and how they affect our health and what they are like.”，可知沃森的研究为理解基因的遗传规律与基因对健康的影响开辟了新路径，由此可推知该研究能够帮助科学家研究疾病，符合上下文的逻辑衔接。 18．全文围绕“DNA之父”詹姆斯·沃森展开，介绍了他的核心科研成就、后续研究贡献以及他对基因科学的深远影响，“The ‘Father of DNA’”最能概括全文核心内容。 四、短文填空 （26-27九年级上·浙江杭州·阶段检测）阅读下面短文，在空白处填入1个适当的词，或填入括号中所给单词的正确形式。 Do you like travelling by train?
