Bamboo withered from the leaves, people aged from the feet; running every day, pharmacies need not be found. 竹从叶上枯，人从脚上老；天天跑步走，药铺不用找。 主题语境——人与社会。医学对人们的健康发挥着重要作用，我们要了解中外医学发展的现状和趋势，增强健康安全意识，积极弘扬传统中医药文化。 In 1967，the Chinese government formed a team of scientists with the objective of① discovering a new treatment for malaria②，and Tu Youyou was among the first researchers chosen.In the beginning，Tu Youyou went to Hainan，where malaria was more common，to study malaria patients.In 1969，she became the head of the project in Beijing，and decided to review ancient Chinese medical texts to find traditional botanical treatments for the disease.Her team examined over 2，000 old medical texts，and evaluated 280，000 plants for their medical properties.From their research，they discovered and tested 380 distinct ancient Chinese medical treatments that showed promise in the fight against malaria. One medical text from the fourth century suggested using the extract from sweet wormwood③ to treat a fever.Tu's team tested a collection of dried wormwood leaves but found no effect.They then tried boiling fresh wormwood，and using the liquid obtained from this to treat malaria，but this did not work either.Their project got stuck④.However，Tu Youyou would not acknowledge defeat⑤.She analysed the medical texts again，and by chance，she found one sentence suggesting a different way to treat the wormwood.She concluded that boiling the sweet wormwood apparently destroyed its medical properties.Using a lower temperature to draw out the extract，she found a substance that worked. ①with the objective of 为了 ②malaria n. 疟疾 ③sweet wormwood青蒿 ④get stuck被困住 ⑤acknowledge defeat 承认失败 Section Ⅰ　Welcome to the unit and Reading—Preview [对应学生用书P53] 1．genome n．基因组，染色体组 2．affect vt.影响；侵袭，使感染；深深打动 3．contract vt. 感染(疾病)；与……订立合同(或契约) n．合同，合约 4．virus n．病毒；(计算机程序中的)病毒 5．cancer n．癌症；邪恶，毒瘤 6．identify vt.找到，发现；确认，认出；显示，说明身份 7．delete vt.删去，删除 8．restore vt.恢复；修复；使复原，使复位 9．ultimately adv.最终；根本上 10．abnormal adj.反常的，畸形的 11．weapon n．武器，手段；兵器 12．fundamental adj.十分重大的，根本的；基础的，基本的 n．基本规律，根本法则，基础 13．restrict vt.限制，限定；束缚，妨碍；约束，管束 14．prohibit vt.(尤指以法令)禁止；使不可能 15．resistance n．抵抗力；抵制，反对；抵抗，反抗 16．characteristic n．特征，特点 adj.典型的，独特的 17．wrestle vi. & vt. 奋力对付，努力处理；摔跤 18．debate vt.& vi.讨论，辩论；仔细考虑，思考 n．讨论，争论；辩论 Step 1　Fast reading Check yourself to what degree you have remembered the text by filling in the blanks in the following passage.

Genome editing brings many exciting possibilities.1.As is well­known to you, genes play a critical role in shaping our lives, and our own personal genome contains information that helps determine our lifespan and affects our chances of contracting certain diseases. As a result, geneticists 2.have been trying(try) to identify which genes relate to which diseases, as they believe genome editing is 3.an effective means of disease treatment and prevention. In the near future, it will serve as a new weapon in the fight against diseases, 4.leading(lead) to a fundamental change in our approach to health care. However，5.with the technology continuing to develop at a fast pace, questions arise about how to use it 6.appropriately (appropriate).Genome editing also brings us some moral problems. Therefore, many people have all started 7.to wrestle(wrestle) with such issues. We have to find out how to keep the technology from running wild. This means 8.putting (put) appropriate controls in place to make sure that genome editing will work to our advantage. If we can't have them, genome editing would be as dangerous as a car out of control. In a word, there 9.is(be) still much to be explored and debated on genome editing. Without doubt, genome editing is one of the 10.greatest(great) inventions in the history of science. 学科网（北京）股份有限公司 $$
