41、年发现的。为了做实验，他试图在一个碟子中培育细菌，他注意到这个碟子看起来有些异常它里面有蓝色的霉。令他十分惊讶的是，他发现这种霉周围的细菌都死了，这意味着这种霉杀死了它们。弗莱明将这种霉用在另外一种细菌上做试验，发现它同样杀死了那种细菌。他立刻意识到这种霉或许能用于治疗由细菌引起的疾病。他将由这种霉制成的液体命名为“青霉素”。然而，青霉素的药物研发面临两个难题。首先，他难以找到一种方法来提纯药用的青霉素。其次，有效所需的青霉素也难以足量生产。在1940年，另外两位科学家霍华德弗洛里(澳大利亚人)和恩斯特钱恩(在德国出生的英国人)帮助解决了这些问题，成功地大量制造和测试这种新药物。由于这种新药为
42、第二次世界大战所需，政府审批青霉素的流程得以加快，并且于1944年大批量生产。正因为青霉素的广泛应用，战争期间的很多生命得以挽救。如果没有青霉素，很多人会死于疾病，甚至是很小的伤口。青霉素挽救了无数人的性命。成为20世纪最了不起的药物。由于他们的工作成果，这三名科学家，弗莱明、弗洛里和钱恩于1945年共同获得了诺贝尔医学奖。 A卷 学生用书P101(单独成册) 阅读理解AGrowing up in my household meant often hearing live music.When I was six years old, I took a traditional Irish st

71、标题归纳题。通读全文可知，本文介绍了汽油和柴油车将逐步被电动汽车代替以及电动交通工具在未来的发展。D项“驶向未来”形象地概括了文章的主旨，故选D项。9As used in Paragraph 2，the underlined word “hurdle” means “_”AaimBbarrierCconsequenceDstepB解析：词义猜测题。根据第二段中的“drivers concerns about running out of juice on a journey”可知，司机担心在路上没电的问题。因此，这是电动汽车普及的一个障碍，故选B项。10In the past，why did

73、动汽车的价格吓跑的；根据该段中的“Thanks to improvements in battery capacity，recharging times，performance and price，the current generation of electric cars is starting to persuade critics.”可知，随着电池容量、可充电次数的增加、汽车性能的改善和价格的优化，这一代电动汽车已经开始吸引消费者购买了。这说明以前的电动汽车在各方面还不够完善，人们认为不值那个价钱。故选A项。11What is the function of Paragraph 4?A

80、 often had holes in them so that people could string them together.【解题导语】本文是一篇说明文，主要按照时间顺序讲述了中国和世界上其他国家货币发展的历史。1F解析：根据空前的“people used many different kinds of things for buying and selling”及空后的“This exchange of goods and services for other goods and services is called bartering.”可知，此处主要讲的是“物物交换”，F项中的
81、“buying a chicken might cost several potatoes”是“物物交换”的一个例子，符合上下文文意，故选F项。2B解析：本文第一段讲的是“物物交换”；根据空后的“In 1，200 BC.people in China began to use shells(贝壳) as money.Usually the shells used as money were very small.”可知，第二段讲的是“贝壳作为货币使用”，故此空的作用是承上启下。B项中的“such exchanges”与第一段最后一句中的“This exchange”相呼应，且B项中的“Howe
82、ver”以及“impractical”表明“物物交换”有局限性，所以出现了更加方便携带的贝壳货币，符合上下文文意，故选B项。3D解析：根据第二段内容及空前的“many other countries around the world began to do the same”可知，许多其他国家也开始这样做了。“to do the same”指的就是“也开始用贝壳作为买卖的货币”，故D项“他们也使用小贝壳作为货币进行买卖”符合上下文文意，故选D项。4G解析：根据空前的“It wasnt long before the Chinese made round coins out of metal.”
83、可知，中国出现了金属制成的圆形钱币；根据空后的“By 500 BC.metal coins had begun to appear in countries like Persia and Greece，and later in the Roman Empire.”可知，到公元前500年这种金属钱币开始在其他国家出现。故空处应是解释这种金属钱币在其他国家出现的原因。故选G项“这种首次出现的钱币上通常有孔以便人们把它们串起来”。5C解析：根据空前的“the first paper banknotes were produced by the Chinese people”可知，此处讲到了纸币首先
