In my view, you have to combine intelligence with willingness not to follow conventions when they block your path forward. Thus, these have come to be my rules for success. • 26 That might sound proud, but the fact is that you must always turn to people who are brighter than yourself. It’s like playing any game. Even as a child, I never wanted to play games with anyone who was as bad as I was. If you win, it gives you no pleasure. And in the game of science or life, the highest goal isn’t simply to win; it’s to win at something really difficult. 27 • Take risks. 28 If you are going to make a huge jump in science, you will very likely be unqualified to succeed by definition. Besides, you even have to be prepared to disbelieve your scientific heroes. This can be more than personally upsetting. • Never do anything that bores you. My experience in science is that someone is always telling you to do things, and then leave you alone. 29 In fact, I even find it hard to do well in something I like. It’s very hard to succeed if you don’t want to be with other scientists — you have to go to key meetings where you find key facts that would have escaped you. And you have to chat with your competitors, even if you find them unpleasant. So my final rule is: 30 A.To make a huge success, a scientist has to be prepared to get into deep trouble. B.Meet challenges with great courage. C.Put another way, it’s to go somewhere beyond your ability and come out on top. D.Be sure you always have someone to save you from a deep mess. E.I’m not good enough to do well in something I dislike. F.If you can’t stand to be with your real peers, get out of science. G.Avoid foolish people. 六、选词填空 in time    attend to    once and for all    subscribe to     as a result   thanks to     in general     draw a conclusion 31.Judging from what he said, I that he’d been lying. 32.My sister’s birthday is approaching.

It marks the smartphone giant’s entry into the 16 (compete) and challenging Chinese new energy vehicle (NEV) market. The SU7 series will be launched in nine different colors, at a price starting from215,900 yuan ($29,866) and mass 17 (produce) is expected to start in the first half of 2024. Customers and analysts had previously estimated that the SU7 18 (be) priced at 200,000 to 300,000 yuan. 19 (start) from Monday, the SU7 series has been on display in 59 stores across 29 cities in China, a staff member at the store told the Global Times, adding that people have been crowding 20 the showroom to see the car.

However, analysts believe 24 will drive innovation and progress in NEV technology, and help promote the expansion and market penetration (渗透) of NEVs by attracting more consumers, and increasing 25 (aware) and recognition of NEVs. 三、阅读理解 Researchers have developed a groundbreaking method of storing and handling valuable biological materials that removes the limitations of refrigerated storage. The novel method has potential applications in healthcare and scientific research. Biological materials that come from human cells, like enzymes, proteins, and antibodies, are crucial to developing new medicines and diagnostic tests. And they’re fragile. Extremely temperature-sensitive, they require a constant temperature during storage, handling, and transportation. If not stored or handled correctly, these materials will be inactive, which can be costly. Most biological materials are stored as liquids or freeze-dried powders and kept at low temperatures for the duration of their shelf life. This is achieved through a complex integrated system of refrigerators and freezers known as the cold chain. This requires a significant investment in equipment and infrastructure, making it expensive to maintain, and makes the cold chain prone to shipping delays, power outages, equipment failure and human error. Inspired from the home medicine cabinet (储藏柜), where medications are stored in the form of liquids, powder-filled capsules, and tablets, researchers at California Polytechnic State University have developed a new storage platform based on the humble tablet that would enable biological materials to be compressed (压缩) into a solid state. Tablets provide advantages to the storage and handling of biomaterials that the cold chain doesn’t. For one thing, they can be stored at room temperature. And, when they’re required, the tablet can be dissolved in water. “Our innovation makes storing and using biomaterials as straightforward as an effervescent tablet (泡腾片). Just drop it into water, mix, and it’s ready to go,” said the researcher of the study. The researchers say their new tablet-based storage and handling method is easy to use and doesn’t require special training, making it suitable for many applications. They also see potential uses beyond just improving the storage and handling of biological materials. By modifying (修改) the tablet coatings, this solid-state storage platform could withstand extreme conditions like heat, humidity, and chemicals. These changes might eventually allow injectable medications, such as insulin, to be taken orally. 26.What is a special requirement to store biological materials? A.Constant temperature maintenance. B.Exposure to various temperatures. C.Periodically freezing and melting. D.Direct contact with air. 27.What is the researchers’ attitude to their storage method? A.Favorable. B.Skeptical. C.Disappointed. D.Grateful. 28.Which word can replace the underlined word “withstand” in the last paragraph? A.Demonstrate. B.Stand. C.Adopt. D.Distinguish. 29.What is the text mainly about? A.Challenges of storing biological materials. B.The making process of effervescent tablets. C.Healthcare applications of biological materials. D.A new tablet storage method of biological materials. A new way to get rid of HIV from the body could one day be turned into a cure for infection by this virus, although it hasn’t yet been shown to work in people. The strategy uses a relatively recent genetic technique called CRISPR, which can make cuts in DNA to introduce errors into viral genetic material within immune cells (免疫细胞). “These findings represent a key advancement towards designing a cure strategy,” researcher Elena Herrera Carrillo at the University of Amsterdam in the Netherlands said in a statement. While infection with HIV was once nearly always fatal (致命的), those with the virus can now take drugs that stop it from reproducing. This gives them a nearly normal lifespan, as long as they diligently take their medicines every day. But when people are first infected, some of the virus inserts its DNA into their immune cells, where it stays dormant. If they stop taking their HIV medicines, this DNA “reawakens” and the virus starts spreading through their immune systems again. For a cure, we need some way of killing any dormant virus in the body. Several strategies have been tried, but none have so far been found to work. The latest approach uses a gene-editing system called CRISPR. Originally discovered in bacteria, this homes in on a specific DNA sequence, making cuts in it. By changing the DNA sequence being targeted, the system can potentially be turned into a form of gene therapy for many conditions, with the first such treatment having been approved last year in the US and UK as a cure for sickle cell anemia. Several groups are investigating using CRISPR which targets a gene in HIV as a way of disabling dorman t virus. Now, Carrillo and her team have shown that, when tested on immune cells in a dish, their CRISPR system could disable all viruses, removing them from these cells. The work is due to be presented at the European Congress of Clinical Microbiology and Infectious Diseases in Barcelona, Spain, next month. Jonathan Stoye at the Francis Crick Institute in London says that although the results are encouraging, the next step is trials in animals and eventually people to show the treatment can reach all the immune cells with dormant HIV. Some of these cells are thought to reside in bone marrow, but there may be other body sites involved too, he says. “There’s still a fair amount of uncertainty about whether there are other reservoirs in other parts of the body,” he says. A Californian firm called Excision BioTherapeutics has previously shown that a CRISPR-based approach can reduce the amount of dormant virus in monkeys infected with a similar virus to HIV. 30.How does the CRISPR underlying logic? A.Curing people who have HIV. B.Preventing virus breeding. C.Unneeded to absorb drugs regularly. D.Changing DNA’s sequence. 31.Which description is the most suitable for the underlined word “dormant” in paragraph 4? A.Having biological activity suspended. B.Represented on a cost of arms in a lying position with the head on the forefeet. C.Marked by a suspension of external activity. D.Associated with, carried out, or applied during a period of dormancy. 32.How does the group conduct their research in paragraph 7? A.By erasing the virus into the cell. B.By testing outside the body. C.By launching a clinical trial. D.By verifying CRISPR’s efficiency. 33.What can we infer from the last two paragraphs? A.The treatment enables it to reach the system. B.HIV is still living in human beings’ marrow. C.Several functions should be investigated. D.The strategy is still regarded as a prospect. 拓展延伸 1.假如你是李华,上周末参观了一场机器人展,你的朋友Bob对此很感兴趣,写信向你询问机器人展上的一些细节。请你给他写一封回信,和他介绍一下你最感兴趣的机器人。内容包括: 1. 该机器人的特点; 2. 你对该机器人的看法。 注意: 1. 词数80左右; 2. 可以适当增加细节,以使行文连贯。 Dear Bob, ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Yours, Li Hua 试卷第4页,共9页 试卷第5页,共9页 学科网(北京)股份有限公司 学科网(北京)股份有限公司 学科网(北京)股份有限公司 学科网(北京)股份有限公司 学科网(北京)股份有限公司 $$ Unit 1 Science and Scientists Reading and thinking分层作业 基础巩固 一、单句语法填空 1.The wound from the dog bite has become (infect). 2.The builders of the expressway (link) Jigzhi County in Qinghai Province to Barkam County in Sichuan Province know how complex it is to build a road in the region. 3.The advice we receive can be (contradict) sometimes and we have to make decisions for ourselves. 4.

The SU7 series will be launched in nine different colors, at a price starting from215,900 yuan ($29,866) and mass 17 (produce) is expected to start in the first half of 2024. Customers and analysts had previously estimated that the SU7 18 (be) priced at 200,000 to 300,000 yuan. 19 (start) from Monday, the SU7 series has been on display in 59 stores across 29 cities in China, a staff member at the store told the Global Times, adding that people have been crowding 20 the showroom to see the car. China’s NEV market has become the world’s biggest market 21 carmakers are ramping up (增加) efforts 22 (improve) technological capabilities amid (在……中) an ongoing price war. Meanwhile, Chinese NEV manufacturers are expanding overseas. About 19.5 percent of EVs purchased in Europe last year 23 (make) in China and this is on track to reach a quarter in 2024.3.29. It’s still unknown whether Xiaomi’s ambition to fulfil its auto business dream will succeed. However, analysts believe 24 will drive innovation and progress in NEV technology, and help promote the expansion and market penetration (渗透) of NEVs by attracting more consumers, and increasing 25 (aware) and recognition of NEVs. 【答案】 16.competitive 17.production 18.would be 19.Starting 20.into 21.where 22.to improve 23.were made 24.it 25.awareness 【导语】本文是一篇新闻报道,主要讲的是周四,中国科技巨头小米在北京举行了其首款电动汽车(EV)车型Speed Ultra 7 (SU7)的发布会。 16.考查形容词。句意:这标志着这家智能手机巨头进入了竞争激烈、充满挑战的中国新能源汽车市场。空格处用形容词作定语,修饰名词短语Chinese new energy vehicle (NEV) market,compete的形容词是competitive,意为“有竞争力的”,故填competitive。 17.考查名词。句意:SU7系列将推出9种不同的颜色,价格从215,900元(29,866美元)起,预计将于2024年上半年开始量产。mass是形容词,修饰名词,此处表示“量产”,空格处意为“生产”,名词是production,是不可数名词,故填production。 18.考查时态。句意:客户和分析师此前预计,SU7的售价将在人民币20万至30万元之间。根据语境可知,句子表示“SU7的售价将在人民币20万至30万元之间”,句子用将来时,由estimated可知,句子用过去将来时,因此空格处是would be。故填would be。 19.考查非谓语动词。句意:该店的一名工作人员告诉《环球时报》,从周一开始,SU7系列已经在中国29个城市的59家门店展出,并补充说人们已经挤进展厅看这款车。句中谓语是has been,空格处用非谓语动词,the SU7 series和start之间是主谓关系,因此空格处用现在分词作状语,位于句首,首字母大写,故填Starting。 20.考查介词。句意:该店的一名工作人员告诉《环球时报》,从周一开始,SU7系列已经在中国29个城市的59家门店展出,并补充说人们已经挤进展厅看这款车。crowd into是固定短语,意为“挤进”,因此空格处用介词into,故填into。 21.考查定语从句。句意:中国新能源汽车市场已成为全球最大的市场,在持续的价格战中,汽车制造商正加大力度提高技术能力。空格处引导的是限制性定语从句,从句中缺少状语,先行词market是地方,因此空格处用关系副词where引导定语从句,故填where。 22.考查不定式。句意:中国新能源汽车市场已成为全球最大的市场,在持续的价格战中,汽车制造商正加大力度提高技术能力。根据语境可知,句子表示“中国新能源汽车市场已成为全球最大的市场,在持续的价格战中,汽车制造商正加大力度提高技术能力”,因此空格处用不定式表目的,故填to improve。 23.考查时态,语态和主谓一致。句意:去年在欧洲购买的电动汽车中,约有19.5%是在中国制造的,这一比例有望在2024年达到四分之一。EVs与make之间是被动关系,且由last year可知,句子描述过去的事情,因此句子用一般过去时的被动语态,主语19.5 percent of EVs是复数,因此空格处是were made。故填were made。 24.考查代词。句意:然而,分析人士认为,这将推动新能源汽车技术的创新和进步,并通过吸引更多消费者,提高对新能源汽车的认识和认可,帮助促进新能源汽车的扩张和市场渗透。空格处用it指代前面的“Xiaomi’s ambition to fulfil its auto business dream”,故填it。 25.考查名词。句意:然而,分析人士认为,这将推动新能源汽车技术的创新和进步,并通过吸引更多消费者,提高对新能源汽车的认识和认可,帮助促进新能源汽车的扩张和市场渗透。increasing是形容词,修饰名词,aware的名词是awareness,是不可数名词,意为“意识,认识”,故填awareness。 三、阅读理解 Researchers have developed a groundbreaking method of storing and handling valuable biological materials that removes the limitations of refrigerated storage. The novel method has potential applications in healthcare and scientific research. Biological materials that come from human cells, like enzymes, proteins, and antibodies, are crucial to developing new medicines and diagnostic tests. And they’re fragile. Extremely temperature-sensitive, they require a constant temperature during storage, handling, and transportation. If not stored or handled correctly, these materials will be inactive, which can be costly. Most biological materials are stored as liquids or freeze-dried powders and kept at low temperatures for the duration of their shelf life. This is achieved through a complex integrated system of refrigerators and freezers known as the cold chain. This requires a significant investment in equipment and infrastructure, making it expensive to maintain, and makes the cold chain prone to shipping delays, power outages, equipment failure and human error. Inspired from the home medicine cabinet (储藏柜), where medications are stored in the form of liquids, powder-filled capsules, and tablets, researchers at California Polytechnic State University have developed a new storage platform based on the humble tablet that would enable biological materials to be compressed (压缩) into a solid state. Tablets provide advantages to the storage and handling of biomaterials that the cold chain doesn’t. For one thing, they can be stored at room temperature. And, when they’re required, the tablet can be dissolved in water. “Our innovation makes storing and using biomaterials as straightforward as an effervescent tablet (泡腾片). Just drop it into water, mix, and it’s ready to go,” said the researcher of the study. The researchers say their new tablet-based storage and handling method is easy to use and doesn’t require special training, making it suitable for many applications. They also see potential uses beyond just improving the storage and handling of biological materials. By modifying (修改) the tablet coatings, this solid-state storage platform could withstand extreme conditions like heat, humidity, and chemicals. These changes might eventually allow injectable medications, such as insulin, to be taken orally. 26.What is a special requirement to store biological materials? A.Constant temperature maintenance. B.Exposure to various temperatures. C.Periodically freezing and melting. D.Direct contact with air. 27.What is the researchers’ attitude to their storage method? A.Favorable. B.Skeptical. C.Disappointed. D.Grateful. 28.Which word can replace the underlined word “withstand” in the last paragraph? A.Demonstrate. B.Stand. C.Adopt. D.Distinguish. 29.What is the text mainly about? A.Challenges of storing biological materials. B.The making process of effervescent tablets. C.Healthcare applications of biological materials. D.A new tablet storage method of biological materials. 【答案】26.A 27.A 28.B 29.D 【导语】本文是一篇说明文。主要介绍了加州州立理工大学的研究人员通过研究,找到了可以在常温下存储和处理生物材料的方法。 26.细节理解题。根据第二段“And they’re fragile. Extremely temperature-sensitive, they require a constant temperature during storage, handling, and transportation. If not stored or handled correctly, these materials will be inactive, which can be costly.(而且它们很脆弱。它们对温度极为敏感,在储存、搬运和运输过程中需要恒温。如果储存或处理不当,这些材料将处于非活性状态,这可能会带来高昂的成本)”可知,生物材料对温度极其敏感,在储存、处理和运输过程中需要恒定的环境温度。故选A。 27.推理判断题。根据第五段““Our innovation makes storing and using biomaterials as straightforward as an effervescent tablet (泡腾片). Just drop it into water, mix, and it’s ready to go,” said the researcher of the study.(该研究的研究人员说:“我们的创新使生物材料的储存和使用变得像泡腾片一样简单。只需将其放入水中,混合,即可使用。”)”以及最后一段“The researchers say their new tablet-based storage and handling method is easy to use and doesn’t require special training, making it suitable for many applications. They also see potential uses beyond just improving the storage and handling of biological materials.(研究人员表示,他们新的基于平板电脑的存储和处理方法易于使用,不需要特殊培训,因此适用于许多应用。他们还看到了除了改善生物材料的储存和处理之外的潜在用途)”可知,研究人员认为储存方法很简单,并易于使用,由此可知,研究人员对他们的储存方法持赞成的态度。故选A。 28.词句猜测题。根据最后一段“By modifying (修改) the tablet coatings, this solid-state storage platform could withstand extreme conditions like heat, humidity, and chemicals.(通过修改平板电脑的涂层,这种固态存储平台可以withstand高温、潮湿和化学物质等极端条件)”可推知,此处表示经过涂层修改后,固态存储平台可以承受极端条件,划线单词表示“承受”,与Stand意义相近。故选B。 29.主旨大意题。通读全文以及第一段“Researchers have developed a groundbreaking method of storing and handling valuable biological materials that removes the limitations of refrigerated storage. The novel method has potential applications in healthcare and scientific research.(研究人员开发了一种突破性的储存和处理有价值生物材料的方法,消除了冷藏的局限性。这种新方法在医疗保健和科学研究方面具有潜在的应用前景)”可知,本文主要介绍了加州州立理工大学的研究人员通过研究,找到的一种可以在常温下存储和处理生物材料的方法。故选D。 A new way to get rid of HIV from the body could one day be turned into a cure for infection by this virus, although it hasn’t yet been shown to work in people. The strategy uses a relatively recent genetic technique called CRISPR, which can make cuts in DNA to introduce errors into viral genetic material within immune cells (免疫细胞). “These findings represent a key advancement towards designing a cure strategy,” researcher Elena Herrera Carrillo at the University of Amsterdam in the Netherlands said in a statement. While infection with HIV was once nearly always fatal (致命的), those with the virus can now take drugs that stop it from reproducing. This gives them a nearly normal lifespan, as long as they diligently take their medicines every day. But when people are first infected, some of the virus inserts its DNA into their immune cells, where it stays dormant. If they stop taking their HIV medicines, this DNA “reawakens” and the virus starts spreading through their immune systems again. For a cure, we need some way of killing any dormant virus in the body. Several strategies have been tried, but none have so far been found to work. The latest approach uses a gene-editing system called CRISPR. Originally discovered in bacteria, this homes in on a specific DNA sequence, making cuts in it. By changing the DNA sequence being targeted, the system can potentially be turned into a form of gene therapy for many conditions, with the first such treatment having been approved last year in the US and UK as a cure for sickle cell anemia. Several groups are investigating using CRISPR which targets a gene in HIV as a way of disabling dorman t virus. Now, Carrillo and her team have shown that, when tested on immune cells in a dish, their CRISPR system could disable all viruses, removing them from these cells. The work is due to be presented at the European Congress of Clinical Microbiology and Infectious Diseases in Barcelona, Spain, next month. Jonathan Stoye at the Francis Crick Institute in London says that although the results are encouraging, the next step is trials in animals and eventually people to show the treatment can reach all the immune cells with dormant HIV. Some of these cells are thought to reside in bone marrow, but there may be other body sites involved too, he says. “There’s still a fair amount of uncertainty about whether there are other reservoirs in other parts of the body,” he says. A Californian firm called Excision BioTherapeutics has previously shown that a CRISPR-based approach can reduce the amount of dormant virus in monkeys infected with a similar virus to HIV. 30.How does the CRISPR underlying logic? A.Curing people who have HIV. B.Preventing virus breeding. C.Unneeded to absorb drugs regularly. D.Changing DNA’s sequence. 31.Which description is the most suitable for the underlined word “dormant” in paragraph 4? A.Having biological activity suspended. B.Represented on a cost of arms in a lying position with the head on the forefeet. C.Marked by a suspension of external activity. D.Associated with, carried out, or applied during a period of dormancy. 32.How does the group conduct their research in paragraph 7? A.By erasing the virus into the cell. B.By testing outside the body. C.By launching a clinical trial. D.By verifying CRISPR’s efficiency. 33.What can we infer from the last two paragraphs? A.The treatment enables it to reach the system. B.HIV is still living in human beings’ marrow. C.Several functions should be investigated. D.The strategy is still regarded as a prospect. 【答案】30.D 31.A 32.B 33.D 【导语】这是一篇说明文。文章介绍了一种利用CRISPR基因编辑技术来消除体内HIV的新方法,尽管尚未在人类身上证明其有效性,但这种策略有望成为治愈HIV感染的方法。 30.细节理解题。由第六段“The latest approach uses a gene-editing system called CRISPR. Originally discovered in bacteria, this homes in on a specific DNA sequence, making cuts in it. By changing the DNA sequence being targeted, the system can potentially be turned into a form of gene therapy for many conditions, with the first such treatment having been approved last year in the US and UK as a cure for sickle cell anemia. (最新的方法使用了一种名为CRISPR的基因编辑系统。该系统最初在细菌中发现,它针对特定的DNA序列进行切割。通过改变靶向的DNA序列,该系统有可能成为许多疾病的基因治疗形式,去年美国和英国批准了第一种治疗镰状细胞贫血的方法)”可知,CRISPR的基本原理是通过改变DNA序列来进行基因编辑,从而有可能成为多种疾病的基因治疗方法。故选D项。 31.词句猜测题。由第四段“But when people are first infected, some of the virus inserts its DNA into their immune cells, where it stays dormant. If they stop taking their HIV medicines, this DNA “reawakens” and the virus starts spreading through their immune systems again. (但是当人们第一次被感染时,一些病毒会将其DNA插入他们的免疫细胞中,并在那里保持dormant。如果他们停止服用艾滋病毒药物,这种DNA会“重新唤醒”,病毒会再次开始通过他们的免疫系统传播)”可知,停止服用艾滋病毒药物,进入人体免疫细胞的DNA会“重新唤醒”,说明之前这些DNA休眠了,dormant在此处的意思是“暂停生物活动”。故选A项。 32.细节理解题。由第七段中“Now, Carrillo and her team have shown that, when tested on immune cells in a dish, their CRISPR system could disable all viruses, removing them from these cells. (现在,Carrillo和她的团队已经证明,当在培养皿中的免疫细胞上进行测试时,他们的CRISPR系统可以禁用所有病毒,将它们从这些细胞中清除)”可知,他们的研究是在体外进行的。故选B项。 33.推理判断题。由倒数第二段中“Jonathan Stoye at the Francis Crick Institute in London says that although the results are encouraging, the next step is trials in animals and eventually people to show the treatment can reach all the immune cells with dormant HIV. (伦敦弗朗西斯·克里克研究所的乔纳森·斯托耶说,尽管结果令人鼓舞,但下一步是在动物身上进行试验,并最终在人体内进行试验,以证明这种治疗可以到达所有休眠的艾滋病毒免疫细胞)”和最后一段“A Californian firm called Excision BioTherapeutics has previously shown that a CRISPR- based approach can reduce the amount of dormant virus in monkeys infected with a similar virus to HIV. (一家名为Excision BioTherapeutics的加利福尼亚公司此前已经证明,基于CRISPR的方法可以减少感染与HIV类似病毒的猴子体内休眠病毒的数量)”可知,这种策略有其好处,仍被视为一种前景。故选D项。 拓展延伸 1.假如你是李华,上周末参观了一场机器人展,你的朋友Bob对此很感兴趣,写信向你询问机器人展上的一些细节。请你给他写一封回信,和他介绍一下你最感兴趣的机器人。内容包括: 1. 该机器人的特点; 2. 你对该机器人的看法。 注意: 1. 词数80左右; 2. 可以适当增加细节,以使行文连贯。 Dear Bob, ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Yours, Li Hua 【答案】One possible version: Dear Bob, Knowing from your letter that you are interested in robots, I am writing to share my wonderful experience with you.
