21、t cost-effective way to use the rice will be to make it into a cream to be put on the skin.”可知,研究人员认为最简单且最节约成本的方式就是把这种大米加工成膏,涂在皮肤上。故选B。A项“通过把它转化成蛋白质”;C项“通过把它附着在HIV病毒上”;D项“通过把它添加到口服药物中”。3.D细节理解题。根据最后一段最后一句“The scientific team says further testing is needed to ensure that the genetic engineering proce

22、ss does not produce any additional chemicals that could be dangerous to human bodies.”可知,科学家们认为还需要做进一步测试,以确保基因工程过程的安全性。故选D。A项“它不会产生危险的化学物质”,B项“它产生了危险的化学物质”,由文章最后一段中的最后一句可知,是否产生有害的化学物质是有待确定的事;C项“它是为发达国家设计的”,由文章的第三段和第四段的首句可排除。4.D推理判断题。根据主旨段第一段提到的“According to a recent study, a new kind of genetically

Now, a group of researchers has figured out the

24、 molecular(分子的) structure of a key protein that the coronavirus uses to invade human cells.1 Previous research shows that the coronaviruses invade cells through the so-called “spike” proteins, but those proteins take on different shapes in different coronaviruses.Figuring out the shape of the spike

25、protein in the novel coronavirus is the key to figuring out how to target the virus.2 But the spike protein is the major surface protein that it uses to combine with a receptoranother protein that acts like a doorway into a human cell.After the spike protein combines with the human cell receptor, th

26、e viral membrane combines with the human cell membrane, allowing the genome of the virus to enter human cells and begin infection. To prevent attachment and combination, people will prevent entry.3 Earlier this month, researchers published the genome of the novel coronavirus. They identified the spe

27、cific genes that code for the spike protein and then sent that gene information to a company that creates the genes.The group then injected those genes into mammalian cells in a lab dish.4 Next, using a very detailed microscopy technique called cryogenic electron microscopy, the group created a 3D “

28、map”, or “blueprint” of the spike proteins.The blueprint revealed the structure of the molecule.5 Its a very important step forward and may help with the development of a vaccine against COVID-19.The spike protein would be the likely choice for the rapid development of vaccine antigens and treatment

29、s.A.Soon those cells produced the spike proteins.B.It mapped the location of each of its atoms in space.C.It potentially opens the door to the development of a vaccine.D.Compared to normal vaccine development, it may take 10 years.E.But to target this protein, humans need to know what it looks like.

30、F.The structure shows that the molecule is stable in the correct situation.G.The coronavirus uses many different proteins to reproduce and invade cells.1. 2. 3. 4. 5.【答案】本文是一篇新闻报道。全球各地的研究人员都在研发疫苗和药物来对抗新型冠状病毒。现在,一组研究人员已经弄清这种冠状病毒用以入侵人类细胞的一种关键蛋白质的分子结构,为疫苗的进一步研发打开了大门。1.C根据设空处前一句可知,一组研究人员已经弄清这种冠状病毒用以入侵人类

31、细胞的一种关键蛋白质的分子结构,说明这项研究可能为疫苗的研发打开了大门。故选C项。误解分析:有的同学会误选F项,认为它和前面一句话中都提到了蛋白质的分子结构,但是该项无法引起下文和本文的主题。2.GG项中的 many different proteins与下一句中的 major surface protein对应,即虽然冠状病毒利用许多不同的蛋白质复制并入侵细胞,但刺突蛋白是其用来与受体另一种充当进入人体细胞的通道的蛋白质结合的主要表面蛋白。3.E上一句说到阻止附着和结合,人们就能阻止病毒进入(人体细胞),解决问题要“知己知彼”,E项“但是要锁定这种蛋白质,人们需要知道它是什么样子的”承接上文

32、,并且衔接下文的“研究者发布新型冠状病毒的基因组并揭示刺突蛋白的分子结构”,符合语境。4.A根据上一句可知,研究小组将这些基因注入实验室培养器皿中的哺乳动物细胞中。A项中的“those cells produced”符合生物的特性,与上一句衔接紧密,且与下一句“接下来,使用一种叫作低温电子显微术的非常精细的显微技术,这个小组创造了一份这些刺突蛋白的3D地图,或者说蓝图”紧密结合。5.B根据上文的a 3D “map”,or “blueprint”可知这是研究人员的重大发现,设空处前一句提到这份蓝图揭示了这种分子的结构,B项“它绘制了它的每个原子的空间分布形态图”承接上文。“It”指代的是上一句中

33、的“The blueprint”。III.语法填空One of the most famous Chinese medical 1(treat) is Chinese acupuncture, dating from the Stone Age. As acupuncture developed, nine different kinds of needles appeared, which2(have) different shapes. The majority of acupuncturists now use stainless steel needles. They push nee

34、dles into the skin at certain points on the body3(call) acupuncture points. So far, more than 360 acupuncture points4(identify), each linked to a different part of the body. Over the years, not only has acupuncture been used to treat physical and 5(mentally) problems, but it has also been applied to

35、 treat people 6 abuse alcohol, tobacco or drugs. 7it is not clear how acupuncture actually works, it is8fact that acupuncture has become very popular. Today,it has come into widespread use around the world9a symbol of traditional Chinese culture.While doubts about its safety have10(gradual) disappea

36、red, interest continues to grow.1. 2. 3. 4. 5.6. 7. 8. 9. 10.【答案】1.treatments考查名词及其单复数。根据one of.结构可知,设空处应用可数名词复数,表示“最著名的中医疗法之一”,故填treatments。2.had考查时态。根据上下文语境以及主句的时态可知,此处叙述过去发生的事情,所以which引导的定语从句中谓语动词用一般过去时。3.called考查过去分词。设空处作定语,修饰其前的名词points,动词call与其逻辑主语之间是被动关系。故用过去分词形式。4.have been identified考查动词的时态

37、和语态以及主谓一致。根据时间状语So far可知,设空处动作已经发生并且对现在造成了影响,且与主语之间是被动关系。故用现在完成时的被动语态。主语为复数意义,故用have been identified。5.mental考查形容词。空前and连接两个并列的成分,physical为形容词,故此处应填形容词mental。6.who/that考查定语从句。设空处引导定语从句,修饰先行词people,关系词在从句中作主语,故填who/that。7.While/Though/Although考查连词。分析句子可知,此处为状语从句,与主句意思上形成让步关系,故填While/Though/Although。8

38、.a考查冠词。fact在文中是首次出现,故此处用不定冠词泛指“一件事实”。9.as考查介词。as意为“作为”,符合语境。故用介词as。10.gradually考查副词。空处修饰谓语have disappeared。故用副词形式。IV.读后续写阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。续写词数应为 150词左右。In 1974,after filling out fifty applications, going through four interviews, and winning one offer,I took what I could geta teaching jo

45、t thinking that Iwould be fired. To my great surprise, my boss didnt glare at me with burning eyes. Instead,hepatiently named my problems that as a teacher I shouldnt have ignored the bad behavior of mystudents. We discussed how I could deal with the situation I met. Finally, I was encouraged and fu

In fact, he becomes a teacher of minebyteaching me the truth of education“The secret to education lies in respecting the pupils.” Thanks tothe help I received from him that first year, I have grown as a successful educator as he is now.
