11、One of the most exciting and publicized uses of 5G is telesurgery (远程手术). This is when a surgeon remotely performs an operation on a patient. They may not be in the same room, nor even the same country! In January 2019, the worlds first remote operation was performed in Fujian province. A doctor con

12、trolled robotic arms through a 5G network to remove the liver of a laboratory test animal.Two months later, China completed its first 5G-based human brain operation between a doctor and a patient located more than 4,000 kilometers away.Team leader Tian Wei told Xinhua News Agency, “The combination o

13、f 5G technology and surgical robots is a huge technological advance that will help us share our skills with more patients in distant regions.”“People across society can now have access to top medical resources. In the future, using robots and 5G will be common.The medical community will be smarter,”

14、 he added.These advances are only possible with 5G.The high speed of the network means there is no significant latency between a doctors movements in one place and a robots in the other.This allows doctors far more precision than on a 4G network. Its the same as playing a computer game online.Slow c

15、onnections mean shaking and unpredictable movements.5G will also bring everyday benefits to healthcare. Before treatment, 5G will support a large number of high-definition (高清晰度的) video calls with doctors and provide immediate advice for those who cant visit hospitals. After being treated, wearable

16、devices will send data in real time to doctors, allowing hospitals to monitor recovering patients at their homes.5G technology aims to ensure everyone has access to good health-care. As 5G is rolled out, we may realize the world where robot operations and home health-care become common.1.Which of th

17、e following best describes 5G technology from Tian Weis words?A.5G will make good health-care available to more patients.B.It is hard to say whether 5G will be widely used in the future.C.5G has great potential in various fields including the community.D.It remains doubtful that doctors use robots a

20、apply 5G to health-care.【答案解析】1.A细节理解题。根据第三段中的“The combination of 5G technology and surgical robots is a huge technological advance that will help us share our skills with more patients in distant regions.”可知,5G技术与手术机器人的结合是一项巨大的技术进步,这将有助于医生和更多偏远地区的患者分享他们的技能。再根据第四段关键句“People across society can now ha

21、ve access to top medical resources.”可知,全社会的人现在都可以获得顶级医疗资源。由此可推断出,从田伟的话中我们可以得知,5G技术将为更多的患者提供良好的医疗保健。根据这些信息可以判断B项“很难说5G是否会在未来被广泛使用”和D项“医生使用机器人和5G技术进行手术仍然不太可能”错误。田伟没有提及C项“5G在包括社区在内的各个领域都有巨大的潜力”。故选A项。2.B词义猜测题。画线词所在句子的句意为: 网络的高速意味着医生在一个地方的动作和机器人在另一个地方的动作之间没有明显的_。根据常识可知,5G网络相比于4G,速度大大提高了,也就是减少了延迟,可推断出医生和机

22、器人的动作之间没有明显的延迟。This allows doctors far more precision than on a 4G network.(这使得医生比用4G网络更精准)也可以表明,5G网络减少了动作的延迟,所以才会更精准。delay意为“延迟,延时”,符合语境。A项“匆忙”、C项“速度”以及D项“失误”不符合文意。故选B项。3.C推理判断题。根据倒数第二段中的“Before treatment, 5G will support a large number of high-definition (高清晰度的) video calls with doctors and provid

23、e immediate advice for those who cant visit hospitals.”可知,在治疗前,5G网络将支持大量与医生的高清视频通话,为那些不能去医院的人提供及时的建议,由此可知,远程医疗给不能去医院的病人提供了方便,也使医生为病人诊断更加方便,也就是说,远程医疗对病人和医生来说都更加方便。故选C项。4.C主旨大意题。通读全文可知,文章通过远程手术的例子,说明了5G技术的方便快捷让远程医疗成为可能,并为社会带来巨大福利。再根据文章最后一段中的“As 5G is rolled out, we may realize the world where robot op

24、erations and home healthcare become common.”可知,随着5G技术的出现,机器人手术和家庭医疗保健会变得很普遍。由此可推断出,文章主要讲的是5G技术在远程医疗上的意义。A项“如何利用5G技术做手术”;B项“使用5G技术的重要性”;D项“不同国家如何将5G应用于医疗保健”。故选C项。II.七选五根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。Fruits Are Less Fattening Than OthersHealth authorities recommend food with added sugar be l

31、ting whole fruit means absorbing less sugar and calories F. Fruit sugar is a natural sugar that has little effect on blood sugar G.

32、 hard to，可知前一句一定是与之相反的内容，故答案选G项。3. F。考查细节句。根据后提示 so it is often recommended to diabetics precisely（所以它经常被准确地推荐给糖尿病患者 ）可知与F项中的has little effect on blood sugar 呼应，答案选F项。4. D。考查细节句。根据前提示Taking in too much sugar means taking in too many calories（吸收太多的糖就意味着吸入许多卡路里）可知其与体重上升和储备脂肪相关，故答案选D项。5. A。考查细节句。考查主题句。

33、根据后提示Something that may be harmful in high amounts may be harmless or beneficial in small amounts（一些东西量大时可能有害的，但量小时可能无害或有益）可知与A项相呼应，故答案选A项。.语法填空阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。Genome editing brings many exciting possibilities.1is well-known to you, genes play a critical role in shaping our lives, an

38、 trying考查动词时态。空处动作表示遗传学家的努力已经开始,并且一直在进行,所以用现在完成进行时。3.an考查冠词。means意为“方式,方法”时为可数名词,单复数同形,形容词effective以元音音素开头。故用不定冠词an。4.leading考查现在分词。空处表示前面造成的自然而然的结果,故用现在分词作结果状语。5.with考查with的复合结构。此处是“with+宾语+现在分词”构成的复合结构,在句中作状语。6.appropriately考查副词。空处修饰动词use,作状语。故用副词形式。7.to wrestle考查不定式。start to do sth.表示“开始去做某事”。8.p

39、utting考查动名词。mean doing sth.表示“意味着做某事”。9.is考查主谓一致及时态。此处为there be句型,主语为much,且陈述一般事实,故设空处用一般现在时,be动词用单数形式is。10.greatest考查形容词最高级。根据语境及此处结构“one of the.”可知,空格处用形容词最高级。IV. 写作假定你是星光中学学生会主席李华，你校组织了一场关于抗击冠状病毒的校园安全讲座， 请你就此写一则通知。内容包括：1讲座的时间、地点；2讲座的主要内容；3其他注意事项。注意：1.词数100左右；2.可以适当增加细节，以使行文连贯。3.参考词汇：新冠病毒COVID-19；
