Her mother,Divya Gupta had a suggestion:write an app.She was half-kidding,but Medha took the challenge seriously.So she went to work. The result was Safe Travel,an app designed by Medha to help walkers feel more secure when travelling alone.Using the iPhone,a person can program it to send a warning to someone he or she trusts if he or she fails to arrive at a destination within a certain time. It was the first iOS app that Medha had created.While she didnt think much would come from the project,her effort caught the eye of judges for the annual Congressional App Challenge,who selected her as the winner for Virginias 10th District. The App Challenge is designed to encourage students to consider careers in science,technology,engineering,and math by experimenting with coding and computer science.Winning students are invited to attend a reception on Capitol Hill in April and also received $250 in Amazon Web Service credits. Medha said it took her about 40 hours to design,program and test the app.As for her next app?Medhas not certain.She temporarily has her app-development ambitions on hold because shes busy teaching herself artificial intelligence to help deal with improper words on Facebook.Yes,she knows that there are teams of engineers probably doing the same thing.But she figures it cant hurt her own part,too. “If we see something wrong with the world,we should do something about it,”she said.“After all,the only one stopping us from doing something is ourselves.” 【语篇解读】本文是一篇记叙文,主要讲述了 Medha Gupta 设计一款手机应用程序的经历。 1.Why did Medha Gupta feel worried? A.It took a long time to walk home. B.It was colder than ever in winter. C.It was unsafe to walk home alone. D.It was difficult to write an app. 答案 C 解析推理判断题。根据首段的叙述和第三段首句可知,Medha 有时候担心自己放学回家时的安全问 题,因此她设计了应用程序 Safe Travel,它能够使出行者独自外出时感觉更安全。 2.What does the underlined phrase “on hold” in Paragraph 6 mean? A.Delayed.B.Developed. C.Suspected.D.Satisfied. 答案 A 解析词义猜测题。 根据画线词后的“because shes busy teaching herself artificial intelligence to help deal with improper words on Facebook”,再结合画线词前一句“Medhas not certain.”可推断出她暂时 把程序开发的目标推迟了。 3.What is Medhas attitude to the challenge? A.Curious.B.Sensitive. C.Uncertain.D.Optimistic. 答案 D 解析推理判断题。根据第二段“but Medha took the challenge seriously.So she went to work.”可知,她很 认真地对待这个挑战,并开始着手工作,这表明了她面对挑战时的乐观态度。 4.Whats the main idea of the text? A.Medha registered for the App Challenge. B.Medha designed Safe Travel successfully. C.The App Challenge directs students to choose careers. D.An app guides walkers home. 答案 B 解析主旨大意题。本文是围绕 Medha 设计一款手机应用程序 Safe Travel 展开的,讲述了她的设计初 衷、过程以及成就。所以 B 项是最佳选项。 B China will green light Internet medical services conducted by medical institutions as part of a broader push to promote Internet Plus Healthcare,those at a State Council executive meeting chaired by Premier Li Keqiang decided. Medical institutions will be allowed to provide online diagnostic services for some common and chronic diseases in patients follow-up visits to their doctors.The top levels of hospitals will be encouraged to provide online services,including consultations (会诊),reservations and test result inquiries. As China joins the ranks of middle-income countries,the demand for health services has increased accordingly.Internet Plus Healthcare can help reduce the problem of inaccessible and expensive public health services that have long been a big concern for the general public. One decision coming out of the meeting says the intelligent review for health insurance will be applied and the one-stop settlement will be advanced.The real-time sharing of prescription and drug retail sales will be explored,as well. “We must waste no time in pushing forward the measures once the decisions made.” Li said.“In recent years,top-level hospitals in major cities have seen steady increases in the number of patents.Medical bills have become a heavy burden on families and high-end medical resources still fall short of meeting the growing demand of the public.” To solve the problem,a two-pronged (双管齐下的) approach must be taken.One is to establish medical partnerships to strengthen cooperation between major hospitals and community clinics.The other is to bring forward Internet Plus Healthcare to promote the sharing of quality medical resources. The government will see to it that long-distance healthcare services cover all county-level hospitals.So more efforts will be made to ensure that high-speed broadband network will be extended to cover medical institutions in urban and rural areas.Dedicated Internet access services will be set up to meet the needs for long-distance healthcare services. 【语篇解读】本文是一篇说明文。文章主要是关于中国政府计划开展绿色互联网医疗服务的 详细内容报道。 5.According to the text,which of the following services wont a patient enjoy online? A.Receiving a medical operation. B.Asking doctors for advice after the test. C.Several doctors discussion about the disease. D.Making an appointment with a doctor in advance. 答案 A 解析细节理解题。根据文章第二段最后一句“The top levels of hospitals will be encouraged to provide online services,including consultations,reservations and test result inquiries.”可知,病人获得的在线服务 包括会诊、预约和结果咨询,所以只有 A 项没有涉及。 6.Why is the demand for health services increasing in China? A.The expense of medical care. B.The recognition of health insurance. C.The improvement of peoples life quality. D.The inconvenience of hospital equipment. 答案 C 解析推理判断题。根据文章第三段第一句“As China joins the ranks of middle-income countries,the demand for health services has increased accordingly”可知中国人民的生活质量已经提高了。 7.What can be the suitable title for the text? A.Modern Hospitals B.Online Healthcare on its Way C.No More Burden for General People D.Wide Applications of Internet Service 答案 B 解析标题归纳题。根据文章的首段和尾段可知互联网医疗服务正在发展中,方兴未艾。 .七选五 Self-driving cars are believed to be the future of driving.Companies including Toyota,Uber and Google are all competing to be the first to bring them to the market.However,carmakers need to solve one problem first:1 Most drivers today use gestures to show their intentions.They wave a car into a lane,or nod at passers-by and cyclists,to let them cross.2So what can they do?US carmaker Ford and its partner Virginia Tech think they have the answer,according to Business Insider. 3For example,if a driverless car is giving way,it could flash two white lights side to side.A solid white light would tell people nearby that there are no humans in the car.A slow blinking light would show the car is coming to a stop.4To test the method on real roads,the team designed a special suit that looks exactly like a car seat.When a driver wears it,it looks like the car is driverless. The team successfully collected more than 1,500 hours of data after about 2,900 kilometres of “self- driving” through busy cities.5Ford says it plans to share the data with 11 other carmakers,according to DOGO News.Ford hopes that in the future,every carmaker will use the same system of signals. A.But self-driving cars dont have this ability. B.Its a test for the companys self-driving technology. C.The data recorded how people interacted with a driverless vehicle. D.How driverless cars communicate with passers-by,bikers and other drivers? E.A rapidly flashing light would tell passers-by that a car is about to speed up. F.More than one-third of them are worried about the safety of self-driving cars. G.The team is testing the method that uses light signals to show what self-driving cars are. 答案与解析 【语篇解读】本文是一篇科技报道说明文,向读者介绍了无人驾驶车辆如何利用灯光和周围的 人与物以及其他司机进行沟通。 1.D第一段是全文的总领,下文主要介绍了无人驾驶车辆如何与过路人以及其他司机进行沟通。 2.A上文提到,大多数司机可以用手势来向他人示意。下文中又指出“So what can they do?”,故可推 断此处是将无人驾驶车辆与大多数司机进行比较,空格处是指无人驾驶车辆没有这项技能。 3.G根据本段内容可知,本句是本段的主题句,且上下文谈论的是无人驾驶车辆利用灯光信号与周围 的人进行沟通。 4.E空格处上一句讲的是慢闪灯的示意,故可知此处是与上文慢闪灯做比较。 5.C空格处承接上文,进一步解释了这些数据是记录人们怎样与无人驾驶车辆进行互动交流的。 -1- Unit 3 The world of science 晨读晚诵 XiaomiMiBand4,whichisthelatestsmartfitnessbandfrom Xiaomiisjustacoupleofmonthsold.Thewearabledevicewas announcedinJunethisyearwithabiggercolourdisplay.Itisdesigned withtheabilitytotrackvarioussportmodesincluding walking,cycling,swimming,exercise,outdoorandindoor running.Besides,itcanrecognisedifferenttypesofswimmingstrokes.
