A Northern Ireland team is leading a research to develop a thinking computer which can sense a user's mood.Researchers at Queen's University in Belfast hope to complete the 10 million Euro project for an emotionsensitive computer within four years.
The aim is to enable computers to think and behave more like humans.The Europewide project is being led by the university's School of Psychology and involves 160 researchers from 27 institutions.The university's researchers developed the scheme and signed the contract with the European Commission.The academics said the work will build upon attempts to create “multimodal interfaces (多模式界面)” which allow machines to sense and respond to the moods of the user.
Programme leader Professor Roddy Cowie said while it sounds like science fiction, computers which respond to human emotion will appear in the future.“At the moment, our use of computers is limited by the fact that we need a keyboard and a screen to access them，” he said.“It would make a big difference if we could interact with them by speaking normally—perhaps through a microphone and a transmitter (传感器)．” But emotion is part of normal speech, and experience has shown that most users are deeply uncomfortable with speech interfaces that ignore it—too uncomfortable to use them very much.“If we can make computers more intuitive (富于直觉的) and expressive, and also less challenging to use, there is great potential to let people make fuller use of information technology.”
The emotionsensitive computer would have its own “personality” and establish a social relationship with the user.“It's a fair bet that in 30 years' time, emotionsensitive interfaces will be as much part of life as windowandmouse interfaces are now，” said Professor Cowie.The project team believes such computers will play a major role in teaching and learning.
16．Which of the following statements is TRUE about the project?
A．It aims to create an emotionsensitive computer.
B．It can create a 10 million Euro profit.
C．It is led by a Southern Ireland team.
D．It has been completed within four years.
17．How will computers sense users' moods?
A．Through a screen.
B．Through a keyboard.
C．Through the voice of users.
D．Through multimodal interfaces.
18．We can infer from the passage that a person's emotion________.
A．varies from time to time
B．is determined by his own personality
C．plays an important role in normal speech
D．makes people uncomfortable when one is speaking
19．What conclusion can we draw from the last paragraph?
A．Emotionsensitive computers can talk freely as human beings.
B．It will be difficult for people to use emotionsensitive computers.
C．Emotionsensitive computers have been widely used in teaching.
D．It will be common for people to use emotionsensitive computers in the future.

Fujitsu, a Japanese technology company, has created a system capable of simultaneously(同时地)charging multiple portable electronic devices such as mobile phones, digital cameras and laptop computers without the need for cable connections.
Electric cars users may also eventually be able to charge their vehicles wirelessly using the same technology, said the company, which developed a sample system at Osaka Prefecture University. Claiming to be the world's first of its kind, the technology works on the basis of the transmission of electricity using magnetic fields between the charger and the electronic device.
The system enables wireless charging at distances of up to several meters. With the final aim of installing public “charging spots” on the streets in order to enable easy charging around the clock, scientists at Fujitsu Labs are planning to commercially sell products incorporating the new wireless charging system as early as 2024 but have not yet decided how much they would cost.
“This technology paves the way to integrating compact wireless charging functions into mobile phones and enabling multiple portable devices to be charged simultaneously without any restrictions on their position relating to the charger，” the company said in a statement.
Mobile phone users in Japan can currently charge their batteries using the disposable portable plugin batteryoperated device, available at most train stations and convenience stores. However, phone companies warn long time use of it can damage the phones.
The company added, “We are also looking at applying the results of this work to fields other than portable electronics, including power transmission between circuit boards(电路板)or computer chips，and providing mobile charging systems for electric cars.”
20．This passage is most probably taken from ________.
A．an instructive brochure
B．readers feedback
C．a news report
D．a brief introduction
21．Which of the following can best describe the striking feature of this system?
A．It enables wireless charging at distances of up to several miles.
B．It enables you to charge your device very easily beside the clock.
C．It is wireless and makes multiple charging at the same time.
D．It can be bought at any formal supermarkets in the city.
22．The underlined word “it” in Paragraph 5 refers to________.
A．the device
B．the system
C．the phone
D．the battery
23．The best title for the text would be________.
A．Fujitsu, a famous Japanese company
B．Power transmission between circuit boards
C．New wireless charging system developed
D．Mobile phones damaged by charging
答案
课时作业(八)
Ⅰ.1.D 考查交际用语。句意为：“很抱歉，我未能按时完成它。”“无论如何我还得谢谢你。”D项符合语境。A项为见面打招呼用语；B项在表示委婉拒绝时用；C项在表示非常感谢时用，均不符合句意。
2．C 考查副词辨析。句意：也许，从现在起他真应该多锻炼。不管怎样，我希望他能很快恢复过来。somehow “由于某种原因”；somewhat “有点；稍微”；anyway “不管怎样；无论如何”；anywhere “在任何地方”。故C符合题意。
3．A watch over “照管”。句意为：我去游泳，你帮我看一下衣服好吗？其他选项均不符合句意。
4．B 考查短语辨析。出了重大事故放长假，也就是说(换句话说)，他被开除了。前后句子从逻辑上讲不存在因果关系或者转折关系。
5．A 考查动词的时态和语态。Italian Luca Parmitano 和select 是被动关系，故排除B，C。根据句意，表示过去的动作“已经被选入……”对现在的影响，故用的是现在完成时的被动语态，故选A。
6．A 考查交际用语。由答语中的not me可以看出，他不想去，所以选择A项，这是一句美式俚语，意为“我不喜欢这个东西”或者“它不适合我”。
7．D 考查词汇辨析。as作“随着”解为连词，引导时间状语从句。with 是介词，不能引导从句。
8．A 考查时态、语态和主谓一致。答话人之所以让对方删除手机上要求汇款的信息是因为到目前为止已经有很多人上当受骗，所以用现在完成时的被动语态，排除C、D两项； many a表示“大量”，修饰单数可数名词，谓语动词用单数，故排除B项选A项。
9．C 考查as a result的用法。as a result意为“因此，所以”，单独使用，表示后句是前句的结果；而however表示转折，moreover, furthermore表示递进，不符合语境。
10．D 考查such a＋adj.＋n＋that结构。注意，如果把A项中的a 放到wellknown后也是正确的。
11．C 主要考查在交际用语中动词的时态及语态。根据主语与谓语动词的关系可知是被订购，于是排除选项A；选项B表示将要发生的事情；选项C表示已经发生的事情；选项D表示过去某个时候即将发生的事情。根据前面的That's too bad.可知，事情已经发生，故答案为C。
12．B 考查副词辨析。句意为：当一个人得到了物质财富后，他一定会寻求精神享受，这是一个被大家所普遍接受的真理。partly “不完全地，部分地”；universally “普遍地”；particularly “尤其，特别”；previously “先前，预先”。语意表示这是被大家所普遍接受的真理，因此选B。
13．D 考查交际用语。句意为：“恐怕我不能像计划得那么快完成任务。” “别急，慢慢来。”I'm afraid为委婉的说法，不用Don't be afraid来回答；Don't mention it用来回答道歉；I suppose so表示“我想如此”，相当于I think so，不符合语境。Take your time表示“别着急，慢慢来”，符合句意。
14．D 考查短语用法。deal with通常与how搭配；do with通常与what搭配。C项语序不对。
15．C 考查时态。从句意知“过去十年来他一直都在发掘他最大的潜能”，另外，从“in the past decade”可知应该用现在完成时，同时此处强调十年来他一直保有的状态，所以用现在完成进行时，故选C。
.A
北爱尔兰的一个研究小组正在研究一种会思考的电脑，这种电脑能够感知使用者的情绪。
16．A 细节理解题。根据文章第一段第二句可知A项正确；B项的profit错误；C项的Southern错误；D项说项目已经完成，这一点不对。
17．D 细节理解题。根据文章第二段最后一句可知D项正确。
18．C 推理判断题。根据第三段中倒数第二句“…experience has shown that most users are deeply uncomfortable with speech interfaces that ignore it—too uncomfortable to use them very much.”可知C项正确。
19．D 推理判断题。根据文章最后一段“It's a fair bet that in 30 years' time, emotionsensitive interfaces will be as much part of life as windowandmouse interfaces are now…”可知D正确。
B
本文是一则科技资讯，主要介绍了一家名叫富士通的日本科技公司发明了一种可以同时多任务充电的无线充电系统。
20．C 文章出处题。从全文内容可知，本文是介绍最新无线充电系统的一则科技类资讯，所以答案选C项。
21．C 细节理解题。从文章第一段中的“…a system capable of simultaneously(同时地)charging multiple portable electronic devices…without the need for cable connections.”可知，该设备的特点：一是无线，二是可同时多任务充电，故答案选C项。
22．A 代词指代题。从倒数第二段的最后一句可知手机公司警告人们长期使用它会损害手机，由此可知it指代上文的“the disposable portable plugin batteryoperated device”，选A项。
23．C 主旨大意题。从全文可知，本文主要介绍了一款可以同时 多任务充电的无线充电系统，故C项最能概括全文内容。
