　　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.

　　11．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.

　　12．How will computers sense users' moods?

　　A．Through a screen.

　　B．Through a keyboard.

　　C．Through the voice of users.

　　D．Through multi­modal interfaces.

　　13．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

　　14．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 2017 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.”

　　15．This passage is most probably taken from ________.

　　A．an instructive brochure

　　　B．readers feedback

　　C．a news report

　　　D．a brief introduction

　　16．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.

　　17．The underlined word “it” in Paragraph 5 refers to________.

　　A．the device

　　　B．the system

　　C．the phone

　　　D．the battery

　　18．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
