While people will always be the best caregivers for people,there just aren't enough people. That's where robotic technology can really make a difference," says Professor Maja Mataric at the University of Southern California. Her group is developing robots to work with stroke patients and elderly people. The research team has found that people react well to a robot gym instructor,and seem to get less frustrated with it than with instructions given on a computer screen. The robot can act as a perfect trainer,with infinite patience. "People say things like 'I prefer this robot to my husband!Can I take it home?'" according to Professor Mataric. "In fact there's a really important point here. As we create these care giving technologies,we're helping not only the people that need the care,but also the people caring for them. We can give them a break,and help them avoid _ ." People are going to have to like,and importantly trust robots before they welcome them into their homes,and several groups around the world are working on making it easier to communicate with them. Much of human communication takes place through body language. Gestures, eye contact , and concepts of personal space are all things that robots are being taught. In learning about how people interact with machines,researchers are also discovering new roles for robots in our lives. Robots can communicate with humans in ways that other technologies can not. "If someone finds the robot to be more persuasive and more reliable,that's going to affect how they interact with it," says Dr Cynthia Breazeal, director of the Personal Robots Group at the Massachusetts Institute of Technology. "We can now start to think about fields where it's the social interaction,which is the main means by which a robot helps someone." Dr Breazeal says that means robots could be used in education,learning,and health care,where social... Question: The scientists are presently working hard to help robots _ . Options: A: to use less electricity B: to communicate better C: to react more quickly D: to have more functions

(Question)
Read the article and select the best answer. Article: A "blogger" is a person who writes on an Internet computer Web site called a "blog ".The word "blog" is a short way of saying Web log, or personal Web site. Anyone can start a blog, and they can write about anything they like. There are millions of blogs on the Internet today. They provide news, information,advertisements, advice and ideas for many people who read them. They contain links to other Web sites. And they provide a place for people to write about their ideas and react to the ideas of others. A research company called Perscus has studied more than 300 Web logs. It says that blogs are most popular with teenage girls. They use them to let their friends know what is happening in their lives. The study also says that more than 100,000 bloggers stopped taking part in the activity after a year. However, some people develop serious blogs to present political and other ideas. For example, the Republican and Democratic parties in the southern state of Kentucky recently started their own blogs. And American companies are beginning to use blogs to advertise their products. At the same time, some long-standing blogs have ended. Last week, blogging leader Dave Winer closed his free blog service "weblogs. com". He says the site became too costly to continue. He started the blog four years ago. And thousands of people had written on it. They are now upset because they did not know that the site was closing. One blog that is still going strong is called Rebecca's Pocket. Rebecca Blood created the Web-site in 1999. She wrote about the history of blogs on the site. That article led to a book called "The Weblog Handbook". It has been translated into four languages so far. Ms. Blood says Rebecea's Pocket gets about 30,000 visitors a month. She writes about anything and everything -- politics, culture and movies. She recently provided medical advice. And she wrote about how to prevent people from stealing money from on -line bank accounts. Question: What is the author's attitude toward blog? Options: A: Objective B: Sceptical C: Disapproving. D: Sympathetic.

Question: Read the article and select the best answer. Article: London has a new magazine.However,it is not printed on paper any more.Everyone who has a television can receive it because it is already on TV! In order to read this magazine,you need to have a decoder.Each page of it is numbered,so you have to dial a number to choose which subject you want to read about.You have a wide choice of topics to choose from-everything from cooking to the latest news. If you want to read some news,the first thing you have to do is to check at the index page which has an easy-to-remember page number,1 00 for example.From page 100,you can then choose from the news articles on page 101 to 109.From here,you will have to key in the numbers again.Then,the news will appear written across your screen.If you want to go out in the afternoon,you can press 181,and a brightly color1ed weather map will appear on the screen.But if you want to buy some cheap things,you can press 162 for a list of the week's best bargains.And whether you should drive or just take the train,you can simply press 189 for the traffic report.This new magazine on TV is very simple to use.But probably,the best thing about the service is that is being updated all the time.Journalists type new materials directly onto screen and the page of the magazine is replaced in minutes. London already has three services.One,transmitted by ITV ,is called ORACLE while the other two,on BBC,are called CEEFAX because they let you see facts.Although CEEFAX and ORACLE have been operating for some time, they have not been well publicized.BBC engineers do not think that their idea will ever replace books and newspapers because this new invention can't be taken with you wherever you go.But many people would agree that this is a breakthrough as great as the invention of printing, which could change not only our reading habits but also our lifestyles. Question: Which is the best title of the passage? Options: A: How to Read a Magazine B: A New Magazine C: An Invention of Printing D: Magazines in London
