Exercise is an important part of a healthy life. It reduces your risk of heart attack and is a good way to control body weight. It is also something you can do with other people, which can be great fun. So, it is important to find time to exercise and be healthier. As well as making time to exercises, another way is to build it into the natural rhythm of your day. * Go for a walk on your lunch break. Try to find at least three different ways and change them throughout the week. It might even be possible to find a place to walk inside, for those bad weather days. * Talk to your employers about improving health at work. Encourage your workers to cycle to and from work. You might also be able to encourage them to set up a gymnasium. Sell the idea by pointing out that doing so will improve productivity , and make workers happy. * If you are a student. Go for walks with friends to talk about your studies. Spend some time in the learning resource centre reading about sport, exercise and health. The more you know, the more choices you will have about how to be physically active. Most colleges have sport and exercise programs that students can take part in. Find out which activities are being held, and try those you think you might enjoy. We can learn from the passage that _ . A) walk is most suitable for those who work indoors B) one who knows more about health will be healthier C) exercising with others will be better for one's health D) combining exercise with daily work can save time to keep healthy

Lee's mother Sun became unexpectedly pregnant while married to a disabled man. Doctors told her that because of a medication she had been taking her child would not be normal. She chose to continue with the pregnancy and in 1985 in Seoul, South Korea, little Hee Ah Lee was born with only two fingers on each hand, disfigurement of her legs, and slight brain injury. The hospital told Sun that she could not care for the child at home and her relatives wanted her to place the child for adoption in a foreign country. Sun, however, thought her baby would live a successful life. When Lee was a pre-schooler, Sun wanted her daughter to take piano lessons for two reasons. One was that she felt it would help her strengthen her hands so she could hold a pencil. The other was that she felt that if she could master the piano, she could master anything. For six months piano schools turned them down and then the one teacher who did accept the task got discouraged and wanted to quit. It was a three-month contest of wills between mother and daughter that led to a conflict in which Sun actually threw her daughter on the floor in frustration. But Lee got back up on the piano bench and for the first time played a children's song. That was the turning point and one year later Lee won the grand prize in a piano concert for Kindergartners. It was at the age of 7 that Lee won Korea's 19th National Handicap Conquest Contest and was presented with her award by the President of Korea. Lee has won numerous awards, and is a widely traveled concert pianist with more than 200 appearances. Her first album titled "Hee-ah, a Pianist with Four Fingers" was released in June, 2008. Lee speaks highly of her mother for challenging her to master the piano and said that although her training was difficult, "As time went by, the piano became my source of inspiration and my best friend." What was probably in Lee's mind when on the floor? A) Learning piano was too difficult for her. B) Life was unfair to her. C) She would try her best to learn piano. D) Her mother didn't love her any more.

Q: Communications technologies are far from equal when it comes to conveying the truth.The first study to compare honesty across a range of communication media has found that people are twice as likely to tell lies in phone conversations as they are in emails.The fact that emails are automatically recorded--and can come back to puzzle you---appears to be the key to the finding. Jeff Hancock of Cornell University in Ithaca, New York, asked 30 students to keep a communications diary for a week.In it they noted the number of conversations or email exchanges they had lasting more than 10 minutes, and confessed to how many lies they told.Hancock then worked out the number of lies per conversation for each medium.He found that lies made up 14 per cent of emails, 21 percent of instant messages, 27 per cent of face-to-face interactions and an astonishing 37 percent of phone calls. His results to be presented at the conference on human-computer interaction in Vienna, Austria, in April, have surprised psychologists.Some expected emailers to be the biggest liars, reasoning that because deception makes people uncomfortable, the indirect contact of emailing would make it easier to lie.Others expected people to lie more in face-to-face exchanges because we are most practiced at that form of communication. But Hancock says it is also crucial whether a conversation is being recorded and could be reread, and whether it occurs in real time.People appear to be afraid to lie when they know the communication could later be used to hold them to account, he says.This is why fewer lies appear in email than on the phone. People are also more likely to lie in real time---in an instant message or phone call, say---than if they have time to think of a response, says Hancock.He found many lies are spontaneous responses to an unexpected demand, such as: "Do you like my dress?" Hancock hopes his research will help companies work out the best ways for their employees to communicate.For instance, the phone might be the best medium for sales... According to the passage, why are people more likely to tell the truth through certain media of communication? A) They are afraid of leaving behind traces of their lies B) They believe that honesty is the best policy C) They tend to be relaxed wh en using those media D) They are most practised at those forms of communication

The world's biggest Internet search engine, Google, has proven once again to be King of the Web. Users can download "Google Wi-Fi" software and then enjoy free Wi-Fi service available in some US cities since last Tuesday. Wi-Fi is short for "Wireless Fidelity" . It allows laptop computers and personal digital assistants to the Internet at high speed by radio signal. A person with a Wi-Fi enabled computer can connect to the Internet when near one of the network's access points. The place covered by one or several access points is called a hotspot. Google has already set up two "hotspots" in the US city of San Francisco which provide a free Wi-Fi service. The Wi-Fi technology even allows users to enjoy a free Internet phone service. Some scientists argue that Wi-Fi may replace mobile phone networks. Wi-Fi is still limited to a few cities, where there are "hotspots". But its capability of sending information has already done better than that of the mobile phone network, even that of 3G(Third Generation Telecommunication Technology). Some scientists have started to call Wi-Fi 4G. In addition to a high speed Internet connection, Wi-Fi has other advantages compared to mobile phones. Wi-Fi is global. The same Wi-Fi system works in different countries around the world. Different from using cell phones, you don't need to change computers to use Internet phones when you go to other places and most importantly, many Internet phones cost you nothing at all. Wi-Fi is not available in cities without _ . A) a computer B) a radio C) a cell phone D) a hotspot
