Q: Article: What is funny? The short answer is: Who knows? The joke that causes a burst of laughter from one listener might be met with a puzzled look from another. In general, you should avoid jokes at any business or social gathering where there are more than two people in your conversational group. If there are only two people -- and they consist of you and your best friend -- go ahead and tell it. Admittedly, a few people possess a perfect sense of timing, appropriateness, and joke delivery. You are probably not one of them. You might be quite funny and have many great jokes. But there's a place for jokes -- over dinner with family, hiking with friends, but business or social affairs with colleagues and acquaintances are not it. It takes a whole other level of joke-telling ability to put a joke into the more formal conversations. The best jokes come into the conversation so that by the time listeners realize a joke is in progress, the punchline that produces humour is being delivered -- to their surprise and delight. Jokes don't translate well when you're in a group with mixed backgrounds: those whose first language is not English, those who might not understand a special term or an "in" expression, young people who wouldn't catch a reference to some bit of culture familiar to older people -- and vice versa . Never joke about another person in the group -- about their name, habits, hometown, profession, appearance, or past. It's not a question of whether the joke is cheery or appropriate. No one enjoys being singled out this way. When you are the subject of the joke, the laughter doesn't feel good no matter how hard you try to tell yourself they're not laughing at you. Because that's what it feels like. What do you say if you realize your joke upset someone? Apologize as briefly and as sincerely as you can, and hope that someone changes the subject. Try saying: "I'm sorry. I should have known better" or "I'm sorry. I wasn't thinking." What do you do if people don't get your joke or don't appear to find it as funny as you do? First, do not retell it, only louder this time, hoping the point of the joke will be seen. Second, don't try to push people to get it. People do not like people whose jokes they don't understand. They feel stupid and need to blame someone. If you want to leave with the goodwill of your listeners, say something to make them feel less foolish. You could say: "I don't know why I tell jokes when I'm so poor at it." The world needs laughter, and good humour is a success wherever it goes, so this caveat about joke-telling is not meant to dampen high spirits or to advocate dull conversation. If you're a gifted story-teller and you know people love your jokes, go for it. We need your kind. The rest of us will save our jokes for family and close friends.

Q: Article: Clothes can make phone calls, play music, dial your pal's number, keep you warm during cold weather and operate your computer? This is not a fantasy. A British company, called Electrotextiles, has created a wide range of clothes -- clothes that have minds of their own! Scientists, working for the company, have invented a kind of fabric that can be blended with flexible electronic materials to create intelligent clothing. The result are electronic garments. If you think the wearer has to be wired to different devices, think again. These designer clothes are wire-free, soft to touch and washable!! Like any electronic device, these high-tech clothes have to be powered. Currently, a tiny nine-volt battery serves the purpose. But the researchers hope that in the near future the clothes will generate electricity by using body heat. These clothes are 100 percent shock proof, they say. The Electrotextiles team has also created the world's first cloth keyboard. This keyboard can be sewn into your trousers or skirt. To use this device, you will have to sit down and tap on your lap! These 'lap- tap' gadgets are all set to take over laptop computers! Another useful garment is the shirt-cum-mobile phone. This handy invention enables drivers to chat comfortably with others at the wheel! Other popular electronic wear include the denim jacket with flexible earphones sewn into the hood and the electronic ski jacket with a built-in heater. The ski jacket is also programmed to send signals to a satellite. This technology is known as global positioning system and can be used to track lost skiers and wandering kids. Having completed the cloth keyboard, scientists have already started to work on a new project--a necktie that can be used as a computer mouse. What is the next? Do you have any idea?
Answer: they use electricity as power

A: . The electronic garments are similar to other electronic devices in that _ .

Q: Article: Before you leave for the airport Ensure that you have your passports (and any necessary visas), tickets and money in your hand luggage. If packing medicines, ensure that they are in their original packaging as this will avoid delays or prevent them from being taken away at customs. Do not wrap presents as they may have to be unwrapped by security staff or customs. The Department of Health has devoted a section of their site to health advice for traveling abroad.

You should arrive there 2 hours before the take-off for international flights and one hour before the take-off for domestic flights.

If taking a taxi, ensure that the firm you intend to use has taxis available at the time you wish to travel. At the airport Be aware that increased security has considerably lengthened the time it takes to go through check in and security. Make sure you keep your baggage with you at all times and alert any member of airport staff to any unattended package. Never look after baggage belonging to other people or carry anything onto the aircraft for someone else. Keep a close eye on the display boards announcing which gate flights depart from. In the air If on a long flight, move your feet around, or get up and walk around regularly if you can. Avoid dehydration by drinking plenty of water or other non-alcoholic drinks. Don't eat too heavily before or during a long flight as this will help to avoid indigestion and hypertension .
