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

[EX Q]: Article: What is politeness? This sounds like a simple question. In daily life, we often make judgments about what is polite and what is not polite. For example, to offer your seat to the elderly on a bus is considered polite behavior, and to interrupt when someone is talking is considered impolite; to greet someone the first time you meet him in the morning is polite and to stand up to reach for the dish you want at a dinner table is impolite. So politeness can first of all be regarded as a phenomenon, an observable social phenomenon. What I would like to propose is that as an observable social phenomenon, politeness is something superficial, but to account for what is understood at the surface, we should dig into the depth where different cultural values are rooted. When being complimented , an English-speaking person would readily accept the compliment by saying something like "Thank you" to show his appreciation of the praise, but a Chinese speaker would try to deny the truth of the compliment. They both think they are behaving properly. Yet neither of them would think the other is being polite. The English speaker is being polite to the extent that by accepting and showing appreciation of the compliment, and he avoids hurting the positive face of the person who makes it; the Chinese speaker is showing modesty by _ himself, ignoring the fact of the compliment paid to him. As has been mentioned, self-denigration has been at the core of the Chinese understanding of politeness for over two thousand years. The Chinese, in order to show modesty, will go to such lengths as to underrate what he himself has achieved and deny the truth of a complimentary remark.

[EX Q]: Article: Squawk! Polly wants a cracker! Pretty bird! Pretty bird! These are just a few of the things you might hear coming out of a parrot's mouth. Although parrots seem to be able to talk, they're not really talking like humans. They're not choosing and saying words with specific meanings. Instead, they're simply imitating sounds they've heard. Repeating sounds they've heard before-often many times-is called mimicry. The "talking" we hear from parrots can consist of imitations of all sorts of sounds, from spoken words to creaking doors to barking dogs. They're not really "talking", but it doesn't mean that parrots' mimicry isn't impressive. Did you know that parrots don't have vocal cords like humans? It's true! Instead, parrots use muscles in their throat to direct airflow through their mouths to mimic the sounds they hear around them. Parrots, such as African Greys and Amazons, aren't the only birds that can learn to imitate sounds, including human voices. Some other birds known for their ability to "talk" include Indian Ringneck Parakeets, Budgies and Cockatiels. If you're wondering why some birds imitate sounds they hear, it's because they're social animals. They feel a need to be able to interact with those around them. When kept as pets, these birds see their owners as their family and want to communicate with them. Since a human owner usually can't learn a bird's "language", the bird instead tries to learn the language of its owner. Although these birds are often quite intelligent, imitation is still the best that they can manage. Mimicry becomes a way for them to get attention and interact with their owners. If you want to have a bird that talks as a pet, the best thing to do is to find a bird that already knows how to imitate sounds. Even if a bird knows how to imitate a few sounds, though, you'll still need to spend lots of time training it and providing positive interactions to encourage more "talking ".
