Microwaves may be great at warming up food, but what about warming people?
Using microwaves to directly heat owners of a room would save much of the energy wasted by heating walls and furniture. And despite popular ideas about microwaves, this technique would be safe, according to Charles R. Burlier of the Microwave Research Center in Marlborough, New Hampshire. Low-power microwaves only penetrate (贯穿) the skin (low-power microwave penetration in a ham is about 0.2 inches, for example) and with no negative effects.
To test this idea, Buffler subjected himself to microwaves in a special room using a standard 500-watt, 2459 MHz magnetron (磁控管). He found that a person will start to feel warmth at about 20 kilowatts per square centimeter (mw. / sq. cm. ) ; a satisfactory feeling of warmth occurs between 35 and 50 mw. / sq. cm. By comparison, a person standing in noonday summer sun feels the amount of 85 mw. / sq. cm. And a frozen meat pie in your microwave oven receives about 1000 mw. / sq. cm.
In houses of the future, each room could be provided with its own magnetron, says Buffler. When you stepped into the living room, for example, a motion detector (运动感应器)would turn on the magnetron, filling the room with low-power microwaves. In the same way that a microwave oven heats up a hamburger, but not the plate it’s on, you would feel warmth from the microwaves without changing the temperature of your coffee table. (You could, however, make your favorite easy chair even more comfortable by treating it with a radiation-absorbing chemical.)
While it might be some time before homeowners are comfortable enough with the idea to set up whole-body microwave heaters in houses, Buffler says microwaves may attract livestock(家畜) farmers. Lambs that are born outdoors in winter, for example, are frequently lost to cold. Microwaves could warm the lambs safely and quickly.

阅读下面的短文，然后按照要求写一篇150词左右的英语短文。
The Nigerian postal service has witnessed a reduction in the number of letters sent, especially by individuals, due to the alternatives of email and text.
“People prefer these over letters, because of the speed, although letters serve many purposes, other than conveying of messages", said Barry Varley Tipton, principal of Cherry Field College.
But some people think that the vanishing(逐渐消失的) art of letter writing has grave (严重的) consequences for students, teachers, the economy, society and the beauty of reading from loved ones, because letters in those days usually had a variety of styles .
A lover of letters writing, Hajiya Aisha refers to the occasions she has seen people enraged, because their connections at a cyber cafe took 56 seconds rather than the usual 36 hours. She says, “Although letters are slow, waiting for something good is not wholly a bad thing. Nothing beats a hand written letter.”
"When I was a graduate studying overseas twenty five years ago, my mother wrote to me daily. It was wonderful to receive those letters. They often said nothing more than everyone was thinking of me. I continue this tradition with several friends who are scattered worldwide. Hand written letters show the love that we have for family and friends. Email cannot replace the smile of actually getting the letter. The warm, sincere thank- you note, or the sweetly scented love letter we usually received and sent in those days is irreplaceable" she said.
Will electronic age stamps replace letters? Hopefully not, since it takes with it a culture rich in colour, history, and communication. Letters, like bits of ourselves, deserve to be stored away for future readers, giving them insight into details as small as the price and pattern of stamps, and as great as personal insights exchanged long ago.

下面是对这几本书的简要介绍，请把它们对应的封面信息找出来：
1. In this collection, Bill Bryson is writing from home. We find he assesses life both in New England and in the contemporary United States. With the telescopic perspective(远望视角) of one who has stepped out of the American mainstream and come back after 20 years, Bryson holds the mirror up to U.S. culture and feel strange to his motherland.
2.This book is a guide to the world’s unspoilt sights and experiences. It presents one thousand fresh and fascinating alternatives to hundreds of well-known tourist destinations and sights, including alternatives to the Carnival in Rio and the beaches of Thailand, the most-visited national parks, over-rated restaurants and holiday sites.
3.Returning to the U.S. after 20 years in England, Bill Bryson decided to reconnect with his mother country by hiking the length of the 2100-mile Appalachian Trail. Awed by merely the camping section of his local sporting goods store, he still goes into the wilderness and learns hard lessons about self-reliance.
4. A travelogue by Bill Bryson is as close to a sure thing as funny books get. This book is no exception. Following an urge to rediscover his youth, the author leaves his native Des Moines, Iowa, in a journey that takes him to across 38 states in the country, which is like a small town in his opinion.
5.Born in Iowa, Bryson backpacked through Europe as a young man. While living in England some 20 years later, he revisited many of the same places from arctic Norway’s northern lights to romantic Capri in Italy. Here he jumps back and forth between old memories and new experiences.
