What is the difference between developed and developing countries? The question is quite a difficult one. But we can compare them in two important as?pects: people and economy.

  People In developing countries there are high rates of both birth and death. Families decide to give birth to more than one child,because many developing countries do not have the systems necessary to guarantee (保证) the life of old people. Raising more children seems to be the only way to make sure that during their later years a person will be taken care of.

  The situation is completely different in fully developed countries. Those countries have low levels of birth and mortality. Low mortality rate is mainly because of the good health care,but low birth rate is due to the fact that support?ing a family with more children is expensive nowadays. Another reason is that more and more women decide to work outside,so there is usually no time and place for a large group of children in their lives. Economy In developed countries,most industries have high levels of technological pro?gress,while the smallest role in the country's GDP is played by agriculture.

  In most cases,in developing countries most GDP comes from agriculture. It is mainly due to the fact that services and many branches of industry are in the stage of development. But they have the potential to develop quickly,be?cause they have many things to improve.

  Of course,the difference between developed and developing countries is not that clear,because some countries might be in the middle of great chan?ges. When a country is in that stage,some data can define the country as a developing one ,but others may show that it is a developed one.

  The Internet company Google is testing its newest high-tech device,Google Glass. The company describes the glasses as wearable computers that would change the way people view others and the world.

  The glasses have a tiny video screen and a camera that connect wirelessly to the Internet through Wi-Fi,a smart phone,or a table computer. You can make and receive calls,send and receive texts,take pictures,record videos or search the Web. You control Google Glass using your voice,and a touch pad on the right arm of the frame.

Professor Marcia Dawkins is among a selected group of people who have been given a chance to test out Google Glass.

  The Professor's Google Glass looks like a bright orange glasses,without the actual glass. But there's a tiny rectangular glass at the top right-hand cor?ner. Through that glass,she has been recording videos while biking. She al?so has been able to talk to her sister inThailand, and she plans to use the de?vice to teach a public speaking class. But not everyone is excited about Google Glass. Some are concerned about possible risks to privacy. John Simpson is the director of the privacy project at Consumer Watchdog.

"It is essentially going to allow people to come in and spy on you and record that,without you knowing what is going on."

  Google says that it has already addressed that concern. Chris Dale,who is the Senior Manager of Communications for Google Glass,explained that in order to start the camera or record a video,the owner must say something out loud.

But film-maker Chris Barrett showed just how easy it is to record people without them knowing it. His glass captured a man getting arrested after a fight. He shared the video on YouTube.

  Also,some are concerned about the use of facial recognition technology on Google Glass. But Google says it will not approve the use of such applica?tions. The Internet company says it is still testing its new device,and it hopes to make Google Glass available to the public by early next year.
