　　Let children learn to judge their own work．A child learning to talk does not learn by being corrected all the time：if corrected too much, he will stop talking．He notices a thousand times a day the difference between the language he uses and the language those around him use．Bit by bit, he makes the necessary changes to make his language like other people’s．In the same way, children learning to do all the other things：they learn to do without being taught to walk, run, climb, whistle, ride a bicycle, compare their own performances with those of more skilled people, and slowly make the needed changes．But in school we never give a child a chance to find out his mistakes and correct them for himself．We do it all for him．We act as if we thought that he would never notice a mistake unless it was pointed out to him, or correct it unless he was made to．Let him work out, with the help of other children if he wants it, what this word says, what the answer is to that problem, whether this is a good way of saying or doing this or not．

　　If it is a matter of right answer, as it may be in mathematics or science, give him the answer book．Let him correct his own papers．Why should we teachers waste time on such routine(常规)work?Our job should be to help the child when he tells us that he can’t find the way to get the right answer．Let the children learn what all educated persons must some day learn, how to measure their own understanding, and how to know what they know or do not know．

　　Laptop computers are popular all over the world．People use them on trains and airplanes, in airports and hotels．These laptops connect people to their workplace．In the United States today, laptops also connect students to their classrooms．

　　Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork anywhere they want．Within five years, each of the 1500 students at the college will receive a laptop．The laptops are part of a ＄10 million computer program at Westlake, a 110-year-old college．The students with laptops will also have access to the Internet．In addition, they will be able to use e-mail to“speak”with their teachers, their classmates, and their families．However, the most important part of the laptop program is that students will be able to use computers without going to computer labs．They can work with it at home, in a fast-food restaurant or under the trees-anywhere at all!

　　Because of the many changes in computer technology, laptop use in higher education, such as colleges and universities, is workable．As laptops become more powerful, they become more similar to desktop computers．In addition, the portable computers can connect students to not only the Internet, but also libraries and other resources．State higher-education officials are studying? how laptops can help students．State officials are also testing laptop programs at other universities, too．

　　At Westlake College, more than 60 percent of the staff use computers．The laptops will allow all teachers to use computers in their lessons．As one Westlake teacher said,“Here we are in the middle of Virginia and we’re giving students a window on the world．They can see everything and do everything．”

　　Trees are useful to man in three important ways：they give him wood and other useful things, they give him cool places, and they help to stop drought and flood．

　　Unluckily, in many parts of the world, man has not found that the third of these points is the most important．Man wants to make money from trees,so he has cut them down in large numbers, only to find that without them he has lost the best friends he had．And also, he is usually too careless to plant and look after new trees．So the forests slowly disappear．

　　This does not only mean that man will have fewer trees．The results are even worse：for where there are trees, their roots break up soil-make the rain in-and also bind the soil, thus stopping it from being washed away easily; but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying away the rich top-soil．When all the top-soil is gone, nothing is left but useless desert．

　　When we can see well, we do not think about our eyes often．It is only when we can not see perfectly that we come to see how important our eyes are．

　　People who are nearsighted can only see things that are very close to their eyes．Many people who do a lot of close work, such as writing and reading, become nearsighted．Then they have to wear glasses in order to see distant things clearly．

　　People who are farsighted face just the opposite problem．They can see things that are far away, but they have difficulty reading a book unless they hold it at arm’s length．If they want to do much reading, they must get glasses too．

　　Other people do not see clearly because their eyes are not exactly the right shape．This, too, can be corrected by glasses．Some people’s eyes become cloudy because of cataracts．Long ago these people often became blind．Now, however, it is possible to operate on the cataracts and remove them．

　　When night falls, colors become fainter to the eyes and finally disappear．After your eyes have grown used to the dark, you can see better if you use the side of your eyes rather than the centers．Sometimes, after dark, you see a small thing to one side of you, which seems to disappear if you turn your head in its direction．This is because when you turn your head, you are looking? at the thing too directly．Men on guard duty sometimes think they see something moving to one side of them．When they turn to look straight at it, they can not see it any more, and they believe they were mistaken．However, this mistake happens because the center of the eye, which is very sensitive in daylight, is not as sensitive as the sides of the eye after dark．

　　When Geoff Marcy was 14, his parents bought him a telescope．Every night, he would go onto the roof outside his window to see the wonders of the sky．

　　“What excited me most was whether there were planets in other solar systems where life might exist,”he says．“I decided to try to find planets orbiting(沿…轨道运行)other stars like our Sun．”

　　And he did．“My fellow researcher, Paul Butler, and I found our first planet in 1995,”Dr．Marcy says．“We worked for ten years without finding anything!But we stuck with it, and our patience paid off．”

　　Since then, the two scientists have discovered 65 of the more than 100 planets orbiting other stars．Dr．Marcy and Dr．Butler also spotted the first“family”of three planets．In June 2002 they announced another discovery：a Jupiter-like(像木星一样的)planet orbiting star 55 Cancri．

　　At first, the two researchers found only planets that orbit close to stars．Recently, the scientists found planets farther out．The planet orbiting 55 Cancri is a major breakthrough：it is the first sighting of a large gas planet about the same distance from the star as Jupiter is from the Sun．

　　Why is this important?Scientists think that life on Earth may exist because of two special features in our solar system．The first is Jupiter．

　　“Because it’s so big, Jupiter pulls comets and asteroids(小行星), or they all come and hit the Earth．”Dr．Marcy explains．“Without Jupiter, life on Earth would likely have been destroyed．”

　　A second feature is that Earth is a rocky planet where liquid water, which is necessary for life, can exist．Unlike gas planets, rocky planets like Earth have surfaces where water can gather in pools and seas, which may support life．A huge space exists between the Jupiter-like planet and two other planets that lie close to 55 Cancri．Is there an Earthlike planet in the space, too small for us to notice?If so, says Dr．Marcy,“We would have two striking similarities to our solar system：a Jupiter-like planet and an Earth-like planet．And there may be life!”

　　When a consumer(消费者)finds that something he or she bought is faulty or in some other way does not live up to what the producer says for it, the first step is to present the warranty(保单), or any other records that might help, at the store of buying．In most cases, this action will produce results．However, if it does not, there are various means the consumer may use to gain satisfaction．

　　A simple and common method used by many consumers is to complain(投诉)directly to the store manager．In general, the“higher up”the consumer takes his or her complaint, the faster he or she can expect it to be settled．In such a case, it is usually settled in the consumer’s favour, taking it as true that he or she has a just right．

　　Consumers should complain in person whenever possible, but if they cannot get to the place of buying, it is acceptable to phone or write the complaint in a letter．

　　Complaining is usually most effective when it is done politely but firmly, and especially when the consumer can show clearly what is wrong with what was bought in question．If this cannot be done, the consumer will succeed best by presenting specific information as to what is wrong, rather than by making general statements．For example,“The left speaker does not work at all and the sound coming out of the right one is unclear”is better than“This stereo(立体音响)does not work”．

　　The store manager may advise the consumer to write to the producer, if so, the consumer should do this, stating the complaint as politely and as firmly as possible．But if a polite complaint does not achieve the expected result, the consumer can go a step further．He or she can threaten(恐吓)to take the seller to court or report the seller to a public organization responsible for protecting consumers’ rights．
