题目内容
This is a dangerous world we live in. The number of murders goes up every year, people are dying of cancer, more people contract HIV, more teens are using drugs, ect. You know this because you’ve heard all the statistics on the news and in the paper. But do you really have an accurate idea what they mean? The numbers are going up, but how do they compare to the growth in population? Are more cases of these diseases being reported because of better testing techniques, or are the diseases more common? The fact is that without knowing the background statistics mean very little.
This growing trend of reporting only part of the information is becoming dangerous. For example, several years ago a high school student reported the dangers of the chemical known as dihydrogen monoxide. This chemical, found in most cancerous tumors, is often found in the blood of people drunk on alcohol, and causes complete physical and mental dependence for those who take the chemical even once. After reading his report, more than 75% of his Advanced Placement Chemistry class voted to forbid this dangerous chemical! Every one of the above statement is true, yet this chemical is necessary to all life on earth. The students made a mistake because they voted knowing only a few statements and statistics, rather than the chemical’s full background.
The point of this article is that one should be aware of what is and is not being said. When one finds a new fact or number, one should try to consider other important information before forming an opinion with only half-truths. Always remember that the author is trying to convince you of his or her own view, and will leave our information that is different from his view. For example, look again at the statistics that suggest skiing is safe. Only 32 people die each year when skiing, while 897 die from lightening strikes, but which is really more dangerous? If you think more about it, you will realize far fewer people go skiing each year than the number of people in danger of a lightning strike. When you think about it again, skiing is more dangerous than you might at first think when looking at the statistics. If we teenagers are to be left in this world, we had better be able to think critically, and form our own views, rather than be easily persuaded by another’s. to be warned is just to be prepared.

Let children learn to judge their own. A child who learns 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. Little by little, he makes the necessary changes to make his language like other people’s, in the same way, children learn to do all the other things without being taught—to walk, run, climb, 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 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 answers, 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 in doing such work? Our job should be to help the child when he tells us that he can’t find the way to get their own understanding, how to know what they know or do not know.
