题目内容
17.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,etc.You know this because you have 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 growing 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(肿瘤),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 statements is true,yet this chemical is necessary to all life on earth.The students made the 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 out information that is different to his view.For example,look again at the statistics that suggest skiing is safe.Only 32people may die each year when skiing,while 897die from lightning strikes,but which is really the most dangerous?If you think about it,you realize far fewer people go skiing each year than the number of people who are in danger of a lightning strike.When you think about it,skiing is more dangerous than you might at first think when looking at 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 to be prepared.

分析 本文论述了片面报道的危害性,例如有些片面数据表明谋杀案的数量在增加,这项数据引起人们的极大恐慌;一个学生发现一氧化二氢的危害,使得对一氧化二氢禁用,而实际这些数据都是片面的,但是这些报道却忽视了这一点,从而造成不必要的恐慌.所以人们在在对事物只有一知半解的时候不能发表不负责任的言论,同时要学会批判性的来看待别人的观点.
