     My grandfather is eighty years old. He always complains about how fast things have changed, and he

often says that life used to be better.

     "Families aren't what they used to be. A lot of families have broken up. If the husband and wife have

problems with their marriage, they no longer stay together. And mothers used to stay at home and take

care of their children, but now parents are both busy working. No one has time to look after children at

home.

     And the cars! No one walks anymore. More and more people drive. We used to walk five miles to

school on school days, even in winter. But now we don't. And in school, children don't have to think

anymore. In math class, for example, we used to add, subtract, multiply and divide by using our heads.

But now kids don't use their heads anymore. Instead, they use calculators.

     Most families have computers now. In the past we didn't have computers. We didn't even have lights.

My mother used to spend all day cooking in the kitchen. But now we don't often eat home-cooked food.

     And people talk less to each other than before. They are too busy to talk, too busy to eat, too busy to

think...Life used to be simple, but it isn't anymore."

启发性原则

This is a dangerous world we live in. The numbers of murders goes up every year； people are dying of cancer；more people contract（感染）HIV；more teens are using drugs；etc. You know this because you’ve heard all the statistics on the news. 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 dangers of the chemical known as dihydrogen monoxide. This chemical, found in most cancerous tumors（肿瘤）， is 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 32 people may die each year when skiing, while 897 die from lightning strikes, but which is really more dangerous? If you think about it, you will realize far fewer people go skiing each year than the number of people who are in danger of a lightening 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 think critically, and form our own views. rather than be easily persuaded by another’s. To be warned is to be prepared.

59．In the first paragraph, what problem does the writer want to warn us?

A. We are now living in a dangerous world.

B. We got a lot of false statistics from the media.

C. There are around us more and more murders, diseases etc.

D. Statistics alone without full background don’t give us an accurate picture of things.

60．Why does the writer use the example in the second paragraph?

B. To argue that high school students are easily persuaded.

C. To prove what is necessary to us might be dangerous.
