Passage 20

(上海市崇明中学2009届高三5月高考模拟考试C篇)

Beyond two or three days, the world’s best weather forecasts are doubtful, and beyond six or seven they are worthless.

The Butterfly Effect is the reason. For small pieces of weather-to a global forecaster, small can mean thunderstorms and blizzards (暴风雪)-any prediction becomes worse rapidly. Errors and uncertainties increase, from dust devils and storms up to continent-size eddies (旋涡) that only satellites can see.

The modern weather models work with net-like points sixty miles apart, and even so, some starting data have to be guessed, since ground stations and satellites cannot see everywhere. But suppose the earth could be covered with sensors placed one foot apart, rising at one-foot intervals all the way to the top of the atmosphere. Suppose every sensor gives perfectly accurate readings of temperature, pressure, humidity (湿度), and any other data a weatherman would want. Exactly at noon a powerful computer takes all the data and calculates what will happen at each point at 12.01, then 12.02, then 12.03… the computer will still be unable to predict whether Princeton will have sun or rain one month away. At noon the spaces between the sensors will hide fluctuations (波动) that the computer will not know about. By 12.01, those fluctuations will already have created small errors one foot away. Soon the errors will have added to the ten-foot scale, and so on up to the size of the globe.

Passage 19

(陕西省师大附中2009届高三第四次模拟考试A篇)

Doctors say anger can be an extremely damaging emotion, unless you learn how to deal with it. They warn that anger can lead to heart disease, stomach problems, headaches, emotional problems and possibly cancer.

Anger is a normal emotion that we all feel from time to time. Some people express anger openly in a calm reasonable way. Others burst with anger, and scream and yell. But other people keep their anger inside. They can not or will not express it. This is called repressing anger.

For years many doctors thought that repressing anger was more dangerous to a person's health than expressing it. They said that when a person is angry, the brain releases the same hormones (荷尔蒙).They speed the heart rate, raise blood pressure, or sugar into the blood, etc．In general the person feels excited and ready to act.

Some doctors say that both repressing and expressing anger can be dangerous. They believe that those who express anger violently may be more likely to develop heart disease, and they believe that those who keep their anger inside may face a greater danger of high blood pressure.

Doctors say the solution is learning how to deal with anger. They say the first step is to admit that you are angry and to recognize the real cause of the anger, then decide if the cause is serious enough to get angry about. If it is, they say, “Do not express your anger while angry. Wait until your anger has cooled down and you are able to express yourself calmly and reasonably.”

Doctors say that a good way to deal with anger is to find humor in the situation that has made you angry. They said that laughter is much healthier than anger.
