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 thunder—storms 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（温度）, 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.

A．People have not placed sensors one foot apart in the atmosphere.
B．Scientists have already put sensors one foot apart in the world.
C．Every sensor gives perfectly accurate data a weatherman wants.
D．Ground weather stations and satellites can see every place on earth.

Do you want to live with a strong sense of peacefulness, happiness, goodness, and self- respect? The collection of happiness actions broadly categorized(归类) as "honor" help you create this life of good feelings.
Here's an example to show how honorable actions create happiness.
Say a store clerk fails to charge
us for an item. If we keep silent, and benefit from the clerk's mistake, we would drive home with a sense of sneaky(鬼祟的) excitement. Later we might tell our family or friends about our good fortune. On the other hand, if we tell the clerk about the uncharged item, the clerk would be grateful and thank us for our honesty. We would leave the store with a quiet sense of honor that we might never share with another soul.
Then, what is it to do with our sense of happiness?
In the first case, where we don't tell the clerk, a couple of things would happen. Deep down inside we would know ourselves as a type of thief. In the process, we would lose some peace of mind and self-respect. We would also show that we cannot be trusted, since we advertise our dishonor by telling our family and friends. We damage our own reputations by telling others. In contrast, bringing the error to the clerk's attention causes different things to happen. Immediately the clerk knows us to be honorable. Upon leaving the store, we feel honorable and our self-respect is increased．Whenever we take honorable action we gain the deep internal rewards of goodness and a sense of nobility.
There is a beautiful positive cycle that is created by living a life of honorable actions. Honorable thoughts lead to honorable actions. Honorable actions lead us to a h
appier existence. And it's easy to think and act honorably again when we're happy. While the positive cycle can be difficult to start, once it's started, it's easy to continue. Keeping on doing good deeds brings us peace of mind, which is important for our happiness.
79．The author thinks that keeping silent about the uncharged item is equal to___.
A．lying
B．stealing
C．cheating
D．advertising
80．The phrase "bringing the error to the clerk's attention" （in para． 5） means___.
A．telling the truth to the clerk
B．offering advice to the clerk
C．asking the clerk to be more a
ttentive
D．reminding the clerk of the charged item
81．How will we feel if we let the clerk know her mistake?
A．We'll be very excited.
B．We'll feel unfortunate.
C．We'll have a sense of honor.
D．We'll feel sorry for the clerk.
82 .Which of the following can be the best title of this passage.
A．How to Live Truthfully
B．Importance of Peacefulness
C．Ways of Gaining Self-respect
D．Happiness through Honorable Actions
Recently I gave my adult students homework. It was “go to someone you love and tell them you love them.” It has to be someone you have never said those words to before or at least haven’t shared those words with for a long time.
It sounds like very tough homework since most of the men were over 35 and were raised in the generation of men that were taught expressing emotions is not “macho(阳刚之气).” Showing feelings or crying was just not done. So this was very threatening homework for some.
At the beginning of our next class, I asked if someone wanted to share what happened when they told someone they loved them. I fully expected one of the women to volunteer, as was usually the case, but on this evening one of the men raised his hand, quite moved and a bit shaken.
As he unfolded out of his chair (all 1.85 meters of him), he began by saying, “Dennis, I was quite angry with you last week when you gave us this homework. Why did you ask us to do something personal?”
“But as I began driving home my conscience(良心)started telling me that I knew exactly who I needed to say ‘I love you’ to.”
“Five years ago, my father and I had a severe disagreement and really n
ever settled it since then. We avoided seeing each other unless we absolutely had to at Christmas or other family gatherings. But even then, we hardly spoke to each other.”
“So last Tuesday by the time I got home I had convinced myself I was going to tell my father I loved him. It’s strange, but just making that decision seemed to li
ft a heavy load off my chest.”
75.The homework is threatening for some students because____________ .
A. they are middle-aged people B. they are not macho enough
C. they were taught to hide their emotions D. they didn’t know how to show feelings
76.From the passage we know that ________-.
A. the adult students have classes in the day time only
B. not all the adult students in the writer’s class are male
C. the man refused to meet his father after their quarrel
D. the man quickly decided to say “I love you” to his father
77.The underlined phrase “unfolded out of his chair” in Para 4 is closest in meaning to_______.
A. stood on his chair straight B. sat quietly in the chair
C. bent himself over his chair D. raised himself slowly from the chair
78.What does the man imply by saying the underlined sentence in the last paragraph?
A. He felt it too strange to say “I love you” to his father.
B. He felt relaxed just thinking of saying “I love you” to his father.
C. He felt very relaxed after saying “I love you” to his father.
D. He had to lift a 
heavy load off his chest before saying “I love you”.

Now when the old woman could see again she noticed that all her things had gone and she refused to pay the bill. So the doctor took her before a judge.
“What the doctor says is true.” she said to the judge. “But I say I’m not cured, because I still can’t see any of the things in my house.”

There are two kinds of physical activity which require special training. The first demands exact careful movements of the muscles（肌肉）. This kind of activity must be strictly controlled because even a slight movement in the wrong direction will lead a mistake. To type quickly, for example, a person needs training; the slightest movement of a finger in the wrong direction may cause a spelling mistake. A dancer who has to dance on the point of her shoes or turn around on one foot must be trained for a long period of time before she can sense her own center and balance herself. You may have seen a girl walking on a rope across an empty space, which, too, requires a lot of practice.
The second kind of physical activity needs greater strength or extra effort. Most of us get tired if we try to run half a mile without stopping, but a specially-trained person can do this without much effort. Three years ago, some scientists carried out experiments, which produced meaningful and unexpected results. They wanted to find out whether a certain amount of physical exercise would injure those suffering from heart problems. They selected some male patients and trained them in continuous bicycle riding. They were surprised to find that the harmful effect of given amount of physical effort was actually less on the hearts of these trained patients than on those of the patients who were not similarly trained. This is important because it shows that regular physical exercise enables us to make better use of the oxygen（氧气）we breathe in and that this training, in fact, reduces the amount of work our hearts do. Many tasks which are hard for untrained people are not hard at all for trained people.
72．The first kind of physical activity must be strictly controlled because _________.
A．a mistake in the wrong direction is dangerous to the fingers
B．a wrong movement in a direction will cause no mistakes
C．a movement in the wrong direction will cause a mistake
D．a slight movement of a finger will lead to a mistake
73．What must a dancer do before she can balance herself?
A．She must dance on the point of her shoes. B．She must receive long-time training.
C．She must turn around on one foot. D．She must perform again and again.
74．The experiments done by some scientists showed that ________.
A．some male patients were asked to ride bicycles regularly in the experiments
B．the physical exercise had more harmful effect on the hearts of the untrained patients
C．the physical exercise was harmless to the male patients with heart trouble
D．the physical exercise could be helpful for the patients to take in more oxygen
75．What would be the best title for this text?
A．Training Our Bodies B．Physical Activities
C．Movement Training D．Extra Body Effort
Language as a System of Symbols
Of all systems of symbols(符号）, language is the most highly developed. It has been pointed out that human beings, by agreement, can make anything stand for anything. Human beings have agreed, in the course of centuries of mutual(相互的）dependency, to let the various noises that they can produce with their lungs, throats, tongues, teeth, and lips systematically stand for certain happenings in their nervous systems. We call that system of agreements language.
There is no necessary connection between the symbol and that which it stands for. Just as social positions can be symbolized by feathers worn on the head, by gold on the watch chain, or by a thousand other things according to the culture we live in, so the fact of being hungry can be symbolized by a thousand different noises according to the culture we live in.
However obvious these facts may appear at first glance, they are actually not so obvious as they seem except when we take special pains to think about the subject. Symbols and the things they stand for are independent of each other, yet we all have a way of feeling as if, and sometimes acting as if, there were necessary connections. For example, there are people who feel that foreign languages are unreasonable by nature; foreigners have such funny names for things, and why can’t they call things by their right names? This feeling exhibits itself most strongly in those English and American tourists who seem to believe that they can make the natives of any country understand English if they shout loud enough. Like the little boy who is reported to have said: “Pigs are called pigs because they are such dirty animals,” they feel that the symbol is inherently(内在地） connected in some way with the things symbolized.
68．Language is a highly developed system of symbols because human beings ______.
A．have made use of language for centuries
B．use our nervous systems to support language
C．have made various noises stand for any events
D．can make anything stand for anything by agreement
69．What can we conclude from Paragraph 2?
A．Different noises may mean different things.
B．Our culture determines what a symbol stands for.
C．The language we use symbolizes our social positions.
D．Our social positions determine the way we are dressed.
70．In Paragraph 3, “take special pains” probably means “_____”.
A．try very hard B．take our time C．are very unhappy D．feel especially painful
71．The example of the little boy is used to show that _____.
A．adults often learn from their young
B．“pig” is a dirty word because pigs are dirty
C．words are not connected with the things they stand for
D．people sometimes have wrong ideas about how language works
