Of all the areas of learning the most important is the development of attitudes. Emotional reactions as well as logical thought processes affect the behavior of most people.
“The burnt child fears the fire” is one instance; another is the rise of figures like Hitler. Both these examples point up the fact that attitudes come from experience. In the one case the experience was direct and impressive; in the other it was indirect and gradual.
The classroom teacher in the elementary school is in strategic position to influence attitudes. This is true partly because children acquire attitudes from those adults whose word they respect.
Another reason it is true is that pupils often search somewhat deeply into a subject in school that has only been touched upon at home or has possibly never occurred to them before. To a child who has previously acquire little knowledge of Mexico, his teacher’s method of handling such a unit would greatly affect his attitude toward Mexicans.
The teacher can develop proper attitudes through social studies, science matters, the very atmosphere of the classroom, etc. However, when children come to school with undesirable attitudes, it is unwise to attempt to change their feelings by criticizing them. The teacher can achieve the proper effect by helping them obtain constructive experience.
To illustrate, first-grade pupils, afraid of policemen will probably change their attitudes after a classroom talk with the neighborhood officer in which he explains how he protects them. In the same way, a class of older children can develop attitudes through discussion, research, outside reading and all-day trips.
Finally, a teacher must constantly evaluate her own attitudes, because her influence can be harmful she has personal prejudices. This is especially true in respect to controversial issues and questions of which children should be encouraged to reach their own decisions as result of objective analysis of all the facts.

In the atmosphere．carbon dioxide．acts rather like a one-way mirror or the glass in the roof of a greenhouse which allows the sun’s rays to enter but prevents the heat from escaping．
According to a weather expert’s prediction，the atmosphere will be 3°C warmer in the year 2050 than it is today, if man continues to burn fuels at the present rate．If this warming up took place，the ice caps in the poles would begin to melt, thus raising sea level several meters and severely flooding coastal cities．
Also，the increase in atmospheric temperature would lead to great changes in the climate of the northern hemisphere，possibly resulting in an alteration of the earth’s chief food growing zones．
In the past，concern about a man-made warming of the earth has concentrated on the Arctic because the Antarctic is much colder and has a much thicker ice sheet．But the weather experts are now paying more attention to West Antarctic，which may be affected by only a few degrees of warming，in other words，by a warming on the scale that will possibly take place in the next fifty  years from the burning of fuels．
Satellite pictures show that large areas of Antarctic ice are already disappearing．The evidence available suggests that a warming has taken place．This fits the theory that carbon dioxide warms the earth．
However, most of the fuel is burnt in the northern hemisphere，where temperatures seem to be falling．Scientists conclude，therefore，that up to now natural influences on the weather have gone beyond those caused by man．The question is：Which natural cause has most effect on the weather?  
One possibility is the variable behavior of the sun．Astronomers at one research station have studied the hot spots and ‘cold’ spots (that is，the relatively less hot spots)on the sun．As the sun rotates，every 27．5 days，it presents hotter or colder faces to the earth，and different aspects to different parts of the earth．This seems to have a considerable effect on the distribution of the earth’s atmospheric pressure，and consequently on wind circulation．The sun is also changeable over a long term：its heat output goes up and down in cycles，the latest trend being downward．
Scientists are now finding shared relation between models of solar weather interaction and the actual climate over many thousands of years，including the last Ice Age．The problem is that
the models are predicting that the world should be entering a new Ice Age and it is not．One way of solving this theoretical difficulty is to assume a delay of thousands of years while the solar effects overcome the inertia(惰性)of the earth’s climate．If this is right，the warming effect of carbon dioxide might thus be serving as a useful opposed balance to the sun’s fading heat．
72．It can be concluded that a concentration of carbon dioxide in the atmosphere would ______．
A．mean a warming-up in the Arctic
B．raise the temperature of the earth’s surface
C．prevent the sun’s rays from reaching the earth’s surface
D．explain the cause of great changes in the climate in the northern hemisphere
73．Although the fuel consumption is greater in the northern hemisphere, temperatures there
seem to be falling．This is _______．
A．mainly because the levels of carbon dioxide are rising
B．partly due to changes in the output of solar energy
C．possibly because the ice caps in the poles are melting  
D．only due to the effect of the inertia of the earth’s climate
74．On the basis of their models , scientists are of the opinion that  ________
A．the climate of the world should be becoming cooler
B．the new Ice Age will be delayed by the greenhouse effect
C．the man．made warming effect helps to increase the solar effects  
D．it will take thousands of years for the inertia of the earth’s climate to take effect
75．If the assumption about the delay of a new Ice Age is correct ,  _________     
A．ice would soon cover the northern hemisphere
B．the greenhouse effect could work in favor of the earth
C．the best way to overcome the cooling effect would be to bum more fuels
D．the increased levels of carbon dioxide could warm up the earth even more quickly

Wearing ties was originally the mark of Britain’s most powerful classes, which made the tie itself a symbol of power and respect. And that led it to be adopted by a much larger tribe－the business tribe.
You cannot wear a tie if you work with machinery. So wearing a tie became a sign that you were a man who used your brain to make a living, rather than your hands. It showed you were serious. It showed you were a professional. It meant that everyone who wanted a job in business had to wear one. It was just impossible to take seriously a man who didn’t wear a piece of colored silk around his neck.
This is how millions of people came to be wearing ties across the world. They are part of the uniform of business.
“Ties offer a point of indifference,” says John Milne, head of the British Guide of Tie Makers, “They give a chance to say something about their own personality.”
So if you happen to meet a man with a very brightly colored tie, there is a good chance that he is the office joker. There is also a good chance that he will be wearing brightly colored socks.
Is there a future for ties? The signs are not promising. Tie wearing seems to be rare among the new bread of entrepreneurs(创业者) in the Internet and new technology industries. Many political leaders, including former British Prime Minister Tony Blair, now go without ties. This shows they are men of the people－but not the people wearing ties.
Up until around 1960, it was common for men across the western world to wear hats as part of their business uniform. That changed with the election of John F. Kennedy to the presidency of the United States. Kennedy never wore a hat－in fact his nickname was “hatless Jack”. Seeing that the most powerful man in the world did not have to wear a hat, millions of other men decided that they did not have to, either. Hats simply vanished across the Western world. Perhaps “tieless Tony” (former UK Prime Minister Tony Blair) will have the same effect as “hatless Jack”.
66．In Britain, ties were first used as a sign to show a person’s __________.
A．personality       B．social position  C．wearing style    D．favorite hobby
67．In the business world, wearing a tie was necessary because _________.
A．it showed you used your brain       B．it showed you got a good salary
C．it showed you were an employer    D．it showed you were well-equipped
68．The underlined word “vanished” in this passage may mean _________.
A．sold  B．washed     C．appeared   D．disappeared
69．The writer may hold the opinion that _____________.
A．Blair is the best leader in the world
B．Kennedy is the best leader in the world
C．millions of people will go to work without a tie
D．people will wear hats instead of ties
70．Which of the following statements is TURE according to the passage?
A．If you are a professional, you can’t wear a tie in Britain
B．The tie will become more fashionable and popular in the future
C．It was the election of John F．Kennedy to the presidency of the United States that changed the fact that wearing hats as part of their business uniform
D．Men across the western world didn’t wear hats as part of their business uniform until around 1960

Parents should stop blaming themselves because there’s not a lot they can do about it. I mean the teenager problem. Whatever you do or however you choose to deal with it, at certain times a wonderful, reasonable and helpful child will turn into a terrible animal.
I’ve seen friends deal with it in all kinds of different ways. One strict mother insisted that her son, right from a child, should stand up whenever anyone entered the room, open doors and shake hands like a gentleman. I saw him last week when I called round. Sprawling himself (懒散地躺) on the sofa in full length, he made no attempt to turn off the loud TV he was watching as I walked in, and his greeting was no more than a quick glance at me. His mother was ashamed. “I don't know what to do with him these days,” she said. “He’s forgotten all the manners we taught him.”
He hasn’t forgotten them. He’s just decided that he’s not going to use them. She confessed (坦白) that she would like to come up behind him and throw him down from the sofa onto the floor.
Another good friend of mine let her two daughters climb all over the furniture, reach across the table, stare at me and say, “I don’t like your dress; it’s ugly.” One of the daughters has recently been driven out of school. The other has left home.
“Where did we go wrong?” her parents are now very sad. Probably nowhere much. At least, no more than the rest of that unfortunate race, parents.

When a rather dirty, poorly dressed person kneels at your feet and puts out his hands to beg for a few coins, do you hurry on, not knowing what to do, or do you feel sad and hurriedly hand over some money? What should our attitude to beggars be? There can be no question that the world is full of terribly sad stories. It must be terrible to have no idea where our next meal is going to come from. It seems cruel not to give some money to beggars.
Certainly, most of the world’s great religions (宗教) order us to be open-hearted and share what we have with those less fortunate than ourselves. But has the world changed? Maybe what was morally (道德方面) right in the old days, when one knew exactly who in the village had suffered misfortune and needed help, is no longer the best idea. Quite a few people will not give to beggars. Let us look at their arguments.
First, some believe that many city beggars dress up on purpose to look pitiable and actually make a good living from begging. Giving to beggars only encourages this sort of evil (恶行). Secondly, there is the worry that the money you give will be spent on beer, wine or drugs. Thirdly, there is the opinion that there is no real excuse for begging. One might be poor, but that is no reason for losing one’s sense of pride and self-dependence.
Related to this is the opinion that the problem should be dealt with by the government rather than ordinary people. Some people think beggars should go to the local government department and receive help.
It is hard to come to any final conclusion; there are various cases and we must deal with them differently. A few coins can save a life in some situations, and even if the money is wasted, that does not take away the moral goodness of the giver.
59. What is mainly discussed in the passage?
A. Moral deeds of people.         B. Religious activities of the church.
C. Moral goodness of the giver.     D. Arguments on giving to beggars.
60. What can we infer from the sentence “But has the world changed?” in the second paragraph?
A. People no longer know who suffers misfortune in the village.
B. Some people will not do what was morally right in the past .
C. We don’t meet with those who need help any more.
D. Now it is the government’s duty to help the beggars.
61. Which of the following is NOT mentioned in the passage?
A. Some people dress up to pretend to be beggars.
B. Some beggars want money to help their children go to school.
C. Some beggars use the money to buy drugs.
D. Some beggars have no excuse for begging.
62. In the last paragraph, the writer thinks that it is hard to come to any final conclusion, because______.
A. the cases can be so different
B. there are so many beggars
C. there is so much money wasted
D. there are so many different arguments
