　　In the atmosphere, carbon dioxide allows the sun’s rays to enter but prevents the heat from escaping．According to a weather expert’s prediction, the atmosphere will be 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．

　　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 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 part of the earth, where temperatures seem to be falling．Scientists conclude, therefore, that up to now natural influences on the weather have exceeded those caused by man．The question is：Which natural cause has most effect on the weather?

　　One possibility is the 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．This seems to have a greater effect on the distribution of the earth’s atmospheric pressure, and consequently on wind circulation(循环)．The sun is also variable(可变的)over a long term．Its heat output(输出)goes up and down in cycles．The latest trend being downward is on the way．But that is only a imagination．

[　　]

partly due to the activity of the sun

My house is made out of wood, glass and stone. It is also made out of software.

If you come to visit, you’ll probably be surprised when you come in. Someone will give you an electronic PIN （个人身份号码）to wear. This PIN tells the house who and where you are. The house uses this information to give you what you need. When it’s dark outside, the PIN turns on the lights nearest you, and then turns them off as you walk away from them. Music moves with you too. If the house knows your favorite music, it plays it. The music seems to be everywhere, but in fact other people in the house hear different music or no music. If you get a telephone call, only the nearest telephone rings.

Of course, you are also able to tell the house if you want something. There is a home control console (控制台), a small machine that turns things on and off around you.

The PIN and the console are new ideas, but they are in fact like many things we have today. If you want to go to a movie, you need a ticket. If I give you my car keys, you can use my car. The car works for you because you have the keys. My house works for you because you wear the PIN or hold the console.

I believe that ten years from now, most new homes will have the systems that I’ve put in my house. The systems will probably be even bigger and better than the ones I’ve put in today.

I like to try new ideas. I know that some of my ideas will work better than others. But I hope that one day I will stop thinking of these systems as new, and ask myself instead, “How will I live without them?”

What does the passage mainly discuss?

A. How to develop a new system.            B. The function of the PIN.

C. A home for the future.                  D. Easy life in the future.

What’s the purpose when the writer wrote the fourth paragraph?

A. To let readers know why his ideas are new.

B. To let readers know how special his house is.

C. To explain the importance of the PIN and the console.

D. To explain more easily what the functions of the PIN and the console are.

The writer’s new house is different from ordinary ones mainly because _____.

A. it has been controlled by computers

B. you can make a telephone call anywhere

C. it has your favorite music following you

D. the writer is able to change his new idea into practice

What is the writer most likely to be according to the passage?

A. An IT expert.    B. A famous doctor. 

C. An idealist      D. An experienced teacher.

What can’t be done in the writer’s new house?

A. turns on the lights

B. play music

C. get a telephone call

D. go swimming

It has been argued that an infant under three who is cared for outside the home may suffer because of the separation from his parents．The British psychoanalyst John Bowlby believes that separation from the parents during the sensitive "attachment" period from birth to three may scar （留下疤痕） a child's personality and incline to emotional problems in later life．Some people have drawn the conclusion from Bowlby's work that children should not be sent to day care before the age of three, and many people do believe this．But there are also arguments against such a strong conclusion．

Firstly, anthropologists （人类学家） point out that the hidden love between children and parents found in modem societies does not usually exist in traditional societies．For example, we saw earlier that among the Ngonis the father and mother of a child did not raise their infant alone．But traditional societies are so different from modern societies that comparisons based on just one factor are hard to understand．

Secondly, common sense tells us that day care would not be so widespread today if parents and caretakers found that children had problems with it．But Bowlby's analysis raises the possibility that early day care has delayed effects．The possibility that such care might lead to more mental illness or crime 15 or 20 years later can only be noticed by the use of statistics．Statistical studies of this kind have not yet been carried out, and even if they were, the results would be certain to be complicated and controversial．

Thirdly, in the last decade, there have been a number of careful American studies of children in day care, and they have reported that day care had a neutral of slightly positive effect on children's development．But tests that have had to be used to measure this development are not widely enough accepted to settle the issue．

    A．should not be sent to school
