In the atmosphere， carbon dioxide acts rather like a one-way mirror 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 wilbe3C warmer in the year 2050thanitis today， if man continues to burn fuels at the present rate.If this warming up took place， the icecaps 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(半球) ， 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 maybe 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 exceeded 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(旋转) ， 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 variable over along term：its heat output goes up and down in cycles， the latest trend being downward.
Scientists are now finding mutual relations between models of solar-weather interactions 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(惯性) of the earth's climate.If this is right，the warming effect of carbon dioxide might thus be serving as a useful counter-balance to the sun's diminishing(减少) heat.

One recent night， while I was leafing through its pages of an old journal， my eyes met a quote by the British writer Graham Greene that I had marked， “A prejudice had something in common with an ideal.”In other words， ideals—general descriptions of people's expectations of themselves and others—can often lead us to unreasonable ideas.It got me thinking about how we often allow ourselves to generalize about groups of people.We like to stereotype people by the color of their skin， the year of their birth or any other related factors.
I grew up in a multi-racial corner of America.The different groups were often subject to narrow stereotypes：Jewish people were“greedy”， Mexicans were“poorly educated”， and Asians were“good at math”.These labels were taught to us from a young age.They wormed their way into our belief systems， harming how we came to see others.It made me sad growing up to see people repeat these stereotypes as if they were true.The rush-to judgment of people breeds a culture of discrimination.
You can also see these over-generalized descriptions being made against today's Chinese people.Whether it be a lack of interest or worry among mile millennial being described as “monkish”， or“dad-fashion”which has given the“greasy middle-aged men”tag.stereotypes always seem to gain a foothold in the consciousness of our society.But these generalizations do real harm as these myths may become part of the wider population.
It's about time that we， as a society， walked away from generalizations and stereotypes.I leave you with the words of Martin Luther King Jr.from his famous“I Have a Dream”speech：“T look to a day when people will not be judged by the color of their skin， but by the content of their character.”By reserving judgment and really getting to know the individual you might just find your irrational ideas have no foundation.
1.According to the passage， how do people tend to judge others?
A.By describing people's personalities.
B.By truly getting to know those around.
C.By observing their noticeable features.
D.By following Martin Luther King's speech.
2.Examples of“millennial”and dad-fashion”are mentioned in Paragraph 3 to reveal .
A.generalizations have unfavorable position in society
B.generalizations have a negative influence on our society
C.generalizations are found peculiar to the middle-age Chinese
D.generalizations make today's Chinese people lack interest or worry
3.The passage is mainly concerned with .
A.the common prejudice
B.people's expectation of themselves
C.the groundless worries
D.the famous speech of Martin Luther King Jr.
People, old or young, can enjoy many different performances at theaters or concert halls, which have become an important part of our culture.
“LOUDMOUTH”at the Tank(through Nov.18) .Young theatergoers may not be familiar with the expression,but the title of the show is a great example：Its10-yearoldheroine, Amy,dislike stalking.The theatre piece explore show Amy finally finds her voice through an imaginative games he plays with her friends.The production also offers an optional performance workshop where participants invent their own games.
