　Stonehenge（巨石阵）may have been a prehistoric health center rather than a site for observing stars or a temple in honor of the dead, scientists said yesterday. New evidence unearthed at the World Heritage Site in more than 40 years suggests that the monument was a place where the diseased and injured went in groups, seeking cures.
After a two-week dig, scientists have concluded that Stonehenge was “the ancient healthcare centre of southern England” because of the existence of “bluestones”---the smaller columns of dolerite（辉绿岩）that formed an earlier stone structure.
By dating pieces of remains to around 7330BC, Tim Darvill, of Bournemouth University, and Goff Wainwright, of the Society of Amtiquaries have found that hunter-gatherers were at the site on Salisbury Plain 4,000 years earlier than thought. The first stage of Stonehenge, a round earthwork structure, was built around 3000BC. Professor Wainwright added: “I did not expect the degree of complexity we discovered. We’re able to say so much more about when Stonehenge was built and why---all of which changes our previous understanding of the monument.”
The research reveals the importance of the henge’s famous bluestones. Hundreds of bluestone chips gathered at the site have led the team to conclude that the bluestones were valued for their curing effects---the key reason that about 80 of them, each weighing up to 4 tons and a half, were dragged more than 150 miles from the Preseli Hills to Wiltshire. After years of research, Professors Darvill and Wainwright have concluded that, for thousands of years, the Preseli mountain range was home to magical health centers and holy wells.
Even today there are those who believe in the curing powers of the springs for coughs and heart disease, and people who use crystals and bluestones for self-curing. Radiocarbon tests have also revealed that the construction of the original bluestone circle took place around 2300BC, three centuries later than originally thought. Interestingly, on the same day died the “Amesbury Archer”---a sick traveler from the Swiss or German Alps who had an infected knee---whose remains were discovered about five miles from Stonehenge. The professors believe that he was a devoted religious person who was hoping to benefit from the curing powers of the monument.

James Cleveland Owens was the son of a farmer and the grandson of black slaves. His family moved to Cleveland when he was 9.There,  a school teacher asked the youth his name.

"J.C., "he replied.

She thought he had said "Jesse", and he had a new name.

Owens ran his first race at age 13.After high school, he went to Ohio State University.He had to work part time so as to pay for his education.As a second?  year student,  in the Big Ten games in 1935, he set even more records than he would in the Olympic Games a year later.

A week before the Big Ten meet,  Owens accidentally fell down a flight of stairs. His back hurt so much that he could not exercise all week,  and he had to be helped in and out of the car that drove him to the meet. He refused to listen to the suggestions that he give up and said he would try,  event by event. He did try,  and the results are in the record book.

The stage was set for Owens? victory at the Olympic Games  in Berlin the next year,  and his success would come to be regarded as not only athletic but also political.Hitler did not congratulate any of the African?American winners.

"It was all right with me, "he said years later."I didn?t go to Berlin to shake hands with him, anyway."

Having returned from Berlin,  he received no telephone calls from the president of his own country,  either.In fact, he was not honored by the United States until 1976, four years before his death.

Owens? Olympic victories  made little difference to him. He earned his living by looking after a school playground, and accepted money to race against cars, trucks,  motorcycles and dogs.

"Sure, it bothered me, "he said later."But at least it was an honest living. I had to eat."

In time,  however,  his gold medals changed his life."They have kept me alive over the years, "he once said."Time has stood still for me.That golden moment dies hard."

Owens got his other name "Jesse" when.

A.　he went to Ohio State University    

B.　his teacher made fun of him

C.　his teacher took "J. C."for "Jesse"

D.　he won gold medals in the Big Ten meet

　In the Big Ten meet，Owens.

A.　hurt himself in the back                B.　succeeded in setting many records

C.　tried every sports event but failed   D.　had to give up some events

　We can infer from the text that Owens was treated unfairly in the US at that time because.

A.　he was not of the right race

B.　he was the son of a poor farmer

C.　he didnˊt shake hands with Hitler

D.　he didnˊt  talk to the US president on the phone

When Owens says "They have kept me alive over the years ",he means that the medals.

A.　have been changed for money to help him live on

B.　have made him famous in the US

C.　have encouraged him to overcome difficulties in life

D.　have kept him busy with all kinds of jobs

What would be the best title for the text?

A.　Jesse Owens,  A Great American Athlete

B.　Golden Moment — A Life?time Struggle

C.　Making A Living As A Sportsman

D.　How To Be A Successful Athlete

　　In the atmosphere,carbon dioxide actd 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 excaping.
　　According to a weather expert's prediction,the atmosphere will be 3 warmer in the year 2050 than it is today, if man continues to burn luels 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(半球),psooicbly resulting in an alteration of 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 a warming on the scale that will possibly take place in the next fifty years from on burning of fuels.
　　Satellite pictures showthat 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 a long 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(不活动，惰性) 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 heat.
　　68.It can be concluded that a concentration of carbon dioxide in the atmosphere would ___.
　　　A.mean a warming - up im the Arctic
　　　B.raise the temperature of the earth's surface
　　　C.prevent the sun's rays from reaching the earth's surface
　　　D.account for great changes in the climate in the northern hemiphere
　　69.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 variations in the output of solar energy
　　　C.possibly because the ice caps in the poles are melting
　　　D.exclusively due to the effect of the inertia of the earth's climate
　　70.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
