问答题练习17　　Five hundred years ago, news of important happenings—battles lost and won, kings or rulers overthrown or killed—took months and even years to travel from one country to another. The news passed by word of mouth and was never accurate. Today we can read in our newspapers of important events that occur in faraway countries on the same day they happen.

单选题According to the passage, which of the following is TRUE?A Freedman and his colleagues hired 400,000 Americans to collect data.B About four hundred thousand Americans worked for Freedman's team full time for 13 years.C People who took part in Freedman's research are about 50 to 70 years old.D People who are 50 to 70 years old seldom drink coffee

40 years ago the idea of disabled people doing sport was never heard of. But when the annual games for the disabled were started at Stoke Mandeville, England in 1948 by Sir Ludwig Guttmann, the situation began to change. Sir Ludwig Guttmann, who had been driven to England in 1939 from Nazi Germany, had been asked by the British government to set up an injuries center at Stoke Mandeville Hospital near London. His ideas about treating injuries included sport for the disabled. In the first games just two teams of injured soldiers took part. The next year, 1949, five teams took part. From those beginnings, things have developed fast. Teams now come from abroad to Stoke Mandeville every year. In 1960 the first Olympics for the Disabled were held in Rome, in the same place as the normal Olympic Games. Now, every four years the Olympic Games for the Disabled are held, if possible, in the same place as the normal Olympic Games, although they are organized separately. In other years Games for the Disabled are still held at Stoke Mandeville. In the 1984 wheelchair Olympic Games, 1064 wheelchair athletes from about 40 countries took part. Unfortunately, they were held at Stoke Mandeville and not in Los Angeles, along with the other Olympics. TheGameshavebeenagreatsuccessinpromotinginternationalfriendshipandunderstanding, and in proving that being disabled does not mean you can't enjoy sport. One small source of disappointment for those who organize and take part in the games, however, has been the unwillingness of the International Olympic Committee to include disabled events at Olympic Games for the able-bodied. Perhaps a few more years are still needed to convince those fortunate enough not to be disabled that their disabled fellow athletes should not be excluded. From the passage, we may conclude that the writer is __________ .A.one of the organizers of the game for the disabled B.a disabled person who once took part in the games C.against holding the games for the disabled D.in favor of holding the games for the disabled

共用题干 Earth Rocks onMost of the time,the ground feels solid beneath our feet. That{S comforting. But it's also misleading because there's actually a lot going on underground.Masses of land(called plates)slip,slide,and bump against each other,slowly changing the shape of continents and oceans over millions and billions of years.Scientists know that Earth formed about 4.5 billion years ago.They also know that our planet was hot at first. As it cooled , its outermost layer , called the crust（地壳）, eventually formed moving plates. Exactly when this shift happened,however,is an open question.Now,an international group of researchers has an answer. They'ye found new evidence suggesting that Earth's crust started shifting at least 3.8 billion years ago.The new estimate is 1.3 billion years earlier than previous ones.Not long before 3. 8 billion years ago,lots of asteroids（小行星）were hitting Earth,keeping its crust in a hot,melted state.After the hard crust formed,much of it sank at various times into the planet's hot in- sides.There,it melted before returning to the surface.In some places,however,the crust never sank.One of the oldest such places is in Greenland,in an area called the Isua supracrustal（上地壳） belt. The rocky crust there is between 3. 7 and 3. 8 billion years old. The belt was once part of the seafloor,but now it is exposed to air.The researchers recently took a close look at the Isua supracrustal belt. They noticed long,parallel cracks in the rock that have been filled in with a type of volcanic rock.To explain this structure,the scientists propose that tension in the crust caused the seafloor to crackopen long ago. Hot , liquid rock , called magma（岩浆）,flowed up slowly from deep inside Earth to fill the cracks.Finally,the whole area cooled,forming what we see today.That explanation,plus chemical clues inside the rock,suggests that the Isua supracrustal belt was once part of a plate under the ocean,beginning around 3.8 billion years ago.It took a long time for the melted crust to become hard.A:RightB:WrongC:Not mentioned
