Scientists in the United States have developed a method that may help to predict earthquakes earlier. They say it could give people who live in deadly earthquake areas enough warning to leave before an earthquake hits.
Currently, the most modem systems for predicting earthquakes find them only a short time before the event. Like most strong earthquakes , the one that hit Southwestern China in May was not identified early enough for people to flee the area. That earthquake killed more than 69,000 people, which rated eight point zero in intensity.
But scientists who study earthquakes are reporting that new technology could measure very small changes in the Earth's surface. Their report was published this month in Nature magazine.
Fenglin Niu is a seismologist in Rice University in Houston, Texas. He and his team performed experiments along California's San Andreas Fault, an area famous for its many earthquakes. The team placed highly sensitive electrical devices about one kilometer below ground in two different places. The devices were able to measure even small changes in air pressure on the Earth's surface. The scientist says such changes are caused when rocks push together, forcing air out of small cracks in the rock. When this happens, seismic waves travel faster than usual through the rock.
The experiment was performed near Parkfield，California. Two earthquakes hit the area in late 2005. The first took place on December 25. A smaller earthquake struck five days later. The scientists noted changes in the Earth's surface about ten hours before the first earthquake struck. That earthquake rated three in intensity. They then found similar changes taking place two hours before the other earthquake struck five days later.
If additional tests confirm the changes are linked to earthquakes ，the scientists believe that their equipment could be used for early warning systems. A system that provides a warning signal ten hours before a major earthquake could help move people from the area and save lives.
The scientists now hope they can find earthquakes with even greater intensity by placing their equipment deeper in the ground. What is the best title for the passage?

To us it seems so natural to put up an umbrella to keep the water off when it rains. But actually the umbrella was not invented as protection against the rain. Its first use was as a shade against the sun!
Nobody knows who first invented it, but the umbrella was used in very ancient times. Probably the first to use it were the Chinese, back in the eleventh century B.C.
We know that the umbrella was used in ancient Egypt and Babylon as a sunshade. And there was a strange thing connected with its use: it became a symbol of honor. In the Far East in ancient times, the umbrella was allowed to be used only by those in high office.
In Europe, the Greeks were the first to use the umbrella as a sunshade. And the umbrella was in common used in ancient Greece. But it is believed that the first persons in Europe to use the umbrella as protection against the rain were the ancient Romans.
During the Middle Ages, the use of the umbrella practically disappeared. Then it appeared again in Italy in the late sixteenth century. And again it was considered as a symbol of power. By 1680, the umbrella appeared in France, and later on in England.
By the eighteenth century, the umbrella was used against rain throughout most of Europe. Umbrellas have not changed much in style during all this time, though they have become much lighter in weight. It wasn’t until the twentieth century that women’s umbrellas began to be made, in a whole variety of colours.
45. According to this passage, the umbrella was probably first invented in ancient _______.
A. China B. Egypt C. Greece D. Rome
46. Which of the following statements is not true about the umbrella?
A. No one exactly knows who was the inventor of the umbrella.
B. The umbrella was first invented to be used as protection against the sun.
C. The umbrella changed much in style in the eighteenth century.
D. In Europe, the Greeks were the first to use the umbrella as a sunshade.
47. A strange feature(特征) of the umbrella’s use is that it was used as _______.
A. protection against rain B. a shade against the sun
C. a symbol of honour and power D. women’s decoration
48. In Europe, the umbrella was first used against the rain ___________.
A. during the Middle Ages B. by the eighteenth century C. in Rome D. in Greece
When he thought of the past, my grandfather would sometimes show us photographs of himself at school. They were brown and faded, and it was hard to believe that the blurred(模糊) figure of the little boy in the short trousers and socks could ever have been Grandfather. Besides, he wore a cap --- all the boys in the photographs wore caps pulled so far forward that half of their faces were obscured. When Grandfather asked us to pick him out from the group, we would surely point to the wrong boy.
On one such occasion my younger sister, aged six, burst into tears when Grandfather proudly guided her finger to the right boy. "How could that boy be you?" she cried. "He should have a beard." We were, of course, all convinced that grandfathers should have beards, preferably white and bushy, like our own grandfather's.
"I was a good scholar," Grandfather would say, wagging his beard over the photographs. "I should have been top of the class if I hadn't had to get up at six every morning to milk the cows and chop the wood, and again when I came home from school."
"But Saturdays? What did you do on Saturdays?"
"Saturdays, if it was fine, I'd be out all day in the fields with the men," replied Grandfather. "And if it was wet, I'd be helping my mother with odd jobs round the house. There wasn't much time for studying."
We all tried hard to imagine what it would have been like to have seen Grandfather getting up at crack of dawn and never, obviously, having a moment for himself. It seemed we had learnt something from what Grandfather had said about his childhood.

Last night was the last game for my eight-year-old son's soccer team. It was the final quarter. The score was two to one, my son's team in the lead. Parents surrounded the playground, offering encouragement.
With less than ten seconds remaining, the ball suddenly rolled in front of my son's teammate, Mickey O'Donnel. With shouts of "Kick it!" echoing (回响) across the playground, Mickey turned around and gave it everything he had. All around me the crowd erupted (沸腾). O'Donnel had scored!
Then there was silence. Mickey had scored all right, but in the wrong goal, ending the game in a tie. For a moment there was a total hush. You see, Mickey has Down syndrome (综合症) and for him there is no such thing as a wrong goal. All goals were celebrated by a joyous hug from Mickey. He had even been known to hug the opposing players when they scored. 
The silence was finally broken when Mickey, his face filled with joy, hugged my son tightly and shouted, "I scored! I scored. Everybody won! Everybody won!" For a moment I held my breath, not sure how my son would react. I need not have worried. I watched, through tears, as my son threw up his hand in the classic high-five salute and started chanting, "Way to go Mickey! Way to go Mickey!"

.Life gets noisier every day and very few people can be free from noise of some sort or another. It doesn't matter where you live--in the middle of a modern city, or a faraway village--the chances are that you' 11 be disturbed by jet planes, transistor radios, oil - powered engines, etc. We seem to be getting used to noise, too. Some people feel quite lonely without background music while they' re working.
Scientific tests have shown that total silence can be a very frightening experience for a human being. However, some people enjoy listening to pop music which is very loud, and this can do harm to their eardrums(耳鼓). The noise level in some discos is far above the usual safety level for heavy industrial areas.
One recent report about noise and concentration(专心) suggested that although a lot of people say that any noise disturbs their concentration, what really influences their ability to concentrate is a change in the level of noise. It goes on to say that a background noise which doesn't change too much(music, for example) may even help people to concentrate.
56. According to this passage, the noise pollution __
A. has become the worst in the countryside B. has become better in big cities
C. has spread from cities to villages D. has been controlled in modern cities
57. What does background music refer to?
A. Music played while people are working.
B. Music played in the backyard.
C. Noise that continues while you' re listening to other noises.
D. Music used to help people to concentrate.
58. Some people have their hearing harmed __
A. while listening to pop music 
B. in complete silence
C. when speaking loudly D. while watching TV
59. Which of the following isn't included among the things causing noise?
A. trucks B. motorcycles C. electric engines D. jet planes
60. Scientists have discovered that what prevents people from concentrating on something is
A. all kinds of noise B. great changes in the level of noise
C. background noise D. popular music
