The concept of solitude (独处) in the digital world is almost non-existent. In the world of digital technology, e-mail, social networking and online video games, information is meant to be    【小题1】  . Solitude can be hard to discover once it has been given up. In this respect, new technologies have    【小题2】   our culture.
The desire to be connected has brought solitude to a(an)    【小题3】   as we’ve known. People have become so    【小题4】   in the world of networks and connections that one can often be contacted even if they’d rather not be. Today we can talk, text, e-mail, chat and blog to share our ideas, not only from our    【小题5】  , but from our mobile phones as well.  
Most developed nations have become    【小题6】   on digital technology simply because they’ve grown accustomed to it, and at this point not    【小题7】   it would make them an outsider.    【小题8】  , many jobs and careers require people to be    【小题9】  . From this point of view, technology has changed the culture of work. Being reachable might feel like a    【小题10】   to those who may not want to be able to be contacted at all times.  
I suppose the positive side is that solitude is still possible for anyone who really wants it. Computers can be shut down and mobile phones can be turned off. The ability to be “connected” and “on” has many    【小题11】   , as well as disadvantages. Travelers have ended up    【小题12】   on mountains, and mobile phones have saved countless lives. They can also make people feel    【小题13】  and forced to answer unwanted calls or reply to unwanted texts.
Attitudes towards our connectedness as a society    【小题14】   according to different generations. Some find today’s technology a gift. Others consider it a    【小题15】  . Regardless of anyone’s view on the subject, it’s hard to imagine what life would be like without keeping up with the advancements in technology.

One of the most remarkable things about the human mind is our ability to imagine the future. In our   16  we can see what has not yet happened．For example, while we are looking forward to visiting a new place or country, we   17  what it will be like. We predict the   18  people will eat, dress and act. Of course, we do not always predict things correctly. Things are often very different from the way we   19  them to be.
One of the   20  dreams in history is the dream of the German scientist, Kekule, who had been   21  to work out a very difficult problem in physics. He had   22  and analyzed the problem from every angle for days, but there seemed to be no way of   23  out the answer. Then one night he went to bed and dreamed．When he   24  up, he realized that he knew the answer. He had solved the problem in his   25 .
The hypnotist(催眠者) sat in the chair opposite him and spoke   26 : I want you to concentrate on my voice. Think about nothing. You know nothing but my voice. And as you pay attention to my voice, your   27  will get heavier. Soon you’ll be asleep.
You will hear my voice and   28  my words, but your body will be asleep, your eyes are too heavy. You are almost asleep, and when you wake up you will   29  nothing.
You will forget everything. Now I am going to   30  slowly from one to five. One, two, three, four, five.

The massive magnitude（震级） 8.8 earthquake that struck the west coast of Chile moved the entire city of Concepcion at least 10 feet to the west, and moved other parts of South America as far apart as the Falkland Islands and Fortaleza, Brazil.
These measurements, produced from data gathered by researchers from four universities and several agencies, paint a much clearer picture of the power behind this earthquake, believed to be the fifth-most-powerful since instruments have been available to measure earthquake.
Buenos Aires, the capital of Argentina moved about 1 inch to the west. And Chile's capital, Santiago, moved about 11 inches to the west-southwest. The cities of Valparaiso and Mendoza, Argentina, northeast of Concepcion, also moved.
The quake's epicenter (震中) was in a region of South America that's part of the so-called “ring of fire,” an area of major seismic（地震的） stresses which encircles（环绕，包围） the Pacific Ocean. All along this line, the plates on which the continents move press against each other.
Mike Bevis, professor of earth sciences at Ohio State, has led a project since 1993 that has been measuring crustal（地壳的）movement in the Central and Southern Andes. The effort is called the Central and Southern Andes GPS Project, or CAP.
Ben Brooks, an associate researcher with the School of Ocean and Earth Science and Technology at the University of Hawaii, said that the event, offers a unique opportunity to better understand the seismic processes that control earthquakes.
“We now have modern, precise instruments to evaluate this event, and because the site borders a continent, we will be able to get evidences of the changes it caused.” said Brooks.

Most people think of birds as feathered animals that fly. Scientists,   36 , do not define (给…下定义) birds as animals that fly, because some birds do not. Of the 10,000 or so species of birds, 46 cannot   37 . Flight plays a key role in   38  for most birds. It allows them to find food over a   39  area and to get away from enemies. Ancestors of flightless birds may have   40   their ability to fly because they had no regular predators (捕食者) or did not need to fly to find food. Rather than fly, some of these birds developed other   41  to catch food and avoid enemies. Two examples of   42  birds are penguins and ostriches.
  43  birds that fly, penguins do not have wide wings or large feathers. In order to catch the fish they feed on, penguins use their powerful wings to swim   44 . And when they swim,  they look as if they are flying through the water. The   45  of penguins’ bodies makes it possible for them to dive deep underwater,  46  their thick feathers protect them from the cold.
Ostriches are known for their long legs, long necks, and large size. To   47  themselves, they stay in groups and use their excellent sight and hearing to   48  enemies.

In the past, man didn’t have to think about the protection of his environment. There were few people on the earth, and natural resources seemed to be   1 .
Today things are  2 , and the world has become too  3  . We’re using up our natural resources too quickly, and at the same time we are   4  our environment with dangerous chemicals. If we continue to do this, human life on the earth   5 survive.
Everyone 6 today that if too many fish are taken from the sea, there will soon be none left. Yet, with modern fishing  7, more and more fish are caught. We know that if too many trees are cut down, 8  will disappear and nothing will grow on the land. Yet, we 9  to use bigger and more powerful machines to  10 more and more trees.
We know that if rivers are polluted with waste products from factories, we’ll die.   11 , in most countries wastes are   12 put into rivers or into the sea, and there are  13  laws to stop this.
We know, too, that if the   14  of the world continues to rise at the present rate, in a few years there will not be enough  15  . What can we do to solve these problems?
If we eat more vegetables and less  16 there will be more food available for every one. Land that is used to grow crops 17 five times more people than land where animals are kept.
Our natural resources will   18  longer if we learn to recycle them.
The world population will not rise so quickly if people use modern methods of birth 19 .
Finally, if we educate people to think about the problems, we shall have a better and cleaner   20 in the future.

Many of the world’s pollution problems have been caused by the crowding of large groups of people into the cities. Supply for the needs of the people leads to further   1  by industry. If the rapid increase of world 2  continues at the present rate, there may be much greater 3  to human beings. Some scientists 4  of the increase in numbers of people as “population pollution（人口公害）”.
About 2, 000 years ago, the world population was about 250 million. It  5 a billion in 1850. By 1930 the population was two billion. It is now six billion. It is  6 to double by the year 2020. If the population  7  to grow at the same rate, there will be 25 billion people in the 8   a hundred years from now.
Man has been 9   the earth’s resources more and more 10   over the past years. Some of them are almost gone. Now many people believe that man’s 11   problem is how to control the 12   of the population. The material supplies in the world will be far from enough to  13  the human population if the present rate of increase continues. There is already over-crowding（过分拥挤）in many cities and  14  in some countries. Many people believe that human survival（生存） in the future  15  on the answer to the question.

In 1990 a report was published about what the earth might be like 20 years from then on. The report was a result of a three-year  36 .?
According to the report, the picture of the earth in the year 2010 is not a  37  one. The world will be more  38  because the population will continue to grow . The population could be  39  6 300 million, almost 2 115 million more than in 1985 .More people would move into cities, especially cities in  40  countries . Cities like Cairo and Jakarta probably would  41  have 15 million by then .
Food production will  42  , but not enough to feed all the people . Farmers will grow 90% more food than they did in 1985,  43  most of the increase would be in countries that
 44  produce enough food for their people . Little increase is  45  in South Asia, Africa and the Middle East . Poor farming ways are 46  large areas of crop land, changing farms into deserts . More farmland is  47  as cities become larger and more houses are built . 48  will get worse as industrial countries burn more coal and oil .?Many of the world’s  49  could disappear as more and more trees are cut down . Energy will continue to be a serious problem . The experts say their picture of the earth for the year 2010  50  . They only carried out the situation that  51  today . By changing the situation, by  52  the problems, the picture can be changed . There is  53  time for the nations of the world to work  54  a plan of action . But they warned that  55  too long to make decisions would greatly reduce the chances of success .?

A farmer found a wounded eagle (鹰) in his field. He was so   26   that he took it home and cleaned its wounds. After that he placed it  27  in the yard, in the hope that it    28    recover soon.
Strangely enough, the eagle soon got used to the    29   of all the chickens in the yard. It learned to    30    from side to side like chickens, and eat happily from a trough (食槽). For many years, the eagle    31    his new life on the farm.
Then one day, one of the farmer’s friends pointed to the playing    32   and asked, “  33   is that eagle acting like a chicken?” The farmer told him what had   34  , and the friend felt quite   35  .
“I can’t believe that!” said the friend. “It should fly in the    36   , not live here!” He picked up the eagle, and   37   it into the air. The eagle was  38  , and cried loudly. Then it just fell down on the ground.
That night, the friend could   39   sleep as he remembered the chicken-like eagle. The next morning, he headed back to the farm for another   40  . This time he carried the eagle to the   41   of a nearby mountain.
When he stood at the highest place of the mountain, he looked into its eyes and shouted, “Don’t you   42   ? You weren’t made to live like a chicken!” As he   43   the eagle up, he made sure it was facing into the bright   44   of the rising sun. Then he    45    tossed (抛) the bird into the sky. This time the eagle opened his wings, and disappeared into the clouds.

It is interesting how NASA(美国航空航天管理局)chose their astronauts for landing them on the moon. They chose men  26  the age of twenty and thirty-five. There were about fifty of them, Many were  27  air pilots.  28 were scientists with two or three degrees. NASA telephoned each man they were going to choose; told him the plans and the  29  they might get in. They then asked him if he was willing to be trained as an astronaut. “How could any man  30 such an exciting job?” One of them said, “Dangerous? Of course. It’s dangerous  31 most exciting”
The health and physical condition of  32 was, of course, very necessary.  33  those in very good health and physical condition were chosen.
While being trained to be astronauts. They went through many  34 . They studied the star and the moon, and they also studied geology, the science of rocks. This was necessary  35  astronauts would have to look for rocks on the moon. They would try to find rocks which might help to tell the  36 of the moon. They were all  37 to fly in helicopters （直升飞机）。These helicopters landed  38 down to give them some experience of the way the spaceship would  39 land on the moon , They were also taught the  40  facts about the conditions in space. They learnt all the technical details of the spaceships and rockets. They visited the scientists and engineers who  41 them. They visited the factories where they were  42. They learnt how every 43 of a space-ship and its instruments work. They also learnt every detail of ground-control  44 .
In a word, to be chosen as an astronaut. One must be in good health,  45  in science and good at piloting.
