Passage Two
How men first learned to invent words is unknown. All we really know is that men, unlike animals, somehow invented certain sounds to express thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to represent those sounds, and which could be written down. Those sounds, whether spoken or written in letters, we call words.
The power of words, then, lies in their associations--the things they bring up before our minds. Words become filled with meaning for us by experience; and the longer we live, the more certain words recall to us the happy and sad events of our past; the more we read and learn, the larger the number of words that mean something to us becomes.
Great writers are those who not only have great thoughts but also express these thoughts in words which appeal powerfully to our minds and feelings. This attractive use of words is what we call literary style. Above all, the real poet is a master of words. He can express his meaning in words which sing like music, and, by their position and association, can move men to tears. We should therefore learn to choose our words carefully and use them correctly, or they will make our speech dull and silly.
Which of the following did men invent first？
A．Words.
B．Sounds.
C．Signs.
D．Letters.
Both games had been invented a thousand years before. In the first kind of football game ever played, all the men from one village tried to kick a ball into another village. The men of the second village tried to kick the ball into the first. Hundreds of people joined in, running everywhere, running crops and knocking down fences. In time, people agreed on some rules to keep order, but many roles were left open to change. Different rules developed in different places.
When the two colleges met to play football, each followed its own rules. They mixed the games together and invented a new game. A hundred years later we call that game American football.
In what ways do you suppose the game we know now will have changed in another hundred years？
When the two colleges first met to play "football", the players followed ______.
A．the rules of soccer
B．the rules of rugby
C．different rules
D．college rules
Children today not only exist; they have taken over, in no place more than in America, and at no time more than now. It is always Kids' Country here. Our civilization is child-centered, child-obsessed. A kid's body is our physical ideal. In Kids' Country we do not permit middle-age. Thirty is promoted over 50, but 30 knows that soon his time to be overtaken will come.
We are the first society in which parents expect to learn from their children. Such a topsy-turvy (颠倒) situation has come about at least in part because, unlike the rest of the world, ours is an immigrant society, and for immigrants the only hope is in the kids. In the Old Country, that is, Europe, hope was in the father, and how much wealth he could accumulate and pass along to his children. In the growth pattern of America and its everexpanding frontier, the young man was ever advised to GO WEST; the father was ever inheriting from his son. Kids' Country may be the inevitable result.
Kids' Country is not all bad. America is the greatest country in the world to grow up in because it is Kids' Country. We not only wear kids' clothes and eat kids' food; we dream Kids' dreams and make them come true. It was, after all, a boy's game to go to the moon.
If in the old days children did not exist, it seems equally true today that adults, as a class, have begun to disappear, condemning all of us to remain boys and girls forever, jogging and doing push-ups (俯卧撑) against eternity.
The author uses the example of the Renaissance painting to show that ______.
A．adults showed less concern for children than we do now
B．adults were smaller and thinner at that time; but they still had a lot of work to do
C．children looked and acted like adults at that time
D．children were not permitted to appear in family paintings at that time
They still hadn't come when, just before noon, a man eating in our restaurant wanted a cake. I suggested that I run to the bakery next door to get some, and Johnny readily agreed. Going out of our back door, I knocked on the back door of the bakery and bought a few from the baker's helper. That cake was the only one we sold all day.
After closing, Johnny and I sat discussing things with my daughter, who had been out from serving. "An interesting thing happened just before noon," she said. "The owner of the bakery next door came in and ordered a cake of ours. She wanted to compare it with hers."
We know from the passage that ______.
A．the baker next door came to help with the opening
B．the new restaurant did not prepare all its foods
C．the son and the daughter served at the tables
D．the customers enjoyed the cakes very much
First, sometimes early scientists have an idea which is correct, but scientists in later centuries do not believe it. For example, about 270 B. C., a Greek scientist had an idea which we all believe today: The earth moves around the sun. But for the following 1,600 years scientists did not believe this. In their opinion, the sun clearly moved around the earth. They discovered the truth again only in the fifteenth century!
The second fact of history that many people forget is this: Ancient does not mean primitive. For example, the ancient Egyptians knew a great deal about the stars; they used this knowledge to find their way across the oceans. Two thousand years ago a Greek scientist who lived in Egypt calculated the distance around the earth. The results of his calculations were close to the real distance we know today! So the ancients had a great deal of scientific knowledge. They also had skills which equaled the skills of to- day. For example, 1,300 years ago and before, fishermen in Ireland built their boats of wood and leather. Today some fishermen in Ireland still make boats of the same de- sign. They use tools and materials which are not very different from the tools and materitals which their ancestors used. Why？ The ancient design of the boats was good, and with skillful sailors, these boats can sail in all kinds of weather.
Clearly long before the sixteenth century, people had the skill, the knowledge and the equipment which were necessary for long journeys by sea. The world did not have to wait until the sixteenth century for its first explorers!
Which of the following statements is consistent with the passage？
A．According to the writer, we only began to really explore the world in the sixteenth century.
B．In the history of science, people sometimes have to discover a fact a second time.
C．The ancient Egyptians had very little knowledge about the stars.
D．The writer agrees with many Americans and Europeans except for the two facts mentioned in the passage.
After the World war II (27) in 1945, some Americans felt VOA's (28) had to be changed, (29) the Soviet Union (苏联)became the enemy of America. They wanted to reach Soviet listeners. Then VOA began broadcasting in Russian.
In the early years VOA began (30) something new to its broadcast that was (31) "Music USA" , Another new idea came (32) in 1959. VOA knew that many listeners did not know (33) English to completely understand its normal English broadcast. So VOA (34) a simpler kind of English, which uses about 1,500 words and is spoken (35) ,of course, it is Special English.

Asteroids are different forms of the meteoroids that race across the night sky. Most orbits the sun far from Earth and don't threaten us. But there are also thousands of asteroids whose orbits put them on a violent coming course together with Earth.
Buy $ 50 million worth of new telescopes right now. Then spend $10 mil]ion a year for the next 25 years to locate most of the space rocks. By the time we spot a fatal one, the scientists say, we'll have a way to change its course.
Some scientists favor pushing asteroids off course with nuclear weapons. But the cost wouldn't be cheap.
Is it worth it？ Two things experts consider when judging any risk are: 1) How likely the event is; and 2) How bad the consequences if the event occurs. Experts think asteroids big enough to destroy lots of life might strike Earth once every 500,000 years. Sounds pretty rare but if one did fall it would be the end of the world. "If we don't take care of these big asteroids, they'll take care of us. "Says one scientist. "Its that simple."
The cure, though, might be worse than the disease, Do we really want fleets of nuclear weapons silting around on Earth？ "The world has less to fear from doomsday rocks than from a great nuclear fleet set against them. "Said a New York Times article.
What does the passage say about asteroids and meteoroids？
A．They are heavenly bodies similar in nature.
B．There are more asteroids than meteoroids.
C．They are heavenly bodies different in composition.
D．Asteroids are more mysterious than meteoroids.
