Miss Gogers taught physics in a New York school. Last month she explained to one of her classes about sound, and she decided to test them to see how successful she had been in her explanation. She said to them,“Now I have a brother in Los Angeles. If I was calling him on the phone and at the same time you were 75 feet away, listening to me from across the street, which of you would hear what I said earlier, my brother or you and for what reason?”

　Tom at once answered,“Your brother. Because electricity travaels faster than sound waves.”“That’s every good,”Miss Gogers answered; but then one of the girls raised her hand, and Miss Gogers said.“Yes, Kate.”

The week after Jane's birthday, Barbara and Mary were away. Jane decided to have a late birthday party. She telephoned several friends. She asked some to bring records, some to bring food and others to bring something to drink. She rang another friend to see if she could borrow his record player. She herself bought some food and drink to get the party going. She took up all the carpets (地毯) so that they could dance. She did not know whether Barbara and Mary would have approved (赞成), but as long as she was careful, she was sure that they would not mind. She warned the two people in the flat above and invited them down. ?

“Oh, ” said Jane, surprised. “What's all this about? ”

The first guests arrived soon after eight. The music was soon playing loudly and they started dancing. Some of Jane's friends brought other friends with them. As more and more people arrived,the noise increased. People started shouting at each other, so they turned the music up. This made it more difficult to hear each other above the music, so they shouted more loudly. At half past ten the bell rang. “Turn down the music!” someone shouted. “Someone probably called the police.” When Jane opened the door, there was a policeman standing there. She started to apologize, “I'm sorry about all the noise, officer. But you see, it was my birthday last week and I'm having a party.” “Never mind about that, miss. We're here because of something much more important.”

　　In 1961, scientist set up gigantic, sensitive instruments to collect radio waves from the far reaches of space, hoping to discover in them some mathematical pattern indicating that the waves were sent out by other intelligent beings. The first attempt failed, but someday the experiment may succeed.

　　What reason is there to think that we may actually detect intelligent life in outer space？To begin with, modern theories of the development of stars suggest that almost every star has some sort of family of planets. So any star like our own sun （and there are billions of such stars in the universe） is likely to have a planet situated at such a distance that it would receive about the same amount of radiation as the earth.

　　Furthermore, such a planet would probably have the same general composition as our planet; so, allowing a billion years or two or three, there would be a very good chance for life to develop, if current theories of the origin of life are correct.

　　But intelligent life？Life that has reached the stage of being able to send radio waves out into space in a deliberate pattern？Our own planet may have been in existence for five billion years and may have had life on it for two billion, but it is only in the last fifty years that intelligent life capable of sending radio waves into space has lived on earth. From this it might seem that even if there were no technical problems involved, the chance of receiving signals from any particular earth-type planet would be extremely small.

　　This does not mean that intelligent life at our level does not exist somewhere. There are such an unimaginable number of stars that, even at such miserable possibility, it seems certain that there are millions of intelligent life forms scattered through space. The only trouble is, none may be within easy distance of us. Perhaps none ever will be; perhaps the distances that separate us from our fellow “creatures” of this universe will forever remain too great to be conquered. And yet it is conceivable that someday we may come across one of them or, frighteningly, one of them may come across us. What would they be like, these outside-the-earth creatures？

1.What point is the author making by stating that almost every star has some sort of family of planets？

　　A. Sooner or later intelligent beings will be found on one of the stars.

　　B. There must be one or two of the planets on which there are no intelligent beings.

　　C. There are sufficient planets for there to be one that enjoys the same conditions as the earth does.

　　D. One or two billion years later intelligent beings will generate on those planets.

2.What is the main topic of the passage？

　　A. Some probable intelligent life forms on other planets.

　　B. Various stages undergone by the intelligent life on other planets.

　　C. Grounds for probable existence of intelligent life on other planets.

　　D. The possibility of intelligent life existing on our planet.

3.Which of the following can be inferred from the passage？

A. An encounter is probable between people from the earth and intelligent beings from another planet.

B. Though the first attempt failed, scientists did discover the radio waves sent out by other intelligent beings.

C. Other intelligent beings were able to send our radio waves into space well before the last fifty years.

D. It is certain that there are millions of intelligent beings scattered in space but only too far away.

4.According to the author, what is the difference between “we may come across one of them” and “one of them may come across us”？

A. The earth would be dangerously disadvantaged if it is sought after by possibly much more developed creatures.

B. It would prove that there are too many outside-the-earth creatures if “one of them comes across us”.

C. The history of the development of the earth would be proved to be shorter than that of “them” if “they” come across us.

D. it would prove that the distance in between is not so great as we think if “we come across one of them” someday.

Recently Dr. Cleiman has proved that everyone has a daily energy cycle. During the hours when you labor through your work, you may say that you are “hot”. That is true, the time of day when you feel most energetic (full of energy) is when your cycle of body temperature is at its peak(top). For some people the peak comes during the forenoon(上午前). For others it comes in the afternoon or evening. No one has discovered why this is so.

Much family quarrelling ends when husbands and wives realize what this energy cycle means and which cycle each member of the family has.

You cannot change your cycle, but you can learn to make your life fit it better. “Habits can help,” Dr. Cleiman believes. If your energy cycle is low in the morning but you have an important job early in the day, rise before your usual hour, and then you will work better at your low point.

Get off to a slow start which saves your energy. Get up with a lazy yawn(哈欠) and stretch. Sit on the edge of bed before putting your feet on the floor. Avoid the troublesome searching for clean clothes by laying them out the night before.

1. Dr. Cleiman did not explain in the passage ___________.

A. how people can make their life fit their cycle

B. whether everyone has a daily cycle or not

C. why people have their energy cycle of body at different times

D. what will happen in the family if the couple fail to realize which cycle each member has

2.For what reason may husbands and wives quarrel with each other?

A. Either of them gets up late in the morning.

B. Husbands and wives have different cycles of energy.

C. Either of them wants to change the cycle of the other’s.

D. They do not know which cycle they themselves have.

3.According to the passage,____________.

A. one should get up earlier if he wants to work better at his low point in the morning

B. one can change his cycle

C. whenever you feel hot, your energy cycle reaches the highest

D. your cycle must be in the morning if you can get up early

4.Which of the following can save your energy in the morning?

A. Getting up late. B. Jumping out of bed as quickly as possible.

C. Looking for clean clothes. D. Sitting for a while before getting out of bed.

5. Which of the following statements is wrong?

A. If you know your cycle you can make good use of time.

B. If you know your cycle you can change it to fit your life.

C. Father and son do not necessarily have the same cycle.

D. Having a habit of doing something can make people affected less by their energy cycle.
