Dear Dr.Bamford,

  I know you are a famous scientist who has done great work on cloning animals.Please excuse me for writing to you, but I need your help.Let me explain.

  I am a 58-year-old man.I’m very rich.I live in a large house.My wife died three years ago; we didn’t have children.

  So, am I lonely? No, because Cindy is with me.Every night we eat dinner together and watch TV.Cindy sits beside me and I feel very happy.I’m coaxed with her beautiful green eyes.She’s also very smart.Sometimes she thinks only about herself.But that’s what I like about her.She is quite a beautiful Siamese cat.There is no other cat like her in the whole world.

  These days I worry about losing Cindy.She is getting older and older.Cats don’t live so long as humans, of course, so she will die before I do.I cannot imagine my life without Cindy.

  Well, why not get another cat after Cindy dies? Impossible!No other cats ever replace her.

  I have been thinking about this:Clone Cindy.Scientists are able to clone sheep and mice and other animals.They should be able to clone cats without much difficulty.Luckily, I am a rich man.I don’t care how much money I will spend cloning Cindy.I think it’s ok to clone pets.It’s not cloning humans.

Sincerely,

  Finally the great day came. Helen went to the airport to meet her parents. The last time Helen saw her family was two years ago. At the airport, Helen gave her parents clothing, and her parents gave her the camera she wanted so much. She didn't lose any time and began to take pictures immediately.

Don' t expose the film. I have pictures in there and I don't want to lose them.”

  I made a pledge(誓言)to myself on the way down to the vacation beach cottage.For two weeks I would try to be a loving husband and father.Totally loving.No ifs, ands or buts.

  The idea had come to me as I listened to a talk on my car radio.The speaker was quoting a biblical(圣经的)passage about husbands being thoughtful of their wives.Then he went on to say,“Love is an act of will.A person can choose to love.”To myself, I had to admit that I had been a selfish husband.Well, for two weeks that would change.

  And it did.Right from the moment I kissed Evelyn at the door and said,“That new yellow sweater looks great on you.”

  “Oh, Tom, you noticed,”she said, surprised and pleased.Maybe a little puzzled.

  After the long drive, I wanted to sit and read.Evelyn suggested a walk on the beach.I started to refuse, but then I thought,“Evelyn’s been alone here with the kids all week and now she wants to be alone with me.”We walked on the beach while the children flew their kites.

  So it went.Two weeks of not calling the Wall Street firm where I am a director; a visit to the shell museum though I usually hate museums.Relaxed and happy, that’s how the whole vacation passed.I made a new pledge to keep on remembering to choose love.

  There was one thing that went wrong with my experiment, however.Evelyn and I still laugh about it today.On the last night at our cottage, preparing for bed, Evelyn stared at me with the saddest expression.

  “What’s the matter?”I asked her.

  “Tom,”she said in a voice filled with distress(悲痛),“do you know something I don’t?”

  “What do you mean?”

  “Well…that checkup I had several weeks ago…our doctor…did he tell you something about me?Tom, you’ve been so good to me…Am I dying?”

It took a moment for it all to sink in.Then I burst out laughing.

  “No, honey,”I said, wrapping her in my arms.“You’re not dying; I’m just starting to live.”

  Don’t be surprised if you find yourself sitting next to a Fido on your next flight.Several airlines now allow dogs and cats to fly in airplane cabins with people.

  Those in favor of the pet-friendly policy say it’s safer for dogs and cats to fly first class.They point out that animals could get injured while traveling in an aircraft’s cargo area with suitcases.

  However, the idea of sharing a flight with furry friends does not “fly” with everyone.Some people are allergic(过敏的)to animals.They say flying with pets could make them sick.

  What do you think? Should dogs and cats be allowed to fly in an airplane cabins? WR News student reporters Isabella Pena and Peter Brosnan each fetched a side.

  YES.Animals can get hurt flying in cargo areas.

  Pets should be allowed to fly in airplane cabins with their owners.Did you know that there have been injuries to animals flying in cargo? Cargo areas are not equipped to deal with situations such as delays or extreme temperatures.

  Also, dogs and cats can feel nervous in new situations.“Pets can feel anxious and stressed when they’re expecting new, scary things without the comfort of their owners,” explains Nicole Kagan, a vet from Manhattan Beach, Calif.

  The pets’ stress can be reduced if they are allowed to travel with their owners in an airplane cabin.That is especially important for pets on longer flights.

Isabella Pena,

California

  NO.Some passengers are allergic to pets.

  I really like dogs and cats, and that is why I don’t think it is a good idea for them to fly in airplane cabins with people.Pets can be afraid of strangers, and that could cause them to bark.The noise could be upsetting to everyone on board.

  Also, for passengers who have allergies or asthma(哮喘), sitting next to pets can be dangerous.“I could put myself at risk for an asthma attack,” explains Kristina Krops, a teacher at Helen Morgan School in Sparta, N.J.“Passengers need to feel safe.” If people really need their dogs and cats to travel, they can have them fly on a special airline just for pets, such PET Airways.

  What do we think with? Only the brain? Hardly, the brain is like a telephone exchange. It is the switch-board (电话总机) , but not the whole system. Its function (功能) , is to receive incoming signals, make proper connections, and send the messages through to their destination (目的地) . For efficient (有效的) service, the body must function as a whole.

  But where is the “mind” ? Is it in the brain? Or perhaps in the nervous system? After all , can we say that the mind is in any particular place? It is a function , an activity. Aristotle , twenty-three hundred years ago , observed that the mind was to the body that cutting was to the ax (斧) . When the ax is not in use, there is no cutting. So with the mind , “Mind , ” said Charles H. Woolbert , “is what the body is doing. ”

  If this activity is necessary for thinking, it is also necessary for carrying thought from one person to another. Observe how people go about the business of ordinary conversation. If you have never done this painstakingly , you have a surprise in store , for good conversationalists are almost constantly in motion. Their heads are continually nodding and shaking sometimes so vigorously (有力的) that you wonder how their necks can stand the strain (拉紧).

  Even the legs and feet are active. As for the hands and arms , they are seldom still for more than a few seconds at a time.

  These people, remember, are not making speeches. They are merely common folk trying to make others understand what they have in mind. They are not conscious of (意识到) movement. Their speech is not studied. They are just human creatures in a human environment, trying to adapt (适应) themselves to a social situation. Yet they talk , not only with oral language , but with visible actions that involve (包括) practically every muscle in the body.

  In short, because people really think all over, a speaker must talk all over if he succeeds in making people think.

1.Which of the following is the best title for the passage?

[  ]

A.Bodily Communication

B.Bodily Actions

C.Spoken Language

D.Conversations

2.Which of the following statements would the author agree with?

[  ]

A.Thinking is social phenomenon(现象).

B.Thinking is only a brain function.

C.Thinking is a function of the nervous system.

D.Thinking is the sum total of bodily activity.

3.In communication , it is necessary not only to employ speech , but also ________.

[  ]

A.to speak directly to the other person

B.to employ a variety of bodily movements

C.to be certain that the other person is listening

D.to pay great attention to the other person's actions

4.It can be inferred from the passage that the basic function of bodily activity in speech is to ________.

[  ]

A.make the listener feel moved

B.make the speaker understood

C.emphasize .the speaker's spoken words

D.pass the speaker's implied meaning to the listener

5.Which of the following is TRUE?

[  ]

A.The brain is compared to a telephone exchange.

B.The mind is an activity of the nervous system.

C.Some people remain still while talking to others.

D.Many people move their bodies on purpose while talking.
