It amazed me-every time I saw Joe he was smiling.It didn't matter whether he had to stop at a stop

light,or if he was the seventh person in line at the bank,and the teller (出纳员) ended her job just before

he got there.Joe always smiled.It made me wonder why he always seemed so happy.

Having observed Joe with other people,I noticed something else too.Joe asked people how they were doing,and really seemed to listen to their answers.He showed pity tosomeone who was hurting,and had

kind words,and offered to help in any way he could.

It made me think.What if I tried to smile more?An experiment began when I went to the supermarket.

I smiled as I went up and down the supermarket and people I didn't even know smiled back at me.Some

even spoke!The little kid in the cart who was giving his mother a hard time saw me smile;he stopped

talking and then made a shy attempt at a smile.The man in the cart for the disabled needed help to reach

for something,and I got it for him.The smile even transferred (转移) over to him,and he thanked me.

As I drove home,I was smiling.Now I know a smile is a small thing,but what if we all tried to smile a

few more times each day?I couldn't believe how great I felt.Nothing in my life had changed,but maybe it

had.What I had learned was that such a small thing could lift not only my spirits,but also the spirits of those around me.So smile!

第5题

听力原文: When you live in an apartment building, where only wall separates you from your neighbors, everyone needs to be considerate of each other. Thats not what happened in my apartment building. Someone was always leaving the clothes in the washers and dryers in the laundry room. I got tired of running up and down the stairs to see if the clothes had been removed, so I could start my own one. Obviously someone else got tired, too. Because one day, someone took clothes from the washer and dryer, and dumped them in the corner. This act started a battle of letters posted on the wall of the laundry room. The first letter was from Mindy Lance who was really angry that her clothes had been removed from the washer and dryer, and dumped. She then threatened to dump everybody elses clothes she herself found in the washer and dryer. Mindy Lances letter enraged other residents and they posted the letters to her. Eventually, Mindy began to behave properly but hard feelings remained. The problem couldnt have been resolved better. If residents had informed the building manager, she then could inform. all residents that the clothes should be removed from the washers and dryers within 50 minutes after their wash is done. Those who refuse to obey might not have their leases renew. That could be a fare consent solution. Neighbor problems may sometimes seem inevitable, but its important to resolve them fairly. 20. What does the speaker think residents in an apartment building need to be? 21. What started a battle of letters in the laundry room? 22. What does the speaker think might be a better way to resolve the problem?21.

A.Someone dumped the clothes left in the washer and dryer.

B.Someone broke the washer and dryer by overloading them.

C.Mindy Lance"s laundry blocked the way to the laundry room.

D.Mindy Lance threatened to take revenge On her neighbors.

听力原文: Before World War n, we spent our summer holidays in Hungary. I have only the dim memory of the house we lived in, of my room and my toys. Nor do I recall clearly the large family of grandparents, aunts, uncles and cousins who gathered next door. But I do have a clear memory of the dogs, the farm animals, the local birds, and above all, the nature. Im a naturalist, not a scientist. I have a strong love of the natural world and my enthusiasm has led me into varied investigations. I love discussing my favourite topics and enjoy burning the midnight oil while reading about other peoples observations and discoveries. Then something happens and brings these observations together in my conscious mind. Suddenly you fancy you see the answer to the riddle, because it all seems to fit together. This has resulted in my publishing 300 papers and books, which some might honor with the title of scientific research. But curiosity, a keen eye, a good memory and enjoyment of the animal and plant world do not make a scientist: one of the outstanding and essential qualities required is self-discipline, a quality I lack. A scientist requires not only self-discipline but hard training, determination and a goal. A scientist, up to a point, can be made. A naturalist is born. If you can combine the two, you get the best of both worlds. Questions 23 to 25 are based on the passage you have just heard. 23. Why couldnt the speaker remember his relatives clearly? 24. What can be inferred about the speaker from the passage? 25. Why did the speaker think he was a naturalist rather than a scientist?23.

A.He was first of all a scientist.

B.He was not only a naturalist but also a scientist.

C.He was no more than a born naturalist.

D.He was a scientist as well as a naturalist.
