My husband and I married in a large country town. The morning after the wedding, we were going back to my parents’ home. As my husband was packing, I noticed he’d placed my 31 in the luggage crate(大木箱) on top of the car. I said that maybe he should 32 it. He turned and said, “It’ll be 33 . Trust me! It won’t come off.”

Halfway home we had a car come racing up beside us and the driver 34 us down. She said she’d seen a red suitcase on the side of the road several kilometers back and was 35 if it was ours. We looked 　36 and, to our 37 , discovered that the case had flown off.

　　　 We raced back, but the case was 38 . We visited the local police station, but as the road was a common link between several towns, we weren’t very 39 . We put it all down to our bad 40 .

　　　 Seven years later, my father got a(n) 41 from a lady asking if I’d lost a red suitcase. Her husband had 42 the case abandoned on the side of the road. He assumed he’d be able to find an address or name somewhere inside and 43 it later. On opening the case, they’d found the wedding cards, no address, and no way of 44 who we were. They’d spent seven years moving around the area, always taking the suitcase with them.

　　　 They were about to 45 again and decided to give it one more 46 before leaving. This time, on opening the jewellery box, they 47 a piece of paper folded up in it——my birth certificate. 48

that my parents were still in the district, they started to ring around. The suitcase was 49 returned to us.

　　　 This couple’s 50 and persistence(坚持) in finding us is truly admirable.

But one woman has    3    all that. She has lived with chimpanzees in the African forest for more than 20 years and made great    4   .This woman is Jane Goodall. She was born in London, England, in 1934.Goodall’s lifelong    5    in animals began at an early age. By the age of 10 or 11,Goodall    6    going to Africa to live with animals.

She told her that if she really wanted something, she should work hard, take advantage of   9   and never give up looking for a way.

When a close friend invited Goodall to Kenya in 1957,she readily   10   .Within a few months of her arrival she met the famous anthropologist(人类学家) Dr. Louis Leakey, who soon decided that Goodall was the    11    person he was looking for to begin a    12    of wild chimpanzees on the shore of Lake Tanganyika in Tanzania.

In July 1960, Goodall arrived at Gombe National Park in Tanzania. At the beginning, studying the chimpanzees was not    13   for her. The animals fled from her   14   , so it took months for her to get close to them. With a strong   15   , she searched the forest every day, trying not to get too close to the chimpanzees too   16   . Gradually the chimpanzees became used to her presence.

She discovered many things of chimpanzees during her first years at Gombe National Park. In October 1960,she observed a chimpanzee making and using   17    to fish for termites (白蚁).This discovery threw    18    on the popular idea at the time that Man was the world’s only toolmaker. The longer Goodall’s research continues, the more it becomes obvious that chimpanzees are very   19    to humans.

Since the mid-1980s, Goodall has been lecturing around the world to raise people’s sense about environmental    20   . “Let’s live in the new age with hope, respect for all living things, understanding and love,” she said.

Dogs are social animals and without proper training, they will behave like wild animals. They will soil your house, destroy your belongings, bark excessively, fight other dogs and even bite you. Nearly all behavior problems are perfectly normal dog activities that occur at the wrong time or place or are directed at the wrong thing. The key to preventing or treating behavior problems is learning to teach the dog to redirect its normal behavior to outlets that are acceptable in the domestic setting.

　　One of the best things you can do for your dog and yourself is to train its obedience. Obedience training doesn’t solve all behavior problems, but it is the foundation for solving just about any problem. Training opens up a line of communication between you and your dog. Effective communication is necessary to instruct your dog about what you want it to do.

Training is also an easy way to establish the social rank order. When your dog obeys a simple request of “come here, sit,” it is showing obedience and respect for you. It is not necessary to establish yourself as top dog or leader of the pack（群）by using extreme measure. You can teach your dog its subordinate（从属的）role by teaching it to show submission to you. Most dogs love performing tricks for you to

pleasantly accept that you are in charge.

　　Training should be fun and rewarding for you and your dog. It can enrich your relationship and make living together more enjoyable. A well-trained dog is more confident and can more safely be allowed a greater amount of freedom than an untrained animal.
