Unit5Ⅰ.Lead-in1.People keep pets for a variety of reasons. Some feel lonely and need company. Other peoplekeep pets for security. Still others buy pets just to be in fashion. Finally, some people keep animals at home just out of love or pity. Their hearts are full of love, which pours out naturally for animals as well as humans.2.Most people prefer dogs to cats. Dogs are more loyal to their owners than cats are. Also, dogsare more intelligent than cats. They can carry out human instructions and perform fairly complicated functions. Moreover, with its strength and agility, the dog is capable of protecting the house and its master. However, I wouldn't go as far as to claim that cats are worthless.Thanks to their soft fur, meek tempers and cute faces, they are often ladies' favorites.3.It's hard to arrive at a conclusion on this question. It is obvious that if a pet like a cat is kept inthe apartment without much chance of going out, it looks sad and inactive. Without proper physical exercise and enough exposure to the sun, it tends to become weak. However, they also have their compensation. In a human household pets are normally well fed. I should like to point out that a pet's intelligence is also an important factor. A dog or a cat may be intelligent enough to feel lonely, but I doubt whether less intelligent animals like a tortoise or fish can feel the difference between the human home and the wild or whether they can develop a feeling of loneliness, sadness or homesickness. In any case, a human home can provide them with better living conditions.4.In my opinion, it is all right for us to eat meat such as pork, beef and chicken. To explain this,let me quote from the movie "The Lion King". The father lion tells his son that it is all right for them to eat the antelope: "When we die, our bodies become the grass. And the antelope eat the grass. And so we are all connected in the great Circle of Life." In the case of dog meat, people's opinions seem to vary. I think with the progress of human civilization and improvement of the living standards, we should discard the habit of eating dogs, since they are so intelligent and so loyal to us.Ⅲ.Listening InTask1:Dogs aren't allowed here!Manager: I'm sorry, Miss, but dogs aren't allowed in this theater.Mary: But I have a ticket for him.Manager: I'm very sorry, but animals aren't permitted.Mary: You don't understand.

I promise you that this dog isn't like any other dog you've ever seen.Manager: Well... all right. I'll let you go in, since the theater is almost empty tonight. But your dog will have to behave himself, or you will have to leave.Mary: Thank you very much.Task2:Put the cat out!A couple was going out for the evening to celebrate the wife's birthday. While they were getting ready, the husband put the cat out. The taxi arrived, and as the couple walked out of their home, the cat ran back into the house. Not wanting their cat to have free run of the house while they were out, the husband went back upstairs to chase the cat out. The wife, not wanting it known that the house would be empty, explained to the taxi driver, "He's just going upstairs to say goodbye to my mother." A few minutes later, the husband got into the car, and said, "Sorry it took so long. The stupid old thing was hiding under the bed, and I had to poke her with a stick to get her to come out!"Task3:A Sudden Change in the Parrot's AttitudeA young man named John received a parrot as a gift. The parrot had a bad attitude and an even worse vocabulary. Every word out of this bird's mouth was rude. John tried every method to change the bird's attitude by constantly saying polite words, playing soft music, and anything he could think of to set a good example. Nothing worked. Finally, John got fed up and he yelled at the parrot. And the bird yelled back. John shook the parrot, and the bird got angrier and ruder. Finally, in a moment of desperation, John put the bird in the refrigerator freezer. For a few minutes, John heard the bird scream and kick. Then suddenly there was silence. Not a sound for over a minute. Fearing that he'd hurt the bird, John quickly opened the door to the freezer. The parrot calmly stepped out and said, "I believe I may have offended you with my rude language and actions. I am truly sorry, and I will do everything I can to correct my poor behavior."John was greatly surprised at the bird's change of attitude. As he was about to ask the parrot what had caused such a sudden change in his behavior, the bird continued, "May I ask why you put the chickens there and what they did wrong?"Ⅴ.Let’s TalkAn Intelligent DogA black dog walked into a butcher's shop with a five-dollar bill in his mouth. He spent several minutes looking at the meat on display. He finally fixed his eyes on the lamb chops and barked, showing that he wanted to buy some of them. The butcher, thinking the dog wouldn't know the difference, picked out the worst chops. The dog barked angrily and continued to bark until the butcher selected the finest chops. After the butcher took the money from the dog's mouth, the dog picked up the chops and left the shop.The butcher was deeply impressed and decided that he would like to own a clever dog like that. He closed up shop and followed the dog to see where it went. The dog entered an apartment house, climbed to the third floor, and began to scratch on the door. With that, the door opened and an angry man started yelling at the dog. As he did so, the butcher stepped forward to ask the man to stop. "What are you doing? That's the smartest animal I've ever seen! Surely it doesn't deserve this kind of treatment." The butcher then went on to explain how the dog had bought the best lamb chops in the shop. The man looked at the butcher from the corner of his eye and said, "I don't think he's so intelligent. You see, this is the third time this week he's forgotten his key."Ⅵ.Further Listening and SpeakingTask1:A Birthday PresentMary: David, how did your mom like the dog you gave her for a birthday gift?David: Oh, Mary, she was delighted. It licked her hand and wagged its tail and she was hooked. Mary: What did she call it?David: She's calling it "Brian", after a friend of hers.Mary: Your mom always did have a sense of humor. I read somewhere that dogs can become very close to their owners.David: I've heard that. I saw an interview on TV with a man who had epileptic attacks, and his dog would warn him before he would have an attack.Mary: Really? I wonder how they can do that!David: It has something to do with the dog's sense of smell. It's very keen.Mary: Do you think Brian will be able to foretell when your mom is going to roast a chicken? Task2:100 Percent Polar BearOne afternoon in the Arctic, a father polar bear and his son polar bear were sitting in the snow. The son turned to his father and asked, "Dad, am I 100 percent polar bear?""Of course, son, you're 100 percent polar bear."A few minutes passed, and the bear turned to his father again and said, "Dad, tell me the truth.I can take it. Am I 100 percent polar bear? No brown bear or panda bear?""Son, I'm 100 percent polar bear and your mother is 100 percent polar bear, so you're certainly 100 percent polar bear."A few more minutes passed, and the son polar bear again turned to his father and asked, "Dad, don't worry. But it'll hurt my feelings if it's not true. I really need to know... am I really 100 percent polar bear?"Somewhat angered by this continued questioning, the father polar bear yelled at his son, "Why on earth do you keep asking if you're 100 percent polar bear?""Because I'm freezing to death out here!"Task3:Using Dogs to Sniff out Mold in HomesAre you ready to go to work?" a woman asks her dog Sydney. The dog wags her tail. Then she starts sniffing around inside the house. Sydney is hunting for mold. When she sits down, that means she smells mold nearby. Usually mold is found within three or four feet. A boy who lives in this house has epileptic attacks. It could be from mold. His mother wanted to find the mold. She tried other ways to find it, but they didn't work. She said she trusted the dog more than the other ways. Workers found mold near where Sydney sat. Nobody had thought to look for mold there before. Now it can be cleaned out and the boy will feel much better.Sydney is very special. Only about ten animals in the U.S. can do this. She spent hundreds of hours with a police dog trainer in Florida to learn how. In the U.S., people have used dogs to find drugs and bombs for a long time, but dogs that find mold are something new.People in Europe have used mold-sniffing dogs for many years. Dogs are cheaper to use than human trackers and can find exactly where the mold is. They also do it quickly and for less than $500. Other methods may cost thousands of dollars and take many weeks.。
