Reference for Teaching 一、异域风情 Ⅰ.American Black Bears American black bears appear in a variety of colors despite their name.In the eastern part of their range,most of these bears have shiny black fur,but in the west they grow brown,red,or even yellow coats.To the north,the black bear is actually gray or white in color.Even in the same litter(一胎所生的小动物),both brown and black furred bears may be born. Black bears are the smallest of all American bears,ranging in length from five to six feet,weighing from three hundred to five hundred pounds.Their eyes and ears are small and their eyesight and hearing are not as good as their sense of smell. Like all bears,the black bear is timid(胆小的),clumsy(笨拙的)and rarely dangerous,but if attacked,most can climb trees and cover ground at great speeds.When angry or frightened,it is a formidable(可怕的)enemy. Black bears feed on leaves,herbs,roots,fruit,berries,insects,fish and even larger animals.One of the most interesting characteristics of bears,including the black bear,is their winter sleep.Unlike squirrels,woodchucks,and many other woodland animals,bears do not actually hibernate.Although the bear does not eat during the winter months,sustaining itself from body fat,its temperature remains almost normal,and it breathes regularly four or five times per minute. Most black bears live alone,except during mating(交配)season.They prefer to live in caves,hollow logs,or dense thickets(灌木丛).A litter of one to four cubs is born in January or February after a gestation(怀孕)period of six to nine months,and they remain with their mother until they are fully grown or about one and a half years old.Black bears can live as long as thirty years in the wild,and even longer in preserves(禁猎地) set aside for them. Ⅱ.Americans And Their Pets Americans love pets.And it’s not just puppy-love (不成熟的爱).Many pet owners treat their furry friends as part of the family.Sometimes they spice(使增添趣味)up their pets’ lives with entertaining videos and amusing toys.If they have an eye for fashion,pet owners can dress their pets in stylish clothes.For special occasions,they can use canine perfume(狗专用的香水)to make their dogs smell well,less beastly.You might say Americans treat their pets like they treat their children—sometimes even better. In America,there are more households with pets than those with children.At least 43 percent of U.S. homes have pets of some sort.Exotic(外国产的)creatures,such as monkeys,snakes and even wolves,find a home with some Americans.More common pets include tropical fish,mice and birds.But the all-time favorites are cats and dogs.Americans sometimes have strong feelings about whether dogs or cats make better pets.“Dog people”and “cat people”often enjoy friendly rivalries(争辩). Beneath the luxuries(奢华),there lies a basic American belief:Pets have a right to be treated well.At least 75 animal welfare(福利) organizations exist in America.These provide care and adoption(领养)services for homeless and abused(受虐待的)animals.Veterinalians(兽医)can give animals very good health care—for a high price.To pay for the high-tech health care,people can buy health insurance for their pets.And when it’s time to say good-bye,owners can bury their pets in a respectable pet cemetery(墓地). The average American enjoys having pets around,and for good reason.Researchers have discovered that interacting with animals lowers a person’s blood pressure.Dogs can offer protection from burglars(窃贼)and unwelcome visitors.Cats can help rid the home of unwanted pet.Little creature of all shapes and size can provide companionship and love.Pets even encourage social relationships:They give their owners an appearance of friendliness,and they provide a good topic of conversation. Pets are as basic to American culture as hot dogs or apple pie.To Americans,pets are not just property,but a part of the family. speaking 1．关于保护环境的建议的表达。 First of all. we need to,..

My name is Jim and I'm a reporter from China Daily. Uh, I am a little nervous, this is the first time I speak to a tiger. May I ask you some questions? T: Sure. And don't be nervous, I won't eat you. Ha ha! R: Urn, right, good... Now, how long have you been living in the zoo? T: Oh, I came here, let me see, six years ago. I used to live in a forest, but people there cut down all the trees and I had to move. There were cities and people everywhere, so I had no place to go. The police came and took me to the zoo. R: Do you like living in the zoo? T: Well, it's not as good as being free, that's for sure. But at least I have food and friends. R: I see. If you could say something to all the humans in the world, what would you tell them? T: I would tell them to stop being so selfish. We all need each other and we should try to be friends. If people cut down trees and pollute the environment to make money, we will all suffer. And don't kill animals to make clothes -- when ! see people wearing animal furs at the zoo I get really angry. T: I'm sorry. I guess I got a bit excited. Don't get me wrong. I like humans. I just wish they would be less selfish. R: Thank you, Mr Tiger. reading 整体阅读 1.In what way nature seems to be cleverer than human beings? A. It does not think. B. It is a better recycler. C. It always stays calm. D.

A.either B.neither C.some D.any 简析：答案为B。前句提到Monday or Tuesday,意为在两者之中选择，故可排除C、D两项。后文用I’m afraid…来回答，显然是否定含义，故选neither，意为两天都不可能。 3.(2002 北京)All the people___________at the party were his supporters. A.present B.thankful C.interested D.important 简析：答案为A。由句意可知是“所有出席宴会的人都是他的支持者”，故只能选present。当“出席，在场”讲时，present作定语放在所修饰词后。 4.(NMET 2000)—Is John coming by train? —He should,but he___________not.He likes driving his car. A.must B.can C.need D.may 简析：答案为D。must not意为“禁止，不许”；need not意为“不必”；can表推测多用于否定、疑问句中，但can not表“不可能”，与句意不符。只有may not表示“有可能”。 |
