American Black BearsAmerican 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,

26、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（一胎所生的小動(dòng)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,

27、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（膽小的）, clumsy（笨拙的）and rarely dangerous, but if attacked, most can climb trees and cover ground at great spe

28、eds. 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

29、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）seas

30、on. They prefer to live in caves, hollow logs, or dense thickets（灌木叢）. A litter of one to four cubs is born in January or February after a gestation（懷孕）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 a

31、s long as thirty years in the wild, and even longer in preserves（禁獵地） set aside for them. . Americans And Their PetsAmericans love pets. And its not just puppy-love （不成熟的愛）. 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 entertain

32、ing 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（狗專用的香水）to make their dogs smell well, less beastly. You might say Americans treat their pets like they treat their childrensometimes ev

33、en 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（外國(guó)產(chǎn)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

34、 the all-time favorites are cats and dogs. Americans sometimeshave strong feelings about whether dogs or cats make better pets. “Dog people”and “cat people”often enjoy friendly rivalries（爭(zhēng)辯）. Leading a dogs life in America isnt such a bad thing. Many grocery stores sell pet foods to owners eager to

35、please their pets. In Houston, Texas, dogs can have their dinner delivered to their homes, just like pizza. Well-to-do dogs can attend doggy daycare centers while their owners work. Pets can even accompany their owners on vacation. Fancy（豪華的）hotels are beginning to accommodate（接納住宿）both man and beas

36、t. Furry guests at Four Seasons Hotel can enjoy gourmet（美食） meals served on fine china（精致瓷器）and sleep in soft beds. Beneath the luxuries（奢華）, 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 an

37、d adoption（領(lǐng)養(yǎng)）services for homeless and abused（受虐待的）animals. Veterinalians（獸醫(yī)）can give animals very good health carefor a high price. To pay for the high-tech health care, people can buy health insurance for their pets. And when its time to say good-bye, owners can bury their pets in a respectable p

38、et cemetery（墓地）. The average American enjoys having pets around, and for good reason. Researchers have discovered that interacting with animals lowers a persons blood pressure. Dogs can offer protection from burglars（竊賊）and unwelcome visitors. Cats can help rid the home of unwanted pet. Little creat

39、ure of all shapesand 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

40、 property, but a part of the family.  二、知識(shí)歸納（一）make sure用法歸納本短語意為“務(wù)必使，務(wù)請(qǐng)；查明，弄清楚”, 其用法有幾點(diǎn)值得注意。（1）后接that從句，從句要用一般現(xiàn)在時(shí)表示將來時(shí)。e. g.
