Black bears are the smallest of all American bears,ranging in length from five to six feet,weighing from three hundred to five hundred r 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 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 of the most interesting characteristics of bears,including the black bear,is their winter ke squirrels,woodchucks,and many other woodland animals,bears do not actually ough 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.

Ⅱicans And Their Pets
Americans love it’s not just puppy-love (不成熟的愛) pet owners treat their furry friends as part of the times they spice(使增添趣味)up their pets’ lives with entertaining videos and amusing they have an eye for fashion,pet owners can dress their pets in stylish special occasions,they can use canine perfume(狗專用的香水)to make their dogs smell well,less 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 least 43 percent of U.S. homes have pets of some ic(外國產的)creatures,such as monkeys,snakes and even wolves,find a home with some common pets include tropical fish,mice and the all-time favorites are cats and icans sometimes have strong feelings about whether dogs or cats make better pets.“Dog people”and “cat people”often enjoy friendly rivalries(爭辯).
Leading a dog’s life in America isn’t such a bad grocery stores sell pet foods to owners eager to please their Houston,Texas,dogs can have their dinner delivered to their homes,just like -to-do dogs can attend doggy daycare centers while their owners can even accompany their owners on y(豪華的)hotels are beginning to accommodate(接納……住宿)both man and y guests at Four Seasons Hotel can enjoy gourmet(美食) meals served on fine china(精緻瓷器)and sleep in soft beds.
Beneath the luxuries(奢華),there lies a basic American belief:Pets have a right to be treated least 75 animal welfare(福利) organizations exist in e provide care and adoption(領養)services for homeless and abused(受虐待的)rinalians(獸醫)can give animals very good health care-for a high pay for the high-tech health care,people can buy health insurance for their 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 archers have discovered that interacting with animals lowers a person’s blood can offer protection from burglars(竊賊)and unwelcome can help rid the home of unwanted le creature of all shapes and size can provide companionship and even encourage social relationships:They give their owners an appearance of friendliness,and they provide a good topic of conversation.

sample dialogue:
R: Good morning: Mr Tiger. 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.
R: Thank you. Um, would you please take your paw off my shoulder? It hurts.
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.

ening and speaking
1>When farmers cut down trees,tigers no longer hide and hunt.
no longer不再
＜辨析：no longer／no．…any longer／no more／not，…any more
以上四種表達都可以表示“不再”，但用法稍有區別。no longer可寫作not…any longer，no more可寫作not．…any more。一般來講，no longer爲副詞短語，強調時間上的“不再”；而no more可作副詞性短語，也可作形容詞性短語和名詞性短語，它強調程度上的“不再”。有時兩者意義區別不明顯時可替換。經常情況下，no longer位於行爲動詞的前面，位於be動詞的後面。如果不修飾名詞，no more多放在句尾使用。
①I shall go there no more．／I shall no longer go there．我再也不去那了。
②Time lost will return no more．時光一去不復返。
③He no longer works here．／He doesn’t work here any more．／He doesn’t work here any

4>Why is it so important to make sure that animals do not die out?

doing：“阻止、制止……做某事”
①Please keep the children from swimming in the sea．請別讓孩子們到海里游泳。
stop／prevent．…from．…爲keep…．from．…的同義詞組，但前者的from可以省去，而

②His parents stopped him（from）going there他的父母不讓他去那兒。
③Nothing can prevent her（from）doing so．什麼也不能阻止她這樣做。
若表示“阻止做某事”，sth，作動詞的賓語，則from後應跟動名詞的被動語態，即
“阻止某事被做”。如：

其他形容詞來表達不同的意義。如：
①lead／live／have a happy life過着幸福生活
②lead／live／have a quiet life過着平靜的生活
◆harm在這裏作及物動詞，意爲“傷害”；相當於do sb，／sth．harm或do harm to sb．／
sth．。harm也可作名詞。如：
③It will do you no harm．這對你沒有害處。
◆當way表示“方式”方法”在句中作先行詞，後被一個定語從句修飾時，引導定語從句可用that，也可以用in which，或什麼都不用。下列三種說法都是正確的：

ent kful rested rtant
簡析：答案爲A。由句意可知是“所有出席宴會的人都是他的支持者”，故只能選present。當“出席，在場”講時，present作定語放在所修飾詞後。
4.(NMET 2000)-Is John coming by train?
-He should,but he___________ likes driving his car.
簡析：答案爲D。must not意爲“禁止，不許”；need not意爲“不必”；can表推測多用於否定、疑問句中，但can not表“不可能”，與句意不符。只有may not表示“有可能”。
