题目列表(包括答案和解析)
Most people regard zoos as safe places for animals, where struggles such as difficulty finding food and avoiding predators（捕食性动物） don't exist. Without such problems, animals in zoos should live to a ripe old age. But that may not be true for the largest land animals on Earth. Scientists have known that elephants in zoos often develop diseases, joint problems and behavior changes. Sometimes, they even become unable to have babies.
To learn more about how captivity(监禁) affects elephants, a team of international scientists led by Mason, a biologist, compared the life spans of female elephants born in zoos with female elephants living outdoors in the wild. Zoos keep detailed records of all the animals in their care, documenting factors such as birth dates, illnesses, weight and death. These records made it possible for the researchers to analyze 40 years of data on 800 elephants in zoos.
The team found that female elephants born in zoos lived an average of 16.9 years. Their wild counterparts（同类事物） who died of natural causes lived an average of 56 years——more than three times as long.
Scientists don't yet know for sure why wild elephants seem to live so much better than their zoo-raised counterparts. Mason thinks stress and obesity(肥胖) may be to blame. Zoo elephants don't get the same kind of exercise as they do in the wild, and most are very fat. Elephant social lives are also much different in zoos than in the wild, where they live in large groups.
Another finding from the study showed that elephants born in zoos were more likely to die earlier than elephants captured in the wild and brought to zoos. Mason suggests stress in the mothers in zoos might cause them to have babies that are less likely to survive.
The study raises some questions about acquiring more elephants to keep in zoos. While some threatened and endangered species living in zoos reproduce successfully and keep healthy populations, that doesn't appear to be the case with elephants.

Listen carefully, working people, we would like to tell you something that could save your precious time and money! Best of all, it is free!
It’s “no”.
What do you ask? We’ll say it again: “No”.
Sweet and simple “no”.
Say “no” at your office and see how quickly that pile of work on your desk disappears.
“Saying ‘no’ to others means you are saying ‘yes’ to yourself, ” said Leslie Charles, a professional speaker from East Lansing, Michigan.
“Time is precious. People are spending money buying time. And yet we are willing to give up our time because we can’t say ‘no’.”
Susie Watson, a famous writer, said people who always say “yes” need to say “no” without guilt(内疚)or fear of punishment. “I would rather have someone give me a loving ‘no’ than an obligated(强制的) ‘yes’, ” she said.
Susie Watson says she feels “no” obligation to give an explanation when she says “no” either socially or professionally. Does she feel guilty about it? “Not at all, ” said Watson, who is director of advertising and public relations at Timex Corp in Middlebury, Connecticut. “Most people are afraid of saying ‘no’advice is to say ‘yes’ only if you don’t mean ‘no’.” Watson said “no” is the most effective weapon against wasting time. “Every year there are more demands on your time… Other people are happy to use up your time, ” Watson said. Time saving appears to be “no’s” greatest friend.
“No” can be your new friend, a powerful tool to take back your life. “No” may even take you further in the business world than “yes”.
“No” is power and strength. “No” now seems completely correct. “Saying ‘no’ isn’t easy. But finally it’s greatly liberating,” Charles said. But, he added, a “no” project needs to be worked on every day because it is hard to change long-term habit.
But, he also warns: “Don’t go to extremes. Don’t find yourself saying ‘no’ to everything. In return you should learn to hear ‘no’.”

A friend in need
Brownie and Spotty were neighbor dogs who met every day to play together. Like pairs of dogs you 36 find in any neighborhood, these two 37 each other and played together so often that they had worn a path through the grass of the field between their own houses.
One evening, Brownie's family 38 that Brownie hadn't returned home. They went looking for him with no 39 Brownie didn't appear the next day, and despite(尽管)their 40 to find him, by the next week he was still missing. Curiously, Spotty 41 at Brownie's house alone, barking. Busy with their own lives, Brownie's family just ignored the 42 little neighbor dog. Finally, one morning Spotty 43 to take “no” for an answer any longer. He followed Ted about, barking strongly, then running towards a nearby wood, as if to say," 44 me! It’s urgent!”
Then Ted followed the anxious Spotty. The little dog led the man to a 45 spot a half mile from the house.

Spotty had obviously 53 with Brownie to protect him from being hurt, snuggling(依偎)with him at night to keep him warm and touching him gently with its nose to keep his 54 up. Brownie's leg was treated by a veterinarian and he recovered. For many years afterward, the two 55 watched the faithful friends frolicking(嬉戏)and chasing each other down that well worn path between their houses.

What do college teachers think of high school English teachers’English teaching? And how should we see it? Let’s read the following.
A teacher from a community college addressed a sympathetic audience. Heads nodded in agreement when he said, “High school English teachers are not doing their jobs.” He described how weak his students were—all high school graduates who can use language only at a Grade 9 level.
My topic is not standards nor its decline（降低）. What the speaker was really saying is that he is no longer young; he has been teaching for sixteen years, and is able to think and speak like a mature adult.
My point is that the frequent complaint of one generation about the one immediately following is natural. It is also human nature to look for the reasons for our dissatisfaction. Before English became a school subject in the late nineteenth century, it was difficult to find the target of the blame for language deficiencies（缺陷）. But since then, English teachers have been under constant attack.
The complainers think they have hit upon an original idea. As their own command of the language improves, they notice that young people do not have this same ability. Unaware that their own ability has developed through the years, they assume the new generation of young people must be hopeless in this respect. To the eyes and ears of sensitive adults, the language of the young always seems inadequate.
Since this concern about the decline and fall of the English language is not seen as a generational phenomenon but rather as something new and peculiar(特有的) to today’s young people, it naturally follows that today’s English teachers cannot be doing their jobs.
1.The speaker believed that ________.
A. he was an excellent language teacher because he had been teaching English for sixteen years
B. the younger generation was as likely as not worse at language than the older generation
C. high school English teachers should be responsible for their students’ poor command of English
D. The fact that the students didn’t work hard enough contributed to their poor command of English
2. In the author’s opinion, the speaker ________.
A. had exaggerated (夸大) the language problems of the students
B. was right in saying English teachers were not doing their jobs
C. gave a correct judgment of the English level of the students
D. thought and spoke in a wise and responsible way
3.What can we conclude from the passage?
A. Language learning and improving needs time and effort.
B. The author disagrees with the speaker over the standard of English at Grade 9 level.
C. It is reasonable to include English as one of the high school subjects.
D. The English language teaching is by no means an easy job for college teachers.
4.The author’s attitude towards the speaker’s remarks is ________.
A. neutral（中立的） B. critical
C. positive D. compromising(妥协的)
A famous American John Muir said in 1898: “The Grand Canyon… as unearthly (神秘的) in the color and grandeur (壮观) of its architecture as if you had found it after death on some other star.” Like Muir, those of us who stand along the rim are prompted to wonder about the unearthliness and the forces that created and are still changing this place.
After more than 100 years of studies, many things are still mysterious. Today visitors come by the thousands -- the great and simple of the earth -- all in a spirit of wonder. Travelers come from every state of the Union, from every country in Europe and Asia.
From the depths of the canyon comes welling silence. Seldom can you hear the roar of the river, for all sounds are swallowed in this gulf of space. “It makes one want to murmur.” A woman once whispered to her companion. This silence is not the silence of death; rather, it is a presence. It is like a great piece of music. But music made of man works up to a climax (高潮) and stops.
Now, visitors to the South Rim alone may number 18,000 in a single day. Some of that number will travel by mule train down Bright Angel Trail to the canyon's floor, cross the raging river by a suspension bridge (吊桥) and walk to the North Rim. Though the two rims face each other across only 12 miles, it is a journey of 214 miles by car from one to the other. Nor can you visit the North Rim except in summer; some 1,200 feet higher than the South Rim, it is snow covered much of the year except in July and August.
But there is no day that you may not visit the South Rim and find the sun warm on your face and the air perfumed with the incense (香气) of smoke from an Indian hearth (香炉). No wonder an American writer and journalist said, “I came here an atheist (无神论者), and departed a devout （虔诚的）believer.”
What is it that attracts so many travelers to the Canyon?
A. The unearthliness and the grandeur of its architecture.
B. The presence of American super stars.
C. The saying made by American writers and journalists.
D. The roaring of the river in the Canyon.www..ocm
What does the underlined word “simple” refer to?
A. peaceful stream B. land surface C. common people D. tamed animals
If you want to visit the North Rim from the South Rim, which of the following won’t be the way of traveling for you?
A. By train. B. By animal. C. By car. D. On foot.
The last sentence “I came here an atheist, and departed a devout believer.” implies that ______.
A. natural wonders such as the Canyon have some effect on human activities
B. all visitors to the Grand Canyon are God believers
C. atheist can’t see the magnificence of the Grand Canyon
D. the Grand Canyon is an unearthly sight that only God could create
