As ________ as the sky is your mind. As deep as the sea is your kindness.
A．broad B．a(chǎn)board C．a(chǎn)broad D．board
A
【解析】
試題分析：考查詞義辨析。A寬闊（形容詞）；B在船上，在飛機(jī)上，在車上（副詞）；C在國外（副詞）；D板（名詞）；句意：心就像太空一樣寬闊，善良就像海洋一樣深厚。本句中要使用形容詞broad與后面的deep形成呼應(yīng)。故A正確。
考點：考查詞匯辨析
點評：詞匯辨析是每次試卷中必然出現(xiàn)的題型，所以平時一定要把詞匯放在句中進(jìn)行記憶。在復(fù)習(xí)詞匯的時候，要依據(jù)語言的橫向組合和縱向聚合，按照點-線-面順序，構(gòu)建知識網(wǎng)絡(luò)環(huán)境，對知識內(nèi)容進(jìn)行鞏固、深化和提升，這樣才能提高復(fù)習(xí)知識點的效率。這樣，再做單項填空題時，就會覺得游刃有余。對于英語中的詞匯用法，平時要多歸納總結(jié)，詞匯用法的特殊語法規(guī)則更要特別記憶。最好把詞匯放在句子中，連同句子一起記憶，這樣能夠加強(qiáng)記憶。

(A)
Every object tells a story. Even the most ordinary objects can present to us powerful images. Sometimes it is the ordinary nature of these objects that actually makes them so extraordinary. Such is the case with an old leather shoe in a museum in Alaska. At first glance it does not look like much. It is a woman’s shoe of a style popular in the 1890s. But what is unique(獨特的) about this shoe is where it was found. It was discovered on the Checkout Pass, the famous trail used by the people seeking gold in Alaska. Who it belonged to or why it was left there is not known. Was it perhaps dropped by accident as the woman climbed up the 1500 stairs carved outface? Or did she throw away goods that she didn’t need in order to travel lighter?
Over 100, 000 people with “gold fever” made this trip hoping to become millionaires. Few of them understood that on their way they would have to cross a harsh wildness. Unprepared for such a dangerous journey, many died of starvation and exposure to the cold weather.
The Canadian government finally started requiring the gold seekers to bring one ton of supplies with them. This was thought to be enough for a person to survive for one year. They would carry their supplies in backpacks(背包) each weighing up to fifty pounds; it usually took at least 40 trips to get everything to the top and over the pass. Whoever dropped the shoe must have been a brave and determined woman. Perhaps she was successful and made it to Alaska. Perhaps she had to turn back in defeat. No one will ever know for sure, but what we do know is that she took part in one of the greatest adventures in the 19th century.
1. The ordinary woman’s leather shoe is considered unusual because _______.
A. it was an important clue to life in the past B. it was found on a famous trail
C. it at one time belonged to a VIP D. it was a fashionable shoe at that time
2. According to this passage, many people who went to Alaska _______.
A. eventually became millionaires B. brought with them many shoes
C. had conflicts with the Eskimos D. were not properly equipped
3. The Canadian government made gold seekers bring one year’s supplies with them so that _______.
A. they would not die of hunger and cold
B. the army would have enough food for fighting a war
C. they would change these goods with the Eskimos
D. the supplies would make Alaska rich
4. No matter what happened to the woman who owned the shoe, _______.
A. she must have lived a happy life
B. she certainly dropped the shoe on purpose
C. her adventurous spirit is definitely admired
D. her other shoes were equally fashionable
(B)
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(內(nèi)疚)or fear of punishment. “I would rather have someone give me a loving ‘no’ than an obligated(強(qiáng)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, Conneticut. “Most people are afraid of saying ‘no’… My 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’.”
5. The sentence “Saying ‘yes’ to yourself” means _______.
A. you can have more time to play with others
B. you needn’t care about other’s feeling if you are happy
C. you are selfish and treat others rudely
D. you can deal with your business as you have planned
6. When you say “no” to others you should say it in a _______.
A. secret way B. polite way
C. proud way D. guilty way
7. In Watson’s opinion, people can save much time on condition that _______.
A. they say “no” at a suitable time
B. they say “no” as much as possible
C. they are afraid of saying “no”
D. they make others angry at them
8. If a person says “no” to everything, the result he or she receive may be that he or she _______.
A. enjoys a wonderful life B. makes a lot of money
C. faces difficulty in life D. forgets to say “yes” in the end
(C)
A characteristic of American culture that has become almost a tradition is to respect the self-made man — the man who has risen to the top through his own efforts, usually beginning by working with his hands. While the leader in business or industry or the college professor occupies a higher social position and commands greater respect in the community than the common laborer or even the skilled factory worker, he may take pains to point out that his father started life in America as a farmer or laborer of some sort.
This attitude toward manual(體力的) labor is now still seen in many aspects of American life. One is invited to dinner at a home that is not only comfortably but even luxuriously (豪華地) furnished and in which there is every evidence of the fact that the family has been able to afford foreign travel, expensive hobbies, and college education for the children; yet the hostess probably will cook the dinner herself, will serve it herself and will wash dishes afterward, furthermore the dinner will not consist merely of something quickly and easily assembled from contents of various cans and a cake or a pie bought at the nearby bakery. On the contrary, the hostess usually takes pride in careful preparation of special dishes. A professional man may talk about washing the car, digging in his flowerbeds, painting the house. His wife may even help with these things, just as he often helps her with the dishwashing. The son who is away at college may wait on table and wash dishes for his living, or during the summer he may work with a construction gang on a highway in order to pay for his education.
9. From paragraph 1, we can know that in America _________.
A. people tend to have a high opinion of the self-made man
B. people can always rise to the top through their won efforts
C. college professors win great respect from common workers
D. people feel painful to mention their fathers as labors.
10. According to the passage, the hostess cooks dinner herself mainly because _________.
A. servants in American are hard to get
B. she takes pride in what she can do herself
C. she can hardly afford servants
D. It is easy to prepare a meal with canned food
11. The expression “ wait on table” in the second paragraph means “_________”.
A. work in a furniture shop B. keep accounts for a bar
C. wait to lay the table D. serve customers in a restaurant
12. Which of the following may serve as the best title of the passage?
A. A Respectable Self-made Family B. American Attitude toward Manual Labor
C. Characteristics of American Culture D. The Development of Manual Labor

With only about 1, 000 pandas left in the world, China is desperately trying to clone(克隆) the animal and save the endangered species(物種). That’s a move similar to what a Texas A & M University researchers have been undertaking for the past five years in a project called “Noah’s Ark”.
Noah’s Ark is aimed at collecting eggs, embryos(胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & M’s College of Veterinary Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future.
It is estimated that as many as 2, 000 species of mammals, birds reptiles will become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years.
This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal.
The entire procedure could take from three to five years to complete.
“The nuclear transfer(核子移植) of one species to another is not easy, and the lack of available(capable of being used) panda eggs could be a major problem,” Kraemer believes. “They will probably have to do several hundred transfers to result in one pregnancy (having a baby). It takes a long time and it’s difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort,” adds Kraemer, who is one of the leaders of the Project at Texas A& M, the first-ever attempt at cloning a dog.
“They are trying to do something that’s never been done, and this is very similar to our work in Noah’s Ark. We’re both trying to save animals that face extinction. I certainly appreciate their effort and there’s a lot we can learn from what they are attempting to do. It’s a research that is very much needed.”
17. The aim of “Noah’s Ark” project is to _______.
A. make efforts to clone the endangered pandas
B. save endangered animals from dying out
C. collect DNA of endangered animals to study
D. transfer the nuclear of one animal to another
18. According to Professor Kraemer, the major problem in cloning pandas would be the lack of _______.
A. available panda eggs B. host animals
C. qualified researchers D. enough money
19. The best title for the passage may be _______.
A. China’s Success in Pandas Cloning
B. The First Cloned Panda in the World
C. Exploring the Possibility to Clone Pandas
D. China —the Native Place of Pandas Forever
20. From the passage we know that _______.
A. Kraemer and his team have succeeded in cloning a dog
B. scientists try to implant a panda’s egg into a rabbit
C. Kraemer will work with Chinese scientists in clone researches
D. about two thousand of species will probably die out in a century

Scientists have long understood the key role that oceans play in controlling the Earth’s climate. Oceans cover 70 per cent of the surface of the globe and store a thousand times more heat than the atmosphere does. What’s newer is the understanding of how this key component(組成部分) of our climate system responds to global warming.
A brake on global warming—for now
One of the oceans’ most important climate functions is absorbing heat and carbon dioxide(CO2), one of the gases that causes global warming. Acting as something absorbing heat, the oceans have absorbed huge amounts of heat and CO2 in the last forty years.
Fujita explains, “the oceans are saving us from faster climate change—they are putting a brake on the climate system.”
“That’s the good news,” he adds. “The bad news is that the oceans only slow the atmospheric warming. Once the oceans come to balance with a greenhouse-gas warmed earth, the extreme heat will remain in the atmosphere and things will get much hotter.” But where and how the oceans release this slowly increased heat is uncertain. And as the ocean stores heat, fragile(脆弱的) underwater ecosystems are struggling.
The most recent scientific report from the Intergovernmental Panel on Climate Change(IPCC) also notes with concern that the ocean is acidifying(酸化) because of increased absorption of atmospheric CO2. and thus causing a threat to shell-forming species. Sharp increase in CO2 levels will cause further acidification of the ocean.
Currents distributing heat
Another important role the oceans play is that of distributor(散布者). Oceans deliver heat and life-sustaining nutrition around the globe. Just as blood tube bring oxygen and nutrition to cells in the human body, the ocean’s currents carry oxygen, nutrients and heat throughout the Earth. The ocean distributes 25 to 50 per cent of energy the planet receives from the sun. For example, the Gulf Stream carries heat across the Atlantic. This warm current gives northwestern European a milder climate that it would normally have so far north. A change to the ocean’s circulation patterns could throw Europe into a colder period, even as the rest of the world is experiencing warmer temperatures.
【小題1】 We can infer from the passage that _______.
| A．the oceans cause global warming | B．the oceans stop global warming |
| C．the oceans release nutrients and heat | D．the ocean ecosystems face more dangers |
| A．a(chǎn)-c-f | B．a(chǎn)-d-f | C．b-d-e | D．b-c-e |
| A．Asia would suffer a hotter climate. |
| B．Europe would become hotter |
| C．the rest of the world would become warmer. |
| D．the climate of Europe would become colder. |

The man traveling in the back of the ambulance which was running at a high speed along the streets of Baltimore that morning in 2008 had no business to be alive．By everything that was reasonable，and there were plenty of such things before，he should have been very dead indeed．But he wasn’t．As the people in the hospital pointed out after they had examined him，he was only slightly hurt．Yet he had just fallen 150 feet down a hotel lift shaft（電梯通道）!
Unknown to the man，two things had occurred which were to affect his life that day．On the thirteenth f1oor of the hotel, somebody had carelessly left the lift gate open．Down in the basement, a pipe had burst and，it had flooded the bottom of the lift shaft to a depth of two feet．
Modern lifts have all sorts of fail-safe system to prevent accidents，but this was ancient equipment unreliable，slow，dangerous，and suitable material to recycle．
The man had plenty of things to occupy his mind that morning. He had overslept. The hotel had forgotten to call him and now he was late for an important business appointment. He dressed quickly, shaved hurriedly, took hold of his briefcase and hurried off down the hotel corridor.
Good! The life gate was open. The life must be there. He need not press the button and wait while the large, clumsy life made its way upwards. Without looking or thinking, he stepped out into space. The lift cag
e was, in fact, one floor above him on the fourteenth. The would which he had walked was a narrow space of not very fresh sir, ending 150 feet below in two feet of dirty water.
The man fell, making his journey to the ground at a speed he had never dreamed of. Confused patterns, a rush of air, time enough to be afraid, split-second thoughts of death, then-crash!
Perhaps this gave him the record for some sort of high-diving act. No doubt in future he always looked before he jumped. Certainly be learnt that this was no way to save time. The experts said that those two feet of water had saved his life.
59．What do we learn about the man?
A．He fell from the 13th floor. B．He was hit by an ambulance．
C．He got caught in a serious flood． D．He made a record for high-diving.
60．By “……h(huán)ad no business to be alive”，the writer means that the man_______.
A．had missed his business appointment B．was alive with excitement
C．was alive and this was surprising D．didn’t do any business
61．Tile lift did not have a fail-safe system because it was____________.
A．narrow B．slow C．1arge D．old
62．Which of the following was NOT the cause of the accident?

I ran across an old photo of him the other day, thinking of some old things. He’s been dead for 25 years. His name was Rex.

I suppose he would have held his own 52 dawn if we hadn’t helped him. The next day we carried the box miles away and threw it out. If we had thrown it out in a 53 place, he would have brought it home again, as a small token(象征)of his strength in such matters. 54, he had been taught to carry heavy wooden objects about and he was 55 of his skill.

Last week I saw the release of the second part, and boy oh boy does it shows. But watching the film as a foreigner I felt I was missing out on something. Not knowing my Cao Cao's from my Zhou Yu's, I was not even sure whom I wanted to win. Certainly after the opening scene, in which Cao Cao is seen watching a game of Cuju, an ancient Chinese variation of football, I knew who had my support. After all, any man who enjoys his football is someone after my own heart. But after Cao Cao resorted to some evil strategies against his enemies in the south, I wasn't so sure he was the man I should be rooting for. And there is a lot more to Red Cliff 2 than just extravagant battle scenes. The film does not take itself too seriously. Conversations between leaders are littered with one-liners, many of which had the audience in laughter. There is even enough to keep fans of more romantic entertainment happy too. This includes a charming relationship between a southern spy（偵探）and an innocent northern soldier. The characters' interaction provides some genuinely heart-warming moments in the middle of the battle. Clocking in at（結(jié)束于）around two hours, the film certainly does justice to the history story. When I walked out the cinema, I felt as drained（精疲力竭） as Cao Cao's soldiers must have 1,800 years ago. 41.By expressing “boy oh boy” in the first paragraph, the author seems to show that _______.
42.When did the author change his attitude toward Cao Cao?

Its look and feel are only slightly improved, but a faster network loads Web pages more quickly, true GPS functionality allows it to easily find places nearby, and the new $199 price (down from $400) makes it an affordable luxury. Before deciding whether to buy, however, make sure you can actually take advantage of the iPhone 3G's high-speed data network. 3G stands for third-generation, which in non-geek speak translates to Web pages and mail messages that, ideally, load about three times faster than on the original iPhone. Even better, 3G coverage enables you to make a phone call and surf the Web at the same time. That's great, if you live or work in a place where the 3G network of AT&T（美國電話電報公司） (the sole wireless carrier of the iPhone) is active. That's not so great in cities like New York where AT&T's cellular coverage is awful. As one of my colleagues in New York City, who bought the original iPhone, commented, "It's just a toy. You can't make phone calls on it, so I carry my Verizon phone with me all the time." The real fun begins when you tap on the icon called "App Store" and start browsing the hundreds of add-on applications that have been developed just for the iPhone. You'll find tons of games (I like JirboBreak, a free game inspired by the Atari classic Breakout) and mobile versions of popular websites like Pandora, Facebook, MySpace and the New York Times. Most apps will cost you, but the vast majority are $9.99 or less. The apps work on the old iPhones too, but you'll enjoy them a lot more on the iPhone 3G because many of the programs, including Yelp (local business reviews), Whrrl (mobile social networking) and UrbanSpoon (restaurant reviews), use your exact location — provided by the iPhone 3G's GPS chip — to make recommendations. The apps also load much faster over the 3G network. 57.The new iPhone 3G has following features except that _______

Earlier studies have documented half-brain sleep in a wide range of birds. The brain hemispheres take turns sinking into the sleep stage characterized by slow brain waves. The eye controlled by the sleeping hemisphere keeps shut, while the wakeful hemisphere’s eye stays open and alert. Birds also can sleep with both hemispheres resting at once. Decades of studies of bird groups led researchers to predict extra alertness in the end-of-the-row sleepers which tend to be attacked more easily. Sure enough, the end birds tended to watch carefully on the side away from their companions. Ducks in the inner spots showed no preference for gaze direction. Also, birds napping at the end of the line depend on single-hemisphere sleep, rather than total relaxation, more often than inner ducks did. Turning 16 birds through the positions in a four-duck row, the researchers found that compared with 12 percent for birds in internal spots, outer birds half-asleep during some 32 percent of napping time. “We believe this is the first evidence for an animal behaviorally controlling sleep and wakefulness at the same time in different regions of the brain,” the researchers say. The results provide the best evidence for a long-standing assumption that single-hemisphere sleep evolved as creatures scanned for enemies. The preference for opening an eye on the lookout side could be widespread, he predicts. He’s seen it in a pair of birds napping side-by-side in the zoo and in a single pet bird sleeping by a mirror. The mirror-side eye closed as if the reflection were a companion and the other eye stayed open. Useful as half-sleeping might be, it’s only been found in birds and such water animals as dolphins, whales, and seals. Perhaps keeping one side of the brain awake allows a sleeping animal to surface occasionally to avoid drowning. Studies of birds may offer unique insights into sleep. Jerome M. Siegel of the UCLA says he wonders if birds’ half-brain sleep “is just the tip of the iceberg.” He supposes that more examples may turn up when we take a closer look at other species. 65.According to the passage, birds often half sleep because ______.
66.What is implied about the example of a bird’s sleeping in front of a mirror?
67. While sleeping, some water animals tend to keep half awake in order to ______.
68.By saying “just the tip of the iceberg”, Siegel suggests that ______.

As Sam Beattie reports from Beijing, there is widespread hope for closer U.S.-Chinese cooperation. For many students in Beijing, Mr. Obama symbolizes all that is possible in the United States. He's a popular winner here, seen as a self-made man who has made it to the top. "I think he is very charming, and a president who can create a new era," said Zhang Wei, a university student. "I like him very much and most of my friends do too." Ni Weibo, another university student, agrees. "Sino-U.S. relations still need more cooperation," she said. "I think he will help take it to a new era." China's President Hu Jintao congratulated Mr. Obama within hours of his victory, saying he hoped bilateral ties could be made stronger. Political analysts here say China will be looking for the incoming president to avoid contentious issues such as Taiwan's independence, human rights and Tibet. Instead, they say Beijing would like Mr. Obama to focus on solving the global economic crisis, and to help China's slowing economy by opening up U.S. markets. But trade relations might be a sticking point, says Renmin University's Professor of International Studies, Shi Yinhong. He warns, "There is a possibility that President Obama will take some protectionist measures which China will not accept, then trade disputes could develop to a degree that we have not seen ever before." Despite making the headlines, Mr. Obama faces some tough challenges in managing the U.S. relationship with China. China is now a stronger and more confident country than the China his predecessors dealt with. And in this time of economic uncertainty, analysts say it's a country with which Mr. Obama will want to maintain a good relationship. 73.What can we infer from the first three paragraphs?
74.What is not mentioned in this passage?
75. What does “ a sticking point”( in para.7 ) mean?
76.What is the best title for this report?
