Our boat floated on between walls of forest. It was too thick for us to get a view of the land we were passing through, though we knew from the map that our river must be passing through chains of hills from time to time. Nowhere did we find a place where we could have landed: although the jungle did not actually spread right down into the river, banks of soft mud prevented us from going ashore. In any case, what would we have gained by landing? The country was full of snakes and other dangerous creatures and the jungle was so thick that one would be able to advance slowly, cutting one's way with knives the whole way. So we stayed in the boat, hoping that when we reached the sea, a friendly fisherman would pick us up and take us to civilization.

As for water, there was a choice. We could drink the muddy river water, or die of thirst. We drank the water. Men who have just escaped from what appeared to be certain death lost all worries about such small things as diseases caused by dirty water. In fact, none of us suffered from any illness as a result.

One day we passed another village, but fortunately nobody saw us. We did not wish to risk being taken prisoners a second time: we might not be so lucky as to escape in a stolen boat again.

1.What they could see on the boat was only___ .

A. high walls         B. chains of hills  C. heavy woods D. vast land

2.They couldn't land because_______ .

A. the mud on the shore was too soft      B. they could not find anyone

C. they could not find the mark on the map D. the forest was too thick to go through

3.From the passage, we can learn that_____ .

A. they were in an uninhabited area       B. they were on a journey home happily

C. the country was a civilized society    D. the country was a tropical jungle coutry

4.The best title for this passage might he______

A. I he Problem of Landing                B. Escape in the Jungle

18【题文】If you travel to a new exhibition at the San Francisco Conservatory of Flowers, you will have chances to see some meat-eating plants. Take bladderworts, a kind of such plant, for example. They appear so small and grow in a quiet pond. "But these are the fastest known killers of the plant kingdom, able to capture a small insect in 1/50 of a second using a trap door!"

Once the trap door closes on the victim, the enzymes (酶)similar to those in the human stomach slowly digest the insert. When dinner is over, the plant opens the trap door and is ready to trap again.

Meat-eating plants grow mostly in wet areas with soil that doesn't offer much food nutrition. In such conditions, these amazing plants have developed insect traps to get their nutritional needs over thousands of years. North America has more such plants than any other continents.

Generally speaking, the traps may have attractive appearance to fool the eye, like pitcher plants, which get their name because they look like beautiful pitchers full of nectar (花蜜).

Hair-like growths along the pitcher walls ensure that nothing can escape, and the digestive enzymes can get to work. A tiny insect can be digested in a few hours, but a fly takes a couple of days.

Some of these pitchers are large enough to hold 7.5 liters. Meat-eating plants only eat people in science fiction movies, but sometimes a bird or other small animals will discover that a pitcher plant isn't a good place to get a drink.

9.From Paragraph 1,we learn that bladderworts can__ .

A. kill an insect in a second         B. digest a fly in a few hours

C. be found floating on a quiet lake  D. capture an insect in 1/50 of a second

10.If the trap door of a meat-eating plant is closed, the plant is

A. fooling insects into taking a sip  B. producing nectar

C. tempting insects to come close     D. enjoying a dinner

11.Meat-eating plants can grow in wet and poor soil because they    .

A. can get nutrition from animals     B. don't need much food nutrition

C. can make the most of such conditions    D. have developed digestive enzymes

12.What can be captured by meat-eating plants for food?

A. A child. B. A dog.   C. A little bird.   D. A little fish.

20【题文】BUKHANNON, West Virginia~~Two rescue teams slowly moved along a two—mile path on Monday night to the site of a coal mine explosion that trapped 13 miners, who had not been heard from since the early morning accident.

Meanwhile, at a nearby church, more than 250 family members and friends gathered, waiting for updates on the rescuers' progress.

The miners were trapped at about .6:30 and many families weren't informed of the accident until about 10 a.m.~~more than three hours after it happened. "It's very upsetting, but you've got to be patient, I guess," said John Helms, whose brother, Terry, was trapped in the mine.

The trapped miners were about 260 fee underground and about 10,000 feet from the Sago Mine's entrance, said Roger Nicholson, a lawyer from International Coal Group.

At a late night news conference, Nicholson said one team had advanced about 4, 800 feet in the four hours since entering the mine just before 6 p.m. Another team entered the mine about 30 minutes later.

He said the crew was very experienced, with some members having worked underground for 30 to 35 years. The miners were equipped with al>out one hour of breathable oxygen each. The company has not released the names of the miners.

The teams test the air about every 500 feet, and have to disconnect the power to the phones they use to communicate with the surface before doing that. "We don't want to be electrifying anything if it's in an atmospfiere with hurnahle gases," Kips said.

The cause of the explosion was not immediately known. High levels of carbon monoxide ( 一氧化物) were discovered shortly after the explosion, which delayed rescue efforts, but those levels have weakened since then, authorities said.

25.According to the passage, we ran infer that_ .

I.     communication with the trapped miners was cut off

J.    the rescue started as soon as the accident happened

K.  the two rescue teams entered the mine at the same time

L.   all the miners who were trapped underground were still alive

26.If the first team advanced at an average speed, they could dig about______per hour.

A. 1,000 feet         B. 1,200 feet       C. 2,400 feet       D. 4,800 feet

27.Where ran the passage he seen?

A. Iii a magazine.    B. In a science hook. C. On an advertisement. D. In a newspaper.

21【题文】

You wake up in the morning, the day is beautiful and the plans for the day are what you have been looking forward to for a long time. Then the telephone rings, you say hello, and the drama starts. The person on tbe other end has a depressing tone in his voice as he starts to tell you how terrible his morning is and that there is nothing to look forward to. Are you still in a wonderful mood? Impossible!

Communieating with negative people can wash out your happiness. It may not change what you think, but communicating long enough with them will make you feel depressed for a moment or a long time.

Life brings ups and downs, but some people are stuck in the wrong idea that life has no happiness to offer. They only feel glad when they make others feel bad. No wonder they can hardly win others' pity or respect.

When you communicate with positive people, your spirit stays happy and therefore more positive things are attracted. When the knife of a negative person is put in you, you have the heavy feeling that, all in all, brings you down.

Sometimes we have no choice but to communicate with negative people. This could be a co-worker, or a relative. In this case, say what needs to be said as little as possible. Sometimes it feels good to let out your anger back to the negative person, but this is to lower you to that same negative level and they won't feel ashamed of themselves about that.

Negativity often affects happiness without even being realized. The negative words of others at the start of the day can be attached to you throughout the rest of your day, which makes you feel bad and steals your happiness. Life is too short to feel negative. Stay positive and avoid negativity as much as possible.

31. Which of the following shows the position where the miners were trapped? (E: entrance P: position where the miners were trapped)

32.The purpose of Paragraph 1 is to____ .

A. make a comparison                  B. introduce a topic

C. offer an instructive story         D. tell a true story

33.How can negative people have effect on us?

A. By influencing our emotion.        B. By telling us the nature of life.

C. By changing our way of thinking.   D. By comparing their attitude to life with ours.

34.Some negative people base their happiness on —.

A. their pity for other people        B. their respect for others '

C. building up a positive attitude    D. making other people unhappy 35.According to the passage, to reduce negative people's influence on us, we are advised.

A.  to change negative people's attitude to life

B.  to show our dissatisfaction to negative people

C.  to make negative people feel as hamed of themselves

D.  to communicate with negative people as little as possible

(2011·安徽卷)B

Think about the different ways that people use the wind. You can use it to fly a kite or to sail a boat. Wind is one of our cleanest and richest power sources(来源), as well as one of the oldest. Evidence shows that windmills(风车)began to be used in ancient Iran back in the seventh century BC. They were first introduced to Europe during the 1100s, when armies returned from the Middle East with knowledge of using wind power.

For many centuries, people used windmills to grind(磨碎)wheat into flour or pump water from deep underground. When electricity was discovered in the late 1800s, people living in remote areas began to use them to produce electricity. This allowed them to have electric lights and radio. However, by the 1940s, when electricity was available to people in almost all areas of the United States, windmills were rarely used.

During the 1970s, people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity. People also realized that the supply of coal and gas would not last forever. Then, wind was rediscovered, though it means higher costs. Today, there is a global movement to supply more and more of our electricity through the use of wind.

60. From the text we know that windmills              .

A. were invented by European armies

B. have a history of more than 2800 years

C. used to supply power to radio in remote areas

D. have rarely been used since electricity was discovered

61. What was a new use for wind power in the late l9th century?

A. Sailing a boat. 

B. Producing electricity.

C. Grinding wheat into flour.

D. Pumping water from underground.

62. One of the reasons wind was rediscovered in the 1970s is that             .

A. wind power is cleaner

B. it is one of the oldest power sources

C. it was cheaper to create energy from wind

D. the supply of coal and gas failed to meet needs

63. What would the author probably discuss in the paragraph that follows?

A. The advantage of wind power.

B. The design of wind power plants.

C. The worldwide movement to save energy.

D. The global trend towards producing power from wind.

【解析】选D。推理判断题。根据末段句子Today, there is a global movement to supply more and more of our electricity through the use of wind可知,接下来作者应该谈论利用风能发电的情况,因此选择D项。

11【题文】  With its budget of $80 million , John Woo as director, and an all-star cast(明星云集的演员阵容), Red Cliff is the most expensive and ambitious Asian-financed film ever. 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(侦探)and an innocent northern soldier. The characters' interaction provides some genuinely heart-warming moments in the middle of the battle.

Clocking in at(结束于)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 _______.

A.the film characters are like boys who are childish.

B.the film provides amazing and surprising scenes for audience.

C.the film is suitable for younger boys to watch.

D.the film scene is so bloody that boys shouldn’t watch it.

42.When did the author change his attitude toward Cao Cao?

A.When he read the history story about Cao Cao.

B.When he saw Cao Cao was watching a game of Cuju,

C.When he realized that Cao Cao took some bad measures to beat his enemies.

D.When he saw the romantic love story of Cao Cao and a southern spy.

43.The following factors of the film are all mentioned in the passage except_______.

A.high budget

B.leading roles

C.actors and actress

D.conversations

44.From the passage we can infer that_______.

A.the author is a football fan in a foreign country.

B.Cuju is the name of an ancient Chinese variation of football.

C.the film Red Cliff 2 lasts about two hours.

D.the author was very tired after about two hours’ battle.

13【题文】The new iPhone 3G should please everyone. 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(美国电话电报公司) (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 _______

A.It looks and feels better

B.It has a faster network

C.It is easy to locate a place

D.It is too expensive for people to buy

58.Why do one of my colleagues carry Verizon phone with him all the time? ______.

A.Because iPhone 3G is just a toy.

B.ecause he prefers Verizon phone better.

C.Because AT&T's cellular coverage is terrible there

D.Because Verizon phone enables him make a phone call and surf the Web at the same time

59.Which of the following statements is NOT true according to the passage. ____.

A.App Store will offer you great fun.

B.many apps have been developed for the iPhone.

C.Most apps are very expensive.

D.Pandora, Facebook, MySpace and the New York Times are popular websites.

60.From the passage we know that the attitude of the author toward iPhone 3G is _____.

A.doubtful

B.appreciative

C.optimistic

D.pessimistic

14【题文】Birds that are half-asleep—with one brain hemisphere (半球) alert and the other sleeping—control which side of the brain remains awake, according to a new study of sleeping ducks.

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 ______.

A.they have to watch out for possible attacks

B.their brain hemispheres take turns to rest

C.the two halves of their brain are differently structured

D.they have to constantly keep an eye on their companions

66.What is implied about the example of a bird’s sleeping in front of a mirror?

A.An imagined companion gives the bird a sense of security.

B.Birds prefer to sleep in pairs for the sake of their security.

C.The phenomenon of birds napping in pairs is widespread.

D.A single pet bird enjoys seeing its own reflection in the mirror.

67. While sleeping, some water animals tend to keep half awake in order to ______.

A.alert themselves to the approaching enemy

B.emerge from water now and then to breathe

C.be sensitive to the ever-changing environment

D.avoid being swept away by rapid currents

68.By saying “just the tip of the iceberg”, Siegel suggests that ______.

A.half-brain sleep has something to do with icy weather

B.the mystery of half-brain sleep is close to being solved

C.most birds living in cold regions tend to be half sleepers

D.half-brain sleep may exist among other species

15【题文】People in China, as in other parts of the world, are waiting to see how U.S. President-elect Barack Obama will deal with global problems such as the current economic slowdown once he takes office. 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?

A.Mr. Obama was popular with many students in Beijing mostly because he will take office soon.

B.Economic slowdown is the big problem that the world is facing and looking forward to solve except US

C.China’s President Hu Jintao congratulated Obama on his victory within hours.

D.Through Obama’s being elected, we can see all is possible in US and a new relationship may come.

74.What is not mentioned in this passage?

A.What Barack Obama is expected to do in dealing with the US-China relationship.

B.Why Barack Obama will maintain a good relationship with China.

C.How Barack Obama will deal with the current economic slowdown.

D.What image Barack Obama has given to Chinese people.

75. What does “ a sticking point”( in para.7 ) mean?

A.a twist point

B.a disputed point

C.a good beginning

D.a understanding point

76.What is the best title for this report?

A.US-Chinese Cooperation Under the Current Economic Slowdown

B.Obama, Seen As A Popular Winner In China

C.Chinese Want Stronger Ties With US Under Obama Administration

D.The Current Economic Problem faces China As Well As US

People use their mouths for many things. They eat, talk, shout and sing. They smile and they kiss. In the English language, there are many expressions using the word“mouth.”

For example, if you say bad things about a person, the person might protest(抗议)and say “Do not bad mouth me.” Sometimes, people say something to a friend or family member that they later regret because it hurts that person. Or they tell the person something they were not supposed to tell. The speaker might say: “I really put my foot in my mouth this time.”  If this should happen, the speaker might feel down in the mouth.  In other words, he might feel sad for saying the wrong thing.

Another situation is when someone falsely claims another person said something.  The other person might protest: “I did not say that.  Do not put words in my mouth.”

Some people have lots of money because they were born into a very rich family.  There is an expression for this, too. You might say such a person, “was born with a silver spoon in his mouth.” This rich person is the opposite of a person who lives from hand to mouth.  This person is very poor and only has enough money for the most important things in life, like food.

Parents might sometimes keep a child off sweet food as a form of punishment for saying bad things. For example, if a child says things she should not say to her parents, she might be described as a mouthy child. The parents might even tell the child to stop mouthing off..
