Along the river banks of the Amazon and the Orinoco there lives a bird that swims before it can fly, flies like a fat chicken, eats green leaves, has the stomach of a cow and has claws (爪) on its wings
when young. They build their homes about 4.6m above the river, an important feature (特征) for the safety of the young. It is called the hoatzin.
In appearance, the birds of both sexes look very much alike with brown on the back and cream and red on the underside. The head is small, with a large set of feathers on the top, bright red eyes, and blue skin. Its nearest relatives are the common birds, cuckoos. Its most striking feature, though, is only found in the young.
Baby hoatzins have a claw on the leading edge of each wing and another at the end of each wing tip. Using these four claws, together with the beak (喙), they can climb about in the bushes, looking very much like primitive birds must have done. When the young hoatzins have learned to fly, they lose their claws.
During the drier months between December and March hoatzins fly about the forest in groups of 20 to 30 birds, but in April, when the rainy season begins, they collect together in smaller living units of two to seven birds for producing purposes.

Cellphone feels like a part of your body? A global survey has found that most people can’t live without their mobiles, never leave home without them and, if given a choice, would rather lose their wallet.
Calling mobile phones the “remote control” for life, market research firm Synovate’s poll said cell phones are so ubiquitous that by last year more humans owned one than did not.
Three-quarters of the more than 8,000 respondents polled online in 11 countries said they take their phone with them everywhere, which Russians and Singaporeans the most attached.
More than a third also said they couldn’t live without their phone, topped by Taiwanese and again Singaporeans, while one in four would find it harder to replace the mobile than their purse.
Some two thirds of respondents go to bed with their phones nearby and can’t switch them off, even though they want to, because they’re afraid they’ll miss something.
Mobiles have changed the nature of relationships, with the survey finding a fifth of all respondents set up first dates via text and almost the same number use the same method to end a love affair.
Apart from the obvious calling and SMS-ing, the top three features people use regularly on their mobile phones globally are the alarm clock, the camera and the games.
As for email and Internet access, 17 percent of respondents said they checked their inboxes or surfed the Web on their phones, led by those in the United States and Britain.
One in 10 respondents log onto(注册) social networking websites such as Facebook and MySpace regularly via mobile, again led by Britain and the United States.
Not everyone is tech savvy(科技通), however,37 percent of respondents said they don’t know how to use all the functions on their phone.How many people of all respondents end a love affair via text?
| A．About 4,800. | B．About 3,600 | C．About 2,400. | D．About 1,600. |
According to the survey, like surfing the Internet with a cellphone most.
| A．Singaporeans | B．Russians | C．Americans | D．Chinese |
Which of the following functions of cellphones is the least used?
| A．Calling. | B．Playing games. | C．Taking photos. | D．Surfing the Internet. |
Which would be the best title of the passage?
| A．People can live better without the cellphone. | |
| B．People would rather lose their wallet than their cellphone. | |
| C．Different uses of the cellphone. | D．New functions of the cellphone. |
Are you a problem shopper? The answer is “Yes”, if you or someone else thinks that you sometimes get carried away with shopping. In other words, do you or does someone else think you are occupied in extreme shopping? If people have regrets later about their shopping, or have an “out-of-control” feeling about the quantities of what they buy or the amount of credit they use, they may be considered to be problem shoppers.
Extreme shopping can lead to a more serious problem — addictive shopping. Addictive shoppers feel driven by the desire to shop and spend money. They experience great tension which drives them to shop and spend money and they feel a “rush” during the time they are occupied with the shopping activity.
Extreme or addictive shopping may result from long-time unpleasant feelings, of which anxiety, pain and shame are common ones. When we feel bad inside, we often do something to make ourselves feel better. In this case, we often go shopping.
A few people shop to relieve their boredom or emptiness. For some people, the motivation is a desire for status, power, beauty or success. Some love to shop as it makes them feel valued in the eyes of the shop assistants. Others shop simply because it makes them forget, at least temporarily, tension, fear or unhappiness in their life.
Besides, shopping malls are designed to encourage continual shopping. For instance, there are some malls where you can’t see clocks displaying the time because they don’t want you to become too aware of the time you spend there. What’s more, food courts, coffee shops and restrooms are provided, so you don’t have to leave the mall because of your physical needs.
Therefore, once you become aware of how market forces work, you will certainly come to control your shopping behavior. For example, how much time you will spend and what areas you will visit can be decided before you enter the mall. Keep a written account of what items you will buy and how much money you will spend. Make a plan for what you are going to buy before you feel the urge to shop and then stick to it. That is vital for gaining self-control. Which of the following people may not be problem shoppers?
| A．Those who cannot control the amount of credit they use. |
| B．Those who just walk around the shopping malls. |
| C．Those who are occupied in too much shopping. |
| D．Those who feel sorry for their shopping. |
According to the passage, what may not result in addictive shopping?
| A．The awareness of how market forces work. | |
| B．The desire for status, power, beauty or success. | |
C．Boredom, emptiness, tension, fear or unhappiness in people’s life. |
D．Long-time bad feelings of anxiety, pain and shame. |
What does the author suggest to control our shopping behaviour?
| A．Never going to the shopping malls because there are many tricks. | |
| B．Applying for a credit card before we go shopping. | |
| C．Making the shopping time as short as possible. | D．Making a shopping list before we go shopping. |
The author writes this passage
to _______.
| A．inform the shopping malls how to attract more shoppers |
| B．provide solutions to the problem shopping |
| C．scold the problem shoppers |
| D．tell a shopping story |
With alarming regularity, we read about oil tankers having accidents near land and the terrible consequences of the oil spills(泄露) on people, nature, and the environment.
Millions of dollars have been used in developing special chemicals to help dismiss the spills and to clean up the animals, beaches, and land spoiled by the oil. Unfortunately, when many of these chemicals are used, more damage is caused to the environment, especially to lives in the sea.
Of all of today’s environmental disasters, an oil spill may actually be one of the least serious. Although oil is poisonous, it is a natural material. In the end, it breaks down naturally. There are, of course, long-term effects, but it is usually more serious in the short term.
Nature by itself works better than chemical materials, but when there is a spill we demand that governments act immediately with as much hi-tech knowledge as possible. In 1967 the tanker Torrey Canyon sank off the Scilly Isles near the coast of England and spilled 120,000 tones of oil into the ocean. If you go there today, you will find it hard to see any sign that it ever happened.
Governments seem to accept the risk of transporting millions of tons of oil by ship every day so that we can fill up our cars and drive around and cause even more environmental damage. Interestingly, the b
iggest companies in the world produce cars, and the next biggest supply the gasoline to make them run!
We should be thinking more about reducing our dependency on oil. Governments should be encouraging research into new technologies, such as cars run by solar power(太阳能), electricity, hydrogen, and so on. Much of this research has, in the past, been held back by the oil, gas, and coal.
If the world’s millions of cars were 10% more efficient(高效的) — and the industry could easily produce cars at least twice as efficient — we would need many fewer tankers crossing the oceans each year. If this happened, the risks of oil spills would be reduced, and the air we breathe would be cleaner and fresher, too.What is the passage mainly talking about?
| A．Oil spills pollution. | B．What oil pollution is. |
| C．Oil tanker accidents. | D．How to reduce oil pollution. |
How does the author support the idea that oil spills are not as serious as people believe?
| A．By giving a description. | B．By making an argument. |
C．By giving an example. |
D．By drawing a diagram. |
What does the underlined word “risk” in Paragraph 5 refer to?
| A．Transportation depending more on oil. | B．Poisonous oil breaking down naturally. |
| C．Millions of tons of oil spilling into the sea. | D．More environmental damage being caused. |
Which suggestion is made for reducing oil tank accidents according to the passage?
| A．We should build safer oil tankers in the near future. |
| B．We should develop new technologies to cut oil use. |
| C．Tankers should not be allowed to sail near the coastlines. |
| D．Countries should build more oil pipelines under the sea. |
The Pillow
At the age of sixteen, I joined a volunteer group with my dad. I went on my first volunteer project in West Virginia. On the night we arrived, we discovered that “our family” was living in a trailer (拖车) that was in poor condition. A crew had been working on it for two weeks, but every time they finished one problem, another surfaced.
We decided the only reasonable solution was to build a new house—something unusual but necessary under these circumstances. The family was overjoyed with their new house that was twenty by thirty feet with three bedrooms, a bath and a kitchen.
On Tuesday of that week,
while we ate lunch together, I asked the family’s three boys, Josh, Eric and Ryan, “What do you want for your new room?” Expecting toys and other gadgets that children usually ask for, we were astonished when Josh responded, “I just want a bed.”
The boys had never slept in a bed! They were accustomed to plastic mats. That night we had a meeting and decided that beds would be the perfect gift. On Thursday night, a few adults in our group drove to the nearest city and bought beds and new bedding.
When we saw the delivery truck coming, we told the family about the surprise. We could hardly contain ourselves. It was like watching excited children on Christmas morning.
That afternoon, as we fitted the frames of the beds together, Eric ran into the house to watch us. Too dirty to enter his room, he observed with wide-eyed enthusiasm from the doorway.
As my father slipped a pillowcase onto one of the pillows, Eric asked, “What is that?”
“A pillow,” he replied.
“What do you do with it?” Eric continued to ask.
“When you go to sleep, you put your head on it,” I answered softly. Tears came to my eyes as my father handed Eric the pillow.
“Oh…that’s soft,” he said, hugging it tightly.
Now, when my sister or I start to ask for something that seems urgent, my dad gently asks, “Do you have a pillow?”
We know exactly what he means. The writer’s first volunteer project was ______.
| A．working on a poor trailer | B．helping a poor family |
| C．donating beds and bedding | D．dealing with a housing problem |
On hearing Josh’s answer, the writer was shocked because ______.
| A．the family lived in a trailer | B．he expected to get some toys |
| C．he didn’t know what a bed was | D．the boys had no bed to sleep in |
From the passage, we can learn that Eric had never seen ______ before.
| A．a trailer | B．a truck | C．a pillow | D．a house |
By saying “Do you have a pillow?”, the writer’s father means that ______.
| A．what they want to get may be unnecessary |
| B．they should not waste money on small things |
| C．they should do more volunteer work for the poor |
D．what he w ill buy is not what they want but a pillow |
Microwaves may be great at warming up food, but what about warming people?
Using microwaves to directly heat owners of a room would save much of the energy wasted by heating walls and furn
iture. And despite popular ideas about microwaves, this technique would be safe, according to Charles R. Buffler of the Microwave Research Center in Marlborough, New Hampshire. Low-power microwaves only penetrate (贯穿) the skin (low-power microwave penetration in a ham is about 0.2 inches, for example) and with no negative effects.
To test this idea, Buffler subjected himself to microwaves in a special room using a standard 500-watt, 2459 MHz magnetron (磁控管). He found that a person will start to feel warmth at about 20 milliwatts per square centimeter (mw. /sq.cm.); a satisfactory feeling of warmth occurs between 35 and 50 mw./sq.cm. By comparison, a person standing in noonday summer sun feels the amount of 85 mw./sq.cm. And a frozen meat pie in your microwave oven receives about 1000 mw./sq. cm.
In houses of the future, each room could be provided with its own magnetron, says Buffler. When you stepped into the living room, for example, a motion detector would turn on the magnetron, filling the room with low-power microwaves. In the same way that a microwaves oven heats up a hamburger, but not the plate it’s on, you would feel warmth from the microwaves without changing the temperature of your coffee table. (You could, however, make your favorite easy chair even more comfortable by treating it with a radiation-absorbing chemical.)
While it might be some time before homeowners are comfortable enough with the idea to set up whole body microwave heaters in houses, Buffler says microwaves may attract livestock farmers. Lambs that are born outdoors in winter, for example, are frequently lost to cold. Microwaves could warm the lambs safely and quickly. Which of the following can tell the main idea of the passage?
| A．A new heating system. | B．A new microwave oven. |
| C．A popular technique. | D．The magnetron. |
The test conducted by Buffler shows that when a person feels comfortable warmth, he receives about ____.
| A．20 mw. / sq. cm. | B．40 mw. / sq. cm. |
| C．60 mw. / sq. cm. | D．85 mw. / sq. cm. |
According to paragraph 4, which of the following fills the room with low-power microwaves?
| A．The magnetron. | B．The motion detector. |
| C．The microwave oven. | D．The radiation-absorbing chemical. |
Which of the following statements about microwave heaters would Buffler most probably agree with?
| A．Microwave heaters will soon be widely used by homeowners. |
| B．Microwave heaters sometimes make people feel uncomfortable. |
C．Microwave heaters will be probably first used by livestock farmers to prot ect their lambs in winter. |
| D．Microwave heaters cannot be accepted by the public because they are somewhat unsafe. |
