Driving while talking on a hand-held mobile phone has long been considered a danger. But even drivers who use hands free devices are a nuisance – because they are slowing everyone else down, according to a study.
David Strayer, a psychology professor in Utah University’s traffic lab, conducted a study involving 36 university students driving on motorways. Each used a hands free phone for half the trip but not for the other half. The students were told to obey posted speed limits and use turn signals but the rest of the driving decisions were up to them . What Strayer found is that when the drivers were distracted（使分心）by a phone conversation , they made fewer lane（車道） changes, drove slower and took longer to get where they were going. Fellow researcher Professor Peter Martin, who teaches civil and environmental engineering at Utat University, said,“Ordinarily a slower driver should be safer ， but that’s not the case when people are talking on a cell phone.”
In general , drivers who used mobile phones while driving took three percent longer to drive along the same high-density route than drivers who didn’t. When stuck behind a dawdling(磨蹭的) driver , it took them between 25 and 50 seconds longer to switch to an open lane to overtake. Those delays can add up when you consider studies that suggest as many as 10 percent of US drivers are using a cell phone at any one time. And delays in traffic streams of very small amounts can grow into massively when drivers are crossing a  highway.” Our next step is to use computer models to determine just how much those delays are costing drivers in time and in extra fuel costs,” Martrin said.
63. What does the underlined word in the first paragraph mean?
A. A person who is a volunteer.         B. A person who breaks the traffic law
C. A person who is annoyed by others.   D. A person who causes trouble
64. Which of the following is TRUE , according to Martin?
A. The more slowly a person drove, the safer he was.
B. Measures should be taken to stop using mobile phones.
C. Drivers using hand-held phones had less effect on traffic than those using hands free phones
D. Driving while using mobile phones could cost drivers time and money.
65. The passage is mainly about      .
A. traffic conditions in rush hours 
B. the use of mobile phones in the USA
C. using hands free devices behind the wheel
D. a comparison between hand-held phones and hands free ones

         According to the report by Baekeland and Hartmann, two American authoritative psychotogical research centres, the "short sleepers" had been more or less average in their sleep needs until the men were in their teens．But at about age 15 or so, the men voluntarily began cutting down their nightly sleep time because of pressures from school, work and other activities. These men tended to view their nightly periods of unconsciousness as bothersome interruptions, in their daily routines.
In general, these "short sleeps" appeared ambitious, active, energetic, cheerful,, conformist （循規(guī)蹈矩的） in their opinions, and very sure about their career choices．They often held several jobs at once, or workers full - or part - time while going to school．And many of them had a strong urge to appear "normal" or "acceptable" to their friends and associates．When asked to recall their dreams, the "short sleepers" did poorly．More than this, they seemed to prefer not remembering．In similar fashion, their usual way of dealing with psychological problems was to deny that the problem existed, and then to keep busy m the hope that the trouble would go away．The sleep patterns of the “short sleepers" were similar to, but less extreme than, sleep patterns shown by many mental patients categorized as manic （瘋?cè)耍?
The "long sleepers" were quite different indeed．Baekeland and Hartmann report that these young men had been lengthy sleeps since childhood．They seemed to enjoy their sleep, protected it, and were quite concerned when they were occasionally deprived （剝奪） of their desired 9 hours of nightly bed rest．They tended to recall their dreams much better than the "short sleepers．" did．Many of the "long sleepers" were shy, anxious, introverted （內(nèi)向）, inhibited （壓抑） , passive, mildly depressed, and unsure of themselves （particularly in social situations）．Several openly states that sleep was an escape from their daily problems．
50．According to the text, which is probably the writer' s real attitude towards these two living habits ____．
A．both of them are healthy habits  
B．not both of them are unhealthy habits
C．either of them is not unhealthy habits
D．neither of them is healthy habits
51．When sometimes they cannot enjoy adequate sleep, the long sleepers might ____．
A．feel extremely depressed         B．become energetic
C．a(chǎn)ppeared disturbed          D．feel disappointed
52．The writer implies （暗示） that short sleepers _____ in the text．

When you look at a map of the Caribbean, you will see a bunch of little islands surrounded by. Blue waters, which include places that aren't always household names like Montserrat and Anguilla.
While some of the names may not be familiar, the fact is that the Caribbean is a popular vacation region. Those little clots on the map often turn out to be island paradises. There are more than 7,000 islands, islets, and reefs in the area, many of which are lightly populated and stunningly beautiful.

You can enjoy the waters in most of the Caribbean nations and as is often the case with island nations, you will be welcomed warmly by the locals. Here are some resources to help you.
Unless you can walk on water or you cruise the Caribbean, the best way to visit is to fly. Some destinations have more frequent and cheaper flights than others. You should do some comparison shopping on flights to the Caribbean. And if you are planning on flying there during the Christmas holiday weeks it's important to book as early as possible because prices will just keep going up as they get closer.
The Caribbean offers a wide variety of accommodation options. Check out the Caribbean hotels that are available to get a better idea of the various options. If you are on a tight budget then, the Caribbean could be challenging, as there are only a few cheap hotels and hostels that might help you save some money.

We need to make better use of our resources. In developing countries we have more than enough, if we are less wasteful in our ways. Fortunately, we can improve. The challenge lies not so much with ‘technical fixes’ but with our approach to our world around us. In the recent past we were in a “Wild West” economy, supposing that there would always be enough resources. Now we know there are no new Earth to explore and exploit; one image to illustrate this is to think of Earth as a spaceship, where most materials have to be recycled. For us, “moving on” will be a case of leaving behind the throwaway society and advancing to a conserver society.
To qualify as citizens of a conserver society, we must change traditional attitudes and thinking. We need to recognize that there is not very often such a thing as “waste”, rather, there are materials which sometimes end up in the wrong place. The change has already begun. The European steel industry reuses scrap（廢棄的）metal, resulting in an energy saving of up to 50% . Recycling a glass container saves only 18%; but, in parts of the United States, a citizen buying a bottle of soda or beer now pays a deposit against return of the empty bottle.
If all drink containers in the USA were to be reused, the annual saving would be 0.5 million tons glass, plus about 50 million barrels of oil used in production processes. In Japan, OPEC promoted an increase in recycling of raw materials from 16% to 48% in just five years. In Norway, the price of a new car includes a disposal cost element of about 100 dollars, redeemable（可換成現(xiàn)款的）when the junked car is turned in at an approved receiving center.
Major new businesses are trying to exploit waste chemicals and oil. The Chinese claim to reuse 2.5 million tons of scrap iron and at least one million tons of waste paper each year. In the main, the conserver society depends on the commitment of individuals. But they can be encouraged by government incentive(鼓勵(lì)) and punishment, which should apply at least as strongly to industry and other commercial interests.
73  Which of the following best expresses the meaning of “a conserver society” in the second paragraph?
A. A wasteful society.
B. A society which thinks of  ways of recycling waste materials.
C. A society which keeps everything.
D. A society which saves electricity.
74  In the last paragraph, the author suggests governments _______.
A. depends on individuals to find ways of conserving energy.
B. find ways of encouraging those industries and individuals who conserve energy and of punishing those who don’t.
C. depend on companies to find ways of saving energy and rewarding workers
D. help establish businesses that will exploit waste materials
75  In this passage the author _______.
A. explains that meaning of the “Wild West” economy
B. tells us what recycled materials are.
C. teaches us how to recycle materials.
D. recommend a change in our use of resources strongly

Millions of young people are writing blogs. Millions of others are reading them. The word "blog" is a short way of saying Web log.
Many popular Web sites now offer free, easy ways to create personal Web pages and fill them with writings and pictures. Web sites called "Facebook" and "MySpace" are some of the most popular blog sites for young people. Many young adults use their blogs to write about daily activities and events in their lives. They also provide a place for people to write their ideas and opinions and how they think of others’ ideas.
Blogs offer young people a place to show their writings and feelings. They can also be helpful to connect young people with others. But blogs can become dangerous when they are read on the Internet by millions of people all over the world.
Recent studies show that young people often provide their names, age and where they live on the Internet. That may not be safe for them. This personal information puts them at risk of being searched out by dangerous people who want to hurt them. Many students do not know about privacy and are surprised to learn that adults can read their personal daily records easily. Students can also get into trouble when they put information about others on their blogs. 
As a result, many schools have banned the use of blogging web sites on school computers. Many schools have also begun teaching parents about the web sites. Parents should know what their children are doing online and should read their blogs to make sure they are not giving out private information. One way to keep away from these problems is to use programs so that blogs can be read by "friends only." people can read the website only if they know a secret word chosen by the blogger.

A
Why You Should Celebrate Your Mistakes
When you make a mistake, big or small, cherish (珍視) it like it’s the most precious thing in the world. Because in some ways, it is.
Most of us feel bad when we make mistakes, beat ourselves up about it, feel like failures, get mad at ourselves.
And that’s only natural: most of us have been taught from a young age that mistakes are bad, that we should try to avoid mistakes. We’ve been scolded when we make mistakes—at home, school and work. Maybe not always, but probably enough times to make feeling bad about mistakes an unconscious reaction.
Yet without mistakes, we could not learn or grow. If you think about it that way, mistakes should be cherished and celebrated for being one of the most amazing things in the world: they make learning possible; they make growth and improvement possible.
By trial and error—trying things, making mistakes, and learning from those mistakes—we have figured out how to make electric light, to paint the ceiling of the Sistine Chapel, to fly.
Mistakes make walking possible for the smallest toddler, make speech possible, make works of genius possible.
Think about how we learn: we don’t just consume information about something and instantly know it or know how to do it. You don’t just read about painting, or writing, or computer programming, or baking, or playing the piano, and know how to do them right away. Instead, you get information about something, from reading or from another person or from observing usually … then you construct a model in your mind … then you test it out by trying it in the real world … then you make mistakes … then you revise the model based on the results of your real-world experimentation … and repeat, making mistakes, learning from those mistakes, until you’ve pretty much learned how to do something. That’s how we learn as babies and toddlers, and how we learn as adults. Mistakes are how we learn to do something new—because if you succeed at something, it’s probably something you already knew how to do. You haven’t really grown much from that success—at most it’s the last step on your journey, not the whole journey. Most of the journey was made up of mistakes, if it’s a good journey.
So if you value learning, if you value growing and improving, then you should value mistakes. They are amazing things that make a world of brilliance possible.
56. Why do most of us feel bad about making mistakes?
A. Because mistakes make us suffer a lot.
B. Because it’s a natural part in our life.
C. Because we’ve been taught so from a young age.
D. Because mistakes have ruined many people’s careers.
57. According to the passage, what is the right attitude to mistakes?
A. We should try to avoid making mistakes.
B. We should owe great inventions mainly to mistakes.
C. We should treat mistakes as good chances to learn.
D. We should make feeling bad about mistakes an unconscious reaction.
58. The underlined word “toddler” in Paragraph Six probably means _______.
A. a small child learning to walk             B. a kindergarten child learning to draw
C. a primary pupil learning to read                     D. a school teenager learning to write
59. We can learn from the passage that _______.
A. most of us can really grow from success
B. growing and improving are based on mistakes
C. mistakes are the most precious things in the world 
D. we read about something and know how to do it right away

People like to look in the mirror often when they have a young and beautiful face. However, when one grows old, nobody wants to see their wrinkled old face in the mirror any more. So, many old people seldom look at their faces in the mirror. This is completely wrong.
According to Wu Zhenyun, a professor from the Psychological Research Institute under the Chinese Academy of Sciences, a person’s willingness to look in the mirror can reflect his or her mentality. When people don’t care too much about their age, they will try to carry themselves with ease and natural poise (姿態(tài)). They don’t mind looking in the mirror to see their own faces. Some people even love to look in the mirror from time to time to see whether they keep a good appearance. In this way, mirror becomes their best friend that help them to look confident.
On the other hand, some people are afraid of being old. They don’t want to see the wrinkles on their face and their hair turning grey. So they don’t want to look in the mirror. This actually reflects a negative attitude they hold towards life. In the long term, they might suffer from psychological pressure or some sort of depression, which is actually not a wise act.
“ Everyone can make themselves look charming at every age stage. If one is confident, one will always look beautiful, it shows that they accept themselves.” professor Wu said.
Mirror cannot only give confidence to one. By looking in the mirror, one can even find the traces of some diseases from one’s own face.
67.Why does the mirror become the best friend for some people?
A. Because it brings much confidence to them.
B. Because it makes them more beautiful.
C. Because it tells whether they are clean or not.
D. Because it helps them find their own faults.
68.The fact that some people are afraid of looking in the mirror reflects that______.
A. they suffer from metal disease  B. they treat life in a negative way      
C. they are too ugly              D. they can’t bear the pressure of being old
69. The text tells us that______.
A. if you are willing to look in the mirror you are getting old
B. everyone can become attractive at any age
C. confidence can make a person look beautiful
D. old people will accept the reality when they are old
70. The writer wrote this passage to______.
A. advise people to look in the mirror constantly
B. reflect different attitude towards looking into a mirror

What’s that smell? Do you hear that noise? Taste this! Look at me! Feel this, isn’t it soft? When you hear, or even use these phrases, you probably don’t stop to think about why we use them. Well, it’s because of our senses. Without us even knowing, our sense organs (nose, eyes, ears, tongue, and skin) are taking in information and sending it to the brain for processing. If we didn’t have them, we would not be able to smell, see, hear, taste, or touch anything!
Senses are the physical means by which all living things see, hear, smell, taste, and touch. Each sense collects information about the world and detects changes within the body. Both people and animals get all of their knowledge from their senses, and that is why senses are so important.
All senses depend on the working nerve system. Our sense organs start to work when something stimulates（刺激） special nerve cells, called receptors, in a sense organ. Once stimulated, the receptors send nerve impulses along sensory nerves to the brain. Your brain then tells you what to do. For example, your sound receptors are often attacked by billions of sound waves. When these signals reach the part of the brain called the cerebral cortex（大腦皮層）, we become conscious of the sounds.
Our group really learned a lot about the senses while creating this website. We hope that you are able to get just as much out of it. Please feel free to comment about anything on the site by e-mailing us. Also, don’t forget to sign the guest book! Thanks for visiting our site. Come back soon!

Plants are very important living things. Life could not go on if there were no plants. This is because plants can make food from air,water and sunlight. Animals and man cannot make food from air,water and sunlight. Animals get their food by eating plants and other animals.Therefore animals and man need plants in order to live.This is why we find that there are so many plants around us.
If you look carefully at the plants around you,you will find that there are two kinds of plants:flowering plants and non-flowering plants.
Flowering plants can make seeds（種子）. The seeds are protected by the fruits. Some fruits have one seed, some have two, three or four, and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit. Most non-flowering plants do not grow from seeds. They grow from spores（胚芽）. Spores are very small. Some spores are so small and light that they can float in the air. We may say that spores are quite the same as seeds. When these spores are all on wet and shady places, they usually grow into new plants.
72. The main idea of the first paragraph is that ______.
A. plants are important for life             B. plants cannot grow without air
C. there are many plants in the world      D. we can not live without water
73. Plants can make food from______.
A. flower, water and air                                        B. water, sunlight and air
