According to the American Automobile Association , since 1964 all cars sold in the United States have been equipped with seat belts (These are also called safety belts.) . Many studies of automobile accidents have shown that safety belts can save lives. One study showed that forty percent of those killed in auto accidents could have been saved if they had been wearing seat belts.
Unfortunately, belts are worn only by a small percentage of drivers and passengers — about fifteen percent in cities, and only nine percent in small towns. And safety belts cannot protect people who do not wear them.
In order to find out what kinds of people do wear seat belts, a study was made in several cities of the United States. The following facts were about those who use their safety belts:
1. They do not smoke while driving.
2. They have had more education than non-users.
3. They know someone who was injured (but not killed) in an automobile accident.
Advertisements based on these facts have been printed in newspapers and magazines in order to teach people the importance of using seat belts. But these advertisements have not helped much. Some people believe there should be a law requiring drivers and passengers to use safety belts. In Australia, where there is such a law, deaths in auto accidents have decreased twenty-four percent.The passage is mainly about ______.
| A．automobiles in the United States | B．accidents involving cars |
| C．safety belts for drivers and passengers | D．traffic jams |
The passage tells us that in Australia ______.
| A．a law requires drivers and passengers to use seat belts |
| B．about 50% of the drivers wear seat belts |
| C．the importance of seat belts is advertised in newspapers and magazines |
| D．the auto accidents have kept the same percent as in the US |
People who live in small towns _____.
| A．have fewer accidents than those who live in cities |
| B．are less likely to use seat belts than those who live in cities |
| C．welcome the passing of a law to require the use of seat belts |
| D．are against the law that requires people to use seat belts |
Many studies have shown that seat belts can save lives of those who ______.
| A．never wear seat belts |
| B．seldom wear seat belts |
| C．are wearing seat belts when the accidents happen |
| D．sit at the back of the cars |

The Couch Surfing network is an online community stretching across the globe with over one and a half million members．The basic concept is to provide a platform for travelers to contact people who are willing to put them up free of charge．Travelers connect with potential hosts online and, if they like each other, exchange details to make further arrangements．
Basil is one traveler from Switzerland who is currently couch surfing with a Chinese host in Beijmg．"I thought staying in hostel is nice but you mostly meet foreigners and speak English．If you use Couch Surfing you have chance to meet people living here and really get a chance to know the life of the place you visit．" Basil was speaking during a regular meeting of the Beijing network of Couch Surfing with a membership of almost 2,000．
Although some people may have concerns about meeting complete strangers and giving them full access to your house, Beijing group member Fred Sharp from California says that the Couch Surfing community is one that generally attracts trustworthy people．
"I have never had a problem with guests。I'd say that this Couch Surfing community worldwide is a fairly trustworthy community Like I say, always be cautious, make sure that you read everyone's profile that you're considering hosting, and if it doesn't feel right just say 'no', it's ok．"
Originally launched in the US as a non-profit organization in 2004, Couch Surfing is growing fast across the world．China is no exception with around 30,000 members and hundreds more signing up each week．One of them is Beijing resident Hai Yan who joined in November 2009．She says the first time she hosted a guest was a very positive experience．"My first guest was from Italy He was very kind and helpful．He bought me a present from Italy, a handbag．It's a famous brand!"
As the organization grows from strength to strength, hotel owners across the world will be watching very closely and possibly thinking twice about raising their prices too high．

A
The old man walked slowly into the restaurant. With head tilted, and shoulders bent forward he leaned on his trusty stick with each unhurried step. His torn cloth jacket, patched trousers, worn out shoes, and warm personality made him stand out from the usual Saturday morning breakfast crowd. He stopped, turned with his whole body, and winked at a little girl seated by the door. She flashed a big smile right back at him.
A young waitress named Mary watched him walk toward a table by the window. She ran over to him, and said, "Here, Sir. Let me give you a hand with that chair." She pulled the chair away from the table. Steadying him with one arm, she helped him move in front of the chair, and get comfortably seated. Then she moved the table up close to him, and leaned his stick against the table where he could reach it.
In a soft, clear voice he said, "Thank you, Miss. And bless you for your kind gestures."
"You're welcome, Sir." She replied. "And my name is Mary. I'll be back in a moment, and if you need anything at all in the mean time, just wave at me!"
After he had finished a hearty meal, Mary brought him the change from his ticket. He left it on the table. She helped him and walked with him to the front door. Holding the door open for him, she said, "Come back and see us, Sir!" He turned and nodded a thank-you. "You are very kind." he said softly, smiling.
When Mary went to clean his table, she almost fainted. Under his plate she found a business card, and a note scribbled on a napkin. Under the napkin was a one-hundred-dollar bill.
The note on the napkin read, "Dear Mary, I respect you very much, and you respect yourself too. It shows by the way you treat others. You have found the secret of happiness. Your kind gestures will shine through those who meet you."
The man she had waited on was the owner of the restaurant where she worked. This was the first time that she, or any of his employees had ever seen him in person.

Could we "terraform" Mars —that is, change its frozen, thin-aired surface into something more friendly and Earthlike? Should we? The first question has a clear answer: Yes, we probably could．Spacecraft, including the ones now exploring Mars, have found evidence that it was warm in its youth, with rivers flowing into vast seas．And right here on Earth, we've learned how to warm a planet: just add greenhouse gases to its atmosphere．Much of the CO2 that once warmed Mars is probably still there, in frozen dirt and polar ice caps, and so is the water．
Most of the work in terraforming, says NASA scientist Chris Mackay, would be done by life itself． "You don't build Mars," Mackay says．"You just warm it up and throw some seeds．" Powerful greenhouse gases could be produced from elements in dirt and air on Mars and blown into the atmosphere; by warming the planet, they would release the frozen CO2, which would quicken the warming and increase atmospheric pressure to the point where liquid water could flow．Meanwhile, says botanist James Graham of the University of Wisconsin, human settlers could seed the red rock with a succession （系列） of ecosystems ?first bacteria and lichens （地衣）, which survive in Antarctica, later mosses （苔藓）, and after one thousand years or so, redwoods．Getting breathable oxygen levels out of those forests, though, could take thousands of years．
However, Mars is in no immediate danger．Some space scientists recently recommended going to the moon or an asteroid （小行星） first, and pointed out the space agency lacks the funds to go anywhere．It didn't estimate the cost of gardening a dead planet．
72．What is the most essential to make Mars fit for living?
A．Turn ice into flowing water． B．Clean the dirty atmosphere．
C．Make the atmosphere more suitable． D．Go to the moon or an asteroid first．
73．What does the author think of the idea ofterraforming Mars?
A．We could do it． B．We couldn't do it．
C．We should do it． D．We shouldn't do it．
74．In the botanist's opinion, man needs to __________.
A．enable Mars to clean its atmosphere
B．build a greenhouse on Mars
C．send some people to settle on Mars
D．cultivate ecosystems from lower to higher life form
75．What is the best title for the passage?
A．Making Mars the New Earth． B．A Good Way to Change the Universe
C．Humans' Great Power． D．Terrible Science and Technology．
D
If you want to live longer and lower the risk of heart disease, a move to the mountains may help． Research by scientists in Greece shows that living in the mountains is good for the heart and longevity． People living at higher altitude have lower possibility of dying from heart disease than those closer to sea level, even if they have factors that could increase their risk．"Residence in mountainous areas seems to have a 'protective effect' from heart disease," said Dr Nikos Baibas of the University of Athens．He and his colleagues suspect that the increased exercise from walking up mountainous area gives the heart a good workout and enables it to cope with lower levels of oxygen．
Researchers studied the health records and death rates of 1,150 Greeks who lived in three villages near Athens over 15 years．One village was 1,000 metres above sea level and the other two were in low-lying areas．Although men and women living in the mountainous village had higher blood pressure rates and other risk factors than people in the other villages, they had a lower rate of death from heart disease and other causes after a fifteen year follow-up．"The contrast was more evident among men than among women," Baibas added in a report in the Journal of Epidemiology and Community Health．Heart disease is one of the world's top killers．Smoking, high blood pressure, raised cholesterol levels, being overweight or obese and a family history of the illness increase the odds of developing the disease．
68．The first sentence in the passage is used to __________．
A．tell readers what the passage focuses on
B．give a very good guessing
C．warn people of the risk of heart disease
D．name a new unknown illness

A．with more money B．with a better living habit
C．from higher altitude D．in a happier mood
70．How long does the research of the Greeks last?
A．At most 10 years． B．About 15 years．
C．More than 20 years． D．Not mentioned．
71．Apart from altitude, how many factors raise the chance of developing heart disease?

I'm really nervous opening Chatroulette （a website）．I don't know if I'm more scared of the possibility of coming face-to-face with a naked （裸体的） guy doing improper things, or the possibility of having to speak to someone normal．But it's that uncertainty that's caused the "game" to explode into an Internet phenomenon．
So, I hesitantly click "play"．My face appears in a small box to the left of the screen．I'm a 22-year-old guy, wearing jeans and a T-shirt, and sitting in my warmly lit bedroom —not too threatening, I think．Believing I look welcoming and friendly, I open all features: visual, audio and text．The user can disable these at any time if they feel uncomfortable．
Quickly I find myself face-to-face with my first "partner"．A guy with glasses is staring back at me．He looks like he spends too much time in front of the computer．"Hey", I say, "how are you going?" "Good," says the guy．Sensing that he was not going to be very talkative, I hit the "next" button．
Just like that, I'm thrown across the world into someone else's bedroom．This time it looks like a middle-aged woman．I must have hit gold because 85 percent of Chatroulette users are male, according to the Wall Street Journal．She's wearing sunglasses and smiles back．Before I can even say a word, she "nexts" me．"WHAT?!"
Then, I fly through the Internet and arrive at my next partner．My nightmare, a man is sitting in his computer chair half-naked taking off his pants．Argghh! "Next, next, next!" For the next 30 minutes I keep my cursor （光标） over the "next" button．My experiences continue to be short, shocking, and largely uninteresting．I discouragingly hit "next" after seeing another naked man, and decide to end my session and close the window．This wasn't "the new social media experience" I was hoping for．Maybe it was just a little bit too random （随机的）．
64．It is the author's __________ that leads him into Chatroulette．
A．curiosity B．unwillingness C．enthusiasm D．ignorance
65．The underlined word "disable" in Paragraph 2 means __________．
A．store B．close C．misuse D．copy
66．Among all the partners, __________ seemed to be the least interested in talking with the author.
A．the guy with glasses B．the middle-aged woman
C．the man in his computer chair D．the last man mentioned
67．What is the author's attitude toward Charoulette?
