题目内容

More than 700 business leaders, government officials and investors gathered in Mountain View, California in December,2012 to attend the Social Innovation（创新）Summit．It is an invitation-only conference aimed at finding new ways to deal with old problems．

Traffic jam is a problem that Bruggemann hopes to solve．“Traffic is really bad in most countries and we thought there must be some way of doing something about it．”Last week, his team, winning the prize for its“nunav”traffic management system, received a Microsoft Imagine Cup Grant of ＄100，000．“Everyone that′s using our system sends his present position as well as the destination to our servers every 30 seconds．And with that information our central system can reroute（调整路线）all of the cars in a way that everyone gets his individual best possible route．”

Bruggemann says early research with the system has been promising．“We found out that it could be possible to save up to 20 percent of the fuel consumption．Even more interesting, it can save up to 50 percent of the time you spend in traffic so you could get to your destination twice as fast．”

Team Cypher256 from Uganda also was invited to the Social Innovation Summit．They developed a device（仪器），called WinSenga, aimed at improving health care for pregnant women in Africa．It measures the early baby′s heart sounds to help test the heart rate, age and position of the baby in the mother．The device is similar in operation to an ultrasound（超声波）test, but is far less costly and very practical in Africa．

This is the third year for the Social Innovation Summit．The event is held twice a year, once in New York and once in California．The first one in 2012 was held in May． The United Nations′Office for Partnerships helped to organize the event．

61．In what way is the“nunav”system special？

A．It can decide destination for users．

B．It sends back information every 30 minutes．

C．Users can earn much money by the system．

D．Users can find the best possible route by the system．

62．The“nunav”system has the following advantages EXCEPT___________．

A．reducing the fuel consumption B．reaching the destination quickly

C．saving the time in the trip D．improving driving skills

63．The device WinSenga is intended to___________．

A．improve the health care for pregnant women

B．promote the heart rate of pregnant women

A．The“nunav”system is popular in Africa．

B．Common people in Africa can afford to use WinSenga．

C．The United Nations offered financial help to the“nunav”system．

D．The Social Innovation Summit has been held three times so far．

65．What′s the purpose of the text？

It was a dark and cold night. The car driver didn’t have even one passenger all day. When he went by the railway station, he saw a young man coming out with two bags in his hands. So he quickly opened the door of the car and asked, “Where do you want to go, sir?”

“To the Star Hotel,” the young man answered. When the car driver heard that, he didn’t feel happy. The young man would give him only three dollars because the hotel was not far from the railway station. But suddenly, he had an idea. He took the passenger through many streets of the big city.

After a long time, the car finally arrived at the hotel. “You should pay me fifteen dollars,” the car driver said to the young man. “What! Fifteen dollars? Do you think I’m a fool? Only last week I took a car from the railway station to this same hotel and I only gave the driver thirteen dollars. I know how much I have to pay for the trip.

Paloalto, California— “Turning off the television may help prevent children from getting fatter—even if they do not change their diet,” US researchers said last week.

A study of 192 third and fourth graders, generally aged eight and nine found that children who cut the number of hours spent watching television increased nearly two pounds (0.91kg) less over a one-year period than those who did not change their television diet.

“The findings are important because they show that weight loss can only be the result of a reduction in television viewing and not any other activity,” said Thomas Robinson, a pediatrician (儿科专家) at Stanford University. “American children spend an average of more than four hours per day watching television and videos or playing video games. And rates of childhood being very fat have doubled over the past 20 years,” Robinsin said.

In the study presented this week to the Pediatric Academic Societies annual meeting in San Francisco, the researchers persuaded about 100 of the students to reduce their television viewing by one-quarter to one-third. Children watching fewer hours of television showed a much smaller increase in waist (腰) size and had less body fat than other students who continued their normal television viewing, even though neither group ate a special diet nor took part in any extra exercise.

“One explanation for the weight loss could be the children unstuck to the television may simply have been moving around more and burning off calories,” Robinson said. “Another reason might be eating fewer meals in front of the television. Some studies have suggested that eating in front of the TV encourages people to eat more,” Robinson said.

The report tells us that children will get fatter if they ________.

A. eat in front of the TV B. change their diet

C. do special exercises D. spend much time watching TV

According to the report, the time American children usually spend on watching TV and videos or playing video games ________.

A. one hour B. two hours C. three hours D. four hours

Watching TV will increase kid’s weight because ________.

Andy Tomas is proof of the typical case that life-changing disaster awaits the drunken driver.

“A lot of teachers say, ‘Don’t drink,’ but I’m not going to say that, because I know that students are going to do it,” Andy says. “I just say, ‘Don’t get in a car.’”

As an 18-year-old, he could be a classmate or a friend, and that familiarity adds to the power of his words. He has spoken to more than 2500 high school students so far, and he has noticed their unusual silence.

One year ago, Andy, having been with friends drinking, lost control of his car and was thrown into trees 20 feet away. He was found covered in blood, with many bones broken. He was diagnosed with a severe brain injury and remained in an unconscious state and on life support for nearly three weeks. His skull was opened to reduce pressure on his brain.

At Children’s Specialized Hospital in New Brunswick, Doctor Erin Leahy initially found Andy unable to move the right side of his body. But by the end of his six-week stay, he was able to walk out of the building. Leahy called that an inspiration and a surprise.

Yet Andy’s recovery is incomplete. Brain and muscular therapy(治疗) has helped him regain movement in his right arm, but he still struggles with right hand.

In the process of recovery, Andy has thought deeply about what happened and why, and decided to share his story. Encouraged by his doctor, he began to attending meetings, delivering speeches.

He said he was nervous at first, but has grown used to the spotlight. “I feel like I know how to talk to people.” He said. And his recovery and visible injury help him draw serious attention from students.

Drunk driving, he tells students, is like playing gambles. “You might do it a bunch of times, but something is going to happen.”

Now his days are all about the therapy, work and going to the gym. Mentally, he says, “ I’m a lot happier in my life.”

What’s the main purpose of the author?

A. Warn students about the danger of drinking.

B. Tell readers the danger of driving a car.

C. Advise people not to drive a car after drinking.

D. Show readers Andy’s amazing recovery experience.

Why does the author say Andy’s story is powerful as an 18-year-old boy?

A. Because his family supported him and cared for him carefully.

B. Because he is just like one of our classmates or friends.

C. Because doctors and family never gave him up.[

D. Because his classmates and friends are familiar with him.

What does the underlined sentence mean?

A. Drunk driving will be fined a lot of money eventually.

B. Drunk driving will eventually have a serious accident.

C. Drunk driving is as adventurous and thrilled as gamble.

D. Drunk driving is banned even if you are an experienced driver.

What happened to Andy after the accident?

A. He made a full recovery and returned to his normal life.

B. He recovered quite well at an unbelievable speed.

C. He became more experienced and eager for more adventures.

D. He shared his stories with others to warn them not to try drunk driving.

　For more than twenty years scientists have been searching for signs of life on other planets. Most of these searches have been done over the radio. The hope is that someone in outer space may be trying to get in touch with us. Scientists also have sent radio and television messages on spaceships traveling through space, on the chance that someone may be receptive to such messages.

　　Scientists are using powerful radio telescopes to listen to signals from about 1, 000 stars, all within 100 light years of earth. In addition, they will scan（扫视）the entire sky to “listen” for radio messages from more distant stars. Using a computer, they will be able to monitor more than eight channels at one time. Scientists are looking for any signal they stands out from the background noise.

　　Of the 200 billion stars in the Milky Way galaxy（银河星系）, scientists find that five percent are like our sun. Perhaps half of them have a planet like earth. Such a planet would be a reasonable distance from the star for temperatures to be right for the evolution（进化）of life. Based on the inhabitable（that can be lived in）planets in our galaxy, most scientists agree that chances are likely that one or more of these planets support some life.

　　However, many scientists wonder whether intelligent（有智力的）life exists on other planets. Some believe that twenty years of searching without any intelligible messages shows that no one is out there. They say that the evolution of intelligence comparable to ours is unlikely.

　　Other scientists believe that our search hasn’t been long enough to rule out the possibility that intelligent life exists in our galaxy. Although our sun family is only about five billion years old, our galaxy is about 20 billion years old. In that time, some scientists think it is likely that civilization（文明）much more advanced than ours have developed. Perhaps these civilizations send us no signals; perhaps we have not recognized the signals they have sent us. If we hope to find intelligent life, these scientists believe that we have to keep looking.

According to the passage, how many planets in our galaxy might be inhabitable?

　　A. 5 billion．　　　　　　　　　　 B. 10 billion.

　　C. 15 billion.　　　　　　　　　　　D. 200 billion

The first paragraph in this passage is mainly about ________ .

　　A. how scientists are looking for signs of life on other planets

　　B. why scientists are looking for signs of life on other planets

　　C. where scientists are looking for signs of life on other planets

　　D. when scientists are looking for signs of life on other planets

The underlined word “monitor” in the passage means“ ________ ”.

　　A. find　　　　　　　　　　　　　B. follow

　　C. check　　　　　　　　　　　　 D. form

Which of these statements is true based on the information in the passage?

　　A. The earth is one of the oldest planets in our galaxy.

　　B. Most scientists believe that there is intelligent life on other planets.

　　C. Scientists are trying different ways to find signs of life on other planets.

D. Scientists don’t believe that there might be life on other planets.
