　　　Most city parks are places where you can escape from big, ugly structures of metal and stone. The Manhattan High Line is different. Raised 25 feet above the ground, this massive metal structure once supported a rail line. The line opened in 1934 to bring trains directly into factories and warehouses. It was hardly used after the 1960s, and much of it was torn down. However, one section remained in an area of Manhattan called Chelsea. Chelsea was becoming more and more valuable as restaurants, art galleries and apartments were built, but the ugly railway structure remained as a dead weight. Everyone knew that at some time, it would have to be removed. 

　　　    But the High Line was not destroyed. In fact, now the old rail line serves as one of the most peaceful places in the city. It holds an elevated park, with beautiful gardens, a sidewalk and great views of the city. The idea to change the rail line into a park came from Joshua David and Robert Hammond. In 1999, they attended a community meeting to decide the fate(命运) of the High Line. David and Hammond were the only people at the meeting interested in saving the structure for its historical significance. Later on, when they asked railway officials to take them up to look at the High Line, they saw a mile and a half of wild flowers growing in the middle of the city, and they realized that the High Line had potential to become a park. There was growing interest in improving urban centers, and so the project quickly won support and funds for construction were easily obtained. 

　　　  The first section of the High Line opened in 2009 and immediately became popular with tourists and locals alike. Each part of the park has a different atmosphere. Some areas are like balconies (阳台)with wonderful city views. Where the rail line goes between buildings, trees are thickly planted. Other sections have wide walkways planted with wild flowers. Only the final section remains the way it has been for the last fifty years – a railway line overgrown with weeds.

　　　63. The underlined phrase “a dead weight” in Paragraph 1 means_____.

　　　A. something with potential to be better.

　　　B. something with historical interest.

　　　C. something which is a danger to people.

　　　D. something useless which slows progress.

　　　64. According to Paragraph 2, David and Hammond wanted to save the High Line because they_____.

　　　A. thought it had historical value

　　　B. wanted to reopen the train line

　　　C. thought it would bring them money 

　　　D. were interested in improving the city

　　　65.  From the last paragraph, we can learn that the park ______.

　　　A. is different in its design

　　　B. is covered with trees

　　　C. didn’t change at all

　　　D. became a natural countryside

　　　66. Which of the following is NOT true about the High Line?

　　　A. It is situated above ground level.

　　　B. Only part of the line remains.

　　　C. It is now a popular park.

　　　D. Trains still use the line.

　　Did you know that there are actually people who have paid for a flight to the moon? In the future, there will be a lot more opportunities to travel to faraway places than now… perhaps even as far as the moon. As people adventure further and further away and as planes, trains, cars, and rocket ships become faster, is it safer to have these vehicles controlled by humans or by computers?

　　While many flights by plane are controlled automatically by machines, most people today wouldn’t let their car drive itself. That’s because currently the autopilot function on your car can only keep it on the same course you are travelling on. It won’t turn the car right or left. It won’t stop if an animal jumps in the way. However, cars today can sense when something is too close and warn the driver with flashing lights and alarms. Many cars also have GPS（global positioning systems） that tell drivers which road to take and when to turn. These systems, unlike human drivers, never get lost. In the future, it is easy to believe that your car will be better able to drive itself with the aid of computers that can determine the position of your car and the speed it should travel at.

　　In addition to computers being ‘smarter’ than people regarding the best way to go or knowing how close another vehicle is, computers don’t get sick, tired, or angry. This means they won’t make the same mistakes that people make when they are not having a good day. While responding with emotion is a good thing when choosing the best way to deal with a friend’s personal problem, it may not be such a good thing when deciding what to do at the wheel of a fast-moving vehicle.

　　So what are the disadvantages of autopilot systems? Maybe one disadvantage is that a small computer problem could cause a serious accident. It could also be argued that in unexpected situations, computers might not be able to respond appropriately; some decisions require human emotions. Another problem might be that if everything were controlled by computers or robots, people wouldn’t have any jobs. 

67. What is the best title for the passage?

　　A. The Development of Autopilot

B. Technology of Future Travel 

C. A New Driving System 

D. Computerized Cars

68. Which of the following is the disadvantage of an autopilot system?

A.  It won’t make the same mistakes as people do.

B.  It can point out the best route for the driver.

C.  It might not respond properly to unexpected situations.

D. It does not have human emotions to influence its function.

69.  If some falling rocks roll down toward your car, the autopilot on your car will_______.

A. inform you of the danger 

B. turn the car right or left

C. do nothing about it

D. stop the car

70. What’s the author’s attitude towards the autopilot?

A. Approving.   B. Objective.   C. Negative.  D. Doubtful.
