2 . THREE CENTURIES OF HOAXES!
A THINKING MACHINE
In 1769, long before computers were invented, a man from Hungary (匈牙利) built a wonderful machine that could play chess very well. It pleased people all over Europe and beat nearly everyone who played chess with it. For decades, many people believed that it was truly a thinking machine. About 85 years later, the secret was finally revealed. There was a man hiding inside the machine all the time, who was obviously very good at playing chess!
ZOO ESCAPE (逃脱)
On November 9, 1874, a New York newspaper ran a shocking story on its front page. It said that all the animals in the Central Park Zoo had escaped and were running around the city. It said the police were working to save people, but 27 people had already been killed, and 200 people were hurt. Many people in New York were terrified. But it was all just a hoax. The story was made up by Thomas Connery, an editor at The Herald, who wanted to draw attention to the poor condition of cages in the zoo.
ROSIE THE RUNNER
The first woman to cross the finish line of the 1980 Boston Marathon (马拉松) was 23-year-old Rosie Ruiz. However, as she received her prize, people started to doubt that. She didn’t seem to be tired at all. What’s more, none of the other runners remembered seeing her in the race. Later, it turned out that she had run only half a mile (about 805 meters) and taken the train for the rest of the race! Her prize was taken away, of course.

5 . Today there are 6 billion people on the Earth. By the year 2050, there may be 12.5 billion. There are a lot of people to feed. We need more food.
One way to produce more food is by growing stronger plants. For thousands of years, farmers have made plants better. Every season, they pick the best plants for the next season. It works very slowly. Since 1983, scientists have been able to change plants more quickly by changing their genetic material(遗传物质). Foods from plants grown in this way are call genetically modified foods(转基因食品), or GM foods.
By changing the genetic material of a plant, it is possible to make new plants. They make plants strong against plant diseases. They can also help in our diseases: a kind of rice is being prepared, for example, which stops people from becoming blind.
Rich countries produce GM foods because they are easy to grow and bring in more money. Poor countries are interested in them because they help produce more food.
GM plants are not natural. No one knows how good or bad they are. Making GM foods is only one way of feeding people in 2050. There are strong feelings against them, because the are unnatural. They may feed people, and then hurt them or their children later. But, both rich and poor countries are very interested in their use, and they are not going away. In 2050, we may think differently about them.
1. GM foods are made by ________.A.farmers | B.workers | C.scientists | D.plants |
A.They make plants strong against diseases. | B.They are unnatural. |
C.They can help in human diseases. | D.Both A and C. |

C.are safe | D.are grown only in rich countries |
A.They are not useful. | B.They are not helpful. |
C.They are not natural. | D.They are not cheap. |
A.GM foods will disappear one day in the future |
B.GM foods will not disappear in the future |
C.people will not be interested in GM foods |
D.people will have to stop using GM foods |
6 . Imagine a world where air pollution is no longer a problem. Clean air is all around us. People don’t have to worry about polluting the air 164 every time they drive their cars. They no longer need to face the problem of not having enough fuel either.
Although scientists have been trying for many years to develop a new kind of car that does not need gasoline (汽油), they have been unsuccessful. Recently, however, car engineers have succeeded in creating a new kind of car that runs on gasoline and electricity. This is the famous hybrid car. This car gets its name from the fact that it has a gasoline engine (引擎) and an electric motor inside. Hybrid cars do not pollute the environment as much as the cars that are commonly used today. They also cost drivers less money because they need less fuel than ordinary cars.
Hybrid cars are becoming widely popular in the United States. They are soon expected to become widely used around the world. If scientists and engineers continue to work on car development, perhaps the world with clean air that we imagined earlier just might become real in the future.
1. The underlined word “they” in Paragraph (段落) 2 means ________.A.cars | B.drivers | C.engines | D.scientists |
A.increase air pollution | B.run only on electricity |
C.have no engines inside 165 | D.need less fuel than ordinary cars |

7 . Common Sense Media did a study about kids and technology(科技). It was about many different kinds of activities, from reading and listening to the radio, to new favorites like using social media users (社会媒体用户) and video chatting(视频聊天). More than 2,600 kids took part in the study. Here are some truths:
Truth 1: Some children spend too much time looking at screens(屏幕).
One in five children uses more than six hours of computers each day, and 18% of children are looking at their screens for more than 10 hours a day. But children spend only 30 minutes reading every day.
Truth 2: Boys prefer video games; girls prefer social media.
Among boys, 71% enjoy playing video games, twice as many as girls. Girls spend about 40 minutes more each day on their screens than boys do.
Truth3: Music is their favorite.
For children, while 57% have TV sets in their rooms, music is their favorite. However, only about a third listen to music on the radio. Most children listen to it on their smartphones(智能手机).
Truth 4: Gamers get out less and less.
For gamers, their play time is the least, only 47 minutes every day. Social media users are the most active, spending one hour and 13 minutes every day doing sports.

Their teacher, Will Whitney, said the kids were learning problem-solving. “Kids meet a problem and think of different ways to solve it,” said Whitney. Like a lot of the teachers at the camp, Whitney attended iD Tech camp while growing up. As a kid, he loved video games. He loved the camp so much that he had

9 . The Internet is shaping our lives. We already have online shopping services and mobile payment. However, this is just a start. The world’s leading tech companies are planning to build smarter online communities.
The company Alibaba uses AI technology in its unmanned supermarket in Wuzhen. There is no salesperson in the supermarket, just a tablet on a desk that says “please smile”.
There is also AI that can read lips.
These technologies are being put into wider use. We may see a smarter world and better lives in the near future.
