Bike﹣sharing has swept across China，with an increasing number of people choosing bike riding instead of driving．The bike that the service company provides has GPS or Bluetooth on it，and those bikes can be easily unlocked with a smart phone and left anywhere in public．Bike﹣sharing allows people to borrow a bike from one place and return it at another place easily．
In some cities，we can see more and more people riding this kind of sharing﹣bikes．It's very convenient to use the bikes if you have a smart phone．First，you have to download such an APP on your smart phone．Then what you need to do is to find a nearest bike through the APP，scan the QR code on the bike or connect your phone with the bike over a Bluetooth wireless connection．You will find the bike can be unlocked itself．Then you can enjoy your trip．What's more，the greatest advantage of bike﹣sharing is that you can easily find one and never worry about where to park it．The cost of riding depends on the time that you spend．Normally，every hour you ride，you need to pay one yuan．It doesn't cost so much，does it？
At the same time，some people park the bikes in their own homes．Besides，some people don't value the bikes．Now service companies are trying to solve the problem like being stolen．
Technology and science have changed our social lifestyles．We have to say bike﹣sharing brings us more convenience without doubt．And we also hope that people can not only enjoy it but also put it to good use．

When my son, Mark, was in the third grade, he saved all his pocket money for over three months to buy holiday presents. The third Saturday in December, Mark said he had made his list and had twenty dollars in his pocket.
I drove him to a nearby supermarket. Mark picked up a hand basket and went in while I waited and watched in the car. It took Mark over 45 minutes to choose his presents. Finally he came to the checkout counter and reached into his pocked for his money. It was not there! There was a hole in his pocket, but no money. Mark stood there holding his basket, tears falling down his face.
Then a surprising thing happened. A woman came up to Mark and took him in her arms. “ You would help me a lot if you let me pay for you, ” said the woman. “It would be the most wonderful gift you could give me. I only ask that one day you will pass it on. When you grow up, I would like you to find someone you can help. When you help others, I know you will feel as good about it as I do now.”

You may have noticed that the world’s population is not evenly distributed (分布) around our planet. There are more countries where people seem to be living nearly on top of each other because conditions are overcrowded . Then there are others where it seems that hardly anybody lives. What influences this unequal distribution of people ? There are specific advantages and disadvantages of living in a certain area.
The two main factors (因素) that influence people’s choice of location are climate and resources. Climate is the usual weather conditions in a region. Areas that have bad weather are generally less ideal as places to live in . The north and south poles at the top and bottom of the world may be beautiful in their rugged, natural way , but the disadvantage of the bitterly cold and windy conditions usually keeps people away. When it comes to climates, warm conditions and a normal amount of rainfall are advantages that attract people.
Natural resources are tings that we get from nature that help us survive. Each region offers different resources, and therefore attracts different groups of people. People who enjoy the beach can make their living by catching and selling the ocean’s many fish and other sea creature. Those who prefer farming can take advantage of rich soil in valleys near rivers. Some people are willing to accept the disadvantages of the terrible conditions of deserts or mountains in order to take advantages of the resources like oil or woods.The underlined part “on top of ” in the first paragraph most likely means .
| A．very close to | B．on the highest part of |
| C．in control of | D．on the surface of |
What are the main factors that influence the distribution of people ?

| A．they can’t get enough food there |
| B．the natural sights there don’t arrract people |

Why do people go and live in valleys near rives ?
| A．The temperature isn’t too low in winter. |
| B．The resources like oil can bring them much money. |
| C．People can make their living by catching and selling fish. |

I can still remember my first day at school. I was only 6 years old at that time. It was a very big room. I sat at the desk near the window, but I couldn’t see anything because the windows were too high. There was a big map of the world on the wall. But I don’t think I was worried or unhappy at that time. There was another little boy next to me. He sat there and kept quiet at first. Then he began to cry, because he didn’t want to stay there.

Since the 1970s, scientists have been searching for ways to connect the brain with computers. Braincomputer interface(BCI) technology could help people with disabilities send commands to machines.
Recently, two scientists, Jose Millan and Michele Tavella from the Federal Polytehnic School in Lausanne, Switzerland, show a small robotic wheelchair directed by a person’s thoughts.
In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts.
“Our brain has billions of body cells(细胞). These send signals through the spinal cord(脊髓) to the body part to give us the ability to move. But spinal cord injuries(脊柱受伤) or other conditions can prevent these weak electrical signals from reaching the body part.” Tavella says. “Our system allows disabled people to communicate with outer world and also to control machines.”
The scientists designed a special cap for the user. This head cover picks up the signals from the scalp(头皮) and sends them to a computer. The computer finds meanings of the signals and commands the wheelchair with an engine. The wheelchair also has two cameras that tell objects in its path. They help the computer react to commands from the brain.
Prof. Millan , the team leader, says scientists keep improving the computer software that finds meanings of brain signals and turns them into simple commands.” The practical possibilities that BCI technology offers to disabled people can be grouped in two kinds: communication, and controlling objects. One example is this wheelchair.”
He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can get advantages from. And the other is sure that they can use the technology for long. BCI is a technology that can________.
| A．help to make computer systems more modern |
| B．connect the human brain with computers |
| C．help the disabled to be healthier |
| D．control a person’s thoughts |
Which of the following shows the path of the signals described in Paragraph 5?
| A．scalp→computer→cap→wheelchair |
| B．computer→cap→scalp→wheelchair |
| C．scalp→cap→computer→wheelchair |
| D．cap→computer→scalp→wheelchair |
The team will test with real patients to_________.
| A．make money from them |
| B．prove the technology useful to them |
| C．make them live longer |
| D．learn about their physical condition |
Which of the following would be the best title for the text?
| A．Switzerland, the BCI research Center |
| B．New Findings About How the Human Brain Works |
| C．BCI Could Mean More Freedom for the Disabled |
| D．Robotic Vehicles Could Help to Cure Brain Sickness |
