At present, we can use computers or smart phones to text messages to the friends around the world. We can buy fruit from Brazil or see movies made in India on the websites. But how can we get to know and understand people who are living in different countries better?

As we all know, it is beneficial for teenagers to have more knowledge and understand the world better. We must remember that they are the decision-makers of the future. To shape the world in the interests of all, we should help them to act as responsible global citizens (公民). So it is important for them to learn more about how other people live in different parts of the world. By doing this, they can find out what problems they have in their communities and decide how they can help each other better.

A charity (慈善) group in the UK started a project for Africa in February, 2004. The aim of the project was to take a fresh look at Africa's past and present and the international community's role in its development. Lots of British students took part in the project. Students from 25 UK schools connected with students from 25 African schools to discuss the African Continent (非洲) and its culture on the Internet. Some students from the poor areas in Africa were taken to the places that had computers, so they could take part in the project. Students used their computers to work on the Internet and send emails. They could even design their own web pages with pictures, sounds and videos. Together the teenagers built a website which went live in June, 2005. Through the project teenagers were encouraged to study the different cultures of Africa as well as some of the problems facing young people in Africa.

Now, more and more projects have been started since then all around the world. Teenagers from schools in different countries are still trying to make connections and find out more about each other. Let's hope these projects help teenagers understand more about the lives of others on the other side of the world.

A.use computers as often as possible in their free time

It seems like technology is everywhere. Computers and smart phones are at the center of almost everything we do. They constantly (持续地) require our attention. We text our friends with them during the day, sleep with them by our beds and check our messages as soon as we wake up.

In the future, technology will no longer be interrupting us all the time. Instead, we will use calm technology which was first developed by scientist Mark Weiser in the 1970s. In his opinion, calm technology works quietly but constantly. We know it is there, but we don’t pay much attention to it. According to Mark, the best technology should be invisible (隐形的) and let you live your life.

We already use many different types of calm technology in our everyday lives. Do you have a smoke alarm (警报器) in your house? That smoke alarm is always there, checking the air for smoke and quietly keeping you safe. It only reminds you it’s there when you’ve burnt your bread! Or there may be lights in your home or school. When somebody passes in front of their sensors (传感器), the lights turn on. You don’t think about this type of technology until you see the light go on.

In the future, we can use calm technology to open the curtains (窗帘) for us in the morning, to turn down the heat when we leave, or even to choose the best music for us. The minute we walk through the door, our house will turn on the lights and music, and perhaps even start to prepare our dinner!

1.Which of the following is an example of calm technology?

A. A computer. B. A smart phone. C. A smoke alarm. D. A radio.

2.What does the underlined word “interrupting” mean?

A. Hurting. B. Protecting. C. Helping. D. Troubling.

3.What’s the main idea of the third paragraph?

A. Calm technology keeps us safe in many ways.

B. Calm technology can help you to do housework.

C. Calm technology has been used in our daily lives.

D. Calm technology plays an important part in schools.

4.What can’t we learn from the last paragraph?

A. We can use it to open the curtains in the morning.

B. We can use it to turn down the heat when we leave.

C. We can use it to choose the best music.

D. We can use it to wash dishes.

5.What can we infer from the passage?

A. The light won’t go on unless we touch the sensor.

B. Calm technology will make our life more convenient.

C. People will depend more on smart phones in the future.

D. People won’t have to work because of calm technology.

Technology is everywhere. Computers and smart phones are at the center of almost everything we do. We text our friends during the day, sleep with our devices by our beds and check our messages as soon as we wake up.

In the future, technology will no longer interrupt(打断) us all the time. Instead, we will use calm technology—it was first developed by scientist Mark Weiser in the 1970s.

Calm technology works quietly without stopping, at the edge of our attention. We know it is there, but we don't focus on it. According to Mark, the best technology should be invisible(无形的) and let you live your life.

We already use many different types of calm technology in our everyday lives. A smoke alarm checks the air for smoke and quietly keeps you safe. It only reminds you it's there when you've burned your toast! There may be lights at home or school that are sensitive to movement. When somebody passes by their sensor(传感器), the lights turn on. Even a microwave oven is an example of calm technology. You're not standing at the stovetop heating your food: the microwave is doing it for you.

In the future, our houses will use calm technology to do a lot of things. For example, open the windows for us in the morning, turn down the heat when we leave, or even choose the best music for us. When we walk into the door, our house will turn on the lights, set the heater, and prepare for our dinner!

九年级英语单选题中等难度题查看答案及解析

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.

1.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

2.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

3.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

4.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
