It is natural that children are curious about the world around them. For example, they want to know how their hearts beat. They want to know why the ocean water tastes salty.

  As children grow up, they become curious about different kinds of things. When they are babies, they are interested in the parts of their bodies and in the smiles of their mothers. They become interested in the physical world around them: the plants, the animals, the sky. Later, they become interested in the things that people have made: wheels, bicycles, cars. And when they are adults, their curiosity continues. Sometimes this curiosity leads to a career (生涯、职业) in science.

  Scientists spend their lives trying to find out about the world.Those who work with the earth sciences study the earth, the oceans, and the skies. Other scientists who study living things work with the biological sciences. A third group of scientists study the physical sciences, e. g. physics, chemistry .

  These scientists have already discovered a lot about our world.For example, they tell us why your heart beats fast when you run. They say that when you are quiet, your heart normally beats sixty-five or seventy-five times a minute. Your heart is a pump (泵) that pumps blood to all parts of the body. The blood carries oxygen and nutrition. When you run, your muscles work very hard and use the nutrition that the blood carries to them. The muscles need oxygen, too . So your brain sends a signal to the heart. The signal means that the muscles need more nutrition and oxygen. Then the heart beats fast and sends blood quickly to the muscles. It may beat 90 to 140 times a minute.

  Of course, scientists cannot answer all of our questions. If we ask, “Why does the ocean water taste salty” scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. But then we ask , “What happens to the salt in the ocean? The ocean does not get saltier every year.” Scientists are not sure about the answer to this question.

  We know a lot about our world, but there are still many answers that we do not have, and we are curious.

     I always felt sorry for the people in wheelchairs. Some people, old and weak, can not get around by themselves. Others seem perfectly healthy, dressed in business suits. But whenever I saw someone in a wheelchair, I only saw a disability, not a person.

      Then I fainted (晕倒) at Euro Disney due to low blood pressure. This was the first time I had ever fainted, and my parents said that I must rest for a while after First Aid, I agreed to take it easy but, as I stepped towards the door, I saw my dad pushing a wheelchair in my direction. Feeling color burn my cheeks, I asked him to wheel that thing right back to where he found it.

      I could not believe this was happening to me. Wheelchairs were fine for other people but not for me, as my father wheeled me out into the main street, people immediately began to treat me differently.

      Little kids ran in front of me, forcing my father to stop the wheelchair suddenly. Bitterness set in as I was thrown back and, forth. "Stupid kids… they have perfectly good legs. Why can't they watch where they are going?" I thought. People stared down at me, with pity in their eyes. Then they would look away, maybe because they thought the sooner they forgot me the better.

     "I'm just like you!" I wanted to scream. "The only difference is you've got legs. and I have wheels. "

     People in wheelchairs are  not stupid. They see every look and hear each word. Looking out at the faces, I finally understood; I was once just like them. I treated people in wheelchairs exactly the way they did not want to be treated. I realized it is some of us with two healthy legs who are truly disabled.

Quickly, the picture comes alive with hyperlinks (超链接), offering the names of the buildings, towers and street features that appear in the photo. The hyperlinks lead to information about the history, services and context of all the features in the photo. You have just hyperlinked your reality.

That might be a little unbelievable, but the technology exists and is no fevered imagination. This is not a cool small machine invented for the next James Bond movie; this is a working technology just developed by European researchers. It could be coming to a phone near you, and soon.

This, as the marketing types say, is a game changer. It develops a completely new interface (界面) that combines web-technology with the real world. It is big and fresh, but it goes much further and has much greater influence.

    The development of the system is most outstanding because image recognition technology has long been pregnant with promise, but seemed to suffer from an unending labour.

Now MOBVIS has not only developed image recognition; it has also developed more applications for the technology; and it has adapted it to the world’s most popular technology: the mobile phone.

The MOBVIS system completely rewrites the rules for exploration and interaction with your physical environment. The system begins with panoramas (一连串景象). These panoramas form the basis of a city database. It can match buildings, towers, banners and even logos that appear in the panoramas.

A user simply takes a picture of the street feature, MOBVIS compares the user’s photograph to the panoramas and then identifies the buildings from the picture you take and the relevant links are returned.

Then you simply click on the links, using a touch-screen phone, and the MOBVIS system will provide information on the history, art, architecture or even the menu, if it is a restaurant, of the building in question.

67. Which is introduced in the passage?

A. A new game software.                                                  B. A popular mobile phone.

C. A cool small machine.                                              D. An image recognition system.

68. What can we learn about the new technology?

A. It can only be put into use on mobile phones.

B. It is a little unbelievable and just a fevered imagination.

C. It has taken an unending labor to bring the technology into our lives.

D. It will encourage the users to take more pictures of the street features.

69. What is the right order of the operation of MOBVIS?

a. A city database forms in the system.

b. MOBVIS recognizes the picture and links are returned.

c. A user touches the links on the phone screen.

d. A user takes a picture of the street feature.

e. MOBVIS provides information in question.

A. a; e; c; d; b;                         B. a; d; b; c; e            C. d; c; e; a; b                     D. c; a; e; b; d

70. From the passage, we can infer that _______.

A. MOBVIS has already been widely used all over the world

B. the writer is trying to promote the sales of the MOBVIS system

C. this new technology will soon be very popular in our lives

D. the sales of mobile phones will decrease as MOBVIS comes on market
