題目列表(包括答案和解析)

閱讀理解:  閱讀下列短文,從每題所給的A、B、C和D項(xiàng)中,選出最佳選項(xiàng)。

Imagine you’re at a party full of strangers. You’re nervous. Who are these people? How do you start a conversation? Fortunately, you’ve got a thing that sends out energy at tiny chips in everyone’s name tag (標(biāo)簽). The chips send back name, job, hobbies, and the time available for meeting-whatever. Making new friends becomes simple

This hasn’t quite happened in real life. But the world is already experiencing a revolution using RFID technology.

An RFID tag with a tiny chip can be fixed in a product, under your pet’s skin, even under your own skin. Passive RFID tags have no energy source-batteries because they do not need it. The energy comes from the reader, a scanning device, that sends out energy (for example, radio waves) that starts up the tag immediately.

Such a tag carries information specific to that object, and the data can be updated. Already, RFID technology is used for recognizing each car or truck on the road and it might appear in your passport. Doctors can put a tiny chip under the skin that will help locate and obtain a patient’s medical records. At a nightclub in Paris or in New York the same chip gets you into the VIP (very important person) section and pays for the bill with the wave of an arm.

Take a step back:10 or 12 years ago,you would have heard about the coming age of computing. One example always seemed to surface: Your refrigerator would know when you needed to buy more milk. The concept was that computer chips could be put everywhere and send information in a smart network that would make ordinary life simpler

RFID tags are a small part of this phenomenon. “The world is going to be a loosely coupled set of individual small devices, connected wirelessly,” predicts Dr.J.Reich. Human right supporters are nervous about the possibilities of such technology. It goes too far tracking school kids through RFID tags, they say. We imagine a world in which a beer company could find out not only when you bought a beer but also when you drank it. And how many beers. Accompanied by how many biscuits. w*w*When Marconi invented radio, he thought it would be used for ship-to-shore communication. Not for pop music. Who knows how RFID and related technologies will be used in the future. Here’s a wild guess: Not for buying milk.

1. The article is intended to______.  

A. warn people of the possible risks in adopting RFID technology

B. explain the benefits brought about by RFID technology

C. convince people of the uses of RFID technology

D. predict the applications of RFID technology

2. We know from the passage that with the help of RFID tags, people        .

A. will have no trouble getting data about others

B. will have more energy for conversation

C. will have more time to make friends

D. won’t feel shy at parties any longer

3. Passive RFID tags chiefly consist of        .

A. scanning devices          B. radio waves   C. batteries                  D. chips

4. Why are some people worried about RFID technology?

A. Because children will be tracked by strangers.

B. Because market competition will become more fierce.

C. Because their private lives will be greatly affected.

D. Because customers will be forced to buy more products.

5. The last paragraph implies that RFID technology        .

A. will not be used for such matters as buying milk

B. will be widely used, including for buying milk

C. will be limited to communication uses

D. will probably be used for pop music

A

  Ask Dr ? Jeffers

This month Dr. Jeffers is answering questions about the human brain and how it works.

Dear Dr. Jeffers,

One of my colleagues, Felix Moeller, told me that scientists are learning to use computer to ‘read minds’. Is there any truth to this story/

Jane Leon, New York, USA

Dear Ms. Leon,

Well, a lot of research is being conducted in this area, but so far, the brain scanning equipment and corresponding computer programs haven’t been able to actually read thoughts. In one experiment, test subjects(受試者)were connected to scanning equipment and shown two numbers on a screen. They were then asked to choose between adding or subtracting(減)the two numbers. Using this method, researchers were able to follow brain processes and make the correct assumptions(假設(shè))70 percent of the time. It’s not quite mind reading, but it’s certainly a first step.

—Dr. J.

Dear Dr. Jeffers,

My three-year-old son loves it when I dig my fingers into his sides and tickle (胳肢)him until he laughs uncontrollably. The other day I noticed him trying to tickle himself but he couldn’t do it. Why not?

Glenn Lewis, Vancouver, Canada

Dear Mr. Lewis,

It’s because of how the brain works. The brain is trained to know what to pay attention to and what to ignore. It causes us to ignore physical feelings we expect to happen, but it causes a mild panic reaction when there is an unexpected feeling. For example, you don’t notice how your shoulder feels while you’re walking down the street. But if someone comes up behind you and touches you lightly on the shoulder, you may jump in fear. It’s that unexpected part that causes the tickle reaction.

Dr. J.

46. What can we learn from the answer to the first question?                          

A. Some equipment is able to read human minds.

B. Some progress has been made in mind reading.

C. Test subjects have been used to make decisions.

D. Computer programs can copy brain processes.

47. People laugh when tickled by others because the feeling is _______.                 

A. unexpected        B. expected        C. comfortable        D. uncomfortable

48. Who has got a little child according to the text?                                  

A. Ms. Leon          B. Mr. Lewis        C. Mr. Moeller        D. Dr. Jeffers

49. According to the text, Jeffers is probably _______.                               

A. a computer programmer                B. a test subject

C. a human brain expert                   D. a medical doctor
