閱讀理解:  閱讀下列短文，從每題所給的A、B、C和D項中，選出最佳選項。

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

科目：高中英語 來源：2014屆江西南昌二中高二下期第二次月考英語卷（解析版） 題型：閱讀理解

The air bag is a piece of safety equipment in cars. It was first designed by John W. Hetrick in 1952. Like many inventions, he came up with the idea as a result of an event that had occurred in his life. He says:

“In the spring of 1952, my wife, my seven-year-old daughter, Joan, and I were out for a Sunday drive in our 1948 Chrysler Windsor. About three miles outside Newport we were watching for deer jumping across the road. Suddenly, there was a large rock in our path. I hit the brakes and we went into a ditch(壕溝).

“As I applied the brakes, both my wife and I threw our hands up to keep our daughter from hitting the car. There was soft mud in the ditch, so the car wasn’t damaged, and no one was hurt.”

“During the ride home I couldn’t stop thinking about the accident. I asked myself,‘Why couldn’t some object come out to stop you from striking the inside of the car?’As soon as I got home that night I drew some sketches(草圖). Each evening for the following two weeks, I’d add or reduce something from the sketches.”

Hetrick applied an event he had observed while in the Navy to the design of the air bag. He was repairing a torpedo(魚雷) which had a cloth covering. When the compressed（壓縮的） air that was in the torpedo was let out, the covering was suddenly filled with air and was shot to the ceiling.

With this knowledge, he developed his design until he was able to obtain a patent on the invention on August 5, 1952. The idea was similar to the air bag designs of today. Compressed air is stored in a container and when a traffic accident occurs and the car slows down at a rapid enough rate, the air will be released into the air bag. The idea was ingenious, but Hetrick’s air bag never would have functioned properly. It was really a breakthrough, but it would require years and years of designing and testing by some top car designers before it could be used.

1.The car accident Hetrick was involved in ________.

A．damaged his car                        B．happened in 1948

C．was caused by a deer                    D．caused no harm to his family

2.Hetrick’s experience in the Navy________.

A．turned out to be dangerous               B．was helpful to his invention

C．involved designing torpedoes              D．inspired him to design an air bag

3.The underlined word “ingenious” in the last paragraph is closest in meaning to _______.

A．creative          B．ridiculous         C．crazy             D．complex

4.What do we know about the air bag Hetrick designed?

A．It came into use in the 1950s.              B．It performed perfectly in car accidents.

C．It prepared the way for air bags nowadays.    D．It took Hetrick about two months to develop it.

5.The text is mainly about ____.

A．the great inventor Hetrick                 B．The invention of air bags

C．a(chǎn) terrible car accident                    D．road safety in the 1950s
