暑假作业北京艺术与科学电子出版社系列答案
第三学期赢在暑假系列答案Televisions, stereos, telephones, and computers have changed the way we spend our time and what we know about the world. Some of the changes brought about by these material possessions have improved our way of life, but others have made it worse. Our young teenagers turn on the television, play the stereo, play games on the computer, talk on the telephone, and eat all the same time. This drives me right up the wall to instant insanity(精神失常).
However, teens of today place too great an importance on material property. They spend an average of several hours a day watching television, listening to stereos, playing on the computer, playing video games, and talking on the telephone. Families no longer watch television together and there is great lack of communication. Materialism is evident when an otherwise intelligent teenager drives their parents crazy, and into debt, when misusing communication equipment. Teens judge and admire other teens for what they own and have, rather than for what they are or what they can do. They no longer care about values, like honesty, integrity(正直), freedom, talent, quality and other values and morals.
However, good or bad, communication devices are here to stay. It is up to us, as parents, to stop our beloved teenagers from misusing and abusing our communication equipment and devices. We need to avoid the problems they present and to make the most of their opportunities they possess and hold for us all.
1.The writer’s attitude toward the modern material possessions is generally _____.
|
A．positive |
B．negative |
C．neutral |
D．indifferent |
2.According to the writer, teens’ overuse of communication equipment can do harm to _____.
|
A．their own health |
B．their own study |
|
C．their own morality |
D．their neighbors’ life |
3.The writer attributes (归咎) the unsatisfactory behavior of teens to _____.
|
A．teens’ too much free time |
B．parents’ non-interference |
|
C．inadequate school education |
D．material property |
4.It can be inferred from the passage that the writer seems to be most annoyed at ______.
|
A．all the modern material possession |
B．eating while talking on the phone |
|
C．the decline in teens’ morality |
D．all the communication equipment |
Futurologists predict that life will probably be very different in 2050.
TV channels will have disappeared. Instead, people will choose a program from a “menu” and a computer will send the program directly to the television. Today, we can use the World Wide Web to read newspaper stories and see pictures on a computer thousands of kilometers away. By 2050, music, films, programs, newspapers, and books will come to us by computer.
Cars will run on new, clean fuels and they will go very fast. Cars will have computers to control the speed and there won’t be any accidents. Today, many cars have computers that tell drivers exactly where they are. By 2050, the computer will control the car and drive it to your destination. Space planes will take people halfway around the world in 2 hours. Today, the United States Space Shuttle can go into space and land on Earth again. By 2050, space planes will fly all over the world and people will fly from Los Angeles to Tokyo in just 2 hours.
Robots will have replaced people in factories. Many factories already use robots. Big companies prefer robots — they don’t ask for pay rises or go on strike, and they work 24 hours a day. By 2050, we will see robots everywhere — in factories, schools, offices, hospitals, shops and homes.
Medical technology will have conquered many diseases. Today, there are devices（设备）that connect directly to the brain to help people hear. By 2050, we will be able to help blind and deaf people to see and hear again.
Scientist will have discovered how to control genes（基因）. Scientists have already produced clones of animals. By 2050, scientists will be able to produce clones of people, and decide how they look, how they behave and how clever they are. Scientists will be able to do these things, but should they?
1.We can learn from the passage that some big companies prefer robots to human workers, because human workers __________.
|
A．often ask for more pay |
|
B．can work 24 hours a day |
|
C．are not clever enough |
|
D．are often late for work |
2.The underlined word “conquered” in Paragraph 5 most probably means ________.
|
A．discovered |
B．treated |
C．caused |
D．cured |

|
A．few diseases will attack people by 2050 |
|
B．there will be no blind and deaf people by 2050 |
|
C．medical technology will be more effective by 2050 |
|
D．devices are connected directly to the brain to help people hear |
