We may think we're a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices (装置) well after they go out of style. That's bad news for the environment - and our wallets - as these outdated devices consume much more energy than the newer ones that do the same things.

To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life - from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use evolved since the early 1990s. Devices were grouped by generation. Desktop computers, basic mobile phones, and box-set TVs defined 1992. Digital cameras arrived on the scene in 1997. And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in 2007.

As we accumulated more devices, however, we didn't throw out our old ones." The Living-room television is replaced and gets planted in the kid's room, and suddenly one day, you have a TV in every room of the house," said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007. We're not just keeping these old devices-we continue to use them. According to the analysis of Babbitt's team, old desktop monitors and box TV's with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions(排放) more than doubling during the 1992 to 2007 window.

So what's the solution(解决方案)? The team's data only went up to 2007, but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tables instead of TVs and desktop computers could cut energy consumption by 44%.

32.What does the author think of new devices?            

A.

They are environment-friendly.

B.

They are no better than the old.

C.

They cost more to use at home.

D.

33.Why did Babbitt's team conduct the research?            

A.

To reduce the cost of minerals.

B.

To test the life cycle of a product.

C.

To update consumers on new technology.

D.

To find out electricity consumption of the devices.

34.Which of the following uses the least energy?            

A.

The box-set TV.

B.

The tablet.

C.

The LCD TV.

D.

The desktop computer.

35.What does the text suggest people do about old electronic devices?            

A.

Stop using them.

B.

Take them apart.

C.

Upgrade them.

D.

Recycle them.

I came to live here where I am now between Wounded Knee Greek and Grass Greek. Others came too, and we made these little grey houses of logs that you see, and they are square, It is a bad way to live, for there can be no power in a square.
You have noticed that everything an Indian does is in a circle, and that is because the Power of the World always works in circles, and everything tries to be round. In the old days when we were a strong and happy people, all our power came to us from the respectful circle of the nation, and so long as the circle was unbroken, the people were getting rich. The flowering tree was the living center of the circle, and the circle of the four quarters nursed it. The east gave peace and light, the south gave warmth, the west gave rain, and the north with its cold and strong wind gave strength and continuous power. This knowledge came to us from the outer world with our brief. Everything the Power of the World does is done in a circle. The sky is round, and I have heard that the earth is round like a ball, and so are all the stars. Birds make their nests in circle, for theirs are the same as ours. The sun comes forth and goes down again in a circle. The moon does the same, and both are round. Even the seasons form a great circle in their changing, and always come back again to where they were. The life of a man is a circle from childhood to childhood, and so it is in everything where power moves. Our places were like the nests of birds, and these were always set in a circle, the nation’s circle, a nest of many nests, where the Great Spirit meant for us to nurse our children.
But the Wasichus (Indian word for “white people”) have put us in these square boxes. Our power is gone and we are dying, for the power is not in us any more. You can look at our boys and see how it is with us. Where we were living by the power of the circle in the way we should, boys were men at twelve or thirteen years of age. But now it takes them very much longer to be full - grown.

Listen carefully, working people, we would like to tell you something that could save your precious time and money! Best of all, it is free!
It’s “no”.
What do you ask? We’ll say it again: “No”.
Sweet and simple “no”.
Say “no” at your office and see how quickly that pile of work on your desk disappears.
“Saying ‘no’ to others means you are saying ‘yes’ to yourself, ” said Leslie Charles, a professional speaker from East Lansing, Michigan.
“Time is precious. People are spending money buying time. And yet we are willing to give up our time because we can’t say ‘no’.”
Susie Watson, a famous writer, said people who always say “yes” need to say “no” without guilt(内疚)or fear of punishment. “I would rather have someone give me a loving ‘no’ than an obligated(强制的) ‘yes’, ” she said.
Susie Watson says she feels “no” obligation to give an explanation when she says “no” either socially or professionally. Does she feel guilty about it? “Not at all, ” said Watson, who is director of advertising and public relations at Timex Corp in Middlebury, Connecticut. “Most people are afraid of saying ‘no’advice is to say ‘yes’ only if you don’t mean ‘no’.” Watson said “no” is the most effective weapon against wasting time. “Every year there are more demands on your time… Other people are happy to use up your time, ” Watson said. Time saving appears to be “no’s” greatest friend.
“No” can be your new friend, a powerful tool to take back your life. “No” may even take you further in the business world than “yes”.
“No” is power and strength. “No” now seems completely correct. “Saying ‘no’ isn’t easy. But finally it’s greatly liberating,” Charles said. But, he added, a “no” project needs to be worked on every day because it is hard to change long-term habit.
But, he also warns: “Don’t go to extremes. Don’t find yourself saying ‘no’ to everything. In return you should learn to hear ‘no’.”
.

A.you can have more time to play with others

.
When you say “no” to others you should say it in a _______.

A.secret way   B.polite way
C.proud way D.guilty way

.

A.they say “no” at a suitable time
B.they say “no” as much as possible
C.they are afraid of saying “no”
D.they make others angry at them

Jeanne Calment, a French woman, became a record breaker on 17 October of 1995, when at the age of 120 years and 238 days, she became the longest-lived human being on record. A Japanese man died in 1986 at the age of 120 years and 237 days.
Jeanne Calment lives in a small old people’s home in the south of France; her husband, her only child and her grandson have all died. She is nearly blind and deaf and is always in a wheelchair, but her doctor describes her as being more like a 90-year-old in good health than someone of 120. She still has a lively sense of humor. When asked on her 120th birthday what she expected of the future, she replied: A very short one. She also remarked that she thought the good Lord had forgotten all about her.
So what is the key to a long life? According to some doctors, diet, exercise and no smoking are the three important factors. Jeanne Calment has followed two of the tips. She has always eaten a healthy diet, and she used to do exercises every day until she broke her leg at the age of 115. However, until recently she drank two glasses of strong red wine a day, and she does smoke (now only a little). Besides, Jeanne Calment might have got very good genes(基因) from her parents. Her father lived to the age of 94 and her mother to 86.
A local lawyer bought her house when she was 80 under an agreement that he would pay her some money every year until her death. It must have seemed a good move at the time, but so far the lawyer has paid her at least three times the value of the house. Every year on her birthday Jeanne Calment sends him a card saying:
Sorry, I’m still alive!
.
. How does Jeanne Calment feel about her old age?

A.She is miserable and unhappy.
B.She is cheerful and humorous.
C.She would like to live much longer.
D.She feels she is going to die very soon.

.
Jeanne Calment owes her good health and long life to _______.

A.smoking only a little every day
B.her giving up smoking and drinking
C.drinking two glasses of strong red wine every day
D.the good genes from her parents, a healthy diet and some exercises

.
. Which of the following could best replace the word “move” in the fourth paragraph?

A.deal B.trick C.march D.sport

.
. Why does Jeanne Calment say “Sorry, I’m still alive” to the local lawyer every year on her birthday?

A.Because she had an agreement at 80 with the lawyer which was to her advantage.
B.Because she has asked the lawyer to pay her more rent than they first agreed.
C.Because the lawyer has paid her much more money than the value of the house.
D.Because the house she sold to the lawyer isn’t worth the money he has already paid.

Researchers have found more evidence that suggests a relationship between races and rates(率) of lung cancer among smokers. A new study shows that black people and Native Hawaiians are more likely to develop lung cancer from smoking. It compared their risk to whites, Japanese-Americans and Latinos.
Researchers at the University of Southern California and the University of Hawaii did the new study. The New England Journal of Medicine published the findings. The eight-year research studied more than 180,000 people. They included present and former smokers and people who never smoked. Almost 2.000 people in the study developed lung cancer.
Researchers say genetics(遗传学) might help explain the racial and ethnic(种族的) differences. There could be differences in how people's bodies react to smoke. But environmental influences, including the way people smoke, could also make a difference.
African-Americans and Latinos in the study are reported smoking the fewest cigarettes per day. Whites are the heaviest smokers. But the scientists point out that blacks have been reported to breathe cigarette smoke more deeply than white smokers. This could fill their lungs with more of the chemicals in tobacco that cause cancer.
Scientists know that some diseases effect different groups differently. And some drug companies have begun to develop racially targeted(针对) medicines. Last June, the United States Food and Drug Administration approved a drug designed to treat heart failure in black patients. The name is BiDil. The agency called it "a step toward the promise of personalized medicine."
Which of the following orders is from higher to lower risk of having lung cancer?

A.Whites—Native Hawaiians B.Africans—Americans—Latinos
C.Asians—Native Hawaiians D.Africans—Americans—Native Hawaiians

Researchers agree that it is that may probably determine black people’s risk of lung cancer.

A.the larger amount of smoking than white people
B.the living style or habit of the blacks
C.the depth of cigarette smoke into their lungs
D.the physical strength to react to cigarette smoke

People in the new study are made up of .

A.heavy smokers in America B.the black and white people
C.the Asians and Hawaiians D.smokers and non-smokers

The production of BiDil referred to in the last paragraph is to .

A.explain different races react to some diseases differently
B.tell the readers that racial differences exist in smokers
C.show a big step people have taken in the medicine area
D.support the idea that it is easy for blacks to have cancers

Which of the following statements is TRUE according to the author?

A.The way of smoking may increase the risk of lung cancer.
B.Race has nothing to do with the risk of having a lung cancer.
C.The research was started by the New England Journal of Medicine.
D.The risk of lung cancer lies I how much a person smokes.
