carbon “footprint”.That footprint reflects the amount of carbon dioxide that is emitted(排放)into the atmosphere as a result of someone’s daily activities.Carbon footprints tend to be low for city dwellers(城镇居民).Living in a suburb outside a city, however, can turn that footprint into a bootprint.
Energy researchers Christopher Jones and Daniel Kammen calculated carbon footprints for people in every zip code across the United States.People living in city centers had small footprints, the researchers found.“It is much easier to have a low carbon impact if your home is close to where you work, shop and play,” explains Jones.Living within walking or biking distance cuts back on the amount of carbon dioxide associated with moving people by cars.And cities with extensive bus and subway networks allow people to travel great distances while keeping releases of climate-altering greenhouse gases low.
Not everyone can afford to live in the city, however.And not everyone wants to.Rings of suburbs have popped up around major cities across the world.Suburbs offer more space, allowing people to build larger homes.Suburbs may offer better schools for a family’s kids.But those homes are typically well beyond walking distance from where their owners work, play or learn.So people who live in suburbs often drive long distances.
The new findings are an important contribution to climate research, says Matthew Kahn, an environmental economist at the University of California, who was not involved with the study.Kahn would like to see the analysis applied to other parts of the world — Europe, India and China, for instance.That would give scientists a better feel for how culture might mix with location to influence our carbon footprints.
21.“Footprint” refers to the amount of carbon dioxide released by ______.
A.an industry
B.an individual
C.a region
D.a country
22.What is the new finding concerning the footprints of people living in cities and those living in suburbs?()
A.The two are not at all comparable
B.The former are higher than the latter
C.The latter are higher than the former
D.The former are similar to the latter
23.What is the key factor mentioned to explain the new findings?()
A.Distance travelled by cars
B.Spending habits
C.Size of families
D.Attitude towards energy saving
24.What does Matthew Kahn think of the new findings?()
A.He is confused by the mixed messages
B.He thinks highly of them
C.He can easily understand them
D.He doubts their validity
25.What is the purpose of the author in writing the passage?()
A.To call on people to reduce carbon footprints
B.To offer tips on how to live a low-carbon life
C.To clear up misunderstandings about carbon emission
D.To introduce the research on carbon footprints

Psychologists now believe that noise has a considerable effect on people's attitudes and behavior. Experiments have proved that in noisy situations(even temporary ones), people would have more anger and less cooperation; In more permanent noisy situations, many people cannot work hard, and they suffer from severe anxiety as well as other psychological problems. Some researchers, who study various aspects of effect of noise in people's mental life, maintain that noise, either temporary noise or permanent noise, often destroy creativity and activity by disturbing people's emotion and make them more easily annoyed and hard to cooperate.
However, psychologists distinguish between "sound" and "noise". "Sound" is measured physically in decibels(分贝). "Noise" cannot be measured in the same way because it refers to the psychological effect of sound and its level of "intensity" depends on the situation. Thus, for passengers at an airport who expect to hear airplanes taking off and landing, there may be a lot of sound, but not much noise(that is, they are not bothered by the noise). By contrast, if you are at a concert and two people behind you are whispering, you feel they are talking noisily even if there is not much sound. You notice the noise because it affects you psychologically.
Both sound and noise can have negative effects, but what is most important is if the person has control over the sound. People walking down the street with earphones, listening to music that they enjoy, are receiving a lot of decibels of sound, but they are probably happy hearing sounds which they control. On the other hand, people in the street without earphones must tolerate a lot of noise which they have no control over. It is noise pollution that we need to control in order to help people live more happily.
According to the passage, people () .
A.can not complete his work in a noisy situation
B.will suffer from complete deafness because of noise pollution
C.can be psychologically affected by working in very noisy factories
D.may cooperate well in a noisy surrounding

(课外选材)
When computer servers operate a complex program, they can get very hot. Cooling the servers can be costly. So researchers asked what would happen if the heat created by the servers could be captured and used?
Data centers of large Internet companies such as Google and Microsoft have thousands of computer servers. As these servers process information, they create large amounts of heat, so they need huge cooling systems. These systems send the heat into the air. The Dutch company Nerdalize thinks paying for electricity to operate the servers and then paying again to cool them is a waste of energy. So it developed a device called the e-Radiator. It is a computer server that also works as a heating source. Boaz Leupe is the chief executive officer of Nerdalize. He says the e-Radiator saves money because companies don't have to pay to cool their servers.
"The kilowatt(千瓦)hour you are using is used twice -- once to heat the home and once to compute the client's task without the cooling overhead." He says five homeowners in the Netherlands are testing the heating device in their homes. "We reimburse the electricity the server uses, and that we can do because of the computer clients on the other side, and, in that way, homeowners actually get heating for free, and computer users don't have to pay for the overhead of the data center.
Jan Visser is one of the participants in the year-long experiment. He says the amount of heat produced by the e-Radiator depends on the work being done by the computer server. He says it cannot be used as the primary source of heat. But he is ready to try it.
He says if it provides enough warmth, he will be able to use his home's heating system less, which will save him money. Nerdalize says e-Radiators create heat temperatures of up to 55℃. It says the devices could save users up to $440 in heating costs a year.
1.Why did researchers ask what would happen if the heat created by the servers could be captured and used?{A; B; C}
A. Because computers can get very hot.
B. Computer servers is a complex program.
C. Cooling computer servers costs a lot of money.
2.The computer servers in large Internet companies such as Google and Microsoft can {A; B; C}.

3. Nerdalize developed the e-Radiator because {A; B; C}.
A. e-Radiator cost less energy
B. e-Radiator can cool the servers for free
C. e-Radiator can create cold air for free
4.According to Jan Visser, the amount of heat produced by the e-Radiator {A; B; C}.
A. depends on the work being processed by PC
B. cannot be used as the home's heating system
C. cannot be used as the main source of heat
5.The best title for this passage is {A; B; C}

College Night Owls Have Lower Grades
College students who are morning people tend to get better grades than those who are night owls (晚睡的人), according to University of North Texas researchers.
They had 824 undergraduate(大学本科生的) students complete a health survey that included questions about sleep habits and daytime functioning, and found that students who are morning people had higher grade point averages (GPAs) than those who are night people.
"The finding that college students who are evening types have lower GPAs is a very important finding, sure to make its way into undergraduate psychology texts in the near future, along with the research showing that memory is improved by sleep," study co-author Daniel J. Taylor said in a prepared statement.
"Further, these results suggest that it might be possible to improve academic
performance by using chronotherapy (时间疗法) to help students retrain their biological clock to become more morning types," Taylor said.
The research was expected to be presented Monday at SLEEP, the annual meeting of the Associated Professional Sleep Societies, in Baltimore.
In other findings expected to be heard at the meeting, University of Colorado
researchers found a significant association .between insomnia (失眠) and a decline in college students' academic performance.
The study included 64 psychology, nursing and medical students, average age 27.4 years, who were divided into two groups - low GPAs and high GPAs.
Among those with low GPAs, 69.7 percent had trouble falling asleep, 53.1 percent
experienced leg kicks or twitches (痉挛) at night, 65.6 percent reported waking at night and having trouble falling back to sleep, and 72.7 percent had difficulty concentrating during the day.
"In college students, the complaint of difficulty concentrating during the day continues to have a considerable impact on their ability to succeed in the classroom," study author Dr James F. Pagel said in a prepared statement. "This study showed that disordered sleep has significant harmful effects on a student's academic performance, including GPAs."
41 In the first study, students who stay up late
A had lower GPAs
B had higher GPAs.
C performed equally well in their studies.
D had little difficulty concentrating during the day

A few years ago a young mother watched her husband diaper(给...换尿布) their firstborn son. "You don't have to be so unhappy about it," she protested. "You can talk to him and smile a little." The father, who happened to be a psychologist, answered firmly, "He has nothing to say to me, and I have nothing to say to him."
Psychologists now know how wrong that father was. From the moment of birth, a baby has a great deal to say to his parents and they to him. But a decade or so ago, these experts were describing the newborn as a primitive creature who reacted only by reflex, a helpless victim of its environment without capacity to influence it. And mothers accepted the truth. Most thought(and some still do) that a new infant could see only blurry shadows, that his other senses were undeveloped, and that all he required was nourishment, clean diapers, and a warm bassinet.
Today university laboratories across the country are studying newborns in their first month of life. As a result, psychologists now describe the new baby as perceptive, with remarkable learning abilities and an even more remarkable capacity to shape his or her environment—including the attitudes and actions of his parents. Some researchers believe that the neonatal period may even be the most significant four weeks in an entire lifetime.
Far from being helpless, the newborn knows what he likes and rejects what he doesn't. He shuts out unpleasant sensations by closing his eyes or averting his face. He is a glutton for novelty. He prefers animate things over inanimate and likes people more than anything.
When a mere nine minutes old, an infant prefers a human face to a head-shaped outline. He makes the choice despite the fact that, with delivery-room attendants masked and gowned, he has never seen a human face before. By the time he's twelve hours old, his entire body moves in precise synchrony to the sound of a human voice, as if he were dancing. A non-human sound, such as a tapping noise, brings no such response.
The author points out that the father diapering his firstborn son was wrong because ______.
A.he thought the baby didn't have the power of speech
B.he believed the baby was not able to hear him
C.he was a psychologist unworthy of his profession
D.he thought the baby was not capable of any response
