When it comes to the world of computers, green computing is becoming popular. But what is green computing?
The term “green computing” is one that is being used in many different markets and areas all over the world in today’s global technology. However, many computer users aren’t sure what it means. Green computing is actually quite easy to explain and to do—it is basically learning to use computer resources more efficiently to protect the environment as well as saving energy. The main goal is to reduce the use of energy and materials that harm the environment.
Green computing started as early as 1992, when the EPA created Energy Star program that improved computing equipment and technologies. Because of this program sleep pattern appeared and many computer users began to adopt this policy to help save energy when they were not using their computers. In October of 2006, Energy Star made the requirements stricter for computers. Because of these new requirements, there are over 20 states that have now set up a special recycling program for old computers to help with green computing.
Many of today’s IT systems are beginning to rely on both people and hardware to help push their computer systems toward a more green computing system to help both the company and others. This is a hard balance to achieve, as it has to satisfy users. Many companies are learning the best ways that they call go greener when it comes to their computing and also help their business in the process. While many home computer users may not be quite as familiar with green computing as large firms, this term is starting to become more mainstream all around the world.

Several recent studies have found that being randomly (随机地) assigned to a roommate of another race can lead to increased tolerance but also to a greater likelihood (可能性)of conflict.
Recent reports found that lodging with a student of a different race may decrease prejudice and force students to engage in more ethnically diverse friendships.
An Ohio State University study also found that black students living with a white roommate saw higher academic success throughout their college careers. Researchers believe this may be caused by social pressure.
In a New York Times article, Sam Boakye – the only black student on his freshman year floor -said that "if you're surrounded by whites, you have something to prove."
Researchers also observed problems resulting from pairing interracial students in residences.
According to two recent studies, randomly assigned roommates of different races are more likely to experience conflicts so strained that one roommate will move out.
An Indiana University study found that interracial roommates were three times as likely as two white roommates to no longer live together by the end of the semester.
Grace Kao, a professor at Penn said she was not surprised by the findings. "This may be the first time that some of these students have interacted, and lived, with someone of a different race," she said.
At Penn, students are not asked to indicate race when applying for housing.
"One of the great things about freshman housing is that, with some exceptions, the process throws you together randomly," said Undergraduate Assembly chairman Alec Webley. "This is the definition of integration."
"I've experienced roommate conflicts between interracial students that have both broken down stereotypes(模式化形象) and strengthened stereotypes," said one Penn resident advisor (RA). The RA of two years added that while some conflicts "provided more multicultural acceptance and melding (融合)," there were also "jarring cultural resistance."
The RA said that these conflicts have also occurred among roommates of the same race.
Kao said she cautions against forming any generalizations based on any one of the studies, noting that more background characteristics of the students need to be studied and explained.

4.What can be inferred from Grace Kao’s saying about interracial lodging?
A．Schools should be cautious when making decisions about student lodging.
B．Students' racial background should be considered before lodging is assigned.
C．Experienced resident advisors should be assigned to handle the problems.
D．It is unscientific to make generalizations about it without further study.
As the railroads and the highways shaped the American West in the past centuries, a new electrical generating(发电)and transmission (输送) system for the 21st century will leave a lasting mark on the West, for better or worse. Much of the real significance of railroads and highways is not in their direct physical effect on the scenery, but in the ways that they affect the surrounding community. The same is true of big solar plants and the power lines that will be laid down to move electricity around.
The 19 th century saw land grants(政府拨地) offered to railroad companies to build the transcontinental railroads, leaving public land in between privately owned land. In much of the West, some of the railroad sections were developed while others remained undeveloped, and in both cases the landownership has presented unique challenges to land management. With the completion of the interstate highway system, many of the small towns, which sprang up as railway stops and developed well, have lost their lifeblood and died.
Big solar plants and their power lines will also have effects far beyond their direct footprint in the West. This is not an argument against building them. We need alternative energy badly, and to really take advantage of it we need to be able to move electricity around far more readily than we can now.
So trade-offs will have to be made. Some scenic spots will be sacrificed. Some species(物种) will be forced to move, or will be carefully moved to special accommodations. Deals will be struck to reduce the immediate effects.
The lasting effects of these trade-offs are another matter. The 21st century development of the American West as an ideal place for alternative energy is going to throw off a lot of power and money in the region. There are chances for that power and money to do a lot of good. But it is just as likely that they will be spent wastefully and will leave new problems behind, just like the railroads and the highways.
The money set aside in negotiated trade-offs and the institutions that control it will shape the West far beyond the immediate footprint of power plants and transmission lines. So let’s remember the effects of the railroads and the highways as we construct these new power plants in the West.

4.Which is the best title for the passage?
A．How the Railways Have Affected the West
B．How the Effects of Power Plants Can Be Reduced
C．How Solar Energy Could Reshape the West
D．How the Problems of the Highways Have Been Settled
You never see him, but they're with you every time you fly. They record where you are going, how fast you're traveling and whether everything on your airplane is functioning normally. Their ability to endure almost any disaster makes them seem like something out of a comic book. They're known as the black box.
When planes fall from the sky, as a Yemeni airliner did on its way to Comoros Islands in the India ocean on June 30, 2009, the black box is the best bet for identifying what went wrong. So when a French submarine (潜水艇) detected the box's homing signal five days later, the discovery marked a huge step toward determining the cause of a tragedy in which 152 passengers were killed.
In 1958, Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first mode for a black box, which became a requirement on all U.S. commercial flights by 1960. Early models often failed to withstand crashes, however, so in 1965 the box was completely redesigned and moved to the rear of the plane – the area least subject to impact – from its original position in the landing wells (起落架舱). The same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to aid visibility.
Modern airplanes have two black boxes: a voice recorder, which tracks pilots' conversations, and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help investigators reconstruct the aircraft's final moments. Placed in an insulated (隔绝的) case and surrounded by a quarter-inch-thick panels of stainless steel, the boxes can stand massive force and temperatures up to 2,000℉. When submerged, they're also able to emit signals from depths of 20,000 ft. Experts believe the boxes from Air France Flight 447, which crashed near Brazil on June 1,2009, are in water nearly that deep, but statistics say they're still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane's black boxes were never recovered.
1.What does the author say about the black box?
A．It is an indispensable device on an airplane.
B．The idea for its design comes from a comic book.
C．Its ability to avoid disasters is incredible.
D．It ensures the normal functioning of an airplane.
2.What does the underlined word in the 3rd paragraph mean?
A．witness B．experience C．resist D．ensure
3.Why was the black box redesigned in 1965?
A．New materials became available by that time
B．Too much space was needed for its installation.
C．The early models didn't provide the needed data.
D．The early models often got damaged in the crash.
4.What do we know about the black boxes from Air France Flight 447?
A．There is an urgent need for them to be reconstructed.
B．There is still a good chance of their being recovered.
C．They have stopped sending homing signals.
D．They were destroyed somewhere near Brazil.
