According to the United States government, people are classified as homeless if they have no place to stay and no expectation of finding a place for the next thirty days．Although technically accurate, that is an impersonal assessment of an enormous and very human problem．
The homeless population represents all of us Americans．It includes men and women, the elderly, children, and infants．Its members are from all ethnic groups．What they have in common is poverty．
Currently in the U．S．, thirty-nine million people live in poverty．When money is really tight, paying the rent or buying food often becomes a choice．Government assistance in the form of food stamps does help but, as one homeless man explains, you can’t pay the rent with food stamps．
With no money for rent, the streets and homeless shelters become the alternative．
Although men constitute the largest group within the homeless population, homeless women with children are rapidly joining them．In fact, one quarter of the homeless people in the U．S．are teenagers and young children．
People may become homeless for numerous reasons．However, there are certain factors that many of these individuals have in common．They include a lack of adequate education and job skills．A majority of the teenagers and adults have not completed high school．
The abuse of alcohol and drugs is also a common factor．One third of the adult homeless population abuses alcohol．While one quarter of the same group uses drugs．
Some members of this population suffer mental health problems．Within the past several years many institutions for the mentally ill have been closed and their patients sent “home”．Unfortunately, a number of those people have no home to go to and they are unable to adequately look after themselves．
Job loss in today’s economy has also become a real factor in the loss of people’s homes．The breakup of families through abandonment and divorce are also contributing factors, particularly when there are children involved．The parent who is left to care for the kids with inadequate income may be forced to depend on the homeless shelters to put a roof over their heads．The writer thinks that the U．S．government’s definition for the homeless reveals ________．
| A．an insincere attitude toward the homeless |
| B．an unbearable attitude toward the homeless |
| C．an uncivilized attitude toward the homeless |
| D．an unsympathetic attitude toward the homeless |
The U．S．government helps the homeless by ___________．
| A．giving them homeless allowance |
| B．giving them food stamps |
| C．finding jobs for them |
| D．finding residence for them |
People become homeless for all the following reasons E XCEPT __________．
| A．the lack of adequate education |
| B．the abuse of alcohol and drugs |
| C．the closure of institutions for the mentally ill |
| D．the poor performance of economy |
The breakup of families is likely to lead to homelessness because a parent with kids may_____．
| A．lose his or her job in today’s economy |
| B．be unable to look after the kids |

| D．find residence at a homeless shelter |
The scene in the Hollywood movie The Day After Tomorrow, when global warming could soon turn the global climate into a new ice age, may never occur, according to a new research.
The next ice age could be 15,000 years away, say European scientists who last month announced a continuous record of 740,000 years of climate data obtained from the Antarctic ice.
Scientists from 10 nations have now almost completely drilled through a 3,000-meter depth of ice high in the Antarctic mainland. They figure out that the area, where summer temperatures can fall to – 40℃, has at least 900,000 years of snowfalls, kept as neatly as the growth rings of a tree. And the ice and air caught in each layer(层) have begun to answer questions about the climates in the past..
The results show that there have been eight ice ages in the past 740, 000 years and eight warmer periods. And by comparing the pattern of global conditions today with those of the past, the researchers reported in Nature that the present warm period could last another 15, 000 years.
Research suggests that there is a very close connection between greenhouse gas levels and global average temperatures. It also shows that carbon dioxide (二氧化碳) levels are the highest for at least 440,000 years.
"If people say to you: ‘the greenhouse effect is a good thing because we would go into an ice age otherwise,’ our data say no, a new ice age is not hanging over our heads,” said Eric Wolff from the British Antarctic Survey. "Now we have eight examples of how the climate goes in and out of ice ages… and you can learn what the rules are that go into the climate models that tell us about the future."
Scientists found that whenever temperatures rose in the frozen record, so did carbon dioxide level. "In 440,000 years we have never seen greenhouse gas get as thick as it is today," said Dr Wolff.In drilling through the ice in Antarctica, scientists have found that______.
| A．the lowest temperature there is – 40℃ |
| B．the depth of ice is 3,000 meters |
| C．the ice has existed for 15,000 years |
| D．snowfalls are kept in certain patterns |
The information of the global climate conditions in the past can be obtained through______.
| A．separating carbon dioxide from the air |
| B．examining the growth rings of trees |
| C．comparing temperatures in different areas |
| D．studying the ice and air caught in each layer |
We can infer from Eric Wolff's words that_______.
| A．there is something wrong with the data |
| B．greenhouse effect is always a bad thing |
| C．a new ice age will not come in the near future |
| D．greenhouse gas will get thick in the future |
What would be the best title for the passage?
| A．Research over the Antarctic area. |
| B．Warm period to last about 15, 000 years. |
| C．Report on the eight ice ages in the past. |
| D．Hollywood movies and the global climate. |
Money is the root of all evil and new study claims there may be some truth behind the saying．Scientists at the University of California, Berkeley, US，announced on February 27 that rich people are more likely to do unethical (不道德的) things, such as lie or cheat, than poorer people．
The scientists did a series of eight experiments. They published their findings online in the Proceedings of the National Academy of Sciences (PNAS,《美国国家科学院院刊》)．
They carried out the first two experiments from the sidewalk near Berkeley. They noted that drivers of newer and more expensive cars were more likely to cut in on other cars and pedestrians at crosswalks. Nearly 45 percent of people driving expensive cars ignored a pedestrian compared with only 30 percent of people driving more modest cars．
In another experiment, a group of college students was asked if they would do unethical things in various everyday situations. Examples included taking printer paper from work and not telling a salesperson when he or she gave back more change. Students from higher-class families were more likely to act dishonestly.
According to the scientists, rich people often think money can get them out of trouble. This makes them less afraid to take risks. It also means they care less about other people’s feelings.
Finally，it simply makes them greedier．“Higher wealth status seems to make you want even more，and that increased want leads you to bend the rules or break the rules to serve your self-interest,” said Paul Piff, leading scientist of the study.
Piff pointed out that the findings don’t mean that all rich people are untrustworthy or that all poor people are honest. He said the experiments were to show how people living in different social situations express their instincts and values in different ways.By saying “money is the root of all evil”，the author wants to ____________．
| A．draw readers’ attention to the research |
| B．1ink wealth with bad behavior |
| C．show how the saying proves the findings |
| D．defend rich people who do unethical things |
What makes rich people unethical according to the scientists?
a．they become more selfish b．they have more desires
c．they believe money talks d．they welcome risks
| A．a、b | B．a、b、d |
| C．b、c | D．a、b、c |
Why did the scientists do the experiments?
| A．To show how social status affects people's ethics． |
| B．To show people’s instincts and values in different ways. |
| C．To test whether the saying “money is the root of all evil” is true． |
| D．To show the difference between higher-class people and lower-class people． |
What does the article really want to show us?
| A．Money is the root of all evil． |
| B．The rich are more likely to act badly． |
| C．The saying is unreasonable． |
| D．All rich people are untrustworthy． |
Thousands of people began pouring into Pennsylvania from other states. They wanted to buy lottery tickets. The tickets cost only $ 0.9 each. But that small spending could bring them a reward of $ 90 million .That was the second largest lottery jackpot （积累奖金）in history.
More than 87 million tickets were bought for the Pennsylvania lottery drawing. Those who bought tickets had to choose seven numbers from 1 to 80．The chance of winning was one in 9.6 million, but that little chance certainly didn’t affect ticket sales. In the last few days before the drawing, tickets were sold at the unbelievable rate of 500 per second.
Experts say many people buy lottery tickets because they just want to have a piece of the action. Others say the lottery is a stock market for poor people. It allows them to dream about wealth they’ll probably never have.
But many people believe lotteries are no better than legalized gambling. Some critics note that most people who play are poor and may not be able to afford the tickets. There are also many addicts who take the game seriously. They may pour their life savings into lottery tickets. Some clubs have been formed to help them kick the habit.
Politicians like lotteries because they provide money that would otherwise have to come from new taxes. The profits from lotteries are usually used to pay for education or programs for senior citizens. But critics say this arrangement just allows states to legalize vice(恶习), under the name of social progress. Whether you regard stock lotteries right or not, you cannot refuse to accept their extreme popularity with many Americans.The main idea of the passage is that __________.
| A．lotteries are of great benefit to everyone who buys them |
| B．playing a lottery is just like investing in the stock market |
| C．many people buy lottery tickets , but lotteries cause disagreement |
| D．lotteries are nothing but legalized vice |
Which of the following is TRUE according to the passage?
| A．Politicians like lotteries because they don’t have to pay extra taxes. |
| B．The popularity of lotteries in America actually is social progress. |
| C．Some critics don’t like lotteries because many poor people waste money on them. |
| D．People love the lottery because it is a stock market. |
In just one hour in the last few days, the Pennsylvania lottery sold tickets totaling_______.
| A．$ 1.62 million | B．$ 1.82 million |
| C．$ 9.6 million | D．$ 87 million |
People who are addicted to playing lotteries should __________.
| A．join a support group | B．kick the habit |

The arts, especially music, should be part of every school's lessons at every grade level. Students would be much smarter if they had some musical experience. They could improve their classroom skills, like paying attention and following directions. People develop all these skills when they learn music. Making music also lets children use their imagination. It provides students with a chance to try out their own ideas.
Music not only makes children better students, but also gives them something positive to do. In a music program, children can be part of a band instead of joining a gang(团伙). Parents can enjoy listening to their children's music instead of seeing them glued to a computer or TV screen. In a school band, students get to be part of a team. They can get along well with old friends and make new friends through music.
Music builds self-confidence, too. It gives children a sense of achievement and success. Making music is something for them to be proud of, and it lets kids practice performing in front of an audience. Music gives children an opportunity for self-expression, and that helps develop their self-confidence.
Once again, music is important because it can make children better students, give them something positive to do, and build their character. That is why music should be offered in every single grade in every school.According to the passage, music could make students smarter by __________.
| A．improving their classroom skills and paying attention |
| B．improving their classroom skills and imagination |
| C．improving their attention, direction and imagination |
| D．learning music, making music and trying out their own ideas |
What does the underlined phrase "glued to" in the second paragraph mean?
| A．unwilling to turn on | B．always looking |
| C．unwilling to leave | D．always playing |
The third paragraph mainly tells us that music could _______________.
| A．give children self-expression and self-confidence |
| B．bring to children achievement and success |
| C．give children something to be proud of |
| D．develop children's self-confidence |
What's the best title of this passage？
| A．Music is a must as a course at school |
| B．Music builds children's self-confidence |
| C．Music makes students much smarter |
