Many parents try hard to protect their kids from TV and Internet advertising. But how can
you protect a child form. a large fast-food ad painted on her school locker(小柜)? Or a toy ad on the side of his school bus?

As school budgets get smaller, a growing number of schools in the US are selling advertising space on lockers and buses and in gyms and cafeterias. It is an easy way for schools to make money. And ads may provides relief for parents exhausted by making each donations to support schools.

While parents can always turn off the television or the computer, they can’t keep advertising out of schools. This isn’t the first time the issue has come up. For example, a news program for teens has been criticized for including ads in its 12-month classroom broadcasts.

Parents groups successfully fought a plan by a company called Bus Radio to put music and ads into school buses.

But now things are different. Just last month, Los Angeles approved a plan to allow companies to advertise in the district’s schools. Officials say the plan could provide as much as $ 18 million for the school.

In St. Francis, Minn, school recently agreed to cover 10% to 15% of their lockers with ads. Edward Saxton, a teacher in the school, say, “So far, parents are accepting this as a way to bring in needed money. The money pays for programs like arts, sports, and music. Parents don’t like to see programs getting cut. Neither do I.. Besides, schools are thinking about the effects on kids all the time.”

However, Susan Linn, an educational experts, says, “Kids have already seen enough ads on TV, in magazines and on products they use daily. School is no place for advertisements at all.”

Reader, what about you? Would you rather help run yet another school fundraiser, or expose your child to ads on lockers and buses? Is keeping ads out of schools worth raising taxes, or increasing your own cash support for schools through donations?

47. Why do schools allow ads into schools?

A. To reduce parents’ burdens.

B. To solve their finanical problems.

C. To offer kids a wide choice of goods.

D. To improve their students’ living conditions.

48. Edward Saxon thinks that _____.

A. schools choose ads carefully

B. ads in schools should not be too much

C. shcools should be a place free from ads

D. in-schools do no harm to young kids.

49. What is this passage mainly about?

A. The negative efect of ads on kids.

B. Efforts to stop in-school advertising.

C. Whether ads should be allowed in schools.

D. Whether Parents should run fundraisers for schools.

50. Who are intended readers of the text?

A. Parents B. Teachers C. Educators D. Businessmen

仔细阅读:What can be done about mass unemployment? All the wise heads agree: there’re no quick or

Passage two 2016年6月英语六级卷一试题

What can be done about mass unemployment? All the wise heads agree: there’re no quick or easy answers. There’s work to be done, but workers aren’t ready to do it—they’re in the wrong places, or they have the wrong skills, Our problems are “structural, ”and will take many years to solve.

But don’t bother asking for evidence that justifies this bleak view. There isn’t any. On the contrary, all the facts suggest that high unemployment in America is the result of inadequate demand. saying that there’re no easy answers sounds wise. But it’s actually foolish: our unemployment crisis could be cured very quickly if we had the intellectual clarity and political will to act. In other words, structural unemployment is a fake problem, which mainly serves as an excuse for not pursing real solutions.

The fact is job openings have plunged in every major sector, while the number of workers forced into part-time employment in almost all industries has soared. Unemployment has surged in every major occupational category. Only three states. With a combined population not much larger than that of Brooklyn, have unemployment rates below 5%. So the evidence contradicts the claim that we’re mainly suffering from structural unemployment. Why, then, has this claim become so popular?

Part of the answer is that this is what always happens during periods of high unemployment—in part because experts and analysts believe that declaring the problem deeply rooted, with no easy answers, makes them sound serious.

I’ve been looking at what self-proclaimed experts were saying about unemployment during the Great Depression; it was almost identical to what Very Serious People are saying now. Unemployment cannot be brought down rapidly, declared one 1935 analysis, because the workforce is“unadaptable and untrained. It cannot respond to the opportunities which industry may offer. ”A few years later, a large defense buildup finally provided a fiscal stimulus adequate to the economy’s needs—and suddenly industry was eager to employ those“unadaptable and untrained”workers.

But now, as then, powerful forces are ideologically opposed to the whole idea of government action on a sufficient scale to jump-start the economy. And that, fundamentally, is why claims that we face huge structural problems have been multiplying: they offer a reason to do nothing about the mass unemployment that is crippling out economy and our society.

So what you need to know is that there’s no evidence whatsoever to back these claims. We aren’t suffering from a shortage of needed skills, We’re suffering from a lack of policy resolve. As I said, structural unemployment isn’t a real problem, it’s an excuse—a reason not to act on America’s problems at a time when action is desperately needed.

51. What does the author think is the root cause of mass unemployment in America?

A)Corporate mismanagement.

B)Insufficient demand.

C)Technological advances.

D)Workers’ slow adaptation.

52. What does the author think of the experts’ claim concerning unemployment?

A)Self-evident.

B)Thought-provoking.

C)Irrational.

D)Groundless.

53. What does the author say helped bring down unemployment during the Great Depression?

A)The booming defense industry.

B)The wise heads’ benefit package.

C)Nationwide training of workers.

D)Thorough restructuring of industries.

54. What has caused claims of huge structural problems to multiply?

A)Powerful opposition to government’s stimulus efforts.

B)Very Serious People’s attempt to cripple the economy.

C)Evidence gathered from many sectors of the industries.

D)Economists’ failure to detect the problems in time.

55. What is the author’s purpose in writing the passage?

A)To testify to the experts’ analysis of America’s problems.

B)To offer a feasible solution to the structural unemployment.

C)To show the urgent need for the government to take action.

D)To alert American workers to the urgency for adaptation.

"Freshman fifteen" is a term which means fifteen pounds, or about seven kilograms— the wei
ght students might expect to gain in their first year of college. People used to talk about the "freshman ten." Before that, it was the "freshman five." Are freshman more inflated, or just the expression? The fact is, many young men and women do put on extra weight when they start college. Some schools that have done research on the issue including Cornell University in Ithaca, New York, have found that freshmen gain an average of four pounds during their first twelve weeks, the equivalent of two kilograms. If weight gain continues at this rate, how long before they put on fifteen pounds? The answer is forty-five weeks, or almost a year. The next question is, why do so many freshmen gain weight? The answers listed by experts are not so surprising. One is poor diet: College students often eat foods high in fat and sugar and starch with no parents around to say no to junk food. Students may also miss meals. They could be in class or studying or just ... busy. In any case, those who miss meals are more likely to overeat when they do have food. Also, freshmen often use food to put their mind at ease. They have college pressures to deal with. Not only that, many are living away from home for the first time. Another reason college students gain weight is that they often do not get enough exercise. Finally, there is something else that can add up to the "freshman five" or ten or fifteen, alcohol. Alcohol is high in calories and this is especially true of beer. And, no, freshmen are not supposed to be drinking, not unless they are twenty-one, the legal drinking age in America. For many college students, the extra weight they put on in their freshman year can be as hard to escape as term papers and final exams.

Paragraph 1 is centered on______.

A.why freshmen put on weight in college

B.why freshmen worry about their weight

C.how the "freshman fifteen" gets its name

D.how the "freshman fifteen" amazes freshmen

第10题
The other day I heard an American say to a Chinese student of English "You speak very good
English." But the student answered, "No, no. My English is very poor." the foreigner was quite surprised at the answer. Thinking he had not made himself understood or the student had not heard him clearly, he said, "Yes indeed, you speak English very well." But the Chinese student still kept saying "No. "In the end the foreigner gave up and was at a loss what to say. What's wrong with the student's answer? It is because he did not accept a compliment<赞美的话>as the English people do. He should have said "Thank you" instead of "no". He actually understood what the American had said. But he thought he should be modest. If he said "Thank you", that would mean he was too proud. According to the western culture, if someone says the dishes you have cooked are very delicious, you should say "Thank you". If someone says to a woman "You look so beautiful with the new clothes on", she should be very happy and answer "Thank you". In our country we think being modest is a virtue and showing off a bad thing. But in the west, if you are modest and say" No, I'm afraid I can't do it well", then the others will take it for granted that you really cannot do it. If you often say "no", you will certainly be looked down upon by others. If asking for a job, one says something like "Let me have a try on the job" instead of "Yes, I can certainly do it," he or she will never expect to get it. So in the west one should always be confident. Without self-confidence, he cannot go anywhere. Confidence is of great importance to one in a country where competition is quite keen.

Why was the American surprised at the Chinese student's answer?

A.Because he wondered whether the student could really speak good English.

B.Because he could hardly hear what the student had said.

C.Because he wouldn't like others to say "No".

D.Because the way to accept a compliment in China is not the same as that in the western countries.
