The amount of time children spend in institutional care（机构式照顾）may affect how their brains develop. That’s the conclusion of a new study carried out by researchers at the University of Wisconsin, Harvard Medical School and the University of Minnesota. The study is published in Child Development in the journal’s January/ February 2010 issue.
To learn how the lack of care and material needs that institutionalized children often experience affect brain development, the researchers looked at 132 8- and 9-year-olds. Some of them were adopted into U.S. homes after spending at least a year and three quarters of their lives in institutions in Asia, Latin America, Russia and Eastern Europe, and Africa. Others were adopted by the time they were 8 months old into U.S. homes from foster care（寄养）in Asia and Latin America; most of these children had spent no time in institutional care, while some had spent a month or two in institutions prior to foster placement. On average, the internationally adopted children had been living with their families for more than 6 years. These children were compared to a group of American children raised in their birth families.
Children adopted early from foster care didn't differ from children raised in their birth families in the United States. Children adopted from institutional care performed worse than those raised in families on tests measuring visual memory and attention, learning visual information, and impulse （冲动）control. Yet these children performed at developmentally appropriate levels on tests involving sequencing and planning.
The take-home message: Children make tremendous advances in cognitive（认知的） functioning once they reach their adoptive families, but the early impact on their brains' development is difficult to change completely.
"We identified basic learning processes that are affected by early institutionalization," notes Seth Pollak, professor of psychology and pediatrics at the University of Wisconsin, who was the study's lead author. "Policies that speed the time in which children can be removed from institutionalized care so they can develop within family contexts should be implemented to decrease the likelihood of learning problems later in children's lives."
67．The passage is mainly written to___________.
A．compare two childcare systems B．criticize the institutional childcare
C．present a new research finding D．introduce the basic learning process
68．Children have their brain development affected in institutional care because__________.
A．they suffer form poor living conditions
B．they spend too much time learning
C．they don’t have freedom staying there
D．they are neither physically nor mentally satisfied
69．Compared with home-raised children, institutionalized children didn’t do as well in tasks like__________.
A．thinking in pictures and self-control
B．working in teams and self-expression
C．putting things in order and self-defense
D．adapting to the environment and self-panning.
70．It can be concluded form the passage that__________.
A．the United States is a good place for children’s all-round development
B．a perfect family is beneficial to children’s all-round development
C．children in institutional care can hardly achieve anything great
D．nothing has been done to help children in institutional care

When the TV viewer turns on his set, what sort of programs does he have to choose from? You might think there would be more programs devoted to entertainment than to anything else, but that’s not the case. In most countries, fewer than 20% of broadcasting hours are devoted to entertainment. U.S. figures are high----34.8% , and the unloving Canadians are even higher with 44%. Except Canada and Italy, all countries give more broadcasting time to education than to either information (news , documentaries and so on) or entertainment programs. Of course, few educational broadcasts take place during peak viewing times. In Japan though , more than 60%of broadcasting time is taken up with education of one kind of anther----just another example of the businesslike Japanese philosophy. In the U.K., the figure is 56.4% . the Italians have fewer educational programs than anyone else. They don’t go in for entertainment either. Only about ten percent of viewing time is devoted to dramas and serials, quiz shows, music, sports etc. You will find more news information programs on Italian TV than anything else. That’s understandable in a country experiencing social and political changes. Italians rely on TV to tell them what’s going on---and events are happening almost too fast to follow. The percentage of time the U.S. devoted to news and documentary programs is much smaller. After education, most TV time is given to entertainment. Many of these programs are shown around the world.
【小题1】Based on this passage, the greatest percentage of TV broadcasting hours to educational is in __.

【小题2】More news information programs are broadcast on Italian TV than anywhere else because the Italians ___.

A．are interested in what is happening in the world.

B．Like to follow the changes that are going on in their social life

C．Prefer to learn news information on TV rather than in newspapers

D．Expect TV to tell them the latest news about what is going on in their country

【小题3】 So far as the broadcasting hours devoted to entertainment , which of the following is true?

A．The Japanese figure is the highest in the world.

B．The U.S. figure is smaller than the U. K. figure

C．The U.K. figure is second to the Japanese figure

D．The Canadian figure is higher than that of any other country.

【小题4】In the United States, ____.

A．TV programs are shown for world audience to watch

B．Most of TV broadcasting hours are give to entertainment

C．Educational programs are shown during peak viewing times

D．TV broadcasting hours devoted to education are more than those devoted to entertainment

Try this little test. A man dressed completely in black is sitting at a bar in a country pub. He is drinking one whisky after another. After three hours, the man in black leaves the pub and walks drunkenly down a small country road. There are no lights, and there is no moon. A car without headlights approaches. The driver notices the man, however, and is able to brake in time to avoid an accident. How could the driver see the man in black? Think about this.
The reason we can get stuck with this – and other problems in life—is that we make assumptions. If we assume that the man in black is out for an evening drink, then the problem is a hard one to solve.
The dictionary describes an assumption as something we take for granted or suppose to be true. Assumptions are essential to logical thinking and decision-making, but what happens if they are false?
Sometimes false assumptions can lead to disaster. On 8 January 1989, a British Midland Airways Boeing took off from Heathrow for Belfast. The number-two (right) engine, which had caused trouble on the previous flight, had been cleared. Twenty minutes after take-off, the plane began to shake violently. The flight recorder later showed what had happened. The captain asked the co-pilot what the problem was. “It’s the f-ing right engine again!” he replied. The captain ordered no.2 engine to be shut down, and the lefthand (no.1) engine to be turned on for an emergency landing. The 737 crashed on the edge of the M1 motorway. The cause of the crash? The captain and copilot made a false assumption and shut down the wrong engine. Of the 118 passengers, 39 died and 74 suffered serious injury.
The more risky or the more expensive the decision, the more important it is to check assumptions. There is a nice way to remember the importance of assumption checking. Look at the letters in the word ASSUME, and note that taking things for granted can make an ASS（傻瓜） of U and ME.

4. The most probable reason that the driver can see the man in black is that .
A. there were bright stars in the sky when the accident happened.
B. the driver had very good eyesight.
C. the accident happened where the lights were bright.
D. the accident happened during the afternoon, in daylight.

Doctors recognize obesity as a health problem. So why is it so hard for them to talk to their patients about it?

The results of two surveys, one of primary care physicians and the other of patients, found that while most doctors want to help patients lose weight and think it is their responsibility to do so, they often don’t know what to say.

So while doctors may tell patients they are overweight, the conversation often ends there, said Christine C. Ferguson, director of the Stop Obesity Alliance. Without being told about options for diabetes, she said. “Doctors don’t feel they have good information to give. They felt they didn’t have adequate tools to address this problem.”

The lack of dialogue hurts patients, too. The patient survey, of over 1,000 adults, found that most overweight patients don’t even know at they’re too heavy. Only 39 percent of overweight people surveyed had ever been told by a health care provider that they were overweight.

Of those who were told they were obese, 90 percent were also told by their doctors to lose weight, the survey found. In fact most have tried to lose weight and may have been successful in the past — and many are still trying, the survey found. And many understand that losing even a small amount of weight can have a positive impact on their health and reduce their risk of obesity-related diseases like hypertension and diabetes.

Dr. William Bestermann Jr., medical director of Holston Medical Group, in Kingsport, Tenn., which ranks 10th in obesity among metropolitan areas in the United States, said the dialogue had to be an ongoing one and could not be dropped after just one mention of the problem. “If you’re going to be successful with helping your patients lose weight, you’re going to have to talk to them at virtually every visit about their progress, and find something to encourage them about, find progress in some aspect of their care and coach them,” he said.

He acknowledged that many doctors tend to be optimistic.

“Part of this is that there’s this common belief, and doctors are burdened by it, too, that heavy people are weak-willed and just don’t have any willpower and are self-indulgent and all that business,” he said. “If you think that way, you’re not going to spend time having a productive conversation.”

61．What is most probably the Stop Obesity Alliance, as in Paragraph 3?

A．An organization of doctors specializing in obesity.

B．An organization of patients suffering from obesity.

C．A research group that conducts special surveys about overweight people.

D．A research group dealing with doctor – patient relationship.

62．How many of the patients surveyed have been advised by their doctors to lose weight?

A．About 350. B．About 390. C．About 900. D．1,000.

63．What can be inferred about obesity patients in Paragraph 5?

A．They are not as hopeless as doctors think they are.

B．Most of them have tried hard to lose weight, but in vain.

C．Without their doctors’ constant coaching, there is little chance of their succeeding in losing weight.

D．Most of them have just given up their hope of becoming less heavy.

64．According to the passage, which factor contributes to the lack of dialogue between doctors and patients?

A．Most doctors just never think of warning their patients about their weight problem.

B．Many doctors find it difficult to persuade overweight people to lose weight.

C．Most patients are too weak – willed to do anything about their weight.

D．Many patients tend not to trust their doctors about their weight problem.

65．Which of the following is the best title of the passage?

A．Obesity in the U.S.

B．Trouble of overweight Americans

C．Talk more, help better

D．Doctors or patients – who to bear more blame?

Global surface temperatures have increased 0.6—1.2 degrees since the late 19th century. The 20th century’s 10 warmest years all happened within the last 15 years. Of these,1998 was the warmest year on record. The snow covering the Northern Hemisphere（半球）and floating ice in the Arctic Ocean decreased. Globally, sea level has risen 4—10 inches over the past century. World-wide amount of rain and snow over land has increased by about one percent. The number of major rainfall events has increased throughout much of the United States.

Increasing concentrations（集中）of greenhouse gases are likely to make climate change faster. Scientists expect that the average global surface temperature could rise 1.6—6.3 degrees by 2100，and the climate in different areas could change differently. Evaporation（蒸发）will increase as the climate warms, which will increase average global amount of rain and snow. Soil moisture（潮湿）is likely to decrease in many areas, and strong rainstorms are likely to become more frequent.Sea level is likely to rise two feet along most of the U.S coast.

Calculations of climate change for certain areas are much less able to be trusted than global ones, and it is unclear whether the climate in different areas will become more variable（变化无常的）.

64．Which of the following statements is not mentioned in the first paragraph?

A．The snow has been seen covering the Southern Hemisphere .

B．More and more major rainfall events have happened to the U.S.

C．On the whole earth, sea level has risen 4—10 inches.

D．The amount of the rain in the world has increased by about 1%.

65．According to scientists, the reason why the climate becomes warm is that________.

A．the snow covering Northern Hemisphere has decreased

B．evaporation has increased in the recent years

C．greenhouse gases concentrate increasingly

D．the floating ice in the Arctic Ocean has decreased

66．It is because______ that strong rainstorms become more frequent.

A．average global little of rain and snow increases

B．the climate becomes warm

C．soil moisture decreases

D．sea level rises two feet
