Eating foods high in trans-fats(fats present in artificial form in industrially-produced cakes and fast food...) and saturated (饱和的) fats increases the risk of depression, according to a Spanish study, confirming previous studies that linked “junk food” with the disease. Researchers also showed that some products, such as olive oil, can fight against the risk of mental illness.
Authors of the wide-reaching study, from the universities of Navarra and Las Palmas, followed and analyzed the diet and lifestyle of over l2,000 volunteers over six years. When the study began, none of the participants had been diagnosed with depression; by the end, 657 of them were new sufferers.
“Participants with an increased consumption of trans-fats presented up to a 48 percent increase in the risk of depression when they were compared to participants who did not consume these fats,” the head study author said. “The more trans-fats were consumed, the greater harmful effect they produced in the volunteers.”
The research team found, at the same time, that after assessing the effect of polyunsaturated fats made up of larger amounts of fish and vegetable oils and olive oil, these products are associated with a lower risk of suffering depression.
The report, published in the online journal PLOS ONE, noted the research was performed on a European population that enjoys a relatively low intake of trans-fats—making up only 0.4 percent of the total energy taken in by the volunteers. “Despite this, we observed an increase in the risk of suffering depression of nearly 50 percent,” said researcher Miguel Martinez. “On this basis we think it of great importance to take this effect into account in countries like the United States, where the percentage of energy derived from these fats is around 2.5 percent.”
The report pointed out that the current number of depression sufferers in the world is around l50 million people, and has increased in recent years. This rise is attributable, according to the authors, “to great changes in the sources of fats consumed in Western diets, where we have replaced certain types of beneficial fats in nuts, vegetable oils and fish with the saturated and trans-fats found in meats, butter and other products such as mass-produced cakes and fast food.”What's the best title of the text?

Mark was walking home from school one day when he saw the boy in front of him fall over and drop all of the book
s he was carrying, along with two sweaters, a basketball and a walkman（随身听）. Mark stopped and helped the boy pick up these things. Since they were going the same way, he helped to carry some of his things. As they walked, Mark knew that the boy’s name was Bill, that he loved computer games, basketball and history, and that he was having lots of troubles with his other subjects and that he had just broken up with his girlfriend.
They arrived at Bill’s home first and Mark was invited in for a Coke and to watch some television. The afternoon passed happily with a few laughs and some small talk, and then Mark went home. They often saw each other at school, had lunch together once or twice, and then they both finished middle school. They ended up in the same high school where they sometimes saw and talked with each other over the years. At last just three weeks before they finished high school, Bill asked Mark if they could talk.
Bill asked Mark if he still remembered the day years ago when they had first met. “Did you ever think why I was carrying so many things home that day?” asked Bill. “You see, I cleaned out my locker(锁柜) because I didn’t want to leave anything for anyone else. I had put away some of my mother’s sleeping pills and I was going home to kill myself. But after we spent some time together talking and laughing, I began to 
understand that if I killed myself, I would have missed that time and so many others that might follow. So you see, Mark, when you picked up those books that day, you did a lot more. You saved my life.”When Mark met him the first time, Bill was going _______.

A great French writer said that we should help everyone as much as possible because we often need help ourselves. The small even can help the great. To this effect, he tells a simple story.
An ant was drinking at a small river and fell in. She tried hard to reach the side, but made no progre
ss at all. The poor ant, almost tired out, was still bravely doing her best when a bird saw her. Moved with pity, the bird threw her a blade (叶片) of grass, which supported her like a boat, and thus she
reached the bank again. While she was resting and drying herself in the grass she heard a man coming near. He was walking along barefooted and carrying a gun in his hand. As he saw the bird he wished to kill her, and he would certainly have done so, but the ant bit him in the foot just before he raised his gun to 
fire. He stopped to see what had bit him, and the bird immediately flew away. It w
as an animal much weaker and smaller than herself that had saved her life. According to the French writer, we often need help from others, therefore we should________.
| A．not help others | B．help those who may be helpful to us |
| C．get as much help as possible | D．help others as much as we can |

People who are outdoors in cold weather should avoid actions like suddenly lifting a heavy basket full of snow. Even walking through heavy, wet snow can strain a person’s heart.
Many people aren’t conditioned to the physical stress of outdoor activities and don’t know the dangers of being outdoors in cold weather. Those who like winter sports can suffer accidental hypothermia if they don’t make certain preparations.
Hypothermia means the body temperature has fallen below normal. It occurs when your body can’t produce enough energy to keep the internal (内部的) body temperature warm enough. It can kill you. Heart failure causes most deaths in hypothermia.
Children, the elderly and those with heart disease are at special risk. As people age, their ability to keep a normal internal body temperature often decreases. Elderly people can suffer hypothermia without knowing they’re in danger because they can’t notice the cold conditions as quickly as the young.
Besides cold temperatures, high winds, snow and rain can also steal body heat. Wind is especially dangerous because it removes the layer of heated air from around your body. At 30 degrees Fahrenheit in a 20-mile-per-hour wind, the cooling effect is equal to calm air at four degrees. Similarly dampness (湿气) causes the body to lose heat faster than it would at the same temperature in drier conditions.
To keep warm, wear more clothes. This traps air between layers. Also, wear a hat or head scarf. Much of your body’s heat can be lost through your head. Keep your hands and feet warm, too, as they tend to lose heat rapidly.
Don’t drink alcohol before going outdoors or when outside. Alcohol makes you feel warm at first because blood vessels in the skin expand. But heat is then drawn away from the body’s important organs.The underlined word “strain” in Paragraph 1 means ________.
| A．injure | B．warm | C．control | D．burn |
What is implied in the passage about hypothermia?
| A．It means the body temperature falls rapidly. | B．Most heart attacks are caused by it. |
| C．It is not as scary as people think. | D．It can threaten a person’s life. |
Based on the passage, one of the reasons why the elderly are at special risk of suffering from hypothermia is that _______.
| A．they like exercising outside in cold mornings |
| B．they can’t notice cold conditions if they are not told |
| C．their body temperature is generally lower than young people’s |
| D．their ability to keep a normal internal body temperature is not so good |
What is Paragraph 5 mainly about?
| A．What causes the body to lose heat faster. | B．The advantages of drier conditions. |
| C．What else can steal body heat. | D．Dangers of high winds. |
Which of the following is NOT a result of drinking alcohol before going outdoors?
| A．Feeling warm at first | B．The body’s heat is taken away |
| C．Blood vessels in the skin expand | D．The risk of hypothermia is reduced |
The United Nations says forty million people or so around the world went hungry in 2008, mainly because of higher food prices. Early estimates from the UN Food and Agriculture Organization (FAO) show that 963 million people did not get enough to eat.
World food prices have dropped since early 2008. Prices of major crops have decreased by more than half from their height earlier last year. But they remain high compared to earlier years.
But FAO official Hafez Ghana says lower prices have failed to end the food crisis（危机）in many poor countries. "For millions in developing countries," he says, "getting enough food every day to live an active and healthy life is a distant dream.”
The FAO says food shortage is a threat to people's health. Today, two-thirds of the world's undernourished people live in just a few countries. These are India, the Democratic Republic of Congo, Bangladesh, Indonesia, Pakistan, Ethiopia and so on.
A report on food insecurity warns that the current economic crisis could send even more people into hunger and poverty.
In sub-Saharan Africa, the percentage of the people who continually go hungry fell from 34% in 1997 to 30% in 2008. But the FAO says Ghana is the only country that has reached two sets of hunger reduction targets. These were set by the 1996 World Food Summit and the Millennium Development Goals. The main reason is the growth in agricultural production in Ghana.
The FAO says some countries in Southeast Asia like Thailand and Vietnam have made progress in hunger reduction goals. But South Asia and Central Asia haven't, and North Korea is still in hot water. What FAO official Hafez Ghana says implies _________.
| A．it's easy but takes long to provide people with enough food |
| B．enough food can make people more active and healthier |
| C．there is difficulty solving the food shortage in a short time |
| D．people in developing countries will never get enough food |
Ghana has reached the targets of hunger reduction mainly because of ________.
| A．the still high food prices | B．the donation of developed countries |
| C．the two targets of hunger reduction | D．the growth in agricultural production |
The underlined word “undernourished” in Para. 4 probably means _________.
| A．hungry and unhappy | B．unhealthy for lack of food |
| C．not fat because of poverty | D．undeveloped and poor |
Which country has not made progress in hunger reduction?
| A．North Korea | B．Thailand | C．Vietnam | D．Ghana |
What is the best title of this passage?
| A．The food production of the world | B．The hunger reduction target of the FAO |
| C．The food shortage around the world | D．The solution to the global food shortage |
