It is difficult for doctors to help a person with a damaged brain. Without enough blood, the brain lives for only three to five minutes. More often the doctors can’t fix the damage.Sometimes they are afraid to try something to help because it is dangerous to work on the brain. The doctors might make the person worse if he operates on the brain.
Dr.Robert White, a famous professor and doctor, thinks he knows a way to help. He thinks doctors should make the brain very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctor a longer time to do something for the brain.
Dr.White tried his idea on 13 monkeys. First he taught them to do different jobs, then he operated on them. He made the monkeys’ blood go through a machine. The machine cooled the blood. Then the machine sent the blood back to the monkeys’ brains. When the brain’s temperature was 10 ℃, Dr.White stopped the blood to the brain. After 30 minutes he turned the blood back on. He warmed the blood again. After their operations the monkeys were like they had been before. They were healthy and busy. Each one could still do the jobs the doctor had taught them.

To conduct the research, Boniel-Nissim and Barak randomly selected Israeli high school students who displayed a certain degree of stress. The teenagers were then divided into six groups. Two groups were asked to post blogs twice a week about their social difficulties, but only one of them was asked to open the blogs for comments. The next set of groups were also asked to blog twice a week to post about whatever was going on in their mind, again with one group allowing comments. The two control groups were asked to keep an old-fashioned private diary.
The researchers then collected the blog posts and diaries to discuss the adolescents’ emotional and social position. From the research, they saw that the greatest improvement in mood was with the bloggers who wrote about their personal troubles and allowed people to interact with their posts. The research also noted that the comments were mostly positive and constructive. Boniel-Nissim and Barak said that the commentators’ interactions helped the bloggers while they were distressed. The conclusive research noted that expressing yourself on the Internet not only let others know what was personally going on with you, but also helped you figure out some things about yourself too.

Why was his idea successful? Probably the most important reason was that his timing was right. In the 1950s, most married women stayed home to keep house and take care of their children. In the 1960s, many women returned to the workplace. This meant that they had less time or energy to prepare meals, so they spent more on “ TV dinners ” and fast-food restaurants. Single parents also have little time to spend in the kitchen. People living alone also depend on this type of food, since cooking for one is often more trouble than it is worth.
Fast-food is not part of the diet of all Americans. Another trend of the 1960s, sometimes called the back-to-nature movement influenced many people to avoid food that was packaged (包装) or processed(处理). This preference for natural food continued to this day.
From the success of Raymond Kroc’s fast-food business, we can say that social economic trends influence where and what we eat.

D.cooking for one person cost more money |
A.many married women began to work in the 1960s |
B.natural foods are still popular today |
C.fast food is not part of the diet of all Americans |
D.divorce (离婚) causes people to change their eating habits |
A.people living alone tend to depend on fast food |
B.single parents have little time to spend in the kitchen |
C.many women returned to the workplace in the 1960s |
D.Kroc chose the “Mc Donald” brothers as his partners |
A.Raymond Kroc is the most successful fast-food business owner in the world |
B.social and economic changes affect eating habits |
C.fast-food is easy to prepare and serve quickly |
D.Americans eat either fast food or natural food |
It had long been well known among farmers that people who worked with cows seldom caught smallpox; instead, they often caught a similar but much milder disease called cowpox (牛痘) . A British doctor called Jenner was extremely interested in this, and so he studied cowpox. He believed that, by vaccinating (给接种疫苗) people with the disease, he could protect them against the much worse disease smallpox. In 1796, he vaccinated a boy with cowpox and, two months later, with smallpox. The boy did not get smallpox. In the next two years, Jenner vaccinated several children in the same way, and none of them got the disease.
News of the success of Jenner’s work soon spread. Vaccination soon became a common method to protect people against other diseases caused by virus, such as rabies (狂犬病), and vaccines were sent across the world to the United States and India.
It took nearly two centuries to achieve Jenner’s dream of getting free of smallpox from the whole world. In 1967, the world Health Organization (WHO) started a great vaccination program, and the last known case of smallpox was recorded in Somalia in 1977. The story of vaccinations does not end there, however. There are many other diseases that kill more and more people every year. Besides, many new diseases are being discovered. The challenge for medical researchers will, therefore, probably continue for several more centuries
小题1:Smallpox was so serious that _________________ by the end of l8th century
A.its death rate was up to ten percent |
B.those who caught it were certain to die |
C.one in ten people in the world died of smallpox |
D.one in ten deaths in the world was caused by smallpox |
A.make smallpox much milder |
B.stop people from getting smallpox |
C.protect people against any disease |
D.prevent people’s scars after smallpox |
A.The first experiment with cowpox was made by a British doctor. |
B.After 1977 smallpox disappeared around the world according to WHO. |
C.Vaccination had existed among ordinary farmers before being discovered. |
D.Vaccination can be used to protect people in the world against not only smallpox. |
A.vaccinations bring many new problems |
B.vaccinations end the spread of diseases |
C.there is a long way to go to fight against diseases |
D.there is a long way to go to discover new diseases |
These days, people are concerned about the growing number of kids who are overweight. The number of overweight kids has increased a lot over the last 30 years. Today, more than 15% of the kids aged 6 to 19 are overweight.
In a recent study in the USA, 1,168 boys and girls were asked about the problem. More than half of them said too many girls were overweight.
What does “Overweight” Mean?
Most people who are overweight have too much body fat. The person who is overweight weighs more than is healthy. Being overweight can lead to health problems, like heart disease. Overweight kids also may feel sad about the way they look. Sometimes they get laughed at by other kids and it is harder for overweight kids to make friends.
Why Are Some Kids Overweight?
When asked why some kids were overweight, many kids said it was because overweight kids didn’t exercise enough or eat right. Others said that kids were overweight because fast food restaurants serve the wrong foods or it’s a problem of genes.
How Are the Kids Trying to Lose Weight?
Plenty of kids said they have tried to lose weight and they have been trying to do the following:
● go on a diet – 17%
● eat healthy and exercise – 64%
● eat out less – 4%
● take medicine – 5%
It’s great that kids are thinking about weight problems and are trying to solve them. It’s like putting together a difficult puzzle. Understanding that there’s a problem is one piece. Understanding what causes kids to be overweight is another. And knowing that eating healthy and exercising are the best ways to fix the problem is a very important piece.
小题1:How do overweight kids feel about the way they look?
___________________________________________________________________
小题2:Some kids have tried to lose weight. What have 64% of them been trying to do?

小题3:What is the passage mainly about?

Those who choose to be creators look at life quite differently. They know there are individuals who might like to control their lives, but they don’t let this get in the way. They know they have their weaknesses, yet they don’t blame themselves when they fail. Whatever happens, they have choice in the matter. They believe their dance with each sacred(神圣的)moment of life is a gift and that storms are a natural part of life which can bring the rain needed for emotional and spiritual growth.
Victims and creators live in the same physical world and deal with many of the same physical realities, yet their experience of life is worlds apart. Victims relish (沉溺)in anger, guilt, and other emotions that cause others---and even themselves---to feel like victims, too. Creators consciously choose love, inspiration, and other qualities which inspire not only themselves, but all around them. Both victims and creators always have choice to determine the direction of their lives.
In reality, all of us play the victim or the creator at various points in our lives. One person, on losing a job or a special relationship, may feel as if it is the end of the world and sink into terrible suffering for months, years, or even a lifetime. Another with the same experience may choose to first experience the grief, then accept the loss and soon move on to be a powerful creative force in his life.
In every moment and every circumstance, you can choose to have fuller, richer life by setting a clear intention to transform the victim within, and by inviting into your life the powerful creator that you are.
小题1:What does the word “they” in Paragraph 1 probably refer to?
A.People and things around you. | B.Opportunities and problems. |
C.Creators and their choices. | D.Victims and their sufferings. |
A.seem willing to experience failures in life |
B.possess the ability to predict future life |
C.handle ups and downs of life wisely |
D.have potential to create something new |
A.Creators and victims face quite different things in life. |
B.Creators and victims are masters of their lives. |
C.Victims can influence more people than creators. |
D.Compared with victims, creators are more emotional. |
A.strong attachment to sufferings in life pulls people into victims. |
B.people need family support to deal with challengers in life. |
C.it takes creators quite a long time to get rid of their pains. |
D.one’s experiences determine his attitude toward life. |
A.To define victims and creators. |
B.To evaluate victims against creators. |
C.To explain the relationship between victims and creators. |
D.To suggest the transformation from victims to creators. |
