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 （內(nèi)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 （濕氣） 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.
1．The underlined word “strain” in Paragraph 1 means ________.
A．injure B．warm C．control D．burn
2．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.

3．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
4．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.
5．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

Health researchers have noticed that some groups of people are more consistently healthy than others, and wondered… Is it race? Income? Where you live? In the United States, these disagreements in health outcomes have been the focus of intense research for the past several decades.
Harvard University health policy researcher Ellen Meara says scholars have found some clues as to why some groups of people have more or less disease than others. She says one important factor in people’s health is the amount of education they have.
In her most recent paper, Meara looked at data from the United states census. These counts of people occur every 10 years. Meara and her colleagues examined data from several decades.
“We looked at life expectancy(預(yù)測壽命) at age 25,” Meara says.
“How many additional years can you expect to live if you arrive at age 25 and your education has stopped at high school, or sooner? Versus how many years, can you expect to live if you’ve reached aged 25 and you’ve gone on to at least some college…”
Meara says they found that in 1990, a 25-year-old who only had some secondary school could expect to live for a total of 75 years. In 2000, a 25-year-old with some secondary education could also expect to live to the age of 75.
In contrast, for a better educated 25-year-old, they could expect to live to the age of 80 in 1990. Someone with a similar education level in the year 2000, could expect to live to be more than 81 years, 81.6 years to be exact.
Meara says, not only do better-educated people live longer to begin with, but in the past ten years, more educated people have made gains in the length of their lives. Meanwhile, the life expectancy hasn’t changed for less educated people.
Some of these gains can be explained. Meara says researchers know that people who are more educated are more likely to quit smoking cigarettes, or not start at all, compared to people with less education.
“I think it’s a reminder not to be satisfactory,” Meara says. “Just because a population overall appears to be getting healthier, it doesn’t always mean that those advantages and successes that many people have enjoyed really extend into all parts of the population. And I think that’s something to really pay attention to regardless of whether you live in the US or elsewhere.”
Meara points out that education can often determine income---people with more education frequently make more money. This makes them aware of health care, and purchase other resources and services that can keep them healthier. But the data on income do NOT show that people who make more money are automatically healthier.
Meara says education is key. People need to be educated in order to take advantage of opportunities for better health.

1970 was World Conservation Year. The United Nations wanted everyone to know that the world is in danger. They hoped that governments would act quickly in order to conserve nature. Here is one example of the problem. At one time there were 1,300 different plants, trees and flowers in Holland but now only 866 remain. The others have been destroyed by modern man and his technology. We are changing the earth, the air and water, and everything that grows and lives. We can’t live without these things. If we continue like this, we shall destroy ourselves.
What will happen in the future? Perhaps it is more important to ask “what must we do now?” the people who will believe in the world of tomorrow are the young of today. A lot of them know that conversation is necessary. Many are helping to save our world. They plant trees, build bridges across rivers in forests, and so on. In a small town in the United States a large group of girls cleaned the banks of 11kilometers of their river. Young people may hear about conservation through a record called “no one’s going to change our world.” It was made by the Beatles, Cliff Richard, and other singers. The money from it help to conserve wild animals.

Prolonging human life has increased the size of the human population. Many people alive today would have died of childhood diseases if they had been born 100 years ago. Because more people live longer, there are more people around at any given time. In fact, it is a decrease in death rates, not an increase in birthrates, that has led to the population explosion.
Prolonging human life has also increased the dependency load. In all societies, people who are disabled or too young or too old to work are dependent on the rest of society to provide for them. In hunting and gathering cultures, old people who could not keep up might be left behind to die. In times of famine, infants might be allowed to die because they could not survive if their parents starved, where as if the parents survived they could have another child. In most contemporary(當(dāng)代的) societies, people feel a moral obligation to keep people alive whether they can work or not. We have a great many people today who live past the age at which they want to work or are able to work; we also have rules which require people to retire at a certain age. Unless these people were able to save money for their retirement, somebody else must support them. In the United States many retired people live on social security checks which are so little that they must live in near poverty. Older people have more illnesses than young or middle-aged people; unless they have wealth or private or government insurance, they must often “go on welfare” if they have a serious illness.
When older people become senile (衰老的) or too weak and ill to care for themselves, they create grave problems for their families. In the past and in some traditional cultures, they would be cared for at home until they died. Today, with most members of a household working or in school, there is often no one at home who can care for a sick or weak person. To meet this need, a great many nursing homes and convalescent (療養(yǎng)的) hospitals have been built. These are often profit making organizations, although some are sponsored by religious and other nonprofit groups. While a few of these institutions are good, most of them are simply “dumping (倒垃圾的) grounds” for the dying in which “care” is given by poorly paid, overworked, and under skilled personnel.
1. The author believes that the population explosion results from _______.
A. an increase in birthrates B. the industrial development
C. a decrease in death rates D. human beings’ cultural advances
2. It can be inferred from the passage that in hunting and gathering cultures _______.
A. it was a moral responsibility for the families to keep alive the aged people who could not work
B. the survival of infants was less important than that of their parents in times of starvation
C. old people were given the task of imparting the cultural wisdom of the tribe to new generations
D. death was celebrated as a time of rejoicing for an individual freed of the hardships of life
3. According to the passage, which of the following statements about the old people in the United States is true?
A. Many of them live on social security money which is hardly enough.
B. Minority of them remain in a state of near poverty after their retirement.
C. When they reach a certain age, compulsory retirement is necessary and beneficial.
D. With the growing inflation, they must suffer more from unbearable burdens than ever.
4. The phrase “this need” in paragraph 3 refers to ________.
A. prolonging the dying old people’s lives
B. reducing the problems caused by the retired people
C. making profits through caring for the sick or weak people
D. taking care of the sick or weak people
5. Which of the following best describes the author’s attitude toward most of the nursing homes and convalescent hospitals?
A. Sympathetic. B. Approving. C. Optimistic. D. Critical.
