People who enjoy a dream-filled sleep are better at recalling information and making links between facts when waking. But recharging with a shallow (小睡) offers no such mental improvement, the research suggests. The results of the study added to the growing body of evidence that Rapid Eye Movement (REM) sleep is very important to the brain’s ability to form strong memories.

An average night's rest includes four or five spells of REM sleep, but these bursts tend to be lengthier towards the end of the night. This means adults getting less than the recommended seven to eight hours a night -- and therefore inadequate REM sleep -- may be damaging their mind's ability to memorize: Although REM sleep is not classified as a type of deep sleep, it is only reached after the brain has passed through deep sleep stages.

In the recent study, participants were shown groups of three words and asked to find another word that can be associated with all three words. They were tested once in the morning and then given the same task again in the afternoon. In between, some were allowed a nap with REM sleep, some a nap without REM sleep, while the others had a quiet rest period. The quiet rest and non-REM sleep groups didn't improve, but the REM sleep group improved on their morning performance by an average of almost 40 per cent. Dr Sara Mednick, a sleep researcher at the University of California who led the study, believes the formation of connections between previously unassociated information in the brain occurs during REM sleep.

It is believed that sleep acts as a sort of mental filing system, enabling the brain to sort relevant information from useless information. This process may take place as memories are removed hem one art of the brain to others.

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.
