Even facts “forgotten” by people during a busy day may be retrieved if this is followed by a good night’s sleep.

Researchers from the University of Chicago asked volunteers to remember simple words．Many found their memories letting them down towards the end of the day, but the following morning, those who had slept well could recall much more.

Researchers, writing in the journal Nature, said the brain could “rescue” lost memories during the night.

When the brain is first asked to remember something that memory is laid down in an “unstable” state, meaning that it is possible that it could be lost．At some point, the brain consolidates those it deems important into a “stable”, more permanent state．However, the Chicago researchers suggested that it was possible for a “stable” memory to be made “unstable” again．This would mean that memories could be modified then filed away again in the face of new experiences.

The 12 volunteers tested in the experiment were played words created through a speech synthesizer which were purposely difficult to understand．Initially, the written version of the word  from the audio version only．Tests revealed that the ability to recall the right word tended to tail off as the day ended.

However, when the volunteers were retested after a good night’s sleep, they were able to recall some words that they had “ forgotten” the previous evening.

Dr Daniel, one of the study authors, said: “Sleep consolidates memories, protecting them against subsequent interference or decay．Sleep also appears to “recover” or restore memories.” He said: “If performance is reduced by decay, sleep might actively recover what has been lost.”

Dr Karim Nader, from the Department of Psychology in McGill University in Montreal, said: “Memory research is undergoing a transformation---no longer is memory thought to be a hard-writing of the brain, instead it seems to be a process of storage and restorage.”

Sleep helps some memories “mature” and also prunes out unimportant memories.

72．What does the first paragraph implies?

       A．A busy day makes people forget things easily.

       B．People need a good night’s sleep after a busy day.

       C．A good night’s sleep helps memories.

       D．A good night’s sleep helps people forget a busy day.

73．The words the 12 volunteers played in the experiment were not ____

       A．created through a speech synthesizer

       B．hard to understand

       C．available at the beginning

       D．designed to test people’s ability of understanding

74．According to the passage, memory_____

       A．is a hard-writing of the brain

       B．is not a process of storage

       C．is not a process of restorage

       D．will be mature with the help of sleep

75．Which of the following is NOT true?

       A．When people first remember something, the memory is in an “unstable state”.

       B．The brain will change those important unstable memories into stable.

       C．Once the memory become stable, it will never become unstable again.

       D．Sleep can protect memories from being harmed.

Obesity is becoming one of the biggest threats to children’s health, a recent nationwide investigation has warned, pointing out that students’ physical indicators are declining because of a lack of enough exercise.

The past five years have witnessed fast growth in the number of fat children—in some big cities, the number has even doubled, the survey showed.

In Beijing, for example, latest figures from the local education authorities show that the height, weight and chest measurement of young students keep expanding, while physical indices, such as lung capacity, speed and strength, are going down.

The blood pressure of half the secondary school students is above normal; and the number of obese students has increased by 50 percent compared with five years age.

In the urban areas of Beijing and five other economically more developed regions, the average obesity rate of male students in primary schools has reached 12.9 percent.

Nationwide, the obesity rate of children is 8.1 percent and 3.1 percent in urban and rural areas.

“China has entered the era of obesity,” Beijing-based Workers’ Daily quoted Ji Chengye of the Child and Adolescent Health Section of the China Preventive Medicine Association as saying．“Childhood is the first age group affected by obesity, to which society has not paid enough attention,” Ji said．“Obesity in childhood will influence health for life,” the expert added.

The increase in indoor activities such as watching television, surfing the Internet, playing computer games or doing homework, is one of the main reasons for children’s obesity, according to Ji, because it means lack of exercise and little chance for burning calories．Another reason is consumption of excessive junk food．“In the past, children used to drink water．Now they prefer sweet beverages; and some have totally given up water,” Ji said．He also blamed intensive promotions of sweets and junk food, which make it hard for children to resist the temptation.

Also, because of pressure of competition to enter good higher schools, teachers sacrifice students’ physical exercise time for classes.

For instance, about 60 percent of school masters in Beijing admitted that the one hour of outdoor physical exercises per day is not always followed.

“Problems of obesity will not only influence children’s physical and psychological development but also become a “time bomb for the country’s future economic development and public health system,” said Chen Chunming, head of International Life Sciences Institute Focal Point in China.

61．How many reasons are mentioned in the passages that cause child obesity.

A．two                      B． three                   C．four                    D．five

62．Problems of obesity will not ________

A．influence children’s physical and psychological development

B．affect the country’s future economic development

C．have some effect on the country’s public health system

D．harm human history

63．What does the underlined word “obesity” mean?

A．being strong     

B．being too small

C．being too fat

D．being too tall

64．What’s the main idea of the passage?

       A．child obesity has become a big problem

       B．the problem of child obesity is especially serious in Beijing

       C．China has entered the era of obesity

       D．lacking enough exercise is the main reason for children’s obesity

Americans are pound of their variety and individuality, yet they love and respect few things more than a uniform, whether it is the uniform of an elevator operator or the uniform of a five-star general．Why are uniforms so popular in the United States?

Among the arguments for uniforms, one of the first is that in the eyes of most people they look more professional than civilian（百姓的）clothes．People have become conditioned to expect superior quality from a man who wears a uniform．The television repairman who wears uniform tends to inspire more trust than one who appears in civilian clothes．Faith in the skill of a garage mechanic is increased by a uniform．What easier way is there for a nurse, a policeman, a barber, or a waiter to lose professional identity（身份）than to step out of uniform?

　　Uniforms also have many practical benefits．They save on other clothes．They save on laundry bills．They are tax-deductible（可减税的）．They are often more comfortable and more durable than civilian clothes.

　　Primary among the arguments against uniforms is their lack of variety and the consequent loss of individuality experienced by people who must wear them．Though there are many types of uniforms, the wearer of any particular type is generally stuck with it, without change, until retirement．When people look alike, they tend to think, speak, and act similarly, on the job at least.

　　Uniforms also give rise to some practical problems．Though they are long-lasting, often their initial expense is greater than the cost of civilian clothes．Some uniforms are also expensive to maintain, requiring professional dry cleaning rather than the home laundering possible with many types of civilian clothes.

56．It is surprising that Americans who worship variety and individuality _______.

　    A．still judge a man by his clothes

　    B．hold the uniform in such high regard

　    C．enjoy having a professional identity

　    D．will respect an elevator operator as much as a general in uniform

57．People are accustomed to think that a man in uniform _______.

　    A．suggests quality work

　    B．discards his social identity

　    C．appears to be more practical

　    D．looks superior to a person in civilian clothes

58．The chief function of a uniform is to _______.

　    A．provide practical benefits to the wearer

　    B．make the wearer catch the public eye

C．inspire the wearer’s confidence in himself

　    D．provide the wearer with a professional identity

59．According to the passage, people wearing uniforms _______.

　    A．are usually helpful

　    B．have little or no individual freedom

　    C．tend to lose their individuality

　    D．enjoy greater popularity

60．The best title for this passage would be _______.

　    A．Uniforms and Society

　    C．Practical Benefits of Wearing a Uniform

　    D．Advantages and Disadvantages of Uniforms
