Passage 57

(吉林省實驗中學2007屆高三第四次模擬考試B篇)

Many deaths from home fires are the result of burns and panic, but most are caused by deadly smoke and gases. These fatal fires are often caused by such careless acts as throwing away a lighted match or cigarette, allowing rubbish to pile up, overloading electrical wires, or misuse of healing and cooking equipment.

Few families go to bed at night without first checking to make sure that the doors and windows are locked, but they overlook a very basic fire safety rule. This rule states that people should sleep with their bedroom doors closed. Nighttime fires are most serious because the family is asleep and the discovery of fire is usually too late.

A closed bedroom door gives extra protected by delaying the gases and fire, thus giving the family a few minutes to escape.

At the first sight of fire in a home, it is necessary for everyone to get out of the house, especially children and elderly persons who may need help. Not everyone flees quickly from a burning home. Children often panic and hide in closets or under beds. Being prepared or knowing what to do in case fire breaks out can mean the difference between life and death. All members of the family should know certain basic steps.

Everyone should know an escape route and second route from each room in the house. Very young children and old persons should receive careful thought when mapping out family escape plans. Both groups will need special help in escaping from home fires. A family should determine a way in which any members can sound an alarm. It is likely that fire may block hallways and prevent a person from reaching other bedrooms : Family members should be taught not to waste time getting dressed or collecting valuable possessions. Speed is necessary in escaping from fire.

Passage 56

(北京市北大附中2007年5月高三最后適應測試B篇)

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.
