insurance to help pay for medical care. The government only helps pay for some medical care for
the old and the people who are on low incomes. The problems of those who cannot afford insurance
have become an important political subject.
In Britain, when people are ill, they usually go to a family doctor first. However, people in America
sometimes go straight to an expert. Children are usually taken to a doctor who is an expert in the
treatment of children. In Britain, if a patient needs to see a specialist doctor, their family doctor will
usually recommend a specialist, which will save more time and money both for the patients and the
public fund (基金).
In Britain, doctors do not go to people"s homes when they are ill. People always make
appointments to see the doctor in the doctor"s office. In a serious situation, people call for an
ambulance. In America, hospitals must treat all seriously ill patients, even if they do not have medical
insurance. The government will then help pay for some of the cost of the medical care.

D. by increasing their income

Weiming, who has killed five and injured some others in Chengdu, Sichuan. However, such a case is
not rare.
Today, traffic accidents may have been regarded as a social problem. The car has killed and
disabled more people in its brief history than any bomb or weapon ever invented. Much of the blood
on the street flows actually from rude behavior of drivers who refuse to respect the legal and moral
rights of others. In fact, the enemies of society on wheels are rather harmless but just ordinary people
acting carelessly, you might say. But it is a principle both of law and common morality that carelessness
is no excuse when one"s actions could bring death or damage to others. A minority of the killers go
even far beyond carelessness that can be imagined.
Researchers have estimated that as many as 80 percent of all automobile accidents can be attributed
to the psychological condition of the driver. Emotional upsets can change drivers" reactions, slow their
judgment, and make them blind to the dangers that might otherwise be evident. The experts warn that
it is vital for every driver to make a conscious effort to keep his/her emotions under control.
Yet the irresponsibility that accounts for much of the problem isn"t only put upon drivers. Street
walkers regularly ignore or break traffic regulations. They are blamed in most vehiclewalker accidents,
and many cyclists even believe that they are not subject to the basic rules of the road.
Significant legal advances have been made towards safer driving in the past few years. Safety
standards for vehicles have been raised both at the point of manufacture and through regular road
inspections. In addition, speed limits have been lowered. Due to these measures, the accident rate
has decreased. But the accident experts still worry because there has been little or no improvement
in the way drivers behave. The only real and lasting solution, say the experts, is to make people believe
that driving is a skilled task requiring constant care and concentration. Those who fail to do all these
things present a threat to those with whom they share the road.
B. people usually pay no attention to law and morality when driving
C. they have caused serious psychological problems among drivers
D. the car has killed and disabled more people than any weapon in history
B. Careless people walking in the street.
C. Irresponsible auto drivers.
D. Irresponsible auto manufacturers.
B. angry and disappointed
C. objective and concerned
D. anxious and annoyed
B. help protect street walkers from car accidents
C. discuss traffic problems and possible solutions
D. warn auto drivers to refuse drunk driving

child rearing-older parents are more thoughtful, use less physical discipline and spend more time
with their children. But raising kids takes money and energy. Many older parents find themselves
balancing their limited financial resources, declining energy and failing health against the growing
demands of an active child. Dying and leaving young children is probably the older parents" biggest,
and often unspoken, fear. Having late-life children, says an economics professor, often means parents,
particularly fathers, "end up retiring much later." For many, retirement becomes an unobtainable dream.
Henry Metcalf, a 54-year-old journalist, knows it takes money to raise kids. But he"s also worried
that his energy will give out first. Sure, he can still ride bikes with his athletic fifth grader, but he"s
learned that young at heart doesn"t mean young. Lately he"s been taking afternoon naps (午睡) to
keep up his energy. "My body is aging," says Metcalf. "You can"t get away from that."
Often, older parents hear the ticking of another kind of biological clock. Therapists who work
with middle-aged and older parents say fears about aging are nothing to laugh at. "They worry they"ll
be mistaken for grandparents, or that they"ll need help getting up out of those little chairs in nursery
school," says Joann Galst, a New York psychologist. But at the core of those little fears there is often
a much bigger one: "that they won"t be alive long enough to support and protect their child," she says.
Many late-life parents, though, say their children came at just the right time. After marrying late
and undergoing years of fertility (受孕) treatment, Marilyn Nolen and her husband. Randy, had
twins. "We both wanted children," says Marilyn, who was 55 when she gave birth. The twins have
given the couple what they desired for years, "a sense of family." Kids of older dads are often smarter,
happier and more sociable because their fathers are more involved in their lives. "The dads are older,
more mature," says Dr. Silber, "and more ready to focus on parenting."
B. Older parents can take better care of their children.
C. Older parents are usually more experienced in bringing up their children.
D. Older parents can better balance their resources against children"s demands.
(Lines 7-8, Para. 1. )
B. They can"t obtain the retirement benefits they have dreamed of.
C. They can"t get full pension unless they work some extra years.
D. They have to go on working beyond their retirement age.
B. many people are young in spirit despite their advanced age
C. older parents tend to be concerned about their aging bodies
D. taking afternoon naps is a good way to maintain energy
B. Slowing down of their pace of life.
C. Being laughed at by other people.
D. Being mistaken for grandparents.
B. Not until they reached middle age did they think of having children.
C. Not until they had the twins did they feel they had formed a family.
D. They believed that children born of older parents would be smarter.
now it seems that all the hard work may have been in vain.
Scientists say there are ten other reasons why people just keep getting bigger. They say that
sleeping habits, central heating, medicines and even some pollutants (污染物) can play a role in
weight gain.
Traditionally, people have focused on diet and exercise to solve the problem. However the
scientists from top US and Canadian universities say that other things must be considered.
Lack of sleep could be partly the reason. In recent years, the average night"s sleep has dropped
from nine hours to just seven. Sleep shortage changes levels of the hormones (荷尔蒙) that control
food intake and body fat and increase hunger and appetite.
If it is too hot or too cold, we burn calories (卡路里) to cool down or heat up. But if the
temperature is just right, the calories may be turned into body fat instead.
Those who take medicine to control their blood pressure can often put on weight. Similarly, studies
have shown that going on the Pill can add to a woman"s weight.
Mother nature may also be the reason, with our body shape being partly inherited (遗传的). The
overweight are also more likely to settle with partners of a similar size. And their children are more
likely to be obese (肥胖的).
And the use of pollutants is on the rise, say the researchers. The man-made chemicals in pesticides
(***虫剂) and plastics can lead to weight gain.
Your mother"s age and your weight at birth are also important, with older woman more likely to
have obese children and underweight babies having a bigger chance of being obese in later life.
We also tend to put on weight as we get older. Finally, giving up smoking can also help pile on the
pounds.
The scientists from Yale, Cornell and Johns Hopkins said there was some evidence supporting poor
diet and lack of exercise as the main causes of obesity.
B. To take pills and avoid fatty food.
C. To sleep less to burn more calories.
D. To have less food and take more exercise.
B. Comfortable living environment.
C. Not enough physical exercise.
D. harmful chemicals in the food.
B. Unpleasant weather helps you to put on weight.
C. Obese parents are not likely to have fat children.
D. Medicine for blood pressure helps you lose weight.
B. To marry at an older age.
C. To marry a strong husband.
D. To give birth to a baby at younger age.
