are quizzed about their child’s physical activity level describe their children as fairly active.But a new study of nearly 2,000 British school children suggests that many parents overestimate the amount of physical
activity their children are really getting.
The researchers equipped 1,892 British school children, ages 9 and 10, with accelerometers that
measure all physical activity during a given time period.The research, known as the Speedy study
collected the exercise data from children at 92 schools in Norfolk, England, between April and July 2007.
A child was regarded inactive if he or she recorded less than an hour a day of physical activity.
Although the majority of children studied were getting enough physical activity, a_sizable_minority_of_
children_were_not.Overall,39 percent of girls and 18 percent of boys studied were getting less than an
hour of physical activity each day.
But if you asked the parents of the inactive children to describe their child’s activity level, the vast
majority-80 percent-described their children as fairly or very physically active, according to the findings
published in the American Journal of Preventive Medicine.Interestingly, the children themselves had
more awareness about their lack of physical activity.Overall,40 percent of children overestimated their
physical activity.
But it wasn’t the parents of overweight children who were most likely to guess wrong about physical
activity levels.The parents who were most out of touch about their child’s physical fitness were more
likely to have children who were slim.Parents of girls were also more likely to overestimate physical
activity.The researchers noted that parents should be educated about the importance of physical activity
for children even if the child is not overweight.
“Parents of slim children appear to assume that their children are adequately active, ” the study
authors reported.“Increasing awareness regarding health benefits of physical activity beyond weight
control might help have a correct idea of physical activity levels and encourage behavior change.”
1. According to the Speedy study, what kind of children can be judged physically inactive?
A. Slim children.
B. Children with less than an hour a day of physical activity.
C. Overweight children.
D. Children out of touch with their parents for a long time.
2. What does the writer probably mean by saying “a sizable minority of children were not” in Paragraph 3?
A. The amount of children’s physical activity is far from the writer’s satisfaction.
B. Only a small number of children were not getting enough physical activity.
C. A small number of children didn’t overestimate their physical activity.
D. The minority of children were not studied at all.
3. The passage is intended to________.
A. encourage parents to fairly judge their children’s physical activity levels
B. persuade parents to keep an eye on their children’s weight
C. urge children to wear accelerometers during exercise
D. advise parents to keep in touch with their children

TV program Seven Up?It started following the lives of a group of children in 1973.We first meet them
as wideeyed sevenyearolds and catch up with them at sevenyear intervals:nervous 14yearolds, serious
21yearolds and then grownups.
Some of the stories are inspiring, others sad, but what is interesting in almost all the cases is the way
in which the children’s early hopes and dreams are shown in their future lives.For example, at seven, Tony
is a lively child who says he wants to become a sportsman or a taxi driver.When he grows up, he goes on
to do both.How about Niki?She says, “I would like to find out about the moon.” And she goes on to
become a space scientist.As a child, softspoken Bruce says he wants to help “poor children” and ends up
teaching in India.
But if the lives of all the children had followed this pattern, the program would be far less interesting
than it actually was.It was the children whose childhood did not prepare them for what was to come that
made the program so interesting.Where did their ideas come from about what they wanted to do when
they grew up?Are children influenced by what their parents do, by what they see on television or by
what their teachers say?How great is the effect of a single important event?Many film directors,
including Steven Spielberg, say that an early visit to the cinema was the turning point in their lives.Dr
Margaret McAllister, who has done a lot of research in this area, thinks that the major factors are parents, friends and their wider society.
1. What does the text mainly discuss?
A. New ways to make a TV program interesting.
B. The importance of TV programs to children.
C. Different ways to make childhood dreams come true.
D. The influence of childhood experience on future lives.
2. What does the underlined word “influenced” mean in the last paragraph?
A. Impressed.
B. Improved.
C. Affected.
D. Attracted.
3. What are the examples in Paragraph 2 meant to show?
A. Many people’s childhood hopes are related to their future jobs.
B. There are many poor children in India who need help.
C. Children have different dreams about their future.
D. A lot of people are very sad in their childhood.
4. Spielberg’s story is meant to show that________.
A. going to a movie at an early age helps a child learn about society
B. a single childhood event may decide what one does as a grownup
C. parents and friends can help a child grow up properly

than the white area of the zebra and under the black stripes there are special layers of fat for protection.
Hot air then rises off the black stripes, forcing colder air down around the white areas, cooling the zebra
down. This, however, is just a theory. The stripes can also confuse predators (食肉动物) when zebra
stay with other animals in great numbers.
Zebras have excellent hearing and eyesight and can run at a speed of up to 35 miles per hour
(56 kilometers per hour). They also have a powerful kick that can cause serious injury to a predator, like
a lion, or an African wild dog. Usually the lead male of the herd stays at the back of the group to defend
against predators if necessary, while the females and youngsters run from danger.
Zebras are herbivores and feed mostly on grasses, although they also might eat the leaves and stems (茎) of bushes a bit. They eat grasses for many hours each day, using their strong teeth. Spending so
much time chewing wears the zebra"s teeth down, so their teeth keep growing all their lives. As the dry
season arrives and the grasses die back, zebra herds travel to find more food and water holes for
drinking. Most zebras have no specific territories. They travel from place to place, never staying in one
area very long.
B. The black stripes help the zebra live through cold days.
C. The zebra can easily be attacked by predators.
D. The zebra always travels with other animals.
B. animals that only eat plants
C. animals that kill and eat other animals
D. animals that live in groups
B. are used all day
C. are always growing
D. are kept clean
B. Their stripes can confuse predators.
C. They can run 56 miles per hour.
D. They usually stay in one area all their lives.

young people now get on with their parents, which is the opposite of the popularly held image of
unhappy teenagers locked in their room after endless family quarrels.
An important new study into teenage attitudes surprisingly shows that their family life is more
harmonious than it has ever been in the past."We were surprised by just how positive today"s young
people seem to be about their families, "said one member of the research team."They"re expected to be
rebellious (叛逆的) and selfish but actually they have other things on their minds; they want a car and
material goods, and they worry about whether school is serving them well. There"s more negotiation
(商议) and discussion between parents and children, and children expect to take part in the family
decision-making process. They don"t want to rock the boat."
So it seems that this generation of parents is much more likely than parents of 30 years ago to treat
their children as friends. "My parents are happy to discuss things with me and willing to listen to me,"
says 17yearold Daniel Lazall."I always tell them when I"m going out clubbing. As long as they know what I"m doing, they"re fine with it." Susan Crome, who is now 21, agrees."Looking back on the last 10 years,
there was a lot of what you could call negotiation. For example, as long as I"d done all my homework,
I could go out on a Saturday night. But I think my grandparents were a lot stricter with my parents than
that."
Maybe this positive view of family life should not be unexpected. It is possible that the idea of teenage
rebellion is not rooted in real facts. A researcher comments, "Our surprise that teenagers say they get
along well with their parents comes because of a brief period in our social history when teenagers were
regarded as different beings. But that idea of rebelling and breaking away from their parents really
happened during the 1960s when everyone rebelled. The normal situation throughout history has been a
smooth change from helping out with the family business to taking it over."
B. They dislike living with their parents.
C. They have to be locked in to avoid troubles.
D. They quarrel a lot with other family members.
B. cause trouble in their families
C. go boating with their family
D. make family decisions
B. are much stricter with their children
C. careless about their children"s life
D. give their children more freedom
B. is common nowadays
C. existed only in the 1960s
D. resulted from changes in families
also shows that the difference in life expectancy (预期寿命) between rich and poor becomes
smalleramong those who live in an environment with parks and trees.
Richard Mitchell, from Glasgow University, and his colleagues, found that the gap between the
number of deaths of people on high incomes and the number of deaths of those on low incomes in green
areas was half that compared with figures relating to builtup areas.
Green spaces, classified by the researchers as "open, undeveloped land with natural vegetation",
encouraged people to walk and be more active. Exercise in these settings could have greater benefits
than exercise elsewhere, the researchers said.
The benefits potentially go beyond exercise. Studies have shown that being around green spaces can
reduce blood pressure and stress levels, and possibly help patients recover faster.
A number of researchers have looked at the effects of greenery on our wellbeing. But few studies
had looked at whether living in green areas reduced health inequalities, the Glasgow team said.
Using information from a landuse database of 2001, the researchers divided the preretirement
population of England into four groups according to income level, and five groups according to access
to green space. They then looked at death rate for 2001~2005.
They found that the inequality in death rate from all causes relating to lack of money was less in
those populations in the greenest areas compared with the figures for people living in more builtup places. They found an even stronger relationship when it came to deaths from certain diseases such as heart
conditions and stroke (中风). There was no difference, however, in deaths from lung cancer.
The researchers said that changing the physical environment was an easier way to fight against poor
health than using media campaigns or giving out information on health. "The result of the study is clear:
Environments that promote good health might be very important in the fight to reduce health
inequalities."

D. People should help to fight against health problems.
B. Green spaces promote good health.
C. Income influences health less than environment.
D. Exercise in green areas benefits people a lot.
