actually bring results.For example, hunters may use a hunting charm (咒语). But they also use their
hunting skills and knowledge of animals. The charm may give hunters the extra confidence they need to
hunt even more successfully than they would without it.If they shoot a lot of game (猎物), they credit
the charm for their success. Many events happen naturally without magic. Crops grow without it, and
sick people get well without it.But if people use magic to bring a good harvest or to cure a patient, they
may believe the magic was responsible.
People also tend to forget magic"s failures and to be impres
sed by its surface successes. They may consider magic successful if it appears to work only 10 per cent of the time. Even when magic fails,
people often expla
in the failure without doubting the power of the magic. They may say that the magician made a mistake in reciting the spell or that another magician cast a more powerful spell against the
magician.
Many anthropologists (人类学家) believe that people have faith in magic because they feel a need to
believe in it. People may turn to magic to reduce their fear and uncertainty if they feel they have no
control over the outcome of a situation. For example, farmers use knowledge and skill when they plant
their fields. But they know that weather, insects, or diseases might ruin the crops. So farmers in some
societies may also plant a charm or perform a magic rite to ensure a good harvest.
B. a farmer
C. a magician
D. an anthropologist
B. Magic and Farming
C. Why Magic Works?
D. Why People Believe in Magic?

The largest study of the effects of ageing on the heart has found that women"s longevity may be linked to the fact that their hearts do not lose their pumping power with age.
"We have found that the power of the male heart falls by 20-25 percent between 18 and 70 years of
age," said the head of the study, David Goldspink of Liverpool John Moores University in the UK.
"Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70,
one-third of those cells die and are not replaced in men," said Goldspink. "This is part of the ageing
process."
What surprises scientists is that the female heart sees very little loss of these cells. A healthy
70-year-old woman"s heart could perform almost as well as a 20-year-old one"s. "This gender( 性别)
difference might just explain why women live longer than men," said Goldspink. They studied more than
250 healthy men and women between the ages of 18 and 80, focusing on healthy persons to remove the
confusing influence of disease. "The team has yet to find why ageing takes a greater loss on the male heart," said Goldspink.
The good news is that men can improve the health of their heart with regular exercise. Goldspink
stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age.
B. ageing
C. long life
D. effect
B. women"s ageing process
C. the gender difference
D. hearts and long life
B. women can replace the cells that enable the heart to beat
C. the female heart loses few of the cells with age
D. women never lose their pumping power with age
B. find out the reason for ageing
C. enable your heart to beat much faster
D. prevent your cells from being lost
B. scientists are on the way to finding out why the male heart loses more of the cells
C. the team has done something to prevent the male from suffering the greater loss
D. women over 70 could lose more heart cells than those at the age of 20
opinions. But recent data has indeed shown cognitive (认知的) ability to be higher in some countries than
in others. What"s more, IQ scores have risen as nations develop-a phenomenon known as the "Flynn
effect". Many causes have been put forward for both the intelligence difference and the Flynn effect,
including education, income, and even non-agricultural labor. Now, a new study from researchers at the
University of New Mexico offers another interesting theory: intelligence may be linked to
infectious-disease rates.
[2]The brain, say author Christopher Eppig and his colleagues, is the "most costly organ in the human
body". Brainpower consumes almost up to 90 percent of a newborn"s energy. It"s clear that if something
affects energy intake while the brain is growing, the impact could be long and serious. And for vast parts of the globe, the biggest threat to a child"s body-and therefore brain-is parasitic (由寄生虫引起的) infection. These illnesses threaten brain development________________. They can directly attack live tissue, which the body must then try every means to replace. They can invade the digestive pipe and block nutritional
intake. They can rob the body"s cells for their own reproduction. And then there"s the energy channeled (输送) to the immune system to fight the infection.
[3]Using data on national "disease burdens" (life years lost due to infectious diseases) and average
intelligence scores, the authors found they are closely associated. The countries with the lowest average IQ scores have the highest disease burdens without exception. On the contrary, nations with low disease
burdens top the IQ list.
[4]If the study holds water, it could be revolutionary for our understanding of the still-confusing
variation in national intelligence scores.

with incomes below the poverty line are considered poor. Economists study the causes of poverty in
order to find solutions to the problem.
As the general standard of living in the country rises, the poverty line does, too. Therefore, even with
today"s relatively high standard of living, about 10 percent of the people in the United States are below
the poverty line.However, if these people had stable jobs, they could have an acceptable standard of
living. Economists suggest several reasons why poor people do not have jobs.
For one thing, more than half of the poor people in the United States are not qualified to work. Over
40 percent of the poor people are children.By law, children less than 16 years old cannot work in many
industries. A large number of poor people are old. Many companies do not hire people over 65 years
old, the normal retirement age.
Some poor adults do not look for jobs for a variety of personal reasons: they are sick, they do not
have any motivation, they have family problems, or they do not believe that they can find a job.
Other poor people look for a job but cannot find one. Many poor adults never went to high school.
Therefore, when they look for jobs, they have few skills that they can offer.
At the present time, the government thinks it can reduce poverty in the country in the following ways.
First, if the national economy grows, businesses and industries hire more workers.Some of the poor who
are qualified to look for jobs may find employme
nt. T
hen they will no longer be below the poverty line.Second, if society invests in the poor, the poor will become more productive.If the government spends
money on social programs, education, and training for poor people, the poor will have the skills to offer.
Then it is more likely that they can find jobs.
Finally, if the government distributes society"s income differently, it raises some poor people above
the poverty line. The government collects taxes from the non－poor and gives money to the poor. These
payments to the poor are called welfare. In 1975 over 18 million people in the United States received
welfare.
Some economists are looking for better solutions to the poverty problem. However, at the present
time, many people depend on welfare for a minimally acceptable standard of living.
B. to explain why some people live the poverty line
C. to find solutions to the problem
of povertyD. to show sympathy for those poor people
rcent of the Americans live a poor life.B. Poor people are those who live below the poverty line.
C. The poverty line rises as the general standard of living rises.
D. The poverty line tends to be at the same level.
B. they are so young that they don’t have the right to work
C. they fail to get enough education
D. they are very poor in health
B. they are not very self－confident
C. they are too young or too old to work
D. they have physical and family problems
B. welfare will enable them to be rich
C. poor people are sure to go out of the poverty line if they have chances to do business
D. employment is the best solution to the poverty problem
ago.Unlike government schools, which have very large classes of 90 children , many of
whom do not want to learn, Bridge has small classes, so pupils get a great deal of attention.
Small classes are good for teaching, but the school is always having difficulty with money
since private schools are dependent on parents paying on time.
The school has five primary classes and three nursery classes(幼儿班). As the children
progress through the school they will add another class next year. The total number of children
in the primary is about 50. The parents of Bridge children
are often higher earners than thosethat attend government schools. They want their children to have the best education available.
The school is not yet finished. The classrooms have no windows or doors. But it is very
formal and insists on children wearing uniforms(制服).Discipline is strict and the children are
well-behaved. Only English may be spoken and not the local language. Although English is
the national language and the language o
f education, government schools teach in their ownlanguage for the first three years.
School starts at 7 am and the children have to be on time. Classes are formal, but children
have to copy lots of things from the blackboard, because there are few textbooks, sometimes
only one for the teacher to use. Class work is heavy and the children have tests every week.
They also study during the holiday.
B. hope their children get the best education
C. want their children to be different
D. have no time to take care of their children
B. Teachers don"t speak English in class.
C. Children always work very hard.
D. It is free for children to attend them.
B. Textbooks are not needed.
C. Lessons are given in the local language there.
D. Life there is not easy for children.
