that goes across the continent. We are traveling by train. Out the windows, we think in the passing scene
of cars on nearby highways, of children waving at a crossing , of cattle feeding on a distant hillside, of
smoke pouring from a power plant, or row upon row of corn and wheat, of flat lands and valleys, of
mountains and rolling hills, of city skylines and village halls.
But uppermost in our minds is the final destination. On a certain day at a certain hour, we will pull into
the station. Bands will be playing and flags waving. Once we get there, so many wonderful dreams will
come true and the pieces of our lives will fit together like a completed jigsaw puzzle. How restlessly we
pace the aisles, condemning(谴责)the minutes for loitering(虚度)- waiting, waiting, waiting for the
station.
"When we reach the station, that will be it!"we cry. "When I"m 38." "When I buy a new 450SL
Mercdes Benz!""When I put the last kid through college.""When I have paid off the debt!" "When I get
a promotion.""When I reach the age of rement, I shall live happily ever after!"
Sooner or later, we must realize there is no station, no one place to arrive at once and for all. The
true joy of life is the trip. The station is only a dream.It constantly outdistances us.
"Relish(appreciate) the moment" is a good motto, actually it isn"t the burdens of today that drive man
mad. It is the regret over yesterday and the fear of tomorrow. Regret and fear are twin thieves who rob
us of today.
So stop pacing the aisles and counting the miles. Instead, climb more mountains, eat more icecream,
swim more rivers, watch more sunsets, laugh more and cry less. Life must be lived as we go along.
Then the station will come soon enough.
B. To let people enjoy the scenery.
C. To introduce an actual trip of his.

books. Doctors are starting to find more and more information that suggests a connection between
exercise and brain development. Judy Cameron, a scientist at Oregon Health and Oregon Health and
Science University, studies brain development. According to her research, it seems that exercise can
make blood vessels(管), including those in the brain, stronger and more fully developed. Dr. Cameron
claims this allows people who exercise to concentrate better. As she says, "While we already know that
exercise is good for the heart, exercise can really cause physical changes in the brain."
The effects of exercise on brain development can even be seen in babies. Babies who do activities
that require a lot of movement and physical activity show greater brain development than babies who
are less physically active. With babies, even a little movement can show big results. Margaret Barnes,
a pediatrician(儿科医生), believes in the importance of exercise. She thinks that many learning
disabilities that children have in elementary school or high school can be traced back to a lack of
movement as babies. "Babies need movement that stimulates their five senses. They need to establish a
connection between motion and memory. In this way, as they get older, children will begin to associate
physical activity with higher learning," says Margaret.
Older people can beef up their brains as well. Scientists from 11 universities studied a group of
seniors ranging in age from seventy to seventy-nine. Their study showed a short-term memory increase
of up to 40 percent after exercising just three hours a week. The exercise does not have to be very
difficult, but it does have to increase the heart rate. Also, just like the motion for infants (婴儿), exercise
for older people should involve some complexity. Learning some new skills or motions, such as with
yoga or tai-chi, helps to open up memory paths in the brain that may not have been used for a long time.
For most people, any type of physical activity that increases the heart rate is helpful. The main goal is
to increase the brain"s flow of blood. And your brain can benefit from as little as three hours of exercise
a week.

good grades can bring them cash and luxury gifts.
In at least a dozen states this school year, students who bring home top marks can expect more than just
thankfulness.
The most ambitious experiment began in September, when seven states - Arkansas, Alabama,
Connecticut, Kentucky, Massachusetts, Virginia and Washington-won spots in an Mobil-funded
program that, in most cases, pays students $100 for each passing grade on advanced placement (AP)
college-prep exams.
It"s an effort to get low-income and minority students interested in the courses, says Tommie Sue
Anthony, president of the Arkansas Advanced Initiative for Math and Science. "We still have students
who are not sure of the value, who are not willing to take the courses," she says. "Probably the motivation will make a difference with those students."
Gregg Fleisher of the National Math and Science Initiative, which runs the seven-state program, says
the effort is modeled on a program adopted by Dallas in the 1995-96 school year that saw AP
course-taking jump obviously. That program is now statewide.
While many educators would be against offering kids cash for good grades, Fleisher and others say
the idea is simple: "It"s an encouragement to get them to basically make the right decision and choose a
more strict class," he says. "This teaches them that if they work at something very hard and have a lot of
support, they can do something they didn"t think they could do."
An analysis of the Texas program last month by Cornell economist C. Kirabo Jackson found that it
linked to a 30% rise in the number of students with high SAT and ACT scores and an 8% rise in
college-going students.(Notes: 1.SAT: 美国学术能力评估考试;2. ACT: 美国大学入学考试.)
B .A new motivation for students.
C. Good grades deserves gratitude.
D. Success makes a difference.
B. To help poor students to keep on with education.
C. To get relatively poor students interested in their studies.
D. To make an effort to raise the value of money.
B. The program didn"t have any effect on student"s achievements.

D. The program was probably first adopted by Dallas.
B. makes everything possible
C. helps students choose right classes

can make your child feel angry, hurt, or misunderstood by what you say without realizing it yourself. It is
important to give your child the space he needs to grow while gently letting him know that you you"ll still
be there for him when he needs you.
Expect a lot from your child, just not everything.Except for health and safety problems, such as drug
use or careless driving; consider everything else open to discussion. If your child is unwilling to discuss
something, don"t insist he tell you what"s on his mind. The more you insist, the more likely that he"ll clarn
up. Instead , let him attempt to solve(解决)things by himself. At the same time, remind him that you"re
always there for him should he seek advice or help. Show respect for your teenager"s privacy (隐私).
Never read him his mail or listen in on personal conversations.
Teach your teenager that the family phone is for the whole family. If your child talks on the family"s
telephone for too long, tell him he can talk for15 minutes, but then he must stay off the phone for at least
an equal period of time. This not only frees up the line so that other family members can make and
receive calls, but teaches your teenager moderation(节制). Or if you are open to the idea, allow your
teenager his own phone that he pays for with his own pocket money or a part -time job

You"ve probably seen a Venus" flytrap -- a small plant, which grows 6 to 8 inches tall in a container. At the end of its stalks (茎) are leaves that act like traps (陷阱). Inside each trap is a lining of tiny hairs. When an insect lands on them, the traps suddenly shut. Over the course of a week or so, the plant feeds on its
catch.
The Venus" flytrap is just one of more than 500 species of meat-eating plants, says Barry Meyers-Rice, the editor of the International Carnivorous Plant Society"s Newsletter. He states although you might have
read some science-fiction stories, no meat-eating plant does any danger to humans.
Barry says a plant is meat-eating, only if it does all four of the following: "attract, kill, digest, and absorb"
some form of insects. Meat-eating plants look and act like other green plants -- well, most of the time.
All green plants make sugar to produce food. What makes meat-eating plants different is their special
leaves, which need insects for one reason: nitrogen (氮). Nitrogen is a nutrient that they can"t obtain any
other way. Why?
Almost all green plants on our planet get nitrogen from the soil. Meat-eating plants can"t. They live in
places where nutrients are hard to get from the soil because of its acidity. So they"ve come to rely on
getting nitrogen from insects and small animals. In fact, nutrient-rich soft is poisonous to meat-eating plants. Never fertilize (施肥) them! But don"t worry, either, if they never seem to catch any insects. They can
survive, but they"ll grow very slowly.
B. is a kind of plant which gets hungry easily
C. can trap and feed on some form of insects
D. can only grow 6-8 inches tall
B. all green plants get nitrogen from the soil
C. meat-eating plants endanger humans in science-fiction stories
D. the nutrient-poor soil is beneficial to meat-eating plants
B. probably because the supply of nitrogen is cut off
C. simply because they can"t absorb nitrogen from the soil
D. and then they will die slowly
B. It"s hard to get nutrients in the soil when acidity is high.
C. The Venus" flytrap eats flies to get nutrient from them.
D. Green plants make sugar at night.
Singing are the pupils of the remote Beau-Roc primary school in Haiti. One of them plays a guitar
made from an empty oil tin. Their headmistress, Emile Jean-Noel, is one of the few women school
principals in the country.
Over 70 % of Haitian population live below the poverty line with inadequate food, water, schools,
or housing. To reduce the hunger that prevents learning and to encourage parents to send their children
to school, meals are provided by the World Food Programme.
"We are so cut off we have many difficulties," comments Emile, adding that finding chalk, school
books and other materials is practically impossible. Emile tries to encourage those around her to make
use of all available resources. Her efforts are bearing fruit. One of her successes was convincing local
women to contribute to their children"s schooling and increase their own income by selling embroidery
(刺绣) and other handicrafts.
Recent political instability has meant that the country has not invested in education for ten years.
Enrolment(入学) is a mere 44 per cent and a little less than a half of those entering primary school finish
it. Less than a third of these go on to secondary school. In rural areas it is not rare to find 17- and
18 year-olds in primary school. Beau-Roc has only 4 teachers for 260 pupils. Emile works constantly
to improve her pupils"environment. Under her direction, a local worker is now constructing a storehouse
for the food delivered regularly by the World Food Programme.
Not only is Emile"s salary too little, but she receives it irregularly. For her, transport is a real headache. She lives five kilometers away and has to take a privately-owned bus, costing more than she can afford.
"The decision to be a rural teacher in Haiti should not be taken lightly", Emile comments. "With all the
sacrifices and risks it requires, only those who are really cut out for teaching should do it." Nevertheless,
Emile loves her job. "I always feel at home with the children and, the parents understand what I"m doing."
