cases, students must take public buses and trains. After junior high school, students attend schools
based on their high school entrance examination scores. So some students travel a great distance to
attend the school.
________
The school day begins at 8: 30. Then students assemble in their homeroom classes for the day"s
studies. Each homeroom has an average of 40-45 students. Students stay in their homeroom
classrooms for most of the school day. Only for physical education, laboratory classes, or other
subjects requiring special facilities(设备) do students move to different parts of the school. Between
classes and at lunchtime, classrooms can be noisy, lively places. Some schools may have a cafeteria
(自助餐厅), but most do not. In most schools, students bring a box lunch from home, prepared by
the mother in the early morning hours.
Japanese students spend 240 days a year at school, 60 days more than American students.
Students in high schools take three years" each of the following subjects mathematics, social studies,
Japanese, science, and English. Other subjects include physical education, music, art, and moral
(道德的) studies. All the students in one grade level study the same subjects. Given the number of
required subjects, electives(选修科目) are few.
Afterschool Activities
Club activities take place after school every day. Students can join only one club, and they rarely
change clubs from year to year, so the clubs are relatively stable. Clubs are made up of sports clubs
(baseball, soccer, judo, kendo, etc. ) and culture clubs(English, broadcasting, science, etc. ). New
students usually are encouraged to select a club shortly after the school year begins in April. Clubs
meet for two hours after school each day and many clubs continue to meet during school vacations.

Obviously there are some pretty big differences between our behavior and theirs in this respect. Most
Chinese children seem to get whatever they want, from ice creams, sweets and toys to endless attention
from the adults around them.Is this a sort of spoiling or love? I wonder.
Most westerners would think it is a sort of spoiling rather than love. We think love means educating
your children and bringing them up to lead an independent life. That includes learning to accept the fact
that he can"t get everything he wants. As an adult, he will not always get the quite expensive car he hunts
for; she will not always manage to acquire the beautiful dress she longs for. So we try to teach our
children early to cope with the disappointment of not getting what they want.
I find too much such kind of love for the children can actually spoil them. To my surprise, it seems
that the life of a Chinese child is rather hard. Without doubt, the child is the very center of a whole circle
of adults, but on the other hand he or she is also expected to start studying according to adults"wishes.
Many children of my son"s age take piano lessons, painting classes and even English lessons. It looks as
if Chinese adults think that just playing without learning anything is a waste of time. So in this respect our
children appear spoiled, just because they are allowed to play. But without this sort of play how can
Western children develop such free and rich imaginations? In fact, the connection between this
imagination and the creativity is so important in the children"s future life.

human beings have been putting great effort into space research. And so far, we have achieved many
successes. But there are still numerous tasks in front of us and we should not cease trying to progress.
The international space station is an important step we should take in space exploration. It is not
only helpful but also essential. It provides a proper space environment for many experiments that we
have wanted to do for a long time. It is also a base for the observations of the earth and the universe. It
could also be an important base for later travel to the moon and Mars. In a word, if we want to explore
space more, the first thing we should do is to set up a space station.
As the space station costs a lot of money, it is hard for one country alone to establish one. The USA
seems to be the only country that has the ability to build a space station alone, and it has tried to do so,
but not very successful. So it aggregated many other countries to work on it together. Though it is still
extremely expensive, it is much cheaper than doing it alone. It is really a job that needs everyone"s effort
and will benefit everyone.
But even so, the funds needed are still a big problem. As for the USA, it seems that it has too many
things to spend its money on. Although it is the richest country in the world, it has much debt every year.
It has to make arrangements about its finance, a try to find a balance in all these issues.
B. Doubtful.
C. Critical.

D. Specific arrangements.
call it the summer learning setback. Put simply, it means the longer kids are out of school, the more they
forget. The only thing they might gain is weight. Recent studies show that children gain weight more
quickly in the summer vacation than when they are in school.
Most American schools follow a traditional nine-month calendar. Students get winter and spring
breaks and about ten weeks of summer vacation. Some schools follow a year?round calendar. They
hold classes for about eight weeks at a time, with a few weeks off in between. But many experts point
out that the number of class days in a year-round school is generally the same as in a traditional school.
Last year, a study at Ohio State University reported that year-round students did not learn any more
than other students. Lead researcher Paul von Hippel said "year-round schools don"t really solve the
problem of the summer learning setback. They simply spread it out across the year".
Across the country, research shows that students from poor families fall farther behind over the
summer vacation than other students. Experts say this can be prevented. They note that many schools
and local governments offer the programs that can help.
But calling them "summer schools" could be a problem. The director of the summer learning center
at Johns Hopkins, Ron Fairchild, recently wrote about this issue on his blog.
He said that in American culture, the idea of summer vacation is connected to the beliefs about
freedom and the joys of childhood. He said research with groups of different parents in Chicago and
Baltimore found that almost all strongly disliked the term summer school. They said it created an image
of children being forced to do work they missed during the school year.

What exactly are white lions?"They are a color variation of regular lions,"says William
Swanson,director of animal research at the Cincinnati Zoo,in Ohio.
White lions are the result of a rare color gene mutation(变异).When both a male and
a female lion carry the same white genes,there is a good chance that one or more of their
cubs(幼兽)will be born with white fur.
Not many lions carry the white mutation.In nature,it"s rare.A mutation can make an
animal"s survival more difficult.For example,being white makes it harder for the animal to
mix with its surroundings.Mutations also can cause physical problems,so those animals
generally do not survive long enough to reproduce.
But sometimes white lion cubs are born among wild lions,especially in two areas of
South Africa.
In 1975 two white cubs were spotted in the wild in South African reserve.They were
seized and sent to a zoo.Today about 500 cubs of those two white lions and a few others
known to have the white color gene live around the world in zoos,circuses,farms and private
preserves.
White lions may be extremely rare in the wild,but breeders(饲养动物的人)know how
to create more of them.This has created serious concern and debate.
White lions continue to exist only because they are inbred by people-fathers and
daughters,sisters and brothers.Scientists worry that it also will cause health issues for white
lions.
Inbreeding to create white lions as moneymaking attractions is only one concern.Another
concern is that some people want to release captive-bred(人工繁殖的)white lions into
the wild in South Africa to restore balance to the ecosystem.However,not everyone agrees
that releasing these white lions into the wild is a good idea.Dan York of Hillsdale College
has been studying white lion genetics and is worried.He says that because so many of today"s
white lions are inbred,it could spread health problems.If they breed with wild lions,they"ll
pass on the genetic problems to the wild population.
Instead of releasing captive-bred white lions,York suggests that South Africa concentrate
on protecting all of its wild lions.That would ensure the safety of the wild population of lions,
which may produce healthy white cubs in the future.

Today we tell you about some new understanding of why cutting the main branch of a plant
or tree can lead to better development.
The findings are from researchers on two_continents.Professor Prezemyslaw Prusinkiewicz
of the University of Calgary in Canada led the research with scientists from Britain and Sweden.
Their study appears in the Proceedings of the National Academy of Sciences.
Researchers have known since the 1930s that the actively growing tip of a plant produces
a hormone(荷尔蒙)called auxin(生长素).This hormone flows down the main stem.Scientists
say the auxin has an indirect effect on buds(芽)on the side of the stem to prevent branching.
T hese buds themselves also produce auxin.The research suggests that to grow,they have
to be able to export the hormone into the main stem.But the flow from the stem tip prevents
them from doing this.The researchers wanted to find out how this blocking happens.
Professor Prusinkiewicz is on leave in Australia,but he sent us an e-mail suggesting a
simple way to understand the process.Think of a major road crowded with traffic.So many
cars are on the main road that the cars on the side roads cannot enter.
The stem is like the crowded main road.The new research shows that the buds on the
side cannot export their auxin into the main stem because it is too full.But if that main shoot
is pruned(修剪),other buds below it can start exporting.They are no longer prevented from
growing.
Ottoline Leyser from the University of York says that after a plant is pruned,all the
inhibited(被抑制的)shoot tips compete with each other to grow.In doing this,the branches
influence each other"s growth.Nearby shoot tips are more likely to affect each other than those
that are far apart from each other.
Professor Leyser says the strongest branches grow best,wherever they may be on the
plant.The study found that the main shoot grows the best of all not because of its position at
the top of the plant,but mostly because it got there first.
B.Africa and Europe
C.North America and Europe
D.Australia and Europe
B.plant buds
C.the leaves of a plant
D.the roots of a plant
B.be protected
C.be watered as much as possible
D.be given much auxin
A.Researchers have recently found out that the growing tip of a plant produces hormones.
B.Auxin has a direct effect on buds to keep branches from growing.
C.Buds on the side of the stem can’t produce hormones.
D.In order to grow,the buds on the side of the stem export the hormones into the main stem.
B.When and how to prune plants?
C.Scientists help cut the mystery behind pruning
