Let children learn to judge their own work. A child learning to talk does not learn by being
corrected all the tim
e; if corrected too much, he will stop talking. He notices a thousand times
a day the difference between the language he uses and the language those around him use. Bit
by bit, he makes the necessary changes to make his language like other people"s. In the same
way, children learn to do all the other things without being taught to walk, run, climb, whistle,
ride a bicycle…They compare their own performances with those of more skilled people, and
slowly make the needed changes. But in school we never give a child a chance to find out his
mistakes and correct them for himself. We do it all for him. We act as if we thought that he
would never notice a mistake. If it is a matter in mathematics or science, give him the answer book.
Let him correct his own papers. Why should we teachers waste time in such routine(日常的)work?
Our job should be to help the child when he tells us that he can"t find the way to get the right answer.
Let the children learn what all educated persons must some day learn, how to measure their own
understanding, how to know what he does not know.

but their time is measured by a pendulum (钟摆) and is not psychological time, which leaps with little
regard to the clock or calendar. As some-one who understood the distinction observed, "When you sit
with a nice girl for two hours it seems like a minute, but when you sit on a hot stove, a minute seems like
two hours. "
Psychologists have long noticed that larger units of time, such as months and years, fly on swifter
wings as we age. They also note that the more time is structured with schedules and appointments, the
more rapidly it seems to pass. For example, a day at the office flies compared with a day at the beach.
Since most of us spend fewer days at the beach and more at the office as we age, an increase in
structured tune could well be to blame for why time seems to speed up as we grow older.
Expectation and familiarity also make time seem to flow more rapidly. Almost all of us have had the
experience of driving somewhere we"ve never been before. Surrounded by unfamiliar scenery, with no
real idea of when we"ll arrive, we experience the trip as lasting a long time. But the return trip, although
exactly as long, seems to take far less time. The novelty of the outward journey has become routine.
Thus taking a different route on occasions can often help slow the clock.
When was become as identical as identical as beads(小珠子)on a string, they mix together, and even
months become a single day. To counter this, try to find ways to interrupt the structure of your day-to
stop time, so to speak.
Learning something new is one of the ways to slow the passage of time. One of the reasons the days
of our youth seems so full and long is that these are the days of learning and discovery. For many of us,
learning ends when we leave school, but this doesn"t have to be.

That is when two American astronomers reported on their study of all the light in the universe. They said
that the universe would appear to the human eyes to be a light greenish color.
Karl Glazebrook and Ivan Baldry of Johns Hopkins University in Baltimore, Maryland, reported their
finding in January. They presented the research at a meeting of the American Astronomical Society. They
said that finding the color of the universe was not part of their more serious scientific research. They did it
for fun.
However, earlier this month, the scientists admitted making a mistake. They said their finding was
much more colorful than it should have been. They now say the light from our universe is closer to white.
It is more like a milky or creamy white color.
Their study attempted to show what people might see if they could observe the universe from far
away. The scientists found the average color by combining light from about two-hundred-thousand star
systems. Their information came from an observatory in New South Wales, Australia.
The scientists gave a number value to the colors of the different star systems. Then they added the
numbers together and found the average measurement. The scientists used this average to identify the
color of the universe. They said it was a very pretty light green. Many newspapers and television stations
reported their finding.
Other scientists and color engineers attempted to reproduce the result. Mark Fairchild of the
Rochester Institute discovered a mistake in the computer software program used by the Johns Hopkins
scientists.
When the mistake was corrected, the results changed. The new color of the universe is much less
colorful. It is very close to white.
1.The color of the universe is _______.
A. close to white
B. black
C. blue
D. light greenish
2.The two scientists found the color of the universe by _____.
A. combining light from about 200,000 star systems
B. observing at an observatory in India
C. m
aking long-term scientific researchD. using computer software programs
3.Who found the true color of the universe?
A. Karl Glazebrook.
B. Ivan Baldry.
C. Mark Fairchild
D. Johns Hopkins.
4.This passage mainly tells us _______.
A. what the color of the universe is

C. the new color of the universe is much more colorful
D. the finding of the color of the universe is difficult

Scientists have shown that teens are more active later at night than children and adults, so most teens
are probably staying up later for whatever reasons."The researchers measured the presence of the
sleeppromoting hormone (荷尔蒙) in teenagers" saliva (唾液) at different time of the day.They learned
that the hormone levels rise later at night than they do in children and adults-and remain at a higher level
later in the morning.Measuring the hormone in the saliva is a good way to show that most teens have
sleep problems, but changing school schedules isn"t the best way to fix this.Most people arguing against
changing school schedules would say that it would only cause teens to stay up and wake up later, thus
leaving them with the same problem.
The biggest problem schools would come across from changing their schedules would be the after
school and job conflicts students and teachers would meet."Teachers reported that students were more
alert, and research showed that afterschool sports and jobs would suffer.Students in that area might have
been able to deal with less time for jobs and sports somehow, but some of them have practice and earlier plans that would become conflicted if this change were to occur.Most students rarely have time to play a
sport and do homework before 9 or 10 o"clock.Opening schools later may have worked for some areas,
but the reality is often very different.
1. The meaning of the underlined word "chaotic"in the 1st paragraph is close to________.

2. Most teens have sleep problems because________.
A. they are more active than children and adults
B. school work takes up most of their time
C. their hormone levels are higher later at night
D. they probably like staying up for no reason
3. Which of the following is TRUE according to the passage?
A. There are many conflicts between students and teachers.
B. Some of the teachers have practice and earlier plans.
C. Most students are able to do sport and homework before 9?00.
D. Ways to solve students" sleep problem vary from area to area.
4. The passage mainly develops by________.

grey, research suggests.
And the under 25s who have watched color TV all their lives tend to have colorful adventures in_the_
land_of_nod.
Research from the first half of the 20th century, especially in the 1930s and 1950s, suggested that most dreams are in black and white.
But results from tests in the 1960s and later suggested that up to 80 per cent of dreams contain some
colors.
Since this period marked the transition (过渡) from blackandwhite films and TV to widespread
Technicolor (彩色印片法), an obvious explanation was that television was influencing dreams, but
differences between the studies prevented the researchers from drawing any firm conclusions.
Later studies asked subjects (实验对象) to complete dream diaries immediately they woke up, but
the earlier research used questionnaires completed in the middle of the day, so the subjects might have
simply forgotten color elements in their dreams and assumed they were grey.
To solve the problem, psychologist Eva Murzyn asked 60 subjects, half of whom were under 25 and
half over 55, to answer a questionnaire on the color of their dreams and their childhood exposure (暴露)
to films and TV.
The subjects then recorded different aspects of their dreams in a diary every morning.
She found there was no significant difference between results drawn from the questionnaires and the
dream diaries.
She then analyzed data to find out whether an early exposure to blackandwhite TV or films could still
have a lasting effect on her subjects"dreams,40 years later.
Less than five per cent of the under25s"dreams were black and white.But the over55s who had access to
blackandwhite media in their younger days reported dreaming in black and white roughly a quarter of the
time.
Murzyn said, "There could be a critical period in our childhood when watching films has a big influence on the way dreams are formed." People"s attention might be heightened during the time they are watching
TV or films.
B. the 1930s
C. the 1950s
D. the 1960s and later
B. during travelling
C. in a dream world
D. when they are thinking
B. both diaries and questionnaires were used
C. more advanced technology was used
D. subjects were given more time to record their dreams
B. the results of the previous studies on dreams couldn"t be trusted
C. older people are more likely to be influenced by TV viewing
D. the colors of TV sets are more likely to appear in viewers"dreams
B. TV viewing has different influences on different people.
C. Childhood TV viewing may determine the color of dreams.
D. Childhood TV viewing may influence a person"s later life.
