just a preference - or even the result of late-night studying or instant messaging - but is rooted in their
biological rhythms (节律). All of this would be little more than an interesting observation except that most
high schools start so early, and so many teenagers are having a hard time staying awake.
A recent article in The Times cited a National Sleep Foundation survey in which more than a quarter
of the students reported that they fell asleep in class at least once a week. Researchers say this is true
because youngsters - beginning around age 12 until they reach their mid-20s-only start producing
melatonin, the sleep-inducing hormone (荷尔蒙), around 11:00 pm and that production lasts until about 7:00 am. In adults, melatonin lasts to around 4:00 am. Trying to wake up a teenager before 7:00 am is
like trying to awake an adult before 4:00 am.
The obvious remedy (补救) would be for high schools to start later-well, after 8:00 am. A handful of
schools that have switched have reported beneficial results. School officials in Minneapolis say that
attendance improved and students" grades rose slightly after they changed to start at 8:40 am several
years ago. In Wilton, Conn., where the high school start time was pushed back to 8:20 am from 7:35 am,
teachers and parents reported better student behavior and greater alertness (活泼). Surveys of students
in both districts indicated that they did not use the later starts as an excuse to go to bed later.
Numerous districts have considered the idea of later high school hours, only to drop it because of
fierce adult opposition. Coaches complain that the later classroom hours in the afternoon would take time
from their training programs and teams" success. School bus companies would be forced to change their
schedules. And many parents complained that they would have to adjust their own schedules.
Many schools officials say more research is needed. We"re all for that and for remembering that the
goal is to educate youngsters-and for that they need to be awake.
B. they waste too much rest time sending instant messages
C. they prefer to stay in bed rather than get up early
D. they have to study till late at night
B. youngsters sleepy before 7:00 am
C. adults sleepy after 4:00 am
D. adults awake after 4:00 am
B. later high school start time made students go to bed late
C. students don"t go to bed late even though they have later high school hours
D. later high school start time is a very effective measure

recent study has shown that these slightly fat birds not only fly nonstop for long periods of time during
their annual migration, but do so at record speeds.
The brown migratory birds (候鸟) that are about the size of a pigeon (鸽子) spend their summers in
Eastern Europe and winters in Central Africa, a distance of about 2,800 to 4,000 miles. In May 2009, a
team of researchers led by Dr. Raymond Klaasen from Sweden"s Lund University fitted ten Great Snipes with tiny geo-locating devices (装置) that allow scientists to figure out when and where the birds travel,
and let them loose. The following year they found three of the birds and took back the devices. What
they discovered was quite stunning.
All three birds had flown nonstop to Central Africa in August of 2009-one had flown 4,225 miles in
just 3.5 days. The second one had covered a distance of 3,833 miles in three days, while the third had
managed to fly 2,870 miles in a mere 48 hours or two days. Even more surprising was that these birds
had traveled at speeds that averaged about 50 miles per hour-making it the fastest known migration ever.
While many birds migrate longer distances, they do so over a period of a few months, resting and
feeding in between. However, despite the fact the Great Snipe has plenty of opportunities, it does not
stop. And they do the entire flight with their own power, with no assistance from the wind. The tiny bird
is able to make this unbelievable direct flight because of all the fat it gradually gathers in its body, which it
then uses as fuel.
Native no North Eastern Europe, Great Snipes live in marshlands and wet meadows (沼泽地和湿草地). But they are also on the list of endangered animals because of loss of habitat.
B. A recent research on endangered birds
C. A unique migration route of birds
D. An unusual species of migratory bird
B. worrying
C. disappointing
D. fascinating
B. They could fly about 1,200 miles a day
C. The third flew the slowest among the three.
D. They started their journey from Central Africa
B. fly with the help of the wind
C. use the fat in their body as fuel
D. sometimes take the opportunity to rest
B. explanatory
C. novelistic
D. poetic

does not learn by being corrected all the time:if corrected too
much, he will stop talking. He notices a thousand time 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
learning to do all the other things they learn to do without being
taught to walk, run, climb, whistle, ride a bicycle, compare(比
较) 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 unless it was pointed out to him,or corrcet
it unless he was made to. Let him work out,with the help of other
children if he wants it,what this word says,what the answer is to
that problem, whether this is a good way of saying or doing this or
not.
If it is a matter of right answer, as it may be in mathematics
of science, give him the answer book. Let him correct his own
paper. Why should our teachers waste time to do such routine
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 they know or do not
know.

Red Dwarf stars (红矮星) can range in size from a hundred
times smaller than the sun, to only a couple of times smaller.
Because of their small size these stars burn their fuel very slowly,
which allows them to live a very long time. Some red dwarf stars
will live trillions of years before they run out of fuel.
Then why are red dwarf stars red? Beacuse red dwarf stars
only burn a little bit of fuel at a time, they are not very hot
compared to other stars. Think of a fire. The coolest part of the
fire at the top of the flame glows red, the hotter part in the middle
glows yellow, and the hottest part near the fuel glows blue. Stars
work the same way. Their temperatures determine what color they
will be. Thus we can determine how hot a star is just by looking at
its color.
Like the Sun, these medium(中等的) -sized stars are yellow
because they have a medium temperature. Their higher
temperature causes them to burn their fuel faster. This means they
will not live as long, only about 10 billion years or so. Near the
end of their lives, these medium-sized stars swell up becoming
very large. When this happens to the Sun it will grow to engulf(吞
没) even the Earth. Finally they shrink again, leaving behind
most of their gas. This gas forms a beautiful cloud around the star
called a Planetary Nebula(行星状星云) .
When will the Sun expand into a giant, and then shrink
leaving behind a planetary nebula?
Don"t worry. The sun is only about 5 billion years old. It still
has another 5 billion years before it will expand, and then turn
into a planetary nebula.
The Sun is so hot that when it dies, it will take a long time to
cool off. The sun will die in about 5 billion years, but it will still
glow for many billions of years after that. As it cools, it will be
what is called a white dwarf star. Finally, after billions maybe
even trillions of years, it will stop glowing, at that point it will be
what we call a black dwarf star. There are still no black dwarf
stars in the Universe.
B. Because they don"t move around.
C. Because they are cool.
D. Because they reflect light like the moon.
B. Why red dwarf stars burn a little fuel.
C. Why red dwarf stars are red.
D. How temperature determines the color.
B. Become larger.
C. Keep the same.
D. Grow high.
B. Yellow Stars
C. Planetary Nebula
D. Star Temperature

research will be 4 to our society. Thus, there should be a balance 5 the government whether or
not to 6 scientific research and development. 7 the scientific research is a job 8 , it is hard for

public. No one at that time was able to 18 that this fantastic idea would lead to a 19 revolution
for Physics. 20 , free thinking without limit can encourage creativity to some extent (从某种程度上).
This is of great importance to the scientific research.

from overheating: move it to a cooler spot. All you have to do is to
send a few comets (彗星) in the direction of Earth, and its orbit
will be changed. Our world will then be sent into a safer, colder
part of the solar system.
This idea for improving our climate comes from a group of US
National Aeronautics and Space Administration( NASA) engineers
and American astronomers. They say their plan could add another
six billion years to the useful lifetime of our planet-effectively
doubling its working life.
The plan put forward by Dr Laughlin, and his colleagues Don
Korycansky and Fred Adams, needs carefully directing a comet of
asteroid (小行星) so that it passes close by our planet and sends
some of its gravitational energy to Earth.
"Earth"s orbital speed would increase as a result and we
could move to a higher orbit away from the Sun," Laughlin said.
Engineers would then direct their comet so that it passed
close to Jupiter or Saturn. The comet would pick up energy from
one of these giant planets. Later its orbit would bring it back to
Earth, and the process would be repeated.
In the short term, the plan provides an ideal way to global
warming, although the team was actually concerned with a much
greater danger. The sun is certain to heat up in about a billion
years and so "seriously compromise" our biosphere (生物圈)-by
cooking us.
That"s why the group decided to try to save Earth.
The plan has one or two worrying aspects, however. For a
stairt, space engineers would have to be very careful about how they
directed their asteroid or comet towards Earth. The smallest
miscalculation (误算) in orbit could fire it straight at Earth-with
deadly results.
There is also the question of the Moon. As the scientific
American magazine points out, if Earth was pushed out of its current
position it is "most likely that the Moon would be stripped away
from Earth," it states. This would change our planet"s climate.
B. 6 billion
C. 18 billion
D. 24 billion
B. Earth"s working life is coming to an end soon.
C. Earth will become too hot for mankind to keep alive.
D. The moon is moving farther and farther away from Earth.
B. benefit
C. share
D. endanger
B. The comet might hit Earth and man might lose the moon.
C. The comet might hit Jupiter or Saturn and never return toEarth.
D. Earth"s working life might be greatly shortened.
