The great Snipe is a little shore bird-not one that would be considered a great athlete. However, a
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. |

Let children judge their own work. A child learning to talk
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
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. |
| 1. Why do the Red Dwarf stars burn their fuel very slowly? |
A. Because they are small.
B. Because they don"t move around.
C. Because they are cool.
D. Because they reflect light like the moon. |
| 2. Which of the following best expresses the main idea of Paragra-ph 2? |
A. How red dwarf stars work.
B. Why red dwarf stars burn a little fuel.

Scientists have found an unusual way to prevent our planet
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. |
| 1. If the plan is successful, Earth will have a working life of ____ years. |
A. 12 billion
B. 6 billion
C. 18 billion
D. 24 billion |
| 2. What makes the scientists plan to save Earth? |
A. A few comets are moving to the direction of Earth.
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. |
| 3. What does the underlined word" compromise" mean? |
A. provide
B. benefit
C. share
D. endanger |
| 4. What serious problems might the plan cause according to the passage ? |
A. Earth might be moved too far away and man might be frozen to death.
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. |

Planet Hunter
When Geoff Marcy was 14, his parents bought him a telescope. Every night,he would
go onto the roof outside his window to see the wonders of the sky.
" What excited me most was whether there were planets in other solar systems where life
might exist," he says. "I decided to try to find planets orbiting other stars like our Sun. "
And he did. " My fellow researcher, Paul Butler, and I found our first planet in 1995 , " Dr Marcy
says. " We worked for ten years without finding anything! But we stuck with it, and our patience
paid off. "
Since then, the two scientists have discovered 65 of the more than 100 planets found orbiting other
stars. Dr Marcy and Dr Butler also spotted the first "family" of three planets. In June 2002 they
announced another discovery: a Jupiter-like(像木星一样的) planet orbiting star 55 Cancri.
At first, the two researchers found only planets that orbit close to stars. Recently, the scientists
found planets farther out. The planet orbiting 55 Cancri is a major breakthrough: it is the first sighting
of a large gas planet about the same distance from the star as Jupiter is from the Sun.
Why is this important? Scientists think that life on Earth may exist because of two special features
(特征) in our solar system.
The first is Jupiter.
"Because it"s so big, Jupiter pulls comets (彗星) and asteroids (小行星) , or they all come and hit
the Earth. " Dr Marcy explains. "Without Jupiter, life on Earth would likely have been destroyed. "
A second feature is that Earth is a rocky planet where liquid water, which is necessary for life, can
exist. Unlike gas planets, rocky planets like Earth have surfaces where water can gather in pools and
seas, which may support life. A huge space exists between the Jupiter-like planet and two other planets
that lie close
to 55 Cancri. Is there an Earth-like planet in the space, too small for us to notice? If so, says Dr Marcy," We would have two striking similarities to our solar system: a Jupiter-like planet and an Earth-like planet. And there may be life ! " |
| 1. What can we learn about Dr Marcy from the passage? |
A. He is fond of watching Jupiter.
B. He is from a scientist family.
C. He dislikes working with Paul Butler.
D. He is interested in finding life in outer space. |
| 2. Which of the following is TRUE of the recent discovery? |
A. The planet is not as protective as Jupiter.
B. The planet is close to star 55 Cancri.
C. The planet proves to be a gas planet.
D. The planet is as large as Jupiter. |
| 3. How many planets orbiting other stars have the two scientists discovered so far? |
A. 100.
B. 69.
C. 66.
D. 65. |
| 4. Dr Marcy thinks that life may exist in the 55 Cancri system because _____ . |
A. he has found the system similar to the solar system
B. he has discovered an Earth-like planet there
C. he has discovered a rocky planet there
D. he has found signs of life in the system |
