and believe they need lots of exercise. They can actually be quite
lazy! Greyhounds are good at fast races but not long-distance run-
ning. They do need regular exercise but they like to run for a short
burst and then get back on the bed or a comfortable seat. Another
misunderstanding is that greyhounds must be aggressive (好斗的)
because they are big in size. In fact greyhounds love people and are
gentle with children.
Greyhounds can live for 12~14 years but usually only race for
two or three years, and after that they make great pets. They don"t
need a lot of space,don"t make a lot of noise,and don"t eat a lot for
their size.
Normally, greyhounds can be as tall as 90cm. There is, however,
a small-sized greyhound, which stands only 33cm. Greyhounds
come in a variety of colors. Grey and yellowish-brown are the most
common. Others include black, white, blue, red and brown or a mix
of these.
Greyhounds have smooth body coats ,low body fat and are very
healthy. Because they"re slim (苗条的)they don"t have the leg
problems like other dogs with the same height. But they do feel the
cold ,especially since they would much rather be at home in bed
than walking around outside.
B. to let people know more about greyhounds
C. to explain why greyhounds are aggressive
D. to describe greyhounds of different colors
B. like staying in bed all day
C. make the best guard dogs
D. need some exercise outdoors
B. They live a very long life.
C. They can run races for some time.
D. They are quiet and easy to look after.
B. to keep it warm
C. to take special care of its legs
D. to take it to animal doctors regularly

terfly Man, "his face would break into a smile. The title suits him.
And he loves it.
Arthur Bonner works with the Palos Verdes blue butterfly (蝴
蝶) ,once thought to have died out. Today the butterfly is coming
back-thanks to him. But years ago if you"d told him this was what
he"d be doing someday,he would have laughed," You"re crazy. "As
a boy,he used to be "a little tough guy on the streets". At age thirteen,
he was caught by the police for stealing. At eighteen ,he land-
ed in prison for shooting a man.
"I knew it had hurt my morn," Bonner said after he got out of
prison. "So I told myself I would not put my mom through that pain
again. "
One day he met Professor Mattoni, who was working to rebuild
the habitat(栖息地) for an endangered butterfly called El Segundo
blue.
"I saw the sign" Butterfly Habitat" and asked, " How can you
have a habitat when the butterflies can just fly away?" "Bonner recalls.
"Dr. Mattoni laughed and handed me a magnifying glass (放
大镜) ," Look at the leaves. " I could see all these caterpillars (蝶的幼
虫)on the plant. Dr. Mattoni explained, "Without the plant,
there are no butterflies. ""
Weeks later, Bonner recei.ved a call from Dr. Mattoni, who told
him there was a butterfly that needed help. That was how he met the
Palos Verdes blue. Since then he"s been working for four years to
help bring the butterfly back. He grows astragalus, the only plant
the butterfly eats. He collects butterflies and brings them into a lab
to lay eggs. Then he puts new butterflies into the habitat.
The butterfly"s population, once almost zero, is now up to 900.
For their work, Bonner and Dr. Mattoni received lots of awards. But
for Bonner,he earned something more:he turned his life around.
For six years now Bonner has kept his promise to stay out of
prison. While he"s bringing back the Palos Verdes blue, the butterfly
has helped bring him back, too.

flatbed truck being driven down the street?
Answer:A 60-ton whale on a flatbed truck exploding and rai-
ning blubber( fat of whales) all over the sidewalk.
That"s what happened in Taiwan recently,when a dead sperm
whale being shipped to the Halobios Research Centre for an autopsy
(尸体解剖) developed an extremely bad case of gas and blew up
before it reached its destination.
The whale was found alive on a Taiwan beach last weekend,
and died shortly after it was discovered. Since the 56-foot whale was
the largest whale ever beached on Taiwan"s shores,scientists wanted
to study it and perform an autopsy for educational purpose.
Obviously,too much time passed between when the animal died
and the time it was set to be moved to the autopsy location,because
it had already started to go bad. When things rot,they give off gases
as a by-product. In the whale"s case,the gases were trapped in its
belly. The pressure inside the rotting creature grew so much that it
popped like an over-filled balloon. Unfortunately,it was on a truck in
the middle of the city of Taiwan at the time ;cars and shops lining the
street were covered with whale bits and juices,much to their owners"
discouragement.
According to news reports,traffic was tied up for hours while of
ficials tried to clean up the streets.
Newspaper editors worldwide were probably smiling to them-
selves,since they had a ready-made headline; several reports about
the incident were titled " There She Blows ! " after the famous line
from the book Moby Dick.
B. sell newspapers
C. attract readers
D. give an immediate answer
B. the long transport of the creature from the beach to the centre
C. the extremely busy traffic in the streets it passed by
D. the quick process of rotting of the animal
a. The whale was set to a flatbed truck.
b. The whale was discovered.
c. The whale exploded.
d. The whale died.
B. d;c;b;a
C. b;d;a;c
D. d;b;a;c
B. Moby Dick is the name of a woman writer.
C. All the newspapers reported the story under the same title.
D. The title" There She Blows ! " is taken from the book MobyDick.
is tested again and again. But there are two tests that are more
important than all the others.
The first is called the" tank test". A modern airplane must fly
very high in the sky. Air must be pumped into the plane so that the
passengers can breathe. The metal structure(结构) of the plane has
to be very strong for this reason. When the plane is filled with air,
the air presses against the skin of the plane inside. The pressure (压
力) on a small window is like a huge foot that is trying to get out. If
a small part of the plane were to fail,the plane would explode in the
sky. To test the structure of the plane, the plane is lowered into a
huge tank or container of water. Then it is filled with air. The pressure
inside the plane is greater than it ever will be when it is high
up in the air. Finally,there is an explosion. This does not cause so
much damage inside the water tank as it would anywhere else.
Engineers can discover which part of the plane has broken. Then that
part is made stronger.
The most dangerous test happens when the new plane is going
through test flights in the air. The test pilot must find out exactly
what happens when the engines(发动机) are all shut off at once.
The plane begins to fall like a stone. It is the pilot"s job to find out
how he can get control of the plane again. These two tests are
examples of how planes are made safe before they ever carry passengers.
B. the strength of the plane structure
C. the pressure inside and outside the plane
D. the power of the airplane engines
B. It will be made stronger.
C. It will be filled with water.
D. It will be tested by pilots.
B. The pilot may lose control of the plane.
C. The engines may be damaged.
D. Too much air may get into the plane.
B. The Importance of Flying Safely.
C. The Danger of Testing Airplanes.
D. How Airplanes Are Made and Tested.
long missions on the International Space Station(ISS). ISS crewmembers usually live in space for at
least a quarter of a year. They work five days on and two days off to mimic the normal way they do things on Earth as much as possible . Weekends give the crew valuable. Weekends give the crew valuable time
to rest and do a few hours of housework. They can communicate with family and friends by email ,
internet phone and through
Private video conferees.
While astronauts cannot go to a baseball game or a movie in orbit, there are many familiar active tics
that they can still enjoy . Before a mission. The family and friends of each ISS crewmember put together
a collection of family photos, messages, videos and reading material for
The astronauts to look at when they will be floating 370 kilometers above the Earth. During their mission,
the crew also receives care packages with CDs, books, magazines, photos and letters . And as from early 2010, the internet became available on the ISS , giving astronauts the chance to do some "web surfing (冲浪)"in their personal time. Besides relaxing with these more common entertainments, astronauts can
simply enjoy the experience of living in space.
Many astronauts say that one of the most relaxing things to do in space is to look out the window and
stare at the universe and the Earth"s vast land mass and oceans.

aspirin had a reduced death rate ,especially from heart disease.
The research,based on data from a major trial that has tracked almost 80,000 women since 1976,
found that women who reported using aspirin on a regular basis had a 25 percent lower risk of death
from any cause than women who didn"t take the drug.
The risk of death from cardiovascular (心血管的) disease was 38 percent lower for aspirin users,
and there was also a 12 percent reduction in cancer deaths that took effect after a decade of aspirin
use, the researchers found in their report based on the Nurses" Health Study.
However,an accompanying editorial in the journal cautioned that the results were open to debate
and far from definitive.
The dissenting (持异议的) editorial was based on results of an earlier trial by the Women"s Health
Study, which followed almost 40,000 women for 11 years and found no reduction in overall deaths.
Therefore,the new findings" cannot overcome the accumulated evidence that aspirin is not particularly
effective for the primary prevention of death from cardiovascular disease in women. "
" This is a complicated issue , " said Dr. Andrew T. Chan, leading author of the new report. "We
understand that aspirin has potential health benefits,but who would aspirin therapy(疗法) be appropriate
for? There are areas of disagreements that need further study before that question can be answered" ,
Chan said. But there is information from the two large studies and other trials that can help guide women
and their physicians,he said. And anyone who is thinking about daily aspirin should really talk with doctors about the benefits and risks.
B. cancer
C. lose of memory
D. aspirin side effects
B. Which of the two researches is really reliable?
C. Who will do the further study in this area?
D. Who are proper for this treatment?
B. The earlier one.
C. Neither.
D. Both.
B. start immediately with the help of their physicians
C. concentrate on the benefits instead of the risks
D. turn to their physicians for only the benefit it has
B. To introduce two controversial researches.
C. To draw a final conclusion on the debate.
D. To help women live longer and healthier.
