about it? Take the "Mars Orbit Express"!
"Mars Orbit Express" is a space probe (探测器). It was sent towards Mars by American scientists on
August 12th, 2005. Its tasks are to study Mars" atmosphere and return photos to Earth. But before that "Mars
Orbit Express" must travel about 100 hundred million kilometers and seven months. It reached Mars" orbit (轨道) in March, 2006.
Mars and Earth have similar weight and size. However, Mars is closer to the sun than Earth. Mars is very
cold. The average temperature is below 50℃. The temperature at noon only reaches 20℃ during a Mars day.
Its atmosphere is mostly CO2. It has much sand and two moons---Phobos and Deimos.
Scientists think Earth and Mars had similar beginnings 4.6 billion years ago. But while Earth supports
millions of lives, Mars becomes bad. "Earth easily could have turned out like that." said an scientist, "It is
important for us to find out why and Mars Orbit Express should do that." "Mars Orbit Express" also would
help scientists to learn what might happen to Earth in the future. "Mars Orbit Express" would work for about
four years.
B. A red star
C. Its atmosphere
D. Its size
B. studying the weight of Mars
C. finding out distance between Earth and Mars
D. telling the time it takes to go from Earth to Mars
B. Mars is big and heavy
C. Mars is close to the sun
D. Mars" atmosphere is mainly O2.
B. A probe:to learn more about Mars
C. Mars: change of temperature
D. A probe:to tell the future of Earth

however, science stories are becoming true. More and more robots are starting to be used in factories and our
homes. These robots are different in size, shape and colour, but all of them have the same type of man-made
"brain". The robots that work in factories are called industrial robots.
These kinds of robots are cleverer and faster than the old ones. Industrial robots can do jobs that are often
boring and sometimes dangerous.
Robots are already coming into American homes, though not as quickly as they are going into factories.
We have made robots work at home. They can do some housework like cooking, or playing with people just
for fun.
These robots aren"t as friendly and clever as those in Star Wars. But their makers say, today"s home robots
can "walk" and find objects in their way, though sometimes they may knock into (撞上) those objects. They
can even carry objects, though sometimes they may drop those objects. Well, nobody is perfect. We may
laugh at home robots today,but some day they will do better than humans. We humans can only see certain
length of light, and hear certain sounds, while robots may see and hear better than we do.
In a word, robots will be widely used in our life in the future.

Changming, principal of Beijing No. 4 High School made 18 suggestions for students just starting high school
on how to get the best out of high school. Here are ten of them.
1) Read 50 books. But choose them from ten different fields.
2) Help a person. Look for a classmate, an elderly person, in fact anyone who could benefit (获益) from your
help. You"ll find you benefit too!
3) Research. Research a particular area, such as science, history or art.
4) Make a foreign friend. Try to befriend someone from a foreign country. It"s an ideal way to learn about a
foreign country.
5) Publish (出版) an article. Whether it appears in a newspaper, your school magazine or in your own blog,
an article will be something to look back on in pride in later years.
6) Take up a new sport. Choose one you"ve never played before. If you find you like it, you"ll have a hobby
for life.
7) Join a club. Working hard in a club or other activities will give you a life outside of your studies.
8) Find a part-time job. Try and do the job for at least a month.
9) Find a person to learn from. Choose someone with unusual experience or special talent. Try to learn all
you can from him or her.

a team of US scientists discovered an Earth-sized planet called Gliese 581g. It has a surface temperature
neither too hot nor too cold for liquid (液态) water. Scientists think there is a chance that the planet could
have life.
The planet Gliese 581g goes around a star called Gliese 581, which is about 20 light-years from Earth.
That is about 194 trillion (万亿) kilometres-500 million times farther away from us than the moon.
A spacecraft traveling at a one-tenth of the speed of light would reach Gliese 581g within about 220 years.
A human can"t live that long, but robotic explorers could make the job easier. However, our fastest spacecraft
don"t come anywhere near that one-tenth light-speed mark.
At present, scientists don"t know what the surface might be like on Gliese 581g. What they know is that
the planet is at the sight distance from its star to have liquid water. It"s also at the right distance to have an
atmosphere that could protect the water if it is on the surface.
Although spacecraft won"t be getting there anytime soon, one way to look for life on Gliese 581g is to
turn our radio telescopes (望远镜) towards the planet and search for radiation (放射). By studying the
radiation, scientists would find out about the chemicals (化学物质) around the planet and discover it Gliese
581g has an atmosphere. If it has one, studying the atmosphere would give us a good idea if the planet has
life or not. But it"ll probably be many years before we can do this properly.
People have been arguing about whether there is alien life on Gliese 581g. Any discussion about alien life
is just guessing at this point, according to its discoverers.
B. A planet similar to the earth.
C. A planet without life.
D. A planet near the earth.
B. moves around the earth
C. is as far away from us as the moon
D. can be reached in about 220 years
B. the kinds of chemicals around Gliese 581g
C. the way of looking for life on Gliese 581g
D. the aim of studying the radiation on Gliese 581g
B. Gliese 581g, a Likely Living Planet.
C. Gliese 581g and Its Star.
D. Gliese 581g and Radiation.

"USA? Britain? Which country is better to study in?" We often hear such discussions. As China opens its door, it is a dream for many Chinese students to study abroad. They want to learn about the outside world. It"s true that studying abroad can help students develop themselves. Their foreign language skills will be improved and it may be easier to find jobs. But there are problems that should be considered. Language is the first. Students must spend a lot of time learning another language. Students must also learn to live without parents" care and deal with all kinds of things they haven"t had to do before, like looking after themselves. There are reports about Chinese students abroad running into an ocean of difficulties and giving up finally. When they have to take care of themselves, it is hard for students to study well. Finally, studying abroad brings a heavy burden (负担) to the family. For most Chinese parents, the cost of studying abroad is very high. But is it worth it? We know that there are many famous people who have achieved success through their hard work in China. Liu Xiang is a good example. Once an American teacher invited him there, but he refused. He kept training hard with his Chinese teacher. He surprised the world when he won a gold medal at the Athens Olympic Games. So when you wonder which country is better to study in, think again. |
