Astronauts’ meals have come a long way from the free-dried powders and semi—liquid pastes of decades ago，now US scientists want to grow vegetables in mini—greenhouses on the moon．
Scientists say they are looking forward to a time when residents of future lunar or even Martian outsteps will be able to dine on fresh vegetables．Paragon Space Development Corporation has unveiled what it called the first step toward growing flowers——and eventually food on the moon．
This is a sealed greenhouse that looks like a bell jar encased in a 46-cm triangular aluminiumframe．It is designed to safely land a laboratory plant on the lunar surface，and protect it while it grows．
The miniature greenhouse is to be launched into space by Odyssey Moon Ltd, a participant in the Google Lunar X Prize. This competition offers $21 million to any entrant who can launch, land and operate a rover on the lunar surface.
Paragon officials say future testing of the “Lunar Oasis” will be driven by Odyssey’s flight Schedule, which will not happen until 2012 at the earliest．
When it does lift off the greenhouse will contain the seeds of Brassica, a hardy plant related to Brussels sprouts and cabbage. Because Brassica goes from seed to flower in just 14 days, it can complete its life cycle in a single lunar night.
“Colonizing the Moon or Mars seems so far away，but it is important that we do this research now. ”Paragon president Jane Poynter said．
“It takes a long time to get a lot of research, and to get integrated, reliable efficient systems before colonists move in. ”she said．
1.The article is written mainly to__________．
A. predict the astronauts’ meals in the future
B. introduce an experiment “Lunar Oasis’’
C. tell us the future development of astronomy
D. focus on the human’s great progress
2.The article implies that__________．
A. astronauts can grow flowers in space at present
B. Paragon and NASA will carry out the test separately
C. Lunar Oasis is a series of experiments carried out in space
D. the earliest testing of the Lunar Oasis may be in 2012
3.The underlined word “colonists” in the last paragraph probably has the meaning of______．
A. plants B. wild beasts C. human beings D. scientists
4.The seeds of Brassica will be contained in the greenhouse mainly because _________.
A. their life cycle is much shorter
B. they are more nutritious than other food
C. they are related to Brussels sprouts and cabbage
D. they are very delicious

Human civilization has truly come a long way．From using animals for transport to the super fast automobiles that we have today．From using flint to making fire to using one touch lighters．But there are some things that we will never let go of．Some ancient traditions that have been brought down through the ages are still followed today．
Groundhog Day(土拔鼠节)，falls on the 2nd of February every year．It is observed in the United States and Canada．While this day may be a public holiday and a bank holiday，it is not a compulsory holiday declared by the government．But this is not so for all the states．State-wise holidays may vary．
Ever heard of Punxsutawney Phil? Groundhog Day is observed because of this groundhog．The day is indeed about a groundhog．Punxsutawney is the name of an apparently weather forecasting groundhog．He lives in his burrow(洞穴)on Gobler’s Knob，Punxsutawney in Pennsylvania，for a short period before the 2nd of February every year．On the 2nd of February，Phil comes out from his burrow and looks for his shadow．If he sees his shadow and goes back into the burrow，then America will have an extended winter of six weeks，But if he cannot see his shadow，and he remains outside．It means winter will soon end and spring will arrive very shortly .Phil has been‘predicting’the length of winter in this manner for almost a century and they have always been almost 100％ accurate．
Groundhog Day is celebrated in some parts of the USA and Canada．The largest celebration is held at Punxsutawney，Pennsylvania．People come in scores to visit Punxsutawney Phil．They wait eagerly, camping days in advance，to see the small groundhog appear from his burrow，check for his shadow and either go back in or stay out．People cheer when they hear it is time for winter to end and celebrate by eating sweets and singing and dancing．Today．the Groundhog Day is a widespread tradition and an exciting event．

Christa McAuliffe was born in 1948 and she was an astronaut almost by accident. In 1984, NASA decided to find a teacher who could accompany astronauts into space. They hoped that she would be able to communicate with students from space and encourage every one of them to be interested in space travel. Christa was a secondary teacher in history and social studies. She was a gifted teacher and she was selected from over 11,000 applicants to go on flight STS-51-L. She was also a very good communicator and she immediately established a very good relationship with the news media(radio, television and newspapers）. It was partly because of this that there was a great deal of interest and excitement about the flight. Thousands of students in schools and universities all around the country were looking forward to communicating with Christa in space. Millions of people were watching her flight with great interest. It is partly because of the excitement over McAuliffe's place in the flight that the disaster in 1986 had such an effect on people.

Researchers from the University of Michigan have found that astronauts’ brains change shape during spaceflight. It is the first study1.(look) into how the brain changes in space. Researchers looked at high-tech MRI(磁共振成像)pictures of the brains of 26 astronauts who spent time in space. Twelve of the2.(astronaut) spent two weeks on the Space Shuttle, and 14 spent six months on the International Space Station. All of them3.(experience) increases and decreases in the size of 4.(differ) parts of the brain. The longer an astronaut spent in space ,the 5.(big) the size differences were.
The research produced some6.(interest) findings. One was that on gravity means fluids do not drop in the body, 7.there is a shift in the brain’s position inside the skull. The brain becomes either smaller or bigger. The findings could help doctors to treat problems that affect the brain’s function. They could treat people with problems 8.(cause)by long-term bed rest. They could also help those who have a build-up of fluid in the brain, which can lead9.brain damage. We will understand more about 10.neurons(神经元)in the brain connect. The findings will also help future trips to Mars.

Scientists who discovered a new way of generating electricity from water say they may have come across an alternative source of clean energy to rival wind and solar power.
The breakthrough, which scientists say is the first new way to generate electricity in 160 years, could lead to batteries that use water instead of poisonous substances.
The scientists made the discovery when they were investigating what happens when tap water is forced through extremely narrow glass tubes. Water squeezed down the tubes, each of which was narrower than a tenth the thickness of a human hair, generating a small electric current that ran the length of the tube. To produce a larger electric current, the team tried forcing water through a glass water filter(滤水器)that contained thousands of narrow channels lined up side by side. “When we took a syringe(注射器)of water and squeezed it through the filter, we got enough power to light a light bulb,” said Larry Kostiuk of the University of Alberta in Canada. “The harder you push the syringe, the more electric current you get.”
The current is produced because of an effect in the glass tubes. When they are filled with water, positively charged ions(阳离子)fixed in the tubes are washed away, leaving a slight negative charge on the glass surface. When water is then forced along the tube, the surface repels negatively charged ions in the water while positively charged ions are attracted down the tube. The result is a net flow of positively charged ions that sets up an electric current.
According to Dr Kostiuk, no one has ever thought to use water to produce electricity in this way. “The last time someone came up with a way of generating electricity was Michael Faraday in 1839,” he said. “So this is the first new way of generating electricity in 160 years, which is why we are so excited about it.”
Dr Kostiuk says water batteries might one day be used to power mobile phones and calculators, but admitted that the engineering challenges might make other applications more realistic. “You’d need to be sure it wouldn’t leak, and you’d need to make sure it wouldn’t freeze,” he said.
More likely would be to install the electricity-generating devices where water is already being pumped, such as at city water filtration sites, he said. “It could compete with wind and solar power,” he added.
1.What does the passage mainly want to tell us about?
A. A kind of solar power discovered by scientists.
B. A kind of new energy source found in tap water.
C. The breakthrough to generate electricity 160 yeas ago.
D. A kind of new battery invented without poisonous substances.
2.The underlined word “repels” in Paragraph 4 is closest in meaning to _________.
A. rejects B. identifies C. attracts D. rebels
3.Why were the scientists extremely happy about their new discovery?
A. They were the first to find a new way to produce electricity.
B. They could make an electric current to light a light bulb.
C. Their discovery could be used to invent water batteries.
D. Their discovery was made 160 years earlier than Faraday’s.
4.What can we infer about potential water batteries?
A. They must be used to power mobile phones and calculators.
B. They have some possible disadvantages like water leaking.
C. They would be needed greatly at city water filtration sites.
D. They would be better than wind and solar power.
