Astronauts' meals have come a long way from the freezedried powders and semiliquid pastes of decades ago:now US scientists want to grow vegetables in minigreenhouses on the moon.
Scientists say they are looking forward to a time when residents of future lunar or even Mar?tian outposts 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.
Paragon,which has partnered with NASA in previous experiments on the Space Shuttle and the International Space Station,calls it a "Lunar Oasis".
This is a sealed greenhouse that looks like a bell jar encased in a 46 cm triangular aluminum frame. 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 $ 20 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 re?search now," Paragon president Jane Poynter said.
"It takes a long time to get a lot of research,and to get integrated,reliable efficient sys?tems before colonists move in ," she said.

For millions of Facebook users,choosing which photo to use for an online profile is an important decision. According to a study by researchers at the UT Dallas Center,the photos we select may reflect individual preferences,but they also appear to reflect more deeply rooted,unconscious cultural differences. Previous research has shown that culture can affect not only language and custom,but also how we experience the world and process information. Western cultures,for example,condition people to think of themselves as highly independent entities (實體) ,whereas East Asian cultures stress collectivism and interdependence.
Dr. Denise Park,codirector of the Center at UT Dallas,and former graduate student Dr. Chih-Mao Huang of the University of Illinois,were curious about whether these patterns of cultural influence extend to cyberspace (網(wǎng)絡(luò)空間) .In a paper published in the International Journal of Psychology,they examined the profile photographs of more than 500 active Facebook users from the United States and East Asia. Overall,they found that profile photos of Americans are more likely to focus on the individual's face,while the profiles of East Asians tend to less emphasize the face and include more background features. Americans also show greater smile intensity compared to East Asian Facebook users.
The findings show marked cultural differences in the focus of attention among East Asian and American Facebook users. Moreover,they echo previous research on cultural influences on visual perception (感知) ,attention,and reasoning in the offline world.
"We believe these findings relate to a cultural bias (偏見,偏差) to be more individualistic and independent in the US and more communal (公共的) and interdependent in Asia," said Park.
The research also found that cultural influences over our selfpresentation online can shift over time and from place to place. In one of the study samples,Americans studying in Japan and Japanese studying in the US both showed a tendency to adjust their profile photos to the general preferences of their host country.
"Facebook constitutes an extended social context in which personal profiles mirror various individual characteristics,private thoughts,and social behaviors," noted Huang. " As such,the study presents a new approach to investigate cognition and behaviors across cultures by using Facebook as a data collection platform."
( ) 1. The underlined word "condition" in the first paragraph probably means .
A. advise B. instruct C. shape D. forbid
( ) 2. We can know from the passage that Mongolians probably emphasize .
A. cultural influences B. social behaviors
C. independent existence D. collective power
( ) 3. It can be inferred that a Korean studying in the US is likely to .
A. use a picture of his face on Facebook
B. adjust to American preferences quickly
C. change his profile photos from time to time
D. put up a photo of his apartment on Facebook
( ) 4. According to Dr. Huang,Facebook can help to .
A. make up a more extended social context
B. study the diversity of worldwide cultures
C. promote communication between east and west
D. combine different cultures from different aspects
