Space vegetables are grown from seeds (种子) that have been taken to space and brought back to the earth. The seeds are affected by the radiation (辐射) and low gravity in space. When they are brought back to the earth, these seeds produce vegetables that are bigger and healthier than normal vegetables. However, some people worry about eating space vegetables. They think that space vegetables might not be good for us and could make us get sick because of the radiation in space. However, people should not be frightened because space vegetables are very healthy.
Here are some facts that you should know about space vegetables.
Space vegetables are grown from seeds that are carefully chosen. When seeds are brought back from space, they are tested to make sure that they will be safe to eat.
Space vegetables are better for you than normal vegetables. For example, space tomatoes stay fresh for twenty days, which is one week longer than normal tomatoes.
After genetically modified (转基因) food appeared in the market, people worried that they were eating unknown things. For example, if nut genes (坚果基因) are put inside potatoes, people allergic (过敏的) to nuts might get sick from eating these potatoes because they do not know they are also eating nuts. Unlike genetically modified food, space vegetables have not been genetically changed. This means that no new genes are put into the vegetables. Therefore, there are no dangers of eating something unknown.

Do you have a vegetable garden? Have you ever watched a seed (种子) sprout (发芽), grow and fruit until it became the tomato on your plate? If you go to school in the US, there’s a good chance you have.
At the moment, nearly 20 percent of schools in the US have their own vegetable gardens that are planted and cared for by students. Next year, even more schools will have gardens and more US kids will know the pleasure of growing their own food.
Much of the growing interest in planting comes from First Lady Michelle Obama’s “Let’s Move” project, which started last year. The First Lady wants to improve children’s nutrition (营养) in the US — and she began her project by planting a garden at the White House with the help of some local kids. The kids were more interested in eating the vegetables from their garden than in eating fast food. This gave the First Lady an idea.
Because so many US kids eat breakfast and lunch at school, the food should be healthy and good. Why not let kids grow the food for their own cafeterias (食堂)? Mrs .Obama’s plan gives money to schools to start their own gardens, and more school gardens are sprouting up every day.
Students also use the information from their gardens to study science and math, and they paint pictures of their gardens in art class. Many students choose to work in the garden instead of playing on the playground during their noon break. Sound like fun? Ask your teacher if there’s room for a garden at your school, too.

A computer program that could help catch and ever translates from aliens in outer space has been started by a British scientist.
If aliens are discovered one day, scientists fear their language may make it possible to understand them. But John Elliott of needs Metropolitan University in Britain has come up with a program that can figure out the structure(结构)of their language. He thinks that’s the first step in understanding what they are saying.
Dr.Elliott’s program would compare an alien language to a database(数据库)of 60 different languages in the world to look for a similar structure. He believes that even an alien language will have its own structure.Language has to be structured in a certain way, or it will be harder to use,he told New Scientist magazine.
Research had shown that it is possible to know if a signal(信号)carries a language rather than a picture or music. Dr.Elliott has gone a step further by finding a way to pick out what might be words and sentences. Because languages have different word orders, Dr.Elliott has set up a library of the sentence structures of 60 human languages.
If a message is received from outer space, it could be compared against this database. Scientist would then be able to see if ti’s similar to any human language, or a mix of the language.
However, Dr.Elliott also said that in order to translate what the aliens are actually saying, it may still be necessary to have a code book.
1.Why did Dr.Elliott come up with the program?
A. To learn more about outer space. B. To develop a new language.
C. To help translate the messages for aliens. D. To compare an alien language to human languages.
2.According to Dr.Elliott, what’s the first step of understanding an alien language?
A. Coming up with a program. B. Knowing a structure.
C. Understanding aliens. D. Discovering aliens.
3.What does paragraph 4 mainly tell us?
A. Some necessary conditions for making the program work.
B. Dr.Elliott’s findings about different kinds of languages.
C. Three important functions of the program.
D. The number of sentence structures of human languages.
4.How does the program work when it receives a message from aliens?
A. Mix the message with 60 human languages.
B. Translate the message and send it to the database.
C. Pick out the sentence structure and translate it.
D. Compare the message to the database of 60 human languages.
5.What can we infer from the story?
A. Not all languages have their own structure.
B. The structure of alien languages is similar to that of human languages.
C. To translate alien languages, there is much work to do..
D. Alien languages are signals carrying pictures and music.
