Space vegetables are grown from seeds (種子) that have been taken to space and brought back to the earth. The seeds are affected by the radiation (輻射) 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 (轉基因) food appeared in the market, people worried that they were eating unknown things. For example, if nut genes (堅果基因) are put inside potatoes, people allergic (過敏的) 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 think of white when someone talks about a polar bear? In fact, the polar bear does not have white fur. It just appears to be white. Polar bears have a very good sense of smell. It helps them to find food. During summer, polar bears sleep longer, because they are able to find their food more easily at night. Usually, after a meal, polar bears have a short sleep. A polar bear can have 2-3 babies at a time. They live with their mothers until they are about two-and-a-half years old.
However, polar bears will die out soon because of people. There are only 20,000 to 25,000 polar bears in the world. The ones that are left are trying to survive today. The number of polar bears is becoming smaller and smaller because of the loss of sea ice— polar bears mostly inhabit (居住于) the sea ice, not the land ice. This is happening because of global warming (全球氣候變暖), pollution, hunting and so on.
Ordinary people don't care, but great people have the power and want to save tigers, fight for giant pandas and save polar bears. Ordinary people will wait, but great people will find a new world.

Though the ways of teaching have come a long way, the ways of communicating between teachers and students are almost the same. But now, a European country is trying to change that by building schools that have no classrooms, no subject lessons and best of all, no grades.
The idea behind the special school is that children are creative. And researchers also think that kids’ learning and ideas are as important as those of the CEO of Google, so why not give them a similar environment? Kids may be successful in such an environment.
To make kids more creative, the schools are built with special learning areas instead of traditional classrooms. And even the lessons are taught in a special way, with mobile phones and computers.
There is no “right” or “wrong” kind of education. The school believes that everything is a learning experience, whether it is about a serious science project or making a movie inside the school’s recording studio.
One of the special schools opened in August, 2011. It has five learning areas. The Cave is a secluded place where students fix their attention on individual (個人的) projects without being bothered (打擾). The Lab is a place where students can do all kinds of experiments and test their ideas. Kids can work in groups in the same projects in The Camp Fire. The Show Off is where kids can show their inventions. And if the kids need a rest, they can visit The Watering Hole, which has all kinds of fun activities.
Sounds great? And the coolest thing is that the school is free! I hope more schools like this will appear in the world!
小題1:What is the idea behind the special school?
A．The children are creative.
B．All the students need to be taught.
C．All the students must be successful.
D．All the students must have high grades.
小題2:From the passage we can infer (推斷) that        in the special schools.
A．students are boredB．students are tired
C．students learn freely D．students learn from their teachers
小題3:“The Cave is a secluded place ….” The word “secluded” probably means “   ” in Chinese.
A．清靜的B．固定的C．吵鬧的D．混合的
小題4:Paragraph 5 mainly tells us that       .              
A．the school doesn’t have grades
