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 to nuts might get sick from eating these potatoes because they do not know they are also eating nuts.

I've been working as a professional clown(小丑)for nearly two years. Before that, I was an actor for nine years. I was never famous, but I was quite successful! I changed jobs because I wanted to do more in life than make people laugh. What if I could help people, too?
As a clown, I try to encourage sick children in hospital to laugh and smile. When you laugh, your mind and body relax. Clearly, people who laugh more don't have as many colds or other problems! Children who laugh a lot often get better results in their studies, too.
It isn't an easy job. Not all sick children get better, and sometimes I come home and cry. But I always go back to work the next day with my red nose on. l don't earn much money as a clown, but I feel very lucky to work with such brave and wonderful patients.
I became a laughter yoga(瑜伽)teacher more than two years ago. Before that, I was a dentist! My job was very difficult, and I used to feel fed up. Now I still improve people's health, but everything else is completely different. Everyone has fun in a laughter yoga class, including the teacher!
No, laughter isn't "magic". It doesn't prevent all illness, keep you young, or make you beautiful. But did you know that it's an excellent kind of exercise? You move your whole body when you laugh!
Sometimes I work with famous people. It's true that being rich can be stressful! Some famous people can be unpleasant at times, but I try to change their bad feelings. Laughter is excellent for people like musicians, artists and writers, because it helps people to be more creative.
