It’s the lunchtime break at Shanghai Xianxia Middle School. No mobile phones can be heard ringing anywhere. The common sight of crowds of children chatting on their phones or sending short messages has disappeared(消失).

A grade-2 student said: “I couldn’t concentrate(集中精力) during classes if the phone was with me. I couldn’t help checking if there were messages or missed phone calls. I even played games on the phone sometimes.”

The school leaders say they feel the ban(禁令) is necessary to keep order in class. They even gave out an open letter to remind parents not to let their children bring mobile phones to school. More than 96 percent of parents say they welcome the school decision. The school is also being flexible(灵活的)in implementing the ban. Those students who live far from school are allowed to bring mobile phones to call their parents. But they still have to turn them off in classrooms.

Medical experts(专家) have also welcomed the school decision. They say too much dependence on mobile phones can cause many psychological problems in school students.

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.
