In many high schools，there are strict rules about using mobile phones. If your phone rings in class，for example，the teacher will be very angry.

Every mobile phone has a ringtone (铃声). It tells you that someone is calling you. Now，there is a ringtone called “mosquitotone (蚊子铃声)”. Using it，students can receive calls and text messages (短信) in class but the teacher will not realize what is happening. How?

Mosquitotone has a special sound. Only children and teenagers can hear it. As we get older，we are unable to hear some sounds with high frequencies (频率). As a result，a child or teenager can hear the mosquitotone ringtone, but it’s_inaudible_to someone 20 or older.

But sometimes，people over 20 can hear the ringtone. One British student’s phone uses mosquitotone. In class，the student’s phone rang. The 32­year­old teacher looked at the student and became unhappy. “I heard that. You know the rule：no mobile phone in class.”

Not all the students are interested in mosquitotone. Jerry Jones，a high school student of 17，says，“Using mosquitotone too often is bad for our hearing. I may use it for pleasure，but not in class. It’s unfair to the teachers！”

What do parents think of mosquitotone？“I think it is perfect for places like movie theaters，” says Connie Neeson,44.“Think about it. Yon’re watching a film and someone’s mobile phone rings. Mosquitotone is good because many people don’t hear it. However，it also has a bad influence on their study if students use it in class.”

At 9 a.m. on October 15, 2003, our country launched (发射) its first manned (有人的) space-ship, Shenzhou V, into space at Jiuquan Satellite Launch Center in Gansu Province. It took Yang Liwei and his spaceship about 21 hours to circle the earth 14 times. Yang Liwei is China’s first astronaut. He comes from Liaoning Province, and he has been an air force pilot(飞行员) since 1983. He was chosen from 14 pilots after many difficult tests.
The life of an astronaut is hard to imagine for many people. To put on a space suit takes 15 minutes with the help of others. Sleeping in space is not easy, either. He has to sleep in a special sleeping bag on the wall because there is no gravity. Yang can eat chicken and rice. It’s especially made to eat in space but it doesn’t taste nice.
“I’m feeling very good in space, and it looks wonderful here,” said Yang, “I have looked at our beautiful earth and I have recorded all that I have seen here.”
China has become the third country in the world to send a person into space after the former Soviet Union(前苏联) and the United States. China is now planning its next launch. Shenzhou VI will be into space within(在……之内) the next years, it may take three astronauts. We are all proud of our motherland.

One day a man found a cocoon(茧) of a butterfly in the forest. He sat there for several hours and watched the butterfly. Suddenly a small opening appeared, and the butterfly made its great effort to force its body through that little hole. Then it seemed to stop making any progress. It appeared as if it had gotten as far as it could and it could go no further.

So the man decided to help the butterfly. He cut off the remaining bit of the cocoon so that the butterfly could come out easily. But to his surprise, the butterfly got a heavy body and very small wings when it came out of the cocoon.

The man continued to watch the butterfly because he expected that the body would grow smaller at any moment and the wings would become larger and be able to fly. But neither happened! In fact, the butterfly spent the rest of its life crawling (爬) around with a heavy body and small wings. It was never able to fly.

The man was in his kindness, but he did not understand the nature rules. Before the butterfly came out of the cocoon, fluid(流体) from its body must be forced into its wings, and then it would be ready for flying. It must have a hard struggle (拼搏) to get through the small opening to get its freedom from the cocoon.

Sometimes struggles are exactly what we need in our life. If God allowed us to go through our life without any difficulties, it would make us fail. We would not be as strong as we could have been; we could never fly.
