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.”

It was the last day of final exams in a university. On the steps of one building, a group of engineering students were discussing the exam. On their faces was confidence . This was their last exam and then they would graduate. With all these four years of college behind them, they felt ready to go into the world.
The professor had said they could bring any book or note they wanted, but they could not talk to each other. They went into the classroom happily. The professor gave them the papers. They smiled when they found that there were only five questions.
Three hours passed and the professor began to collect the papers. The students no longer looked so confident . The professor faced the class. No one spoke. They just held papers in their hands.
The professor then asked, "How many of you finished all five questions?"
Not a hand was raised.
"How many answered four?"
Still no hand.
"Three? Two?"
The students looked worried in their seats.
"One, then?" Certainly somebody finished one.
However, nobody replied. The professor put down the papers. "That is just what I thought," he said. "I just want to tell you that, even though you have finished four years of engineering, there are still many things about the subject you don't know. These questions you could not answer are quite common in everyday practice." Then he added with a smile, “You will all pass this course, but remember——even though you are now college graduates, your education has just begun."

  Field Trip Day

On Friday, May 6, our class will take a field trip to North Park Zoo.  The zoo has lions, elephants, and other interesting animals.  Many of the animals we have been studying will be there for us to closely examine.                         

                            Our class will be divided into six teams.  Each team will have five students and one leader.  The leaders are listed in the table.
