Did you visit the Shanghai World Expo last summer? What impressed (给……留下印象)  you? 21st Century Kids invites four kids to talk about their experiences. They are back from the Expo. What did they bring us? Let’s see what they have to say.

I went to the SAIC-GM Pavilion (上汽集团通用汽车馆). I found my dream car there. It is a green car. Its name is “Leaf”. Chinese engineers made the car. Its roof is in the shape of a leaf. The roof takes in CO2 and changes it into electricity for the car.

The Japan Pavilion is full of high technology. The “Wonder Camera” is cool. It can find a smiling face in a crowd. When you’re smiling, it takes a photo of you. I want to invent something like that in the future.

My favorite pavilion is the Germany Pavilion. I watched the Energy Source show. Visitors made a ball swing back and forth (来回摇摆) by using only their voices. It’s amazing! Although we had waited for quite a long time before we entered the hall, I think it is well worth seeing with your own eyes.

I like painting, so my parents took me to the France Pavilion to see the famous paintings. But the French cooks caught my eye. I saw them cook. My mom told me that they are some of the best cooks in the world. The dish they cooked looked like a painting. So, being a cook is my second dream job.

1.The 21st Century Kids seems to be _____.

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.”
【小题1】Mosquitotone works because ________.
A.it is very loudB.it has no sound
C.it has a beautiful soundD.it uses high frequencies
【小题2】The under lined part “it’s_inaudible_to” means “________”.
A.it can’t be seen byB.it can’t be heard by
C.it isn’t popular withD.it isn’t healthy for
【小题3】The 32­year­old teacher felt unhappy because the student ________.
A.was late for classB.didn’t do his homework
C.couldn’t answer her questionD.was using a mobile phone in class
【小题4】Connie Neeson thinks that mosquitotone ________.
A.has no bad influenceB.is unfair to the teachers
C.has its advantage and disadvantageD.can’t be used in any public place
