London, Reuters--What could annoy teenagers enough to make them stop hanging out with friends and go home？
No, it's not a visit from their mothers, and not a threat to take away their cellphones or pocket money.
It's high-frequency noise. The UK police recently agreed to use a device (装置) called the Sonic Teenager Deterrent. It sends out a sound that makes teenagers become so impatient and angry that they have to cover their ears tightly and walk away.
The sound is at extreme high-pitch that can be heard by those under 20. The body's natural ability to detect some wave bands decreases almost entirely after 20, so few adults can hear the sounds. The black-box device, nicknamed the Mosquito because of its sound, can be fixed to the outside walls of shops, offices and homes. It sounds to youngsters like a crazy insect or a badly played violin. But it causes no physical damage.
A number of police forces and councils have given permission to use the system and want to install (安装) it at trouble spots.
Staffordshire Police Inspector Amanda Davies, who has given the device to shopkeepers in the Moorlands area, said," It is controlled by the shopkeepers--if they can see through their window that there is a problem, they turn the device on for a while until the group has run away."
【小题1】The device can be used to _______.

George, when your big brother and your little dog and I walked you up to schools today, you had no idea how I was feeling.
You were so excited. You had packed and unpacked your pencils and safety scissors in your backpack a dozen times. I am really going to miss those lazy mornings when we waved your brother and sister off to school.
Because you are my youngest, I had learned a few things by the time you came along. I found out that the seemingly endless days of babyhood are gone like lightning. I blinked(眨眼), and your older siblings were setting off for school as eagerly as you did this morning, I was one of the lucky ones; I could choose whether to work or not. By the time it was your turn, the shining prizes of career advancement and a double income had lost their brightness. A splash(溅水) in the pool with you in your bright red boots or "just one more" rereading of your favorite book, Frog and Toad Are Friends, meant more. You didn’t go to preschool and I hope that doesn’t hold you back. You learned numbers by helping me count the soda cans we returned to the store.
I have to admit that in my mind’s eye, an image of myself while you’re in school has developed, I see myself updating all the photo albums and starting that novel I always wanted to write. As the summer wound down and more frequent quarrels erupted between you and your siblings, I was looking forward to today. And then this morning, I walked you up the steep hill to your classroom. You found the coat hook with your name above it right away, and you gave me one of your characteristically fierce, too-tight hugs. This time you were ready to let go before I was.
Maybe someday you will deliver a kindergartner to the first day of school. When you turn at the door to wave good-bye, he or she will be too deep in conversation with a new friend to notice. Even as you smile, you’ll feel something warm on your cheek.
And then, you’ll know…

“It hurts me more than you”, and “This is for your own good”—these are the statements my mother used to make years ago when I had to learn Latin, clean my room, stay home and do homework.
That was before we entered the permissive period in education in which we decided it was all right not to push our children to achieve their best in school. The schools and the educators made it easy for us. They taught that it was all right to be parents who take a let-alone policy. We stopped making our children do homework. We gave them calculators, turned on the television, left the teaching to the teachers and went on vacation.
Now teachers, faced with children who have been developing at their own pace for the past 15 years, are realizing we’ve made a terrible mistake. One such teacher is Sharon Klompus who says of her students “so passive” and wonders what has happened. Nothing is demanded of them, she believes. Television, says Klompus, contributes to children’s passivity. “We’re talking about a generation of kids who’ve never been hurt or hungry. They have learned somebody will always do it for them, instead of saying ‘go and look it up’, you tell them the answer. It takes greater energy to say no to a kid.”
Yes, it does. It takes energy and it takes work. It’s time for parents to end their vacation and come back to work. It’s time to take the car away, to turn the TV off, to tell them it hurts you more than them but it’s for their own good. It’s time to start telling them no again.
