Earplugs have been the simple but effective way to stop noise affecting your mind, but their shortcoming is that they also block out sounds you may want or need to hear, such as music or someone talking to you.
The answer to this problem is "active noise cancellation(抵消)"-headphones that are made up of a microphone and electronics(电子装置) that take all background low-frequency (低频率) noise, turn the sound waves upside down and rebroadcast them into your ear.
The result is that all the unwanted noises around are blocked out.
In effect, one set of electronically produced sound wave has sucked away the unwanted sound waves of noise.
Stand next to a busy road wearing the noise cancellation headphones and the traffic noise disappears. Sit in an airplane and the engine noise dies away. In a noisy office, the noise of office equipment, people and air-conditioning is gone. You can still, however, hear music or talk with people because that sound does not have a regular pattern and so the device(装置) does not block it.
81. What is the best way to keep out the unwanted noise?
A. To wear an earplug.
B. To wear a headphone.
C. To wear a microphone.
D. To wear electronics.
82. Which of the following gives a general idea on how the above device works?
A. By producing low-frequency sound waves and rebroadcast them.
B. By producing new sound waves to suck away the unwanted sound waves.
C. By changing all background low-frequency noise into an irregular pattern.
D. By sucking away all the low- frequency sound waves turned upside down.
83. Suppose you are driving your friend to the airport and the car radio is on, what can't you hear if you wear a headphone?
A. The radio music and the car engine noise.
B. The noise of the planes passing overhead and what your friend says.
C. The radio music and what your friend says.
D. The noise of the car and the planes passing overhead.

Kids will often ignore your requests for them to shut off the TV,start their chores(杂事),or do their homework as a way to avoid following your directions.Before you know it,you’ve started to sound like a broken record as you repeatedly ask them to do their assignments,clean their room,or take out the trash.Rather than saying “Do your chores now.” you’ll be more effective if you set a target time for when the chores have to be completed.So instead of arguing about starting chores,just say,“If chores aren’t done by 4 pm,here are the consequences.”Then it’s up to your child to complete the chores.Put the ball back in their court.Don’t argue or fight with them,just say,“That’s the way it’s going to be.”It shouldn’t be punitive(惩罚性的)as much as it should be persuasive.“If your chores aren’t done by 4 pm,then no video game time until chores are done.And if finishing those chores runs into homework time,that’s going to be your loss.”On the other hand,when dealing with homework,keep it very simple.Have a time when homework starts,and at that time,all electronics go off and do not go back on until you see that their homework is done.If your kids say they have no homework,then they should use that time to study or read.Either way,there should be a time set aside when the electronics are off.
When a kid wears his iPod or headphones when you’re trying to talk to him,make no bones about it；he is not ignoring you,he is disrespecting you.At that point,everything else should stop until he takes the earplugs out of his ears.Don’t try to communicate with him when he’s wearing headphones — even if he tells you he can hear you.Wearing them while you’re talking to him is a sign of disrespect.Parents should be very tough about this kind of thing.Remember,mutual respect becomes more important as children mature.

Kids will often ignore your requests for them to shut off the TV, start their chores (杂事), or do their homework as a way to avoid following your directions. Before you know it, you’ve started to sound like a broken record as you repeatedly ask them to do their assignments, clean their room, or take out the trash. Rather than saying, “Do your chores now”, you’ll be more effective if you set a target time for when the chores have to be completed. So instead of arguing about starting chores，just say, “If chores are’t done by 4 p.m, here are the consequences.” Then it’s up to your child to complete the chores. Put the ball back in their court. Don’t argue or fight with them，just say, “That’s the way it’s going to be.” It shouldn’t be punitive (惩罚性的) as much as it should be persuasive. “If your chores aren’t done by 4 p.m, then no video game time until chores are done. And if finishing those chores runs into homework time, that’s going to be your loss.” On the other hand, when dealing with homework, keep it very simple. Have a time when homework starts, and at that time, all electronics go off and do not go back on until you see that their homework is done. If your child says they have no homework, then they should use that time to study or read. Either way, there should be a time set aside when the electronics are off.
When a kid wears his iPod or headphones when you’re trying to talk to him, make no bones about it; he is not ignoring you, he is disrespecting you. At that point, everything else should stop until he takes the earplugs out of his ears. Don’t try to communicate with him when he’s wearing headphones—even if he tells you he can hear you. Wearing them while you’re talking to him is a sign of disrespect. Parents should be very tough about this kind of thing. Remember, mutual(相互的) respect becomes more important as children mature(成熟).
