We live in a noisy world. Young and old alike are troubled by sounds over which we may have little or no control: car and house alarms, motorcycles, loudspeakers, even movie previews.
We attend rock concerts, weddings, parties and sports events at which the music is so loud that you can hardly hear the person sitting next to you. At home, televisions, stereos and computer games are often turned up so loud that listeners cannot hear a doorbell or a telephone.
As if environmental noise were not enough, now we surround children with noisy toys and personal listening devices that can permanently damage their hearing. A series of studies conducted in 2002 indicated that even moderate (缓和的) background noise can interfere with how they learn language. In fact, children in classrooms on the noisy side of a school had lower reading scores than those whose classes were on the quiet side.
Noise-induced (噪音诱发的) hearing loss can come about in two ways: from a brief exposure to a very loud noise or from consistent exposure to moderate-level noise. Thus, there is much concern about the lasting effects of MP3 players that are turned up loud enough to block out surrounding sound, like street noise. An MP3 player at maximum volume produces about 105decibels（分贝）— 100 times as severe as 85 decibels, where hearing damage begins.
So, before buying noise-making toys, parents would do well to listen to how loud they are. If the item comes with a volume control, monitor its use to make sure it is kept near the lowest level. Consider returning gifts that make loud noises, or disable the noise-making function. Children who play computer games and stereo equipment should be warned to keep the volume down. Most iPads have a control that allows parents to set a maximum volume.
Avoid taking children to loud action movies. If you do go and the sound seems deafening, ask the management to turn down the volume or insist on your money back.
The League for the Hard of Hearing urges parents to encourage participation in quiet activities, like reading, doing puzzles, making things with construction toys, playing educational computer games, drawing and painting, and visiting libraries and museums.

Many scientists find that colours can change people’s feelings. It’s very interesting. Some colours can make people feel relaxed，and some colours can make people feel nervous. Now，this kind of knowledge is being used in many places. For example，school walls are always painted green because green makes students feel relaxed. It is also good for the students’ eyes. Some books are also green or light blue for the same reason. Restaurant owners not only have to know how to make food，but also have to know how to make money. Here are some things they’ve learned from scientific studies. The colour red makes people hungry. Many fast food restaurants have red furniture or walls. Soft colours like pink and light blue make people feel relaxed，so they spend more time eating. Loud music may be nice at first，but it soon makes people want to leave. Hard seats also make customers want to eat quickly and leave. Many restaurants，especially fast food restaurants，use this knowledge to make customers eat faster.

Do you know why different animals or pests have their special colours? Colours in them seem to be used mainly to protect themselves.
Some birds like eating locusts，but birds cannot easily catch them. Why? It is because locusts change their colours together with the change of the coloursof crops. When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown colour as crops have. Some other pests with different colours from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.
If you study the animal life, you’ll find the main use of colours is protecting themselves. bears, lions and other animals move quietly through forests. They cannot be seen by hunters. This is because they have the colours much like the tree.
Have you ever noticed an even more strange act? A kind of fish in the sea can send out a kind of very black liquid when it faces danger. While the liquid spread over, the enemies cannot find it. And it immediately swims away. So it has lived up to now though it isn’t strong at all.
