Life gets noisier every day and very few people can be free from noise of some sort or another. It doesn’t matter where you live－ in the middle of a modern city, or a faraway village the chances that you will be disturbed by jet planes , transistor radios, oil-powered engines, etc, are almost everywhere. We seem to be getting used to noise, too. Some people feel quite lonely without background music while they are working.
Scientific tests have shown that total silence can be very frightening experience for human beings. However, some people enjoy listening to pop music which is very loud, and this can do harm to their eardrums (耳鼓). The noise level in some disco is far above the usual safety level for heavy industrial areas.
One recent report about noise and concentration(专心) suggested that although a lot of people say that any noise disturbs their concentration , what really affects their ability to concentrate is a change in the level of noise. It goes on to say that a background noise, which doesn’t change too much (music, for example ) may even help people to concentrate.

Are your children liked by their teachers? All parents want their children to impress(给...的印象) their teachers and succeed in school. You can get your children to impress their teachers by following these easy steps.
Make sure they’re prepared. Teachers are impressed by children coming to school prepared to learn. Make sure they have everything they need—pencils textbooks, erasers and so on.
Require them to be active in class. Teach them to ask teachers questions when they don’t understand something. Some children think teachers are bothered by questions, but most teachers are impressed when children take the initiative(采取主动) in asking questions. They should take part in class discussions, giving their opinions politely.
Keep your children healthy. If your children are tired and hungry, they won’t be ready to learn. Children need at least 8 to 10 hours of sleep per night. Feed your children a solid breakfast and prepare a healthy lunch. Provide them with fruit and other healthy foods—apples or bananas are better for them than cookies.
Make sure that your children do their homework. If they really don’t understand it, discuss it with them patiently. Don’t help them do their homework. Teachers can always tell who it is that does the work.
Teach your children good manners and habits. Children need to arrive at the school punctually, and be polite to their teachers and classmates. Parents need to teach these skills at home. Nothing is sweeter than children who say “please” and “thank you”, and these are children their teachers are certain to love.

A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below 16℃.Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate. Without the forest cover, these areas would reflect more heat into the atmosphere，warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns, potentially causing certain natural disasters all over the world.
In the past hundred years, humans have begun destroying rainforests in search of three major resources (资源): land for crops, wood for paper and other products, land for raising farm animals. This action affects the environment as a whole. For example，a lot of carbon dioxide(二氧化碳)in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit.
There are two main reasons for this. Firstly, when people cut down trees, generally they can only use the land for a year or two. Secondly, cutting large sections of rainforests may provide a good supply of wood right now, but in the long run it actually reduces the world’ s wood supply.
Rainforests are often called the world’s drug store. More than 25% of the medicines we use today come from plants in rainforests. However, fewer than 1% of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking rainforests.
