If you are writing or studying, it makes very much difference where the light comes from. People who use books and pens every day have to be especially careful about the way the light shines on their work.

Every house gets its light either from daylight through the windows--which is the best to use--or from lamps or electricity; but whichever kind of light it is, the way it shines toward our book or work is a matter of great importance to the eyes.

Take a book, sit with your back toward the window, and try to read. Your shadow(影子) falls all over the page and makes it almost as bad for your eyes as if you were in a dark room. Now turn around and face the window. The page is in the shadow again, while the bright light is in your eyes.

Try sitting with your right side toward the window. This is very well for reading, but if you were writing, the shadow of your hand would fall across the page and bother(打搅) you a little.

There is just one other way:sit with your left side to the window. Now everything is perfect for reading and for writing, too.

Whatever kind of light is in the room, the rule about the right to sit is always the same.

Cats are creatures of habit.They like to go to sleep about the same time every day and for a certain length of time.They seem to have a natural clock inside them that tells them when to sleep.

Cats increase their regular sleep with occasional cat naps（打盹）.Some experts feel that humans could also benefit from this habit.Cat naps help to build up energy in the body.They are also a good way to get rid of trouble!Since cats have the same moods（情绪）as humans,some experts behave that people can improve their moods.People might become happier.

A number of famous people have copied cats by taking cat naps during the day.The naps would usually last from 15 to 30 minutes.

Winston Churchill took cat naps.So did Presidents Harry Truman,John F.Kennedy and Lyndon B.Johnson.These famous men were known for their energy.They were also able to work long hours,often into the night.Napping was their secret.

Perhaps more people learn from cats and take naps to feel better and live longer!

When did you last see a polar bear?On a trip to a zoo,perhaps?If you had attended a winter activity in New York a few years ago,you would have seen a whole polar bear club.These"Polar Bears"are people who-meet frequently in winter to swim in freezing cold water.That day,the air temperature was 3oC,and the water temperature was a bit higher.The members of the Polar Bear Club at Coney Island,New York are usually about the age of 60.Members must satisfy two requirements.First,they must get along well with everyone else in the group.This is very important because there are so many different kinds of people in the club.Polar Bears must also agree to swim outdoors at least twice a month from November through February.

Doctors do not agree about the medical effects of cold-water swimming.Some are worried about the dangers of a condition in which the body′s temperature drops so low that finally the heart stops.Other doctors,however,point out that there is more danger of a heart attack during summer swimming because the difference between the air temperature and water temperature is much greater in summer than in winter.

The Polar Bears themselves are satisfied with the benefits（or advantages）of cold-water swimming.They say that their favorite form of exercise is very good for the circulatory system（循环系统）because it forces the blood to move fast to keep the body warm.Cold-water swimmers usually turn bright red after a few minutes in the water.A person who turns blue probably has a very poor circulatory system and should not try cold-water swimming.

The main benefits（or advantages）of cold-water swimming are probably mental.The Polar Bears love to swim year-round;they find it fun and relaxing.As one 70-year-old woman says,"When I go into the water,I pour my troubles into the ocean and let them float away."

The Polar Bears like to swim all the year round,for

When did you last see a polar bear?On a trip to a zoo,perhaps?If you had attended a winter activity in New York a few years ago,you would have seen a whole polar bear club.These"Polar Bears"are people who-meet frequently in winter to swim in freezing cold water.That day,the air temperature was 3oC,and the water temperature was a bit higher.The members of the Polar Bear Club at Coney Island,New York are usually about the age of 60.Members must satisfy two requirements.First,they must get along well with everyone else in the group.This is very important because there are so many different kinds of people in the club.Polar Bears must also agree to swim outdoors at least twice a month from November through February.

Doctors do not agree about the medical effects of cold-water swimming.Some are worried about the dangers of a condition in which the body′s temperature drops so low that finally the heart stops.Other doctors,however,point out that there is more danger of a heart attack during summer swimming because the difference between the air temperature and water temperature is much greater in summer than in winter.

The Polar Bears themselves are satisfied with the benefits（or advantages）of cold-water swimming.They say that their favorite form of exercise is very good for the circulatory system（循环系统）because it forces the blood to move fast to keep the body warm.Cold-water swimmers usually turn bright red after a few minutes in the water.A person who turns blue probably has a very poor circulatory system and should not try cold-water swimming.

The passage is mainly about

Life gets noisier every day and very few people can free from noise of some sort or another.It doesn′t matter where you live--in the middle of a modem city,or a faraway village--the chances that you will be disturbed by jet aero 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.
