When we accept the evidence of our unaided eyes and describe the Sun as a yellow star, we have summed up the most important single fact about it—at this moment in time. It appears probable, however, that sunlight will be the color we know for only a small part of the Sun’s history.
Stars, like individuals, age and change. As we look out into space. We see around us stars at all stages of evolution. There are faint bloodred dwarfs school that their surface temperature is a mere 4,000 degrees Fahrenheit, there are searing ghosts blazing at 100,000 degrees Fahrenheit and almost too hot to be seen, for the great part of their radiation is in the invisible ultraviolet range. Obviously, the "daylight" produced by any star depends on its temperature; today (and for ages to come) our Sun is at about 10,000 degrees Fahrenheit, and this means that most of the Sun’s light is concentrated in the yellow band of the spectrum, falling slowly in
A. The dangers of invisible radiation.
B. Faint dwarf stars.

A university professor recently made several tests with different animals to find out which was the most clever. He found out that the monkey was cleverer than the other animals he studied.
In one test the professor put a monkey in a room where there were several small boxes. Some boxes were inside other boxes. Inside one small box was some food. The professor wanted to watch the monkey and find out how long it would take the monkey to find the food. The professor left the room. He waited a few minutes outside the door. Then he got down on his knees and put his eye to the keyhole. What did he see To his surprise, he found himself looking into the eye of the monkey. The monkey was on the other side of the door looking at the professor through the keyhole, checking to see if the professor had really left!

When we can see well．we do not think about our eyes very often．It is(11) only when we cannot seeperfectly that we come to see how important our eyes are.People who are nearsighted can only see things that(12) are very close to their eyes. Many people who doa lot of close work，(13) such as writing, reading and sewing,become nearsighted.They have to wear glasses(14) in order to see distant things clearly. (15) Peoplewho are farsighted suffer from just the oppsite problem,They can see things that are far away，but theyhave difficulty reading a book unless they hold it atarm’s length．If they want to do much reading，theymust get glasses，too．
