From boyhood he had been interested in astronomy(天文学), and while at Cambridge he would sit up at night to watch the stars. But he was not satisfied with the telescopes of those days because they didn't show him a clear picture of things. At first he thought there must be something wrong with the lens. But no matter how hard he tried to improve the lens; the trouble was still there.
This set Newton thinking. He began to study the nature of light and colors. In the end he found that sunlight, or white light, is actually made up of a row of colors. He counted seven colors in all. This was of course a great discovery. But Newton still wasn't satisfied His mind was busy with another problem. Before Newton's time, scientists had already discovered that the sun, not the earth, was the centre of the other planets moving round the sun. But they couldn't explain why this was so until Newton gave the answer.
One autumn evening while Newton was sitting under an apple tree thinking over these problems, he saw the moon rise in the sky. Why, he asked himself, should the moon go round the earth, never leaving the same path? At that moment, he heard an apple drop from the tree. Why didn't it go sideways or fly up?
There seemed to be only one reason：the earth was drawing it－that is the force of gravity. If a stone is tied to the end of a string and whirled around, it will fly round and round in circles because of the string. In the same way, the force of gravity, thought Newton, must be the force that keeps the moon going round the earth and the planets round the sun.

[ ]
A．Newton gave the right answer to the making up of the sunlight

3．Give the right order of the events given in the passage.
a．Newton found that the sunlight is made up of a row of colors.
b．Newton wondered why the apples didn't go sideways.
c．Newton concluded that the force of gravity keeps the moon going round the earth.
d．Newton tried every means to improve the lens.
e．Newton counted the number of colors.

Much of the water we use comes from snow. Melting snow provides water for rivers, electric power centers and agricultural crops. In the western United States, mountain snow provides up to 75% of all surface water supplies.
Snowfall helps to protect plants and some wild animals from cold, winter weather. Fresh snow is made largely of air trapped among the snow crystals. Because the air has trouble moving, the movement of heat is greatly reduced.
Snow also is known to influence the movement of sound waves. When there is fresh snow on the ground, the surface of the snow takes in, or absorbs, sound waves. However, snow can become hard and flat as it becomes older or if there have been strong winds. Then the snow's surface will help to send back sound waves. Under these conditions, sounds may seem clearer and travel farther.
Generally, the color of snow and ice appears white. This is because the light we see from the sun is white. Most natural materials take in some sunlight. This gives them their color. However, when light travels from air to snow, some light is sent back, or reflected. Snow crystals have many surfaces to reflect sunlight. Yet the snow does take in a little sunlight. It is this light that gives snow its white appearance.
Sometimes, snow or ice may appear to be blue. The blue light is the product of a long travel path through the snow or ice. In simple terms, think of snow or ice as a filter. A filter is designed to reject some substances, while permitting others to pass through. In the case of snow, all the light makes it through if the snow is only a centimeter thick. If it is a meter or more thick, however, blue light often can be seen.
1.How many functions of snow are discussed in the passage?
A．One B．Two C．Three D．Four
2.Why does snowfall help to protect plants from cold?
A．Because snow crystals contain heat.
B．Because snow crystals have air in them.
C．Because snow crystals are easy to blow away.
D．Because snow crystals send out heat when melting.
3.It can be inferred that ______.
A．hard snow is better in protecting wild animals than fresh snow
B．fresh snow is better in sending sound waves than hard snow
C．fresh snow is better in taking in sound waves than hard snow
D．hard snow provides less water than fresh snow
4.The color of snow and ice appears white because snow crystals________.
A．send back none of the sunlight B．send back all of the sunlight
C．take in most of the sunlight D．take in some of the sunlight
