change. They could see the moon was made of rocks. Most scientists thought moon rocks would be different from those on the earth. This was because they believed the moon had once been a planet that had been caught in the earth’s gravity millions of years earlier.
In 1969, moon rocks were finally brought to the earth and studied. Much to their surprise, scientists found that, except for water, the moon and the earth were made of the same things. Once again new ideas were needed for this new information.
After years of study, most scientists now think that the moon was once part of the earth. They believe very early in its history, maybe 4 billion years ago, something about the size of Mars hit the earth. This sent billions of rocks into space around our planet. These rocks slowly joined together and after many years became the moon.
In the future, even though our ideas about the moon may change again, we will still be interested in it.

On June 24, 1947, a US pilot named Kenneth Arnold looked out the window of his plane and saw nine silver objects flying close together.
They were moving very quickly. Kenneth guessed that their speed was more than 1,600 kilometres an hour. He told journalists that the objects did not move like planes, but like saucers move when someone throws them across the surface of water. Later one of the journalists called the objects “flying saucers”.
This was the first time the expression “flying saucer” was used, but people have seen UFOs (unidentified flying objects) in the sky centuries ago. For example, in the thirteenth century some English farmers saw a flat, silver object in the sky. This is surprising because in those days there were no planes, weather balloons, or space stations that could be mistaken for UFOs.
Today, many UFOs turn out to be something quite ordinary. One evening in February 2001, eight colored lights appeared in the sky above Kuala Lumpur in Malaysia. The lights seemed to float in the air for ten minutes before moving off and disappearing. Many people thought they were UFOs. They turned out to be good luck lanterns that had been released from a temple.
Most UFOs can be explained like this. However, there are many that can’t. Surveys show that at least half of us believe intelligent life exists on other planets. Is it possible, therefore, that someone from “out there” is visiting us? 根据短文内容，回答下列问题。
36.Where was Kenneth Arnold when he saw the silver objects? ________________________________________________ 37.How many silver objects were there in the sky?
