We have always been interested in the Moon. 2000 years ago people already knew it m 1 around the Earth and where it would be in the sky at different times of the year. At that time, everything about the Moon was learned by watching it c 2 in the sky.
When scientists could use telescopes to study the Moon more closely, their ideas began to change. They could see the Moon was made of r 3 . 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 g 4 millions of years earlier.
In 1969 Moon rocks were finally brought to the Earth and s 5 . Much to their surprise, scientists found that, except for water, the Moon and the Earth were made of the s 6 things. Once again new ideas were needed for this new information.
After years of study, most scientists now think t 7 the Moon was once part of the Earth. They believe very early in its history, maybe 4 billion (十亿) years ago, something about the size of Mars h 8 the Earth. This sent billions of rocks into space around our p 9 . 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 i 10 in it.
(1) __________ (2) __________ (3) __________ (4) __________ (5) __________
(6) __________ (7) __________ (8) __________ (9) __________ (10) __________
七、阅读理解
Let’s suppose it is a common day of 2060. Of course, things have changed and life is very different.
Trips to the Moon are being made every day. Taking a holiday on the Moon today is as easy as taking a holiday in Europe in 2016. At a number of scenic spots (风景胜地) on the Moon, many hotels have been built. In order that everyone can enjoy the beautiful scenery on the Moon, every room has at least one picture window. Everything imaginable is provided for entertainment of the young and old.
What are people eating now People are still eating food. But many foods now come in pill form, and the food that goes into the pill comes mainly from green plants.
Farming, of course, is very highly developed. Very few people have to work on the farm. It is possible to run the farm by just using a few computers.
People are now largely vegetarians (素食者), and they eat only bread, vegetables, fruit and so on and they don’t eat meat or fish. You see, as the number of people increases, the number of animals decreases. So people have to be vegetarians. We are healthier both in our bodies and in our minds, and we know how to deal with all kinds of illnesses. No one has to be ill any more.

Now satellites are helping to forecast (预报) the weather. They are in space, and they can reach any part of the world. The satellites take pictures of the atmosphere (大气), because this is where the weather forms. They send these pictures to the weather stations. So meteorologists (气象学家) can see the weather of any part of the world. From the pictures, the scientists can often say how the weather will change.
Today, nearly five hundred weather stations in sixty countries receive satellite pictures.When they receive new pictures, the meteorologists compare them with earlier ones. Perhaps they may find that the clouds have changed during the last few hours. This may mean that the weather on the ground may soon change, too. In their next weather forecast, the meteorologists can say this.
So the weather satellites are a great help to the meteorologists. Before satellites were invented, the scientists could forecast the weather for about 24 or 48 hours. Now they can make good forecasts for three or five days. Soon, perhaps, they may be able to forecast the weather for a week or more ahead (提前).
( ) 1. Satellites travel .
A. in space B. above space
C. above the ground D. in the atmosphere
( ) 2. Why do we use the weather satellites to take pictures of the atmosphere Because
A. clouds form there B. the weather forms there
C. the weather satellites can do it easily D. people like to collect these pictures
( ) 3. Meteorologists forecast the weather .
A. without studying satellite pictures
B. before they receive satellite pictures
C. when they have received satellite pictures
D. after they have compared the new satellite pictures with the earlier ones
( ) 4. Maybe we’ll soon be able to forecast the weather for .
A. one day B. two days
C. five days D. seven days or even longer
( ) 5. The main idea of this passage is that satellites are used in .
A. taking pictures of the Earth B. receiving pictures of the atmosphere
C. weather forecasting D. doing other work in many ways
