We are all busy talking about and using the Internet，but how many of us know the history of the Internet?
Many people are surprised when they find that the Internet was set up in the 1960s.At that time，computers were large and expensive .Computer networks didn’t work well. If one computer in the network broke dow
n,，then the whole net-work stopped.. So a new network system had to be set up. It should be good enough to be used by many different computers. If part of the net-work was not working, information could be sent through another part. In this way computer network system would keep on working all the time.
At first the Internet was only used by the government, but in the early 1970s,universities, hospitals and banks were allowed to use it too. However, computers were still very expensive and the Internet was difficult to use. By the start of the 1990s, computers became cheaper 
and easier to use . Scientists had also developed software that made “surfing” the Internet more convenient.

It is natural that children are curious about the world around them. For example, they want to know how their hearts beat. They want to know why the ocean water tastes salty.
As children gr
ow up, they become curious about different kinds of things. When they are babies, they are interested in the parts of their bodies and in the smiles of their mothers. They become interested in the physical world around them: the plants, the animals, the sky. Later, they become interested in the things that people have made: wheels, bicycles, cars. And when they are adults, their curiosity continues. Sometimes this curiosity leads to a career (生涯、职业) in science.
Scientists spend their lives trying to find out about the world．Those who work with the earth sciences study the earth, the oceans, and the skies. Other scientists who study living things work with the biological sciences. A third group of scientists study the physical sciences, e. g. physics, chemistry.
These scientists have already discovered a lot about our world．For example, they tell us why your heart beats fast when you run. They say that when you are quiet, your heart normally beats sixty-five or seventy-five times a minute. Your heart is a pump (泵) that pumps blood to all parts of the body. The blood carries oxygen and nutrition. When you run, your muscles work very hard and use the nutrition that the blood carries to them. The muscles need oxygen, too . So your brain sends a signal to the heart. The signal means that the muscles need more nutriti
on and oxygen. Then the heart beats fast and sends blood quickly to the muscles. It may beat 90 to 140 times a minute.
Of course, scientists cannot answer all of our questions. If we ask, “Why does the ocean water taste salty” scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. But then we ask , “What happens to the salt in the ocean? The ocean does not get saltier every year.” Scientists are not sure about the a
nswer to this question.
We know a lot about our world, but there are still many answers that we do not have, and we are curious.According to the passage, which of the following statements is true?
| A．People of different ages are interested in different things |
| B．People in different countries are interested in different things. |
| C．Men and women are curious about different things. |
| D．People are curious in the same way. |

When you run, your muscles need ____.
| A．more nutrition and oxygen | B．more signals | C．more salt | D．water |
A rock cracks _____.
| A．in wet regions | B．in dry regions |
| C．at very high or very low temperatures | D．when salty water falls in |
