From a plane we can see the fields, cities, mountains or seas below. If we go into space, we see more and more of the earth. People and man-made satellites have been sent out into space to look at the earth carefully and people have learnt more about the earth in the last few years.

　　 The sea looks very beautiful when the sun is shining on it. But it can be very terrible when there is a strong wind.

　　 The sea is very big. It nearly covers three quarters of the earth. The sea is also very deep in some places. There is one place and at that place the sea is about 11 kilometers deep. The highest mountain in the world is about 9 kilometers high. If that mountain was put into the sea at that place, there would be still 2 kilometers of water above it!

　　 In most parts of the sea, there are many kinds of fishes and plants. Some live near the top of the sea. Others live deep down. There are also a lot of small living things, and lots of fishes live by eating them.

　　 The sea can be very cold. When people go down, the sea becomes colder and colder. Only some men can go down into the deep sea. But, in 1970, five women scientists (科学家) lived in the deep sea for fourteen days.

E. 66 Days at Sea

A couple from Miami, Bill and Simone Bultler, spent sixty-six days in a life-raft(救生艇) in the seas of Central America after their boat sank.

　 Twenty-one days after they left Panama in their boat, Siboney, they met some whales. “They started to hit the side of the boat,” said Bill, “and then suddenly we heard water.” Two minutes later, the boat was sinking. They jumped into the life-raft and watched the boat go under the water.

　 For twenty days they had tins of food, biscuits, and bottles of water. They also had a fishing-line and a machine to make salt water into drinking water – two things which saved their lives. They caught eight to ten fish a day and ate them raw(生的). Then the line broke. “So we had no more fish until something very strange happened. Some sharks came to feed, and the fish under the raft were afraid and came to the surface. I caught them with my hands.”

　 About twenty ships passed them, but no one saw them. After fifty days at sea their life-raft was beginning to break up. Then suddenly it was all over. A fishing boat saw them and picked them up. They couldn’t stand up. So the captain(船长) carried them onto his boat and took them to Costa Rica. Their two months at sea was over.
