完形填空

    In class,I was telling my students the story 1 the hare and the tortoise. 2 the end I said: “Everybody, 3 slow and steady (稳) wins the race. Don't you think there's something to learn 4 the tortoise.”

    Sonny opened his eyes wide. “Do you 5 next time. When I'm entering 6 the 7 race, I should wish that Bily 8 Tom and Sandy would all fall 9 half-way?”

    I was shocked (着慌),“But the tortoise didn't wish the hare would fall asleep!”

    “He must have wished that.” Sonny said,“Otherwise how could he be 10 stupid to race with the hare? He knew very well that the hare ran a hundred times 11 than he himself did. ”“He didn't have 12 a wish. ” I insisted,“He won the race, by perseverance(坚持) by pushing on 13 .”

    Sonny thought for a 14 .“That's a lie! He won it because he was 15 . If the hare hadn't happened to fall asleep the tortoise would never have won the race. He could be 16 steady us you 17 or a hundred times steadier, but he'd never have won the race! That's sure. ”

    I gave 18 . Today's children are not like 19 we used 20 be, they are just hopeless.

　　The sea is the largest unknown part of our world. It covers seventy－one per cent of the earth. There is still much to be discovered about working to explain its mysteries(神秘).

　　Some are studying ways of bringing the ocean's huge supply of water to the deserts of the world. Others hope to control the weather by learning more about the exchange of heat and moisture(潮湿) between the ocean and the air. Others are studying the ways in which sound travels and is affected by water and heat.

　　One of the most interesting projects in oceanography(海洋学) is the work of mapping the ocean floor. Only a very small part of it has been mapped. This was not important when only surface ships sailed the world's ocean, but it can mean the difference between life and death to men in submarines(潜水艇).

　　Long ago there was only one way to find out how deep the ocean was. A seaman could throw a weighted rope over the side of his ship. Then he pulled the rope up after it had reached the bottom. But this was not a very exact way of measuring.

　　In the 20th century a better way was found. Sound was used to measure the ocean. Seamen did an experiment. They dropped a number of devices that would burst with a loud noise when they hit the bottom. And a little instrument measured the time it took for the sound to reach the ship. This has helped the scientists to map the ocean floor.

　　Underwater photography is also important in mapping parts of the ocean floor.

　　Around the edges of the continents the ocean floor is flat and the water does not become much deeper for about 30 miles.

　　The area near the continents, where the water is not so deep, is the place where the ocean's greatest riches in marine(海洋的) life are found. Below these living creatures and plants are the largest unknown quantities of mineral.

　　At the end of the flat part the sea floor suddenly drops down forming deep hollows which are shaped like bowls. These huge hollows hold most of the world's water.
