When a big ship is in very rough(不平坦的) sea, it has to be able to bend(弯) a little, otherwise it may break in two. If one end of the ship is on the top of one huge wave, and the other end is on the top of another, with the middle of the ship hanging in between; or if one huge wave comes up under the middle of the ship, leaving the two ends hanging, the ship's own weight will break its back if it is quite stiff(硬的).

　　To make a big ship elastic(有弹性的) enough to avoid (避开) this danger, it has joints where the sections of the ship come together above the water-line, and these joints (连接处) open and shut slightly as the waves lift one section(部分) of the ship or another. This is enough to save the ship from breaking into pieces.

　　One day a sailor was walking along a passage-way in a big ship during a storm when he was surprised to see a boy sitting comfortably in a chair at the end of the passage-way, which was opposite one of the ship's joints. The boy had a bag of nuts beside him, and every time the ship was lifted by a wave and the joint opened, he put a nut in it. As the ship came down again, the joint closed and cracked(压碎) the nut, gently but firmly. The boy then took it out and put the next one in as the joint opened again.

Americans love sports—they love to play them, to watch them on television, and to talk about them. But this hobby sometimes has serious results—at least to the players. For example, when people play tennis, sometimes they hurt their elbow（肘部）and in this way they develop “tennis elbow” Also it is easy to hurt a knee in a football game. These injuries（损伤）happen while the player is having fun, but they still hurt.

A few months ago, Kathleen Simmons, who loves playing volleyball, hurt her knee in a volleyball game. Her doctor told her that she needed a very difficult operation（手术）or she might not be able to play again. She felt very sad and didn’t know what to do.

Then Simmons learned about “video operation”. With the help of this new science in medicine, doctors can now repair many injuries and get people back on the playing field and back to their jobs much faster. Simmons found a hospital that was using this new science and went to see the doctor there. The doctors told her the operation could help.               

For this operation, her doctor didn’t have to open her knee. Instead he put a very small camera lens（镜头）inside her knee. The lens sent back pictures, which appeared on a television screen. As he worked, he could see the inside of her knee on the TV. With the help of the large pictures on the screen, the doctor knew exactly what to do when he was making the repairs.

　　Simmons started walking five days after her operation. “My knee hurt a lot the first few days,” she said. “But I felt better very quickly.” Now, six months after her operation, Simmons can do everything she did before her injury. “It feels like a new knee,” she said. “I can even play volleyball again.”

A young college student thought that he had chosen the __36___major (专业) at a common college, so he drank every day and didn’t __37__at all. He became more and more disappointed in his life.
　 But he was never absent from Professor Yang’s biology class. He liked the course . __38__, Yang’s class was so interesting that he__39__listened carefully, never caring about whether the other students were paying attention or not in class.
　 Once he put a __40__in the homework he handed in, __41__: “Professor, it is said that today’s college__42__ are cheaper than potatoes. Do you agree?”
　 That day Professor Yang__43__ him after class. When he came, he found the professor at a table with __44__on it. They drank happily over their meal.
　 When they became half drunk, the professor produced a small __45__that was sprouting (发芽的). “Do you know how much this __46__ ?” he asked the young man. “It’s soft but poisonous (有毒的). __47__ will take it even if it’s free.” He then threw the potato away. The professor then__48__him another potato. It was half the size of a football and perfectly round. “This potato is organic (有机的). It is not only large and fresh__49__ free of pollution. It is in high demand and quite popular.”
　 The young man was impressed by what he’d heard. “Be __50__ a potato,” said the professor.
