  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.

Meeting the English Family

  Rosa and her classmates were in a street in West London. The sky was dark. This was Rosa's big day, her first day in England.

  Rosa got out of a taxi. The driver carried a very heavy bag for her. They walked through the rain to the front door of a big Victorian house.

  A small girl opened the door. She was four years old. Her brother stood behind her. He was only two years old. One minute later, a young woman came to the door.

  “Welcome to Wembley!” she said and she offered Rosa her hand.  “These are my two children, Elisabeth and Isaac” “Pleased to meet you, Mrs. Frost! said Rosa with a strong Spanish accent.

  The two children ran back into the living room.

  “Don't worry about them! They're a little shy. And please call me Diana! Now let me show you your room and then we can have a nice cup of tea. Or would you like some coffee?”

  “I'd like to try a cup of English tea, made in England.”

  “This is your bedroom. There's a nice view (视野) of the football stadium (露天体育场) and here's a little desk where you can study. The bathroom and toilet are just opposite your door. Now I'll go and put the kettle on.”

  “Excuse me. What's a kettle?”

  “In England, we use a kettle to make hot water, we can then put the hot water in a teapot or use it to make coffee.”

  Rosa was happy with her new home, but she was a little puzzled (困惑的). Perhaps her mother Maruja was right. The British were not normal people. They did not kiss when they met and they lived in large Victorian palaces. Their favourite drink was tea and they used strange metal kettles to make the water hot. What was she going to say to Elisabeth and Isaac? How could she make friends with two shy English children? Perhaps the answer was in the big, black psychology (心理学) book.
