有关介质损耗描述的方法有哪些？其本质是否一致？

     Many Chinese students don't pay much attention to(注意) spoken English at school.They think

it necessary to practise speaking English in class,but not out of class.Here is a story to show you

how important it is to speak the English language freely in everyday life.

     A foreigner once got hungry and went into a restaurant in London.He sat down at a table.When

the waiter came,he opened his mouth,put his fingers into it and took them out again in order to express

that he wanted something to eat for he could not speak English.The waiter soon brought a cup of tea.

The man shook（摇动）his head.The waiter then took away the tea and brought a cup of coffee.

The man again shook his head.He tried again and again,but he wasn’t able to make the waiter

understand him.Finally another man came in.He spoke English clearly and fluently.In a few minutes,

there was a large plate of meat and vegetables on the table before him.

     So you see a man often goes hungry if he doesn’t master（掌握） a foreign language.
