“Cool” is a word with many meanings．Its old meaning is used to express a temperature(温度) that is a little bit cold．As the world has changed，the word has had many different meanings now．
“Cool” can be used to express feelings of interest in almost anything．
When you see a famous car in the street，maybe you will say，“It’s cool．”You may think，“He’s so cool，”when you see your favorite footballer．
We all maximize（扩大） the meaning of “cool”．You can use it instead of many words such as “new” or “surprising”．Here’s an interesting story we can use to show the way the word is used．A teacher asked her students to write about the waterfall（瀑布）they had visited．On one student’s paper was just the one sentence，“It’s so cool’’．Maybe he thought it was the best way to show what he saw and felt．
But the story also shows a scarcity（缺乏）of words．Without “cool”，some people have no words to show the same meaning．So it is quite important to keep some credibility（可信性）．Can you think of many other words that make your life as colorful as the word “cool”？ I can．And I think they are also very cool．
【小题1】We know that the word “cool’’ has had ________.

The idea of what shaking the head means is not always the same in different countries. Maybe some visitors would be surprised when they first come to India. When they talk to an Indian, they would find he would often shake his head. The visitors might think that the Indian doesn’t like what they say. But in fact, they would be completely wrong.
Indians always shake their heads when they talk to others. It doesn’t mean “No”. If someone wants to visit India, he should know this, or he will be in trouble.
One day, a foreign officer went to India on business. He hired a car and asked an Indian to drive him. When he told his driver to take him to his office, the Indian shook his head at once. The officer said again and the driver shook his head again. At last the officer, of course, got angry.
“How dare you refuse my order?” he shouted, “Drive me to my office at once!”
The driver answered in quite a loud voice, too. “Yes, sir!” But to the officer’s surprise, the driver shook his head at the same time.
The car started and the foreign officer was now too surprised to say a word. He thought about it for a while, and then he nodded with a smile, “‘No’ means ‘Yes’ here!”
