Mr. Black's office was only 5 kilometers away from his house, so he could go home to have lunch every day. But when he got home at noon, he had to drive another place to park his car, then walked back home. Because he found many cars outside his house and there was no room for his own car. This made him very angry.

One day, he put up a board in the garden facing the road

“Really?” he asked with a smile. “Look again!”

“Oh, Dear!”she started to laugh, "You are really clever!”

Jane Goodall is a famous scientist. For more than 40 years, Goodall lived mostly in Tanzania in East Africa, studying chimpanzees.

    As a young child, Jane Goodall was interested in animals. She grew up in the English countryside and was always climbing trees or riding horses.

When Jane was 23, she got a chance to go to Africa even though she had never been to college，she got a job with a famous scientist named Louis Leakey.

One day Louis Leakey said he needed a volunteer. He needed someone to go to a lake in Tanzania to study a kind of chimpanzees. Jane was excited.

    On July 16,1960, she began her exploration（探索）. At first, the chimpanzees ran away from Jane. But with time passing，they got used to her being around.

    Every day，Jane would follow the chimpanzees，taking notes on their behavior. She learned many new things about chimpanzees. She watched how a chimpanzee made a tool. She learned how some chimpanzees became good leaders. She watched how mother chimpanzees raised their children. She watched animals get angry and get upset. She wrote everything down so others would understand animals as she did. She learned that if you pay really close attention to animals，you will understand what they are “saying”.

    Shaking the head doesn't always mean 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!"
