One day a poor man was traveling on horseback. At noon, he tied his horse to a tree and then 1 to eat something. A few minutes later, a rich man came along and tied his horse to the same tree.

"Please tie your horse to another tree," said the poor man, "My horse is wild. It will kill yours." 2 the rich man said, "I shall tie my horse as I like!" He tied up his horse and had his lunch nearby. After a moment they heard a terrible 3, the two horses were fighting. They went up to them, but it was too 4. The rich man's horse was killed. "See what your horse has done!" cried the rich man. "You will have to 5 it." And he brought the poor man to Mr. Know.

Mr. Know asked the poor man some questions. But he made no 6. At last Mr. Know said, "The man is dumb. He cannot speak."

"Oh," the rich man shouted 7. "He can! He spoke to me when I met him."

"Are you sure? " asked Mr. Know. "What did he 8?"

"He told me not to tie my horse to the same tree because his horse was wild and would kill my horse."

"Oh," said Mr. Know. "So he 9 you. Then can you expect to get money 10 him?" The rich man said nothing and left silently.

Stephen Hawking, a world famous British physicist, will write a children's book with his daughter. Hawking said the book would be "a bit like Harry Potter" but without the magic. "It explains the wonders of the universe, " said Hawking, while he was on a visit to Hong Kong last week.

Hawking, 64, is probably the world's most famous scientist after Albert Einstein. He is an expert on black holes. He has put his whole life into digging into the beginning （and the end） of the universe.

"My goal is simple, " Hawking once said. "It is to completely understand the universe, why it is  and why it is there at all."

Hawking has a bad illness that stops him from moving or talking. For a period of time, he had no way to communicate except by blinking.

Now he sits on a wheelchair with a computer by his side. To communicate, he moves two fingers to control the computer's mouse. He selects his words from the screen, which are then spoken by a voice synthesizer （音响合成器）.

"I have had the disease for most of my life, " Hawking once said. "Yet it has not stopped me from being successful at my work."

Although Hawking is such a disabled man, he made great achievements. He has received many awards and prizes for his work over the years. This includes winning the Albert Einstein Award. It is the highest achievement in theoretical physics.
