Once there was a man named Tom. His eyes were in great pain. He visited the best doctors in the world. He also tried different kinds of medicine. nothing helped. One day, Tom met a famous eye doctor. He advised the man to look only green things for a long time.
It was a very strange (suggest), but Tom wanted to try it. He (buy) boxes of green paint and painted everything green in his house. To his surprise, it (real) worked! The pain was starting to go away.
Several weeks later, friend in white visited Tom. While he (walk) towards Tom's house, Tom came running with a box of green paint and poured(倾倒) all the paint on him. The friend was very angry. Tom first said sorry to (he), and then said that he had to do this -- because he needed (see) green things only.
The friend laughed(大笑) aloud after hearing that. "Why did you paint everything green?" he asked. "It would be much (easy) if you put on a pair of green glasses! You can paint all things green, but you cannot paint the whole world green!"
