     This is a story from the Ming Dynasty period of China's history. There was a miner official called

Wan Hu, whose dream was to "fly to the moon". One day he tied himself to a chair with 47 "rockets"

and disappeared into the sky and was never seen again. Hundreds of years later in 1969, when US

astronaut Neil Armstrong stepped down from Apollo 11 and set his foot on the moon's surface, the

dream of Wan, as well as the rest of humankind was realized. To honor Wan, a crater (环形山) on

the far side of the moon is named after him.

   Mankind has been able to change the world for the better because there are people like Wan who

never stopped pursuing their dreams.

   "I have a dream!" American civil rights leader Martin Luther King once said. It was that dream that

helped black Americans to get equal legal rights.

   To realize his dream of feeding everyone in China, Yuan Longping worked in fields day and night

and invented hybrid rice that now feeds almost one quarter of the world's population.

   Dreams are important because they give us vision (远景). We grew great with them. They provide

direction for our life. With dreams we set goals and make plans, so we can change our present situation

for the better. And our dreams appeal to the likeminded. As individuals we are better off with

dreams-and so are our families, communities and society. Life would be dull without a dream.

   When we have a burning desire and we decided to go after it we are full of enthusiasm. As American

novelist Louisa May Alcott, who wrote Little Women said: "Far away there in the sunshine are my

highest aspirations". I may not reach them, but I can look up and see their beauty, believe in them, and

follow where they lead.
