John was a very strong man. Once he got a job of cutting wood in a forest. His boss gave him an axe and showed him the area where he should work.
The first day, John cut down 18 trees. "Good," the boss said, "keep it up!" John was encouraged by the words of the boss and tried harder the next day, but he could only cut down 15 trees. The third day he tried even harder, but he could only cut down 10 trees. Day after day he was cutting down fewer and fewer trees.
"I must be losing my strength," John thought. He went to the boss and said that he could not understand what was going on. "When was the last time you had sharpened your axe?" the boss asked. "Sharpened? I had no time to sharpen my axe. I have been very busy trying to cut more treesl" said John.
The moral of this story: While John was working hard, he didn't think about how to do his job better. Our lives are like that. We sometimes get so busy that we don't take time to sharpen our skills. Many of us never learn new skills. We think that whatever we have learned is enough. However, in some ways, sharpening our skills from time to time is the key to success.
小題1:When did John cut the most trees?
A．The first day.B．The second day.C．The third day.D．The fourth day.
小題2:John was cutting down fewer and fewer trees. He thought_______.

小題3:What can we learn from the story?

B．Hard work is the only key to success.
C．It's important to take time to sharpen our skills.
D．It's a waste of time to sharpen the axe.

When Tai Lihua was two years old, she lost her hearing because of a fever, then she became mute (啞的), too. From then on, her world was silent. But she didn’t know this at first. At the age of five, when her schoolmates in kindergarten (幼兒園) played a game about sound, she discovered that she was different from others. She was very sad about it.

There are about fifteen hundred languages in the world。But only a few of them are very important．English is one of these．Many people use it，not only in England and the USA，but also in other parts of the world．About 200，000，000 people speak it as their own language．It is difficult to say how many peopie are learning it as a foreign language．Many millions of people are trying to do so．Is it easy or difficult to learn English?Different people may have different answers．Have you ever noticed ads(廣告)of this kind in the newspapers or magazines?“Learn English in six weeks，or give your money back…”，“easy and funny…”，“Our records and tapes help you master English in a month”．Of course，it never happened quite like this．
