    The world is full of amazing things. Today, I'm going to talk about something amazing.

    We have lots of things to do every day, so many of us will be tired after a busy day. They all choose sleeping to have a rest. But do you know that sleeping can consume（消耗） many calories. The energy consumed is even more than watching TV. If you want to have a good health, I think you can't sleep too much.

    Do you like animals? There are a lot of surprising things they can do. Goldfish are a lovely kind of fish. Most goldfish have quite a short life — only 6 to 7 years. Once, the goldfish called Freb had a very long life. It lived up to 41 years. It was the oldest goldfish in the world. Now if people take good care of the goldfish, they can live more than 10 years. Animals are our friends. We should know more about them and give them a good home. Do you have any interesting stories about amazing things? If so, tell us. Let's share them together.

①文本的内涵，则只有经过读者心灵的填充．同化，才能投胎受孕成形
②本来我们不叫“文本”，而叫“课文”
③文本的意义，是由读者决定的    
④课文,是客观存在，其意义是确定的，不以读者的主观意向为转移     
⑤这两个词，在英语里都是text，原来都是正文．本文．原文的意思
