1. Divide the article into three paragraphs according to the characters (first old birds and birds, then old birds and birds and greedy people, and finally old birds and birds).

The first paragraph is from (1) to (12).

The second paragraph is from (13) to (22)

The third paragraph is from (23) to (25)

2. Summarize the main content with six elements.

As an advanced human, because greed is not as happy as birds, birds don't understand what greed is and want to see it. Someone was walking in the forest, and the old bird fell beside him, and people caught it. The old bird told him that there are three wise sayings that can make a fortune. Every time the old bird said something, he made a request, and the man agreed. After the first sentence was finished, the old bird was released. After the second sentence, when the old bird flew to the tree and said that it had 120 grams of big gems in its stomach, the man regretted it. When he knew that an old bird with less than100g had a big gem of120g in its belly, the man was dumbfounded and embarrassed. A bird played a trick on a man, and the bird knew what greed was.

3. What does the old bird think in the underlined sentence? Try to think in context.

Advanced creatures in human history are not as happy as birds because of greed. This bird doesn't understand. I want to show him. The man in front of him is greedy. As soon as he heard that there are three famous sayings that can make a fortune, he became impatient. But I can't finish it at once, or he will eat it. I want to say it sentence by sentence. Gradually get rid of him, I pretended to be calm and said to him.

4. From the perspective of birds, add appropriate words before "greed" to form three subheadings (dots) respectively.

Greed (knowledge) greed (understanding) greed
