Imagine sitting in a boat in the ocean. The sky is blue, the sun is out, and the water is clear. Suddenly, you notice something moving in the water, so you stand up to get a closer look. 【小题1】 And it’s a fast swimmer. It jumps out of the water and then it’s gone. You’ve Just seen an orca（虎鲸）!

Orcas, also called killer whales, live in every ocean on Earth. 【小题2】 Firstly, orcas are not really whales. They’re in fact the largest member of the dolphin family. Secondly, they are usually harmless to humans. Orcas’ attitudes toward humans depend on human attitudes toward orcas.

Orcas are quite playful. They live in groups called “pods”, with between 5 and 30 orcas, for their whole lives. 【小题3】 The orcas’ friendly nature is very useful for finding food. Orcas hunt in their pods and then work together to kill.

There are about 40 orcas in aquariums（水族馆）all over the world. 【小题4】 The most famous orca, Keiko, who appeared in the film Free willy, was in an aquarium. Later scientists tried to help him go back to the wild. They were successful. Keiko became much healthier when he was moved from the aquarium to the sea. However, Keiko liked humans more than other orcas. 【小题5】

This is a story about a monkey. An old man had a monkey. The old man liked the monkey very much. The monkey was very clever. When birds came to the garden, he drove them away. He also helped the old man in many other ways. One hot afternoon in summer, the old man was asleep in his chair in the garden. A fly（苍蝇）came and sat on the old man’s nose. The monkey drove it away. Soon the fly came back again and sat on the old man’s nose. Again the monkey drove it away. Again and again, the monkey became very angry. He jumped up, ran to pick a large stone. When the fly was on the old man’s nose again, the monkey hit it hard with that stone. The fly fell off, but the old man’s nose was broken. Well, many people, even our friends, sometimes do things just like the monkey. They do things too quickly but they don’t think much before they do. Maybe they sometimes bring us trouble, though they mean to do something good.
