Man's best friend
Dogs are often called "man's best friend", and for good reason. They have been with humans for about 15,000 years. During that time, they have helped humans in many ways.
In the past, dogs helped people hunt for food. They also guarded the home and kept people warm on cold nights. Today, dogs still play important roles. Some dogs are police dogs. They help the police catch criminals and find missing people. Others are guide dogs. They help blind people walk safely on the street. Some dogs even work as therapy dogs. They visit hospitals and cheer up sick children and old people.

七、任务型阅读
阅读下面短文,根据短文内容回答下列问题。
The clever octopus
The octopus is a very clever sea animal. It has eight arms and a soft body. It lives in the ocean, usually in coral reefs or on the seabed.
Octopuses are very good at hiding. They can change the color and texture of their skin to match their surroundings. This helps them avoid predators like sharks and whales. They can also squeeze their soft bodies into very small spaces, which makes it easier for them to hide.
Octopuses are also very smart. They can solve simple problems. For example, they can open jars to get the food inside. Some scientists even think that octopuses have their own culture. They learn from each other and pass on their knowledge to the next generation.
However, octopuses have a short life. Most of them live for only one to two years. Also, they are in danger because of pollution and overfishing. Their homes are being destroyed, and many are caught by fishermen.
We need to protect the ocean environment to save octopuses and other sea animals.
1. Where does the octopus live?
2. How many arms does an octopus have?
3. What can octopuses do to hide from predators?
4. Can octopuses solve simple problems? Give an example.
