Hello, everyone! My name is Bob. I have a good friend. His name is Paul. He is a yellow dog. I like him very much.

Every morning Paul runs with me, and we play in the park every afternoon. Paul is very fat (胖的). He likes eating meat for breakfast. For dinner, he likes fish. Paul likes red. He has two red hats. Look! They are on the bed.

But Paul is lost (丢失的) now. Please help me. My telephone number is 3123216. My email address is paul2013@sina.com. Many thanks!

Do you know there is a special (特别的) job? The worker is not a man but a dog. They’re a kind of dog. They are like the eyes of blind (盲的) people. So we call them “seeing eye dogs”.

These dogs usually need to learn for two or three years. And then they live with blind people. Their job is to help blind people walk around (四处走). They know how to cross the street. They can also avoid (避免) dangers, like cars and bikes in the street.

Sometimes you can see these dogs with blind people. Just like other dogs, seeing eye dogs are very cute. But they are not only pets. They work hard. They can do a lot of things for blind people. They are blind people’s good friends.

One day, a baby snail (蜗牛) found that he had to carry a hard and heavy shell (壳) at any time. He wanted to know why, so he went up to his mother and asked, “Why was I born with a shell and it grew (变得) so hard and heavy?” His mother said, “Because we have no bones (骨头). We can only move slowly, so we need a shell to protect (保护) us.”

The baby snail asked again, “The caterpillar (毛毛虫) has no bones, either, and she can’t trove quickly. Why can she live without a shell?” The mother snail answered, “That’s because a caterpillar will become a butterfly (蝴蝶). She can fly high into the sky. The sky can protect her.”

The baby snail had one more question,“But the earthworm (蚯蚓) moves like us. He has no bones and he won’t become a butterfly. Why doesn’t he carry a hard and heavy shell?” His mother said, “He can dig (挖) a hole and hide (藏) in the ground, and then the earth (土地) can protect him.”

The baby snail then cried, “We are so poor! We have no protection from the sky or from the ground!” His mother smiled at him, “That’s why we have a shell. My dear, if we don’t have the shells, what will happen to us? The hot sun will dry out (干硬) our bodies and we’ll have nowhere to sleep. Without a shell, maybe we’ll die in the heavy rain. How bad it is! We don’t depend on (依靠) the sky or the ground for protection. We should depend on ourselves.”
