    Little Peter is a boy of nine. He began to go to school when he was six, and now he is in Grade Three. He lives not far from the school, but he is often late for class. He likes watching TV in the evening and goes to bed late, so he can't get up on time in the morning.

    This term, Mrs. Black, Peter's aunt, teaches music in Peter's school. She is strict（严格的）with Peter and often tells the boy to obey the school rules and come to school on time. Yesterday morning, Peter got up late. When he hurried(赶紧) to school, it was a quarter past eight. His aunt was waiting for him at the school gate.

    "You are ten minutes late for the first class, Peter," Mrs. Black said angrily. "Why are you often late for class?" "Every time, when I get to the street corner(街道拐角), I always see a guidepost(路标). It says SCHOOL—GO SLOWLY!"

Have you ever read stories of Sherlock Holmes—a famous detective? Here is one of his cases.

Stapleton, Charles' younger brother, found that he would inherit (继承) the Baskerville lands if Charles and his nephew(侄子) —Henry both died.

    Charles who had a weak heart believed super natural stories. After knowing this, Stapleton had the idea of buying a huge hound, and of using the phosphorus(磷) to make it shine like the hound in one story.

    Then Stapleton asked his friend Laura to write a letter to bring Charles to the moor gate on that sad night. The hound, which was shining with phosphorus, chased Charles down the Yew Alley. Charles' fear was so great that his weak heart stopped, and he died but the animal did not touch the dead body. There was no sign of murder. It was difficult for Holmes to find the murderer.

    Two weeks later, Stapleton learned that Henry had reached England. He took his wife and the hound with him. He wore a false beard and followed Henry in London. He wanted to use the same way to murder Henry there. He needed something to give the hound Henry's smell, so he paid a woman at Henry's hotel to steal one of his shoes. The first one was a new one, which was no use for the hound, so it was put back. And then another older shoe was stolen. Before he was ready to murder Henry, he wasn't sure if his wife would keep his secret, so he did not tell her the truth. He locked her up in their hotel. She knew that he must have some evil plans. She sent Henry a letter which was made of words cut from a newspaper.

    After receiving the letter, Henry realized he was in great danger and it must have something to do with his uncle Charles' death. So he asked Holmes for help.

    We often hear stories of animals rescuing people .But now someone has managed to return the favor .

The event took place one snowy January morning Thomas Smith was walking his dog, Jack, in the park." As I was walking, I just saw Jack running onto the ice towards the ducks in the middle, and then he fell into the water and couldn't climb out, "said Smith. He realized he had no choice but to try and save his dog." someone else told me the lake was only one - meter deep, but it was at least twice that. I had to break my way through the 6- cm ice. Finally, I got Jack by the neck, and pulled him out. I don't think I have ever felt so cold by the time we got back to dry land. And when we got there, everyone was asking if Jack was okay—— no one was particularly worried, about me!"

    A neighbor, Julie Brown, saw it all happen."The dog went onto an icy lake. All of a sudden, it started to go under. There were crowds of people around, and they were all shouting and screaming. Before I knew it, the owner Smith was in the water forcing his way through the ice. I can't begin to imagine how cold it was. Everyone was very nervous, but he was as cool as a cucumber — he just crawled back out, put the dog on its lead, and went home."

    Many regard him as a hero, but Mr. Smith is quite laid- back about it."Most dog owners are the same as me.They would do what I did without a second thought. But in the future, I'm going to make sure he's on lead near any ice ponds,

    Pets are members of our family. Would you do the same for them?
