Mike was an ordinary cat. He had two ears, four paws（爪子）and a short tail. Wait a minute! A short tail? All the other cats that Mike had seen had 1ails, so Mike decided to2a long tail.
Mike travelled far and wide, trying to 3a long tail. Along the way, he spoke with many cats that had long tails. “Mike, what a (n) 4 cat you are!” they would say. “We have never seen a cat with a short tail.” The cats would sit around Mike, 5all kinds of questions about what it was like to have a short tail. Mike often found himself telling stories of how he could sleep in front of warm fireplaces, never having to6 whether someone was going to step on his tail. It wasn't long before Mike became 7! More cats came to him to hear his8 stories.
Soon, Mike 9 that he had left home in order to find a long tail! Maybe being a cat with a short tail wasn't so 10. Because of his unique (独一无二) tail, Mike had made many friends. “I guess being one of a kind is not so bad after all,” Mike thought. “I think I'll keep my short tail.”

Josh stepped to the edge (边缘) of the platform. This was the third time he had come up here, and for the third time he turned around and walked back to the ladder, afraid to make the dive from the high platform.
“I had made good dives at lower levels,” he thought. “Mr Barry, the teacher, had even said that if I didn't want to dive from that height, I didn't have to.”
Standing on the ground, Josh stared (盯着) up at that high dive platform. Suddenly, Mr Barry began walking toward him. “How are you doing, Josh?” he asked.
“I'm all right, Mr Barry. I just got a little frightened up there,” Josh said.
“Don't worry about it, Josh. You know, when I was young, I got scared up there too,” Mr Barry said.
“So how did you take the courage to dive from up there, Mr Barry?” Josh asked.
“I decided that I had to stop thinking about it. I just climbed up the ladder, ran to the end, closed my eyes and jumped off the board.”
Josh took a deep breath, turned around and started walking back to the ladder that led to the high dive platform. He knew it was something he would have to do. Even if it wasn't today, he would do it someday.

A marathon is an endurance (忍耐力) race which covers 26 miles, 385 yards (42.2 km). It is a race for the strong. To run this race, one must have great endurance.
The history of this tiring race dates back to a war. The war was between the Persian Empire and the Greeks. It was in the year 490 BC. The war took place on a plain (平原) called Marathon.
The Greeks won. After the war, a man was chosen to announce that the Persians had been defeated (打败) in the battle. The man ran from the battlefield of Marathon to Athens. He ran at top speed without stopping to rest. When he reached Athens, he told the news and died.
In 1896, the marathon race was included in the first modern Olympic Games in Athens. The race was to remember the runner. It was 24.85 miles (40 km), the distance that the man had been asked to run to give his news.
All marathons today are a little longer than the one in the first modern Olympic Games. Distance was added at the 1908 O1ympid Games in London, The distance was changed to 26.22 miles to cover the ground from Windsor Castle to White City stadium, with the 2.2 miles added on so the race could finish in front of the Royal Box.

Objective (目标): Students will: Explain and show what to do if their clothes catch fire. |
|
Materials（材料）: Red, orange, and yellow paper __________, tape A song named Stop, Drop and Roll |
|
Class Time: 40 minutes |
|
Activity: Note to teachers: Before the activity, you should cut 10 to 15 pretend flames out of the red, orange, and yellow paper. The thought of being near a fire is pretty scaring, right? Does anyone know of any rules that can help keep you safe when there's a fire in your house? What if your clothes catch fire? Well, if that ever happens, you may run as fast as you can. However, running would actually make the fire get worse because the air would cause the fire to get bigger and spread. Instead, if you find that your clothes or hair has caught fire, you should immediately stop what you're doing, drop to the ground and roll around on the ground until the fire goes out. Rolling around on the ground smothers (闷灭) the fire and doesn't allow it to get any air. This causes the fire to go out. Today, we're going to practise stopping, dropping and rolling. I have some pretend flames here. I'll tie these pretend flames on your clothes with the tape. Then you'll have to stop, drop and roll on the ground until all the flames fall off your clothes. Two people can go at a time. Everyone will get a chance to practise. While each child is stopping, dropping and rolling, the rest of us will sing the Stop, Drop and Roll song. |
Scientists believe there are some things in the sky that we will never see. We won' t see them with the biggest telescope in the world on the clearest night of the year.
That's because they're invisible (看不见的). They're the dead stars called black holes.
You might find it hard to imagine that stars die. After all, our Sun is a star. Year after year, we see it up in the sky, burning brightly, giving us heat and light. The Sun certainly doesn't seem to be getting old or weak. But stars do burn out and die after billions of years.
As a star's gases bum, they give off light and heat. But when the gas runs out, the star stops burning and begins to die.
As the star cools, the outer part of the star is pulled in toward the center. The star turns into a smaller and smaller ball. If the star is very small, the star ends up as a cold, dark ball. If the star is very big, it keeps being pulled inward until it's packed together tighter than anything in the universe.
What pulls the star in toward its center with such power? It's the same force that pulls you down when you jump — the force called gravity (重力). A black hole is so tightly packed that its gravity sucks (吸) in everything — even light. The light from a black hole can never come back to your eyes. That's why you see nothing but blackness.
