When it was getting dark, a wolf was walking along the road. Then he was surprised to see his huge shadow(影子) under his feet.
“Wow, I didn’t know I was so big!” The wolf was happy to know it.
As time went by, the sun was going down and his shadow grew bigger and bigger, so it looked like a giant.
“Oh, look at my shadow. I’m so big!” The wolf thought that he was as big as his shadow. “I’m huge and excellent. I don’t need to be afraid of the lion.”
From then the wolf walked with his shoulders open. He thought of himself as the king of the forest.
“Why should I fear the lion? Lion! Come out! Here is your match（对手）.”It made the lion very angry, so he went to see the wolf.
“Here I am. I heard you said you could beat me. Now I’m here. Why don’t you prove it?”
The lion’s sharp claw(爪子) hit the wolf’s head hard. The wolf was knocked out. “Ah, help me!”
But it was too late when the wolf got to know that he wasn’t as big or strong as his shadow. Unluckily, he became the lion’s delicious supper.

Are you carrying too much on your back at school? I’m sure lots of children of your age will say “Yes”. Not only the students in China have this problem, but children in the United States also have heavy school bags.
Doctors are starting to worry about young students’ back and neck because their school bags are too heavy for them.
“It’s hard for me to go upstairs with my heavy bag,” said Rick Hammond, an ll-year-old student in the USA.
Rick is among students who have school bags with two straps(带子),and many other students choose rolling(有滚轮的) bags.
