Sammy looked out of the classroom window at a bird in a tree. He saw a worm (小虫) in the bird's mouth. "Wow!" he whispered as he looked at the bird eating the worm.
"Sammy!" his teacher Mr Maxwell said loudly.
Sammy jumped and knocked his science book off his desk. Everyone in the class laughed and Sammy blushed. This was the third time today he had been caught not paying attention to the science lesson. It was just so easy to get distracted (分心的) when people read aloud from the science textbook!
It wasn't that Sammy didn't like science. He loved to learn about machines, Earth and animals. He even thought bugs and plants were great. He wanted to go outside and see how a snake lived. He wanted to watch plants growing from the ground as they did last month. He just didn't want to read about these things.
Sammy thought Mr Maxwell would surely understand. "There was a bird with a worm in its mouth…" Sammy began. Then he saw thefuriouslook on his teacher's face. Sammy decided that he had better stop talking before Mr Maxwell became any angrier.
