Stop and listen! What do you hear? You may hear many different sounds. Some of those sounds may be noise. Noise is a loud or unwanted sound.
Noise can be caused by many kinds of machines, such as motorcycles, jet planes (喷气式飞机), farm tractors, and power motors. And, to some people, rock music is also a noise.
What happens to people who live near noisy machines or use them over a period of time? Doctors have found that these people have trouble in sleeping. And most importantly, constant (连续的) loud noise can cause loss of hearing.
Scientists use a unit of measure called a decibel(分贝) to measure the loudness of a sound. The sound of a quiet room, for example, measures 35 decibels. Talking measures between 40 and 65 decibels. Sounds from traffic and from some rock bands measure over 120 decibels. Noise at such high level causes the greatest hearing loss.

As Danny put his lunch tray onto the cafeteria table, milk spilled all over his sandwich. He sat down, hung his head forward, looking at the food in front of him. Frowning, he began peeling the soggy milk-soaked bread (浸透牛奶的) from his sandwich. “This is the worst thing I’ve ever done!” he said, “It’s not that bad,” said his friend Elena, who was sitting across from him. “Just get another sandwich.”

“Sandwich? What sandwich? I am talking about the talent contest. It’s only two weeks away and I don’t know what I’m doing! Everybody will laugh at me. There’s no way to avoid it!”
“Don’t be so negative, Danny,” said Elena as she rolled her eyes. “You’re going to be great, You’re very capable. You have the skills to do just about anything.”
Danny moved his lunch tray to the side and rested his head on the table.
“Sit up Danny,” ordered Elena, “I have an idea. Let’s brainstorm a list of things you could do. We’ll divide the list into categories or groups. Let’s start with music. You play the piano, right?”
“I stopped taking lessons in the third grade,” said Danny.
“What about singing a song?” suggested Elena.
Danny shook his head no. “Let’s move on to another category.”
“What about performing magic tricks?” asked Elena, as she twisted thin strands of hair around her finger.
“I don’t know how to play magic tricks!” Danny almost shouted. “Elena, how did I get myself into this huge mess?”
“Stop being so…” Elena paused, “That’s it, DRAMATIC!” Elena shouted excitedly. “You could do a dramatic reading. You definitely have the talent for it. Mrs. Pace always calls on you to read aloud in class. You could read a play aloud. Maybe you could even get extra credit from Mrs. Pace. She rewards students with points for doing extra reading work.”
Danny thought for a minute. Then he smiled. “Elena,” Danny said, “You are a great friend!”
Elena smiled back. “I just want to make sure you are a bright, shiny star when you step out on stage.”
【小题1】Elena and Danny were talking ______.
