Jack worked in a shop that sold clocks. He was always telling Harry 26 a new clock. But Harry, 27 lived next door to Jack, said he didn’t need one.
“ 28 needs a clock,” Jack said. “How do you know when it’s time to get up?”
“My landlord Mr. Smith turns on his radio at seven o’clock and listens 29 the news,” Harry said. “That’s my morning call.”
“Ok. But how do you know when to go to work?”
“By the time I 30 my breakfast, it’s eight o’clock, time to leave for the office. Then I walk there. When I arrive at my office, it’s nice o’clock. That’s 31 time I start work.”
“Ok. But how do you know when it’s time to go home?”
“The factory bell 32 ” Harry told him.
“But how do you know when it’s time to go to bed?”
“The television programs come to end.”
By now Jack was really 33 . “Ok,” he shouted. “Now tell me what would happen 34 you woke up in the middle of the night and wanted to know the time.”
“That’s easy,” Harry said, “I would knock heavily on 35 wall. Then you would shout at me, ‘What are you doing knocking on my wall at three o’clock in the morning?’”

Stop! Listen! What do you hear? You may hear many different sounds. Some of those sounds may be noisy. Noise is loud and unwanted sound.
Noise can be caused by many kinds of machines, such as motorcycles, jet planes, tractors and so on. And, to some people, rock bands are also noise.
What happened to people who live near noisy machines or use them over a period of time? Doctors find that these people have trouble in sleeping, But, most important, constant loud noise can cause a loss of hearing.
Scientists use a unit of measure called a decibel 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.
