Everything that humans hear is in the form of waves(波). Just as the eye sees light waves in the form of colors, the ear hears sound waves in the form of noises. The ear and the eye turn these different waves into signals that the brain(大脑) can make sense of.
The ears and brain have an amazing ability to recognize(识别) particular sounds. For example, a mother often can tell when her baby is crying even if there are other crying babies in the same room. This is because the sound of her baby’s cry has special meaning to her and the brain has recorded its importance.
The ability to recognize sounds improves with experiences. As the brain receives information about sounds from day to day, it stores the information in its memory. When the brain hears new sounds, it gives meaning to them based on the information already in the memory. This is why certain words or songs can make a person happy. Often it is not the words or songs themselves that cause this feeling. The sounds are connected to happy memories for that person.
Another hearing process controlled by the brain is to decide where a sound is coming from. One ear is usually closer to the source(来源) of a sound than the other ear is. Sound waves are stronger when they reach the ear that is closer. They also reach the closer ear first. The brain recognizes these differences and uses them to decide the location of the source of the sound.

a. The ears receive the sound waves.
b. The mother recognizes her baby’s cry.
c. The baby’s turn the sound waves into signals.
d. The baby’s cry travels in the form of sound waves.

Mike found a job in a bookstore after he finished middle school. He wouldn’t do anything but wanted to get rich.
It was a cold morning. It snowed and there was thin ice on the streets. Few people went to buy books and the young man had nothing to do. He hated to read, so he watched the traffic. Suddenly he saw a bag fall off a truck and it landed by the other side of the street.
“It is full of expensive things.” Mike said to himself. “I have to get it right now, or others will take it away.”
He went out of the bookstore and ran across the street. A driver saw him and began to whistle (鸣笛), but he didn’t hear it and went on running. The man drove to the side, hit a big tree and hurt himself in the accident. Two weeks later, Mike was taken to the court (法庭). A judge asked if he heard the whistle when he was running across the street. He said that something was wrong with his ears and he could hear nothing.
“But you heard me this time,” said the judge.
“Oh, I’m sorry. Now I can hear with one ear.”
“Cover (盖住) the ear with your hand and listen to me with your deaf (聋的) one. Well, can you hear me?”
“No, I can’t , sir.”
“You told a lie. There is nothing wrong with either of your ears,” the judge said.
