We are often told to pay attention to what our mothers tell us. Most of us enjoy listening to our mothers speak. Scientists have found that compared to other people’s voices, our brains greatly prefer(更喜欢) the voices of our own mothers.

Scientists at Stanford University, US, recently studied this. They scanned (扫描) children’s brains while they were listening to different sounds, including their mothers’ voices. They found that 97 percent of the time, children could recognize their mothers’ voices at once.

Hearing their mothers’ voices makes children’s brains more active. We usually just use one part of our brain to deal with sounds when we hear something. But when we hear our mothers’ voices, many parts of the brain, including those in charge of (负责) reward (奖赏) and emotion (情感), start to work as well.

Why do we respond so strongly to our mothers’ voices? It starts even before we’re born. When children are still in the womb (子宫) or have just been born, they hear their mothers talking. This makes babies feel comfortable and teaches them language and social skills, even though they are still very young. The babies learn to recognize(辨别) their mothers’ voices as a rewarding (奖励性的,有益的) sound. Later, when this sound is heard again, more attention is paid to it.

Some sounds are necessary for our survival (生存) or bring us pleasure. These sounds are recognized by our brains as rewarding sounds. Most human voices are not recognized in this way, since we hear them so often. But mothers’ voices are different. They bring us a lot of comfort.

A.Why we should listen carefully to our mothers. B.Why we prefer to hear our mothers’ voices.

A.Because they can recognize their voices quickly.

B.Because their voices make them more comfortable.

C.Because they can get a reward for doing so.

D.Because they can get love from their mothers.

Dick often goes traveling in the summer holidays and almost always has a good time. But he was out of luck this summer.

He went to an old temple(庙) on a high mountain by himself. On his way there, it began to rain hard and he went down the mountain as soon as possible. When he got to the foot of the mountain, he found the bridge was under the water. So he had to spend the rainy night in an old farm house. He was so hungry that he hardly fell asleep.

The next morning the rain stopped and he found the bridge was damaged. He saw the river was not too deep(深的) and tried to swim across it. In the middle of the river, the water nearly washed him away. Luckily, two farmers saved him, but he lost his bag. They gave him some food and dry clothes. He thanked them and went to the nearest town to call up his parents. At the end of the street, Dick found a small hotel and went in. He asked the price for a room. “A room on the first floor is twenty dollars, on the second floor, fifteen dollars, and on the third, ten dollars,” answered the waiter(服务员). The young man had only eight dollars in all his pockets(口袋). He said thanks and was leaving.

The waiter asked, “Don't you like our hotel?”

“Yes, it's good,” said Dick, “but it's not tall enough!”
