We usually believe what our brain tells us, but there are some amazing facts which show that the brain tricks us. As a result, we think we can see something that is not actually there or we ignore（忽视）things that actually are there.

Scientists Daniel Simons and Christopher Chabris have researched this phenomenon（现象）, which they call “change blindness”. Their experiments show how we sometimes just do not see what is in front of our eyes because 　　　　　　　　　　　　　 .

Here is one of their most famous experiments. In this experiment, the participants（参与者）were shown a video of two groups of people (one group in white T-shirts and one group in black T-shirts) who passed basketballs around in a hallway. Each group had three members. Simons and Chabris asked the participants to count how many times the white team passed the ball. While the two teams were passing their balls around, a person dressed up as a big bear walked through the group and stopped to look at the camera. Simons and Chabris found that about half of the research participants did not notice the big bear.

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(和……相比较) to other people's voices, our brains greatly prefer the voices of our own mothers.

Scientists at Stanford University, US, recently studied this. They scanned 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(认出) 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(作出反应) 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 their mothers' voices as rewarding(奖励性的) 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.

1.What is the story mainly about?

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

C.How we recognize our mothers voices. D.How we respond to different kinds of sounds.

2.What will happen when children hear their mothers’ voices?

A.Many parts of their brains become active. B.They will need time to recognize the voices.

C.Their language skills start to improve. D.They will remember some bedtime stories.

3.According to Paragraph 4, why do children pay more attention to their 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.

4.When can we respond to our mothers’ voices?

A.When we’re born. B.Before we’re born. C.When we grow up. D.When we’re young.

5.Where can we read the passage?

A.In a history book. B.In a fashion magazine. C.In a science magazine. D.In a morning newspaper.
