C

Researchers at Wake Forest University Medical Center did a research in monkeys and it could provide a clue (提示) about how the brain manages plenty of information and remembers what it needs. They found that when monkeys were taught to remember computer art pictures, their brains reduced the level of information by sorting the pictures into several kinds for recall, such as pictures that have to do with “people”，“buildings”，“flowers” and “animals”.

The brain sorting cells (細(xì)胞) were found in the hippocampus (海馬體) an area of the brain that processes sensory(感官) information into memory. It’s important for remembering all things including facts, places, or people. It might lead to some memory illness.

The researchers recorded the cell activity in the hippocampus while the monkeys were performing a memory task. Each monkey was shown one art picture, and after 30 seconds, picked it up from two to six different pictures to get a juice reward.

By recording cell activity during hundreds of these tasks, the researchers noticed that certain cells were more active when the pictures had the similar information, such as pictures of people but not other objects.

The researchers found that, however, that different monkeys sort the same pictures differently. For example, with a picture of a man in a blue coat, some monkeys placed it in the “people”，while others placed it in the “coat”.

“When you need to remember people you’ve just met at a meeting, the brain probably doesn’t memorize each person’s facial expressions,” says Sam, one of the researchers, “Instead, it records important information such as their hairstyle, height, or age, all parts that we are familiar with from meeting people in general. Our research suggests how the brain might do this, which could lead ways to improve memory in human. If we can understand how the brain works when decisions are made, we can predict when the brain will make a mistake, and correct it. This finding about how much information is processed by the brain will help us achieve that goal.”

There are many colours in nature. But do you know that a colour has weight? I think you'll say“no”. But I am afraid you are wrong. If you don't believe, you may do a small experiment（實(shí)驗(yàn)）.

First, put two objects with the same weight into two boxes. Then cover the boxes. Wrap（包裹） one box with a red piece of paper, the other with a white piece of paper. Now hold the boxes with your hand one by one. It is certain that you will think the red one is a lttle heavier.

Why does it happen? A scientist found that different colours have different weight in a man's mind. So he did many tests and at last he got the result. That is to say, every colour has its .own weight in our mind. The heaviest colour is red, then blue, green, orange, yellow an.d white. The scientists told us that colours also have smell. Can you smell the colour? Of course not. Then why did the scientists say so? That is because every colour represents a kind of light wave（光波）— a certain wavelength（波長(zhǎng)）. It reaches our brain（大腦） through organs（感覺器官）

According to this discovery, scientists say that people accept the colour they like, and refuse the colour they hate. So your body and mind will be healthy by using the colours you like. Or you'll be nervous or even get ill. If you stay in a room with red windows, wallpapers and furniture for two hours, you'll feel you have been there for four hours. But if the room is blue, you'll feel you have been there for only one hour. Another example, if a person walks out of a red room and into a blue room, his temperature will fall. That means our body temperature will change when we see different colours.

1.Which is the lightest colour in a man's mind?

A.Red B.Blue C.Green D.White

2.Which of the following is NOT true?

A.Different colors have different weights in a man's mind.

B.The colours “blue” is the second heaviest colour in a man's mind.

C.People can't smell the colours.

D.The colour you don't like will keep you healthy.

3.According to the passage, how long will you feel if you stay in a red room for an hour?

A.Two hours. B.Fours hours C.Six hours D.Eight hours.
