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 (细胞) were found in the hippocampus (海马体) 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.”

Americans use many expressions with the word dog. Dogs without owners to care for them lead to a different kind of life. The expression, to lead a dog’s life, describes a person who has an unhappy life.

Some people say we live in a dog-eat-dog world. ___________ Only those who are capable will have the chance to work in the best company. They say that to be successful, a person has to work like a dog. This means they have to work very, very hard to meet the standards of your strict boss. Such hard work can make people dog-tired, which means no matter how noisy it is, tired people can enjoy a sound sleep like a sleepy dog. ________ If so, they will have no energy to work at all.

Still, people say every dog has its day. This means that every person enjoys a successful period during his or her life. To be successful, people often have to learn new skills. Yet, some people say that you can never teach an old dog new tricks. ___________ So never try to teach your grandfather at the age of 90 to use a smart phone.

Sometimes, people say love me, love my dog. It means if you love anyone, you will like all that belongs to him, including his weakness and mistakes.

___________ For example, a woman might get mad at her husband for coming home late or forgetting their wedding anniversary. She might tell him that he is in the doghouse. She may not treat him nicely until he says sorry.

___________ The dog days of summer are the hottest days of the year. A rainstorm may cool the weather. But we do not want it to rain too hard. We do not want it to rain cats and dogs. Because we are going to get soaked in the heavy rain.

A. They believe old people aren’t willing to learn new things and change their ways.

B. And, the situation would be even worse if they became sick as a dog.

C. They take their dogs for a walk on sunny days and dress them beautifully.

D. Husbands and wives use this doghouse term when they are angry at each other.

E. That means many people are competing for the same things, like good jobs.
