Everything that humans hear is in the form of waves (波).Just as the eye sees light wares in the form of colors, the ear and the eye Curs these different waves into signals that the brain (大脑) can make sense of.
The ears and brain have an Amazing amities 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 is 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.
After 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.Which of the following shows the normal hearing process of a mother hearing her baby crying?

Who would win in a competition to memorize numbers, a chimp (黑猩猩) or a teenager? The teenager? Think again. Scientists have proved that chimps perform better than human beings when it comes to this kind of problem. We may have to rethink what we believe about human memory.
Memory is our ability to learn something, save it and recall it when needed. Our memories are important to our sense of self, our personalities, and our ability to understand the world.
Scientists say that there are different types of memory. There is short-term memory and long-term memory. Your short-term memory saves information for a few seconds or a few minutes. For example, the time it takes to compare the prices of a few items in a store. Long-term memory involves the information you try hard to keep, because it’s meaningful to you (an example is data 数据 about family and friends. ) And then there is visual memory and sound memory. But these are not hard and fast: scientists argue a lot about the nature of memory.
Scientists have also found that people memorize things in different ways. Some memorize better with the help of pictures. Others are helped more by sounds. One thing’s for sure. If you can combine different kinds of memory together, you will remember a lot! So why not try pictures with English words? At the same time listen to recordings of the same group of words. It may help when it comes to memorizing it.
Imagination and association can be useful too. By imagination scientists mean picturing a word in your mind. Association means relating the word to something you already know.What can we learn from Paragraph 1?

Bai Yansong, a famous TV host, expressed his support for students wearing green scarves (绿领巾) at a primary school in Xi’an. He wore a green tie on a TV program on October 19, 2011. “I just want the students to know that I’m also wearing green. And we are all great people and are as good as those wearing red scarves.”
The First Experimental Primary School in Xi’an made children with poor schoolwork and behavior wear green scarves. Parents whose children wore green scarves were angry. “The children still need their self-esteem (自尊心) even though they are very young, and they know the green scarf means something is not quite right,” said one mother. Now, the school has stopped the practice.
Educational expert Li Zhenxi said that primary and junior high school students have strong self-esteem. They are eager to be respected and understood. Punishment will hurt them. “It’s better to encourage them rather than separating some ‘bad’ students,” he said.
A survey made by the Ministry of Education (教育部) shows that 75 percent of students feel nervous and scared when the teacher is about to announce their grades. Some schools have done better in protecting students’ privacy and encouraging them. In American schools, teachers post test results on the wall. Instead of using student names, they use secret numbers. This way, students know their secret numbers and can check their own grades only. Some teachers might call the students up to the desk and tell them their scores one at a time.
But test scores are not the only measures of a student’s ability. Everyone has his own strengths and everyone can make great progress by working hard.Bai Yansong wore a green tie in a TV program in order to _______.

According to the article, which of the following is TRUE?
| A．Primary school students are too young to know what self-esteem is. |
| B．Separating some “bad” students helps create good learning environment. |
| C．Most “good” students like their teachers to announce their scores. |

One Sunday afternoon, I went shopping at Wal-Mart . But I never thought I would have a life changing experience at WalMart.
Although my thoughts were only on speed, the checkout line I was standing in wasn’t moving as quickly as I wanted, and I looked towards the cashier.
There stood a man in his seventies, wearing glasses and a nice smile. I thought, well, he’s an old guy!
For the next few minutes I watched him. He greeted every customerbefore scanning the items. Sure,his words were the usual, “How’s it going？” But he did something different—he listened to people carefully and then he would reply to what they had said
I thought it was strange. I has grown used to people asking me how I was doing simply out of conversational habit. I could say, “I just found out I have six months to live，” and someone would reply, “Have a great day！”
But that wasn't the end.
He gave them the change, walked around the counter (柜台), and hugged them with his right hand in an act of friendship. He lookedatthe customersin the eyes. “I want to thank you for shopping here today,” he told them. “You have a great day. Bye-bye.”
The smiling looks on the faces of the customers were priceless. All had been touched by his simple gesture—and in a place they never expected. They would gather their things and walk out, smiling.
Of course, he did the same to me and I got to know his name—Marty.
Who was that guy? It was as if Sam Walton(沃尔玛的创始人)had come back from the dead and invaded this old guy’s body.
I had never walked away from that shop feeling like that.
