It was a cold winter morning. Half asleep at the train station, I stared into the distance,   36   for the train to take me to my   37   in Boston. The word was quiet. The very few people on the street kept to themselves,   38   their steaming cups of coffee.
Reaching into my pocket as the   39 was approaching, my numb hand searched for the $ 20 bill to pay my fare. The pocket was   40 ! I searched through my bag and then I felt   41 . Unless the money dropped from the sky, I’d be   42   there.
“What’s the matter?” A short, elderly man stood before me.
“Oh, nothing…. Well, I   43   my money and now I can’t pay for the ticket. I’m going to   44   my match class, and the train is leaving.”
“Here, use this.”
The man held a $ 20 bill. I looked up,   45 . People just didn’t do that anymore. Everyone worried about their own   46 , rarely stopping to think about others, especially teenage strangers.
“Thank you, but no, I can’t.”
“ 47 it – go!” The man pushed me   48   the train. I bought a round – trip ticket, and he refused the change I   49 to give him back. I did not know what to say – a million thoughts raced through my mind, yet I stood   50 .
For the train ride I was silent. I began to see the world through   51 eyes. That man made a difference with such a simple   52 .
A week later I was at the train station again, with an extra $ 20   53 I saw the man. And there he was.
“excuse me, sir, I believe I owe you this.” I   54 the money into his hand.
Failing to refuse, he said, “Just remember to do the same for someone in your shoes someday.” I smiled, content.
The elderly man is my hero. For many, heroes are famous, but my hero is a   55 stranger who taught me a lesson in life. I will never forget his kindness.

Zhoukoudian is a small village situated about 50 kilometers to the southwest of Beijing. In the 1920s, archaeologists discovered some prehistoric human bones there which changed people’s view of China’s history. They came from an unknown species of man and were the first evidence of human life in China thousands of years ago. The remains were three teeth!
In 1929, a complete skull was also discovered. Eventually, archaeologist found almost 200 items, including six skulls and more than 150 teeth. These discoveries proved the existence of a human species who lived in the area between 700,000 and 200,000 years ago. Four sites where Beijing Man and his relatives lived were discovered on the northern face of Longgushan. They lived in the caves in the area.
However, the life span of Beijing Man was short. About 70% of the peole probably died before the age of 14. Fewer than 5% lived to the age of 50. Ashes were found alongside the fossils which showed they had used fire for cooking food and also for light, warmth, and protection against wild animals. This is the earliest evidence of the use of fire anywhere in the world. They also made tools of bones and stones. Unfortunately, when Japan invaded（侵略） China in 1937, excavations（挖掘） at the Beijing Man Site stopped and most of the fossils disappeared, including a Beijing Man skull. After the People’s Republic of China was established in 1949, the work started again.
Zhoukoudian was listed as a World Heritage Site in December 1987. It has not only given us important information about prehistoric Asian societies, but also provided amazing evidence about the process of evolution. Today, parts of the caves have been badly affected by rain. Some areas are almost completely covered in weeds, causing serious damage. Pollution from the nearby factories has also contributed to the problem. This is a very serious matter and the Chinese Academy of Sciences is trying to raise public awareness of it.

What’s that smell? Do you hear that noise? Taste this! Look at me! Feel this, isn’t it soft? When you hear, or even use these phrases, you probably don’t stop to think about why we use them. Well, it’s because of our senses. Without us even knowing, our sense organs (nose, eyes, ears, tongue, and skin) are taking in information and sending it to the brain for processing. If we didn’t have them, we would not be able to smell, see, hear, taste, or touch anything!
Senses are the physical means by which all living things see, hear, smell, taste, and touch. Each sense collects information about the world and detects changes within the body. Both people and animals get all of their knowledge from their senses, and that is why senses are so important.
All senses depend on the working nerve system. Our sense organs start to work when something stimulates（刺激） special nerve cells, called receptors, in a sense organ. Once stimulated, the receptors send nerve impulses along sensory nerves to the brain. Your brain then tells you what to do. For example, your sound receptors are often attacked by billions of sound waves. When these signals reach the part of the brain called the cerebral cortex（大脑皮层）, we become conscious of the sounds.
Our group really learned a lot about the senses while creating this website. We hope that you are able to get just as much out of it. Please feel free to comment about anything on the site by e-mailing us. Also, don’t forget to sign the guest book! Thanks for visiting our site. Come back soon!

Have you ever intended to be fully absorbed in your work but found yourself distracted by e-mail, the Internet and other things throughout the day? According to the survey made by a famous university in the USA, most people have the experience.
"People often lose their concentration when they are bored, of course, but also when they are engaged in challenging tasks," says Peter Bregman, the head of the survey. "They sometimes have a feeling to escape from what's difficult or boring, so they jump out," he says. The part of the brain devoted to attention is connected to the brain's emotional center. Any strong emotion —quarrels with colleagues, problems at home —can interrupt our attention. Studies over the last decade have shown that too much work to do at a time can easily lead to distraction.
Refocusing is hard for many people. Robert Epstein suggests the following, "Stop and listen to some soft music for a few minutes. Find a good friend or a teacher and say out your matter on your mind. Go for a short walk or take a deep breath, where you breathe in deeply, count to five slowly, hold it and breathe out very slowly." This can "blow out all the tension and the unwanted in your mind to restore your focus."
Take more control by structuring your time and becoming more aware of your behaviors. "Setting the phone alarm to go off every hour is my way of creating awareness," Mr. Bregman says. "You have to inform yourself that you've lost focus in order to do something about it." Starting the day with a to-do list is also important, such as when to eat, when to go to the gym or take a walk. But if it's overly ambitious, you will put yourself in a state of anxiety, which makes it hard for the brain to concentrate. "Choosing three or four things as your priority for the day allows your brain to settle down and focus," he says.

When a dirty and untidy orange cat showed up in the prison yard，I was one of the first to go out there and pet it．I hadn’t touched a cat or a dog in over 20 years．I spent at least 20 minutes，knelt down behind the kitchen as the cat rolled around，relaxed．What he was expressing outwardly, I was feeling inwardly．It was an amazing bit of grace to feel him under my hand and note that I was reaching a life or another creature with something as simple as my care．
Over the next few days，there were other prisoners responding to the cat．Every yard period，a group of prisoners gathered there．They stood around talking and taking turns petting the cat．These were guys you wouldn’t usually find talking to each other．Several times I saw an officer in the group，not chasing people away, but just watching and seeming to enjoy along with the prisoners．Bowls of milk and water appeared along with bread, wisely placed under the edge of the dustbin to keep the birds from getting it．
The cat was obviously homeless and in pretty bad shape．People said that the cat came to the right place．He's getting treated like a king．This was true．but as I watched I was also thinking about what the cat was doing for us．There was a lot of talk about what's wrong with prisons in America．We need more programs．We need more psychologists or treatment of various kinds．Some may even talk about making prisons more kind．But I think what we really need is a chance to practise our own kindness．Not receive it，but give it．After more than two decades here，I know kindness is not a value that's encouraged．It's often seen as a weakness．
Instead，the culture encourages keeping your head down，minding your own business，and never letting yourself be weak．
The cat did my heart good to see the effect he had on me and the men here．By simply saying，”I need some help here”，he did something important for us．He needed us．And we needed to be needed．I believe we all do．
