On a Friday night, a poor young artist stood at the gate of the New York railway station, playing his violin. The music was so great that many people stopped to put some money into the hat of the young man.
The next day, the young artist came to the same place, and put his hat on the ground gracefully. Different from the day before, he took out a large piece of paper and laid it under his hat. Then he began to play the violin. It sounded more pleasant than ever.
Soon he was surrounded with people who were attracted by the words on that paper. It said, “Last night, a gentleman named George Sang put an important thing into my hat by mistake. Please come to claim(认领) it soon.”
After about half an hour, a middle-aged man rushed through the crowd to the violinist and said, “Yes, it’s you. I knew that you were an honest man and would certainly come here.” The young violinist asked calmly, “Are you Mr. George Sang?” The man nodded. The violinist asked, “Did you lose something?” “It’s a lottery ticket,” said the man. The violinist took out a lottery ticket on which George Sang’s name was seen. “Is it?” he asked. George nodded and took the lottery ticket and kissed it, then danced with the violinist.
The violinist was a student at an arts college and had planned to attend advanced studies in Vienna. Later his classmate asked the violinist, “At that time you needed money to pay the tuition(学费) and you had to play the violin in the railway station every day to make money. Why didn’t you keep the lottery ticket for yourself?” The violinist said, “Although I don’t have much money, I live happily. But if I lose honesty I won’t be happy forever.”
Through our lives, we can gain a lot and lose so much. But being honest should always be with us.

It is generally believed that we are getting cleaned when we step under a shower. We are, but we’re also giving a home to lots of tiny little creatures we didn’t even know about. A showerhead carries thousands of bacteria called MycobacteriumThese can cause problems like coughs and tiredness, and a general feeling of poorliness (身体不舒服). When you turn on the water, the bacteria go from the showerhead onto and into your body.

??? This is a finding of Norman R. Pace and his team at the University of Colorado, in the US. The scientists investigated bacteria in all kinds of human environment, including showersPace's team looked at 45 showerheads in nine American cities. They discovered that 30 percent of them had large amounts of flying Mycobacterium.

But Pace said that they pose few threats to the healthOnly those with a weak immune system might need to worryHe told the New York Times that the bacteria are not as unpleasant as might be thoughtHe said that having a shower is no more dangerous than anything else we do in the morning

But for those who feel sick about the idea of all those microorganisms (微生物), he had some advice. Let the water run for 30 seconds before getting into the shower. Why? The number of bacteria is smaller than that when the water is just turned on. If that seems like a waste of water, he added that you could also change your showerhead every few months.

??? However, Pace had good news too. He has also been testing the air in US subways. Apart from iron particles (粒子), which are ground off the track by the wheels of trains, subway air is fresh. The reason is that a train’s movement pumps fresh outdoor air into the tunnels.

??? Pace explained that he wanted to understand the natural microbial environments of public places. This kind of knowledge might help discover the microbes to be used in a bioterrorist (生物恐怖分子) attack.

The first bullet "train designed and manufactured in China with a speed of 300 kilometers per hour roiled off the production line on Saturday morning. The train was the latest model in the country' s China Railway High-speed (CRH) Series. This marks that China has joined a leading world club after Japan, France and Germany to become the fourth country capable of turning out such high speed trains. Previously, China' s fastest selfdeveloped trains ran at a service speed of up to 250 km per hour.
Those trains, which presented to public on April 18, served the Beijing-Harbin, Beijing-Shanghai and Beijing-Guangzhou routes. The new streamlined train was made of aluminum alloy(铝合金). The train body was the lightest of its kind in the world; Such a design was for the sake of energy economization. The train' s power was 12.7 kilowatts, lower than other high-speed trains, which was normally about 15 kilowatts.
The new train, which features a bar in the dining car and double-faced LCD TV screens in the first-class cars, was equipped with shock absorbers between carriages. As the train is running at a high speed, the shock absorbers are used to reduce shocking force and rocking of the train body. A train with eight carriages could seat about 600 passengers. They were expected to run on the 115-km Beijing-Tianjin route starting from August before the Beijing Olympic Games. It would reduce the journey time from the current 80 minutes to around 30 minutes.
