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 Mycobacterium．These 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 showers．Pace'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 health．Only those with a weak immune system might need to worry．He told the New York Times that the bacteria are not as unpleasant as might be thought．He 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.From the finding of Norman R. Pace, after taking a shower, we might cough or feel tired because .
| A．it’s easy to get a cold when taking a bath |
| B．the showerhead carries many bacteria causing illness |
| C．we don’t get cleaned while showering |

| B．Of 45 showerheads surveyed in nine cities, 30 carried large amounts of Mycobacterium. |
| C．Changing showerheads is the only way to avoid microorganisms. |

We can learn from the third paragraph that .
| A．having a shower in the morning is more dangerous than at other time |
| B．the bacteria always threat people’s health |
| C．there is no reason to fear microorganisms for people with strong immune system |
| D．it is better to do some exercise in the morning than have a shower |

| A．The train’s movement. | B．Iron particles． |

China news, Beijing, Feb. 9 – Housing price in China has always aroused heated discussions among property developers and ordinary Chinese. To many property developers and local government officials, housing price in China is still low compared with many developed countries. However, the average housing price in the United States is only 8,000 yuan per square meter, while in China, it is even higher than in the United States. This shows that there are some bubbles(泡沫) in Chinese real estate market, the International Finance News reported.
Although the average price of residential houses in the United States, after converted to Renminbi, is about 8,000 yuan per square meter, the houses in US are not sold in terms of building area, as most Chinese property developers do when they sell their houses. If US property developers sell their houses according to the building area, then the housing price will be even lower than 8,000 yuan per square meter. In most big Chinese cities, such as Beijing, Shanghai, and Shenzhen, houses are sold at a price even higher than those in the US.
The high housing sales price in large cities in China proves that Chinese real estate market does have some bubbles. Moreover, Chinese houses can not be compared with houses in US in terms of building quality, environment and supporting facilities. Furthermore, it should be noted that American people’s average income is several dozen times higher than that of Chinese people. How can the Chinese afford to buy a house which is even more expensive than that sold in US?
At the beginning of 2007, Chinese government issued a set of policies that aimed to benefit the public. Now in order to reduce the high housing prices, the government can regulate(控制) the real estate market by raising tax on property industry and controlling the release of loans and lands to property developers. At the same time, the government should allow people to build more houses through various fund-raising channels, such as funds collected from buyers or raised by working units. By applying these multiple means, it is expected that the high housing prices can be lowered.What is the average housing price per square meter in China?
| A．8000 yuan | B．10000 yuan |
| C．7000 yuan | D．It’s not mentioned here |
Which of the following does NOT support the idea that the average housing price in China
is even higher than in the United States?
| A．Chinese houses can not be compared with houses in US in terms of building quality, environment and supporting facilities. |
| B．American people’s average income is several dozen times higher than that of Chinese people. |
| C．The houses in US are not sold in terms of building area, as most Chinese property developers do when they sell their houses. |
| D．There are more people who need houses in China. |
What is the main idea of this passage?
A The housing price in China is so high that the government should do something useful to
prevent it.
B. There are some bubbles in Chinese real estate market
C. The average housing price in China is even higher than in the United States
D. Chinese government issued a set of policies that aimed to benefit the public.How many measures are mentioned in the last paragraph in order to reduce the high housing
prices?
| A．Four | B．Three | C．Five | D．Two |

John once told me a story about his friend, Michael. Michael happened to be on a train sitting next to a young man who seemed worried. Finally the young man told the friend that he was a convict (罪犯) returning home from a prison far away. What he did had brought shame (羞耻) on his family, and they had neither visited him nor written to him. He hoped, however, that this was only because they were too poor to travel and too busy to write.
When he was set free he had written to tell them he wanted to go home. To make matters easy for them, however, he had asked them to put up a signal (信号) for him when the train passed their little farm. If the family had forgiven (原谅) him, they were to put up a white ribbon (丝带) in the big apple tree near the railway.

I was small for my age. I was shy and sometimes it was hard for me to make friends with the others. However, learning came fairly easy for me. I was the best in most of my classes, but PE class was my nightmare (恶梦) and made me feel that I was not as good as the others.
Miss Forsythe was our PE teacher. She was young and energetic. Everyone liked her. She said that we all had to come to her classes. No one could hide from Miss Forsythe! One day she told me that she wanted me to play a game with another girl in a PE show. I was rather worried that I wouldn’t do a good job when she explained her idea, but she was excited. With her encouragement, I had no choice but to agree. It was a "boy meets girl" game. I played the boy and my classmate, Margaret Ann, played the girl. We were dressed in evening clothes and danced around the floor. According to Miss Forsythe, I had to pick up Margaret Ann when we finished the dance. Since I was not strong enough to pick the tallest girl up, it was she who picked me up. I suddenly felt ten feet tall! It was a huge success and everybody applauded (鼓掌) for our excellent performance. What a wonderful ending! Afterwards, I smiled confidently (自信地).
Miss Forsythe’s understanding and willingness to create a place for me in her show (which certainly did not need me) gave me some much needed confidence. She was and always will be my favorite teacher.What do we know about Miss Forsythe?
