You may not be aware, but digital currency (货币) is a big part of the Internet world. QQ Coins can buy you accessories (配饰) for your QQ images. More importantly, a new digital currency, Bitcoin, is bringing the world’s commerce online.
If you’re traveling, you can spend Bitcoins at restaurants and hotels listed at BitcoinTravel.com. In China, Bitcoins can be used to buy goods at about 134 online shops on Taobao. And at a café named 2nd Place in Beijing, you can even buy fresh coffee with Bitcoins.
So what makes Bitcoin so attractive to investors?
First of all, the Bitcoin system is not controlled by anyone. One central authority cannot make policies to change the value of Bitcoins. The fixed amount of Bitcoins also means they cannot lose value through inflation(通货膨胀), as all forms of paper money have done over time.
In addition, accounts in the Bitcoin system are anonymous and transparent. Users can set up an account easily and track every Bitcoin. All of these features seem to make Bitcoins immune(有免疫力的) from loss, but that is not entirely true.
“The value of Bitcoins can vary wildly as no central government makes the price of them steady. If the value drops suddenly, investors cannot get any compensation(赔偿),” Zhao Qingming, a senior researcher at China Construction Bank, told China Economic Weekly. And Bitcoins, unlike company shares, are not backed by any tangible funds, which also adds to their risk.
While China will not recognize the digital currency anytime soon, Xinhua said, lawmakers and officials at a hearing on Nov. 18 in the US made positive comments about Bitcoin.
Ben Bernanke, outgoing chairman of the Federal Reserve, told the Washington Post that “these types of creations, such as Bitcoin… may hold long-term promise, particularly if its system promote a faster, more secure and more efficient payment system.”Bitcoin is ______.
A. actually exactly like QQ Coins

| A．online goods |

What is the disadvantage of Bitcoin?
| A．the value of it can rise and fall wildly. |
| B．It cannot lose value through inflation. |
| C．Every bitcoin in your account can be followed. |
| D．It can even be used at some specific restaurants and hotels. |

In the rush to get to school, you drop a piece of toast on the floor. Do you throw it away or dec ide it’ s still OK to eat? If you’re like most people, you eat it. Maybe you follow the “5-second rule”, which claims foods are safe to eat if you pick them up within 5 seconds after dropping them. But you might want to think again. Scientists now say that 5 seconds is all it takes for foods to become polluted with enough bacteria（细菌） to make you sick.
Bacteria can cause many kinds of illnesses. Some kinds of bacteria can grow on food. If you eat foods on which these bacteria are growing, you can become sick.
One of these food-borne bacteria is Salmonella. It makes 1.4 million people sick every year. Salmonella is often found in raw eggs and chicken. Cooking kills these bacteria, which is why it is so important to cook eggs, chicken, and other foods thoroughly.
But how long does it take these bacteria to pollute food? A team of scientists in South Carolina did an experiment. First, they placed an amount of Salmonella on three surfaces; wood, tile (瓦片), and carpet. They placed a piece of bread and a piece of bologna（大腊肠） on each surface for 5,30, or 60 seconds. After just 5 seconds, both the bread and the bologna picked up enough bacteria to make you sick.
So forget the 5-second rule. If your toast drops on the floor, throw it away and get another piece of clean toast. This time, be careful not to drop it! In which part of a newspaper can you most probably find this passage?
| A．Culture | B．Health | C．Advertisement | D．Technology |
After dropping a piece of toast , a person who follows the “5-second rule”will
| A．throw away dirty toast immediately and go away |
| B．pick up the toast as quickly as possible and eat it |
| C．eat the toast within 5 seconds and feel pleased |
| D．get another piece of clean toast quickly and eat it |
The scientists in South Carolina did the experiment to
| A．see how quickly bacteria can pollute food |
| B．show that the 5-second rule a correct |
| C．see how harmful bacteria are to people’ health |
| D．show that bacteria grow at different speeds on different foods |
What’s the writer’s attitude to the “5-second rule”?
| A．Positive | B．Negative | C．Neutral (中立) | D．Cautious (谨慎) |
