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!

TAIPEI, Taiwan―Facing its worst drought in decades, Taiwan is buying water from the mainland of China   21  since the two rivals split amid civil war 54 years ago.

A Taiwanese ship on Sunday was expected   22  2,300 metric tons (2,530 short tons) of water back from the mainland of China to Taiwan’s outlying island of Matsu, just off China’s southeastern coast.

Buying water from the mainland of China has been an issue of serious debate in Taiwan because the government does not want to become too   23  its communist neighbor, which has repeatedly said to   24  Taiwan.

But the serious drought has left Taiwan   25  ,and Taiwan’s top China policy―maker, Tsai Ingwen, said on Saturday that this weekend’s water purchase would be a “trial run,” the semiofficial Central News Agency   26  .

  27  it will become a model for easing needs in drought―stricken Taiwan depends on the needs of other areas,” Tsai, chairwoman of the Mainland Affairs Council, was quoted as saying.

There are no direct   28  air links between the mainland of China and Taiwan’s main island, separated by   29  160―kilometer―wide  Taiwan Strait. But last year, Taiwan opened shipping links between the mainland of China and the outlying Taiwanese islands of Kinmen and Matsu―an experiment   30  links between the mainland of China of Taiwan’s main island.

     Erik became an adventurer. He took up parachuting, wrestling and scuba diving. He competed in
long-distance biking, marathons and skiing. His favorite sport, though, is mountaineering.
     As a young man, Erik started to climb mountains. He reached the summit of Mount McKinley in
1995 and then climbed the dangerous 1000-metre rock wall of EI Capitan. Two years later, while

sea level-in order to get married. In 1999, he climbed Aconcagua, the tallest mountain in South
America.And then, on May 25, 2001, at the age of 33, Erik successfully completed the greatest
mountaineering challenge of all. He climbed Mount Everest, the highest mountain in the world.
     Erik invented his own method for climbing mountains. He carries two long poles: one to lean on
and the other to test the way ahead of him. The climber in front of him wears a bell to gu ide him.
Erik is a good team member. He does his share of the job, such as setting up tents and building
snow walls.
      Although he could not enjoy the view, Erik felt the excitement of being on the summit of Everest.
