1、(2011・广西桂林市、防城港市南京考越高三第一次联合调研考试) In the rush to get to school, you drop a piece of coast on the floor. Do you throw it away or decide it'

s still OK to et? 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 encodes 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 apiece of bread and a piece of bologna(一种大红肠)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.

(三)) How Do Animals Catch Their ZZZ'

s? ?????? Different creatures have developed some pretty creative ways to get their rest and stay safe. The lizard(蜥蝎)likes to sleep at the far end of small branches hanging out over a pond or lake in the rain forest. If a snake tries to slither up the branch to eat it, it will shake the branch and knock the lizard off , and the lizard will fall safely into the water. Chameleons (变色龙)can change color to match their surroundings in order to hide even while sleeping. ?????? Corillas(大猩猩)like to sleep high in the trees. They build a new bed every night, sometimes taking up to half an hour to pile branches, twigs, and leaves into a comfortable bed. Birds also find it safe to sleep in the trees, but unless they have eggs or young chicks, they don'

t use a nest. They just lock their feet around a branch and hang on. A special tendon(腱)in their legs is automatically tight when they are at rest, so they won'

t let go and fall. ???Dolphins(海豚) live underwater, but must come to the surface to breathe. Scientists now believe that dolphins may sleep with only half their brain, while the other half stays awake to keep them safe and breathing. Seals (海豹) also do this,lying on their sides on the surface of the water with one flipper underwater paddling to keep their noses above the surface. Some ducks may also have this ability, and actually sleep with one eye closed and one eye open.?(281 words) 60.How many animals are mentioned in this passage? ?????
