[单项选择]The 12-year-old boy who was rescued after spending 15 minutes or more in the cold Pacific likely survived because of his age, among other factors, experts say.
Charles Dale Ostrander was visiting the southwest Washington coast with his church youth group last Friday when he was swept out by a riptide. Rescuers who pulled him out said he had no pulse and his face was pale.
So how did he survive
Studies of near-drowning in cold water have found that survival depends on many factors including a person’s age, water temperature, time spent underwater and how fast CPR is given.
"He’s young and healthy," said Dr. Mark Morocco, an emergency room doctor at the Ronald Reagan UCLA Medical Center in Los Angeles. "Your chances of surviving are better if you’re young."
After people get over the initial shock of being plunged into cold water, they generally can survive for a certain period before getting exhausted or falling unconscious.

[单项选择]第三篇 Eat More,Weigh Less,Live Longer
Clever genetic detective work may have found out the reason why a near。starvation diet prolongs the life of many animals. ‘
Ronald Kahn at Harvard Medical School in Boston,US,and his colleagues have been able to extend the lifespan(寿命)of mice by 18 per cent by blocking the rodent’s(啮齿动物) increase of fat in specific cells.This suggests that thinness--and hot necessarily diet—-promotes long life in “ calerie (热量卡) restricted” animals.
“It’s very cool work.”says aging researcher Cynthia Kenyon of the University of California,San Francisco.“These mice eat all they want,lose weight and live longer.It’s like heaven.”
Calorie restriction dramatically extends the lifespan of organisms as different as worms and rodents.Whether this works in humans is still unknown,partly because few people are willing to submit to such a strict diet.

[单项选择]
Co-operation means working together for the benefit of all. Without co-operation modern society could not exist. Co-operation has at its best among the farmers in the dry areas of certain parts of Australia and Africa. The fields have been irrigated in these areas. Crops cannot be grown without water. For this purpose, canals and reservoirs have been built. The canals have been cut through the fields of not only one farmer. Those who live higher up the valley than the others have permitted canals to be built through their land in order to carry water to the fields of farmers lower down. When there is a long period without rain, all share the water. Instead of taking all the water for themselves, the farmers in the higher land leave enough water for their neighbours down the valley. Farming in the dry areas has been made possible by such co-operation. By co-operation farmers have learned to make even the desert produce crops.
