Judging from recent surveys, most experts in sleep behavior agree that there is virtually an epidemic of sleepiness in the nation. "I can’t think of a single study that hasn’t found Americans getting less sleep than they ought to," says Dr David. Even people who think they are sleeping enough would probably be better off with more rest.
The beginning of our sleep-deficit crisis can be traced to the invention of the light bulb a century ago. From diary entries and other personal accounts from the 18th and 19th centuries, sleep scientists have reached the conclusion that the average person used to sleep about 9.5 hours a night. "The best sleep habits once were forced on us, when we had nothing to do in the evening down on the farm, and it was dark. " By the 1950s and 1960s, that sleep schedule had been reduced dramatically, to between 7.5 and 8 hours, and most people had to wake to an alarm clock. "People cheat on their sleep, and they d

Water on the earth is being continuously recycled in a process known as the hydrologic cycle. The first step of the cycle is the evaporation of water in the oceans. Evaporation is the process of water turning into vapor, which then forms clouds in the sky. The second step is the water returning to the earth in the form of precipitation, either rain, snow, or ice. When the water reaches the earth’s surface, it runs off into the rivers, lakes, and the ocean, where the cycle begins again.
Not all water, however, stays on the surface of the earth in the hydrologic cycle. Some of it seeps (渗透) into the ground through infiltration and collects under the earth’s surface as groundwater. This groundwater is extremely important to life on earth since 95% of the earth’s water is in the oceans, and is too salty for humans of plants. Of the 5% on land, only 0.05% is above ground in rivers or lakes. The rest is underground water. This groundwater is plentiful
A. water vapor
