Generations of Americans have been
brought up to believe that a good breakfast is one of life’ s essentials.
Eating breakfast at the start of the day, we have all been told, is as
necessary as putting gasoline in the family car before starting a
trip. But for many people the thought that food is the first thing you have, in the morning is by no means a pleasure. So despite all the efforts, they still take no breakfast. Between 1977 and 1983, the latest years for which figures are available, the number of people who didn’ t have breakfast increased by 33 percent—from 8.8 million to 11.7 million—according to the Chicago-based Market Research Corporation of America. For those who feel pain or guilt (内疚) about not eating breakfast, however, there is some good news. Several studies in the last few years indicate that, for adults especiall A. a study of the Chicago-based Market Research Corporation B. one of life’ s essentials C. latest figures of people who don’t eat breakfast D. breakfast and human health [单项选择]An accidental discovery has brought seismologists(地震学家) one step closer to being able to predict earthquakes. As part of an unrelated effort to measure underground changes caused by shifts in barometric pressure (大气压力), a team of researchers found that increases in subterranean pressure(地下压力) preceded earthquakes along California’s San Andreas Fault(断层) by as much as 10 hours. If follow-up tests advance the findings, seismologists may eventually be able to provide a few hours’ notice for people to find safe places prior to quakes.
Researchers used a high-tech equivalent of a stereo speaker lowered into a bore hole near Parkfield, Calif., a half-mile deep and five yards from a measuring device. For two months beginning in late 2005, researchers transmitted pulse signals three times per second, from the speaker to the measuring device, calculating travel time between the two stations. Surprised scientists learned the seismic waves slowed dramatically on only two occasions: two hou A. the importance of predicting earthquakes B. a new method to predict earthquakes C. the great damages caused by earthquakes D. a traditional method to predict earthquakes [单项选择]Who has been there
