information that has little to do with their work, according to a new survey.on average, whitecollar workers spend 51 percent of their work time receiving and processing information. only one third of it was relevant to their work, the survey found. information overload for whitecollar workers has become a global issue. the huge amount of information has already affected their efficiency in management as well as their performance at work.buried with emailsevery morning, a secretary at the human resources department of an auto parts company opens her email box, only to find it crammed with at least 50 unread mails.for her, even scanning through these emails every day takes at least half an hour. some of her colleagues are not so luckythey have to read at least 100.bothered with callstelephone calls are also causing a problem. more than 40 percent whitecollar workers choose mobile phones as the preferred way to communicate important and urgent business matters. talking saves time and energy over the clicking, reading and replying to emails, but phone calls are also more distracting(分心的). while answering a call, a clerk is likely to put away a much more important task at hand and start the business being talked about on the phone.solution? not yetmany companies start with providing staff with better computers, better internet access and more advanced gadgets(小装置). for example, staff members above a certain level in one company will be provided with a blackberry phone for easier access to their emails. the company has also organized many lectures on efficient ways of email management. yet most whitecollar workers think their companies can do more.11what does the new survey find about whitecollar workers?athey spend 51 percent of their work time on

overload.dbetter computers are in need in workplaces.bscientists who try to predict earthquakes have gotten some new helpers recentlyanimals.thats right, animals. scientists have begun to understand what farmers have known for thousands of years. animals often seem to know in advance that an earthquake is coming, and they show their fear by acting in strange ways. before a chinese quake in 1975, snakes awoke from their winter sleep early only to freeze to death in the cold air. cows broke their halters(缰绳) and tried to escape.chickens refused to enter their cage. all of this unusual behavior, as well as physical changes in the earth, warned chinese scientists of the coming quake. they moved people away from the danger zone and saved thousands of lives.one task for scientists today is to learn exactly which types of animal behavior predict quakes. its not an easy job. first of all, not every animal reacts to the danger of an earthquake. just before a california quake in 1977, for example, an arabian horse became very nervous and tried to break out of his enclosure. the australian horse next to him, however, remained perfectly calm. its also difficult at times to tell the difference between normal animal restlessness and “earthquake nerves”a zoo keeper once called earthquake researchers, saying that his cougar had been acting strangely. it turned out that the cat had an upset stomach.a second task for scientists is to find out exactly what kind of warnings the animals receive. they know that animals sense far more of the world than humans do. many animals can see, hear, and smell things that people do not even notice. some can sense tiny changes in air pressure, gravity, or the magnetism of the earth. this extra sense probably helps animals predict quakes.a good example of this occurred with a group of dogs. they were shut in an area that was being shaken by a series of tiny earthquakes.(several small quakes often come before or after a large one.) before each quake a low booming sound was heard. each boom caused the dogs to bark wildly. then the dogs began to bark during a silent period. a scientist who was recording quakes looked at his machine. it was acting as though there were a loud noise too. the scientist realized that the dogs had reacted to a booming noise. they also sensed the tiny quakes that followed it. the machine recorded both, though humans felt and heard nothing.in this case there was a machine to monitor what the dogs were sensing. many times, however, our machines record nothing extraordinary, even though animals know a quake is coming. the animals might be sensing something we measure but do not recognize as a warning.discovering what animals sense, and learning how they know it is a danger signal, is a job for future scientists.15through the passage the writer hopes to explore _awhy animals send a danger signal before an earthquakebhow animals know when an earthquake is comingcwhy animals not
