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.16What does the new survey find about whitecollar workers?AThey spend 51 percent of their work time on meetings.BOnly half of the information they receive is useful.COver 60 percent of them prefer to use the telephone.DSome of them have to read at least 100 emails every day.17Telephone calls cause a problem because _Athey take up the time to receive and send emailsBthey are often not answeredCthey are mostly not about businessDthey may lead to change of work schedule18How do some companies try to solve the problem of information overload?AThey start to give staff a pay rise.BThey plan to employ more people.CThey provide employees with more advanced equipment.DThey organize lectures on how to reduce stress.19What is the major issue discussed in this text?APoor management leads to inefficiency at work.BJunk mail is causing big trouble.CWhitecollar workers suffer from information overload.DBetter computers are in need in workplaces.B
