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.阅读填空Long ago, people believed that in the future we would work less, have more free time and get more relaxed. 20._Today we work harder, work longer hours and have more stresses than ten years ago.

On TV and the radio, newsreaders speak more quickly than ten years ago.In the USA，there is a book called OneMinute Bedtime Stories for children.These are shorter versions(版本)of traditional stories，specially written for “busy parents” who want to save time! Some answerphones now have “quick playback” buttons so that we can replay peoples messages fasterwe cant waste time listening to people speaking at the normal speed! 23._ Ten years ago when people went to art galleries they spent ten seconds looking at each picture. Today they spend just three seconds! Nowadays, many people prefer faster and dynamic sports like basketball.24_ Our cars are faster but the traffic is worse, so we drive more slowly.We spend more time sitting in our cars，feeling stressed.Experts predict that in ten years the average speed on the road in cities will be only 17 km/h.APeople felt stressed ten years ago.BBut unluckily，this has not happened yet.CEven when we relax we do everything more quickly.DBut what is this doing to our health?EFor most people，faster doesnt mean better.FThe only thing that is slower than before is the way we drive.GNow everything is faster than before，which brings us more convenience. 课时作业(十二).1.C考查动词辨析。句意：一个好老师应该留些时间让学生消化知识。digest消化；introduce介绍；receive收到；accept接受。2A考查短语辨析。before long意为“不久以后，很快”，通常用于将来时态的句子中作时间状语。long before意为“很久以前”或“在之前很长时间”，long是副词，而before既可作介词(后接名词或代词)、连词(后接句子)也可作副词(不接句子成分)，通常用于一般过去时的句子中。shortly after意为“之后不久”。very fast意为“很快”，主要指速度上的快。3A考查非谓语动词。此题中使役动词get后接的宾语car与作宾语补足语的动词wash之间为被动关系，构成短语：get sth done。故答案选A。句意：在驱车进城之前，你必须将你的车洗了。4B考查动词辨析。句意：如果我们想要获得成功，知识和学习很重要。但是它们或许会限制我们的思维。direct指示， 指引，导演(戏剧或电影)；指挥(管弦乐队)；limit限制；change改变；improve改进，改善。根据句中but的转折，选B。5A句意：我头痛得很厉害，我必须找个医生咨询一下。consult咨询，请教，商量。6A考查省略用法。在含有ought to句子的简略回答中， 表示过去动作的have不能省略。7C考查动词辨析。句意：如果他能把自己的才能和勤奋结合起来，必定会很成功。combinewith把和结合起来。8A考查固定搭配。on a diet 节食。9B考查动词短语辨析。get away with 逃脱惩罚。make use of 利用；get rid of 除掉；end up with 以而告终。10B考查动词短语辨析。throw away 扔掉； put away 收起来； give away 泄露(秘密)，捐献； carry away 拿走。11D考查动词短语辨析。cut down 削减。 cut up 切碎； cut off 切断；cut out 切除。12A句意：众所周知，迈克相当清楚他自己的优缺点。strength强项，长处，与weakness相对应。value价值；technique技术；energy精力，能量。13B考查形容词辨析。句意：你对她所做的事情感到满意吗？非常满意，她做得再好不过了。 not a little 非常，所以下文应是“她做得再好不过了”。 better 与 not 连用表示最高级含义。14Bhave sth to do 有某事要做； have sth done 让别人做某事。句意：即将到来的周末我有很多事要完成，因此我抽不出时间休息。故选B。15A句意：越来越多的中国人已经意识到他们应该均衡饮食，每天锻炼身体。diet是可数名词，表示泛指要用不定冠词a，go on a diet表示“节食”。do exercise锻炼身体，exercise前不用冠词。.白领是令人羡慕的一族，可是他们也有苦恼，与工作无关的海量信息让他们苦不堪言。16D细节理解题。根据Buried with emails中的最后一句可知一些白领每天要阅读至少100封电子邮件。17D推理判断题。Bothered with calls中的最后一句提到员工可能要放下更加重要的工作来处理电话事务，由此可推断打电话可能会导致工作程序的改变。18C细节理解题。根据文章最后一段前半部分中的内容可知一些公司解决问题的办法是为员工提供更加先进的设备。19C主旨大意题。本文是一篇调查报道，结合全文尤其是文章第一段的内容可知本文的主要内容是白领深受信息泛滥之苦。.20.
