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(小裝置). 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.閱讀填空根據(jù)短文內(nèi)容，從短文后的七個(gè)選項(xiàng)中選出能填入空白處的最佳選項(xiàng)。選項(xiàng)中有兩項(xiàng)為多余選項(xiàng)。When it comes to the world of computers, green computing is becoming one of the most popular trends. _20_The term “green computing” is one that is being used in many different markets and areas all over the world in today's global technology.Green computing is basically learning to use computer resources more efficiently to help the environment as well as making energy savings. _21_Green computing started as early as 1992, when the EPA created Energy Star, which is a voluntary labeling program that promotes energy­efficient computing equipment and technologies. It was because of this program that many computer companies launched sleep mode(模式) and millions of computer users around the world began to adopt this policy to help save energy when they were not using their computers._22_ It also began to become a goal that more companies try hard to meet over the years. There are several government agencies that have continued to work for better standards to promote green computing. _23_ Because of these new requirements, there are over 20 states that have now established a special recycling program for old computers and electronics to help with green computing.Many of today's IT systems are beginning to rely on both people and hardware to help push their computer system toward a more green computing system to help both the company and others. This is a hard balance to achieve, as it has to satisfy both users and management. _24_ Many companies are learning the best way of green computing in their business process. While many home computer users may not be quite as familiar with green computing as large firms, this term is starting to become more mainstream all around the world and the requirements for new, better computers to help both the companies and the end users of the equipment, as well as our environment, are becoming more and more urgent.AIt also worked out a ranking system for products.BThe main goal of a green computing program is to reduce the use of energy and materials that harm the environment.CBut, what is exactly green computing?DGreen computing also helps to promote the use of biodegradable products and recycle computer parts whenever possible.EEnergy Star was actually revised in 2006 to make the requirements stricter for computers.FEven the disposal of computer waste is all managed so that everyone in the circle is happy with the outcome.GAround the same time the term “green computing” began to be used as well.參考答案課時(shí)作業(yè)(十二).1.C考查動(dòng)詞辨析。句意：一個(gè)好老師應(yīng)該留些時(shí)間讓學(xué)生消化知識。digest消化；introduce介紹；receive收到；accept接受。2A考查短語辨析。before long意為“不久以后，很快”，通常用于將來時(shí)態(tài)的句子中作時(shí)間狀語。long before意為“很久以前”或“在之前很長時(shí)間”，long是副詞，而before既可作介詞(后接名詞或代詞)、連詞(后接句子)也可作副詞(不接句子成分)，通常用于一般過去時(shí)的句子中。shortly after意為“之后不久”。very fast意為“很快”，主要指速度上的快。3A考查非謂語動(dòng)詞。此題中使役動(dòng)詞get后接的賓語car與作賓語補(bǔ)足語的動(dòng)詞wash之間為被動(dòng)關(guān)系，構(gòu)成短語：get sth done。故答案選A。句意：在驅(qū)車進(jìn)城之前，你必須將你的車洗了。4B考查動(dòng)詞辨析。句意：如果我們想要獲得成功，知識和學(xué)習(xí)很重要。但是它們或許會限制我們的思維。direct指示， 指引，導(dǎo)演(戲劇或電影)；指揮(管弦樂隊(duì))；limit限制；change改變；improve改進(jìn)，改善。根據(jù)句中but的轉(zhuǎn)折，選B。5A句意：我頭痛得很厲害，我必須找個(gè)醫(yī)生咨詢一下。consult咨詢，請教，商量。6A考查省略用法。在含有ought to句子的簡略回答中， 表示過去動(dòng)作的have不能省略。7C考查動(dòng)詞辨析。句意：如果他能把自己的才能和勤奮結(jié)合起來，必定會很成功。combinewith把和結(jié)合起來。8A考查固定搭配。on a diet 節(jié)食。9B考查動(dòng)詞短語辨析。get away with 逃脫懲罰。make use of 利用；get rid of 除掉；end up with 以而告終。10B考查動(dòng)詞短語辨析。throw away 扔掉； put away 收起來； give away 泄露(秘密)，捐獻(xiàn)； carry away 拿走。11D考查動(dòng)詞短語辨析。cut down 削減。 cut up 切碎； cut off 切斷；cut out 切除。12A句意：眾所周知，邁克相當(dāng)清楚他自己的優(yōu)缺點(diǎn)。strength強(qiáng)項(xiàng)，長處，與weakness相對應(yīng)。value價(jià)值；technique技術(shù)；energy精力，能量。13B考查形容詞辨析。句意：你對她所做的事情感到滿意嗎？非常滿意，她做得再好不過了。 not a little 非常，所以下文應(yīng)是“她做得再好不過了”。 better 與 not 連用表示最高級含義。14Bhave sth to do 有某事要做； have sth done 讓別人做某事。句意：即將到來的周末我有很多事要完成，因此我抽不出時(shí)間休息。故選B。15A句意：越來越多的中國人已經(jīng)意識到他們應(yīng)該均衡飲食，每天鍛煉身體。diet是可數(shù)名詞，表示泛指要用不定冠詞a，go on a diet表示“節(jié)食”。do exercise鍛煉身體，exercise前不用冠詞。.白領(lǐng)是令人羨慕的一族，可是他們也有苦惱，與工作無關(guān)的海量信息讓他們苦不堪言。16D細(xì)節(jié)理解題。根據(jù)Buried with e­mails中的最后一句可知一些白領(lǐng)每天要閱讀至少100封電子郵件。17D推理判斷題。Bothered with calls中的最后一句提到員工可能要放下更加重要的工作來處理電話事務(wù)，由此可推斷打電話可能會導(dǎo)致工作程序的改變。18C細(xì)節(jié)理解題。根據(jù)文章最后一段前半部分中的內(nèi)容可知一些公司解決問題的辦法是為員工提供更加先進(jìn)的設(shè)備。19C主旨大意題。本文是一篇調(diào)查報(bào)道，結(jié)合全文尤其是文章第一段的內(nèi)容可知本文的主要內(nèi)容是白領(lǐng)深受信息泛濫之苦。.2024CBGEF
