Unit 2 Cloning李仕才一、閱讀理解。In many developed countries, people who have high degrees begin to work longer than those who dont. About 65% of American men aged 6274 with a professional degree are in the workforce(勞動人口), compared with 32% of men who only finish high school. This gap is part of a deepening divide between the welleducated wealthy and the unskilled poor. Rapid technological advance has raised the incomes of the highly skilled while squeezing those of the unskilled. The consequences, for individuals and society, are profound.The world is facing an astonishing rise in the number of old people, and they will live longer than ever before. Over the next 20 years the global population of those aged 65 or more will almost double, from 600 million to 1.1 billion. The experience of the 20th century, when greater longevity(長壽) translated into more years in retirement rather than more years at work, has persuaded many observers that this shift(變化) will lead to slower economic growth, while the swelling(漸增的) ranks of pensioners will create government budget problems.Policies are partly responsible. Many European governments have abandoned policies that used to encourage people to retire early. Even the betteroff must work longer to have a comfortable retirement. But the changing nature of work also plays a big role. Pay has risen sharply for the highly educated, and those people continue to reap(獲得) rich rewards into old age because these days the educated elderly are more productive than the preceding(先前的) generation. Technological change may well reinforce(強化) that shift: the skills that complement(補充) computers, from management knowhow to creativity, do not necessarily decline with age.【解題導語】本文主要講述了在發(fā)達國家有專業(yè)技能的人的工作年限更長及其原因分析。1What is the common phenomenon in the workforce in rich countries?AYounger people are replacing the elderly.BWelleducated people tend to work

paragraph probably refers to “ ”Aa completely different environmentBpractical knowledge and technical skillsCa better understanding of policy changesDthe courage to face difficulties and

use it.I decided to teach her”可推知，作者的母親對電腦所知甚少，此處指電腦知識(knowledge)。2C根據(jù)上文中的“So I decided to give her one of my old computers to help her pass the time”可知，作者給母親一臺自己的舊電腦是讓退休的母親自己玩。play with.“玩”。3A隨著時間的推移，作者發(fā)現(xiàn)(found)電腦幾乎沒被碰過。4C根據(jù)下文中的“I decided to teach her”可推知，母親并不知道怎么(how)使用電腦，于是作者決定教她。5C根據(jù)空處前一句“I decided to teach her”和空后的“and she seemed OK with what I said”可推知，作者給母親講解(explained)了相關的電腦知識。6A根據(jù)語境可知，空處應填連詞and，表示“然后，接著”。7D結合語境可推知，母親不會玩電腦，感到很泄氣(discouraged)。8D根據(jù)空前的“The screen saver(屏幕保護程序)had appeared”及常識可推知，電腦出現(xiàn)屏幕保護程序，母親不知道怎么把它關掉。turn off“關掉”。9A根據(jù)空后的“and it didnt work”可推知，母親因為不懂得怎么關掉屏幕保護程序，于是就按(hitting)了每一個鍵。10B根據(jù)語境可推知，作者教母親稍微晃動(shake)鼠標即可。下文中的“start shaking it”也是提示。11B根據(jù)語境可推知，作者是讓母親移動鼠標，喚醒電腦。wake

up)，在空中搖晃。13A根據(jù)語境可推知，母親不會玩電腦，拿著鼠標亂晃，結果電腦屏幕(screen)全黑了。14D根據(jù)語境可知，作者被母親搞笑的行為(action)給逗樂了。15C根據(jù)語境可知，作者越笑，母親越生氣(angrier)。16A根據(jù)空后的“she decided to figure the thing out herself”可推知，身為老師的母親對作者教自己玩電腦這件事很有看法，認為作者沒有耐心(impatient)。17C根據(jù)語境可推知，作者幫助母親走出了害怕(fear)損壞東西的陰影，鼓勵母親再嘗試一下。18D參見上題解析。experiment“嘗試”，符合語境。19B根據(jù)語境可知，母親自己制作了一張賀卡(greeting card)

teaches us how to write stories and encourages me about his own experience.He told to me he was born in a poor family.As a little boy，he has a dream to become a famous writer.He worked hardly and overcame thousands of difficulty.Finally，he entered a university in that he wrote many story books.Up till now，aging only forty，he has been very famous around the country.【答案】Mike，a famous writer，lives just next door to me.He is always ready give a helping hand to others， he enjoys great popularity in the neighborhood.He often teaches how to write stories and encourages me his own experience.He told me he was born in a poor family.As a little boy，he a dream to become a famous writer.He worked and overcame thousands of .Finally，he entered a university in he wrote many story books.Up till now， only forty，he has been very famous around the country.第一處：ready后加to。考查動詞不定式。be ready to do sth.為固定用法，意為“準備好做某事；樂于做某事”。第二處：but改為and/so?？疾檫B詞。Mike樂于助人，因此他在社區(qū)很受歡迎。根據(jù)語境可知，此處用and/so連接兩個并列分句。第三處：us改為me?？疾榇~。第二段談及的都是Mike與作者本人之間的事，所以us改為me。第四處：about改為with?？疾榻樵~。Mike用他自己的經(jīng)歷鼓勵作者。with在此意為“以，使用”。第五處：刪除to。考查介詞。tell sb.sth.為固定用法，意為“告訴某人某事”。第六處：has改為had?？疾闀r態(tài)。根據(jù)句中的As a little boy可知，此處敘述的是過去的事，故用一般過去時。第七處：hardly改為hard?？疾楦痹~。Mike學習努力，克服了很多困難。hard“努力地”，符合語境。hardly意為“幾乎不”。第八處：difficulty改為difficulties?？疾槊~的數(shù)。根據(jù)句中的thousands of可知，此處用名詞的復數(shù)形式。第九處：that改為which?？疾槎ㄕZ從句。定語從句的先行詞為university，關系詞作介詞in的賓語，所以用“in which”引導定語從句。第十處：aging改為aged。考查形容詞。aged為形容詞，意為“歲”，符合語境。6EDBC3191F2351DD815FF33D4435F3756EDBC3191F2351DD815FF33D4435F3756EDBC3191F2351DD815FF33D4435F3756EDBC3191F2351DD815FF33D4435F3756EDBC3191F2351DD815FF33D4435F3756EDBC3191F2351DD815FF33D4435F375
