　　1.[B] 推理判斷題。解答本題的關(guān)鍵在于推斷single file的意思。該句把精子通過(guò)試管的情形與牛群被趕入牲口圈的情形作對(duì)比，結(jié)合single一詞本身的意思，可以推斷single file是“一個(gè)接一個(gè)”的意思，只有選項(xiàng)B能表達(dá)這個(gè)意思，由此也可否定選項(xiàng)D。選項(xiàng)A最具干擾性，原句是把精子通過(guò)試管的情形比作牛群被趕人牲口圈的情形，而選項(xiàng)A說(shuō)的是測(cè)定精子內(nèi)DNA的方法與放牧的方法相同，顯然選項(xiàng)A只是引用了原文的某些詞語(yǔ)，但表達(dá)的意思與原文卻截然不同。

　　2.[C] 事實(shí)細(xì)節(jié)題。第1段第3句which引導(dǎo)的非限制性定語(yǔ)從句修飾的是the father's sperm，而不是插入語(yǔ)the mother’s egg,因此選項(xiàng)C正確。

　　3.[D] 推理判斷題。第2段第1句中的genetic暗示有些疾病是遺傳的，即如選項(xiàng)D所述。第2段第1句同時(shí)表明選項(xiàng)A的說(shuō)法是不全面的。選項(xiàng)B與第2段最后兩句正好相反。第1段前兩句說(shuō)明選項(xiàng)C是錯(cuò)誤的。

　　4.[A] 事實(shí)細(xì)節(jié)題。第1段倒數(shù)第2句中的由which引導(dǎo)的定語(yǔ)從句表明選項(xiàng)A的敘述正確。

　　5.[C] 觀點(diǎn)態(tài)度題。文章第2段中作者給出了一些反對(duì)者和贊成者的觀點(diǎn)，但是沒(méi)有加以評(píng)論，可以看出作者的態(tài)度是中立的，故選項(xiàng)C正確。

　　Hardly a week goes by without some advance in technology that would have seemed incredible50 years ago. And we can expect the rate of change to accelerate rather than slow down withinour lifetime. The developments in technology are bound to have a dramatic effect on the futureof work. By 2010, new technology will have revolutionized communications. People will betransmitting messages down telephone lines that previously would have been sent by post.Not only postmen but also clerks and secretaries will vanish in a paper-free society. All theroutine tasks they perform will be carried on a tiny silicon chip so that they will be asobsolete(已廢棄的) as the horse and cart after the invention of the motorcar. One change willmake thousands, if not millions, redundant.

　　Even people in traditional professions, where expert knowledge has been the key, are unlikelyto escape the effects of new technology. Instead of going to a solicitor, you might go to acomputer that is programmed with all the most up-to-date legal information. Doctors, too, willfind that an electronic competitor will be able to carry out a much quicker and more accuratediagnosis and recommend more efficient courses oftreatment. In education, teachers will belargely replaced by teaching machines far more knowledgeable than any human being. Mostlearning will take place in the home via video conferencing.

　　1.[C] 事實(shí)細(xì)節(jié)題。只要知道第1段第2句中的關(guān)鍵詞accelerate意為speed up“加速,加快”，就可以排除其他選項(xiàng)。

　　2.[B] 事實(shí)細(xì)節(jié)題。本題考査對(duì)比處。作者在第1段第5句中通過(guò)previously將過(guò)去與現(xiàn)在作對(duì)比,指出現(xiàn)在傳遞消息的途徑與過(guò)去不一樣了，由此可判斷B為正確選項(xiàng)。本題最具干擾性的是選項(xiàng)C，第1段倒數(shù)第3句提到以 后郵遞員將會(huì)消失，但這并不意味著人們不再寫信和寄信，以后可能會(huì)有新的送信方式，因此選項(xiàng)C是不對(duì)的。

　　3.[C] 詞義推斷題。they所在的句子是第1段倒數(shù)第2句，本句中兩個(gè)they的指代是一樣的，因此，只要找到第一個(gè)they的指代就能找到答案了。根據(jù)本段倒數(shù)第3句中“Not only postmen but also clerks and secretaries will vanish”及倒數(shù)第2句中的“All the routine tasks they perform...”可推斷，they是指上一句中的postmen，clerks 和secretaries 。

　　4.[B] 推理判斷題。本題考査列舉處。在第2段,作者列舉了律師、醫(yī)生、教師將會(huì)受到的新技術(shù)的影響，第3句指出醫(yī)生的電子競(jìng)爭(zhēng)者會(huì)做出更快更準(zhǔn)的診斷,從而確定選項(xiàng)B說(shuō)法正確，而選項(xiàng)A和C與原文不符，選項(xiàng)D言過(guò)其實(shí)，且缺乏合理的原文依據(jù)。

　　5.[A] 觀點(diǎn)態(tài)度題。作者舉出了大量實(shí)例暗示和告誡人們：正因?yàn)槿祟惣夹g(shù)的發(fā)展日新月異，許多職業(yè)的存在都將受到威脅，人們應(yīng)該采取積極態(tài)度以應(yīng)對(duì)這種變化。選項(xiàng)B顯然與第1段最后一句相悖;選項(xiàng)C無(wú)合理的推 斷依據(jù);文中雖提到新技術(shù)會(huì)在多方面影響人類,但并不能由此推斷機(jī)器會(huì)控制人類,所以選項(xiàng)D不對(duì)。
