1.[B] 推理判断题。解答本题的关键在于推断single file的意思。该句把精子通过试管的情形与牛群被赶入牲口圈的情形作对比，结合single一词本身的意思，可以推断single file是“一个接一个”的意思，只有选项B能表达这个意思，由此也可否定选项D。选项A最具干扰性，原句是把精子通过试管的情形比作牛群被赶人牲口圈的情形，而选项A说的是测定精子内DNA的方法与放牧的方法相同，显然选项A只是引用了原文的某些词语，但表达的意思与原文却截然不同。
2.[C] 事实细节题。第1段第3句which引导的非限制性定语从句修饰的是the father's sperm，而不是插入语the mother’s egg,因此选项C正确。
3.[D] 推理判断题。第2段第1句中的genetic暗示有些疾病是遗传的，即如选项D所述。第2段第1句同时表明选项A的说法是不全面的。选项B与第2段最后两句正好相反。第1段前两句说明选项C是错误的。
4.[A] 事实细节题。第1段倒数第2句中的由which引导的定语从句表明选项A的叙述正确。
5.[C] 观点态度题。文章第2段中作者给出了一些反对者和赞成者的观点，但是没有加以评论，可以看出作者的态度是中立的，故选项C正确。

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(已废弃的) 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. Children will still go to schoolthough, until another place is created where they can make friends and develop social skills.

1.[C] 事实细节题。只要知道第1段第2句中的关键词accelerate意为speed up“加速,加快”，就可以排除其他选项。
2.[B] 事实细节题。本题考査对比处。作者在第1段第5句中通过previously将过去与现在作对比,指出现在传递消息的途径与过去不一样了，由此可判断B为正确选项。本题最具干扰性的是选项C，第1段倒数第3句提到以 后邮递员将会消失，但这并不意味着人们不再写信和寄信，以后可能会有新的送信方式，因此选项C是不对的。
3.[C] 词义推断题。they所在的句子是第1段倒数第2句，本句中两个they的指代是一样的，因此，只要找到第一个they的指代就能找到答案了。根据本段倒数第3句中“Not only postmen but also clerks and secretaries will vanish”及倒数第2句中的“All the routine tasks they perform...”可推断，they是指上一句中的postmen，clerks 和secretaries 。
4.[B] 推理判断题。本题考査列举处。在第2段,作者列举了律师、医生、教师将会受到的新技术的影响，第3句指出医生的电子竞争者会做出更快更准的诊断,从而确定选项B说法正确，而选项A和C与原文不符，选项D言过其实，且缺乏合理的原文依据。
5.[A] 观点态度题。作者举出了大量实例暗示和告诫人们：正因为人类技术的发展日新月异，许多职业的存在都将受到威胁，人们应该采取积极态度以应对这种变化。选项B显然与第1段最后一句相悖;选项C无合理的推 断依据;文中虽提到新技术会在多方面影响人类,但并不能由此推断机器会控制人类,所以选项D不对。
