68. The new products become more and more time-saving because .
A. our love of speed seems never-ending
B. time is limited.
C. the prices are increasingly high.
D. the manufactures boast a lot.
答案：A
解析：每年都有更高速的新车出产, 而且新电脑也吹嘘能节省宝贵的每一秒钟。可见, 题目和选项矛盾。越来越省时是事实, 不是因为吹嘘而变得省时了。
69. What does “the days” in Paragraph 3 refer to ?
A. Imaginary life B. Simple life in the past.
C. Times of inventions D. Time for constant activity.
答案：B
解析： 回原文定位第三段该句Perhaps the days are long gone when we might listen quietly to a story on the radio, letting imagination take us into another world.也许, 我们静静聆听广播里的故事节目, 任想象插上翅膀肆意翱翔的日子, 已经一去不返了。根据前后一句可得知, 文章重点是说的高速生活和简单生活的对比。故:B选项是对原文的正确解读。而A选项的理解有偏差, 重点转移了。
70. What is the author’s attitude towards the modern technology?
A. Critical B. Objective. C. Optimistic. D. Negative.
答案：B
解析： 根据文章结构, 第一段陈述事实, 说现代高科技省时省力。第二段说高速生活的弊端。第三段说对简单生活的向往, 但最后第四段却说高科技对现代生活的积极影响。所以, 作者的观点是不偏不倚的。
71. What does the passage mainly discuss?
A. The present and past times.
B. Machinery and human beings.
C. Imaginations and inventions.
D. Modern technology and its influence.
答案：D
解析： 根据文章首尾段的大意可知, 文章重在分析高科技的利与弊。
