21世纪大学英语凌伟卿答案_21世纪大学英语综合型答案四

A graduate student there who observed a first-year calculus course found that Asian-Americanstudents discussed homework,tried different approaches and explained their solutions to oneanother while the others studied alone,spent most of their time reading and rereading the text,andtried the same approach time after time even if it was unsuccessful.
该校的一位研究生在观察大一的微积分课程时,发现美国亚裔学生在一起讨论家庭作业,尝试不同的方法,并相互解释他们各自的解题方法,而其他学生则独自学习,把大部分时间用在反复阅读课文上,一次又一次地试用同一种方法,即便这种方法并不成功。
句子的主干为︰A graduate student there found that... ; there后who引导定语从句,修饰先行词a graduate student ; found后为that引导的宾语从句;其中连词while将found的内容进行比较;even i|导让步状语从句。
while在句中为连词,表示对比,意为“而﹔可是”。
例: Motion is absolute while stagnation is relative.运动是绝对的,而静止是相对的。while作连词时还有以下用法:
①引导时间状语从句,意为“当...时”。
例: We must strike while the iron is hot.趁热打铁。
②引导让步状语从句,常放在句首,意为“尽管﹔虽然”,比although和though语气轻。

前言
比尔·盖茨
对我而言,过去的二十年是一段令人难以置信的探险历程。它开始于我大学二年级时的某一天:当时我和我的朋友保罗·艾伦站在哈佛广场上,专心致志地读着《大众电子学》杂志上一篇描述成套组装式微机的文章。读到有关第一架真正的个人电脑的消息,我和保罗都兴奋不已;尽管我们当时并不确切了解这种计算机如何使用,但我们确信,它将改变我们和整个计算世界。我们的想法没错。个人计算机革命发生了,而且它已影响了数百万人的生活,把我们带入了一个以前难以想象到的境界。
现在我们大家又将踏上另一次伟大的旅程。这次旅程将把我们带向何方,我们同样不甚明了;但我同样坚信,这场革命将触及更多人的生活,把我们大家带到更远的地方。即将到来的重大变化,将是人们相互交流方式上的变化。这场即将到来的通讯革命带来的好处和问题都将比个人计算机革命所带来的好处和问题要大得多。
