　　Dying patients especially—who are easiest to mislead and most often kept in the dark—can then not make decisions about the end of life: about whether or not they should enter a hospital, or to have surgery; about where and with whom they should spend their remaining time; about how they should bring their affairs to a close and take leave.
　　Computer crime, a phrase denoting illegal and surreptitious attempts to invade data banks in order to steal or modify records, or to release over computer networks software called a virus that corrupts data and programs, has grown at an alarming rate since the development of computer communications.
　　Hence, though the normal child masters some 80,000 words in sixteen years — about fourteen per day— little of this learning takes place in school.

　　要點分析和參考譯文
　　要點：要點該句中破折號內得成分是插入語。介詞about 之后三個分別由“whether or not”“where and with whom”“how”引起得從句做其賓語。動詞短語to bring to a close意為“to cause to come to an end”; “to take leave”意為“say goodbye to sb.”
　　參考譯文：特別是瀕臨死亡的病人——他們最容易受騙，也最會被蒙在鼓里——從而不能做出臨終前的有關抉擇：是否要住院，是否要進行手術，在何處與何人度過剩下的一點時光，以及如何處理完自己的事后再告別人世。
　　要點：本句的主句是“Computer crime grams, has grown at an alarming rate……”逗號之間的插入結構“a phrase……programs”是主句主語“Computer crime”的同位語。
　　參考譯文：隨著計算機通信的迅速發展，計算機犯罪以令人震驚的速度增長。計算機犯罪這個術語指的是用非法的，秘密的手段入侵數據庫，以便偷取或修改數據庫資料，或是在計算機網絡中散布病毒軟件，這些病毒能毀壞數據和程序。
　　要點：hence，就這樣，副詞表示結果。Though引導讓步狀語從句，從句的主語為the normal child, 謂語為master, about fourteen per day為插入語，起補充說明的作用，主句的主語為little of this learning; 主句的謂語是takes place
　　參考譯文：這樣，盡管正常的孩子在16年里能掌握大約8萬個單詞，大約一天學14個，但只有很少一部分是在學校里學來得。
