标题: 助动词和系动词总结+关于be的省略 [打印本页] 作者: swimswan 时间: 2011-3-7 20:15 标题: 助动词和系动词总结+关于be的省略 助动词 1）助动词是语法功能词，自身没有词义，不可单独使用，它没有对应的汉译，例如： He doesn't like English. 他不喜欢英语。 （doesn't是助动词，无词义；like是主要动词，有词义)
2） 助动词协助主要动词完成以下功用，可以用来： a. 表示时态，例如： He is singing. 他在唱歌。 He has got married. 他已结婚。 b. 表示语态，例如： He was sent to England. 他被派往英国。 c. 构成疑问句，例如： Do you like college life? 你喜欢大学生活吗？ Did you study English before you came here? 你来这儿之前学过英语吗？ d. 与否定副词not合用，构成否定句，例如： I don't like him. 我不喜欢他。 e. 加强语气，例如： Do come to the party tomorrow evening. 明天晚上一定来参加晚会。 He did know that. 他的确知道那件事。 3） 最常用的助动词有：be, have, do, shall, will, should
系动词 1）状态系动词 用来表示主语状态，只有be一词，例如： He is a teacher. 他是一名教师。（is与补足语一起说明主语的身份。） 2）持续系动词 用来表示主语继续或保持一种状况或态度，主要有keep, rest, remain, stay, lie, stand, 例如： He always kept silent at meeting. 他开会时总保持沉默。 This matter rests a mystery. 此事仍是一个谜。 3）表像系动词 用来表示"看起来像"这一概念，主要有seem, appear, look, 例如： He looks tired. 他看起来很累。 He seems (to be) very sad. 他看起来很伤心。 4）感官系动词 感官系动词主要有feel, smell, sound, taste, 例如： This kind of cloth feels very soft. 这种布手感很软。 This flower smells very sweet. 这朵花闻起来很香。 5）变化系动词 这些系动词表示主语变成什么样，变化系动词主要有become, grow, turn, fall, get, go, come, run. 例如： He became mad after that. 自那之后，他疯了。 She grew rich within a short time. 她没多长时间就富了。 6）终止系动词 表示主语已终止动作，主要有prove, turn out, 表达"证实"，"变成"之意，例如： The rumor proved false. 这谣言证实有假。 The search proved difficult. 搜查证实很难。 His plan turned out a success. 他的计划终于成功了。（turn out表终止性结果）
的解释： 81.In the major cities of industrialized countries at the end of the nineteenth century, important public places such as theaters, restaurants, shops, and banks had installed electric lighting, but electricity was in less than one percent of homes, where lighting was still provided mainly by candles or gas. (A) electricity was in less than one percent of homes, where lighting was still (B) electricity was in less than one percent of homes and lighting still (C) there were less than one percent of homes with electricity, where lighting was still being (D) there was less than one percent of homes that had electricity, having lighting that was still (E) less than one percent of homes had electricity, where lighting had still been
正确选项是A
关于B的解释是：and lighting still provided省略了was,因为这里was作为助动词,而前一个并列句的was是系动词, 功能不同,不能省略.
关于可以省略be的例子，还没有注意到过，盼NN补充

prep上找到一个： Once the economic and social usefulness of the motor was demonstrated and its superiority to the horse proved, ... (proved 前省略了 was)作者: aeoluseros 时间: 2011-3-12 17:12
其实这里proved不是被动语态。proved前面没有省略was。prove是用主动表被动的。作者: swimswan 时间: 2011-3-14 19:09
