【语法攻略】2014届高三英语总复习专项课件：被动语态（16张PPT）

被动语态 1. 被动语态的构成：助动词be/get＋及物动词的过去分词。 用法： (1)动作的执行者不知道是谁或难以说明时常用被动语态，如 Street lights are often turned on at six in winter. 　　 (2) 当强调动作的承受者时，用被动语态，如This kind of bicycle is not sold in our shop. 【注意】 (1) 带双宾语动词的被动语态，若将间接宾语变为被动语态中的主语，直接宾语则保留不变；若将直接宾语变为被动语态中的主语，间接宾语前则需加介词to 或for。 (2) 动词make, have, let, see, watch, hear, feel等接动词不定式作宾语补足语时，动词不定式不带to；但当它们变成被动语态时后面的不定式都须加上to，如The boss made them work ten hours a day. ⇒They were made to work ten hours a day by the boss. (3) 当句子的谓语为say, believe, expect, think, know, write, consider, report, suggest, think等时，被动语态有两种形式：①谓语动词用被动语态，动词不定式作主补。②用it作形式主语，真正的主语在后面，用主语从句来表示，如Paper is known to have been first made in China. ⇒It is known that paper was first made in China. 2. 被动语态的时态： (1)一般现在时 系动词am/is/are ＋ 动词的过去分词。 (2) 一般过去时 系动词was/were ＋ 动词的过去分词，如 The pupils were given some advice by the pianist. ⇒Some advice was given to the pupils by the pianist. (3) 一般将来时 will 或be going to ＋ be ＋ 动词的过去分词，如 These books are going to be posted tomorrow. (4) 现在完成时 助动词
