2. 有些动词用主动形式表示被动意义。This pen writes well. This new book sells well. 3. 感官动词或使役动词使用省略to的动词不定式，主动语态中不带to，但变为被动语态时，须加上to。 例：make somebody do something→somebody+ be +made to do something see somebody do something→somebody +be +seen to do something The boss made the little boy do heavy work.→The little boy was made to do heavy work by the boss. 4. 如果是接双宾语的动词改为被动语态时，直接宾语(物)作主语，那么动词后要用介词，这个介词是由与其搭配的动词决定。 He gave me a book.→A book was given to me by him. He showed me a ticket.→A ticket was shown to me by him. 5. 一些动词短语用于被动语态时，动词短语应当看作一个整体，而不能丢掉其中的介词或副词。 We can’t laugh at him. →He can’t be laughed at by us. 常见考法 对于语态考查，多以单选、词语运用的形式考查学生在具体语境中灵活运用被动语态的能力。一般情况下，会综合考查时态和语态，这时，要根据语境和动作发生的时间来确定时态，然后再确定语态。 典型例题：–Could you tell me whom the radio__________by? -Sorry, I have no idea. A invents B invented C is invented D was invented 解析：题干的意思是“你能告诉我收音机是谁发明的吗?”，发明收音机是过去的事，所以用过去时，排除 A和C;而radio和invent 构成被动关系，应用被动语态，排除B 答案：D 误区提醒 有些动词后跟不带to的不定式作宾语补足语，但改为被动结构后要加上“to”，这一点我们必须注意。 典型例题：The young man was often seen _____ by the lake. A to draw B to drawing C draw D drew 解析：这是2007年济南的中考题。“看到某人做某事”为see sb.do sth.。句中动词原形是省略to的不定式，在被动语态中要还原to。 答案：A (责任编辑：admin) |
