中考英语一轮复习语法知识+语篇能力课件语态要点呈现与讲解(含详解)
展开语态是动词的一种形式,表示主语和谓语的关系。当主语是动作的执行者时用主动语态(某人做某事); 当主语是动作的承受者时,用被动语态(某事被人做)。
(一)各种时态的被动语态被动语态由“主语+be+及物动词的过去分词”构成,助动词有时态、人称和数的变化。
(二) 主动语态和被动语态之间的转换在主动句变为被动句时,要注意主动句和被动句中时态应该一致,同时还应该注意被动句中主语的人称和数要与谓语动词保持一致。主动语态和被动语态的转换形式主要方法:第一步:把主动语态中的宾语变为被动语态的主语。第二步:把主动语态的谓语变为be+过去分词。第三步:把主动语态的主语放在介词by之后用来说明动作的执行者,有时可以省略。
(三) 主动语态变被动语态的注意事项(1)双宾语及物动词变成被动语态时,将间接宾语或直接宾语变为主语。They gave the children many gd bks. 他们给了孩子们很多好书。→The children were given many gd bks. 或Many gd bks were given t the children.
【温馨提示】及物动词(give,send, take, bring, teach, shw, tell, make, buy, pass,get等)常常带有两个宾语,变为被动语态时可以将其中一个宾语改为主语,另一个保留不动,这种情况下的t可以省略。They gave the visitrs a warm welcme. 他们对来访者表示热烈欢迎。
→ The visitrs were given a warm welcme. 或 A warm welcme was given t the visitrs.有些及物动词(buy,make,find,get等)在被动语态中被保留的间接宾语前通常加fr,此时fr不可以省略。Mther bught me a cmputer.→ A cmputer was bught fr me. 妈妈给我买了一台电脑。
(2)含有感官动词和使役动词的主动句变为被动句。在主动语态中是不带t的不定式作宾语补足语,在变为被动语态时要加上t。He made us laugh. →We were made t laugh. 我们被逗笑了。(3)动词短语的主动语态变为被动语态,动词短语不可分。My sn is lked after by his grandma. 我的儿子由他的奶奶照顾。
(4)主动形式表示被动意义。 ①break,wash,sell,read,write等动词作不及物动词时,与副词连用常用主动形式表示被动意义。 These clthes sell well. 这些衣服很畅销。 ②feel,sund,taste,smell等动词常用主动形式表被动意义。The sngs sund gd. 这些歌听起来好听。
