宾语从句new.ppt

一、宾语从句的概念 宾语从句属于名词性从句，在句中作主句的宾语。 eg. We know Mr Green teaches English. She asked if these answers were right. 只能用whether不能用if的情况 1.在介词后面： I’m thinking of whether we should go fishing. We are worried about whether it will rain tomorrow. 2.在动词不定式前： They asked me whether to go skating. 3.当与or not连用，或提出两种选择时: I don’t know whether he’s free or not. Mary asked whether I was doing my homework or not. Tell me whether you’d like to go shopping or tidy the room. 4.宾语从句提前时： Whether this is true or not, I can’t say. （二）语序：陈述句语序 当从句的原句为以下句子以及what, who作主语时，语序不变： What’s wrong? What’s the matter? What’s happening? What happeneed? eg:I don’t know what’s the matter. Can you tell me who is over there? 主句用现在时或将来时，从句可用任何时态。主句用过去时，从句用与过去相关的时态。 1.从句说明的是一般真理、客观事实、自然现象、名言时，仍用现在时。 Dad told us that it is better to do than to say. He told the boy that three and three is six. He told me the earth moves around the sun. 2.从句中有具体时间状语，即使从句动作发生在主句动作前，仍用一般过去时。 The teacher told me she was born in 1960. 1.时态的变动： He said，“I’m going home.” He said （that） he was going home. Jack said ,“Peter，I came to return you the dictionary.” Jack told Peter （that） he had come to return him the dictionary. 2.代词的变动: “I have lost my bike,”he said. He said (that) he had lost his bike. He said to me,“I don’t like you.” He told me （that） he didn’t like me. The boy said,“I’ll call again in the afternoon.” The boy said (that) he would call again in the afternoon. 3.时间状语的变化 now——then today——that day this week——that week yesterday——the day before last week——the week before tomorrow——the next day next week——the next week ago ——before 4.指示代词和地点状语作相应的变化 this——that these——those here——there come——go 使用宾语从句要注意的问题 在think, believe, suppose, expect等动词所跟的宾语中，如果从句谓语是否定的，一般要将否定词移到主句谓语上，而将从句宾语变为肯定形式。 I don’t think he has time to play football with you. 我想他没有时间和你踢足球。 I don’t suppose it is the rush hour yet. 我估计现在未到（交通）高峰时间。 在 hope ,believe ,suppose ,guess, think 等动词以及“ I’m afraid ” 等表达法的后面，可用 so 代替一个
