汤圆英语-零落

复习目标:1、掌握引导宾语从句的各种连词 2、掌握宾语从句的语序——主句+连接词+主语+谓语 3、掌握宾语从句,主句与从句在时态上的呼应。 重点:语序和时态呼应 难点:语序和时态呼应;疑问词+不定式的转化;状语从句的辨析 一、宾语从句的连接词: 1、连词that,只起连接作用,在从句中不作句子成分,也无词汇意义,在口语中常被省略。 eg. He knew (that) he should work hard. 2、连词if 、whether,它们起连接作用,在从句中不作句子成分,作“是否”解,在口语中多用if。 eg. Tom don’t know if/whether his grandpa liked the present. He asked me whether or not I was coming. 一般情况下,if 和whether可以互换,但以下3种情况只能用whether: ①在不定式前:Whether to go there or not hasn’t been decided. ②在介词前:It depends on(依靠) whether it is going to rain. ③与or not连用:They are talking about whether to go there or not. 3、连接代词who, whom, whose, what, which,连接副词when, where, why, how,它们起连接作用,作句子成分,各有自己的意义。 eg. The teacher asked the new students which class he was in. I wonder where he got so much money. 【注意】1、由连接代、副词引导的宾语从句可以和“疑问词+不定式”结构转化。 eg. I don’t know how I should do with the presents. è I don’t know how to do with the presents. 2、要注意区分判断由if、when引导的从句类型. 二、宾语从句的语序: 宾语从句的语序是陈述语序,即“连接词+主语+谓语+其它成分”。特别强调:它的主语和谓语的语序是陈述语序,而不是疑问句的倒装结构。 Can you tell me who(m) do we have to see?(╳) Can you tell me who(m) we have to see?( √) The teacher asked the students what they were doing.(思考: what在从句中的成分) 陈述句变为宾语从句时,要注意人称和时态的变化,语序不变。 eg. She said, “I will leave a message on the desk.” à She said she would leave a message on the desk. 一般疑问句和特殊疑问句变为宾语从句时,也要注意人称和时态的变化,后面接陈述语序。Eg. “Where are the tickets?” I asked him. à I asked him where the tickets are. 三、宾语从句的时态呼应: 宾语从句中谓语动词的时态,常常受到主句谓语时态的制约,此为时态呼应。如果主句谓语是一般现在时或将来时,从句谓语的时态不受限制;如果主句谓语的时态是一般过去时,从句一般要随着改为相应的过去时态(一般过去时、过去进行时、过去将来时、过去完成时)。 eg. I thought (that) you are free today. (╳)
