作者:沈建林 杨素琴 在复合句中作宾语的从句叫做宾语从句。在实际运用中,要想真正学好宾语从句,必须注意以下几个方面: A. 正确运用引导词 1) 当宾语从句是由陈述句转变而来时,引导词为that (that在口语或非正式文体中可以省略)。 下列动词后面常跟that 引导的宾语从句:say, think, hope, hear, feel, decide, agree, mean, remember, wish等。如: I hear that English is useful. "be+形容词"结构后也常接that引导的宾语从句,如be加afraid, glad, happy, pleased, sure, surprised, thankful, worried等。如: I'm afraid that we will have an English test tomorrow. 2) 当宾语从句是由特殊疑问句转变而来时,引导词由原来的疑问代词或疑问副词充当。如: I don't know what he said. (疑问代词) He asked me where I live. (疑问副词) 3) 当宾语从句是由一般疑问句转变而来时,引导词为whether或if。 下列动词或词组后面常接whether或if引导的宾语从句:ask, know, find out, tell, wonder, understand, question, doubt等。如: I doubt whether he will succeed. I wonder if you can help me. B. 正确运用时态 1) 主句为过去时态,从句也要相应地选用过去的某种时态。如: He told us that he felt ill. He said he would go to the park the next day. He asked me what I was doing then. 2) 主句为一般现在时、一般将来时或祈使句时,从句不受主句时态的影响,可以根据意义需要任意选择一种时态。如: I hear Mrs. Smith will arrive here in an hour. I won't take back what I said. Please tell us when the meeting will be over. 3) 当宾语从句叙述的是客观事实、真理、自然现象、名言警句及谚语等时,不管主句是什么时态,从句一律使用原时态(通常是一般现在时)。如: The teacher told us that the earth moves around the sun. He said time is money. C. 正确运用语序 在含有宾语从句的复合句中,不管宾语从句由哪种句式转变而来,从句都必须采用陈述语序,即"引导词+主语+谓语+(其他)"结构。如: We don't know where he lives. 句中where he lives不能改为where does he live。 D. 正确运用标点 宾语从句句末的标点符号应根据主句来确定。如: I don't know ... . Where is he from? → I don't know where he's from. Can you tell us ...? Is everybody here? → Can you tell us if everybody is here? E. 人称的呼应 在宾语从句中,从句的人称有时需根据主句的需要而作相应的变化。如: Mike asked me... When were you born? → Mike asked me when I was born. He told me... I will visit you next week. → He told me he would visit me the next week. F. 否定的转移 当主句的谓语为think, believe 等, 且主句主语为第一人称时,宾语从句中的否定词not 应移到主句的谓语动词上来。如: Their team can't beat ours. → We don't believe their team can beat ours. G. 反意疑问 含有宾语从句的复合句在进行反意疑问时,疑问部分通常由主句来决定,但当主句中含有think, believe 等动词且主句主语为第一人称时,疑问部分则需由从句来决定,不过应注意否定转移的情况。如: He said Jack failed the exam, didn't he? (由主句来决定。) I don't think you are right, are you? (由从句来决定,且应考虑否定转移的问题。) |
