(句子作宾语） 宾语从句即句子作宾语，而不再是一个词或短语作宾语。宾语从句： 概念：在复合句中，由一个句子充当宾语,这个句子叫做宾语从句。 宾语从句由“关联词+主语+谓语”构成。 引导宾语从句的关联词有that, if, whether, what, who, where, why和how等。 宾语从句要用陈述句语序。Grammar总结一下吧！宾语从句的三要素：一、关联词：that, if, whether, what, who, where, why和how等。 二、时态：1.当主句为一般现在时时态时，从句根据需 要来确定时态。 2.当主句用一般过去时时态时，宾语从句要用过去的某种时态。注意：当从句是客观真理的时候，无论主句什么时态，从句一律用一般现在时。 三、语序：宾语从句用陈述句语序，即 “主语+谓语”。如： e.g. He asked me where my school was. I didn’t know who she was. 由从属连词that引导的宾语从句注：that 在句中无词汇意义，在从句中不能充当成分， 在口语当中往往省略e.g. I hear (that) _____. （一小时后他会回来） He said (that) _____. （他非常想念我们） The teacher told us (that) _____. （地球围着太阳转） he will be back in an hour he missed us very much the earth moves around the sun注意：当从句是客观真理的时候，无论主句什么时态，从句一律用一般现在时由从属连词whether, if 引导的宾语从句e.g. 1. Ask him _____. （他是否能来） 2. I don’t know _____.（是否要下雨） whether (if) he can come whether it is going to rain or not当句末为or not时，引导词只能用whether而不能用if.If 与whether 的区别I don’t know _____ he will come or not.
