中考网整理了关于中考复习知识点之宾语引导词的判断，希望对同学们有所帮助，仅供参考。  1. that，后跟陈述句，无意义，口语中可省略。 【例】They know（that）she is an English teacher. 分析：从句she is an English teacher是一个完整的陈述句，不缺少任何成分（如主语、宾语等），引导词用that。 2. if和 whether表“是否”，多数情况下二者可互换。 【例】I wonder if/ whether you have already finished your homework. ※ 易错点：只用whether不用if的情况 ① 当与or not连用时 【例】I wonder if/ whether you have already finished your homework. = I wonder whether you have already finished your homework or not. = I wonder whether or not you have already finished your homework. 总结：无论or not位置在前面还是后面，出现or not就只用whether。 ② 宾从作介词的宾语时 【例】He was worried about whether he would lose his job. 介词about后面，宾从的连接词只能用whether。 ③ Whether引导的宾从放在句首时 【例】Whether we can arrive there on time, I am not sure. 3. 特殊疑问词。当宾语从句是特殊疑问句时，由疑问代词（what、who、which、whose、whom等）和疑问副词（where、when、why、how）引导。 ※ 总结：问什么就用什么 【例】I didn’t know who was late for school this morning. （问人——who） 【例】I don’t remember when we arrived here. （问时间——when） (责任编辑：admin) |
