15、常简化为“宾语+宾语补定语”结构，宾补多为不带to的不定式或 动词的现在分词。如：I heard that she sang some songs in the next room.I heard her sing some songs in the next room.3.由特殊疑问词引导的宾语从句，若从句的主语与主句的主语或间接宾语相一致时，可简化为“疑问词+不定式”结构。如：I dont know what I should do.I dont know what to do.,比一比 I dont know where I should go.Tell me how I can do
