I know what they are looking for.这句话是对的
可是改成如此的话对不对啊
I know that they are looking for what.
另外陈述语序的意思是啊,第一句话里what引导的宾语从句在从句里作宾语,那从句不就是宾语+主语+谓语了吗?那这还是陈述语序吗?我理解的陈述语序是像句二从句一样的主+谓+宾的语序,是否我理解错了。
陈述语气一般体目前主谓语序的变化。如:You are a student. (陈述)Are you a student? (疑问)句中假如有特殊疑问词,如what, where, when,why等一般要放在它引导的句子句首,不论是陈述还是疑问,也不论是宾语还是状语。如:What are you doing? I don't what you are doing now. 宾语放在句首也可以是陈述语气,表示强调。如: What he said I didn't understand. 这种使用方法多见于文学语言。所以你的句子 I know what they are looking for 是正确的。当然口语里也会出现例外,如: You're looking for what? 这是不规范的使用方法。
