怎样区分疑问句中的主语?
到底是I don't know what is the population of China还是I don't know what the population of China .老师说是I don't know what is the population of China,也就是what is the population of China是陈述句了咯,那what不就是从句的主语了么?可我实在是看不出来what是主语、谁能教教我.
希望是权威的回答啊.

解答

(1)主语是陈述说明对象或者话题,它指出陈述说明的是"谁"或者"甚麼",或者"甚麼地方"、"甚麼时间".
(2)主语是指所要说的是什麼人或什麼事,是谓语的陈述对象.
所以
I don't know 是主语,表明我,被谓语的陈述对象的人【我】；
what is the population of China 是陈述句,陈述我不知道~~~甚麽是全中国的人口.
