不是,是同位語(yǔ)從句.
that 引導(dǎo)的同位語(yǔ)從句來(lái)解釋it那怎樣它就成了一個(gè)賓語(yǔ)從句了？I know the sentence's mean that my classmates want to know.可以嗎原來(lái)那個(gè)句子把it去掉，i know that classmates XXXXX這個(gè)就是that引導(dǎo)的賓語(yǔ)從句了?；蛘吣憬o的第二個(gè)句子里也是賓語(yǔ)從句，不過(guò)最好說(shuō)成I know that the sentences mean that my classmates want to know.這個(gè)是雙賓語(yǔ)從句，雙賓語(yǔ)從句中第一個(gè)that不能省略的
