it 在句中什么意思？
31。It seems impossible for us to read anything without the mind making reference to the framework knowledge_____has already acquired. A.what B.that C.which D.it 答案D，it指代什么？这句话什么意思？
这句话的意思是说，我们读一样东西的时候如果没有它大致的框架内容作基础是不可能读懂的。it是指anything,也就是我们要读的这个东西
it = "to read 。。。。 already acquired。" Please note that none of the words given can be used to fill in the blank to construct a grammatically correct sentence。
The word "we" should be used instead。 The completed, correct sentence should read thus: It seems impossible for us to read anything without the mind making reference to the framework knowledge WE HAVE already acquired。
OR: 。。。。 IT HAS ALREADY BEEN acquired。 The first sentence is a preferred one。
