题目内容
17.Thinking _______ you know _______in fact you don't know is a terrible mistake.( )A. | that; that | B. | what; what | C. | that; what | D. | what; that |
分析 认为自己知道实际上不知道的事情是一个严重的错误.
解答 答案:C.
本题第一空是宾语从句,用that引导这个宾语从句,在句中不充当任何成分,只起引导和连接作用,也没有实际意义.第二空what引导的也是宾语从句,作为动词know的宾语,故选C.
点评 本题考查宾语从句,要会分析句子的成分,并且掌握what引导主语从句表示的是一种内容,可在句中作主语、宾语或表语等.
