Question

高手们快来帮忙解题啊!

题目如下:
_____is very important____you should not pretend____you know ___you don't.
A,That...that...what...what
B,It...that...what...that
C,That...what..that...what
D,It...that...that...what
答案是D,想问为什么?

Answer 1

It is important that....是句型，课本里应该有。
You should not pretend that ...后跟宾语丛句。
You know....后跟宾语丛句。
最后what you don't 是宾语丛句，此句中省略了谓语know.即应为you don't know.
全句的意思是：重要的是你不应该不懂装懂。

Answer 2

pretend that 引导后面的从句,
you know what you don't 是一个整体,
这个句子的意思为 知之为知之,不知为不知,这一点是很重要的.

Answer 3

it was + adj. + that从句 是固定句式
从句部分pretend是谓语动词
后面还是一个宾语从句
what you don't作know 的宾语
understand?

Answer 4

IT和第一个THAT构成一个由形式主语引导的句型，THAT后是真正主语；第二个THAT是PRETEND后的宾语从句，WHAT YOU DON'T是惯用语句， WHAT一词意思是“所。。。”如'WHAT YOU SAID'意思是 你所说的。
这几个关键词都是不可替代的，所以只有D正确。

Answer 5

从句套从句
而且从意思上来说也应该是D

Answer 6

D
It is ... that ...后跟宾语从句。
pretend that ...后跟从句。
这个"pretend that you know what you don't"意思是“你装做知道你实际上不知道的东西。”
