This book will show you ________ can be used in other contexts
A. how you have observed
B.what you have observed
C. that you have observed
D. how that you have observed
本人对what引导的主语从句不是十分了解,希望大家能够给予一些建议。(本人是英语初学者,莫要太深奥)
答案B是一个名词短语,相当于一个名词,可以作主语,而这里恰好缺少一个主语,所以是唯一正确的选项。其他选项都不是名词短语,所以都不可以做主语。
This book will show you what you have observed can be used in other contexts(错误句子)
解答:以上句子有3个谓语动词,但根据连词个数=谓语动词个数-1的原则,连词个数=3-1=2,即句子应该有2个连词,但是句子只有1个what连词. 所以句子不正确,应该在what连词前面加1个that连词.即that what。(what引导主语从句,但是宾语从句缺少连词that,即show sb sth, that 宾语从句充当主句will show的直接宾语成分)
下面的句子为正确句子
This book(主语)// will show (谓语动词)//you(间接宾语)// that what you have observed can be used in other contexts(直接宾语)(what引导主语主语从句,即what从句充当that宾语从句中主句的主语成分)
that引导宾语从句语法结构分析如下
引导宾语从句连词:that
(宾语从句的)主语:what you have observed
(宾语从句的)谓语:can be used
(宾语从句的)状语:in other contexts
备注(1):1个连词引导主从复合句(不省略情况下)必须拥有2个谓语动词,从句1个谓语动词,主句1个谓语动词。所以连词的数量+1=谓语动词个数。
备注(2):show sb that结构中,如果that宾语从句中又包含1个wh-从句,则引导宾语从句that连词不可以省略。
以下句子也是正确的
The book(主语)// will show (谓语动词)//you(间接宾语)// how what you have observed can be used in other contexts(how引导宾语从句,how在宾语从句充当方式状语成分).
how引导宾语从句语法结构分析如下
引导宾语从句连词:how(作方式状语)
(宾语从句的)主语:what you have observed
(宾语从句的)谓语:can be used
(宾语从句的)位置/地点状语:in other contexts
(宾语从句的)方式状语:how

如果是初学者,先看些更简单的。这里面的选项全是错的。
正确的是
The book will show you (that what) you have observed can be used in other contexts.
The book will show you (how what) you have observed can be used in other contexts.
选项B把that省略了,是不妥的,that只有不影响句意或阅读时才可以省略。但是如果省略了,你在读的时候,会发现很容易把show与what搭配的这个结构读成一个双宾结构。读到后面又发现不是。影响阅读时,that就不可省略
