is the watch in the lost and found sase翻译
1个回答
Who the watch belongs to was lost is unknown.Who the watch belongs to was lost是主语从句,is unknown是系表结构.主语从句省略了that,Who the watch belongs to (that) was lost,(that) was lost是watch的定语从句,watch是先行词,这是一个后置定语.
追问：
什么情况下,That可以省略,麻烦详解,
回答：
that引导宾语从句和定语从句时一般可以省略,在主语从句、状语从句、表语从句等中一般不能省略.主要是要看that在句子中起的作用,如果起指代作用而且其所指代的部分在句子中出现,that就可以省略.也就是主要看that在句子中是否做成分,这个成分有没有别的词充当,如果有就可以省,如果没有就不能省.eg：That is what the story of mankind has on the whole been like.He is ashamed that he was rude.
