He will never let his secret be discovered 中是不是省略了介词to 如果是 为什么

Question

如题所述

Answer 1

不是。
不定式有两种形式，一种是带to，另一种不带to，
let/ make sb do sth【即后加不带to 的不定式，但改成被动需带to】。不是介词，而是不定式符号。

Answer 2

let 是使役动词，接的是省略to的不定式。
只有在被动语态的受词补语用不定词,不用原形不定词。
这个句子是虽然看起来像被动句，实际上还是主动句。
他让秘密不被发现。 如果是秘密做主语就是被动的了
His secret will never be let to be discovered.
是不是被动要看let用的是不是被动形式。

Answer 3

没有
let + n + v
比如说let's go就是let us go
没有to

句中是被动时态
let + n+ be done追问

be discovered是什么成分是his secret的定语吗
