纸上信上“说”了什么内容用英语是“say”，还是用read？

Question

转述纸上牌子上信上说的，都是什么情况用say ，read？完型常见
辨析
在字典上有如下例句：
The full report reads as follows.
The thermometer reads 46 degrees.
There is a sign by the road, which reads "Parking forbidden".

It says in this book that women are more intelligent than men.

He had guilt written all over his face.

照字典上的解释来看，某标牌上写的东西是不会用 write的，但是read和say两个词应该不是通用的，因为在一篇完型填空中，就是标牌上写着什么，选项中既有read也有say，标准答案为read，而同样在初中的书上也出现过用say的，两者的区别？

Answer 1

应该是read，因为是人去读（看）信本回答被提问者采纳

Answer 2

平时说话都是用says，such as, This letter says bruce lee is very famous in China. 可能是在一些比较严谨古老的文学作品里letter read 的有说法吧。

Answer 3

标牌用read 信用say

Answer 4

read正规些，书面。而say 口语，不太正规
