英语被动语态和动词过去式表被动的区别

''听起来更有礼貌''一句中
该用It is sounded more polite
还是It sounded more polite
以前听过一个动词的过去式本身就表被动的说法,一直很糊涂,谁能给讲讲,谢谢

It sounded more polite
sound在这里做“系表结构”和you looks beautiful 你看起来很漂亮 一样

你说的那个是不是主动表被动？
The bike needs mending
那辆自行车要修了。

本身表示被动的动词不见得是过去时。比如，

--The soup tastes salty. (汤尝上去太咸了。)taste就是被动动词。
--It sounds more polite. (里面不能用is，因为动词本身就有被动含义)

被动语态的结构是：主语 + be动词（不同时态） + 行为动词过去分词

The table is cleaned everyday.
The table is being cleaned now.
The table will be cleaned in 10 minutes.
The table was cleaned last night.
The table has been cleaned.

It is sounded more polite
听我没错
