That room is clean.是指那间屋（房间）是干净的.clean 是形容词功能
be动词后面加 cleaned 过去分词,构成了被动语态；意思就转变为 "被打扫过了“
这种语境,通常以过去时 was clearned 来表达更合适些.
如果是 was clean ,同样回复到 形容词,表达 在某个过去时间点 "原来是干净的”
这都要根据 clean 后面有没有加 -ed 来决定.
that room is cleaned是这个房间已经干净了的意思?that room was clean是那个屋子曾经是干净的意思?
that room is cleaned是这个房间已经干净了的意思?that room was clean是那个屋子曾经是干净的意思?
