being問題

答：
Being opened 如果唔加 verb to be 在前面 (即係 is am are was were 果d)，咁就係名詞，被動式的名詞，換句話說，如果用主動式表達的話就會係 opening。


轉為 The sound of desks that were opened could be heard out.
ok?

答：可以，不過錯左少少，were 要改為 was，因為 The sound 係數唔到，所以係單數。留意，The XX of XX 如果要辨別單數定眾數，並不是睇後者，而是睇前者才對。
全句為 The sound of desks that was opened could be heard out.


轉為 The sound of desks opened could be heard out.
ok?

答：不可以，因為沒有了被動的意思。

being opened
有被動既意思
通常用親being..都係有被動既意思

were opened正常黎講係可以既
睇下用係咩tense度


不過句句子好似有d問題
