being done 与am/is/are/being done 的这个被动语态有什么区别么

Question

如题所述

Answer 1

being done是属于现在分词的被动结构，通常放在名词后面作定语；而am/ is / are being done则是被动语态，在句中作谓语。例如：
The boy being beaten by the man was his son.那个正遭男人殴打的男孩是他的儿子。
The boy is being beaten by the man.那个男孩正被那男人殴打。

Answer 2

being done 是非谓语结构，可以在句中充当主语，宾语，表语，定语，以及状语，表示该动作正在进行且与句子主语是被动关系。
例：Being laughted at by others is embarrasing. (主语) 被人嘲笑很尴尬。
He don't like being laughted at by others. (宾语) 他不喜欢被人嘲笑。
The boy being laughted at by others is Tom. (定语) 那个正在被人嘲笑的男孩是Tom。
I saw him being laughted at by others yesterday. (补语)
Being laughted at by others, he is unhappy. (状语) 因为正在被人嘲笑，他很不开心。
非谓语作状语的时候，可以与状语从句互相转换，上面一句可转换为：
Because he is being laughted at by others, he is unhappy.
am/is/are/being done 是正在进行时的被动, 表示这个动作与主语是被动，且动作正在进行。
例如：Tom is laughting at Mary. (正在进行的主动) Tom正在嘲笑玛丽。
被动： Mary is being laughted at by Tom. 玛丽正在被Tom嘲笑。

Answer 3

没有区别，being done 常以主语的身份出现而已追问

那为什么有的填空用being done····而不在前面加个be动词呢

追答

表示目的、伴随情况、作主语的时候会出现这种情况
