辨析lament deplore bemoan bewail的区别？

lament:
1 [intransitive and transitive]to express feelings of great sadness about something: 
2 [transitive]to express annoyance or disappointment about something you think is unsatisfactory or unfair


bewail:
to express deep sadness or disappointment about something
两个词都表达极度悲伤，但lament还有对某事失望的意思


deplore:

disapprove of something very strongly and criticize it severely, especially publicly
中文就是苛责


bemoan:
to complain or say that you are disappointed about something
抱怨

bemoan的意思是 to complian or say that you are not happy about something，表达一种不满和失望之情，比如 They sat bemoaning the fact that no one would give them a chance. （他们坐在那抱怨没有人给他们一个机会。）
bewail的意思是to express great sadness about something，表达的是伤感之情，不是抱怨和失望，所以和bemoan的区别在此。比如：Her tears bewail the great loss she has suffered. (她的眼泪表达了对她巨大的损失的伤感。）
lament做动词的意思是 to feel or express great sadness or disappointment about sb/sth，表达的是伤感之情或者失望之情，通常在字典上将bewail和bemoan列为lament的同义词，不过根据上面列举的原意来看，这几个词的意思还是有所区别。lament还有一个名词词性，意思是a song, poem or other expression of great sadness for sb who has died or for something that has ended，大概和中文里面的“挽歌”有点像。当然，从意思中可以看出，不一定是歌曲，也可以是诗歌或者其它艺术形式，所缅怀的对象也可能不是人，也可以是终止的事情。“挽歌”更确切的说法应该是eulogy。
deplore是四个词里面意思最不靠近的一个词，意思是to strongly disapprove of sth and criticize it, especially publicly，公开批评某事。比如Like everyone else, I deplore and condemn this killing. （像其他人一样，我也谴责这个杀戮的行为。）
