continued continuing continuous continual的区别
continued continuing continuous continual这个4个形容词的具体区别是什么

continuous 连续不断的(强调一个动作没有间断过)
continual 反复的,频繁的(强调一个动作在某个时期反复出现)
continued和continuing可以互换,都表示“连续不断的”“继续不变的”,但是它们只能用于名词前.
其实总的来说,它们之间的差异正逐渐消失,特别是continual亦含有continuous相同的意义,尤指不愉快的事:Life was a continual struggle for them.生活对他们来说是不断的挣扎.
