有can't help to do sth这种结构吗?请加以解释用法,意思.

有这种结构，can't help to do sth是指不能帮助别人作某事；eg：i can't help you to finish your work.而can't help doing sth是指禁不住作某事
eg：i can not help laughing.
这句话译为“我禁不住笑了”

有啊.是不得已做某事.
he can't help to tremble because of his illness.
他因为疾病无法控制地发抖..
要与cant help doing区分开,doing是迫不及待做某事
