happen to do or happen doing? sb.happen to do sth. 用happen to do和happen to sb.造句 Do you happen to have twenty dollars on you 句中的happen 怎么翻译 happened to do和‘happen to do ;区别? happen to do sth什么意思 chance/happen/seem/appear/pretend to do happen to do sth的汉语是什么? happen to do 中的to do 在句子中做什么成分happen vihappen 为不及物动词不及物动词后面也可以加宾语吗？ happen to sb和happen to do sth 造句并解释造的句子 问个关于happen的用法的问题.happen.不是happen to do sth.那么 碰巧去做,碰巧正做,和碰巧已做.是不是分别是happen to do,happen to doing,happen to have been?
