请问坚持……是hold on it还是hold it on?

请问坚持……是hold on it还是hold it on? 应该是hold on it还是hold on to it? I will hold on it . 请问hold it和hoid on 有什么异同? 坚持做某事,是hold on to do sth.还是 hold on to doing sth.有何区别? i will hold on it this time 坚持 的英文 是hold on 还是hang on,那一个更好? 举行的单词词组是hold on 还是hold in 坚持做某事是hold on to doing hold on的中文可以是坚持吗 hold it on、try it on\take it off\get it off hold on to your umbrella so that it doesn't Blow away. hold为
