看，认为，觉得，想，以为，考虑，思考，

看：watch,see,look 认为：how about,think,in one's opinion,

first i would like to compare 看 and 认为！ 看：example: 我看这个问题不简单！ I think this is not a simple problem.(this is a usage to express your opinion to the problem. in this sentence you can use 认为 to take place of 看！but there is a little difference: 认为 is more formal than 看！ as for other verbs of thinking : formal verbs: 认为、想、 持有。。。观点 others：觉得

看：是直观 认为：主观思考
