I think its fun

its 为什么不用it's
原句是she likes playings sports,and she thinks its fun

应该是 I think it's fun.

fun 这个词既可以是名词,也可以是形容词,fun前面如果加了形容词,例如great,就可以作为名词来用,例如:I think it's great fun. 如果fun前面没有形容词,则可以把fun理解为形容词, 例如:I think it's fun. 但不能说:I think its fun. 楼主给的例句可以合并为一句:She thinks it's fun to play sports.

it's funny吧
系表结构
fun是名词,
funny才是形容词
its fun单独用在thinks后面不行的,因为think后面要跟的是一个完整的结构,不能只是一个名词。
