If you want tokowm that piease iook for bookor .computer or

首先,这个好多写错的单词.我猜应该是这样的：
If you want to know that,please look for book,computer or ask others.
然后,这是句非常chinglish(中式英语)的说法,意思是：如果你想知道那件事,要么查阅书籍,要么上网查询资料,要么请教别人.
我建议的表达方式为：You can either refer to the books,or search the internet,or ask someone,if you want to know that.
