My friend JOHN always has something tell me.He knows

我的朋友约翰总会有些事儿给我讲,他深知年轻人必须让比自己年长、阅历更丰富的男人多多启发.比如说,什么样的人值得信任、如何关心别人以及怎样才能活得最充实.
My friend John always has something to tell me.He knows so much that young men have to have older and more worldly wise men to tell them,for instance,who to trust,how to care for others,and how to live life to the fullest.

我的朋友John一直有事想告诉我，他知道……后面没了？
