It is good to ask when you are motivated by a desireto obtain knowledge.  My input is as follows:  When reading any scripture, it is dangerous to take it out of context.  In this particular case, Paul was talking about love and what he meant is that love is here to stay even into eternity.  So, in this comparison, it looks like as far as tongues are concerned, they will cease when the perfect comes (when we have finished our race and have begun the life where we shall never be sick again, never die or never need to depend on tongues to pray or prophesies to know the will of God in our lives).  Love in comparison will never cease even when the perfect comes.  I hope this helps.
