Over years, I've been teaching kids about a simple but powerful concept-the ant philosophy(哲学)．They have an amazing four-part philosophy．First, ants never         ．If they're headed somewhere and you try to stop them, they'll look for another         ．Second, ants think about winter and summer．That’s an important          You can't be so naïve(幼稚的)as to think summer will last forever．So ants are gathering in their winter           in the middle of summer．Think ahead．The third part is that ants think summer all winter．During the winter, they         themselves, "This won't last long; we'll soon be out of here．" They can't           to get out．Last, how much will an ant gather during the summer to prepare for the winter? All that it          can．What a great philosophy to have—the ant philosophy: never give up, look ahead, stay        and do all you can．
