The Ant and the Grasshopper（在线收听）

    One cold，frosty day in the middle of winter a colony of ants was busy drying out some grains of corn which had grown damp during the wet autumn weather．A grasshopper，half dead with cold and hunger，came up to one of the ants．“Please give me a grain or two from your store of corn to save my life，”he said faintly．“We worked day and night to get the corn in．Why should I give it to you?”asked the ant crossly．“What on earth were you doing all last summer when you should have been gathering your food？”
    “Oh I didn't have time for things like that，”said the grasshopper．“I was far too busy singing to carry corn about．”
    The ant laughed unkindly．“In that case you sing all winter as far as I am concerned，”he said．And without another word he returned to his work．Plan ahead．You can't rely on other people to look after you．Exercises：
