спишите. выделите корень в однокоренных словах. как-то раз пастухи поймали лисёнка и посадили в пустой амбар. лисица бегала вокруг амбара, пробовала подрыть землю под ним. делать было нечего. посадили лисенка в мешок и отнесли назад в лес, к лисьим норам. с тех пор лиса больше в деревню не приходила.
