二根据短文内容选择合适的答案英语乌鸦喝水篇

:有一只乌鸦不好看，但特别聪明，智慧过人。一天，它干完活又累又渴，真想喝水。忽然，它看一只大水罐，满心欢喜。它飞到水罐旁，一看罐里的水不多了，嘴探进去也喝不到，怎么办呢？它使劲地用身体撞水罐，又用翅膀推水罐，想把水罐弄倒，好喝水。可是水罐又大又重，它的力量太小了，弄不倒这罐子。忽然，它急中生智，可以叼些石子放到罐里，石子多了，罐子里的水不就升高了吗？这么想，就这么做了，它不厌其烦地一块一块地用嘴叼石子，功夫不负用功的乌鸦，终于放了很多石子，水上升了，它就喝到了水。它痛痛快快地喝了个够，解了渴。这是原文:ACrow,half-deadwiththirst,cameuponaPitcherwhichhadoncebeenfullofwater;butwhenTHECrowputitsbeakintothemouthofthePitcherhefoundthatonlyverylittlewaterwasleftinit,andthathecouldnotreachfarenoughdowntogetatit.Hetried,andhetried,butatlasthadtogiveupindespair.Thenathoughtcametohim,andhetookapebbleanddroppeditintothePitcher.ThenhetookanotherpebbleanddroppeditintothePitcher.ThenhetookanotherpebbleanddroppedthatintothePitcher.ThenhetookanotherpebbleanddroppedthatintothePitcher.ThenhetookanotherpebbleanddroppedthatintothePitcher.ThenhetookanotherpebbleanddroppedthatintothePitcher.Atlast,atlast,hesawthewatermountupnearhim,andaftercastinginafewmorepebbleshewasabletoquenchhisthirstandsavehislife.
