    Every boy wants to find treasure.And Tom was no different.  One summer day Tom told Huck about his idea.

    "Where can we look for treasure?"asked Huck.

    "It's hidden on islands,under dead trees,but mostly under the floors in haunted(闹鬼的) houses."

    So,one Saturday afternoon Tom and his friend went to look for treasure as the haunted house on Cardiff Hill.It was a quiet and lonely which made the boys feel very frightened.They entered quietly,and explored downstairs.Everything was old,broken and dirty.They threw their tools in a corner and walked upstairs,but there was nothing there.They were just about to go downstairs and start digging when Tom stopped.

    "What is it?"whispered Huck,going white with fright.

    "Keep quiet! There's someone downstairs."

    The boys lay down,looking through the holes in the wooden floor.There were two men downstairs.One was an old Spaniard in a wide sombrero hat and the other was duty and unpleasant﹣looking.

    Tom and Hack shook with fear when they heard the Spaniard speak because they found it was Injun Joe He said,

    "It's time for us to move,partner.What will we do with the 650formtherobbery(抢劫)?""Let'skeep30each and leave the bag here."

    The dirty man went to the fireplace and moved a stone.Then he lifted out a bag full of money and look out some coins.The two boys forgot all their fears when they saw there was real treasure downstairs.

    Then Indian Joe started digging a hole with his knife and the knife hit something.

    "What is it?"asked the other man.

    "It's a box,"said Indian Joe.And he put in his hand and pulled out a handful of gold coins.The other man found the boys'tools,and they soon pulled out the box.

    "Where's thousands of dollars in there,"Said Indian Joe.

    "The Murrell Gang used this area one summer,"said his partner.

    "They most have hidden their money here."

    "What will we do with this,Joe?Will we bury(埋)it again?"

    "No,someone might find it,"said Indian Joe."Let's bury it in the member two den(巢穴)."

    Tom and Huck got up as soon as the two men left.They decided to watch out for the"man in the sombrero"when he came to town and find out where the member two den was.

      【甲】十年春,齐师伐我。公将战,曹刿请见。其乡人曰:“肉食者谋之,又何间焉?”刿曰:“肉 食者鄙,未能远谋。”乃入见。问:“何以战?”公曰:“衣食所安,弗敢专也,必以分人。”对曰:“小惠未徧,民弗从也。”公曰:“牺牲玉帛,弗敢加也,必以信。”对曰:“小信未孚,神弗福也。”公曰:“小大之狱,虽不能察,必以情。”对曰:“忠之属也。可以一战。战则请从。”

       公与之乘,战于长勺。公将鼓之。刿曰:“未可。”齐人三鼓。刿曰:“可矣。”齐师败绩。公将驰之。刿曰:“未可。”下视其辙,登轼而望之,曰:“可矣。”遂逐齐师。

       既克,公问其故。对曰:“夫战,勇气也。一鼓作气,再而衰,三而竭。彼竭我盈,故克之。夫大国,难测也,惧有伏焉。吾视其辙乱,望其旗靡,故逐之。”

      【乙】十三年春,楚屈瑕伐罗,斗伯比送之。还,谓其御曰:“莫敖①必败。举趾②高,心不固矣。”遂见楚子,曰:“必济师。”楚子辞焉。入告夫人邓曼。邓曼曰:“大夫其非众之谓。莫敖狃于蒲骚之役③,将自用也,必小罗。君若不镇抚,其不设备乎!不然,夫岂不知楚师之尽行也?”楚子使人追之,不及。

       莫敖使徇④于师曰:“谏者有刑。”及鄢⑤,乱次以济,遂无次。且不设备。及罗,罗与卢戎两军之,大败之。莫敖缢于荒谷。群帅囚于冶父而听刑。楚子曰:“孤之罪也。”皆免之。
