    I was 10 the year my cousin Marley's parents gave her a painful Christmas surprise: they were getting a divorce(离婚). My aunt went to California, but my uncle decided to get her back. There was one matter: where to put his young daughter. Luckily, my mother loved Marley, giving her more attention than her family ever did.

    On that Christmas Eve, my cousin arrived on our doorstep carrying an old blue suitcase. Before she stepped inside, Marley said, “It doesn't matter. When my parents come back, we'll have a bigger Christmas than this.”

    Late on the night Marley arrived, my mom came into my room, her arms filled with packages.I knew they were my Christmas presents. “I know how you love surprises but we have to decide which ones to give to Marley.”

    My mother carefully opened the gifts. Wow! I saw ice skates, red leather gloves and a dollhouse. The last present was the music box we'd asked the lady at the local store to take down and play for us over and over again.

    “Which ones?” my mother asked. “She can have the ice skates,” I said reluctantly(勉强地). “That's good,” my mother said. She began to tape the packages up again. Then she stopped and asked, “Are you sure about these?” At that moment, I realized she expected more from me than I had already given. So I gave her the music box, too, and ___________. The next morning, Marley's eyes were resolute(坚定的). She expected nothing and wanted us to know she didn't care. But when she saw her name on the biggest box, she couldn't hide her excitement. I thought my happiness would be cut in half. Instead it was doubled.

    Over the last 40 years, Marley and I have grown apart(分离的). But the love we felt for each other that day still remains. Today Marley says, “They were the best presents I ever got.

    王罴,字熊罴,京兆霸城人。罴质直木强,处物平当,州闾敬惮之。魏太和中,除殿中将军,稍迁雍州别驾,清廉疾恶,励精公事。先是南岐、东益氐羌反叛,乃拜罴冠军将军,镇凉州,讨平诸贼。还,授西河内使,辞不拜。时人谓曰:“西河大邦,奉禄优厚,何为致辞?”罴曰:“京洛材木,尽出西河,朝贵营地并第宅者,皆有求假,如其私办,即力所不堪,若科发人间,又违宪法,以此致辞耳。”粱复遣曹义宗围荆州,堰水灌城,不没者数版。时既内外多虞,未遑救援,乃遗罴铁券,云城全当授本州刺史。城中粮尽,罴乃煮粥与将士均分食之。每出战,常不擐甲胄,屡经战阵,亦不被伤。弥历三年,义宗方退,齐神武率军进潼关,人怀危惧,罴劝勱交士,众心乃安。尝修城未毕,梯在城外。神武遣韩轨、司马子如从河东宵济袭罴,罴不觉。比晓,轨众已乘梯人城。罴尚卧未起,闻阁外汹汹有声,便袒身露髻徒跣,持一白棒,大呼而 出,谓曰:“老罴当道卧,貉子那得过!”敌见,惊退。逐至东门,左右稍集,合战破之。尝有台使至,罴为设食,使乃裂去薄饼缘。罴曰耕种收获其功已深舂爨造成用力不少尔之选择当是未饥命左右撤去之使者愕然大惭。又客与罴食瓜,客削瓜皮,侵肉稍厚,罴意嫌之。及瓜皮落地,乃引手就地取而食之。客甚愧色。每至享会,自秤量酒肉,分给将士。时人尚其均平,嗤其鄙碎,罴举动率情,不为巧诈,凡所经处,虽无当时功迹,咸去乃见思。罴安于贫素,不营生业,身死之日,家贫甚罄,当时伏其清洁。卒于官,赠太尉、都尉、相冀等十州刺史,谥曰忠。
