阅读下面的文言文,完成问题。

    安守忠,并州晋阳人。晋天福八年,以守忠为牙内指挥使,领绣州刺史。周显德四年春,改鞍辔库使。会淮南初下命守忠驰往宣谕时藩臣骄蹇遇朝使多简傲守忠抗以正礼无所辱命。未几,改卫州刺史。

    宋初,入为左卫将军。蜀平,太祖知远俗苦苛虐,南郑为走集之地,故特命守忠知兴元府以抚绥之。四年,改汉州刺史。时寇难甫平,使车旁午,公帑不足,守忠出私钱以给用。每遣使,太祖必戒之曰:"安守忠在蜀,能律己以正,汝行见之,当效其为人也。"开宝五年,知辽州。民有阴召并州寇谋内应者,事泄,守忠悉斩以徇。九年,命将征太原,守忠受诏与孙晏宣由辽州入,既而与路罗寨监押马继恩遇,乃相与会兵入贼境,燔寨四十余,获牛羊数千。

    雍熙二年,改知易州,徙夏州。每西戎犯边,战无不捷。淳化二年,知雄州。方与僚佐宴饮,有军校谋变,擐甲及阍,阍者仓卒入白。守忠言笑自若,徐顾坐客曰:"此辈酒狂尔,擒之可也。"人服其量焉。明年,加耀州观察使,兼判雄州。未几,召还,条陈边事,敷奏称旨,赐钱五百万。五年,又知沧州。至道初,移雄州。三年,复知沧州。拜感德军节度观察留后,徙宋州,兼制置营田使。威德兼著,吏民不忍其去。咸平三年,入觐,遣还未行,暴卒,年六十九,赠太尉。

    守忠谨悫淡薄,为治简静。太祖居藩日,素相厚善,及受禅后,每优任之,守忠处之益谦。从征太原,多与谋略,人罕知之者。所至藩郡,乐施予,丰宴犒,且喜与士大夫游从,故时论多与之。

Four Ways to Give Truly Meaningful Gifts

    Buying someone you love a gift that expresses your truest feelings isn't always easy. But when you get it right, the joy they show is worth it. ____

    Listen up.

    While you may think it's a great idea to surprise someone by giving them something you think is meaningful, it's best to get them exactly what they have told you. For example, you heard friends say they wanted the newest bike but you bought them a gym membership instead. ____ So get them what they've specially asked for.

    ____

    In the spirit of showing love, we might go big. However, we may not be thinking of what really makes the person happy. You might think buying your father the latest TV is perfect, but then when you get it home, it lights up the living room like a stadium and is totally wrong for the space. So think smart.

    Keep it open.

    Many of us may consider giving cash impersonal(没人情味的). But this may save you some concern. The receiver can be allowed to choose whatever they want. In a recent survey of over 7,000 Black Friday shoppers, 39 percent said the receiver they were shopping for was “picky(挑剔)”. ____

    Create an experience.

    Visit websites where you can get the latest tickets for a play, buy a surf lesson, or even something unexpected like a flight lesson. ____ For example, if your kids are into NASCAR, just imagine the look on their faces when you score them a ride at a race car driving school. So give them a time that they will remember to heart.

A. Ignore the size.

B. Go for something big.

C. Well, that was the wrong move.

D .If possible, cut down the cost of the gifts.

E. These are things that can create a lasting memory.

F. Here's how to discover a gift your receiver will love.

G. So save yourself the second guess and give cash instead.
