    柴成务，字宝臣，曹州济阴人也。父自牧，举进士，能诗，至兵部员外郎。成务乾德中京府拔解，太宗素知其名，首荐之，遂中进士甲科，解褐陕州军事推官。改曹、单观察推官，迁大理寺丞。太平兴国五年，转太常丞，充陕西转运副使，赐绯，再迁殿中侍御史。八年，与供奉官葛彦恭使河南，案行遥堤。历知果、苏二州，就为两浙转运使，改户部员外郎、直史馆，赐金紫。入为户部判官、迁本曹郎中。太宗选郎官为少卿监，以成务为光禄少卿。

    俄奉使高丽，远俗尚拘忌，以月日未利拜恩，稽留朝使。成务贻书，往反开谕大体，国人信服，事具《高丽传》。淳化二年，为京东转运使。会宋州河决，成务上言：“河水所经地肥淀，愿免其租税，劝民种艺。”从之。召拜司封郎中、知制诰，赐钱三十万。时吕蒙正为宰相，尝与之联外姻，避嫌辞职，不许。俄与魏庠同知京朝官考课。四年，又与庠同知给事中事，凡制敕有所不便者，许封驳以闻。

    蜀寇平，使峡路安抚，改左谏议大夫、知河中府。时银、夏未宁，蒲津当馈挽之冲，事皆办集，得脱户八百家以附籍。府城街陌颇隘狭，成务曰：“国家承平已久，如车驾临幸，何以驻千乘万骑邪?”乃奏撤民庐以广之。其后祀汾阴，果留跸河中，衢路显敞，咸以为便。

    真宗即位，迁给事中、知梓州。未几代还，又遣知青州，表求俟永熙陵复土毕之任。旋受诏与钱若水等同修《太宗实录》，书成，知扬州。入判尚书刑部，本司小吏倨慢，成务怒而笞之，吏击登闻鼓诉冤，有诏问状。成务叹曰：“忝为长官，杖一胥而被劾，何面目据堂决事邪!”乃求解职。景德初，卒，年七十一。

    成务有词学博闻稽古善谈论好谐笑士人重其文雅然为郡乏廉称时论惜之文集二十卷。成务年六十六始有子，比卒，裁六岁，授奉礼郎，名贻范，后为国子博士。

(节选自《宋史》列传第六十五)

    Do you ever find yourself getting really unhappy for almost no reason? Or suddenly feeling down without knowing why? Going from sadness to anger to joy in a matter of minutes can make many teens feel as though they're losing control. But why is the feeling so common among teens?

    Maybe you're starting a new school and not able to see old friends as much. Getting good grades or wanting to be better in sports or other activities can be a concern (关注) for many teens.

    Being accepted by friends is important. Teens also may notice, for the first time, a sense of distance from parents and family. You may feel you want to be on your own and make your own decisions, but it can also seem a bit lonely at times.

    Another important cause for mood swings is biology. When puberty (青春期) begins, the body starts producing hormones (荷尔蒙). These hormones cause physical changes in the body. But in some people, they also seem to cause emotional (情绪的) changes.

    Here are some things you can do that might make those bad moods a bit easier to deal with.

    Recognize you're not alone. Although not every teen experiences mood changes to the same degree, they are common.

    Talk to people you trust. Friends can help each other by realizing that they're not alone in their feelings. Talking to parents is important, too. Parents can share their own experiences dealing with bad moods. Teachers are often good resources and a doctor can help to answer questions about development.

    Get enough sleep. Though it can be hard to find enough time, getting enough rest is very important. Being tired can lead to more sadness.

    Create. Taking part in some kinds of activities, like building something out of wood, or starting an art or music piece. Writing can help you organize and express your thoughts and feelings. Get your thoughts on paper. Do the same thing with paint, music, or other art forms. Put your feelings into your artwork.
