杨伯仁字安道，伯雄之弟也。天性孝友，读书一过成诵。登皇统九年进士第，事亲不求调。天德二年，除应奉翰林文字。初名伯英，避太子光英讳，改今名。

海陵尝夜召赋诗，传趣甚亟，未二鼓奏十咏，海陵喜，解衣赐之。海陵射鸟，伯仁献《获乌诗》以讽。丁父忧，起复，赐金带袭衣，及赐白金以奉母，改左拾遗。进士吕忠翰廷试已在第一，未唱名，海陵以忠翰程文示伯仁，问其优劣，伯仁对曰：“当在优等。”海陵曰：“此今试状元也。”伯仁自以知忠翰姓名在第一，遂宿谏省，俟唱名乃出 ， 海陵嘉其慎密。

孟宗献发解第一，伯仁读其程文，称之：“此人当成大名。”是岁，宗献府试、省试、廷试皆第一，号“孟四元”，时论以为知文。故事，状元官从七品，阶承务郎，世宗以宗献独异等，与从六品，阶授奉直大夫。

改著作郎。居母丧，服除 ， 调镇西节度副使。入为起居注兼左拾遗，上书论时务六事。改大名少尹。郡中豪民横恣甚，莫可制，伯仁穷竟渠党，四境帖然。谳馆陶大辟 ， 得其冤状，馆陶人为立祠。除滨州刺史。郡俗有遣奴出亡，捕之以规赏者，伯仁至，责其主而杖杀其奴。如是者数辈，其弊遂止。

伯仁久在翰林，文词典丽，上曰：“自韩昉、张钧后，则有翟永固，近日则张景仁、郑子聃，今则伯仁而已，其次未见能文者。吕忠翰草《降海陵庶人诏》，点窜再四终不能尽朕意，状元虽以词赋甲天下，至于辞命未必皆能。凡进士可令补外，考其能文者召用之。”不数月，兼左谏议大夫，俄兼太常卿。

大臣举可修起居注者数人，上以伯仁领之。从幸上京伯仁多病至临潢地寒因感疾还中都明年上还幸中都遣使劳问赐以丹剂是岁，卒。

    It's no surprise that sports can greatly benefit a child physically, psychologically, and socially. A 2008 Women's Sports Foundation Research Report concluded that children's athletic participation is also associated with increased levels of family satisfaction, great achievement in study, and an overall better quality of life for children. And a study published in last month's American Journal of Preventive Medicine showed that kids who are active at age 5 wind up with less body fat at ages 8 and 11.

    But one hotly debated discussion focuses on the kinds of sports kids should play, with parents mistakenly thinking, "Lizzie is so quiet, we should let her join in basketball and soccer to try to get her to open up." But increasingly, experts are suggesting the healthier instinct (直觉) might be, "Lizzie is so quiet. Maybe we should see if she likes playing with a big team like softball or if she likes ballet or swimming, where she can work more on her own terms."

    “Participation in any sport is going to provide kids with life skills—the ability to focus and to concentrate, the ability to handle pressure in tough situations, the ability to stay calm when things aren't going just right,'' explains Orlando-based youth sports psychology expert Patrick Cohn. Those lessons will carry over into future, non-sports attempts.

    Team sports certainly offer benefits not as easily obtained via individual activities, as players leant how to communicate and work with others, and there's the potential to develop leadership abilities. Team sports also help kids develop their social identity. Our sense of worth is developed through what we achieve and a sense of belonging.

    Individual sports offer unique advantages, too, like developing a child's sense of independence. “Hero, you don't depend upon teammates," says Cohn. "You take full responsibility, whether you do well or perform poorly." Many of Cohn's young clients complain about pressure from team mates or coaches to make zero mistakes or carry more of the team than they may want to; these kids may enjoy a solo sport like tennis or gymnastics.

    Individual activities keep kids away from comparing themselves to the best players on the team, a habit that does little to help confidence levels. Instead, it encourages them to compare their skills to their own past performances. With individual sports like swimming or track, it's easier for the child to participate on his own, at his leisure(闲暇), without having to round up a bunch of like-minded peers.

    Above all, while some children enjoy the excitement of competition, others are more likely to benefit from the freedom of individual sports, and finding the right balance can be necessary for children's enjoyment. What parents think is encouragement, children often consider as pressure. So try to understand what they want from sports.

    While engineers have made out fantastic products for sitting still—Munchery instead of walking to lunch, Uber instead of walking to the bus stop—services to make you move have been less appealing for consumers.

    Fitbit's stock price fell 18% after they announced their latest Apple Watch-like product named Fitbit Force. And new data suggests that, for the first time, death rates for large parts of the American population are rising, with signs pointing to inactivity and weight gain as the reasons. Our digital lifestyles and desk-based workplaces are contributing to serious health problems and could be shortening our lives, wellness firms want us to believe.

    Northrup, president and co-founder of the connected exercise device TAO-Wellness, was in Las Vegas to promote TAO's small device that encourages exercises. He lifts the device, about the size of an apple, and says workplaces should start encouraging on-site exercise.

    Nick Mokey, the managing editor of Digital Trends, agrees. “I hate to break it to you, a room full of people sitting down, but sitting is killing you,” he says to the audience. They shift in their seats.

    In the health section of the Sands Exposition Hall, people are selling devices made by LifeSpan Fitness. They say they're the largest seller of treadmill（跑步机） desks in the US. At the center of their exhibition area is a Bike Desk, which looks like three gym bikes attached to a table. That's for people who just want to sit and enjoy conversation.

    Treadmill desk-related shame is their biggest obstacle, they say when LifeSpan installs two in opposite ends of the same building, neither tends to get used. If the company installs two next to each other, people will use them. “You don't want to be so noticeable, especially at work,” company spokesman James Lowe says. What's more, what if we get sweaty using a treadmill in the office?

材料一

作为我国民事法律的集大成者，民法典是新中国成立以来第一部以“法典”命名的法 律，也是第一部直接以“民”命名的法典。以“法典”命名，表明凡是纳入民法典的规则，都具有基础性、典范性的特点；以“民”命名，说明民法典把人民愿望置于首位，充分反映了人民的利益诉求。此次民法典草案亮点很多，最大的亮点就是为民立法、以民为本，最大化地谋求人民的利益。民法典的立法宗旨和目的就是充分反映人民群众的意愿，保障 私权，维护广大人民群众的利益。“人民的福祉是最高的法律。”新中国成立后，特别是改革开放以来，对民事权利的保护逐渐加强。今天，我们之所以要颁行民法典，是因为进入新时代，人民群众不仅对物质文化生活的需求提高，而且在民主、法治、公平、正义、安全、环境等方面的需求日益增长，对民事权利的保障提出了更高的要求。在新的历史时期，保障人民更加广泛的民事权利十分重要。民法典既确认了个人享有各项具体民事权利，明确了这些权利的具体内容和边界，又保护个人能够正常行使和主张权利，免受他人不法侵害。

材料二

近日，十三届全国人大三次会议今天表决通过了《民法典》，将从2021年1月1日 起实施。每个人的每项权利在每时每刻都受到民法典的保护，出台民法典，标志着我国依法保护民事权利将进入全新的“民法典时代”。《民法典》实施后，我国现行婚姻法、继承法、民法通则、收养法、担保法、合同法、物权法、侵权责任法、民法总则将同时废止。在民法典中，“平等”与“保护”是贯穿始终的立法精神。如强化对胎儿利益的保护，降低限制民事行为能力的年龄，宣示对弱势群体的特殊保护，规定成年监护制度，增设专章规定居住权，以满足特定人群的居住需求等。此外，民法典适应时代发展的需要，回应了 当今社会的现实需求。例如，民法典草案单独设立人格权编，突出保护公民的隐私权、肖像权等重要权利，不仅是我国民事立法的一次重大创新，更蕴含着对人民权利的充分尊重 和保护、针对互联网和大数据等技术发展带来的侵害个人信息现象，民法典规定了个人信息的保护规则，还首次将数据、网络虚拟财产纳入保护范围。

绝大部分国家都有民法，但有民法典的并不多。代表委员们表示，编纂中国人自己的 民法典，必须扎根中国土壤、紧扣时代脉搏。民法典突出对绿水青山蓝天的保护，将绿色原则确立为民法的基本原则；新增的保理合同相关规定，解决企业融资问题，优化营商环境……陈晶莹代表说，民法典草案紧随社会进步、经济发展，具有很强的前瞻性和开放性。“中国人在道德共识、价值理念和文化象征等精神层面的特性，都通过民法典草案浇筑到 具体的制度和规则中，具有鲜明的中国特色。”全国政协委员、北京金台律师事务所主任皮剑龙说。在一些代表委员看来，民法典草案通过实施后，将成为中国特色社会主义法治体系的重要支柱，也为未来相关民商事法律规范的制定提供标准。孙宪忠代表告诉记者，民法典草案已为一些民商事活动领域留出了充分的立法空间。“如在知识产权等方面，相信民法典将为今后特定领域的立法打下基础、提供便利。”他说。民法历史悠远，中国民法典助力开创未来。李亚兰代表说，民法典立法突出时代特点、反映人民意愿，具备与时俱进的立法态度、实事求是的科学精神，必将为这个奋进的时代提供更为完备的法治保障。

李密

臣密言：臣以险衅，夙遭闵凶。生孩六月，慈父见背，行年四岁，舅夺母志，祖母刘悯臣孤弱，躬亲抚养。臣少多疾病，九岁不行，零丁孤苦，至于成立。既无伯叔，终鲜兄弟：门衰祚薄，晚有儿息。外无期功强近之亲，内无应门五尺之僮、茕茕子立，形影相吊 ， 而刘夙婴疾病，常在床蓐；臣侍汤药，未曾废离，

逮奉圣朝，沐浴清化。前太守臣達察臣孝廉，后刺史臣荣举臣秀才。臣以供养无主，辞不赴命。诏书特下，拜臣郎中 ， 寻蒙国恩，除臣洗马。猥以微贱，当侍东宫，非臣陨首所能上报、臣具以表闻，辞不就职，诏书切峻，责臣逍慢， 郡县逼迫，催臣上道：州司临门，急子星火、臣欲奉诏奔驰，则刘病日岛； 欲苟顺私情， 则告诉不许： 臣之进退，实为狼狈。

伏惟圣朝以孝治天下，凡在故老，犹蒙矜育，况臣孤苦，特为尤甚。且臣少仕伪朝，历职郎暑，本图宦达，不矜名节。今臣亡国贱俘，至微至陋，过蒙拔權，宠命优湿，岂敢盘柜，有所希算！但以刘日薄西山，气息奄奄，人命危浅，朝不虑夕。 臣无祖母无以至今日祖母无臣无以终余年母孙二人更相为命是以区区不能废远。

臣密今年四十有四，祖母今年九十有六，是臣尽节于座下之日长，报养刘之日短也，乌鸟私情，愿乞终养。臣之辛苦，非独蜀之人士及二州牧伯所见明知，皇天后土，实所共鉴， 愿座下矜悯愚诚，听臣微志，庶刘侥幸，保卒余年，臣生当陨首，死当结草。臣不胜犬马怖惧之情，谨拜表以闻。

同温同压下，等质量的O₂和CO₂相比较，下列叙述正确的是（    ）
