中华历史上,产生于农耕文化的宗族,是以血缘的亲疏关系聚集起来的地缘与血缘共同体,构成了乡村社会结构的重要基础。
在中国漫长的历史时期,乡村共同体的内聚性、稳定性和连续性是中国社会凝聚与稳固的坚实基座,是中华文明绵延不绝的重要根基。
在农业生产中,土地、生产方式、人口规模、组织形式四要素构成反应链,成为农耕文明的重要基底。
土地的状况决定了适宜种植的作物种类和基本的耕作方式。
生产方式是粗放还是精细、是否兴修水利等,对亩产量有着决定性影响,进而决定人口规模。
一定规模的人口以何种方式组织生产,不仅影响着具体的生产方式,还奠定了社会结构的基础。
在耕种大面积土地以及修建大型水利工程时,需要大量劳动力,为了协调生产,对人群的组织形式也会提出更高的要求。
以血缘纽带将人群组织在一起,无疑是最为自然的方式。
于是宗族便理所当然地成为农耕时代基层的社会组织,承担着生产与管理的基本社会职责。
土地是农业生产最为关键的要素,掌握了土地管理权,实际上也就具备了对生产与生活的支配权。
因此,宗族在实质上就成为农耕文化的关键性因素。
宗族的人伦秩序与道德规范建立起人与人之间的和睦关系。
就宗族内部成员而言,宗族建立了具有相同血缘的人与人之间的纽带,使其不至离散,具有一定的内聚力。
宗族的内聚功能,在族约、家训、祠规等家族文献中,以尊祖、孝亲、敬长、睦族等观念体现出来。
祭祖仪式加强了共同的祖先认同与血缘认同,强化了内部团结和内部整合。
编修族谱为家族成员提供了由文字铭刻的共同祖先记忆。
作为宗族集体财产的族田主要分为祭田、义田和义学田三种类型,祭田收入主要用于祭祀祖先,置义田“以赡宗族之孤寡贫困者”,义学田则为义学提供经费。
就宗族与外部人群而言,宗族为乡里社会提供地方防卫、兴修水利等公共设施,并积极处理乡里冲突,建立宗族与乡里之间的秩序。

儒家文化中蕴合着大量的生态美学思想,发掘这些生态美学思想的丰富意蕴,对当代生态文明社会构建和生态家园建设具有重要意义。
儒家在看待人与自然的关系方面极具先见之明,其中“天人合一”是其最有代表性的观点之一。
儒家的生态自然观念注重人的作用,强调人的主观能动性,追求人与天地自然万物和谐相处。
儒家先贤中特别重视人的主观能动性的是荀子,他说“天行有常,不为尧存,不为桀亡”(《荀子·天论》);但是人如果能在遵守自然规律的前提下,“制天命而用之”,“应时而使之”,就能在不损害自然的情况下为人类自己谋福利,从而实现人与自然万物的和谐共处。
到汉代时,董仲舒进一步阐述了“天人合一”的思想。
他指出,人与自然是一个不可分割的整体,“天地人,万物之本也。
天生之,地养之,人成之”,“三者相为手足,合以成体,不可一无也"(《春秋繁露·立元神》)。
宋代张载说:"儒者则因明致诚,因诚致明,故天人合一。
"(《正蒙·乾称》)明清之际的王夫之发展完善了“天人合一”思想,他认为天、地、人三者是一个和谐统一的整体。
“仁”的学说是儒家思想的核心,历代儒家先贤都对其有继承和发展。
董仲舒曾说:“质于爱民,以下至于鸟兽昆虫莫不爱。

Some of these expressions are commonly used for many years. Others are popular for just a short time. One such American expression is “Where’s the beef?” It is used when something is not as good as it is said to be. In the early 1980s “Where’s the beef?” was one of the most popular expressions in the United States. It seemed as if everyone was using it at the time.Beef, of course, is the meat from a cow, and food is more popular in America than a hamburger made from beef. In the 1960s a businessman named Ray began building small restaurants that sold hamburgers at a low price. Ray called this “McDonald’s”. Ray became one of the richest businessmen at last in America.Other business people watched his success. Some of them opened their own hamburger restaurants. One company(公司) called “Wendy’s” said its hamburgers were bigger than those sold by McDonald’s or anyone else. The Wendy’s Company began to use the expression “Where’s the beef?” to make people know that Wendy’s hamburgers were the biggest. The Wendy’s television advertisement(广告) showed three old women eating hamburgers. The bread that covered the meat was very big, but inside there was only a bit of meat. One of the women said she would not eat a hamburger with such a little piece of beef. “Where’s the beef?” she shouted in a funny way. The advertisement for Wendy’s hamburger restaurants was a success. As we said, it seemed everyone began using the expression “Where’s the beef?”1.The expression “Where’s the beef?” is used when.A.someone can’t find the beef at allB.someone isn’t satisfied with the beefC.something is better than it is said to beD.something is not as good as it is said to be2.“Where’s the beef?” was one of the most popular expressions in ________ in the early 1980s.A.Britain B.America C.India D.Australia3.The Wendy’s Company used the expression “Where’s the beef?” in order to.A.show Wendy’s hamburgers were the biggest.B.make people know where they could find the beefC.let people notice the bread that covered the meat was bigD.compare its hamburgers with those sold by McDonald’s4.This passage mainly tells us .A.two famous companies B.a rich businessmanC.a popular expression D.a television advertisementF18、Playing video games can be a fun way to spend time with friends. In some schools, teachers use games like Minecraft to encourage teamwork and communication.But for some players, gaming is an unhealthy habit. They stay up late playing games. They do little or no homework. They give up other hobbies and pay little attention to their families and friends. The video-game world seems a friendlier place than the real one.Mental(精神的)health experts(专家)hav e taken notice. The World Health Organization(WHO) listed “ gaming disorder(电玩失调症)” as a disease(疾病)last year. A person may have the disorder if gaming has done harm to his or her relationships with family and friends. and if it has influenced his or her daily activities.Not all experts agree that over-gaming should be called a disorder. They say people who spend too much time on video games may develop other mental health problems. These should be treated first.Others think WHO did the right thing. Clifford Sussman is a doctor who treats gaming addiction (瘾). He says those kids often get angry easily and it makes everything difficult for them to complete, like schoolwork.Sussman advises tracking(跟球)how long you play. He says you should take at least an hour-long break after every hour of play. The brain needs time to recover(恢复).Young gamers who think they might have a problem should ask an ad(成年人)for help.Sussman suggests you firstanswer a simple question: “Are you in control, or is the game in control?”1.The writer develops his idea in Paragraph 2 by .A.giving some examples B.using an expert ’s opinionC.describing his personal habits D.introducing the result of a survey2.The underlined word " it " in Paragraph 3 refers to “”.A.gaming B.a diseaseC.gaming disorder D.a video game3.According to Sussman, kids with gaming addiction .A.have grown in number these yearsB.should be treated as early as possibleC.often have trouble doing lots of thingsD.may have different mental health problems4.By answering Sussman s question, we may knowA.what gaming addiction is B.if we have gaming addictionC.how to fight gaming addiction D.why to fight gaming addictionⅤ.书面表达19、垃圾污染环境并危害人类健康。
