唐代文学繁荣的原因很多，有些时代条件是难以复制的.但之所以能达到高峰，也有文人们的自觉努力，其中有些因素仍然值得当代文艺工作者思考.一代文人为时代而创作的使命感是文学高峰形成的前提。

唐代文人们在不同时期都能将个人和国家命运联系在一起，有为时代而创作的责任感。

例如初盛唐是走向兴盛的时期，文人们对时代和人生进行自觉的思考，将欣逢盛世的自豪感和自信心转化为积极进取的精神和乐观的情怀，创作出充分体现时代风貌的优秀作品.李白在《古风》其一中写道:“圣代复元古,垂衣贵清真。

群才属休明，乘运共跃鳞。

文质相炳焕,众星罗秋旻.我志在删述，垂辉映千春……"他认为开元年间复兴了尧舜的太平之世，才子们纷纷乘此时运,各展才能,写出文质兼备的诗歌,自己更是希望著述照耀千秋。

而在安史之乱中,杜甫处于家国兴亡的危急关头，则写下大量忧国忧民的传世名作。

中唐时期，社会危机重重，白居易提出“文章合为时而著，歌诗合为事而作"，以许多讽喻诗广泛触及中唐各种政治问题反映现实的深度和力度都是后人所不能企及的。

文学高峰的形成与文学风气、文学形式大力变革有关.以诗歌来说，齐梁陈隋时期诗风浮靡,唐朝从开国之初就将政治革新和文风革新联系在一起。

从初唐到盛唐，诗歌经历过三次重要革新。

其主要方向是提倡诗歌文质兼备，发扬比兴寄托的风雅传统，肃清浮华绮丽的文风.初唐四杰提出要廓清“积年绮碎"，强调刚健的气骨和宏博的气象。

继四杰之后，陈子昂标举风雅兴寄和建安气骨，批判齐梁诗的“彩丽竞繁”。

到初盛唐之交，张说和张九龄进一步提出作文要风骨和文采并重，鼓励多样化的内容和风格,并提出以“天然壮丽"为主的审美理想。

经过这三次革新，建安气骨在开元中为诗人们广泛接受，以建安气骨为核心的“盛唐气象”形成.唐代诗人善于提炼具有普遍性的人情，表现人生共同感受,使之达到接近生活哲理的高度，因而尤能引起后人广泛的共鸣。

2021年秋四川省棠湖中学高一期末统考模拟试卷语文试题时量：150分钟分值：150分第一卷阅读题〔70分〕一、现代文阅读〔36分〕〔一〕阐述类文本阅读〔9分，每题3分〕阅读下面的文字，完成1~3题。

仁与孝在孔子思想体系中具有重要的地位。

“仁〞作为儒学核心理念，结合时代需要演化为“仁德〞〔完美的个人修养〕、“仁爱〞〔理想的人际关系〕、“仁政〞〔完善的政治统治〕思想，形成了完备的“仁学〞体系；“孝〞作为孔子思想的另一个核心概念，同时又贯穿于“仁德〞“仁爱〞“仁政〞之中。

孔子使孝由源出的宗教意义转化为纯粹的伦理意义，从宗教道德传统转化为个人道德修养及家族道德原那么。

孝成为一切高尚道德的内在根据，在详细践行过程中，奉行孝道成为建立各种美德的起点；理论孝道的过程就是仁德不断扩大开展，进而实现孝的目的，同时进达仁德境界的过程。

孔子提出：“孝弟也者，其为仁之本与！〞〔?论语•学而?〕孝悌是仁德的根底，在家里行孝尽悌就是仁德培养的开场，是达仁的有效途径，从而实现“修己以安人，修己以安百姓〞的境地，最终到达仁德兼善天下的目的。

孔子的仁强调人与人相处的根本原那么是爱人。

“樊迟问仁。

子曰：爱人。

〞〔?论语•颜渊?〕孔子要求人们用博大的胸怀去爱人，发自内心深处的爱亲之情成了仁的根本内容。

对父母的亲亲之爱即“孝〞，就自然成为仁爱的起点。

孝与仁的根本内涵是一致的，百姓通过对父母的亲情之爱推己及人，彰显个人对社会、国家的责任和担当，不断追求仁爱的最高目的。

孔子以“爱人〞答复樊迟，意在强调家庭是人际关系的起点，爱从家人开场，进一步推扩到爱别人爱万物爱万民，进达仁爱境界。

孔子希望通过孝建立起良好的家庭秩序，从最根本的亲亲之爱入手，通过发自内心深处爱的情感表达，到达博施于民的仁爱大道，实现家庭和睦、社会安定、人民和谐。

孔子从家庭内部父子、兄弟之间的自然“亲亲〞出发，将孝的功能推扩到社会和政治层面，试图较为圆融地和解家庭、社会和国家关系。

Cooksey had left the engine running and the door unlocked.“When I saw my truck door open, I was like, ‘Oh my God, what am I going to tell my wife?’” Cooksey said.His son, Larry, was sitting in the back seat. “As soon as he opened the door, I got frightened,” said Larry. “So I pulled out the gun and pointed it to his head.”This was enough to make the carjacker think twice and he jumped out of the truck to try another car. Parked beside Cooksey’s truck was Kyle Sparling’s black Trailblazer. He too had left the engine running as he went into the store. The man got in Sparling’s SUV and took of f.“I didn’t know what to think, I just kind of ran outside and watched him,” said Sparling.As the man sped off, Cooksey told Sparling to get into his truck and the two men began to run after him. The icy winter conditions made the driving difficult, but the pair followed at a safe distance as the carjacker drove in a “Z” way. After a few miles, the carjacker knocked into the sign of a local business, American Tool and Party Rental. Cooksey and Sparling called police to the place.The police put 32-year-ol d Ollie Dunn into prison.

The HR manager interviewed him and then watched him cleaning the floor as a test.“You are employed,” he said. “Give me your e-mail address and I’ll send you the application to fill in, as well as date when you may start.”The man replied, “But I don’t have a computer, neither an e-mail.”“I’m sorry,” said the HR manager. “If you don’t have an e-mail, that means you do not exist. And a person who doesn’t exist cannot have the job.”The man left with no hope at all. With only ten dollars in his pocket, he decided to go to the supermarket and buy 10kg tomatoes. He then sold the tomatoes from door to door. In less than two hours, he succeeded to double his capital. He repeated the operation three times, and returned home happily with 60 dollars.The man realized that he could survive in this way, and started to go every day early, and return late.

They are those adults who still live at home and are neither working nor studying. But the problem is not limited to Spain. It is a worldwide problem.In Italy, they are known as “bamboccioni” or big babies. There nearly 60 percent of18-34-year-old adults still live in their parents’ home, up from almost 50 percent since 1983. Once kept there by the love for their mama’s home-cooked food, the economic crisis（经济危机）has seen a rise in adults left unable to hold down a steady job or afford a home of their own. Last year, an Italian government minister admitted that his mother washed his clothes and made the bed for him until he was 30. He demanded a law forcing young Italians to leave their parents’ home at 18 to stop them becoming hopelessly dependent on their parents.In the UK, the government has made the term NEETS---not in employment, education or training for these children. In England alone the percent of NEETS aged 19-24 surged to 18.8 percent of the age group-in the last quarter of 2010, up 1.4 percent on the same period a year before. The number of British men in their 20s living with their parents has risen from 59 percent to 80 percent in the past 15 years, while the number of women has risen from 41percent to 50 percent. The average age of the first-time house buyers is now 38.In the US, the problem is known as the “full nest syndrome（综合症）”. Adults there areleft struggling to support adult children who have stayed at home with student debts and facing few job opportunities in a weak economy.

Take the time now to review the following safety tips, and your family will be prepared in time of a fire in your home:16．An escape plan can help every member of a family get out of a burning house. The idea is to get outside quickly and safely. 17．So it is important to learn and remember the different ways out of your home.Stay lowIf you can see smoke in the house, stay low to the ground as you make your way to the exit. 18．You will breathe less smoke if you stay to the ground. Smoke naturally rises, so if there is smoke while you are using your escape route，staying low means you can crawl (爬) undermost of it.What if y ou can’t get out right away?If you can’t get out fast because fire or smoke is stopping an escape route, you will want to yell for help. You can do this from an open window or call 911 if you have a phone with you. 19．Then, firefighters will have a hard time finding you. The sooner they find you, the sooner you both can get out.If your clothes catch fire, what should you do?Your clothes could catch fire during a fire or by accident if you step too close to a candle. If this happens, don’t run! Instead, stop, drop to the ground, cover your face with your hands, and roll. This will cut off the air and put out the flames. 20．A．An easy way to remember this is: Stop, Drop, and Roll!B．Smoke from a fire can make it hard to see where things are.C．Preventing fires is in the first place!D．Know your way outE.They will help prepare you for what you need to do in case of a fire.F.Even if you are scared, never hide under the bed or in a closet.G.In a fire, smoke and poisonous (有毒的) air hurt more people, than the actual flames (火焰) do.三、完形填空The year my dad turned 80, my brother and I decided to throw a surprise party for him.
