在明代中后期,手工业和商业有了较大发展。
随着市场的发展壮大,从农村流入城镇的 人口日益增多。
城镇生活不同于农村,农民习惯于日出而作,日入而息,男耕女织,各管各的。
城镇居民相对地减少了对土地的依附,人际关系更紧密,人的 自主意识也变强。
这一时 期,文化领域出现了以王学左派为代表的“异端”思想,许多剧作家受此影响,更多地思考 戏曲应如何针砭现实,促进社会进步。
随着市场发展,城镇居民生活有余暇,他们需要丰富多彩的休闲娱乐方式。
人民群众对 戏曲的热情,使许多具有高度文化修养的诗人积极参与戏曲创作,甚至自操檀板,粉墨登场。
这一切为明清戏曲经典作品的涌现创造了良好条件。
由明入清,以王夫之、黄宗羲为代表的知识分子,经历国破家亡,转而更多地思考社会现实问题,力图借鉴兴亡教训。
在这个大变动的时代,讲求情与理合一的思潮让进步剧作家 们更多地面对社会现实,同情人民大众,反思历史得失。
时代的呼唤,社会的变革,正是推动明清戏曲创作走向繁荣的前提。
明清一些戏曲作品能成为经典,是因为其创作者不片面追求“票房价值”。
他们长期观 察社会,深入体验人生,认真检索文献,总之,苦心孤诣才进行写作。
《长生殿》“盖经十 余年,三易稿而成”。
孔尚任说《桃花扇 》写“朝政得失,文人聚散 ,皆确考时地,全无假借”;又说,经过十余年的酝酿,“凡三易稿而书成”。
明清一些戏曲作品能成为经典,还在于作者掌握了戏曲创作的规律。
汤显祖曾“凡 文以意、趣、神、色为主。
”他认为作品所立之“意”,要有超越常人和前人的新意。
他通 过写杜丽娘这一典型人物与典型环境之间的冲突一经问世,便“家传户诵,几令《西厢》减价”。
“趣”是指戏曲作品故事情节生动,结构完整,能准确表现内容。
《牡丹亭》写杜丽娘 因情成梦,因梦而死,死而复生,曲折微妙地凸显封建时代青年对理想的追求。

秦砖汉瓦,并非专指“秦朝的砖,汉代的瓦”,而是泛指秦汉时期的青砖与古瓦。
它们历千年而不朽,以精美的文字、充满活力的生活场景,再现了当时人们的现实世界与美好愿景。
秦兵马俑的千军万马与气势万钧,见证了秦代制陶技术的高超。
用这种技术去制造宫殿上的陶瓦,不难想见它们的坚固与华美。
精美的陶瓦被广泛用于秦阿房宫的营建。
因为瓦当向外,所以或印图案,或刻文字,兼具建筑与装饰的作用。
它们承载着精美而丰富的图文,就像秦汉建筑上的“徽章”,宣告着早期宫殿“非壮丽无以重威”的营建法则。
现在出土的秦代瓦当上,图像多为鹿、豹、鱼、鸟等动物纹。
这种动物情结源自秦人祖先的游牧狩猎活动。
此后,汉承秦制,国力更加强盛,建长乐等四十余座宫殿,瓦当图案的艺术性也抵达前所未有的高度,尤其以青龙、白虎、朱雀、玄武四神兽瓦当最为出色。
四神兽瓦当的构图饱满得当,造型夸张,气势磅礴,雍容堂皇。
时至今日,但凡在当代设计中使用到四兽形象,都无法摆脱瓦当神兽造型的影响。
除了动物纹饰,云纹瓦当也广为使用。
云纹瓦当成为图案瓦当的主流与秦皇汉武等帝王渴望求仙升天、永享荣华的思想不无关系。
而瓦当纹饰发展到西汉时,又出现了文字瓦当。
“长生无极’’“长乐未央’’等文字瓦当就表达出了统治阶级的意志和人们的普遍愿望。

However, I was afraid that, especially when it comes to volunteeri ng in research, I wouldn’t be able to go into much depth with the research I would be doing. I needn’t have worried about this internship(实习期)though. It has been perfect for me because not only am I doing the same activities as all the other volunteers but I also get to do my own research in addition to those activities.The internship program I am following focuses on big predators(食肉动物). I have decided to focus on cheetahs(猎豹)for my individual project, collecting data on the two cheetahs that live in Rietspruit, one of the reserves that African Impact does research in. With both cheetahs having only been reintroduced into the area this year, there is still a lot of data that can be collected on the pair. Large predatorreintroduction is a common strategy used to return these animals to their historic range. The problem is that the success rates of these reintroductions are very low, mainly because of lack in research done on how different factors influence the reintroduction.Both cheetahs are wearing a GPS-collar from which I can download a lot of information including where the cheetah has been, what the weather was like and how far the cheetah travelled. Having organized and categorized the information, I have been able to create some very interesting graphs.Even though it is quite difficult since I’ve never done any research like this, I really enjoy all the challenges and problems I have had to face and solve. And I’m glad that I can do something to help wildlife.24. Why did the author take a gap year after high school?A. He was asked to do some voluntary work.B. He didn’t think he was quite ready yet.C. He wanted to do some travelling in Africa.D. He didn’t really like receiving higher education.25. What did the author realize after joining the internship program?A. It was what he had expected.B. It separated him from others.C. It was too challenging for him.D. It was really suitable for him.26. The author’s work mainly involves ___________.A. collecting information about two cheetahsB. observing two cheetahs in the wild secretlyC. walking around Rietspruit to serve scientistsD. collecting data on some different big predators27. What is the best title for the text?A. My experience on the predator research internshipB. My experience of rescuing wildlife in AfricaC. My experience of receiving higher educationD. My experience of protecting cheetahsCWhen you start working on something but don’t finish it, thoughts of the unfinished work continue to jump into your mind even whe n you’ve moved on to other things. Psychologists refer to this psychological phenomenon as the Zeigarnik effect. The effect was first observed by a Russian psychologist named Bluma Zeigarnik. While sitting in a busy restaurant in Vienna, she noted the waiters had better memories of unpaid orders. Once the bill was paid, however, the waiters had difficulty remembering the exact details of the orders.In one of her studies, participants were asked to complete simple tasks such as putting together puzzles, or solving math problems. Half of the participants were interrupted halfway through these tasks. After an hour-long delay, Zeigarnik asked the participants to give an account of what they’d been working on. She discovered that those who had their work interrupted were twice as likely to remember what they had been doing as those who had actually completed the tasks.We can use this effect to our advantage. For example, if you’re struggling to memorize something important, momentary interruptions might actually work to your advantage. Rather than simply remember the information over and over again, review it several times and then take a break. While you’re focusing on other things, you’ll find yourself mentally returning to the information you were studying.We often put off tasks until the last moment, only completing them in a rush at the last possible moment. Unfortunately, this tendency can lead to heavy stress and even poor performance. One way to overcome this is to put the Zeigarnik effect to work. Sta rt by taking the first step, no matter how small. Once you’ve begun,but not finished your work, you’ll find yourself thinking of the task until, at last, you finish it. You might not finish it all at once, but each small step you take puts you closer to your final goal.28. What does the Zeigarnik effect refer to ?A. Waiters tend to have good memories.B. Once interrupted, one will forget things easily.C. Most people can’t focus on one thing for a long time.D. People remember unfinished tasks better than completed ones.29. What were all the participants required to do in the study?A. Describe their tasks.B. Express their feelings.C. Test their intelligence.D. Design simple activities.30. How should we study according to the Zeigarnik effect?A. Repeat over and over again.B. Divide up our study session.C. Focus on several tasks at a time.D. Have enough rest before studying.31. What’s the main idea of the last paragraph?A. How to get rid of heavy stress.B. Why we should set a final goal.C. How to break the habit of delaying work.D. Why we always complete tasks in a rush.DWe’ve certainly seen a dog nursing a wound, or a deer calling out in pain. But many animals suffer in silence. The most silent sufferers in the animal world may be fish.Do fish feel pain? A new study from the University of Liverpool has found that fish feel pain in a way that’s “strikingly similar” to humans. For the study, Lynne Sneddon, from the university’s Institute of Integrat ive Biology, reviewed the existing body of research 98 studies in all and concluded that they feel pain just as sharply as we do.“When subject to a potentially painful event, fish show changes in behavior such as stopping feeding and reduced activity, which are prevented when a pain-relieving drug is provided. In fact, like us, they breathe heavily and stop eating when they’re hurting. They will even rub the part of their body that aches.” Sneddon notes in a university release.To understand pain in other species, scientists look at nociceptors, which send signals to the brain when the body is being damaged. Humans have them throughout their skin, bones and muscles. Nociceptors have also been found in many other species, including even those tiny fruit flies. Fish have the same means to detect pain signals and the equipment to receive them.Besides, the fishermen’s opinion that fish feel no pain just doesn’t add up from an evolutionary view. Pain is an efficient messenger that tells us that we’vegot a pro blem. An animal that can’t feel it won’t get that memo(备忘录), even if it hurts itself.“If we accept fish experience pain, then this has great significance for how we treat them,” Sneddon says. “Care should be taken when handling fish to avoid damaging the ir sensitive skin and they should be humanely caught and killed.”32. What can we learn about fish?A. They are insensitive to pain.B. They are able to sense pain.C. They won’t react to painkillers.D. Their brain is the first to send pain signals.33. What will a fish do when its lips get hurt?A. It might rub its lips.B. It will keep its mouth open.C. It will swim around like crazy.D. It will keep eating to forget pain.34. What is the significance of the study according to Sneddon?A. People will treat fish in a kinder way.B. People can understand evolution better.C. People can develop more drugs to save fish.D. People will think of more ways to catch fish.35. What does the underlined part “add up” probably mean?A. DisappearB. Put forwardC. Make senseD. Happen第二节,七选五(共5小题;每小题2分,满分10分)Walking with a purposeHumans were made for walking. With our strong leg muscles, our bodies were literally designed with walking in mind-which is what makes it such perfect exercise. 36 And best of all, it’s a great way to see new things and meet new people!This month, why not focus on walking with a purpose? Wherever you are, in the city or at the campground, you’ll find plenty of walking going on. Maybe you already love to walk, but you’re getting tired of going your same old route day after day. Or maybe you’re new to walking and aren’t sure how to get started.37 To get started, sit down with a map and make a plan. Ask yourself, what do you want to get out of walking aside from the health benefits? Do you want to meet other people? 38 Get out into the wilderness or explore a city? Knowing your priorities will help you decide on the type of walk you want to do.If making friends and socializing is your goal, call up your friends and schedule walks with them. 39 Go online and look up your local mall or shopping center. Many malls have groups that come every day, or every weekend, to “walk the mall”. These groups are always happy to include one more walker!40 Then tie on your walking shoes and prepare to get to know the place from the ground up! Many of our great historic cities offer detailed and well-planned walking tours. Nearly any city you can think of offers a walking tour with maps, provided by the tourist bureau. And small towns generally have a scenic route that will carry you past its best boutiques(精品店), shops, and cafes.A. See new places?B. Head to a new city.C.
