二、非选择题（共52分）

13. 根据材料并结合所学知识回答问题。

唐中期，杜佑感叹秦朝“以区区关中灭六强国”，而唐朝同样定都于关中，版图广阔，“竭万方之财，上奉京师”，国势却日益衰落。他分析说，“商鞅佐秦，以为地利不尽”，扩大每亩的面积，以此增加农夫耕种数量；招纳秦国以外的人前来耕种，“优其田宅，复及子孙”；“非农与战不得入官。大率百人以五十人为农，五十人习战，故兵强国富。”“其后仕宦途多，末业日滋。今大率百人才十人为农，余皆习他技。又秦汉郑渠（郑国渠）溉田四万顷，白渠溉田四千五百顷，永徽（唐高宗年号，650～655年）中，两渠灌浸不过万顷，大历（唐代宗年号，766～779年）初减至六千亩。亩朘（削减）一斛，岁少四五百万斛。地利耗，人力散，欲求强富，不可得也。”

——据《新唐书》（1）根据材料，概括指出唐代关中社会经济状况与秦相比有何变化。（10分）

（2）杜佑所批评的“大率百人才十人为农，余皆习他技”现象，实际上反映了社会经济的发展。简析这一现象产生的原因及其影响。（16分）

14. 结合相关史实说明“秦始皇完成统一大业是顺应历史潮流的伟大壮举”。

15 . 阅读下列材料：

材料一（太和）十有八年（公元494年）……革衣服之制。十有九年……六月己亥，诏不得以北俗之语于朝廷，若有违者免所居官。……丙辰，诏迁洛之民死葬河南，不得还北，于是

代人南迁者悉为河南洛阳人。…… 九月庚午，六官及文武尽迁洛阳。

——《魏书·高祖纪》下材料二?北齐初，（齐文宣帝）高洋曾问汉族士大夫杜弼：‘治国当用什么人？’，杜弼说：‘鲜卑人只会骑马坐车，治国当用汉人。’高洋听后，不久就把杜弼杀了。甚至他的太子高殷也因受汉文化的熏陶，被认为是得了‘汉家性质’，几乎被杀掉。北齐末，（齐后主）高纬又杀汉族官吏，被杀汉族官吏的家属发往北边，妇女罚作官奴婢……这样，北齐政权日益鲜卑化，鲜卑语也渐渐流行。?

（北周奠基人）宇文泰是外鲜卑人，重用汉人苏绰制定制度，苏绰对汉族统治者的治国经验加以总结，奏上‘六条诏书’。宇文泰下令官吏学习，并颁布全国实行。北周后期，周武帝解脱了鲜卑旧俗，真正接触汉文化优秀部分，最明显的表现是释放奴婢……基本解决了魏晋以来残存的奴隶制问题。?

北齐和北周，东西相对，以黄河为界。先时，河西的周人唯恐齐人乘河向西，整个冬季，守河将士天天去推冰，年年如此，后来周人不再推冰，轮到河东的齐国将士开始推冰，防备周人东渡。?

——引自郭伯南《新编中国史话》（1）依据材料一指出“高祖”采取的治国措施。请运用所学知识给予简要评析。

（2）北齐与北周的统治政策有何不同？结果如何？你从中得到了什么启示？

一、选择题

ACAAB DADAA CA

二、非选择题

13. （1）水利工程衰败；农业收获量减少；越来越多的人从事工商业等活动，农业劳动力剧减。（2）原因：农业技术改进，农业生产水平提高，以人力投入保证农业收入的状况得以改变。影响：工商业获得发展的基础，从事工商业的人口增加，商业活动趋于繁荣。

14. 参考答案：（1）战国以来铁农具、牛耕技术的进一步推广，使井田制进一步瓦解，封建土地私有制出现，新兴地主阶级力量壮大。（2）为了避免兼并战争中的失败，各诸侯国纷纷进行改革，确立了封建制度。（3）兼并战争不仅使诸侯国的数目减少，而且促进了民族融合的发展。（4）战争给人民带来了灾难，人民渴望统一。（5）秦国商鞅变法最为彻底，为秦统一奠定了坚实的基础。（6）嬴政即位后，制定了统一国家的战略，并网罗人才，最终于公元前221年灭六国，统一中国。（7）秦的统一，结束了春秋战国以来长期分裂的局面，有利于中央集权的加强，有利于社会的安定，经济的发展，有利于多民族国家的发展。综上所述，秦始皇完成统一大业是顺应历史潮流的伟大壮举。

15. （1）措施：实行汉化政策（或改革鲜卑旧俗，穿汉服，说汉话）；迁都洛阳。评析：孝文帝这些举措，主观上是为了缓和当时的阶级矛盾和民族矛盾，巩固统治；但客观上有利于鲜卑族接受汉族先进文化，消除民族之间的隔阂，促进了民族融合。

（2）不同：北齐屠杀汉人实行鲜卑化，北周重用汉人采用汉族先进制度；北齐将汉人为奴，北周释放奴婢。影响：北齐由强转弱，北周由弱转强，最终北周灭北齐统一北方。启示：落后的民族最终为先进的民族文化所征服。

I’m walking on a path in the forest in the Central African Republic. Unexpectedly, I’m face-to-face with the gorilla, who begins screaming at 2 top of her lungs. That makes her baby scream, and then a 400-pound male appears. He screams the 3 (loud) of all. The noise shakes the trees as the male beats his chest and charges toward me. I quickly lower myself, ducking my head to avoid 4 (look) directly into his eyes so he doesn’t feel 5 (challenge). My name is Mireya Mayor. I’m a 6 (science) who studies animals such as apes and monkeys. I was searching 7 these three western lowland gorillas I’d been observing. No one had seen them for hours, and my colleagues and I were worried. When the gorillas and I frightened each other, I was just glad to find 8 (they) alive. True to a gorilla’s unaggressive nature, the huge animal 9 (mean) me no real harm. He was just saying: “I’m king of this forest, and here is your reminder!” Once his message was delivered, he allowed me 10 (stay) and watch. 1.____________ 2.____________ 3.____________ 4.____________ 5.____________ 6.____________ 7.____________ 8.____________ 9.____________ 10.____________ 二．（共10小题；每小题1.5分，满分15分）(2018年6月浙江卷) Few people I know seem to have much desire or time to cook. Making Chinese 1 (dish) is seen as especially troublesome. Many westerners 2 come to China cook much less than in their own countries once they realize how cheap 3 can be to eat out. I still remember 4 (visit) a friend who’d lived here for five years and I 5 (shock) when I learnt she hadn’t cooked once in all that time. While regularly eating out seems to 6 (become) common for many young people in recent years, it’s not without a cost. The obvious one is money; eating out once or twice a week may be 7 (afford) but doing this most days adds up. There could be an even 8 (high) cost on your health. Researchers have found that there is a direct link between the increase in food eaten outside the home and the rise in 9 (weigh) problems. If you are not going to suffer this problem, then I suggest that the next time you go to your mum’s home 10 dinner, get a few cooking tips from her. Cooking food can be fun.

His mother had kept on hinting that there would be a big surprise for him during the vacation. Kevin took out his scrapbook (剪贴簿). The exams had just finished, and summer vacation had just started. Now he was free as a bird — free to draw, paint, play basketball, and watch television…anything he wanted to do. Suddenly, the doorbell rang, startling (使惊吓) him. It was his pain of a cousin, Max. “Hi!” screamed Max as he jumped on Kevin’s bed. “I have come to stay here for the holidays.” Kevin had never expected his mother’s surprise to be this bad. If this was the start of his vacation, then the next few weeks were going to be the worst experience of his life. The next few days were horrible for Kevin. After breakfast, Kevin decided to make a painting. Luckily, Max was not around. Kevin spread out all his art supplies and started painting some beautiful scenery. When he was doing the finishing touches, Max entered the room with a Pepsi bottle. He slipped on some water, spilling Pepsi all over the painting and totally ruining it. The next day was even worse. Everything was peaceful until the evening. It all started when Max put the dirty clothes in the washing machine. After some time, Kevin heard some strange sounds from the washing machine. He went to check and found that Max had put his best pair of shoes into the machine, along with the clothes. One day, Kevin was looking through the newspaper when some interesting news caught his attention. He read it aloud: “The world famous philatelist (集邮家) Dick Brown’s stamps were stolen last week from his house. Several other stamp robberies also have taken place, and police suspect that all the robberies are linked.” This piece of news concluded by warning all stamp collectors to keep their stamps safe.

浙江省杭州市萧山区第三高级中学高三英语限时训练1月日 含答案

A Famous centenarians (百岁老人) still active in arts, science are in no mood to retire. "Those who stand still, die," is one of Oliveira's favorite phrases. He knows from experience what it means, as the Portuguese film director has reached the age of 102 and is still active in his profession. Every year, Oliveira shoots a film and is currently working on his next project. "You have to work, work, work in order to forget that death is not far away," he said. When asked about his age, Oliveira said with some humility: "It's down to mother nature. It gave to me what it took from others." Being both mentally and physically fit in old age is partly a matter of luck, but it also has something to do with character. Not every white-haired person is wise and social skills, openness and the ability to train the brain are essential for senior citizens. Along with the architect Oscar Niemeyer (103), Nobel laureate Montalcini (101) and director Kurt Maetzig (100), Oliveira is one of those people of whom it would be very wrong to think as members of a listless elderly generation. Another master in his profession is the architect Oscar Niemeyer. The 103-year-old Brazilian is best known for his futuristic-looking（未来派的）buildings in Brasilia, but he also speaks out on behalf of the poor. "The role of the architect is to struggle for a better world where we can develop a form of architecture that serves everyone and not just a privileged few," said Niemeyer recently. He spends almost every day working in his office in Copacabana, and even when he falls ill he keeps working on ideas: After a gallbladder (胆囊) operation he composed a samba tune (桑巴舞曲) in the clinic. Another man who could sing a song about age is 107-year-old Heesters. The Dutch-born opera singer spent most of his life performing in Germany, where he still works. Recently Heesters said: "I want to be at least 108-years-old." He also plans to keep performing. "Should I just sit at home and wait until they come and pick me up?" Heesters has not given up trying to add to his tally of awards and is looking for a "good stage role". Italian scientist Rita Levi-Montalcini, who is 101-year-old and is still active in medical science, has described the force that keeps driving her on: "Progress is created through imperfection." In 1986 she and her lab colleague were awarded the Nobel Prize for Medicine for their work on nerve growth factor. She's convinced that humans grow on challenges.
