第Ⅰ卷(共60分)一.选择题(本大题共20小题,每小题3分,合计60分。
每小题只有一个正确答案)1.某学者指出:“中国史上秦以前的所谓封建,乃属一种政治制度,与秦以后的郡县制度相针对。
在西洋历史中古时期有一段所谓Feudalism的时期,Feudalism则并不是一种制度,而是他们的一种社会形态。
现在把中国史上封建二字来翻译西洋史上之Feudalism,便犯了名词纠缠之病。
”对其观点理解正确的是A.中国史秦朝以前的封建是指封邦建国B.西洋历史中的封建是指一种思想潮流C.中国秦以后的社会是真正的封建社会D.中国史与西洋史没必要进行比较研究2.许倬云《西周史》记载:“西周分封并不只是周人殖民队伍分别占有一片东方的故地,分封制度是人口的再编组(注:是族群间关系的重新组合),每一个封君受封的不仅是土地,更重要的分领了不同的人群。
”对此理解不正确的是A.西周分封伴随着殖民和扩张B.授民授土是西周分封的基本内容C.西周分封制推动了族群交融D.西周分封制的运作单纯依恃武力3.在一般公共场合常出现“同胞们”、“父老兄弟们”、“天下一家”、“四海之内皆兄弟”等用语,又如常常借用亲属称谓词来称没有血缘关系的人为“叔叔”、“伯伯”、“阿姨”等等。
这些所反映现象的是A.血缘团体内部的凝聚力强固B.血缘意识影响人们的行为模式C.宗法血缘组织是生命共同体D.血缘组织与政治组织间的互动4.周代宗法制情形可从古代经典中约略窥见,如《仪礼·丧服·传》:“大宗者尊之统也,大宗者收族(按,指团结族人)者也,不可以绝”,“异居而同财,有馀则归之宗,不足则资之宗”;又如《礼记·曲礼》:“支子不祭,祭必告于宗子”。
材料主要表明周代早期A.血缘凝聚力受到地缘成分的影响而崩解B.宗法制的特色是父系与嫡长子继承制C.政治、经济与社会生活受宗法力量支配D.丧服制度和行为规范弱化了血缘认同5.周天子掌有统治天下的权力,分封诸侯;诸侯掌有统治封国的权力,又分封卿大夫;卿大夫掌有统治封邑的权力,又分封士。

Aiming to understand each other better and build up our bodies, our class had a spring outing last Saturday.As scheduled, we gathered together at 8: 30 am at the gate of our school. We went to our destination by bus, laughing and singing all the way. Much to our delight, the trip involved mountain climbing as well as a picnic. Hardly had we reached the top of the mountain when we enjoyed an awesome view of the whole city.Exhausted as we were on the way back to school, we all regarded this outing as an unforgettable experience, for it not only made us get close to nature with fresh air and fantastic scenery, but also enhance the friendship between us students and promote our mutual cooperation.读后续写:Now they were twenty miles from Brunswick. And the young people took over window seats on the right side, waiting for the approach of the great oak tree. Vingo stopped looking, tightening his face into the ex-con’s mask, as if fortifying himself against still another disappointment. Then it was ten miles, and then five. The bus acquired a dark hushed mood, full of silence, of absence, of lost years, of the woman’s plain face, of the sudden letter on the breakfast table, of the wonder of children, of the iron bars of solitude.Then suddenly all of the young people were up out of their seats. They were screaming and shouting and crying, doing small dances, shaking clenched fists in triumph and exaltation. All except Vingo. Vingo sat there stunned, looking at the oak tree. It was covered with yellow handkerchiefs twenty of them, thirty of them, maybe hundreds, a tree that stood like a banner of welcome blowing and billowing in the wind, turned into a gorgeous yellow blur by the passing bus. As the young people shouted, the old con slowly rose from his seat, holding himself tightly, and made his way to the front of the bus to go home.听力原文:1. W: Hi, John, Would you like to go to a badminton game after school tomorrow?M: I’d love to, Sandy, but I’ve already arranged to go to the cinema with Grace.2. M: I don’t think I should wear a dark shirt for a wedding. It just isn’t appropriate.W: Well, the only clean shirts you have are the white one, the black one and the dark blue one.M: So, there is only one choice.3. M: Sorry, Miss Green. I failed your subject again but I really tried my best. W: No one is sure to succeed every time. Cheer up, young man. You will have more chances.M: Thank you, Miss Green. I’ll try harder next time.4. W: I don’t know how you can eat so much yet never put on any weight, son. Your father’s got the same luck. I can’t take a bite w ithout calculating how many calories I am taking.M: But remember Aunt Louise, Mom? She ate a lot and never gained a pound.5. M: Don’t you like the coat you just tried on?W: Well, I like the color and fabric.M: And it is really nice and reasonably priced.W: Yes. I would have bought it right away if they had had it in my size.6. M: Good morning. How can I help you?W: Hello, I need to get this dress cleaned. I spilled pasta sauce on it last night. It’ s silk, so I can’t wash it at home. Is it ruined?M: Oh, no, I can get that out for you. It will be ready tomorrow morning.W: I’m going to a work event tonight and I need to wear it. Can you have it ready by this afternoon?M: Sure, I can do that for you. Why not come back around 4: 00 pm?W: That’s p erfect. Thank you so much.7. W: Excuse me. I’d like to have the package and the letter posted.M: Would you like to mail by air or by sea?W: How long will it take to mail things to the US by air?M: About 10 days. You can send it by express mail if you need it faster. It will only take three or four days.W: Then, express mail for the package. It’s urgent. The faster, the better. And the letter by registered mail.M: OK. The package is 3 kilograms. That’ll be £ 20 for postage.W: Yes. And the letter?M: Registered. That is £ 3. So give me £ 23.W: Here you go.8. M: Hi, Gina! How was your trip to the States?W: Very busy. Having a lot of meetings, I didn’t have much time to see New York.M: What a pity! Actually, I’ll have a trip there too next week.W: Do you? Then take my advice, do watch the “Health in the Air” program on the plane. It really works.M: Oh, really?W: Yes, I followed the directions in the program, and when I arrived in New York, I felt good and no jet lag at all.M: Em, So, what did you do?W: Well, I didn’t drink any alcohol or coffee, but a lot of water and I did some of the exercises in the program.M: How many passengers did the exercises?W: Not many.M: And how much alcohol did they drink?W: A lot! It was more popular than mineral water.M: So, basically, it’s a choice. Mineral water and exercises, or alcohol and jet lag.W: That’s right!9. W: There’s a place in Venezuela where lightning strikes about 200 days a year.M: Are you serious?W: Yep. Locals call it “the Never-Ending Storm of Catatumbo” because the area is near the Catatumbo River. Scientists found that most of the lightning strikes between April and November. NASA named the area “the Lightning Capital of the World”.M: Why does the area get so many storms?W: The Andes Mountains are on one side of the river, and the Cabben Sea is on the other side. Cool mountain winds move into the valley and hit warm sea air, creating the perfect conditions for lightning.M: Are the people there afraid of getting hit?W: Most people stay inside at night, but they don’t really worry about it. The chances of being struck by lightning are pretty slim. In the US, about one in every 12, 000 people get hit in their lifetime.M: Yeah, but we’re tal king about an area that gets struck by lightning about 50% of the time.W: True. This article says that near the Catatumbo River, one in three people get struck every year.M: Wow. That’s really scary! I would never go outside if I lived there.10. Hello, everyone. My name is Alicia, and I live in the state of Guanajuato in central Mexico. Today, I’d like to tell something about my hometown and people here. Here in Guanajuato, music and dancing are a big part of life. There are a lot of festivals here, and many kinds of music. Many young people like rock or pop music but my favorite is traditional Mexican music, which is the kind of music my grandparents and great grandparents listened to. I don’t know why but I’m just crazy about it. I’m a folk dance r, and I love to perform atspecial events, which gives me chances to enjoy myself. To be a folk dancer, you have to love the culture and the music here. That’s the most important thing, but we also need to work hard and practice a lot. We dance in groups, and every person has to know the steps. And we can’t buy traditional folk dance dresses at the store, so we have to make our own. We wear traditional dresses that only come from this part of Mexico.阅读理解详解:A【导语】这是一篇应用文。
