关于国家的这种理解,反映了我国古代A. 非常重视祭祀B. 以农业为立国之本C. 农业与土地的关系D. 小农经济的特点【答案】B【解析】试题分析:据材料提到,“社稷”是国家的代称。
其中,“社”指土地之神,“稷”指主管五谷之神,结合所学知识可知,这反映了我国古代以农业为立国之本,故B正确。
土地和五谷不能说明非常重视祭祀,故A排除。
材料主旨不在于农业与土地的关系,故C排除。
小农经济的突出特点是自给自足、精耕细作,材料未涉及,故D排除。
考点:古代中国经济的基本结构与特点·发达的古代农业·特点2. “大街小巷叫卖食品杂务的小贩‘吟叫百端’,大小商店铺席连绵不断,夜市直至三更尽,五更又开晓市。
”上述历史现象最早出现于A. 西汉长安B. 唐朝洛阳C. 北宋开封D. 南宋临安【答案】C【解析】依据题干中“大街小巷叫卖食品杂物的小贩吟叫百端……夜市直至三更尽,五更又开晓市。
”的信息说明夜市和早市的出现,市场打破时空界限,根据所学知识可知,诗句中的现象最早出现在北宋的都城开封,故C项正确;汉唐时期城市主要是政治和军事中心,经济功能比较弱,故AB项排除;D项晚于C 项,排除。
3. 鸦片战争前夕,清政府实行的闭关锁国政策的含义是A. 严格限制对外交往B. 禁绝中国对外贸易C. 一概排斥西方事物D. 封闭边界、固守疆域【答案】A【解析】根据所学知识可知,清政府实行的闭关锁国政策不是和外界没有交往,而是严禁限制对外交往,在鸦片战争前夕,清政府只允许广州一处对外通商,故A项正确,BCD项错误。

ABefore traveling around the world, take some time and find out what sightseeing destinations are. Some of those spots that most guides mention are the following thrilling attractions.Victoria FallsVictoria Falls has always been considered to be an incredible place worth taking pictures of. There are a lot of spots that tourists love. Some of them are very dangerous for people. Yet the brave are ready to overcome their fear for a shot of lifetime.Arctic Cliff FaceCliff does not make the most comfortable place for camping. Being camped on the ground is far safer anyway. Despite all the inconvenience, the new trend is rapidlygaining popularity among climbing enthusiasts and outdoor addicts.Auckland’s Sky TowerAuckland’s Sky Tower is popular with bungee jumpers. Some celebrities, such as Beyonce, have already tried it, which proves that the place is not only safe but popular as well. The tower is 630 feet Call. At the top of the structure there is an observation deck. Trust us, most of those reading this article would prefer to stay on the ground rather than climb up this scary structure.North Yung as RoadThe Road of Death is the right name given to a road in Bolivia. Hundreds of peopledie here every year. The major cause of all those accidents is the road. The problem is that it is too narrow and badly maintained while here the traffic is heavier than anywhere else. Nevertheless, it seems like tourists will continue visiting this strange road despite its scary nickname.1. What is Victoria Falls famous for?A. Its narrow and badly maintained roadB.Its thrillingcampingC. Its dangerous but attractive spots for taking picturesD. Its scary structure2. North Yung as Road is called “the Road of Death” because.A. there is no necessary protection equipmentB. each year many people lose their lives thereC. it is built on the edge of the rockD. the traffic is the heaviest3. If you like bungee, you can go to .A. Victoria FallsB. Arctic Cliff FaceC. Auckland’ Sky TowerD.North Yung as Road4. What do the four places have in common?A. They are popular with climbers.B. They are a bit life-threatening.C. They all have beautiful scenery.D. They have been visited bycelebrities.BWhen I woke up, I made myself breakfast, sat and listened to the traffic. Some of my friends ask me how I can stand living somewhere so noisy. It’s true that there’s always some kind of noise in my neighborhood, but to me, these are the sounds of life.It was Saturday morning, so I decided to go to the park. The taxi is the fastest way to go but I took the bus instead.When you ride the bus, you get to see so much more of the city. It can be kind of loud on the bus, with some people talking on their phones, others chatting with their friends, and others playing music. It’s just like the traffic’s sounds, thou gh the noise on the bus represents people working, relaxing and living.Once I got to the park, I picked a bench over near the play area where kids play while their parents sit nearby. I can see and hear almost everything from there. People-watching is one of my favorite things to do. However, I like listening even better.

I don't think so. "Health is the greatest wealth." wise people say. You can't be good at your studies or work well when you are ill.If you have a headache, toothache, backache, earache or bad pain in the stomach, if you complain of a bad cough, if you run a high temperature and have a bad cold, or if you suffer from high or low blood pressure, I think you should go to the doctor’s. The doctor will examine your throat, feel your pulse, test your blood pressure, takeyour temperature, sound your heart and lungs, test your eyes, check your teeth or have your chest X-rayed. After that he will advise some treatment, or some medicine. The only thing you have to do is to follow his advice.Speaking about doctor's advice, I can't help telling you a funny story. An old gentleman came to see the doctor. The man was very ill. He told the doctor about his weakness, memory loss and serious problems with his heart and lungs. The doctor examined him and said there was no medicine for his disease. He told his patient to go to a quiet place for a month and have a good rest. He also advised him to eat a lot of meat, drink two glasses of red wine every day and take long walks. In other words, the doctor advised him to follow the rule:"Eat with pleasure, drink with pleasure and enjoy life as it is." The doctor also said that if the man wanted to be well again, he shouldn't smoke more than one cigarette a day. A month later the gentleman came into the doctor's office. He looked cheerful and happy. He thanked the doctor and said that he had never felt a healthier man. "But you know, doctor," he said, "it's not easy to begin smoking at my age."9.

ABefore traveling around the world, take some time and find out what sightseeing destinations are. Some of those spots that most guides mention are the following thrilling attractions.Victoria FallsVictoria Falls has always been considered to be an incredible place worth taking pictures of. There are a lot of spots that tourists love. Some of them are very dangerous for people. Yet the brave are ready to overcome their fear for a shot of lifetime.Arctic Cliff FaceCliff does not make the most comfortable place for camping. Being camped on the ground is far safer anyway. Despite all the inconvenience, the new trend is rapidly gaining popularity among climbing enthusiasts and outdoor addicts.Auckland’s Sky TowerAuckland’s Sky Tower is popular with bungee jumpers. Some celebrities, such as Beyonce, have already tried it, which proves that the place is not only safe but popular as well. The tower is 630 feet Call. At the top of the structure there is an observation deck. Trust us, most of those reading this article would prefer to stay on the ground rather than climb up this scary structure.North Yung as RoadThe Road of Death is the right name given to a road in Bolivia. Hundreds of people die here every year. The major cause of all those accidents is the road. The problem is that it is too narrow and badly maintained while here the traffic is heavier than anywhere else. Nevertheless, it seems like tourists will continue visiting this strange road despite its scary nickname.1. What is Victoria Falls famous for?A. Its narrow and badly maintained roadB.Its thrillingcampingC. Its dangerous but attractive spots for taking picturesD. Its scary structure2. North Yung as Road is called “the Road of Death” because.A. there is no necessary protection equipmentB. each year many people lose their lives thereC. it is built on the edge of the rockD. the traffic is the heaviest3.

They are a bit life-threatening.C. They all have beautiful scenery.D. They have been visited bycelebrities.BWhen I woke up, I made myself breakfast, sat and listened to the traffic. Some of my friends ask me how I can stand li ving somewhere so noisy. It’s true that there’s always some kind of noise in my neighborhood, but to me, these are the sounds of life.It was Saturday morning, so I decided to go to the park. The taxi is the fastest way to go but I took the bus instead.When you ride the bus, you get to see so much more of the city. It can be kind of loud on the bus, with some people talking on their phones, others chatting with their friends, and others playing music. It’s just like the traffic’s sounds, thoughthe noise on the bus represents people working, relaxing and living.Once I got to the park, I picked a bench over near the play area where kids play while their parents sit nearby. I can see and hear almost everything from there. People-watching is one of my favorite things to do. However, I like listening even better. The only problem is that there’s so much to see and hear in the park!Usually, I like to close my eyes. That way, I can pay more attention to the sounds and not get distracted by what I see. With my eyes closed, I could pick out parts of two old men’s conversation. One of them was telling the other about something his grandson said. I couldn’t hear the rest, but it must have been hilarious because his friend’s laugh was so loud.When I’m old, I hope tha t I too will have a friend who will sit in the park with me, and who will enjoy listening to the sounds of the city as much as I do.5.

读书其实是一种“遇见”。
打开书本的刹那,就开启了一扇去往不同时空的大门,碰见各种各样的人,听说形形色色的事,接触不同年代留下来的思想菁华。
如果说,“遇见”是读书与生俱来的产物,那么,选择怎样的“遇见”,读书人理应有属于自己的主动权。
苏东坡说得好:“书富如入海,百货皆有。
人之精力,不能兼收尽取,但得其所欲求者尔。
”那么,什么才是“所欲求者”?我想,除了要选择那些契合自己的兴趣爱好和功课长进的书籍外,关键一定要按优中选优、精中选精的原则,去选读那些经受过时间和一代又一代读者淘洗的经典。
须知,读一本经典抵得上读几十本、上百本普通之书。
而对于那些平庸的书籍,我们还是少读或者不读为妙。
那样的“遇见”,只是重复,只会无端损耗你去选择读一本经典的时间和精力,因此太不值得。
交朋友要交五湖四海的朋友,读书当然也是“遇见”的人和事越多越好,读书面越广越好。
读报看到一个材料:在当年的西南联大,许多教授在读书方面都是学贯中西,打通文理。
因此,吴宓、陈岱孙、金岳霖、贺麟等能用中国话语、中国文化娴熟诠释西学;冯至讲《浮士德》时,可以用“天行健:君子以自强不息”来诠释《浮士德》“一个越来越高尚越纯洁的努力,直到死亡”的主题。
一些从事自然科学研究的教授,也有深厚的传统文化学识。
物理学教授王竹溪编写《新部首大字典》,在语言学界颇有影响;化学系教授黄子卿工于书法,热爱旧体诗,时常与文学教授游国恩探讨诗歌;年轻的数学家华罗庚则对散曲充满热爱……读书的“遇见”,又并非不动脑筋地匆匆而过,而是一种主观能动的行为。
换言之,一定要避免人云亦云的做法,要“运用脑髓,放出眼光”,善于从无疑处读出有疑。

You can't be good at your studies or work well when you are ill.If you have a headache, toothache, backache, earache or bad pain in the stomach, if you complain of a bad cough, if you run a high temperature and have a bad cold, or if you suffer from high or low blood pressure, I think you should go to the doctor’s.The doctor will examine your throat, feel your pulse, test your blood pressure, take your temperature, sound your heart and lungs, test your eyes, check your teeth or have your chest X-rayed. After that he will advise some treatment, or some medicine. The only thing you have to do is to follow his advice.Speaking about doctor's advice, I can't help telling you a funny story. An old gentleman came to see the doctor. The man was very ill. He told the doctor about his weakness, memory loss and serious problems with his heart and lungs. The doctor examined him and said there was no medicine for his disease. He told his patient to go to a quiet place for a month and have a good rest. He also advised him to eat a lot of meat, drink two glasses of red wine every day and take long walks. In other words, the doctor advised him to follow the rule:"Eat with pleasure, drink with pleasure and enjoy life as it is." The doctor also said that if the man wanted to be well again, he shouldn't smoke more than one cigarette a day. A month later the gentleman came into the doctor's office. He looked cheerful and happy. He thanked the doctor and said that he had never felt a healthier man. "But you know, doctor," he said, "it's not easy to begin smoking at my age."9. The writer thinks that _____.A. work is as important as studiesB. health is more importantthan wealthC. medicine is more important than pleasureD. nothing is more important thanmoney10. The doctor usually tells his patient what to do _____.A. without examining the patientB. after he has examined the patientC. if the patient doesn't take medicineD. unless the patient feels pain11. The underlined part means "_____".A. he will be well againB. he wasn't a healthy manC. he was feeling worse than beforeD. he was feeling better than ever12. From the last sentence of the passage, we learn the man _____ before the doctor told him not to smoke more than one cigarette a day.A. was a heavy smokerB. didn't smoke so muchC. didn't smokeD. began to learn to smokeDMany Chinese students who have learnt English for more than ten years are still unable to speak English very well when they meet a foreigner. They seem to have mastered the basic language structure(结构), but a conversation in English will make them feel uneasy. They are afraid that other people might find out their mistakes.It's uncommon that many students who are bad speakers of English can write English perfectly. This proves that they are unable to organize their idea in English. The center of the problem is that they lack practice and confidence (自信).Why should you be afraid? Do you fear those foreigners with whom you are speaking? Don't be shy, they will not laugh at you just for a little mistake you make. The best way to get rid of trouble is to learn to speak by speaking more. I am sure that constant (持续的)practice will help you succeed.13. What's the best topic for the passage?A. How to Speak to ForeignersB. How to Study English WellC. How to Organize the Idea in EnglishD. Practise Speaking English All the Time14. Many Chinese students can write English very well, but they cannot speak English fluently because ________A. they seldom meet foreignersB. they seldom practise speaking EnglishC. they had no chance to speak EnglishD. they think it's enough to master the basic language structure only15. So many Chinese students are afraid speak to foreigners becauseA. they are afraid they can't understand foreignersB. they don't think their English is poorC. they worry about making mistakes in their speakingD. they didn't tike speaking to foreigners第二节(共5小题;每小题2分,满分10 分)(7选5题)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。
