材料一:历史地理学的起源至少可以追溯到我国最早的地理学著作《禹贡》。

这篇托名大禹的著作实际产生在战国后期。

《禹贡》虽以记载传说中的大禹治水后的地理状况为主,但也包含了对以往地理现象的追潮,含有历史地理学的成分。

成书于公元1世纪的《汉书·地理志》对见于典籍记载的重要地理要素,包括古国、历史政区、她名、河流、山岭、古迹等都做了记载和简要考证,并不局限于西汉一朝。

作者班固比较充分地利用己有的地理记载和地理研究成果,使得中国历史地理学研究初具雏形。

同样,成书于公元6世纪的《水经注》也从传世的数百种地理著作中搜集整理了大量史料,并做了深入的考证和研究。

今天,我们之所以还能知道先秦的某一个地名在现在的什么地方,能知道秦汉以降的疆域范围,能够大致了解黄河早期的几次改道,都离不开这两种著作。

在中国漫长的历史中,皇朝的更迭、政权的兴衰、疆域的盈缩、政区的分合和地名的更改不断发生;黄河下游及其支流的频繁决溢改道又经常引起有关地区地貌及水系的变迁,给社会生活带来相当大的影响。

中国古代繁荣的文化使这些变化大多得到了及时而详尽的记载,但由于在如此巨大的空间和时间中所发生的变化是如此复杂,已不是一般学者所能随意涉足,因而产生了一门专门学问——沿革地理。

沿革地理研究的内容关系有国计民生,也是治学的基础,例如历史她名的注释和考证、历代疆域和政区的变迁、黄河等水道的变迁,特别是与儒家经典和传统正史的理解有关的地理名称和地理知识,都被看成是治学的基本功。

Mailing your entry on October 30.BJennifer Mauer has needed more willpower than the typical college student to pursue her goal of earning a nursing degree. That willpower bore fruit when Jennifer graduated from University of Wisconsin-Eau Claire and became the first in her large family to earn a bachelor's degree.Mauer, of Edgar, Wisconsin, grew up on a farm in a family of 10 children. Her dad worked at a job away from the farm, and her mother ran the farm with the kids. After high school, Jennifer attended a local technical college, working to pay her tuition (学费), because there was no extra money set aside for a college education. After graduation, she worked to help her sisters and brothers pay for their schooling.Jennifer now is married and has three children of her own. She decided to go back to college to advance her career and to be able to better support her family while doing something she loves: nursing. She chose the UW-Eau Claire program at Ministry Saint Joseph's Hospital in Marshfield because she was able to pursue her four-year degree close to home. She could drive to class and be home in the evening to help with her kids. Jennifer received great support from her family as she worked to earn her degree: Her husband worked two jobs to cover the bills, and her 68-year-old mother helped take care of the children at times.Through it all, she remained in good academic standing and graduated with honors. Jennifer sacrificed (牺牲) to achieve her goal, giving up many nights with her kids and missing important events to study. "Some nights my heart was breaking to have to pick between my kids and studying for exams or papers." she says. However, her children have learned an important lesson witnessing their mother earn her degree. Jennifer is a first-generation graduate and an inspiration to her family - and that's pretty powerful.4.What did Jennifer do after high school?A. She helped her dad with his work.B. She ran the family farm on her own.C. She supported herself through college.D. She taught her sisters and brothers at home.5.Why did Jennifer choose the program at Ministry Saint Joseph's Hospital in Marshfield?A. To take care of her kids easily.B. To learn from the best nurses.C. To save money for her parents.D. To find a well-paid job there.6.What did Jennifer sacrifice to achieve her goal?A. Her health.B. Her time with family.C. Her reputation.D. Her chance of promotion.7.What can we learn from Jennifer's story?A. Time is money.B. Love breaks down barriers.C. Hard work pays off.D. Education is the key to success.CIn the mid-1990s, Tom Bissell taught English as a volunteer in Uzbekistan. He left after seven months, physically broken and having lost his mind. A few years later, still attracted to the country, he returned to Uzbekistan to write an article about the disappearance of the Aral Sea.His visit, however, ended up involving a lot more than that. Hence this book, Chasing the Sea: Lost Among the Ghosts of Empire in Central Asia, which talks about a road trip from Tashkent to Karakalpakstan, where millions of lives have been destroyed by the slow drying up of the sea. It is the story of an American travelling to a strange land, and of the people he meets on his way: Rustam, his translator, a lovely 24-year-old who picked up his colorful English in California, Oleg and Natasha, his hosts in Tashkent, and a string of foreign aid workers.This is a quick look at life in Uzbekistan, made of friendliness and warmth, but also its darker side of society. In Samarkand, Mr. Bissell admires the architectural wonders, while on his way to Bukhara he gets a taste of police methods when suspected of drug dealing. In Ferghana, he attends a mountain funeral (葬礼) followed by a strange drinking party. And in Karakalpakstan, he is saddened by the dust storms, diseases and fishing boats stuck miles from the sea.Mr.Bissell skillfully organizes historical insights and cultural references, making his tale a well-rounded picture of Uzbekistan, seen from Western eyes. His judgment and references are decidedly American, as well as his delicate stomach. As the author explains, this is neither a travel nor a history book, or even a piece of reportage. Whatever it is, the result is a fine and vivid description of the purest of Central Asian traditions.8.What made Mr Bissell return to Uzbekistan?A. His friends' invitation.B. His interest in the country.C.His love for teaching.D. His desire to regain health.9.What does the underlined word "that" in paragraph 2 refer to?A. Developing a serious mental disease.B. Taking a guided tour in Central Asia.C. Working as a volunteer in Uzbekistan.D. Writing an article about the Aral Sea.10.Which of the following best describes Mr Bissell's road trip in Uzbekistan?A. Romantic.B. Eventful.C. Pleasant.D. Dangerous.11.What is the purpose of this text?A. To introduce a book.B. To explain a cultural phenomenon.C. To remember a writer.D. To recommend a travel destination.DAccording to a recent study in the Journal of Consumer Research, both the size and consumption habits of our eating companions can influence our food intake. And contrary to existing research that says you should avoid eating with heavier people who order large portions (份), it's the beanpoles with big appetites you really need to avoid.To test the effect of social influence on eating habits, the researchers conducted two experiments. In the first, 95 undergraduate women were individually invited into a lab to ostensibly (表面上)participate in a study about movie viewership. Before the film began, each woman was asked to help herself to a snack.An actor hired by the researchers grabbed her food first. In her natural state, the actor weighed 105 pounds. But in half the cases she wore a specially designed fat suit which increased her weight to 180 pounds.Both the fat and thin versions of the actor took a large amount of food. The participants followed suit, taking more food than they normally would have. However, they took significantly more when the actor was thin.For the second test, in one case the thin actor took two pieces of candy from the snack bowls. In the other case, she took 30 pieces. The results were similar to the first test: the participants followed suit but took significantly more candy when the thin actor took 30 pieces.The tests show that the social environment is extremely influential when we're making decisions. If this fellow participant is going to eat more, so will I. Call it the "I'll have what she's having'' effect. However, we'll adjust the influence. If an overweight person is having a large portion, I'll hold back a bit because I see the results of his eating habits. But if a thin person eats a lot, I'll follow suit. If he can eat much and keep slim, why can't I?12.What is the recent study mainly about?A. Food safety.B. Movie viewership.C. Consumer demand.D. Eating behavior.13.What does the underlined word ''beanpoles" in paragraph 1 refer to?A. Big eaters.B. Overweight persons.C. Picky eaters.D. Tall thin persons.14.Why did the researchers hire the actor?A. To see how she would affect the participants.B. To test if the participants could recognize her.C. To find out what she would do in the two tests.D. To study why she could keep her weight down.15.On what basis do we "adjust the influence" according to the last paragraph?A. How hungry we are.B. How slim we want to be.C. How we perceive others.D. How we feel about the food.第二节(共5小题;每小题2.5分,满分12.5分)阅读下面短文,从短文后的选项中选出能填入空白处的最佳选项。

一、现代文阅读(35分)(一)现代文阅读Ⅰ(本题共5小题,19分)阅读下面的文字,完成1~5题。

材料一:历史地理学的起源至少可以追溯到我国最早的地理学著作《禹贡》。

这篇托名大禹的著作实际产生在战国后期。

《禹贡》虽以记载传说中的大禹治水后的地理状况为主,但也包含了对以往地理现象的追潮,含有历史地理学的成分。

成书于公元1世纪的《汉书·地理志》对见于典籍记载的重要地理要素,包括古国、历史政区、她名、河流、山岭、古迹等都做了记载和简要考证,并不局限于西汉一朝。

作者班固比较充分地利用己有的地理记载和地理研究成果,使得中国历史地理学研究初具雏形。

同样,成书于公元6世纪的《水经注》也从传世的数百种地理著作中搜集整理了大量史料,并做了深入的考证和研究。

今天,我们之所以还能知道先秦的某一个地名在现在的什么地方,能知道秦汉以降的疆域范围,能够大致了解黄河早期的几次改道,都离不开这两种著作。

在中国漫长的历史中,皇朝的更迭、政权的兴衰、疆域的盈缩、政区的分合和地名的更改不断发生;黄河下游及其支流的频繁决溢改道又经常引起有关地区地貌及水系的变迁,给社会生活带来相当大的影响。

中国古代繁荣的文化使这些变化大多得到了及时而详尽的记载,但由于在如此巨大的空间和时间中所发生的变化是如此复杂,已不是一般学者所能随意涉足,因而产生了一门专门学问——沿革地理。

沿革地理研究的内容关系有国计民生,也是治学的基础,例如历史她名的注释和考证、历代疆域和政区的变迁、黄河等水道的变迁,特别是与儒家经典和传统正史的理解有关的地理名称和地理知识,都被看成是治学的基本功。

在中国漫长的历史中,皇朝的更迭、政权的兴衰、疆城的盈缩、政区的分合和地名的更改不断发生;黄河下游及其支流的频繁决溢改道又经常引起有关地区地貌及水系的变迁,给社会生活带来相当大的影响。

中国古代繁荣的文化使这些变化大多得到了及时而详尽的记载,但由于在如此巨大的空间和时间中所发生的变化是如此复杂,已不是一般学者所能随意涉足,因而产生了一门专门学问——沿革地理。

沿革地理研究的内容关系到国计民生,也是治学的基础,例如历史地名的注释和考证、历代疆域和政区的变迁、黄河等水道的变迁,特别是与儒家经典和传统正史的理解有关的地理名称和地理知识,都被看成是治学的基本功。

沿革地理的成就在清代中期达到高峰,很多乾嘉学者致力于此。

但是沿革地理并不等于历史地理学,二者不仅有量的不同,而且有质的区别。

就研究内容而言,前者主要是疆域政区、地名和水道的变迁,后者却涉及地理学的各个分支。

就研究的性质而言,前者一般只是对现象的描述和复原,很少涉及变化的原因,后者则不仅要复原各种以往的地理现象,而且要寻找它们变化发展的原因,探索背后的规律。
