Mass transportation revised the social and economic fabric of the American city in three fundamental ways. It catalyzed physical expansion, it sorted out people and land uses, and it accelerated the inherent instability of urban life. By opening vast areas of unoccupied land for residential expansion, the omnibuses, horse railways, commuter trains, and electric trolleys pulled settled regions outward two to four times more distant form city centers than they were in the premodern era. In 1850, for example, the borders of Boston lay scarcely two miles from the old business district; by the turn of the century the radius extended ten miles. Now those who could afford it could live far removed from the old city center and still commute there for work, shopping, and entertainment. The new accessibility of land around the periphery of almost every major city sparked an explosion of real estate development and fueled what we now know as urban sprawl. Between 1890 and 1920, for example, some 250,000 new residential lots were recorded within the borders of Chicago, most of them located in outlying areas. Over the same period, another 550,000 were plotted outside the city limits but within the metropolitan area. Anxious to take advantage of the possibilities of commuting, real estate developers added 800,000 potential building sites to the Chicago region in just thirty years – lots that could have housed five to six million people.
Of course, many were never occupied; there was always a huge surplus of subdivided, but vacant, land around Chicago and other cities. These excesses underscore a feature of residential expansion related to the growth of mass transportation: urban sprawl was essentially unplanned. It was carried out by thousands of small investors who paid little heed to coordinated land use or to future land users. Those who purchased and prepared land for residential purposes, particularly land near or outside city borders where transit lines and middle-class inhabitants were anticipated, did so to create demand as much as to respond to it. Chicago is a prime example of this process. Real estate subdivision there proceeded much faster than population growth.

解析写作方法与文章大意
文章论述了“公共交通从三方面改变了城市的社会和经济结构。”采用分类写法。文章一开始就提出三方面:第一,促进城市实质性的扩展;第二,把人和土地分民别类加以利用;第三,加速了城市生活的不稳定性。然后就是三方面的具体内容。
【小题1】D 公共交通运输对城市扩展的影响。文章开门见山提出这一点“公共交通运输从三个根本方面改变了美国城市的社会和经济结构。”后面文章内容就是三方面的具体化。
A. 公共交通运输类型。 B. 城市生活的不稳定性。 C. 供需如何决定土地利用。这三项文中作为具体问题提到,并不是文章涉及的主要题目。
【小题2】C 说明公共交通改变了许多城市。答案箭第一段第四句“举例说,1850年,波士顿市界离老的商业地区几乎不到2英里,到了这世纪末,其半径扩至10英里。现在供得起的人们可以住得很远,远离老的城市中心,仍然来回去那里上班、购物和娱乐”。第七句,“举例说,在1890至1920年期间,据记载,芝加哥市界内有约250,000个新的住宅楼区大多数设在郊区。经过同样这段时期,市区外,但仍在芝加哥大都市地区内,又计划建造了550,000个住宅楼区。”
A. 表示成长的正反两方面效果。B. 举有无公共交通运输的城市为例。 D. 对比两者成长率;都不是本文中举两城市例子的目的。
【小题3】C 没有计划。见第二段第三句起“城市扩展蔓延根本无计划,好几千个小的投资商进行扩展,毫不考虑相互协调配合利用土地,也不考虑未来土地利用。”
A. 太贵 和 B.太慢,两个选项,文内没有提。D. 它创造了对公共交通运输的需求。这不是住宅扩展的一个缺点,而是三个根本改变城市的一个方面。见第一段第三句:“通过大量开发未占土地扩建住宅,公共汽车、马车、铁路、来回火车,有轨电车把已有人定居的居住区向外扩展了三四倍,比他们先现代时期的市中心更远。”
【小题4】C(第二段中以芝加哥城市例子说明)土地开发超过人口增长速度。答案详见第二段“这些购买和置备土地建设住宅,特别是购置临近城市或就在市界外的土地,抢在交通线路和中产阶层的居民进去之前。他们这样做的目的是创造一种需求,也是响应这种需求。芝加哥就是这种过程的典型例子。那里的房地产小块土地比人口增长快得很多很多。”
A. 城市大。B. 用作土地开发的样板。 D. 具有优越的公共的交通系统。

If you think English means endless new words, difficult grammar and sometimes strange pronunciation, you are wrong. Haven’t you noticed that you have become smarter since you started to learn a language?
According to a new study by a British university, learning a second language can lead to an increase in your brain power. Researchers found that learning other languages changes grey matter. This is the area of the brain which processes information. It is similar to the way that exercise builds muscles.
The study also found the earlier people learn a second language, the greater the effect is.
A team led by Dr. Andrea Mechelli, from University College London(UCL), took a group of Britons who only spoke English. They were compared with a group of“early bilinguals(通两种语言的人)”, who had learnt a second language before the age of five, as well as a number of later learners.
Scans showed that grey matter density in the brain was greater in bilinguals than in people without a second language. But the longer a person waited before mastering a new language, the smaller the difference was.
“Our findings suggest that the structure of the brain is changed by the experience of learning a second language,”said the scientists.
It means that the change itself increases the ability to learn.
Professor Dylan Vaughan Jones of the University of Wales, has researched the link between bilingualism and maths skills.
“Having two languages gives you two windows on the world and makes the brain more flexible,”he said,“You are actually going beyond language and have a better understanding of different ideas.”
The findings were matched in a study of native Italian speakers who had learned English as a second language between the ages of 2 and 34. Reading, writing and comprehension were all tested. The results showed that the earlier they started to learn, the better.“Studying a language means you get an entrance to another world,”explained the scientists.
【小题1】What does the underlined part“grey matter”(in paragraph 2) refer to?
A.Grey hair. | B.Material of the brain. |
C.Intelligence. | D.Difficult situations. |
A.change one’s brain completely |
B.improve one’s maths skills |
C.make one smarter than others |
D.increase the ability to learn |
A.the researchers from UCL did another study in Italy |
B.a similar study was done on native Italian speakers who learn English as a second language |
C.the research done on the Italians showed a totally different result |
D.it will be easier for one to travel around the world by learning a second language |
A.Learning a second language can help improve your brain power. |
B.You should learn a second language in English that is not your native language. |
C.If you want to learn a second language, you should do it at a certain age. |
D.The research done by the researchers from UCL is very successful. |

Where do you find out about the world’s longest walk? The world's tallest man? The world's oldest woman? You know the answer, of course. It is the Guinness Book of World Records. How would people find such unusual facts without this book?
Guinness Book did not exist until 1951. Here is what happened. The managing director of Guinness Brewery was a curious man. He wanted answers to some questions about records. For example, he wanted to know what was the fastest flying game bird in Europe. But he was frustrated. There was no book to answer questions like this.
The director, Sir Hugh Beaver, contacted the McWhirter twins. They were brothers who owned a research agency. He asked them to put together a new reference book. It would include all kinds of unusual records. The brothers quickly accepted. The first edition of their book was published in 1955. Soon the Guinness Book of World Records was a best seller. It has sold more copies than any book except the Bible. A new edition is published every year.
Where do all the book's records come from? They are a combination of things like natural wonders, sports records, and stunts(特技) (How many people would push an egg with their noses if they weren’t trying to get to the book?). But the editors try to keep things honest. All records must be verified by an investigator. Only then are they printed.
The Guinness Book is a big business. It is published in dozens of languages. There are TV shows and museums. It is proof of how interested people are in strange pieces of information.
【小题1】The passage is mostly about _____.
A.the McWhirter twins |
B.the director Sir Hugh Beaver |
C.unusual records in the Guinness Book |
D.a history of the Guinness Book |
A.is a best seller |
B.is published only in English |
C.does not always check its records |
D.has a full-length movie based on it |
A.wanted to publish the book so that they set up a research agency |
B.owned so good a research agency that they liked to help others |
C.recognizes that Sir Hugh's idea for a book was a good one |
D.wanted to know the answers to some questions about records |
A.questioned | B.proved the truth | C.written up | D.blocked |

“Enough” with the multivitamins already. That’s the message from experts behind three new studies that tackled an often debated question: Do daily multivitamins多种维生素make you healthier?
“We believe that the case is closed - supplementing(补充) the diet of well-nourished adults with (most) mineral or vitamin supplements has no clear benefit and might even be harmful,” concluded the authors of the editorial summarizing the new research papers. They urge consumers to not ‘waste’ their money on multivitamins. “The ‘stop wasting your money’ means that perhaps you’re spending money on things that won’t protect you long term,” editorial co-author, Dr. Edgar Miller said, “What will protect you is if you spend the money on fruits, vegetables, nuts, beans, low fat dairy, and things like that. Exercising would probably be a better use of the money.”
The strong message was based on a review of the findings from three studies that tracked multivitamins link to cancer protection, heart health, and brain and cognitive(认知的) measures. The first study looked at vitamin supplementation’s role in preventing chronic(慢性的) disease. The next study looked at whether long-term use of multivitamins would have any effect on slowing cognitive decline. The third study looked specifically at multivitamins and minerals role in preventing heart attack. “The three studies found no difference in rates of chronic disease, heart attack and the need for hospitalization between vitamin-takers and placebo(安慰剂)-takers.” Dr. Edgar Miller stated.
One expert agreed some nutrient-deficient people may still benefit from multivitamins. “There might be an argument to continue taking a multi(vitamin) to replace or supplement your not healthy diet,” Dr. Edgar Miller added. He also notes that vitamins can benefit people with celiac disease and those who are pregnant.
【小题1】This text is likely to be selected from a book of .
A.medicine | B.education | C.food | D.business |
A.Vitamins should not be used for chronic disease prevention. Enough is enough. |
B.Having a balanced diet and exercising would probably be a better way to keep healthy. |
C.The three studies do not provide support for use of multivitamin supplements. |
D.Taking vitamins to replace or supplement your healthy diet is necessary. |
A.Vitamin supplements have proved harmful to the health of adults. |
B.Vitamin supplements are beneficial in certain conditions. |
C.Nowadays taking vitamin supplements is common to most people. |
D.Daily multivitamins will make you healthier. |

Pilling a cat can be a 'terrible” experience. Cats don’t want something pushed down their throats, and they’ll fight with all their strength to prevent it. In fact, it’s amazing how powerful their small bodies can be.
The easiest way of pilling a cat is to press the pill into powder. Then mix the powder with a small amount of wet food. If your cat usually eats dry food, she will probably view the wet food as a treat and eat it up.
If your cat won’t eat the wet food that contains the pill or if she is too ill to eat, you can get a “pill gun”. There are some basic instructions. Getting your cat’s mouth to open is going to be the most difficult part. First, be sure the pill is in a handy place. Then you can put your cat on a bookshelf with her bottom in a corner or you can put her on your lap firmly tied. Have your cat facing to the right if you’re right-handed. With your left hand, hold your cat at the cheekbones, putting your palm (手掌) at the top of her head. Keeping your finger off the trigger (扳机), with your right hand, Insert the pill gun until the pill is positioned over the tongue and open throat Be sure to give your cat a treat directly after giving the pill.
If you don’t feel comfortable using a pill gun, you can try giving the pill by hand. Push your cat’s head backwards just far enough so that her nose is pointing towards the ceiling. At this point, most cats will slightly open their mouths. With the little finger or ring finger of the hand holding the pill, open the bottom jaw a little more. You may need to hold her top jaw with your other hand while doing this. Aim straight and lightly throw the pill or drop it. Most cats will then swallow the pill.
【小题1】Pilling a cat can be a terrible experience because cats ______.
A.are amazingly powerful and dangerous |
B.may fight with all their strength against pills |
C.refuse something pressed down their throats |
D.are difficult to treat once they’ve got ill |
A.Wet food with medicine is usually a treat to cats. |
B.Cats used to dry food must reject wet food. |
C.The easiest pilling is to press the pill into powder. |
D.Cats arc most likely interested in something new. |
A.facing to the right | B.with your right hand |
C.at the head | D.on your lap firmly |
A.its nose is straight upwards | B.it is touched by fingers |
C.its head is turning around | D.it is served with its favorite pills |

Global warming happens when greenhouse gases trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. This is like when heat is trapped in a car. On a hot day, the car gets hotter when it is out in the parking lot. This is because the heat and light from the sun can get into the car, by going through the windows,but it can’t get back out. This is what the greenhouse effect does to the earth .The heat and light can get through the atmosphere, but it can’t get out As a result,the temperature rises.
Sometimes the temperature can change in a way that helps us. The greenhouse effect makes the earth appropriate for people to live on Without it,the earth would be freezing,or it would be burning hot. It would be freezing at night because we would not get the sun’s heat and light .During the day, especially during the summer, it would be burning because the sun would be up with no atmosphere to filter(过滤)it,so people,plants,and animals would be exposed to all the light and heat.
Although the greenhouse effect makes the earth able to have people living on it,if there gets to be too many gases,the each can get unusually warmer, and many plants,animals.and people will die. Plants would die because they would not be able to take the heat .This would cause us to have less food to eat, and it would also limit the food that animals have. With less food for the animals that we need to survive we would even have less food. Gradually, people,plants,and animals would all die of hunger.
People are doing many things to try to stop global warming .One thing is carpooling—driving with someone to a place that you are both going to. Another thing is being more careful about leaving electrical devices turned on. Now, more people are even riding buses or bikes to lower the amount of greenhouse gases in the air .Although adults do many things to help stop global warming, kids call do just as much.
【小题1】By the example given in Paragraph l, the author wants to__________.
A.explain how global warming happens |
B.show his feeling in a car in hot summer |
C.tell us cars are causes of greenhouse gases |
D.say that I there are greenhouse gases in every car |
A.light | B.greenhouse effect | C.temperature | D.heat |
A.IT only traps the heat of the sun. |
B.It does great harm to humans. |
C.It makes the earth neither to hot nor too cold. |
D.It prevents all the light from the sun shining on the earth. |
A.lf there is greenhouse effect.all the plants will die |
B.Human beings are likely to disappear from the earth |
C.Crops can ′t take in the heat lf there is greenhouse effect |
D.Although greenhouse effect is necessary.Too much of it will cause us to die. |

Almost every machine with moving parts has wheels,yet no one knows exactly when the first wheel was invented or what it was used for.We do know,however,that they existed over 5,500 years ago in ancient Asia.
The oldest known transport wheel was discovered in 2002 in Slovenia.It is over 5,100 years old.Evidence suggests that wheels for transport didn’t become popular for a while,though.This could be because animals did a perfectly good job of carrying farming tools and humans around.
But it could also be because of a difficult situation.While wheels need to roll on smooth surfaces,roads with smooth surfaces weren’t going to be constructed until there was plenty of demand for them.Eventually,road surfaces did become smoother,but this difficult situation appeared again a few centuries later.There had been no important changes in wheel and vehicle design before the arrival of modern road design.
In the mid1700s,a Frenchman came up with a new design of road—a base layer(层) of large stones covered with a thin layer of smaller stones.A Scotsman improved on this design in the 1820s and a strong,lasting road surface became a reality.At around the same time,metal hubs (the central part of a wheel)came into being,followed by the pneumatic tyre(充气轮胎) in 1846.Alloy wheels were invented in 1967,sixty years after the appearance of tarmacked roads(柏油路).As wheel design took off,vehicles got faster and faster. (2013·重庆,C)
【小题1】What might explain why transport wheels didn’t become popular for some time?
A.Few knew how to use transport wheels. |
B.Humans carried farming tools just as well. |
C.Animals were a good means of transport. |
D.The existence of transport wheels was not known. |
A.It was easier than wheel design. |
B.It improved after big changes in vehicle design. |
C.It was promoted by fastmoving vehicles. |
D.It provided conditions for wheel design to develop. |
A.By giving examples. |

Rising levels of carbon dioxide in the atmosphere are a major cause of climate change, and now a new study has confirmed that atmospheric CO2 is also affecting the ocean chemistry and potentially harming sea life.
Montana State University scientist Robert Dore has been researching the water in the Pacific Ocean for almost two decades. "We've been going to the same spot in the Pacific Ocean, and we try and characterize long-term change in the open ocean environment. And one of the key things that we measure is COx levels. And We've been able to record this increasing quantity of atmospheric CO, into the ocean. "Scientists expected that as atmospheric CO2 increased, more and一 more of the carbon dioxide would be absorbed into the ocean, affecting the chemical balance of the sea water, with a potentially harmful impact on shellfish and coral in particular.
"As carbon dioxide dissolves in the water, or seawater in this case, it forms a weak acid, carbonic acid," Dore explains. "And therefore, as the concentration of CO2 in the atmosphere goes up and that exchanges with the surface seawater, it drives the pH down, and makes it more acidic."
The seawater samples Dow and his colleagues have analyzed confirm what the theory predicts. The effect was particular striking at about 250 meters down, and again at 500 meters. Dore and his colleagues came up with two possible explanations. It could be that surface water picked up CO2 and then moved to those depths. Or there could be a biological explanation.
"It's important to realize that the oceans are really becoming acidic. And it can have negative impacts on a whole variety of sea life from fish to coral. It’s potentially catastrophic."
【小题1】What can be the best title of the passage?
A.Sea Life Facing Danger | B.Scientist Researching Seawater |

Special trees that grow faster, fight pollution, produce better wood, and even sense chemical attacks are being planted by scientists in the US.
When 40 per cent of Hawaii's US$14 million-a-year papaya (木瓜)industry was destroyed by a virus five years ago, work began on creating genetically engineered(转基因的)trees.
Researchers successfully introduced seeds that were designed to resist the virus.Since then, more and more people have been testing genetically engineered trees.Some researchers put special bacteria into trees to help them grow faster and produce better wood.Others are trying to create trees that can clean polluted soil.Meanwhile fruit farmers are looking for trees that are strong enough to resist worms, and paper companies want trees that produce more wood and therefore more paper.
The Pentagon (五角大楼) even gave the researchers US$500,000 this year after they developed a pine tree that changes its colours if it senses a chemical attack.So far, the poplar, eucalyptus (杨树与桉树), apple and coffee trees are among those being engineered.All this can be done today because we have a better understanding of tree genomes (基因组).
However, some people fear that the genetically engineered trees will cause dangerous results.They are worried that the new trees will breed with natural species and change the balance of the forest environment.
“It could be destructive,” said Jim Diamond, an environmentalist. “Trees are what is left of our natural environment and home to many endangered species.”
But researchers insist that science could give nature a fighting chance against both natural and man-made dangers.They hope to answer the critics by stopping the new trees from breeding, so their effect on the environment can be controlled.
【小题1】Which kind of tree is not the ones that scientists are planting in the US?
A.Trees that worms can't hurt. |
B.Genetically engineered trees. |
C.Trees that can resist wind better. |
D.Trees that can protect themselves at a chemical attack. |
A.Tree genomes are mapped out so scientists know how to improve trees. |
B.Great numbers of trees have been lost due to attacks by viruses. |
C.Researchers successfully introduced seeds designed to resist the virus. |
D.They think science could give nature a fighting chance against both natural and man-made dangers. |
A.Papaya. | B.Pine. | C.Apple. | D.Poplar. |
A.these trees can destroy the balance of nature |
B.everything except trees has been genetically engineered |
C.trees are home to many endangered species |
D.these trees may affect normal trees |
