Many psychologists in the early twentieth century believed that humans use only

题型:不详难度:来源:
Many psychologists in the early twentieth century believed that humans use only 10 percent of their brains, and even the great Albert Einstein once wrote that most people use only a small portion of the grey matter between their ears. It’s a theory that has often been put forward in television documentaries; magazines, advertisements and books over the past century.
But nearly all scientists now agree the 10 percent theory is completely unfounded. In fact, they question how this figure was ever arrived at in the first place and what areas of the brain are supposed to be unneeded. The theory supposes that if 90 percent of the brain were removed, a person would Still be able to function normally, while in reality it is known that damage to even a small area of the brain can result in extremely serious physical injury different activities and that many areas of the brain are used at the same time for some complex activities or thought processes.
Throughout the course of one day, most .areas of the brain are active at some time, even during sleep. The 10 percent theory suggests that certain areas o’ the brain are not used, but scans slow activities throughout the entire brain and not in any separate part. The final argument against the 10 percent theory is the fact that doctors carefully map the brain before removing brain cancers so that they don’t affect other essential areas.
From an evolutionary point of view, it’s highly unlikely butt our comparatively larger brains would have evolved from our ancestors if the extra areas were not needed. In fact, there is absolutely no evidence support the 10 percent theory.
小题1:How did the 10 percent theory get such widespread popularity?
A.It was promoted in various types of copular media.
B.Albert Einstein argued strongly in support.
C.It was proven in scientific research.
D.Few people could prove it wrong.
小题2:The underlined word "unfounded" is chest in meaning to _________.
A.undiscoveredB.unprovenC.unknownD.unnecessary
小题3:Which of the following is true according to the writer?
A.We use less than 10% of our brains.
B.Most brain disorders affect the same part of the brain.
C.The brain is less active during times of sleep.
D.The 10 percent theory does not make evolutionary sense.
小题4:What can we infer from the passage?
A.People today use more of their brain than in the past.
B.Scientific opinion about the topic of brain use is equally divided.
C.Our understanding of the brain has changed greatly in the past decades.

举一反三
Every day Yang Hongwei takes the bus home from work, staring silently at the European-style villas(别墅), luxury cars and twinkling lights from the shopping center that he sees through the window.
Yang works for a software company in Zhongguancun. He dreams of such a life, away from poverty, and that hope has kept him in Beijing for three years since he graduated from university.
Soon Yang squeezes his way off the bus to the reality of his life: his home—a 10-square-metre room that costs 550 yuan(81 US dollars) or about one-fifth of his salary in rent every month. It’s very cold inside the house as it has no central heating system. He has to stand the long and cold winter. Determined to achieve his dream, Yang says he has changed jobs “numerous” times in the past three years and is considering quitting his present job.
Yang’s frustration over his life as a migrant(移民) is shared by many other graduates that have moved into big cities. Together they have come to be called the “ant tribe”, a term created by Chinese sociologists to describe the struggles of young migrants, who, armed with their diplomas, flood to big cities in hopes of a better life only to put up with low-paying jobs and poor living conditions. They share every similarity with ants. They live in colonies in crowded areas. They’re intelligent and hardworking, yet unknown and underpaid. The term, sociologists have said, also reflects their helplessness in a world governed by the law of the concrete jungle—only the strongest survive.
A survey in Ant TribeⅡ found nearly 30 percent of the “ants” are graduates of famous key universities—almost three times the percentage of 2009. Most have degrees in popular majors, such as medicine, engineering, economics and management. In addition, 7.2 percent of the “ants” have at least a master’s degree compared to 1.6 percent in 2009. Most said the economic recovery did not really improve their financial situations, and 66 percent said their incomes fell short of their expectations, the survey also found.
For two years, Lian Si, a post-doctoral fellow at the Center for Chinese and Global Affairs of Peking University, who has studied the phenomenon, led a team of more than 100 graduate students to follow the groups in university towns like Beijing, Shanghai, Guangzhou, Wuhan and Xi’an. Lian evaluates the total population of the “ant community” in major cities at one million across China, with about 100,000 found in Beijing alone. Lian predicts that an increasingly challenging job market will see the ant tribe growing further in number. Another 6.3 million graduates are expected to join migrant workers and other job hunters in what promises to be a fierce labour competition.
The ant tribe’s embarrassing living situations have become a serious social issue, and the government should develop “second-and-third-tier cities” to attract more graduates from big cities. However, “ants” expect more study and training opportunities in big cities, which keeps them in positive mindsets despite their situations. As in the case of Yang, he is optimistic about getting a new job soon, having received eight interview offers in a week after sending out his resume. The prospect of landing a higher-paying job keeps him hopeful of moving out of the slum district(贫民区) soon. The sooner the better.
小题1:. Yang has worked in Beijing since graduation from university ______.
A.to live in a beautiful villa of European style

“Eat local.” It’s one way to reduce human effect on the planet. Eating local means to try to buy and consume foods that are grown in places close to home. However, most of the food sold at supermarkets is not locally grown or produced. Trucks and planes deliver these foods from hundreds or thousands of miles away. During the transportation, greenhouse(温室)gases are produced, causing global warming. So the shorter the distance your foods must travel, the less the harm is done to the environment.
But how do you get local food if you live in a large city, hundreds of miles away from farms?Environmental health scientist Dickson Despommier and his students came up with the idea of a “vertical(垂直的)farm”.

A vertical farm is a glass-walled structure that could be built as tall as a skyscraper(摩天大楼). Since the garden is built upwards, rather than outwards, it requires much less space than an ordinary farm. The world is quickly running out of room for ordinary farming. Vertical farms could be a key to this situation. Despommier imagines a 30-story building with a greenhouse on every floor. The walls of the building would be clear, to allow crops to get as much sunlight as possible. Depending on a city’s water resources, Despommier thinks hydroponic(水培的) farming is another method for the vertical farm which needs no soil to grow plants.
Despommier says the hydroponic greenhouses would use a system that would use a city’s waste water and fill it with nutritions to make the crops grow. If this method works, it would provide food to a city and save millions of tons of water.
The idea of a vertical farm has attracted the attention of government officials around the world. Scott Stringer, a government official from New York City, thinks the city is suitable for the vertical farming. “Obviously we don’t have much land left for us,” Stringer said. “But the sky is the limit in Manhattan. ”
Despommier admits that there is still a lot of work to do to make vertical farms a reality. “But I think vertical farming is an idea that can work in a big way,” he says.
小题1:Why are people advised to eat local?
A.Because it means convenience(方便) to people.
B.Because it can help people save a lot of money.
C.Because local food has more nutrition.
D.Because it is environmentally friendly.
小题2:Which is one of the vertical farm’s benefits when compared with ordinary farming?
A.It produces healthier food.
B.It does less harm to the cities.
C.It needs less space of the city.
D.It requires less transport costs.
小题3:By saying “the sky is the limit in Manhattan”, Stringer means _____.
A.people can make full use of vertical space of Manhattan
B.there is a limit for using empty land in Manhattan
C.the height of buildings in Manhattan is limited
D.Manhattan can spread as far as possible
小题4:What can we learn about the vertical farming in the passage?
A.No soil is needed to grow plants in a vertical farm.
B.It has solved the problem of the food shortage in a big way.
C.It is a 30-story building with a greenhouse on every floor.
D.Crops are mainly grown in the rainwater in a vertical farm.

British English and American English are almost the same. But there are slight differences between British and American English in vocabulary, pronunciation, spelling and grammar.
The first difference between British and American English is in vocabulary. Almost all of the words used in British English and American English are exactly the same. Only a very small number of words are used disparately. For example, Americans would say “apartment”, but the British would say “flat” to talk about the place where they live. In addition to some common words, many idiomatic(惯用的)expressions are different. In England people might say “I’ll ring you up tonight”, but in the US, people might say “I’ll call you up tonight”.
The second difference between British and American English is in Pronunciation. The main difference in pronunciation concerns the vowels(元音). Some American dialects and some British dialects use vowels in different ways. Sometimes, Americans and the British don’t understand each other’s pronunciation. But most of the time, the British and Americans do understand each other’s pronunciation because most of the sounds of the two dialects are the same.
The third difference is very small. This is the difference in spelling. A few types of words are spelled differently in British and American English. The most common example is in a word like “center”. In British English, this word would be spelled C-E-N-T-R-E, while in American English the same word would be spelled C-E-N-T-E-R. Another example is “or” vs “our”. The word “color”is spelled C-O-L-O-U-R in Britain but C-O-L-O-R in the US.
There are a few differences in grammar, too. The British may say “Have you got..?” while Americans prefer “Do you have..?” An American might say “my friend just arrived”, but a British would say “my friend has just arrived”. Sometimes function words are used differently: the British may say “at the weekend”, but Americans would say “on the weekend”.
小题1:What is this passage mainly about?
A.The development of American English

It’s easy to see how to help others, but what about those whose needs aren’t so obvious? This story may have happened a while back, but it was a lesson which has stayed with me and helped me ever since.
It was Thanksgiving and I was volunteering with my parents at a shelter for the poor. We stood behind the counter dishing out hot food to whoever came in. most of our dinners looked like they had been having hard times, their clothes old, worn and dry. In short, they looked poor!
Then, a man came in, who looked anything but poor. He was well dressed, wearing an expensive suit. I wondered what he was doing there and my jaw dropped in amazement when he joined the line for food. The closer he came to my service station, the more I muttered. What was this man doing? I wanted to know. Surely he wasn’t gong to take food.
Then my mother quietly took me to one side. She said, “You have assumed that the needs of the people who come here must be purely physical: hunger, inadequate shelter and needs are emotional? What if he needs comfort, friends, or just to be among other human beings?” her words hit me like a ton of bricks! I felt like I should apologize to the man, but I didn’t.
About a week later the shelter received a large donation from an anonymous source. I can’t help but wonder if it came from that man.
Now, whether I meet others, I remember my mother’s words and try to send kindness and blessings to them, regardless of how they look.
Needs aren’t always visible. But kindness always makes a difference.

Mouse potatoes joined couch potatoes (who spend much time watching TV on the couch), google officially became a verb and drama queens (extremely emotional persons) finally found the attention when they crossed over from popular culture to mainstream English language.
The mouse potato, the himbo (attractive, empty-headed man) and drama queen were among 100 new words added to the 2006 update of America’s best-selling dictionary, the Merriam-Webster Collegiate Dictionary《韦氏大词典》. The Internet search engine Google also found its way into the dictionary for the first time as a verb, meaning to find information quickly on the worldwide web.
New words and phrases from the fields of science, technology, pop culture and industry are chosen each year by Merriam-Webster’s team of editors after months of looking through books, magazines and even food labels. “They are not tracking spoken language. They are looking for evidence that words have been used in the written English language,” said Arthur Bicknell, senior editor of Merriam-Webster.
Other words first coming into the dictionary this year were soul patch (a small growth of beard under a man’s lower lip), unibrow (two eyebrows joining together) and supersize - the fast food industry phrase for extra large meals.
The technology world contributed ringtones (changeable incoming cellphone call signals) and spyware (software installed in a computer to track a user’s activities) while biodiesel (生物柴油) and avian influenza(禽流感) came from the world of science.
America’s first dictionary - Noah Webster’s A Compendious Dictionary of the English Language - was published 200 years ago and also introduced some fresh words that have now become familiar. Those “new” words in 1806 included slang, surf, psychology, naturally and Americanize.
小题1:The mouse potato refers to ____________.
A.a mouse that lives by potatoes
B.a person who spends much time on the computer
C.a mouse that is shown on the screen of the computer
