A study suggests that although most students at UK universities are happy with their courses, dissatisfaction has grown as fees rise．The study highlights a big variation in teaching time, and lists different ideas about the value of getting university degrees．
Katharine Collins, a second-year college student
The course has been very interesting, but I was expecting a little more one-to-one time with my teacher．
We do about four assignments （作業） each term, each of which is about 3,000 words．However, sometimes they are not that helpful．We hope to be given the right to write feedback （反饋） after every assignment, but we had no feedback at all throughout the first year．We are given grades about three weeks after we hand the assignments in．There is no feedback on where we have gone wrong or how we might improve．
Lee Millington, a creative-writing student
I choose the courses because of its reputation．There is a lack of one-to-one teaching．I would like personalized feedback from an expert in my field of writing．Some of the lectures have been quite helpful but they try to use too many different styles of writing．For example, if you want to be a poet, you might find that the lectures focus too much on novels．
I think there is too much attention paid to sharing our work in workshops and giving each other feedback．I think there should be more time given to actual teaching, rather than to feedback from people who are at a similar level to me．
Reporters from Hounsdown Secondary School, Ella, 16
When I work independently, I feel I have more freedom to develop my ideas and come up with more original viewpoints．The price of university will still be worth it to get the qualifications （資格證書）necessary for better jobs．
Tyier, 16
Although the cost of university is very high now, I think university is required for gaining a good and well-paid job．

Two­thirds of the world's major rivers have now been disrupted with more than 50,000 dams in an attempt to  store water and provide power.In the US，there are more than 85,000 dams，disrupting large and small rivers，and in most cases transforming natural flow.The most famous of these，the Hoover Dam，constructed in the 1930s，is mainly responsible for the fact that the Colorado River no longer reaches the ocean.
Dams，besides all their attractive benefits，also have negative impacts.Creating a reservoir means a large area must be flooded.Communities may lose their land，houses and culturally important sites.
Environmentally，the new reservoir can be a paradise for wildlife，especially birds；however，it can cause greenhouse gas emissions and poison the water.Also，the dramatic rise and fall of water levels during dam releases is too extreme for plants and animals to cope with，resulting in dead zones around the shores of reservoirs.Fish that lay their eggs in the shallows，for example，may find a few hours later that those sites are high and dry.
Downstream(在下游方向)of a dam，the flow may be reduced so that farmers cannot irrigate their fields.Many rivers run through national borders，which may cause conflict over precious water.Disputes have been continuing between India and Pakistan，and Turkey，Syria and Iraq，for example.
Dams don't just block the flow of water.They also prevent fish migrations，and dams are a barrier to sediment(沉淀物)flows.Instead of rushing downriver，sediments get backed up against the dam wall，which causes the reservoir level to increase over time.However，sediments which are rich in nutrients have become a problem.The fertility of the entire system can be influenced，with soils lost during seasonal rains not being replaced.
Perhaps the biggest problem can be seen in deltas，which are sinking into the oceans.Groundwater is being extracted to feed the city，causing the city to sink，and sediments washed away by the ocean are no longer being replaced.The result is that sea level rises in cities from Shanghai to Alexandria.
小題1:The Hoover Dam is mentioned in the passage in order to show________.
A．dams play an important role in our life
B．dams have impacted the flow of the rivers
C．dams make people lose their land and houses
D．dams have many benefits as well as side effects
小題2:What effects does creating a reservoir have on people's life?
a．People will see fewer birds on the sides of the rivers.
b．Farmers will have less water to irrigate their fields.
c．Visitors can't visit some cultural relics any more.
d．More conflicts and wars over water will break out.
e．More kinds of fish will become extinct in future.
A．a，c　B．c，e
C．b，e　D．b，c
小題3:With many dams built across the rivers，fish ________.
A．will find more places to lay their eggs
B．will face a dangerous habitat
C．will be fed on more sediments rich in nutrients
D．will find it easier to deal with the rise of water
小題4:How can dams influence large cities like Shanghai?
A．Their entire system will be influenced.
B．The rainy season will last longer.
C．They will lie below sea level in future.
D．Rich soils will be washed away.
小題5:What does the passage mainly talk about?
A．Environmental loss of dams.
B．Cultural loss of dams.
C．Economic gain of dams.
D．Environmental benefits of dams.

  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.
小題1:With which of the following subjects is the passage mainly concerned?
[A] Types of mass transportation.
[B] Instability of urban life.
[C] How supply and demand determine land use.
[D] The effect of mass transportation on urban expansion.
小題2:Why does the author mention both Boston and Chicago?
[A] To demonstrate positive and negative effects of growth.
[B] To exemplify cities with and without mass transportation.
[C] To show mass transportation changed many cities.
[D] To contrast their rate of growth.
小題3:According to the passage, what was one disadvantage of residential expansion?
[A] It was expensive.
[B] It happened too slowly.
[C] It was unplanned.
[D] It created a demand for public transportation.
小題4:The author mentions Chicago in the second paragraph as an example of a city,
[A] that is large.
[B] that is used as a model for land development.
[C] where the development of land exceeded population growth.
[D] with an excellent mass transportation system.

Even while in a deep sleep, people can still learn brand new information. Sleepers soak in new associations between smells and sounds, knowledge that lingers(逗留）into the next waking day, researchers report online August 26 in Nature Neuroscience.
The new study is the first to show that entirely new information can get into the sleeping mind, says Anat Arzi of the Weizmann Institute of Science in Israel. "The brain is not passive while you sleep. It's quite active. You can do quite a lot of things while you are asleep."
But the results don't mean that Spanish vocabulary tapes now have a place on the nightstand. L, Researchers have tried but largely failed to find evidence that complicated information, such as new pairs of words, can make its way into the brain during sleep.
Instead of trying to teach people something complicated like a new language, Arzi and her colleagues relied on the sense of smell and hearing. As anyone who has walked by a dumpster（垃圾車）in July knows, smells can cause a nose-jerk reaction. Catching a bad smell automatically makes people inhale(吸氣)less, reducing the size of the inhale. But scent of fresh bread causes a long, deep inhale.、rzi and her team took advantage of this reaction for their experiment.
As people slept in the laboratory, the researchers delivered pleasant scent, such as shampoo. As this nice smell got into the sleepers' noses, the researchers played a particular music. Later, a disgusting smell, such as rotten fish or meat, was paired with a different music. Neither the smell nor the sound woke people up. After just four exposures to the smell-music pair during a single night, the sleepers started to automatically respond to the tones without the accompanying smells, taking in bigger breaths when the shampoo-associated tone played and smaller breaths when played the sound linked to the rotten fish smell.
This new learned association lingered into the next waking day, too. Even though the sleepers had no idea they had been exposed to smells or sounds, their behavior proved that their brain had actually learned something during sleep. As before, the shampoo sound stimulated a long, deep inhale, while the rotten fish tone caused more shallow breaths.
小題1:We can infer from the passage that
A．while sleeping, we can learn whatever we want to learn
B．we will increase the size of inhale if we catch a pleasant smell
C．the knowledge we learned while sleeping will be forgotten in the next waken day
D．when walking by a bakery, the fresh bread will cause a nose-jerk reaction
小題2:What is Paragraph 3 mainly about?
A．One can’t acquire complicated knowledge during the sleeping hours.
B．Spanish vocabulary tapes now have a place on the nightstand
C．Researchers have tried to find evidence that the new words can be learned during sleep.
D．Complicated information can make its way into the brain during sleep
小題3:How do Arzi and her team do their research? By
A．giving instructionsB．analyzing human brains
C．following the guides of othersD．doing experiments
小題4:In which part of a website may this passage most likely appear?
A．Culture.B．Science.C．History.D．Economy.

Across the United States, universities and colleges have been looking to become more sustainable (可持續發展的) and more than 600 schools have already planned to become eco-friendly. The EcoDorm, home to 36 students at Warren Wilson College in Swannanoa, was designed to be sustainable from top to bottom, or in this case, from its rainwater-collection system to its garden. The dormitory is bringing new meaning to the concept of living “green” at college.
At Warren Wilson College, a biological science school with fewer than 1,000 students, the sustainability drive came from the student body. The EcoDorm concept was presented ten years ago by two students; a planning committee firstly suggested using building materials like corncob. Although the architects disagreed with the idea, they came up with other creative solutions: Wood siding was taken from the trees grown in the school yard that were suffering from a disease, and rainwater was collected in an old railway car and pumped back into the house to clean the toilets.
All in all, the dorm uses nearly two-thirds less electricity than a similar-sized traditional building would. But even the most sustainable homes need continued efforts from its livers. And in the case of EcoDorm, students live by their words. Most also take advantage of the dorm’s bio-garden, planting and harvesting fruits and vegetables. “I didn’t have to worry about paper towels being wasted or feel bad about drying my clothes outside,” Jeremy Lekich, the dorm’s gardener, said. “Basically, it has made my life easier.”
小題1:We can learn from the text that the EcoDorm in the US     .
A．offers students the chances to have a natural living at college
B．was firstly built by two college students
C．was designed for saving building materials
D．is only applicable in few schools
小題2:The second paragraph is mainly about     .
A．where the EcoDorm was built
B．when the EcoDorm got its name
C．what the EcoDorm is made of
D．how the concept of EcoDorm started
小題3:What is the advantage of the EcoDorm?
A．It helps students to enjoy life at college.
B．It saves a lot of money and energy for the college.
C．It makes students study harder.
D．It brings new energy to the college.
小題4:What can be inferred from the text?
A．A long-term development calls for students’ efforts.
B．Students’ ideas should be encouraged at college.
C．Green living is a new trend at American colleges.
D．Students can learn to protect the environment through practice.

It's going to be a chaotic(混亂的)day. How do I know? It’s Monday. OK, joking. But, I do predict that today will be filled with the normal last-minute tasks, fire drills, and unforeseen events. So, how do you keep yourself from being swept away in the stream of chaos? How do you remain calm while others are rushing and panicking? There's a problem… Panic! When things don't go as planned, how do you react? Are you the calm one who works to fix things? Or the one running around like Chicken Little screaming that the sky falling? Getting upset or alarmed can seem like natural reactions to a problem.
Here are a few tips to kelp you remain calm in the face of the storm:
? Don't Panic  You are better able to find a solution if you   aren't panicking. If you can keep your head when others are losing theirs, you will be able to make a dear decision in the chaos.
? There Aren't Many True Emergenaes   My time as a Naval Officer taught me a­bout true emergencies. In the military, when there is a problem, people can get hurt or die. This is not usually the case when the office copier or email server goes down. Keep things in perspective. There are very few true emergencies in life.
? Avoid the "Fight or Flight"   When you are stressed, your body will want to go into "fight or flight." Your body was designed to keep you safe from danger, but its natu­ral reflexes aren't always the best solution against a project gone away. Keep your emotions in check and ensure that your physical reflexes don’t make bad decisions for you.
? Head Into The Problem    While everyone else is running away, true leaders walk into a problem. Sticking your head in the sand only makes things worse. Instead of trying to ignore the situition, get to the heart of the issue as soon as possible. Only then can you address it
How Will You React? When you find yourself ready to lose it, take a step back. Ask, "In this truly an emergcncy?" Keep your head when others are losing theirs. And you'll find that you are that much closer to a solution.
小題1:The author writes the first paragraph in order to______.
A．describe a chaotic dayB．advocate a way of lifeC．introduce a topicD．make a joke
小題2:In order to make a wiser decision in the chaos, you should _____.
A．low your headB．keep your headC．shake your headD．stick your head
小題3:The example of the author's time as a Naval Officer is used to illustrate_____.
A．there are seldom true emergencies in life
B．there are many true emergencies in life
C．some emergencies are really urgent
D．some emergencies can't be predicted
小題4:What would the best title for the passage?
A．Fight or Flight
B．True emergencies
C．Less Talking, More Doing
D．Keep calm in the face of the storm

Way back in 1662，John Evelyn，a brilliant Englishman known for his detailed diaries，wrote about disastrous effects of coal-burning on the city of London .In it,he described an infernal scene of smog．air filled with “Columns and Clouds of Smoke’’given out by small industries and residences that burned coal for fuel．
I found the description in the 2003 book When Smoke Ran like Water，by epidemiologist(流行病學家)and environmental advocator(倡導者)Devra Davis．In it,Davis looks back at several historic pollution events and their disastrous effect on human human health-and at how these phenomena were often Ignored or even actively covered up by then people in charge at that time.

not pan out．
Davis writes that even today in this country ,we still have not completely absorbed the lessons of similar events．Sixty years the killer fog lifted in London，people are dying preventable deaths and suffering life．changing illnesses，simply because they must breathe the air of the cities where they live

One might expect that the ever­growing demands of the tourist trade would bring nothing but good for the countries that receive the holiday­makers. Indeed, a rosy picture is painted for the long­term future of the holiday industry. Every month sees the building of a new hotel somewhere. And every month another rock­bound Pacific island is advertised as the ‘last paradise(天堂) on earth’．
However, the scale and speed of this growth seem set to destroy the very things tourists want to enjoy. In those countries where there was a rush to make quick money out of sea­side holidays, over­crowded beaches and the concrete jungles of endless hotels have begun to lose their appeal.
Those countries with little experience of tourism can suffer most. In recent years, Nepal set out to attract foreign visitors to fund developments in health and education. Its forests, full of wildlife and rare flowers, were offered to tourists as one more untouched paradise. In fact, the nature all too soon felt the effects of thousands of holiday­makers traveling through the forest land. Ancient tracks became major routes for the walkers, with the consequent exploitation of precious trees and plants.
Not only can the environment of a country suffer from the sudden growth of tourism. The people as well rapidly feel its effects. Farmland makes way for hotels, roads and airports; the old way of life goes. The one­time farmer is now the servant of some multi­national organization; he is no longer his own master. Once it was his back that bore the pain; now it is his smile that is exploited. No doubt he wonders whether he wasn't happier in his village working his own land.
Thankfully, the tourist industry is waking up to the responsibilities it has towards those countries that receive its customers. The protection of wildlife and the creation of national parks go hand in hand with tourist development and in fact obtain financial support from tourist companies. At the same time, tourists are being encouraged to respect not only the countryside they visit but also its people.
The way tourism is handled in the next ten years will decide its fate and that of the countries we all want to visit. Their needs and problems are more important than those of the tourist companies. Increased understanding in planning world­wide tourism can preserve the market for these companies. If not, in a few years' time the very things that attract tourists now may well have been destroyed.
小題1:What does the author indicate in the last sentence of Paragraph 1?
A．The Pacific island is a paradise.
B．The Pacific island is worth visiting.
C．The advertisement is not convincing.
D．The advertisement is not impressive.
小題2:The example of Nepal is used to suggest ________.
A．its natural resources are untouched
B．its forests are exploited for farmland
C．it develops well in health and education
D．it suffers from the heavy flow of tourists
小題3:What can we learn about the farmers from Paragraph 4?
A．They are happy to work their own lands.
B．They have to please the tourists for a living.
C．They have to struggle for their independence.
D．They are proud of working in multi­national organizations.
小題4:Which of the following determines the future of tourism?
A．The number of tourists.
B．The improvement of services.
C．The promotion of new products.
D．The management of tourism.
