Prompt:
The German city of Hamburg has announced plans to become car-free within the next two decades. It is an ambitious idea, but city officials obviously feel that the personal motorcar does not fulfill a function that walking, biking and taking public transport cannot. The goal of Hamburg's project is to replace roads with a green network, which will allow people to navigate through the city without the use of cars.     Banishing the car from urban areas is becoming a common trend in many European cities. London imposes a "congestion charge" on private vehicles entering the city centre during rush hours. Copenhagen is building bicycle superhighways radiating out from the city centre. These developments combined may make worrying reading for driving enthusiasts. Is the time of the personal car over?      In the century since the Ford Model T was introduced in 1908, global vehicle numbers have swollen to well over a billion. But according to recent research, the growth may have stopped.     According to Professor Michael Sivak, at the University of Michigan, "motorization" in the US might have reached a peak in 2008, and that the figures have been on the decline since.      "New York, Washington, Boston, Philadelphia, each have more than thirty percent of households without a light duty vehicle," says Sivak. In fact, the figures show that fifty-six percent of households in New York (which top the list) don't have a car. "I think that will be surprising to most people. It was surprising to me, and I am in the business. "       Sivak thinks a number of factors could be contributing to the trend, including workingfrom home and the movement of populations back to city centers. In China, Beijing and Shanghai are looking at plans to limit the number of new vehicles being registered to control prouth. It's a movement more cities are looking towards, particularly in the US. Why does Hamburg launch the "car-free" program?

Choices:
A. To build a greener environment.
B. To fix a worldwide road network.
C. To call on people to take exercise.
D. To replace the public transport.

I used to hate my mother because she worked a lot and didn't spend much time with me. Then one Friday morning I took part in a three-day self-help program for teenagers. Whether you believe it or not, that weekend changed my life. About 100 other teenagers were there. During the first two days I met a lot of great people. I was glad because I made so many friends there. On Sunday, the leader did an interesting exercise called "Chocolate or Toys". He asked a girl which she liked better, chocolate or toys. She chose chocolate. Then he asked her to choose again between chocolate and chocolate. Of course, she didn't have a choice. This exercise told us that sometimes we don't have a choice in life, and that sometimes we have to accept something, rather than complaining . A girl stood up and started talking about her mom who was a drug addict  and how much she hated her mother. "I want a new mom," she cried. "Unluckily, you can't have one," the leader replied. "You have to accept the mother that you have." This hit me hard. I realized that, for better or worse, my mom was my mom. I couldn't choose another mom, but I could try to make the best of the situation. The writer started to change his thinking   _  .

Choices:
A. during the first two days of the program
B. after the exercise named "Chocolate or Toys"
C. as soon as he came to the program
D. after he left the program some time

Good evening, ladies and gentlemen. I'm Roy Darby, and this is my show. This is a television show for all the families and I know you're going to enjoy it. Let's start with a story I heard the other day about a very proud pig. This pig lived on a farm with a lot of other animals. And of all the animals on the farm, he thought he was the most important. But it was not enough that he himself thought this way. He had to be sure that the other animals thought so, too. So he went up to one of the chickens and asked, "Who is the most important animal on the farm?" Straight away, the chicken answered, "You're, Master." Then he asked one of the farm dogs and he got the same reply. Next, he asked a cow. When the cow seemed uncertain of the right answer, the pig looked angry and showed his teeth. "Oh, you are, of course, Master Pig," said the cow. "Of course," the pig said. "There is no doubt about it." At last, the pig asked a big horse, "Who is the most important animal on the farm?" The horse lifted one foot, rolled the pig over, and placed his foot on the pig's head. "All right," said the pig, "you don't have to do that just because you don't know the answer." The dog   _  .

Choices:
A. answered in the same way as the chicken
B. did not understand the question

Do you know the open-air art gallery in London's Blackall Street? Probably -not. Not many  Londoners know it either, but Henri does and he is willing to show it to you. Henri used to sleep in parks until he met a charity  that helps homeless people get  back on their feet by becoming tour guides. Rather than show traditional London sights, "Unseen Tours" t _ Henri has been teaching tourists about the history and architecture of Shoreditch, where he slept on public benches for three years. When he felt separated from the society, contact with the volunteer network "The Sock Mob" gave Henri hope. "Not everyone just looked down on me," he said. The tours aren't the only actions trying to help those who have suffered a misfortune to stand tall again. An innovative  college for homeless people in London, the first of its kind in the country, is attracting hundreds of students. The Recovery College, set up by St Mungo's charity, is providing courses designed to improve technical skills and life skills. According to Andy Williams, who helps to organize the college, the most popular courses have proved to be about raising self-confidence and developing self-pride. Steve, now in his 50s, told a reporter how much of a difference it makes to "have a bit of confidence". He had difficulty learning to read and had to leave school when he was 12. Because Steve's problem was not recognized at the time, he was "seen to be unable to read or write", and suffered with depression and alcohol addiction. He says the status of "student" is itself important for people who are used to being treated as outcasts  Some charities aim not only to help the homeless become independent but also to make them popular. The Homeless World Cup started ten years ago. Today the tournament draws teams from 48 countries made up of players-men and women-who are, or have been, living in the streets.  It gives them a chance to become football heroes. At the age of 12, Steve   _   .

Prompt:
FOR most people, life without plants is unimaginable. They feed us, clean up our air and brighten up our gardens. But what if someone told you that even our smartphones can benefit from plants? Meet the scientists from the Freiburg University of Mining and Technology in Germany. According to reports from Reuters, they have come up with a way to take the important element germanium   from plants. The element was first discovered in Germany (hence the name) and was used to develop the first transistor   because it can transport electricity very quickly. Nowadays, silicon-germanium alloy   plays an important role in making computers, smartphones and fiber-optic cables  . Although germanium can be found in soil around the world, it is difficult to extract  . In the traditional process, people take the material after zinc   mining or burning coal. But the Freiburg scientists decided to fall back on the natural world. Biology professor Hermann Heilmeier is one of the scientists who are using common plants for this uncommon process. "Different energy crops are being planted, for example, sunflowers, corn ... we want to use them for phytomining. In German we call it 'mining with plants'." Others have used this method in the past with metals like gold and copper  . But in their study, the Freiburg scientists brought germanium from the soil into the roots and shoots of the plants, harvested them and then took the element from the plants. The process did not cost too much because germanium can be taken after plants are processed for use as biogas  . So many of the costs are already covered in existing biogas plants. However, there is still a lot of work to do before we can all experience the benefits. At the moment germanium can only be harvested in very small amounts, just a few milligrams per liter. Now scientists are working on different plants to improve this. "As is so often the case, industry is still waiting because they want to see everything already working. Then they say, 'We'll have it.' But of course we have to complete the step in between first," said Professor Martin Bertau, head of industrial chemistry at Freiburg University. We can learn from the article that germanium   _  .

Choices:
A. is mostly produced in Germany
B. can effectively transfer electricity
C. exists mostly in soil and water
D. is very easy to get from nature

On a hot summer day, ice-cold watermelons serve up a delicious treat. Sure, the rosy flesh   quenches your thirst  . But now there are more reasons than ever for people to reach for a slice of watermelon. Meet Dr Alison Edwards. She is a scientist at the Agricultural Research Service. Scientists are people who come up with new ideas called theories  . They usually do scientific research to test their new theories. That's how they find out if a new idea is a good one, or if the new idea will bring an even better idea. At her lab, Dr Edwards recently learned more about the secrets of why watermelons are good for you! Dr Edwards has known for a long time that watermelons have vitamin C. But recently she learned that watermelons also have lycopene  . It is something that gives tomatoes and watermelons their rosy red colour. What's so special about the lycopene in watermelons? Dr Edwards says that watermelons and tomatoes both have lots of lycopene. It seems that your body can use the lycopene from watermelons more easily than the lycopene from raw   tomatoes. In fact, the lycopene from tomatoes is more easily absorbed   inside your body once they have been cooked. How does a scientist usually test a theory?

Choices:
A. By practising it in daily life.
B. By doing scientific research.
C. By discussing it with other scientists.
D. By looking into many scientific reports.

Fifty-three years ago Barbie Millicent Roberts first appeared in the world of toys. Since then, Barbie doll, as everyone called her, has become the most successful toy doll in history.  Her parent, the Mattel Company, said that 90% of all American girls between 3 and 10 have at least one Barbie at home. However, Barbie is facing some trouble at present . There are many similar dolls on the market in competition with her. Another doll named Bratz, for example, came to life thirteen years ago. She looks more like today's pop stars with heavy makeup  and miniskirts. And her company offers more kinds of clothes too. It seems that Barbie has lost her magic among older girls. 'For younger girls, playing with a Barbie is much fun. But when you get older, you want something smarter and more modern,' says Vera Shepherd, a shop assistant in a New York toy store. It is good news that on the international market, Barbie is still No. 1. Although Mattel is selling fewer barbie in the United States these years, sales in other countries are still going up.  In January 2009, Mattel opened its first Barbie store in Shanghai, where girls can shop, eat, drink or even become _ for their own Barbies. Mattel is planning big celebrations for Barbie's 53rd birthday. She has called Fashion designers from all over the world to make new dresses for Barbie. How long will Barbie stay popular in the world of toy dolls? It is hard to say, but 53 is surely not the age to retire . Barbie's trouble is that  _  .

Prompt:
Archery   is one of the oldest sports that are still beingpracticed today. The bow and arrow dates as far back as the Old StoneAge, and is the most widely used weapon in human history. While there is recorded evidence of archery competitions taking place in China more than 3,000 years ago, the modern sport of archery most likely originated in England during the 14th century. Then the sport began to develop fast and there were a few different styles of shooting, some of which developed into what we see today in the sport of archery. There was clout shooting, in which arrows were held high into the air with the purpose of hitting a target which was laid flat, not vertical. The aim was to land the arrow as close to the target as possible. This variety of shooting is still practiced today, often with traditional bows. "Roving marks", another style, saw players shooting at a target, only to shoot at a new target from the location of the previous target. It is said that this is the oldest form of competitive archery, and was practiced by Henry VIII. Finally, there was butt   shooting, in which butts held targets, which the players would shoot at. This is the ancestor of modern-day Olympic target shooting. Archery was a part of the second Olympic Games, which was held in 1900. It was dropped after 1920, however, because rules varied too much between nations. Archery was brought back into the Olympics in 1972. This was after enough nations had formed archery governing bodies affiliated with the Federation Internationale de Tir l'Arc, which was founded in Paris in 1931, to standardize rules for international competitions. From its early history to modern times, archery has always been a competitive sport. Surely, many years from now archery will continue to be a popular sport reaching across age gaps and national borders, uniting archery lovers from all over the world. What would be the best title for the text?

Choices:
A. A brief history of competitive archery.
B. Archery at the Olympic Games.
C. Different styles of archery.
D. How to do competitive archery.

Prompt:
"Does my smile look big in this?" Future fitting-room mirrors in clothing stores could subtly adjust your reflection to make you look - and hence feel - happier, encouraging you to like what you see. That's the idea behind the Emotion Evoking System developed by Shigeo Yoshida and colleagues at the University of Tokyo in Japan. The system can manipulate, or in other word, control your emotions and personal preferences by presenting you with an image of your own smiling or frowning face. The principle that physiological changes can drive emotional ones - that laughter comes before happiness, rather than the other way around - is a well-established idea. The researchers wanted to see if this idea could be used to build a computer system that manipulates how you feel. The system works by presenting the user with a web-camera image of his or her face - as if they were looking in a mirror. The image is then subtly altered with software, turning the corners of the mouth up or down and changing the area around the eyes, so that the person appears to smile or frown  . Without telling them the aim of the study, the team recruited   21 volunteers and asked them to sit in front of the screen while performing an unrelated task. When the task was complete the participants rated how they felt. When the faces on screen appeared to smile, people reported that they felt happier. On the other hand, when the image was given a sad expression, they reported feeling less happy. Yoshida and his colleagues tested whether manipulating the volunteers' emotional state would influence their preferences. Each person was given a scarf to wear and again presented with the altered webcam image. The volunteers that saw themselves smiling while wearing the scarf were more likely to report that they liked it, and those that saw themselves not smiling were less likely. The system could be used to manipulate consumers' impressions of products, say the researchers. For example, mirrors in clothing-store fitting rooms could be replaced with screens showing altered reflections. They also suggest people may be more likely to find clothes attractive if they see themselves looking happy while trying them on. "It's certainly an interesting area," says Chris Creed at the University of Birmingham, UK. But he notes that using such technology in a shop would be harder than in the lab, because people will use a wide range of expressions. "Attempting to make slight differences to these and ensuring that the reflected image looks believable would be much more challenging," he says. Of course, there are also important moral questions surrounding such subtly manipulative technology. "You could argue that if it makes people happy what harm is it doing?" says Creed. "But I can imagine that many people may feel manipulated, uncomfortable and cheated if they found out." What can we learn about the web-camera image in the study?

Choices:
A. It recorded the volunteers' performance in the task.
B. It gave the volunteers a false image.
C. It attempted to make the volunteers feel happier.
D. It beautified the volunteers' appearance in the mirror.

Prompt:
This question refers to the following information.
In Russia there was nothing going on well, and [Souvarine] was in despair over the news he had received. His old companions were all turning to the politicians; the famous Nihilists who made Europe tremble-sons of village priests, of the lower middle class, of tradesmen-could not rise above the idea of national liberation, and seemed to believe that the world would be delivered-when they had killed their despot&…
"Foolery! They'll never get out of it with their foolery."
Then, lowering his voice still more, in a few bitter words he described his old dream of fraternity. He had renounced his rank and his fortune; he had gone among workmen, only in the hope of seeing at last the foundation of a new society of labour in common. All the sous in his pockets had long gone to the urchins of the settlement; he had been as tender as a brother with the colliers, smiling at their suspicion, winning them over by his quiet workmanlike ways and his dislike of chattering. But decidedly the fusion had not taken place.
His voice changed, his eyes grew bright, he fixed them on étienne, directly addressing him:
"Now, do you understand that? These hatworkers at Marseilles who have won the great lottery prize of a hundred thousand francs have gone off at once and invested it, declaring that they are going to live without doing anything! Yes, that is your idea, all of you French workmen; you want to unearth a treasure in order to devour it alone afterwards in some lazy, selfish corner. You may cry out as much as you like against the rich, you haven't got courage enough to give back to the poor the money that luck brings you. You will never be worthy of happiness as long as you own anything, and your hatred of the bourgeois proceeds solely from an angry desire to be bourgeois yourselves in their place."
émile Zola, French writer, Germinal, 1885

I. N/A

Answer: A


Prompt:
This question refers to the following information.
The following excerpt is from a pamphlet.
You will do me the justice to remember, that I have always strenuously supported the Right of every man to his own opinion, however different that opinion might be to mine. He who denies to another this right, makes a slave of himself to his present opinion, because he precludes himself the right of changing it.
The most formidable weapon against errors of every kind is Reason. I have never used any other, and I trust I never shall.
The circumstance that has now taken place in France of the total abolition of the whole national order of priesthood, and of everything appertaining to compulsive systems of religion, and compulsive articles of faith, has not only precipitated my intention, but rendered a work of this kind exceedingly necessary, lest in the general wreck of superstition, of false systems of government, and false theology, we lose sight of morality, of humanity, and of the theology that is true.
I believe in one God, and no more; and I hope for happiness beyond this life.
I believe in the equality of man; and I believe that religious duties consist in doing justice, loving mercy, and endeavoring to make our fellow-creatures happy.
I do not believe in the creed professed by the Jewish church, by the Roman church, by the Greek church, by the Turkish church, by the Protestant church, nor by any church that I know of. My own mind is my own church.
All national institutions of churches, whether Jewish, Christian or Turkish, appear to me no other than human inventions, set up to terrify and enslave mankind, and monopolize power and profit.
I do not mean by this declaration to condemn those who believe otherwise; they have the same right to their belief as I have to mine.
—Thomas Paine, The Age of Reason, 1794–1795

Answer: C


Prompt:
This question refers to the following information.
"The struggle against neo-colonialism is not aimed at excluding the capital of the developed world from operating in less developed countries. It is aimed at preventing the financial power of the developed countries being used in such a way as to impoverish the less developed.
Non-alignment, as practiced by Ghana and many other countries, is based on co-operation with all States whether they be capitalist, socialist or have a mixed economy. Such a policy, therefore, involves foreign investment from capitalist countries, but it must be invested in accordance with a national plan drawn up by the government of the non-aligned State with its own interests in mind. The issue is not what return the foreign investor receives on his investments…The question is one of power. A State in the grip of neo-colonialism is not master of its own destiny."
Kwame Nkrumah, Neo-Colonialism, 1965
