Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions. 
      In the early 1800s, less than 3% of the world's population lived in cities; today, more than half of the global population is urban and by 2050, the proportion will rise to three quarters. There are thousands of small and medium-sized cities along with more than 30 megacities and sprawling, networked metropolitan areas with 15 million residents or more. Yet despite these massive transformations in how people live and interact, our international affairs are still largely dictated by national states, not cities.
       Cities are beginning to flex their muscles on the international stage. They are already displacing nation states as the central nodes of the global economy, generating close to 80% of global GDP. Cities like New York and Tokyo are bigger in GDP terms than many G-20 countries. Metropolitan regions and special economic zones are linking global cities through transnational supply chains. A growing number of mega-regions, such as those linking cities in Mexico and the U.S., transcend borders. In the process, cities are collectively forging common regional plans, trading partnerships, and infrastructure corridors.
      The spectacular rise of cities did not happen by accident. Cities channel creativity, connect human capital, and when well governed, they drive growth. That many cities and their residents are rolling up their sleeves and getting things done - where nations have failed - are grounds for optimism. In the future, we hope that it is our proximate, accountable, and empowered city leaders who will define our fates. 

The word "they” in paragraph 4 refers to ____.

There are a number of natural disasters that can strike across the globe. Two that are frequently linked to one another are earthquakes and tsunamis. Both of them can cause a great amount of devastation when they hit. However, tsunamis are the direct result of earthquakes and cannot happen without them.
The Earth has three main parts. They are the crust, the mantle, and the core. The crust is the outer layer of the Earth. It is not a single piece of land. Instead, it is comprised of a number of plates.
There are a few enormous plates and many smaller ones. These plates essentially rest upon the mantle, which is fluid. As a result, the plates are in constant – yet slow – motion. The plates may move away from or toward other plates. In some cases, they collide violently with the plates adjoining them. The movement of the plates causes tension in the rock. Over a long time, this tension may build up. When it is released, an earthquake happens.Tens of thousands of earthquakes happen every year. The vast majority are so small that only scientific instruments can perceive them. Others are powerful enough that people can feel them, yet they cause little harm or damage. More powerful earthquakes, however, can cause buildings, bridges, and other structures to collapse. They may additionally injure and skill thousands of people and might even cause the land to change it appearance.
Since most of the Earth’s surface is water, numerous earthquakes happen beneath the planet’s oceans. Underwater earthquakes cause the seafloor to move. This results in the displacement of water in the ocean. When this occurs, a tsunami may form. This is a wave that forms on the surface and moves in all directions from the place where the earthquake happened. A tsunami moves extremely quickly and can travel thousnads of kilometres. As it approaches land, the water near the coast gets sucked out to sea. This causes the tsunamis to increase in height.
Minutes later, the tsunami arrives. A large tsunami – one more than ten meters in height – can travel far inland. As it does that, it can flood the land, destroy human settlements, and kill large numbers of people

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
Charles Lindbergh was born in Detroit, Michigan, in 1902 but was raised on a farm in Minnesota, where his father was elected to the U.S. Congress in 1907. From then on, he spent his boyhood alternately in Washington, D.C. Detroit, and Little Falls, Minnesota. Because Lindbergh exhibited exceptional mechanical talent, in 1921 he was admitted to the University of Wisconsing to study engineering. However, the young man was seeking more challenging endeavors, and two years later he became a stunt pilot who performed feats at county fairs and public assemblies. This unusual and dangerous undertaking paid off handsomely in the sense that it allowed him to gain a diverse and well–rounded experience in aeronautics. He particularly delighted in what he called “wing–walking” and parachute jumping.
After a year of training as a military cadet, Lindbergh completed his program at the Brooks and Kelly airfields at the top of his class and earned the rank of captain.
Robertson Aircraft Corporation of St. Louis, Missouri, offered him employment as a mail pilot to run the routes between St. Louis and Chicago, and Lindbergh retained his position with the company until 1927. During this period, he set out to win the Raymond B. Orteig prize of $25,000 to be awarded to the first pilot to fly nonstop from New York to Paris. This ambition would irreversibly change his life and accord him a prominent place in the history of aviation.
Embarking on the greatest adventure of his time, Lindbergh left Roosevelt Field at 7:52 A.M. on May 20, 1927, and landed at Le Bourget Field at 5:24 P.M. the next day. Fearing that he would be unknown when he arrived, Lindbergh carried letters of introduction to dignitaries in Paris, but when his plane came to a stop, he was overwhelmed by tremendous welcoming crowds. He was decorated in France, Great Britain, and Belgium, and President Coolidge sent a specially designated cruiser, the Memphis, to bring him back, His accomplishments in aeronautics brought him more medals and awards than had ever been received by any other person in private life.

Today we take electricity for granted and perhaps we do not realize just how useful this discovery has been. Steam was the first invention that replaced wind power. It was used to drive engines and was passed through pipes and radiators to warm rooms. Petrol mixed with air was the next invention that provided power. Exploded in a cylinder, it drove a motor engine. Beyond these simple and direct uses, those forms have not much adaptability. On the other hand, we make use of electricity in thousands of ways. From the powerful voltages that drive our electric trains to the tiny current needed to work a simple calculator, and from the huge electric magnet in steel works that can lift 10 tons to the tiny electric magnet in a doorbell, all are powered by electricity. An electric current can be made with equal ease to heat a huge mass of molten metal in a furnace or to boil a jug for a cup of coffee. Other than atomic energy, which has not as yet been harnessed to the full, electricity is the greatest power in the world. It is flexible, and so adaptable for any task for which it is wanted. It travels so easily and with incredible speed along wires or conductors that it can be supplied instantly over vast distances. To generate electricity, huge turbines or generators must be turned. In Australia they use coal or water to drive this machinery. When dams are built, falling water is used to drive the turbines without polluting the atmosphere with smoke from coal. Atomic power is used in several countries but there is always the fear of an accident. A tragedy once occurred at Chernobyl, in Ukraine, at an atomic power plant used to make electricity. The reactor leaked, which caused many deaths through radiation. Now scientists are examining new ways of creating electricity without harmful effects to the environment. They may harness the tides as they flow in and out of bays. Most importantly, they hope to trap sunlight more efficiently. We do use solar heaters for swimming pools but as yet improvement in the capacity of the solar cells to create more current is necessary. When this happens, electric cars will be viable and the world will rid itself of the toxic gases given off by trucks and cars that burn fossil fuels.

Called the ‘Red Planet,’ Mars is roughly half the size of Earth, and one of our closest neighboring planets. Though Mars is the most Earth-like of any other planet, the two are still worlds apart. Living on Mars has been the stuff of science fiction for decades. However, can humans really live on Mars? Will it ever be possible or safe? NASA (the National Aeronautics and Space Administration) hopes to find out. NASA researchers on Earth are conducting several experiments together with the International Space Station (ISS) to study the health and safety issues that may tell us if life on Mars is possible.
Food and oxygen would be the main necessities for travelers living extended periods on Mars. The need to grow plants, which provide both food and oxygen, would be a key. But the decreased gravity and low atmospheric pressure environment of the planet will stress the plants and make them hard to grow. However, space station crews are growing plants in controlled environments in two of the station’s greenhouses. They take care of the plants, photograph them, and collect samples to be sent back to Earth. Researchers then use the data to develop new techniques that will make it possible to grow plants successfully in space. 
Another concern for space travelers is the health hazards posed by the effect of space radiation on humans. A spacecraft traveling to Mars would be exposed to large amounts of radiation. Since human exposure to such intense radiation would mean certain death, the spacecraft used for such travel would have to protect the humans on the inside of the craft from exposure. Researchers are using special machines inside the crew areas of the International Space Station to carefully watch radiation levels. NASA scientists, who have maintained radiation data since the beginning of human space flight, continue to learn about the dangers it poses. Researchers use the station to test materials that could be used in making a spacecraft that could successfully travel to Mars.
Will it ever be safe for humans to live on Mars? It is still too early to say. But thanks to the dedicated researchers of NASA and the results of ISS experiments, we are getting closer to knowing every day.

The world needs to do more to prepare for the impact of a rapidly ageing population, the UN has warned - particularly in developing countries. Within 10 years the number of people aged over 60 will pass one billion, a report by the UN Population Fund said. The demographic shift will present huge challenges to countries’ welfare, pension and healthcare systems. The UN agency also said more had to be done to tackle "abuse, neglect and violence against older persons".
The number of older people worldwide is growing faster than any other age group. The report, Ageing in the let Century: A Celebration and a Challenge, estimates that one in nine people around the world are older than 60. The elderly population is expected to swell by 200 million in the next decade to surpass one billion, and reach two billion by 2050. This rising proportion of older people is a consequence of success - improved nutrition, sanitation, healthcare, education and economic well-being are contributing factors, the report says.
But the UN and a charity that also contributed to the report, Help Age International, say the ageing population is being widely mismanaged. "In many developing countries with large populations of young people, the challenge is that governments have not put policies and practices in place to support their current older populations or made enough preparations for 2050," the agencies said in a joint statement.

Mark Zuckerberg was born in 1984, in New York, into a prosperous, professional family. He developed an interest in computers at an early age and when he was twelve, he created a messaging program which he named "Zucknet". His dentist father used it in his surgery so that his receptionist could inform him of the arrival of a patient without yelling across the room. Together with his  friends, Mark spent much of his spare time as a boy designing and making computer games just for fun.
In 2002, Mark enrolled at Harvard University. By his second year at the institution, he had acquired a reputation on the campus as a developer of software. It was at that time he invented "Facemash" which compared pictures of female students and allowed users to vote on which one   was the most attractive. The program became very popular on campus, but was later shut down by the university authorities who deemed it 'inappropriate'.
Based on the buzz of "Facemash", three of Mark's fellow students, Divya  Narendra, and  twins, Cameron and Tyler Winklevoss, asked him to work with them on an idea for a social networking site called "Harvard Connection". This site was designed to use information from Harvard's student networks to create a dating site for the university's elite. Mark was initially enthusiastic about the complex project but boredom soon set in
and he backed out of it to work on his own social networking site. He created a  site that allowed  users to produce their own profiles, upload photos, and communicate with other people beyond the confines of the university. He called the site "Facebook" and he operated from one small college room until June 2004 when he finally abandoned his studies to  devote himself fully to Facebook and  moved the company to California. By the end of 2004, Facebook had one million users and Mark was climbing high.

Volunteering has been acknowledged as part of the wider health policy, with the NHS five-year plan identifying a need to encourage community volunteering. It also has an important role to play in tackling social exclusion, through projects such as lunch clubs for older people, assisted gardening schemes, or young play leaders.
Volunteering can help to provide people with ways out of poverty, by giving them new skills, confidence and aid social integration. This is of particular value to those who are most excluded from the labour market, such as recent migrants or people with disabilities. But while the benefits of volunteering are clear, there is worrying evidence that the people who could benefit most from giving their time are precisely those least likely to be involved.
There are many reasons for people not to volunteer. For older people, the barriers can include poor health, poverty, lack of skills, poor transport links, or having caring responsibilities, such as looking after grandchildren. Younger people can be deterred by feeling they don’t have the time to volunteer, or not knowing anyone else who volunteers. Many of them also think volunteering is just for older people with time on their hands. Volunteering has an image problem – particularly with men and younger people.
More should be done to promote the value of volunteering to the particular needs of different groups. There is evidence on why people choose to volunteer, and we need to make better use of that information. For instance, a recent survey showed that 95% of young people, aged 13-24, hoped to develop new skills through volunteering, compared to just 32% of volunteers aged over 55. Almost three quarters of young people were keen to gain qualifications through volunteering compared to just 13% of those over 55. Over three quarters of disabled volunteers were keen to develop new skills and nearly two thirds hoped to improve their health and wellbeing through volunteering.

In most families, conflict is more likely to be about Clothing, music, and leisure time than about more serious matters such as religion and core values. Family conflict is rarely about such major issues as adolescents' drug use and delinquency. Nevertheless, it has been estimated that in about 5 million American families (roughly 20 percent), parents and adolescents engage in intense, prolonged, unhealthy conflict. In its most serious form, this highly stressful environment is associated with a number of negative outcomes, including juvenile delinquency, moving away from home, increased school dropout rates, unplanned pregnancy, membership in religious cults, and drug abuse (Steinberg & Morris, 2001).
Many of the changes that define adolescence can lead to conflict in parent- adolescent relationships. Adolescents gain an increased capacity for logical reasoning, which leads them to demand reasons for things they previously accepted without question, and the chance to argue the other side (Maccoby, 1984). Their growing critical-thinking skills make them less likely to conform to parents' wishes the way they did in childhood. Their increasing cognitive sophistication and sense of idealism may compel them to point out logical flaws and inconsistencies in parents' positions and actions. Adolescents no longer accept their parents as unquestioned authorities. They recognize that other opinions also have merit and they are learning how to form and state their own opinions. Adolescents also tend toward ego- centrism, and may, as a result, be ultra-sensitive to a parent's casual remark. The dramatic changes of puberty and adolescence may make it difficult for parents to rely on their children's preadolescent behavior to predict future behavior. For example, adolescent children who were compliant in the past may become less willing to cooperate without what they feel is a satisfactory explanation.

The first thing to do when you have a trip abroad is to check that your passport is valid. Holders of out–of–date passports are not allowed to travel overseas. Then you can prepare for your trip. If you don't know the language, you can have all kinds of problems communicating with local people. Buying a pocket dictionary can make a difference. You'll be able to order food, buy things in shops and ask for directions. It's worth getting one. Also there's nothing worse than arriving at your destination to find there are no hotels available. The obvious way to avoid this is to book in advance. This can save you money too. Another frustrating thing that can happen is to go somewhere and not know about important sightseeing places. Get a guide book before you leave and make the most of your trip. It's a must.
Then, when you are ready to pack your clothes, make sure they are the right kind. It's no good packing sweaters and coats for a hot country or T–shirts and shorts for a cold one. Check the local climate before you leave.
Also, be careful how much you pack in your bags. It's easy to take too many clothes and then not have enough space for souvenirs. But make sure you pack essentials. What about money? Well, it's a good idea to take some local currency with you but not too much. There are conveniently located cash machines (ATMs) in most big cities, and it's usually cheaper to use them than change your cash in banks. Then you'll have more money to spend. When you are at your destination, other travellers often have great information they are happy to share. Find out what they have to say. It could enhance your travelling experience.

   Different cultures follow their own special customs when a child's baby teeth fall out. In Korea, for example, they have the custom of throwing lost teeth up on the roof of a house. According to tradition, a magpie will come and take the tooth. Later, the magpie will return with a new tooth for the child. In other Asian countries, such as Japan and Vietnam, children follow a similar tradition of throwing their lost teeth onto the roofs of houses.

   Birds aren't the only animals thought to take lost teeth. In Mexico and Spain, tradition says a mouse takes a lost tooth and leaves some money. However, in Mongolia, dogs are responsible for taking teeth away. Dogs are highly respected in Mongolian culture and are considered guardian angels of the people. Tradition says that the new tooth will grow good and strong if the baby tooth is fed to a guardian angel. Accordingly, parents in Mongolia will put their child's lost tooth in a piece of meat and feed it to a dog.

   The idea of giving lost teeth to an angel or fairy is also a tradition in the West. Many children in Western countries count on the Tooth Fairy to leave money or presents in exchange for a tooth. The exact origins of the Tooth Fairy are a mystery, although the story probably began in England or Ireland centuries ago. According to tradition, a child puts a lost tooth under his or her pillow before going to bed. In the wee hours, while the child is sleeping, the Tooth Fairy takes the tooth and leaves something else under the pillow. In France, the Tooth Fairy leaves a small gift. In the United States, however, the Tooth Fairy usually leaves money. These days, the rate is $1 to $5 per tooth, adding up to a lot of money from the Tooth Fairy!

The legal limit for driving after drinking alcohol is 80 milligrams of alcohol in 100 milliliters of blood, when tested. But there is no sure way of telling how much you can drink before you reach this limit. It varies with each person depending on your weight, your sex, if you’ve just eaten and what sort of drinks you’ve had. Some people might reach their limit after only about three standard drinks.
In fact, your driving ability can be affected by just one or two drinks. Even if you’re below the legal limit, you could still be taken to court if a police officer thinks your driving has been affected by alcohol.
It takes about an hour for the body to get rid of the alcohol in one standard drink. So, if you have a heavy drinking session in the evening you might find that your driving ability is still affected the next morning, or you could even find that you’re still over the legal limit. In addition, if you’ve had a few drinks at lunchtime, another one or two drinks in the early evening may well put you over the legal limit.
In a test with professional drivers, the more alcoholic drinks they had had the more certain they were that they could drive a test course through a set of moveable posts … and the less able they were to do it!

So the only way to be sure you’re safe is not to drink at all.

Alcohol is a major cause of road traffic accidents. One in three of the drivers killed in road accidents have levels of alcohol which are over the legal limit, and road accidents after drinking are the biggest cause of death among young men. More half of the people stopped by the police to take a breathalyzer test have a blood alcohol concentrate of more than twice the legal limit.
It is important to remember that driving after you’ve been drinking doesn’t just affect you. If you’re involved in an accident it affects a lot of other people as well, not least the person you might kill or injure. 

The amount of alcohol a person can drink before reaching the legal limit is     .
