Cell Phones in Africa
Starting time the African continent is home to some of the poorest countries on earth, where people struggle to feed their families on less than $2.00 a day. Nevertheless, Africa is also the world's fastest growing market for cell phones. Cell phones have brought twenty-first century technology to villages where people light their huts with candles and walk hours to find drinking water. Some experts think cell phones will improve life for the 680 million Africans more than any other invention of our time. Why are cell phones spreading so rapidly in Africa?
One reason is simply that other forms of communication are difficult. The roads are terrible in many countries, making travel lengthy and expensive. Regular phones require lines to be laid across Africa's vast - jungles and deserts. Cell phones, however, send their signals from towers, which can easily be constructed by hand, sometimes out of leftover pieces of metal. Furthermore, with the difficult economic situation in many African countries, cell phones can be extremely useful. Many Africans have had to move far from their home villages to look for work. With a cell phone, they can call hregularly and keep in touch or even send money. It is also possible in some countries to make purchases or bank deposits with cell phones. People who run small businesses can use the phones to send in orders or keep in touch with customers. Others can make money selling phone time to those who don't have a cell phone of their own.
Recent studies have shown that where cell phone use has increased in Africa, the economy has been strengthened and the people are better off. In Uganda, for example, a charity group has started a new program with Uganda's largest cell phone company. The program, called villagePhone, helps village women get started as phone owners. The women borrow small amounts of money from banks connected to villagePhone and then use that loan money to buy a phone and some calling minutes. Then they can sell phone time in the village to people without phones. In very little time, these women are usually able to repay the money they have borrowed. A • 0 such woman named Fatima had a small shop in her Ugandan village whe she sold household goods and food to support her four children. In the p Fatima rarely had enough money to buy things to sell in her store and so s made very little money from her business. B • However, she realized there was a need for a telephone in her village, since the closest phone was 6.7 miles (4 km) away. She bought a phone with a loan from villagePhone and ran it off an automobile battery. Since starting her villagePhone business, Fatima's income has grown. What's more, her store is now a center of village life. Fatima's story is like many throughout Uganda. C • And for each woman with a phone, a whole village has access to new services new economic possibilities. A similar program has started in neighboring Rwanda. Soon women there will be using cell phones to raise their income level and improve their lives. D •
Look the gaps [•] in the final paragraph. Where does the following sentence best fit?
"Her villagePhone business is one of about 2.000 such success stories, with more women joining every day"

Humans are bringing about another global-scale change in the atmosphere: the increase in what are called greenhouse gases. Like glass in a greenhouse, these gases admit the Sun's light but tend to reflect back downward the heat that is radiated from the ground below, trapping heat in the Earth's atmosphere. This process is known as the greenhouse effect. Carbon dioxide is the most significant of these gases – there is 25 percent more carbon dioxide in the atmosphere today than there was a century ago, the result of our burning coal and fuels derived from oil. Methane, nitrous oxide, and CFCs are greenhouse gases as well.
Scientists predict that increases in these gases in the atmosphere will make the Earth a warmer place. They expect a global rise in average temperature somewhere between 1.0 and 3.5 degrees Celsius in the next century. Average temperatures have in fact been rising and the years from 1987 to 1997 were the warmest years on record. Some scientists are reluctant to say that global warming has actually begun because climate naturally varies from year to year and decade to decade, and it takes many years of records to be sure of a fundamental change. There is little disagreement, though, that global warming is looming.
Global warming will have different effects in different regions. A warmed world is expected to have more extreme weather, with more rain during wet periods, longer droughts, and more powerful storms. Although the effects of future climate changes are unknown, some predict that exaggerated weather conditions may translate into better agricultural yields in areas such as the western United States, where temperature and rainfall are expected to increase, while dramatic decreases in rainfall may lead to severe droughts and plunging agricultural yields in parts of Africa, for example.
Warmer temperatures are expected to partially melt the polar ice caps, leading to a projected sea level rise of 50 centimeters by the year 2050. A sea level rise of this magnitude would flood coastal cities, force people to abandon low-lying islands, and completely inundate coastal wetlands. Diseases like malaria, which at present are primarily found in the tropics, may become more common in the regions of the globe between the tropics and the polar regions, called the temperate zones. For many of the world's plant species, and for animal species that are not easily able to shift their territories as their habitat grows warmer, climate change may bring extinction.

Most weddings in Japan start with a religious ceremony in which usually only family members attend. Afterwards, a banquet is customarily held to which many people, including friends and colleagues, are invited. To celebrate the happy occasion, guests give the bride and groom goshuugi -gift money in special envelopes. Goshuugi from friends is usually 20,000 yen or 30,000 yen.
A typical Japanese wedding party starts when the bride and groom enter the banquet hall together, and take their seats on a slightly raised platform facing their guests. Invited guests are seated closer to the bride and groom, with family and relatives seated further in back. The bride's and groom's bosses usually give congratulatory speeches then their friends sing in celebration. Other wedding highlights include a candle ceremony where the couple holds a candle while greeting their guests at each table, and the cutting of the wedding cake. Afterwards, the bride and groom thank their parents with a speech, then leave to end the party.
In the past, dishes that supposedly brought good fortune, such as prawns and sea breams, were served in abundance. So much of the food was ordered that guests ended up taking the surplus home. Today, the majority of the weddings serve just enough for everyone. Additionally, before leaving, guests would traditionally receive souvenir gifts called hikidemono.
Many wedding ceremonies take place at wedding halls or hotels. Rough estimates show that it costs about 3 million yen to host a wedding party for 80 guests. During Japan's economic bubble, overseas weddings and flamboyant receptions with special effects, such as smoke machines and having the bride and groom fly in on gondolas, were very popular. But these days, couples choose to tie the knot in various ways, from not having any ceremony to having a modest affair, or still going all out.

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.
The word robot first appeared in a 1921 stage play by Czech writer Karel Capek. In the play, a man makes a machine that can think, which he calls a robot and which ends up killing its owner. In the 1940s, the American science fiction writer Isaac Asimov wrote a series of stories about robots and invented the term robotics, the science of robots. Meanwhile, in the real world, the first robots were developed by an engineer, Joseph F. Engelberger, and an inventor, George C. Devol. Together they started Unimation, a manufacturing company that produced the first real robot in 1961, called the Unimate. Robots of this type were installed at a General Motors automobile plant and proved to be a success. They worked reliably and saved money for General Motors, so other companies were soon acquiring robots as well.
These industrial robots were nothing like the terrifying creatures that can often be seen in science fiction films. In fact, these robots looked and behaved nothing like humans. They were simply pieces of computer-controlled machinery, with metal "arms" or "hands." Since they were made of metal, they could perform certain jobs that were difficult or dangerous for humans, particularly jobs that involve high heat. And since robots were tireless and never got hungry, sleepy, or distracted, they were useful for tasks that would be tiring or boring for humans. Industrial robots have been improved over the years, and today they are used in many factories around the world. Though the use of robots has meant the loss of some jobs, at the same time other jobs have been created in the design, development, and production of the robots.
• Outside of industry, robots have also been developed and put to use by governments and scientists in situations where humans might be in danger. For example, they can be sent in to investigate an unexploded bomb or an accident at a nuclear power plant. B• In space exploration, robots have performed many key tasks where humans could not be present, such as on the surface of Mars. C• In 2004, two robotic Rovers-small six-wheeled computerized cars-were sent to Mars. D•
What can be said about robots?




A.They take away some jobs but offer some in return.
B.Their appearance negatively affects the job market.
C.They put jobs in relation to designers in danger.
D.They develop weapon industry.
