Biogas: a Solution to Many Problems
In almost all developing countries, the lack of adequate supplies of cheap, convenient and reliable fuel is a major problem. Rural communities depend largely on kerosene , wood and dung for their cooking and lighting needs. But kerosene is now priced out of reach of many people and wood, except in heavily forested areas, is in short supply. The search for firewood occupies a large part of the working day and has resulted in widespread deforestation .
Dung is in constant supply wherever there are farm animals and, when dried, it is convenient to store and use. But burning dung destroys its value as fertilizer , thus depriving the soil of a much needed source of humus and nitrogen .
Rural areas of developing countries are also plagues by a lack of adequate sanitation. Improper waste disposal spreads disease, contaminates water sources and provides breeding ground for disease-carrying insects.
The problem of improving environmental hygiene, conserving resources and finding alternative sources of fuel may be unrelated. Their solutions, however, are not, as many countries experimenting with biogas technology are discovering. Biogas, a mixture of methane and carbon dioxide, is produced by the fermentation of organic matter. The process of anaerobic fermentation is a natural one, occurring whenever living matter decomposes. By containing the matter – and the process – in a digester or biogas plant, the combustible gas can be trapped and used as fuel for household lighting and cooking. The digested slurry that remains can be used on the land as a soil conditioner and fertilizer.
Biogas plants have attracted much interest in recent years and they are in use in several Asian countries: 38,000 are reported in rural area of India, 27,000 in Korea and more than 80,000 in China. In most countries, the value of the gas has been the prime factor leading to their adoption: 70 percent of India’s plants, for instance, were built during the energy and fertilizer crisis of 1975-76 – although their use in that country dates back to 1951. similarly in Thailand and Korea, biogas is being investigated as an alternative to costly charcoal and to save compost materials form being burned.
In Japan and China, reducing pollution from animal wastes has been an important factor. Privies, hen houses and pigpens are built in proximity to the fermentation chamber in China. Examinations of the digested slurry have shown that the total number of parasite eggs was reduced by 93.6 per cent, hookworms by 99 per cent and no schistosome flukes were found.
The greatest benefits from biogas systems, however, are probably to be derived from the manorial value of the slurry, although it is not widely used outside of India and China. Vegetable farmers near Calcutta found that the digested slurry produced bigger and better tasting peas than did other fertilizers and the weight of root vegetables increased by nearly 300 per cent.

The Olympic Games
During the Olympic Games, people from all over the world come together in the peace and friendship. Some of these people complete for medals. Several million people attend the games, and millions of other people watch them on television.
Why do we have the Olympic Games? How did they begin? The first Olympic Games that we have records of were in Greece in 776 B.C. The games lasted one day. The only event in the first thirteen Olympic Games was a race. Men ran the length or the stadium (about 192 meters). Then, longer running races were added. Through the years, a few other kinds of events, like the long jump, were also added. During this time, the games were for men only, and women could not even watch them. In the year 393, a Roman emperor ended the Olympic Game because the quality of the games became very low. The Olympics did not take place again for 1500 years!
In 1984, Pierre de Coubertin of France helped from the International Olympic Committee, and the modern Olympic Games began. In1896, the games were held again in Athens, Greece. The Greeks built a new stadium for the competition. Three hundred and eleven athletes from thirteen countries competed in many events. The winners became national heroes.
After 1896, the games were held every four years during the summer in different cities around the world. In 1900, the Olympics were in Paris, France, and women competed for the first time. In 1908, in London, England, the first gold medals were given to winning athletes. Before that time, the winners received only silver and bronze medals. The Olympic flag was first introduced in 1920 in Antwerp, Belgium. The flag has five rings on it. The rings represent the continents of Africa, Asia, Australia, Europe, and North and South American. Each ring is a different color – blue, yellow, black, green, or red – because the flag of each of the countries that compete in the games has at least one of these colors in it.
The Olympic Winter games began in 1924 in Chamonix, France. Athletes competed in winter events such as skiing, ice skating, and ice hockey. Today, the Winter Games take places every four years. The Summer Games also take place every four years, but not in the same year as the winter events. Both the Summer Games and the Winter Games must have at least fifteen events, and they cannot last more than sixteen days.
Until recently, Olympic competitors could not be professional athletes. All of the athletes in the Olympic Games were amateurs. Today, however, many of the Olympic athletes are professional who play their sports for money during the year. Some people disagree with this idea. They believe that the Olympic game are for amateur athletes, not paid professionals. Other people think that any one can play in the Olympic Games. No matter who the athletes are, millions of people throughout the world enjoy watching the greatest athletic competitions, the Summer Game and the Winter Games of the Olympics.

Mô tả câu hỏi Sea Turtles Feel the Heat
A Sea Turtles are some of the oldest species in the world. The earliest sea turtles appeared over 200 million years ago. Today, however, sea turtle are in trouble. Their populations are getting smaller due to human activities and climate change.
B In Australia, conservationists are studying the effects of climate change on sea turtles. They believe global warming may affect sea turtles in several ways. First, warming temperatures lead to rising sea levels. As sea levels rise, beach areas become flooded. Sea turtles lay their eggs in the beach sand. Flooding can destroy sea turtle nests and the eggs inside them.
C Global warming also raises the temperature of sand around a sea turtle’s nest. The temperature of the nest affects the sex of the turtle’s eggs. Warmer temperatures (above 84 degrees Fahrenheit, or 29 degrees Celsius) produce mostly females. Cooler temperatures produce more males. So, as global temperature rise, more female babies will be born. Scientists predict that in 50 years almost all sea turtle babies in northern Australia will be female.
D To survive these changes, sea turtles will need to adapt . But adapting is difficult because the environmental changes are happening quickly. In addition, sea turtles are more at risk from other dangers, especially ones related to human activities. For example, some populations are getting smaller because of predators brought in by humans. As conservationist Mariana Fuentes says, ‘We can’t be sure if sea turtles will adapt on their own.’ They may need our help to survive.
E One of Fuentes’s projects is at Turtle Camp, a beach in northern Australia. Here, Fuentes helps to protect turtles that are laying eggs. She works with a team of rangers and researchers. Together, they prevent predators such as wild pigs and dogs from eating the turtles’ eggs. Without the rangers’ help, the turtles were losing up to 90% of their eggs. Now there are fewer predators, so the turtles can safely lay their eggs.
Write the letter of the correct paragraph (A-E) from the reading next to its main idea.
...... 1. Seaturtles may need help to survive climate change and other dangers.
...... 2. Fuentes help to protect the areas where sea turtles lay their eggs.
...... 3. Sea turtles are old species, but they are now in trouble.
...... 4. Warmer temperatures affect the sex of sea turtles.
...... 5. Climate change is causing problems for sea turtles.

Text 1 Bad manners at work
Etiquette is the name we give to the rules for being polite in a social group. Business etiquette is important for people who often have to make new contacts and build relationships in their work. Politeness can also help to improve the working environment for people in the same office. Some cultures and situations are formal , which means that we have to follow rules; other cultures and situations are more informal .
Text 2 Office workers “admit being rude”
Most office workers say they are rude or bad-mannered at work. Two out of three workers regularly arrive late for meetings, most ignore emails and three out of four use bad language. In a survey of 1,000 workers, two-thirds say that pressure of work is the reason for bad manners.
Other common examples of bad office etiquette include ignoring colleagues and answering mobile phone calls during meetings. Using mobile phones in meetings is impolite and distracts others, research by the University of Surrey shows. If you respond to call when speaking to somebody, it means that the phone call is more important than the person, the survey said. If you answer a call during a meeting, it could mean that the meeting is not important.
Mr Jacobs, managing director of Office Angels, a recruitment firm say it is easy for people to forget their manners in the working environment, which is often very informal and very busy. Workers can forget proper etiquette such as introducing people at meetings, and this is often bad for working relationships.
Psychologist Dr Colin Gill believes that people are not as polite as they were twenty years ago. He said: ‘Courtesy is no longer something that is so much respected in our society.’ People think it is ‘stuffy to be polite or formal.’
Now some organisations are actually investing money in training their junior managers to be polite. Office Angels is encouraging people to arrive on time for meetings, turn off mobile phones and avoid bad manners at work is such a simple thing to do,’ Mr Jacobs says, ‘ and it can have a dramatic impact on improving your working environment and your relationships with others.’
