Floods are second only to fire as the most common of all natural disasters.They occur almost everywhere in the world,resulting in widespread damage and even death.Consequently,scientists have long tried to perfect their ability to predict floods.So far,the best that scientists can do is to recognize the potential for flooding in certain conditions. There are a number of conditions,from deep snow on the ground to human error,which cause flooding.

    When deep snow melts it creates a large amount of water.Although deep snow alone rarely causes floods,when it occurs together with heavy rain and sudden warmer weather it can lead to serious flooding.If there is a fast snow melt on top of frozen or very wet ground,flooding is more likely to occur than when the ground is not frozen.Frozen ground or ground that is very wet cannot absorb the additional water created by the melting snow.Melting snow also contributes to high water levels in rivers and streams.

    Rivers that are covered in ice can also lead to flooding.When ice begins to melt,the surface of the ice cracks and breaks into large pieces.These pieces of ice move and float down the river,They can form a dam in the river,causing the water behind the dam to rise and flood the land upstream.If the dam breaks suddenly,then the large amount of water held behind the dam can flood the areas downstream too.

    Broken ice dams are not the only dam problems that can cause flooding.When a large human-made dam breaks or fails to hold the water collected behind it,the results can be devastating.Dams contain such huge amounts of water behind them that when sudden breaks occur,the great force of the water is like a great tidal wave.The dam waters can travel tens of kilometres,cover the ground in metres of mud and litter,and drown and crush every thing and creature in their path.

    Although scientists cannot always predict exactly when floods will occur,they do know a great deal about when floods are probably going to occur.Deep snow,ice-covered rivers,and weak dams are all strong conditions for potential flooding.

    Kenya-Giraffe Conservation

    Preserve and protect Kenya's Wildlife

    After some difficult years, Kenya is back in fashion and welcoming travellers with open arms, with one main aim—help save and protect their unique wildlife. It isn't just the elephant under threat, but it's the smaller species that are also suffering, for example, Rothschild Giraffes. Now there are only 670 left in the wild and they need your help to survive.

    How can you help?

    Head out to the Soysambu Conservancy, which is home to more than 450 bird species and over 50 different mammals, including lions, zebra and more than 100 critically endangered Rothschild's Giraffes.

Get stuck into general reserve conservation but primarily focus on the research and protection of their resident Rothschild Giraffes, which is the reserve's main priority.

    Your Daily Tasks

    Work will be a combination of observational research and hands on work—five days a week.

    Minimum number of weeks is 2. This project is perfect for anyone with a passion for nature, wildlife, and the great outdoors.

    No previous conservation experience required.

    Where will you live?

    You will stay in the houses right in the middle of the reserve with other volunteers.

    The weekends will be free time, so you can explore further up the Rift Valley, Lake El-menteita itself and beyond.

    First published in 2001, the book Life of Pi written by Canadian author Yann Martel won the Man Booker Prize and an Asian American Prize for Literature. It is the story of a young boy named Pi who spends 227 days at sea with a small group of animals after disaster strikes their ship and is an account of his journey of survival and hardship.

    Piscine “Pi” Molitor Patel, on whom Life of Pi is based, is a young boy living in Pondicherry, India, where his father owns a zoo. The story starts when Patel's family decide to move to Canada, along with their zoo animals for their new home.

    However, because of the bad weather, the ship sinks. Pi along with an orangutan (猩猩), an injured zebra, a hyena (鬣狗) and a Bengal tiger named Richard Parker are the only survivors who take shelter in a small lifeboat. Both the injured zebra and the orangutan are soon killed and eaten by the hyena. The tiger in turn kills and eats the hyena, leaving just the two of them alone on the boat now.

    In an effort to avoid being eaten by Richard Parker, Pi acts himself as the head of the group and remains safe from harm. Since he does not want the tiger to die for fear of going mad by being alone on the boat, he fishes and feeds the two of them in order to stay alive.

    The life of Pi then enters its third stage when their lifeboat washes up on the shores of Mexico and the tiger escapes into a nearby forest leaving Pi alone. After the Mexicans refuse to believe Pi's story, he changes his tale by replacing the animals with his mother, a cook and a sailor and asks the Mexicans which one they prefer. They prefer hearing the first story though they do not believe a word of it.

    In my view, Life of Pi is a must read book for all those who love reading.

    The poverty line is the minimum income that people need for an acceptable standard of living. People with incomes below the poverty line are considered poor. Economists study the causes of poverty in order to find solutions to the problem.

    As the general standard of living in the country rises, the poverty line does, too. Therefore, even with today's relatively high standard of living, about 10 percent of the people in the United States are below the poverty line. However, if these people had stable jobs, they could have an acceptable standard of living. Economists suggest several reasons why poor people do not have jobs.

    For one thing, more than half of the poor people in the United States are not qualified to work. Over 40 percent of the poor people are children. By law, children less than 16 years old cannot work in many industries. A large number of poor people are old. Many companies do not hire people over 65 years old, the normal retirement age.

    Some poor adults do not look for jobs for a variety of personal reasons: they are sick, they do not have any motivation, they have family problems, or they do not believe that they can find a job.

    Other poor people look for a job, but cannot find one. Many poor adults never went to high school. Therefore, when they look for jobs, they have few skills that they can offer.

    At the present time, the government thinks it can reduce poverty in the country in the following ways:

    First, if the national economy grows, businesses and industries hire more workers. Some of the poor who are qualified to look for jobs may find employment. Then they will no longer below the poverty line.

    Second, if society invests in the poor，the poor will become more productive.

    If the government spends money on social programs, education and training for poor people, the poor will have the skills to offer. Then it is more probable that they can find jobs.

    Finally, if the government distributes society's income differently, it raises some poor people above the poverty line. The government collects taxes from the non-poor and gives money to the poor. These payments to the poor are called welfare.

    Some economists are looking for better solutions to the poverty problem. However, at the present time, many people depend on welfare for a minimally acceptable standard of living.

Foreign visitors to the UK might be disappointed when they learn that not everyone there speaks like Harry Potter and his friends. Usually, there's an assumption by many non-Brits that everyone in Britain speaks with what's known as a Received Pronunciation (RP, 标准发音) accent, also called "the Queen's English". However, while many people do talk this way, most Britons speak in their own regional accents.

    Scouse, Glaswegian and Black Country – from Liverpool, Glasgow and the West Midlands – are just three of the countless non-RP accents that British people speak with. There are even differences in accents between towns or cities just 30 kilometers apart. What is even more disappointing is that not speaking in a RP accent may mean a British person is judged and even treated differently in their everyday life.

    In a 2015 study by The University of South Wales, videos of people reading a passage in three different UK accents were shown to a second group of people. The group then rated how intelligent they thought the readers sounded. The lowest-rated accent was Brummie, native to people from Birmingham, a city whose accent is considered working class.

    However, there is no need to be disappointed though you are not speaking in an RP accent. In fact, doing the opposite may even give you strength.

Kong Seong-jae, 25, is an internet celebrity from Seoul. After studying in the UK, he picked up several regional accents. He's now famous for his online videos, where he shows off the various accents he's learned. "British people usually get really excited when I use some of their local dialect words, and they become much friendlier. I think it makes a bit of bond between local people and foreigners to speak in their local accent," he said.

    So if you're working on perfecting your British accent, try to speak like someone from Liverpool, Glasgow or Birmingham. You may not sound like Harry Potter, but you are likely to make more friends.

    There was an earthquake this morning. I was working in front of my computer when it hit the city. The quake started with a sudden loud noise. I thought that something heavy in a neighbor's house probably had fallen. However, the walls and the floor began to shake. I finally realized it was an earthquake.

    My son Zac, a sixteen­year­old boy, was sleeping with his door locked. Being sixteen, he can sleep through any kind of noise. "Zac!" I shouted. "Are you OK?" But nobody replied. I was a little worried. I couldn't imagine that someone was able to get such a deep sleep. The house was dancing. There were waves in the swimming pool. I was afraid the house would come down. "Zac!" I yelled, knocking on his door with an open palm (手掌). "Zac! Wake up! It's an earthquake! We need to get out!"

    My son finally emerged in his underpants. We looked around the room. I knew that we should hide under a table to stop things from falling on us and stay away from glass. Unfortunately, none of our furniture was designed for hiding under. "Should we go into the garden?" Zac asked. "No, trees could fall on us!" I said. Actually, Zac had done earthquake drills (训练) at school. He must have been told to hide under a desk and cover his head. But we had nothing to cover our heads in the house.

    Luckily, before we took any action, the windows stopped moving and the pool calmed down. Everything went back to normal soon. But both my son and I knew what we should do, because we knew if there had been a really big earthquake this morning, we couldn't have escaped from it.
