The world consumes hundreds of billions of single-use plastic bags each year. They are difficult to recycle, wasteful and damage the nature. Environmental activists want to ban plastic bags or—as many communities have done —charge a fee for them. But the plastic bag industry defends their use, saying people reuse plastic bags, and industry officials argue recycling is a matter of personal responsibility and should not be forced.

    City officials say New Yorkers use 5.2 billion plastic bags each year. They are offered free with nearly every supermarket, or convenience store purchase. Many people like them, even if they sometimes feel guilty about using them. But what happens to those bags after they've been used in a huge environmental problem. They are found on beaches. They are caught in trees. They are swallowed by marine life.

    Plastic bags are made of petroleum products and natural gas, and do not biodegrade (分解). And they are difficult to recycle. So New York City spends nearly $ 10 million dollars a year to send 100—thousand tons of plastic bags to landfills out of state.

    In Washington, D.C., a five percent charge on all single-use bags led to about a 60 percent reduction and in Los Angeles County in California , a 10 cent charge on single-use bags led to a 95 percent reduction. With a 10 cent charge on bags, customers are much more likely to stop and think about whether they need a bag or not. And that's really all that these laws are doing.

    Teachers' Day around the world is not celebrated on the same day. In some countries, Teachers' Day is celebrated on working days. However, in other countries, it is celebrated on holidays.

    Here we are giving you a list of countries that celebrate Teachers' Day on holidays.

China

    The Teachers' Day was proposed(提议) at National Central University in 1931. It was adopted(被采纳) by the central government of Republic of China in 1932. In 1939, the day was set on August 27th, Confucius's birthday. People's Republic of China government called it off in 1951. It was reestablished in 1985, and the day was changed to September 10th. Now more and more people are trying to celebrate the Teachers' Day back to Confucius's birthday.

India

    In India, Teachers' Day is celebrated on September 5th, in honor of Dr Sarvepalli Radhakrishnan, the second President of India. Because his birthday was September 5th. At schools on this day, students in India celebrate this day to show their respect and love to their teachers.

Russia

    In Russia Teachers' Day is on October 5th. Before 1994, this day was set on the first Sunday of September.

USA

    In the United States, Teachers' Day is a holiday on the Tuesday of the first full week of May.

Thailand

    January 16th was adopted as Teachers' Day in the Thailand by a resolution(决议) of the government on November 21, 1956. The first Teachers' Day was held in 1957.

Iran

    In Iran, Teachers' Day is celebrated on May 2nd every year. It is in honor of the famous Iranian professor Ayatollah Morteza Motahhari who died on May 2, 1980.

    Although different countries celebrate Teachers' Day on different days, the activities people take to celebrate it just stay the same.

    I became a magician by accident. When I was nine years old, I learned how to make a coin disappear. I'd read The Lord of the Rings and gone into the adult section of the library to be buried in fantasy literature but young enough to still hold out hope that you might find a book of real, actual magic in the library. The book I found taught basic techniques, and I tried to practice.

    At first the magic wasn't any good. It was just a trick—a bad trick. I spent hours each day running through the secret moves in front of the mirror. I dropped the coin over and over, a thousand times in a day, and after two weeks my mom got a carpet and placed it under the mirror to muffle (消音) the sound of the coin falling again and again.

    One day I made the coin disappear on the playground. We had been playing football and were standing in the field behind the school. A dozen people were watching. I showed the coin to everyone. Then it disappeared. The kids screamed. Everyone went crazy.

    A few years later, I staged an underwater escape in the river that flowed through the middle of the campus of the University of Iowa, where I went to school. I stood on a boat in the middle of the river wearing nothing but biking shorts. The sky was dead and gray, and the water was cold at the surface, and colder in the depths below.

    Technically, I succeeded. I jumped into the water, sank to the bottom, and escaped from the locks and the chains before swimming to the surface. But it didn't feel like a success.

    Foxes and farmers have never got on well. These small dog-like animals have long been accused (控告)of killing farm animals. They are officially considered as harmful and farmers try to keep their numbers down by shooting or poisoning them.

    Farmers can do call on the services of their local hunt to control the fox population. Hunting consists of hunting a fox across the countryside, with a group of specially trained dogs, followed by men and women riding horses. When the dogs eventually catch the fox, they kill it or a hunter shoots it.

    People who take part in hunting think of it as a sport; they wear a special uniform of red coats and white trousers, and follow strict codes of behavior. But owning a horse and hunting regularly is expensive, so most hunters are wealthy.

    It is estimated (估计) that up to 100,000 people watch or take part in fox hunting . But over the last couple of decades the number of people opposed to fox hunting, because they think it is cruel, has risen sharply. Noisy confrontations between hunters and saboteurs have become so common that they are almost as much a part of hunting as the hunting of foxes itself. But this year supporters of fox hunting face a much bigger threat to their sport. A Labour Party Member of the Parliament, Mike Foster, is trying to get Parliament to approve a new law which will make the hunting of wild animals with dogs illegal. If the law is passed, wild animals like foxes will be protected under the ban in Britain.

    Petrol and diesel cars may still dominate our roads, but their days are numbered. A recent university study found that current electric cars could be used for 87 per cent of daily car journeys in the US. That figure could rise to 98 per cent by 2020.

One hurdle to the widespread adoption of electric cars has been ‘range anxiety'— drivers' concerns about running out of juice on a journey. While petrol stations are conveniently located across national road systems, the necessary network of electric charging stations is still being developed. That said, charging points are becoming increasingly common throughout the USA.

    Attitudes towards electric vehicles have changed quite considerably over the last few years. Not that long ago, electric cars were met with distrust, and their large price tags drove customers away. Thanks to improvements in battery capacity, recharging times, performance and price, the current generation of electric cars are starting to persuade critics. Plug-in cars will soon give internal combustion engine models a run for their money.

    As well as advancements on the road, electric vehicles are taking to the seas and skies. Electric boats are among the oldest methods of electric travel, having enjoyed several decades of popularity from the late 19th to the early 20th century before petrol-powered outboard motors took over. Now, the global drive for renewable energy sources is bringing electric boats back. Steps towards electric air travel are also being made, with Airbus and NASA among the organizations developing and testing battery powered planes. The experiments could soon make commercial electric flight a reality.

    Electric vehicles do not produce any emissions. Were the US to act on the study's findings and replace 87 per cent of its cars with electric vehicles, it would reduce the national demand for petrol by 61 per cent. However, because of the production processes and the generation of electricity required to charge these vehicles, they cannot claim to be completely emission-free. That said, as many countries continue to increase their use of renewable energy sources, electric vehicles will become even cleaner.
