    It may be hard to believe, but the American Revolution(革命)—the war that freed the American states from British control—began over a cup of tea. Tea was not the only thing that caused the war, of course, but it played a very big part.

    The British people's love of tea is well-known. When the British won control over mush of North America in the early 1700s, they brought their tea- drinking habits with them. Tea quickly became the continents most popular drink. As tea could not be grown locally, just as in Britain, it was shipped into the country—mostly from India.

In the early 1700s, the Britain government made a special deal with the East India Company, as an English trading company. They agreed that no other company was allowed to bring tea to Britain or any country controlled by Britain, including America. It was a great deal for the East India Company, since it meant that the company could decide whatever price it wanted for its products. And it always decided on a high price!

In North America, the local people did not like having to pay such high prices. Instead of overpaying for tea from the British, they turned to Dutch traders, who secretly brought tea to the country that was just as good—and much less expensive. Although this broke the law, the American people didn't care. They got the same cup of tea at a much lower price.

The East India Company, however, didn't like this at all. By the 1760s, they were losing millions of pounds each year to Dutch traders—a huge amount of money in a time when ￡60 a year was considered a good income. Instead of reducing their prices to compete with the Dutch, the company asked the British government for help and the government agreed.

    In 1767, the British introduced new law that increased the prices of all goods which were brought into America. These laws helped make the East India Company even richer and forced local people to pay much more for everything. The American leaders asked the British government not to do so, but the British refused to listen. These unfair laws increased Americans' anger about British rule and the rest, as they say, is history.

    When I was a teenager growing up in Russia, I wanted to leave school and have my own life. The only way I could do this was to work in the local brick factory in my town, or get married. I was nervous when I told my father I wanted to leave school. I thought he would say, "No! You are going to college." He took me by surprise when he said, “OK. We'll go to the brick factory.”
    Two days later, he took me to the factory. I had a very romantic idea of working in a factory. I had imagined everyone to be friends working together and having fun. I even imagined there would be music and singing. I guess I had watched too many movies as a teenager.
    When we arrived at the factory gate, my father spoke to the guard and one minute later we were inside. My father said, “Take your time. Look around.” I walked around the factory looking at the building, the workers, and listening to the noise. It was horrible. I ran back to my father and said, “I want to go home.”
    He asked me, “What do you think of the factory?”
    "It's terrible," I replied.
    "And marriage is even worse!" he said.
    I went back to school the next day thinking about studying hard so I could get into a good college. I enjoyed studying English so I decided to major in languages at college. Thanks to my father and our trip to the brick factory, I now work at the United Nations and my father is very proud of me. I married a very good man and my life is much better than it would have been working in the factory!
