| When the idea of going to Beirut (贝鲁特) first came to my mind in 2001, I thought something was going wrong with me. I had always thought Beirut was a war-torn (战争创伤的) place with rude and hungry people running all over. But I was wrong. The airport in Beirut was just like any airport you could find in Canada and the United States. Everything was clean and new. The people there were very helpful and very kind. The streets of Beirut were not what I had expected. I thought it would be a terrible place with broken buildings and things of that kind. Instead I saw a beautiful city with tall buildings and busy streets filled with laughing people who were very friendly and understanding of my foreign ways. I thought that their way of life would be different, their clothes and their food. I was right about one thing --- their food was different but it was amazing. However, they have different kinds of western foods and western restaurants. Their clothing is exactly the same. Their language is beautiful and they live a happy life. English and French are widely spoken. I have visited Beirut four times after that and I plan to go there again. | |||||||||||||||
