Dear Xiao Ming,

Do you know how to write an English letter? When we write a letter in Chinese, we always put the date at the end of the letter. But it is different in English. We have to put it on the top of the right corner. And above the date, we also write the number of our house and the names of our street, city and country. To begin the letter, we always use words like “Dear sir”, “Dear Mr/Miss/Mrs ...”. At the end of the letter, we usually use words like “Yours”, “Yours ever” or “Truly yours”.

Yours,

Wang Lu

Our world is getting smaller and smaller. We can fly around the world in less than 50 hours. The newest plane can fly at 600 miles an hour. You can have breakfast in Tokyo and supper in Paris.

　 　But hundreds of years ago, it took people a long time to go around the world. Magellan’s(麦哲伦) men were the first to make that trip. They went by ship and it took them more than two years. On September 20th, 1510,he left Spain(西班牙) with five ships and 240 men. He was killed in the Philippines(菲律宾). More than two years later, on December 21st, 1512 , only one of the five ships with just 31 men returned to Spain. Magellan’s trip taught us that the world was round and that people could go around the world.
