Article: As a young adult, Noah Webster was a teacher. At this time, the colonies were fighting for independence from Britain. Yet the books that American children used in school all came from Britain. The books were all about British people and British places. Webster wanted books that would mean more to American children. So he wrote three books that used American examples -- a grammar book, a spelling book, and a reader. These books were very popular, and millions of them were sold. Webster was interested in changing the spellings of words. He wanted words to be spelled the way they were pronounced. For example, he thought the word "head" should be spelled "hed", and the word "laugh" should be spelled "laf". People liked Webster's suggestions. However, few words were actually changed. One group of words that were changed were words in which an unpronounced "u" followed an "o". That is why Americans write "color" and "labor", and the British write "colour" and "labour". With the money he made from his books, Webster was able to write. It was the first American English dictionary, published in 1828. Webster's dictionary had over 70000 words and gave the meaning and origin of each. To this day, Webster's work is the example that most dictionaries of American English follow.

Article: Friends play an important role in our lives, and although we can't be more familiar with the fact of friendship, we often don't clearly understand how we make friends, especially with Americans. Here are some pieces of advice on making friends with Americans: 1. Visiting places Americans enjoy: parties, churches, restaurants, parks and sports clubs. 2. Be willing to take the first step. Don't wait for them to get close to you. Americans in China may not know you speak English. They may be uncomfortable if they can't speak your language. 3. Use small talks to open the conversation. Ask them where they're from, why they come to China, etc. . Remember: Be careful not to ask personal questions about age, salary and so on. 4. Show an interest in their culture, their country or their job. Americans like to talk about themselves! 5. Invite them to join you for dinner or just for coffee or tea. Try to set a specific time. Americans sometimes make general invitations like "Let's go out for dinner sometime. "Often this is just a way to be friendly. It is not always a real invitation. 6. Don't expect too much at first. Maybe they're being friendly. But maybe they want to be your good friends. It will take time to tell.
