Speaking English is not only about using proper grammar, but also about understanding the culture. Here is some important advice to remember when speaking English in the United States.

◆Americans have difficulties understanding foreign accents. Many Americans are not used to foreign accents. This requires patience from both of you.

◆Talk about places: Americans love to talk about places. When speaking to a stranger, ask them where they come from and then say something about that place. For example: “Oh, I have a friend who worked in Los Angeles. He says it’s a beautiful place to live in.” Most Americans will then willingly talk about their experiences of living in or visiting that city or place.

◆Talk about work: It is common for Americans to ask “What do you do?” It’s not considered impolite as in some countries and is a popular topic of discussion between strangers.

◆Talk about sports: Americans love sports! However, they love American sports. When speaking about football, most Americans understand “American football”, not soccer.

◆Be careful when expressing ideas about race, religion or other sensitive(敏感的)topics:The United States is a society with different cultures. Americans are very sensitive to other cultures and ideas.
