Read the text and say whether the sentences below are true or false.
Nearly 265 million people live in the USA and speak English. Although approximately one out of eight people in the US speaks a language other than English at home, there are more native speakers of English there than in any other country.
American English is very flexible and has absorbed many words from the languages of immigrants. Words like liaison and rendezvous (from French), and rodeo and tornado (from Spanish) came into the language because France and Spain once controlled parts of North America. Dutch and German settlers gave words such as waffle and cookies, and hamburger and noodles to American English.
The first English speakers to arrive met Native Americans who spoke many different languages. To trade with them, the Europeans learned words from the local languages, and some of these words became part of American English. The Europeans also learned the Native American names for the places they were passing through. Over half the states now have Native American names.
1. English is the native language for all Americans.
2. Tornado is a French word.
3. The word hamburger came from German.
4. Europeans learned local words to trade with Native Americans.
5. You can’t see many Indian names of the places on the modern map of the USA.
