At the end of the 16th century, about five to seven million people     1     ( speak) English. Later in the next century, people from England made voyages to conquer other parts of the world and because       2     that, English began to     3     (speak) in many other countries. Today, more people speak English as their first, second or foreign language than ever before.

Native English speakers can understand each other even     4     they don’t speak the same kind of English. Look at this example:

British Betty: Would you like to see my     5    ?

American Amy: Yes, I’d like to come up to your apartment.

At first the English     8    (speak) in England between about AD 450 and 1150 was very different from the English spoken today. It was based more     9    German than the English we speak now.
