English speakers are always creating new words, and we are often able to know w  1      most words
come from.
     Sometimes, h  2   , no one may really know where a word comes from. Did you ever think about
w  3    hamburgers are called hamburgers, especially when they are not made with ham? About a
hundred years ago, some men went to America f  4    Europe. They came from a big city in Germany
called Hamburg. They did not speak good English, but they ate good food. When some Americans saw
them e  5   round pieces of beef, they asked the Germans what it was. The Germans did not understand
the question and answered, 66We come from Hamburg. " One of these Americans owned a restaurant,
and had an idea.
     He cooked some round pieces of beef like those w  6   the men from Hamburg ate. Then he put
each between two pieces of bread and started selling them. Such bread came to be called "hamburgers".
Today 6'hamburgers" are sold in many countries a  7    the world.
     Whether this story is true or not, it certainly is interesting. Knowing why any word has a certain
meaning is i  8   , too.
