第2题
Some say it came from the Indian peoples. When Europeans first came to America they heard hundreds of different Indian languages. Many were will developed.
One tribe especially had a well developed language. This was the Chocktaw tribe. They were farmers and fishermen whole lived in the rich Mississippi valley in what is now the state of Alabama. When problems arose, Chocktaw leaders discussed them with the tribal chief. They sat in a circle and listened to the wisdom of the chief.
He heard the different proposals, often raising and lowering his head in agreement, and saying, "Okeh," meaning "it is so."
The Indian languages have given many words to English. Twenty four of the American States almost half, have Indian names, Okalahoma, the Dakotas, Idaho, Wisconsin, Ohio and Tennessee, to name a few. And the names of many rivers, streams, mountains, cities and towns are Indian.
However, there are many people who dispute the idea that "Okay" came from the In di ans. Some say the President Andrew Jackson first used the word "Okay." Others claim the word was invented by John Jacob Astor, a fur trader of the late 1700s who became one of the world's richest men. Still others say a poor railroad clerk made up this word. His name was Obadiah Kelly and he put his initials(首写字母), O.K. on each package people gave him to ship by train.
So it goes, each story sounds reasonable and official.
But perhaps the most believable explanation is that the word "Okay" was invented by a political organization in the 1800s. Martin Van Buren was running for President. A group of people organized a club to support him. They called their political organization the "Okay Club. The letters "O" and "K" were taken from the name of Van Buren's hometown, the place where he was born, old Kinderhook, New York.
There is one thing about "Okay" that the experts do agree on: that the word is pure American and that it has spread to almost every country on earth.
There is something about the word that appeals to peoples of every language. Yet, here in America it is used mostly in speech, not in serious writing. In recent time, "Okay" has been given an official place in the English language. But it will be a long time before Americans will officially accept two expressions that come from "Okay." There are "Oke" and "Okeydoke".
______different opinions as where the word "Okay" came from are mentioned in the text.
A．Four
B．Five
C．six
D．Three
