If we were asked exactly what we were doing a year ago， we should probably have to say that we could not remember. But if we had kept a book and written in it an account of _1_ each day， we should be able to give an answer _2_ the question.
It is the same in the history. __ have been forgotten because we do not have any written account of them. Sometimes men _4_ a record of the important happenings in _5_ country， _6_ often it was destroyed by fire or in a war. Sometimes there was never any written record at all because the people _7_ did not know how to write. For example， we know _8_ the people who lived in China 4，000 years ago， because they could write and _9_ written records for these who live _10_ them. But we know _11_ nothing about the people who lived even 200 years ago in Central Africa， because they _12_.
Sometimes， of course， even if the people cannot write， they may know something of the past. They have learned about it from _13_ people， and often songs and dances and stories have been made about the most important happenings， and these have been sung and acted and told _14_ many generations (後代)。 Most people are proud to tell _15_ their fathers did in the past. This we may call “remembered history”。 _16_ has now been written down. It is not so exact _17_ so valuable to us _18_ written history is， because words are much more easily _19_ when used again and again in speech than copied in writing. But _20_ no written records， such spoken stories are often very helpful.
