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 had written in it an account of what we did each day，we should be able to give an answer to the question.
It is the same in history. Many things have been forgotten because we do not have any written account of them. Sometimes men did keep a record of the most important happenings in their country，but often it was destroyed by fire or in a war．Sometimes there was never any written record at all because the people of that time and place did not know how to write．For example，we know a good deal about the people who lived in China 4，000 years ago, because they could write and leave written records for those who lived after them．But we know almost nothing about the people who lived even 200 years ago in central Africa, because they had not learned to write．
Sometimes,of course，even if the people cannot write，they may know something of the past．They have heard about it from older 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 for many generations .For most people are proud to tell what their fathers did in the past．This we may call ’remembered history’．Some of it has now been written down. It is not so exact or so valuable to us as written history is，because words are much more easily changed when used again and again in speech than when copied in writing．But where there are no written records，such spoken stories are often very helpful．
【小题1】．We know very little about the central Africa 200 years ago because A．there was nothing worth being written down at that timeB．the people there ignored the importance of keeping a recordC．the written records were perhaps destroyed by a fireD．the people there did not know how to write【小题2】．“Remembered history”refers to ．A．history based on a person’s imaginationB．stories of important happenings passed down from mouth to mouthC．songs and dances about the most important eventsD．both B and C【小题3】．“Remembered history”is regarded as valuable only when .A．it is written downB．no written account is availableC．it proves to be timeD．people are interested in it【小题4】 .The passage suggests that we could have learned much more about our past than we do now if the ancient people had A．kept a written record of every past eventB．not burnt their written records in warsC．told exact stories of the most important happeningsD．made more songs and dancesD

(答案→)D 解析：【小题1】D 细节题。根据第二段最后一句But we know almost nothing about the people who lived even 200 years ago in central Africa, because they had not learned to write．说明非洲人没有学会写字是没有关于他们的记录的原因。故Ｄ正确。【小题2】.D 细节题。根据第三段2,3，4行They have heard about it from older 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 for many generations .For most people are proud to tell what their fathers did in the past．This we may call ’remembered history’说明人们从祖先那里听来的内容和关于重大事件的歌曲和舞蹈等记录就是所谓的’remembered history，故D正确。【小题3】B 细节题。根据文章最后一句But where there are no written records，such spoken stories are often very helpful．说明在没有书面记录的时候，Remembered history才被认为是重要的。故B正确。【小题4】.A 推理题。根据文章第二段第一行It is the same in history. Many things have been forgotten because we do not have any written account of them.说明历史上的很多事情都被遗忘就是因为没有书面的记录，如果有了文字等书面的记录，那么很多历史及会被保留。故A正确。

这个答案应该是对的
