[单项选择]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 on it an aceount(记录) 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 people 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 written record at all because the people of that time and place did not know how to write.

The Chinese, for example, are not accustomed to the drinking of milk, and may actually become sick if they are compelled to drink a glassful of the beverage. Americans, on the other hand, thrive on milk, although they have many taboos of their own. Some years ago I gave a dinner party during which I served a delicious hors d’’oeuvre filled with a meat that tasted somewhat like chicken. My guests wondered what the meat was, but I refused to tell them until they had eaten their fill. I then explained that they had just dined on the flesh of freshly killed rattlesnake. The reaction was nausea--and in some cases violent vomiting. If I had served rattlesnake to a Chinese, he would doubtless had requested a second helping, for in China the dish is considered a delicacy. Another interesting case is the young man I met recently in New
