孙悟空师傅扫完金光塔后，师傅累得已是满头大汗，八戒见状，忙端上茶去献殷勤，并关心地问道：师傅，您这是扫了多少地啊，累成这样？悟空应声道；扫了多少地？你算算吧，共六层，我以100平方米为标准，超过的记为正数，不足的记为负数，记录如下：+30，+18，+10，0，-15，-25
八戒看了看，嘟嘟囔囔地说，这怎么算…同学们，你能帮八戒算出来吗？
30+18+10+0-15-25，
=58-40，
=18，
18+100×6=18+600=618平方米．
答：师傅共扫了618平方米地．
| During the past three years, the staff members of the Smithsonian Institution’s Family Folklore Project have interviewed hundreds of persons about their family folklore. To prepare for these interviews we drew upon our academic backgrounds in folklore and American studies, and upon our personal backgrounds as members of families, in addition, we reviewed the major instruction guides in genealogy, oral history, family history, and folklore fieldwork. Although these publications were all helpful in some way, no single book was completely adequate since family folklore combines aspects of all the above disciplines. Over time we have developed guidelines and questions that have proven successful for us; we hope that the following suggestions will be helpful to anyone who wishes to collect the folklore of his or her own family. |
The assumption of this passage is that
A．anyone can successfully interview people about their family folklore without prior training.
B．American history is inherent in the family folklore of Americans.
C．American history and folklore of Americans have no connections.
