中文摘要：

本文从《汉语水平词汇与汉字等级大纲》数据库中的“单音节语素数据库”随机选取一些多义语素作为实验材料，来考察多义语素的家族问题，结果发现：语素的多义性对留学生词汇习得的影响很大。根据研究成果，我们提出“语素教学”要有针对性，尤其是面对“多义语素”，更要根据其自身的不同特征及家族成员的特点来采取相应的教学对策，从而有效地贯彻“语素教学”的构想。

英文摘要：

This paper chooses randomly some polysemous morphemes from The Monosyllabic Morpheme Database of Graded Vocabulary for HSK as the experimental materials to survey the family problems of the polysemous morphemes. The results find that the polysemous characteristic of morphemes has a great influence on foreigners＇ word acquisition. Based on the findings, we put forward ＂morpheme teaching＂ should be targeted. Especially for ＂polysemous morphemes＂, we need adopt appropriate teaching strategies according to the characteristics of both the morphemes themselves and those of their family members so that the concept of ＂morpheme teaching＂ could be carried out effectively.
