Ludwig Wittgenstein提出了“家族相似性”观点,推翻了传统的关于属性必须是“全范畴的”观点,指出属于统一范畴的成员不可能拥有该范畴的全部属性,相反,各成员的属性是相互连接的交错、相互联系的。将家族相似性运用于英语教学中对于英语语言习得有很大帮助。 Ludwig Wittgenstein proposed the view of “family similarity ” and overturned the traditional view that n “” properties must be “whole n scope ”, pointing out that it is impossible for members belonging to a unified category to possess all the attributes of the category; on the contrary, Attributes are interlaced, interrelated. The use of family similarity in English teaching is of great help to English language acquisition.
