S: 嗯来*自-优=尔,论:文+网www.chuibin.com

T1: 在最下面是思辨=

In this excerpt, T1 first mentioned terms of critical thinking and its carrier。 And then T1 introduced a pyramid approach to facilitate critical thinking by a foreign scholar。 An advice-giver with profound knowledge obviously constructs T1’s knowledgeable expert identity。 In addition, what T1 had raised was reconfirmed by S, although S may have limitations in certain professional fields。 This kind of confirmation from other researchers also consolidates T1’s identity as a knowledgeable expert。
