另外请教前辈，这题我看不出哪里可判断用ed or ing ,答案是A
Ethnocentrism is the view that one’s own culture is better than all the others; it is the way all people feel about themselves as _________outsiders.
(A) compared to
(B) comparing to
(C) are compared to
(D) they compare to

It is the way all people feel about themselvesas "they are" compared to outsiders. as 是 (conj.) 连接词，子句中的 S + verb to be "they are"省略人在这句中是被比较的，如要主动要改写为 as comparing "themselves" to outsiders, 因为 compare Ato B (vt) 是即物动词，后面要接受词所以 (A) compared to 是正解"they are" = "the people are"提及改写的为(B)选项。 及物动词，字误更正
