Question

The girl turned red when she ____ to answer the question. A.asked B.was asking C.was asked D.has as

Answer 1

选C，be asked to do sth，被叫去做某事。
因为turn是过去式，所以be也要用过去式，即was

Answer 2

C.was asked

被叫起来回答。

所以用被动。

Answer 3

选C 从句缺少谓语 而且是被动语态

Answer 4

选c，原来的短语是ask sb to do sth让某人做某事, 被动形式是be asked to do sth。这句话的意思是当让她去回答这个问题时，她的脸变红了！
