Question

We still remember once _________ round the famous tower when we were young.

A．having taken	B．to be taken
C．having been taken	D．to have taken

Answer 1

C

试题分析：句意：我们仍然记得当我们年轻的时候，我们曾经被领着参观著名的塔。这里是短语remember to do记得去做某事，表示将要做的事情；remember doing/having done记得做过某事，表示事情已经做过了；这里句子的主语与take之间是被动关系，故排除AD；根据句意可知这是过去的事情，所以事情已经发生了，故选C。
