问题描述：
while you were not in, a person( ) himself jcak phoned you
A called B calling C to call D having called
答
B
当你不在的时候，一个自称jcakd 的人打了电话给你
关键就是这个himself ，自己称自己，肯定是主动拉，所以要用-ing
如果没有himself则用called，别人叫的，所以要用被动
a person calling himself jcak 一个自称是jcak的人
a person called jcak 一个叫jcak的人 （别人叫的）
此处jcak 应该是Jack（杰克）吧
答
答案是B。
用现在分词calling是因为后面有宾语himself。如果没有himself，就填called.
答
calling 现在分词做himself的定语
答
A
