Question

1.My boss was very angry when his car broke down again ,________ at the garage only a week before.
B.having serviced it C.having had it serviced
A.D两选项我已经排除.可我有疑问：
后面逗号开始,可以填because he had serviced it ,删去because和he,就成having serviced it,这样就选B,
但后面逗号开始,如果填because he had had it serviced,删去because和he,就成having had it serviced ,这样就选C,
请问：这题应选择什么?为什么?

Answer 1

.having had it serviced （已经让人对它进行了维修）, 这是分词结构,动作发生在he was angry以前,所以就用完成式的分词结构== for he had had it serviced （这是原因状语从句）
have sth done ------使sth被做
