1. The problems that you mentioned____ to the attention of our
housekeeping department.
(A) will bring (B) brought (C) be brought (D) have been brought
正解： D have been brought
我知道bring 是及物V. 但后面没受词，A、B 去掉，要选被动式
但未何不能选 (C) ?
2. We're sorry for the inconvenience and annoyance this ___ caused.
(A) incidence (B) incident (C)incidental (D) incidentally
正解：B
我选(D)，想说用来修饰caused ....
书中的解法我看不懂><
"this caused"是修饰 the invonvenience~~annoyance的关代，
省略了which /that，空格受到this的修饰同时，要能充当关系语句的主词。"
各位高手拜托了~~ 谢谢
