问题补充：
—When did you?
--I the airport at 8 a.m. this morning.
A. arrive, arrived at
B. get to, got to
C. reach, reached
D. arrive, got
答案：
(答案→)A. arrive, arrived at
B. get to, got to
C. reach, reached
D. arrive, got
解析：句意：你是何时到的？——我是今天上午八点到的机场。Arrive是不及物动词后面必须加介词in/at才能加宾语，get to =reach 都表示到达，他们后面直接带宾语，结合句意，故选A.
