23.Heby his sister at that moment.
A
A.happened to see
B
B.was happened to see
C
C.washappened to be seen
D
D.happened to be seen
答案解析
正确答案：D
解析：
23.【翻译】 他那时刚好被他的姐姐看见了.【精析】D根据句中的时间状语at that moment （在那时）可知，本句应用一般过去时，表示发生在过去的事情 happen在句中意为“碰巧.恰好”，为不及物动词，无被动形式，故可首先排除B、C两项=happen to do sth,为固定用 法，意为“碰巧发生某事”。根据句意和句中的by his sister可知，主语He与动词see之间是逻辑上的动宾关系，所以 此处应用不定式的被动式。故选D：
