Question

The teacher，with 6 girls and 8 boys of her class, __________ visiting a museum when the earthquakes truck.

A.was               B.were              C.had been           D.would be

Answer 1

A 

解析:

谓语动词的单复数形式由主语the teacher决定，不受插入语with 6 girls and 8 boys of her class的影响，根据本题语境应采用过去进行时表示地震发生时教师正在游览博物馆，所以本题只能填入was。
