问题补充：
we were having at the party!
A. What wonderful time
B. What a wonderful time
C. How wonderful time
D. How a wonderful time
答案：
A. What wonderful time
(答案→)B. What a wonderful time
C. How wonderful time
D. How a wonderful time
解析：B 考查固定句型和感叹句的混合使用。have a good time“玩的开心”，a不能丢。排除A/C。感叹句的中心词time是名词，故用what引导感叹句。选B。
