问题补充：

seemed surprising to us washe came out first in the speaking competition.

A. It; that

B. What; what

C. It ; what

D. What; that

答案：

A. It; that

B. What; what

C. It ; what

(答案→)D. What; that

解析：考查主语从句和表语从句。前文主语从句 seemed surprising to us缺少主语，it只能用作形式主语，文中没有指代内容，故只能用what作主语。下文为表语从句，不缺少句子成分，故用that做引导词。选D。
