问题补充：

What he said is not to the point we should focus on constructing a harmonious society.

A. that

B. which

C. where

D. if

答案：

(答案→)A. that

B. which

C. where

D. if

解析：考察同位语从句。本题同位语从句的先行词是the point后面的同位语从句that we should focus on constructing a harmonious society对前面的名词point的内容进行解释说明，that在句中不充当任何成分，也没有实际的含义，只起引导和连接的作用。If不能引导同位语从句，which和where的语义和句子不符。句意：他说的话没有切中要点，就是我们要集中注意力建设和谐社会。故A正确。
