例如：- He didn't tell me what had happened.- I am not sure about what she is talking about.3. 作表语：表语从句可以作为主句的表语，进一步说明主语的情况、性质或特点。
例如：- His dream is to become a famous singer.- The question is whether we should support the new policy.四、表语从句的语序表语从句的语序一般是陈述语序，即主语+谓语。

）关系代词 who, what, which, whom, whose, whatever, whoever, whomever, whichever等；关系副词 when, where, why, how, however, whenever, wherever 等。

分析句子结构可知：系动词is后面应为表语从句，动词enjoy缺少宾语；where、why属于连接副词，不能做宾语；that在表语从句中不充当句子成分，what属于连接代词，引导这个表语从句，并在句中做enjoy的宾语。
故A项正确。

故选D。
