选A.
这句话等于说：The gold medal Liu Xiang has has been inspring the audience.His spirit has also been inspriring the audience.第一个has是实义动词,意为“拥有,得到”,Liu Xiang has其实是省略了引导词that/which的定语从句.第二个has是助动词,与been inspring构成现在完成进行时.
现在用副词短语not only...but also...把两句话连接起来.副词在句首时,句子要倒装,所以助动词has提前,就成了Not only has(助动词) the gold medal Liu Xiang has(实义动词) been inspiring the audience but also his spirtis.
