单选题 Locke"s Chinese ancestry presents a double-edged sword situation. As a political figure, he cannot go overboard with his intimacy for China and its culture; otherwise, it will be difficult for him to get approval from politicians in the United States.
【正确答案】 D
【答案解析】解析：句意：骆家辉的中国血统带来了一个双刃剑问题。作为政坛人物，他不能过分表示自己与中国以及中国文化的亲密联系，否则他就很难获得美国政治家们的认同。ancestry意为“祖先，血统”。nomination“提名，任命”，cultural insight“文化洞察力”，cultural tradition“文化传统”，都与原词的意思相距甚远。只有pedigree有“血统，家谱”之意，故选D。
