单选题 He is the kind of person who stops at nothing in order to ______ his own purpose.
【正确答案】 D
【答案解析】achieve one's purpose“达到某人的目的”，还可以说：accomplish (attain)one's purpose；fulfill (realize, effect, carry out, execute) one's purpose“实现目的”；promote the purpose“促进……目的”，用在句中语义不合适。reach one's purpose，不符合习惯上的表达方式。
