hints：Cuba;Puerto Rico; Guam;Philippines
After a brief war with Spain in 1898, the U.S. controlled several Spanish colonies, Cuba, Puerto Rico, Guam and the Philippines. Officially, the United States encouraged them to become selfgoverning. In reality, the United States kept control. Idealism in foreign policy co-existed with the desire to prevent European powers from acquiring territories that might enable them to project military power toward the United States. Americans also sought new markets in which they could sell their goods. By the end of the 19th century, the U.S. was beginning to emerge as a growing world power.
与西班牙在1898年的短暂战争后，美国控制了几个西班牙殖民地古巴，波多黎各，关岛和菲律宾。据官方统计，美国鼓励他们自我管理。实际上，美国保持控制。外国政策里的理想主义与防止可能会导致欧洲力量得到领土而向美国动用武装力量的意愿共存。美国人也寻求新的市场，他们可以出售自己的商品。到19世纪末，美国开始出现越来越多的世界强国。
