请问second与secondary 有什么不同，谢谢！
1. second侧重顺序，意思是“第二”，与“第一”“第三”等相对比而言。如：
Argentina is the second biggest nation in Latin America. 阿根廷是拉丁美洲第二大国。
Several candidates were called for a second interview. 有几个候选人被叫来作第二次应聘。
His second suggestion was little better than his first. 他的第二个建议比第一个好不了多少。
2. secondary侧重重要程度或价值，意思是“第二位的”“次要的”。如：
Other people’s opinions are secondary—it’s my opinion that counts. 别的人的建议是次要的，我的建议才要紧。
What matters is the size of the office. The location is of secondary importance. 重要是要看办公室的大小，地方是次要的。
