能说My nationality is China吗?或者My nationality is Chinese 哪个对呢? What’s your nationality?my nationality is korean My nationality is American//Chinese.句中为什么用American//Chinese, NATIONALITY是说CHINA 还是CHINESE? My nationality is English.这句话哪里需要改? 对what nationality are you?的回答可以是my nationnality is ... what is your nationality?应该回答china还是chinese?应该是chinese 但为什么? nationality 是填Chinese吗? Nationality 国籍应该写CHINA 还是CHINESE? nationality应填china还是chinese 填表 nationality 是应填China还是Chinese 填表时,Nationality是填Chinese/China?
