I am Chinese.为什么Chines前不用冠词a?都哪些国家的人,前面不用冠词?例如,他是一个英国人.她是一个美国人.等等我是中国人I'm Chinese我是美国人I am an American在这两个句子中Chinese和American显然都

I am sorry, but I do not read Chinese. I am learning to speak a little Chin I am Chinese boy.chinese为什么不能用china代替 I am a Chinese girl.为什么不用:I am an Chinese girl. 要表达我是中国人应该说I am Chinese为什么不说I am a Chinese? I am not Chinese boy I am not a Chinese 为什么后者要加a那 i am not chinese i am nativer chinese 为什么 I am Chinese中没有冠词a 任务型阅读（英语）Dear Mike：I am in Beijing,China now.My classes are going to start next week.I am going to study Chinese,maths and some other courses.I live with a Chinese student.He often helps me with my Chinese.My uncle is also in Chin i am proud i am a chinese I am Chinese.Chinese的词性 I am a Chinese还是I am Chinese 是i am a chinese 还是 i am chinese I am Chinese.I am a Chinese.哪个句子正确 为什么不能说I am an English?我们可以说I am a Chinese.和I am English. I am Chinese .nom student . I am good at Chinese. I am Chinese.VS I am an American.有人说：只有I am Chinese.没有（或者说不正规）I am a Chinese.那为什么有I am an American.(我认为有)顺便问下在“I am Chinese”中,Chinese是名词还是形容词?
