an.dan怎么写 _dan

1.英文作文要怎么写Dear Mary:
【an.dan怎么写】Hello, My name is Liu Dan. I am an eighteen year girl living in Da Lian, China. I would love to be your pen pal.
Frist of all, I would like to tell you a couple of things about myself. I am in my last year of high school. My English is ok. And I want to be an engineer after I graduate from college/university. I like to sing and collect stamps. So far I have collected more than three hundred different stamps, most of which are Chinese. I guess if we become pen pals I would be able to get some American stamps from your letters.
What about you? What are some of your interests? What's your daily life like?
Looking forward to hearing from you soon.
Liu Dan
P.S. I've attached a recent photo of mine as well as five Chinese stamps. Hope you like them.
2.陕西的英文翻译为什么是shaanxi如果依据汉语拼音（汉语拼音是以拉丁字母书写中国地名的标准），「山西」和「陕西」都会变成「Shanxi」，这样基本的地名都无法区分是不行的。
所以，借用别的拼音系统，从国语罗马字方案中借来「陕 shaan」这个拼式，替换汉语拼音「Shanxi」中有歧义的「shan」，构成「Shaanxi（陕西）」，使其与「Shanxi（山西）」区分。
扩展资料：
国语罗马字是少有的不依赖数字或特殊符号便可标记声调的拉丁化/拼音方案。至于国语罗马字为什么会选择这样标注上声（三声），大概和上声往往较长、较转折确实有关。
另外，邮政式拼音也区分「山西」和「陕西」，它分别使用「Shansi」和「Shensi」。不过，邮政式拼音不是一个规则明确的完整的拼音体系，而且「shen」与汉语拼音冲突。
