I'll assume u mean by a, i or u :الفتحة و الكسرة و الضمة An arabic word, let's say شجرة only has a limited ways of reading, could b only 1(شَجَرَة no other way is correct). If u r used 2 speaking arabic, u may b able 2 memorize how it's read if there's 1 way or (from the context)which one of the ways is correct. Sorry, i don't speak any chinese, i hope u can understand my english.

I don't understand why you want to read Arabic books when you don't even know how to read words yet. That is just pointless. As for learning how to read without the short vowels, it takes time and a lot of work. It's something that comes out naturally to you as you learn more Arabic words and figure out that they always have patterns (one of the best things about it!) to follow. Good luck!

Because we Arabs are used to how the words are pronounced so we don't need التشكيل and if a word has more than a way for pronouncing it the context defines the way it should be pronounced For example : علي في المنزل ( 阿里在家） الكتاب على الطاولة （在桌上放着一本书） Check out this website : http://tashkeel.googlelabs.com/ You enter the Arabic sentence and it puts التشكيل marks on it, I think it will really help you 因为我们习惯了怎么读每个词所以无 تشكيل 我们知道怎么读这个词，如果一个词有更多的发音，我们从背景知道怎么读这个词。 比如 : علي في المنزل 阿里在家 الكتاب على الطاولة 桌上放着一本书 如果你有困难读一个句子 你可以把它放在这个网站：http://tashkeel.googlelabs.com/ 这个网站让你知道怎么读每个词。 I hope it helps you 如果你有一个问题 可以加我 Skype : hesham.salah6 咱们俩可以互相帮助 Hesham 再见！

When you studying the Arabic language, don't make any comparison between Arabic and English,in Arabic we have three vowels: (alif: أ , wow : و , ya: ي ).
