First notebook entry: Introducing myself

你好，我叫Shane和我的中文名字叫白龙。我是爱尔兰人。我学习中文因为十三亿中国人说中文。有13亿人在说汉语（备注：中国人本来就说中文撒，你想表达的是：世界上有13亿人在说中文。而不是因为中国人说中文，就想学汉中文。我们常说：说汉语，或者用中文表达）

Hello,Shane!

[1]In Chinese we use "大家好/你们好" to say "hi there/hello,everyone",rather than "你好".

[2]When you start a new sentence in Chinese,you can never use "和".Though the Chinese character has the same meaning with "and",they are totally different grammatically.That's to say,"和" cannot be used as a conjunction.

[3]Adverbial clause of cause in Chinese is formed in two particular ways.

a.cause goes first,then effect."因为/由于···，所以···"

b.effect goes first,then cause."之所以(the three characters can be omited)···，是因为···"

Hope it's helpful.  yours,Kevin.     Skype:taichi123kevin
