你为什么。。。？

A：你为什么学习汉语？
B：因为我看看，中国人无处不在。甚至在我的国家。中国商店也有很多。所以对我，汉语是有用的。我去中国商店买东西的时候，可以用汉语说的。也许下一次我去到中国，我会跟中国人轻松地谈谈[这‘地’怎么说? 'de' or 'di' or 'dei'?]。 [di as in 弟]

A：为什么你在会计专业报名呢？我们不是同意一起学习数学吗？你喜欢学会计吗？
B：冷静下来。不要问一次很多的问题啦。你先检查大学的网站。那。。。数学已经没有空间，对不对？这就是我为什么在会计报名的原因。其实，我会计比数学很喜欢。而且我觉得会计比数学有一点点容易。

A: Why do you study CHinese? 为什么你要学中文?
B: Because from what I observe, 因為在我观察时,

Chinese people are everywhere. 見到華人无处不在 [It's like calling a Scotsman an Englishman]

Even in my own country. 也包括我国在內.

So Chinese language is useful for me. 对我來說, 中文很有用.

When I go to Chinese stores, 当我去華商时,

I could use Chinese language to speak. 我可以用中文来交談.  [Most probably they speak Cantonese]

And maybe next time I go to CHina, 也許下一次到中国时,

I could converse easily with the people there. 我就很容易跟本地人接触.

A: Why did you enrolled in Accounting Programme? 为什么你在会计课 报名呢?

Didn't we agree to study Maths together? 我们不是同意去学数学嗎?

Do you like Accounting better? 你更喜欢会計嗎?
B: Calm down. /不要生气啊/靜一靜/

Dont ask a lot of questions at a time. 不要这么 /啰嗦/煩/ or more precisely, 这时不要問的太多,

Why dont you like at the website first? 不如先看看网站上吧?

See... 你看

there's no space left in that programme right? 数学那班沒空了嗎?

That's the reason I enrolled in Accounting programme instead. 所以去会計那辺报名.  [To translate directly into English is not the way to express in this Chinese conversation]

Actually, 其实

I like Accounting better than Maths. 我更加喜欢会計. [No need to translate Maths.  It's understood from context and be more natural in the conversation, otherwise you sound pedantic.]

I also think that Accounting is easier. 我也认为会計比較容易.
