阅读汉语是很难

阅读汉语很难！

阅读汉语真是难！

阅读汉语很难。

阅读汉语是很难的。

zhè shì wǒ de hàn yǔ katon ; ))

这是我的汉语卡通。（ka3 tong1 ）

这个句子我觉得不通。

“这是卡通。”

“这是汉语漫画”

“这是我画的汉语漫画”

1. 阅读读懂汉语(是)很超难

The meaning of the sentence is 100% correct; but, it's not like our daily words.
Normally, we will say: zhè ge chao nán. As a title, I think '读懂汉语超难' is more fun.

2. zhè shì wǒ de hàn yǔ katon ; ))

I think the form of th picture that u perform is 漫画 (Comic), not 卡通 (Cartoon).

3. 哎，你会阅读吗？

We always suprise sb who do understand other languages. We won't ask 'do u read', but 'do u understand (你看得懂吗)?'。 Just be careful, the same sentence with different tone will show totally different meaning-from surprising to offending.

4. About '哎'- the onomatopoeia

It's very cute and mündliche word in sentence. But '哎' is showing sigh. As the meaing that you wanna show surprising, it's better using '咦' to indicate question+surprising; or Taiwanese girl will said '哇' to demonstrate  'highly praising'.

I think it's quiet difficult to speak a language as native speaker. But u did well!

I would like to share my experience to u. There was one time that I run in the street. Suddenly, it was raining. I went into a shop and the owner treat me a coffee. I was a little bit shine, thus, later I said: Entschuldigung. Jetzt sind die Regen klein, ich hätte gern zu erste gehen.

But the boss said: Nein~~

I was shock and thinking about what's wrong???

The boss said: Jetzt sind die Regen langsam, nicht klein....囧rz

Guess what, there is no any chinese-speaking friends know this, except the boss told me what we said is wrong.
