起初我发现中文不是很简单

中文里是没有发现。 英文就要把not 放到did后面。 老师讲过

不论什么时候开始，重要的是开始之后就不要停止。不论什么时候结束，重要的是结束之后就不要悔恨。

倒装 Subject-Verb inversion
1.Here is a diesel-engine car that will out-gun many of its petrol-engine rivals.
2.Across the table sat a group of three boisterous lads and further along, but too far for conversation, was Dominic.
3.Here lies the greatest pleasure of greenhouse gardening.
条件
Conditions: The Subject must be realized as a noun phrase, and should generally be longer than the Verb. Inserting existential there is sometimes possible.
倒装句一般主语比较长（长，所以主语内涵多，参考例句）～ 倒装也是为了强调。哪个放前面，强调哪个。西方学术作文都是喜欢强调的东西放在前面（中文反而是在结尾）。

否定前置 negative fronting 一般都是adverb
2.I've never seen such careless work.
Never have I seen such careless work.
2.I've rarely eaten such a delicious meal.
Rarely have I eaten such a delicious meal.
Note:The subject and verb change position.
一般强调否定感觉
this can express surprise, disapproval etc.

If the sentence does not have an auxiliary verb, this type of simple inversion is not possible. Instead, an auxiliary must be introduced into the sentence in order to allow inversion:
如果句子没有auxiliary (am is are do does),倒置将不可能，所以解决方案，可以自己加 。。
a.Samenjoys the paper.- Statement with the non-auxiliary verbenjoysb.
*Enjoys Samthe paper?- This is incorrect; simple inversion not possible with this type of verb
c.Does Samenjoy the paper?- The sentence formulated with the auxiliarydoesnow allows inversion
倒装成功～ 但是却成了问句。所以一般倒装的都是adverb..不是auxiliary

根据楼主例句
at first I didn't find Chinese easy .. 好了。结束。。大神继续补充吧
