明明从滑梯上滑下去了。

[querido]

Whew! I worked hard on this one! It was the very last item in a children's text I'm about to finish.

Trying to translate this, which I presumed to be a sentence, I kept getting a sentence fragment:

"obviously slid (down) from the (children's) slide"

Then, I suddenly realized that 明明 is a name.

Mingming slid down from the slide! Ha ha!

Let that be a lesson!

Doesn't similar situation exist in other languages?

Like "Patience has brought us a success" perhaps?

Recognising the grammatical subject in Modern Chinese is usually quite easy, it tends to come first. If 明明 had made any sense as an adverb in the sentence given (it does not), it would more naturally have been placed closer to the verb 滑下 with or without the adverbial particle (地). If you have trouble with subjects in Modern Chinese, I would advise keeping away from Classical Chinese which can be especially painful in this regard.
