這句中的over解什麼?

1.
原意是over two years ago = 兩年多前
然後又想附加(資料)那兩年前的事件是那(次)July 1 Protest
所以正確的寫法應是
... of Occupy Central movement volunteer chan yuk fung for a July 1 protest over two years ago.

2.
因為形容詞是形容那object(受詞)而不是subject(主詞)
再者其實句子省略了...the activities to be fun, inspiring, and thought provoking. 並且用"xx"引號來突顯這些形容是found到的主題，因此把無關重要的文法用詞省略了，這亦是現代英語的取向。你把越新近和越時代性的文章跟標準文法對比便會發覺更多省略、調亂、混用等情況。

1.
對不起
重看寫法
理解應該是
over "A JULY1 PROTECT"是指「由於」"這件事"。

首先要說：你的句子應是

Their inquiry follows the arrest and court appearance of Occupy Central movement volunteer Melody Chan Yuk-fung over a July 1 protest two years ago.

為甚麼用over而不是用on

因為over所帶出的不是日子，而是相關事件"a July 1 protest" (暫不理會two years ago)

over其中一個用法，就是帶出有關事件，如：Cambridge Dictionary Online就有幾例

over
preposition (CONNECTED WITH) Definition connected with or about:
There's no point in arguing over something so unimportant.
I need time to talk/think over your proposal (= to discuss/consider it carefully).
The legal battle was over who should have custody of the child.


２）
而our member found the activities 'fun', 'inspiring', and 'thought provoking'.

當然你可以說
our member found the activities were 'fun', 'inspiring', and 'thought provoking'.

但find這字，其中一種用法是

find + object + adjective，如：

I find him smart and kind.

希望幫到你！

一句句子不能有兩個verb
