英文文法問題?

呢個結構叫 participle clause，加o係名詞後意思好似 relative clause咁，第一句因為只得一句 participle clause，就用第二句講：

he e-mailed electronic journals advocating democratic reform.

其實 he 做左o既係 e-mailed electronic journals。而 journals 內容係乜？就係 advocating democratic reform。如果用 defining relative clause 表達，就係

he e-mailed electronic journals which advocate democratic reform.
