urgent Urgent

coming
(see 係感官動詞,後面的動詞一般係不定式(come),若是形容動作進行中用現在分詞coming)

when
(句子中的when係子句標記(clause marker),來分別子句及主句,即when ...... ,係字句, 後面係主句 )

turning
(turning 係現在分詞)
簡單解釋如下
Participle phrase 係將兩個句子合埋一句,只保留一個動詞,另一句轉做分詞
(Subject相同做前面,不同相做後面)
Participle phrase 轉時式做法
(1) Present Tense/ Past Tense
----(a) Active 變成ing (如play/played 變成playing)
----(b) Passive 變成 p.p. / being p.p.
(2) Present Perfect Tense/ Past Perfect Tense
----(a) Active 變成 having + p.p. (如 has/had played 變成having played)
----(b) Passive 變成 having + been + p.p. (如 has/had been played 變成having been played)

講番你個句
when he turned/was turning the corner, he was talking to .......(Subject相同做前面)
when turning the corner, he was talking to .......

that
that 有很多用法,句子中的that 後出現S+V 係noun clause(六種noun clause中的object of the verb)

who
who都係有很多用法,
那句係Relaive Clause/Adj. Clause
首先分別邊句係主句,邊句係子句,找有關的noun 名詞轉
人(who - subject) (whom - object)
死物(which - subject / object)
that 百搭
whose(人的)
of which (死物的)
還有.......
