1. 分裂句 (Cleft Sentence)：It is/was + 被強調成分 + that…

例：Mary married John in America yesterday. (未強調)


A) 強調主詞 Mary → 分裂出主詞 Mary → 套入It is ...that之間。
→ It was Mary that/who married John in America yesterday. (and not Jean.)
　 (是 Mary 昨天在美國與 John 結婚。/ 昨天在美國與 John 結婚的是 Mary。)

B) 強調受詞 John → 分裂出受詞 John → 套入It is ...that之間。
→ It was John that/who(m) Marry married in America yesterday. (and not Tom.)
　 (昨天 Mary 在美國所嫁的人是 John。)

C) 強調地點 in America → 分裂出地點副詞 in America → 套入It is ...that之間。
→ It was in America that Mary married John yesterday. (and not in Taiwan.)
　 ( Mary 昨天與 John 結婚的地方是在美國。/ Mary 昨天與 John 是在美國結婚的。)

D) 強調時間 yesterday → 分裂出時間副詞 yesterday → 套入It is ...that之間。
→ It was yesterday that Mary married John in America. (and not today.)
　 (是 昨天 Mary 在美國與 John 結婚。/ Mary 是昨天在美國與 John 結婚的。)

2. 準分裂句 (Pseudo-cleft Sentence)：What…is/was +…被強調成分… (what視為單數)

例1. My right hand hurts. (未強調)

A) 強調主詞 My right hand → 分離套入句型 What ...is...
→ What hurts is my right hand.

例2. He likes Marys style. (未強調)

B) 強調受詞 Marys style → 分離套入句型What ...is...
→ What he likes is Marys style.

例3. He lingered around after the movie finished. (未強調)

C) 強調動詞 linger → 分離套入句型What S + V (eg, do) … was (to) ...
→ What he did after the movie finished was (to) linger around.
= All (that) he did after the movie finished was (to) linger around. (that當受詞才可省)
