推 clydechen:B
→ clydechen:字句為非限定
→ dunchee:"Practical English Usage" by Michael Swan, 3e
→ dunchee:130 cleft sentences (1): ....
→ dunchee:-> 1 ...
C大用非限定講法選(b)
P大指的PEU用強調講法選的是(a)
那到底應該是(a)還是(b)???

PEU的例句:
Mary was the person who kept a pig in the garden shed.
The person who kept a pig in the garden shed was Mary.
A pig was what Mary kept in the garden shed.
You are the woman (that) I'll always love best,
Casablanca is a film (that) I watch again and again.

如果以PUE給的加強句 cleft sentences來看
先行詞都是簡單的the person， a pig， the woman，a film
跟原題給的先行詞this little English teacher from USA似乎有點不太一樣
不知道這樣的先詞還可以在PUE的加強句 cleft sentences用法中嗎?

所以應該是限定/加強句 cleft sentences(a) 還是 非限定(b)???

推 IrwinC:我覺得是那個USA把teacher&who隔開，所以不能用限定修飾

推 preikestolen:我也覺得是(b)是非限定用法，先行詞所指涉的東西已經
→ preikestolen:很清楚了，關代沒有特別幫到甚麼忙。
