延長句子方法系列(2)d：介詞短語作名詞修飾語或狀語

要係英文作文度成功,一定要識prepositional phrases,介詞短語. 

其實由細細個學英文,已經有好多介詞短語.例如:

Some of us have to go to summer school.

句中的of us,便是preposiitonal phrase, 修飾some呢個代名詞(pronoun), 因此of us的作用是adjective.

又例如呢句:

If enough of you are interested, we'll organize a trip to the theatre. 

當中的enough也是代詞,of you是修飾它的介詞短語/形容詞.

介詞短語可作形容詞,又可作副詞,修飾動詞.例如呢句細細個學的英文:

I go to school.

句中的to school是介詞短語,修飾go,所以是副詞.

又例如past,很多人不知可以是介詞,修飾動詞:

We walked out of the gallows yard, past the condemned cells with their waiting prisoners, into the big central yard of the prison.

上句共有三個介詞短語(out of the gallows yard, past the condemned cells.., into the big central yard...), out,past和into也修飾walked. 注意,同時間後兩個的介詞短語裡也有介詞短語: with their waiting prisoners修飾cells, of the prison修飾yard.

介詞短語又可修飾句子,作副詞.例如:

With the exam approaching, it's a good idea to review your notes.

這種with的用法有「因為」的意思, 也可表達雖然：

With all her faults, she's still a really good friend.

總之,唔識用prepositional phrase,永遠也寫不出好英文.
