[學生常犯的寫作錯誤 2] 所有格加動名詞 (Using Possessives with Gerunds)

Many people believe that students wearing uniform is beneficial.
上面的句子有錯誤嗎?

在檢查錯誤之前，先來分析此句:

Many people 是主詞，believe 是及物動詞，that students wearing uniforms is beneficial 是名詞子句當受詞。

That 是連詞，連接名詞子句但可省略。Students wearing uniform 是動名詞片語當名詞子句的主詞，is 是連綴動詞，beneficial 是形容詞 (主詞補語)。

======================

一切看起來正常，但是名詞子句的主詞 students wearing uniforms (學生穿制服) 有出現兩個問題。

第一，有些人會把 wearing uniforms 誤認為現在分詞/形容詞片語 (students who wear uniforms -> students wearing uniforms)。

但是這裡 students wearing uniforms 應該是當作動名詞片語。

---------------------------------------

第二，students 是名詞，但 wearing uniform 是動名詞，所以文法「正確」的寫法應該是 students’ (所有格) wearing uniforms。

但很沒人會寫 students’ wearing uniforms/student’s wearing of uniforms，因為過度強調 "學生的" 而作者希望把重點放在穿著制服上，也有一些母語者會覺得這樣子的寫法拖泥帶水並且不自然，可能會造成混: http://www.getitwriteonline.com/archive/022205posscasegerunds.htm

======================

Many people believe that wearing uniforms is beneficial for all students. [O]

Many people believe that school uniforms are beneficial for all students. [O]

Many people believe that all students should wear uniforms because of the numerous benefits. [O]

這三句的重點在於名詞子句的主詞清楚，不會造成任何的混淆而降低了閱讀的流暢度。

---------------------------------------

其他例句:

He resents Mary being promoted. [X] 不正確，除非 being promoted 是形容詞片語。

He resents Mary’s being promoted. [O] 文法正確，但不常見。

He resents Mary’s promotion. [O] 最自然的!

---------------------------------------

Thank you for you listening. [X] 不正確。

Thank you for your listening. [O] 文法正確，但不常見 (unidiomatic)!

Thank you for listening. [O] 最自然的!

---------------------------------------

I appreciate he participating in the event. [X] 不正確。

I appreciate him participating in the event. [X] 文法不正確，算是非正式用法。

I appreciate his participation in the event. [O] 最自然的!
