介係詞(against)對 介係詞(for)

Than 對等連結詞 兩邊結構一致 介系詞對介系詞

were against反對 the idea than were  for贊成  it. 

But more of you were...

*補充:動詞對等用法 1.than—比...

英文不好。但我有查到for有「贊成」的意思。前面是講很多人反對，然後接then were for it我覺得是講對比於贊成(for)這件事(it)。

Recently we asked for your opinions about paying students to improve school attendance or performance on tests. Some American __41__ are doing this. But more of you were against the idea than were __42__ it. Some people said paying students sends a message that __43__ is the only valuable reward. Steven from China says students should study for knowledge. Money may improve performance in the short term, he says, but we should think about the __44__. Zhao Jing Tao, a college student in China, thought of an old saying. __45__ students is like "drinking poison to end thirst" -- trying to solve a problem without considering the effects.
