英语某个特别位置介词的用法
我觉得“Mary wrote an article on why the team had failed to win the game.”里的on很别扭,介词怎么能这么用?另外一句,Writing an article on how London hotels treat people in wheelchairs.这里的on也一样.还有一个句子,There is disagreement among economists about what money is and how it can be measured.这个句子里面的about也是一样怪异.我翻找语法书,想第一句的on和后面由whu引导的那个宾语从句可不可以理解为介词短语,既介词+名词.就好象Mary is in the room里面的in the room.麻烦高手指导下.
