try to have done 的用法

I could have tried to have been more fun and sexy. (错误)I could have tried to be more fun and sexy.(正确)could have tried:1. 表示对过去情况的“推测”。2. 表示与过去不符的“虚拟语气”。本句语境是虚拟语气。主语是 I,自己对自己不需要推测。可以说try to do; 没有 try to have done 的说法,不符合逻辑。tr...

a换成one吗

You never see a police officer in this town, do you?如果把 a 换成 one,那么, one 肯定要重读的。那有可能是,根据否定范围或转移,never 否定 one,意思是:你看到决非一个警察,而是很多。意思与原来会大相径庭。You never see one police officer in this town, do you?

‘Crossroads of Europe’ is a catchphrase designation for the Balkans, conveying little more than unfamiliarity with the region by those who use it. conveying 的逻辑主语是 catchphrase designation,这是现在分词短语作定语。这不是问题,关键是by sb. 的含义。我把句子简化一下:This catchphrase designat...

education, excitement, agreement, invention的用法比较
