many places of interest 为什么interest后面不能加s

many places of interest 为什么interest后面不能加s “places of interest”place后面一定要加s吗 翻译many well --known places of interest There are many places of interest. enjoys many world-famous places of interest places of interest 名胜,这短语中interest加s吗?有什么区别? the places of interest这里的interest能不能加s的啊? "an interesting places=a places of interest"有a或an为什么place还加s places of interest 原文 some places of interest places of interest中的interest是什么意思? 请根据It's very beautiful and there are many places of interest
