假如你上周末参加了某旅行社组织的所谓生态游，你觉得名不副实。请你根据下表内容把自己经历的这次生态游和对真正生态游的看法写出来。

　　所谓的生态游：

　　欣赏风景，享受新鲜空气

　　有人摘花、捉鸟、乱扔垃圾

　　真正的生态游

　　享受自然，同时也是一种责任

　　要保护自然，保护野生动物

　　带走美好回忆，留下青山绿水

　　Last weekend I went on an eco-travel with a travel agency. All the way we enjoyed the beautiful scenery and fresh air. But a few of us picked flowers as while going sightseeing. Some even tried to catch the birds they saw. What was worse, many tourists threw rubbish here and there. The rubbish may do harm to wildlife there.

　　vandalism 对公共财物的有意破坏

　　Dear Editor,

　　Recently graffiti has become more noticeable in my college. I feel quite annoyed at them, especially when some of my classmates praise them as a kind of so-called art. Confronted with this impolite phenomenon, I can’t help asking myself: what is wrong with today’s teenagers?

　　In my opinion, graffiti is a form of vandalism. They are a mess and are ugly to look at. Meanwhile, walls are public places, and they should not be used to express personal views and feelings.

　　I really think vandalism should be stopped, and those who refuse to stop this bad practice should be punished. We should clear away these ugly expressions and drawings so that our college may return to its true self--a clean, quiet place for study, teaching and research.

　　Yours,

　　Li Ming
