英文很地道，用豐富的語法結構和詞匯

(這是我的弱點)。這裏隻討論一下幾個詞語用法問題。

 

1. Lawn and flower beds are planted by human, and they are too specific.

 

2. the humming bird is categorized by nature - delete "by the nature", because it is actually categorized by human (taxonomists).

 

3. Last sentence is completely off. But it is very interesting from the biological point of view. I can't help laughing about it. .
