these trees are so special thati am determned to do"as much as"i can to save themdo as much as one can to ...这是固定短语,意思是：尽某人全力做某事整个句子翻译：这些树木太特别了,以至于我决定尽全力...哦，谢谢，我觉得do as much as one can 应该不要to 是不是？你说的是前面还是后面？前面的to ：be determined to do sth, 所以to 必须有后面的to ：do as much as one can to 尽全力做某事。。。 to后面是尽全力具体做了什么，只要后面有具体的动作，就还是必须有to所以前面和后面的to都必须有。
