关于ecosystem,humans,food的200字英语作文,急 英语翻译There is growing concern amongst many natural scientists that human interventions are altering the capacity of ecosystem to provide goods and services needed for humans. ecosystem-scale什么意思 Partnership Ecosystem 如何翻译? a catchment-based ecosystem approach human humans区别（满意追加）用法上有没有什么区别?有一个例子;( )made the world.是添humans的,可为什么呢、就是关于这些,谁可以多解释一下?满意追加!不好意思，是human不是humans both dolphins and humans have these,eight letters一个单词，可能是复数f开头，倒数第三个是n human beings humans区别? humans=human beings? human humans的区别 what for humans living? 翻译“a vital part of a balanced ecosystem” 求雅思阅读这两道题到底是F还是NG原文中有almost,题目中没有almost,其他都一样..答案给的是NG,我觉得是Flike humans,crows are usually right handed when it comes to tasks such as making tools 题目是like humans,cro 为什么wildlife不可数?但是animal,ecosystem and so on可数?实在不清楚英语中可数和不可数的逻辑,但是为什么wildlife是抽象名词，animal 和 ecosystem不是抽象名词，个人觉得ecosystem比wildlife更抽象，所以 关于凸透镜“4f invasive species ,what this means for humans Should Animals Be Trained to Help Humans humans'和human's有什么不同
