Every human being has duty to develop his courage to the fullest.

human being还是human beings? Every plant,animal,and human being needs water to stay alive.为何need要加s I long,as does every human being,to be at home wherever I find myself It is accessible to every human being in existence .怎么翻译? Every human being has duty to develop his courage to the fullest. human being right? human being英语翻译 human being !是什么意思? human being怎么读 Every plant,animal,and human being needs water to stay alive.请问 这里为什么要用being? human和human being有什么区别? human beings与human being的区别 people和human,human being的区别 ‘Whether sixty or sixteen,there is in every human being's heart the lure of wonders’的出处?‘Whether sixty or sixteen,there is in every human being's heart the lure of wonders’的出处？马上就要 Every human being,no matter what he is doing,gives off body heat.这一句应该怎么译? 当human being表示人类时 用human being造句 being VS human beings 区别! fellow human being什么意思
