问题：请问这几个单词的区别requirerequestneeddema? 
请问这几个的区别require request need demand都是要求的意思，请问用法以及意义有何区别与联系？最好有EXAMPLE，请详细点，谢谢
回答： mand 的含义是“强烈要求”；如果主语是人，这个词的含义可以解释为“据权要求”；如果主语是物，这个词的含义可以解释为“需要”或“要求”Whenever the Italian city-states were at war with each other,Hawkwood used to hire his soldiers to princes who were willing to pay the high price he demaned.每逢意大利的城邦互相打仗时，霍克伍德常把自己的士兵租给愿意付给他所要求的很高的价钱的王子们。When anyone opens a current account at a bank,he is lending the bank money, repayment of which he may demand at any time, either in cash or by drawing a cheque in fevour of another person.任何人在银行开了活期存款户头时，他就是把钱借给了银行，但他可以随时提取这些钱，或者以现金的方式，或者开一张款子付给别人的支票。This work demands care and patience.这种工作要求细心和耐心。 quire 虽然有时可以与demand换用，但是require 的确切含义应当是“对所要求的事”要绝对服从，或者说这种“要求”带有或规章的强迫性In future,astronauts will be required to descend from a spaceship while it is still in space and to return to it.将来，将要求宇航员从停在太空里的飞船中下来并且能回到飞船中去。Such undertakings require the precise planning and foresight of military operations.这样的事情要求有军方行动一般的周密部署和预见。注：demand和require 的宾语从句用虚拟语气[(should) do ] quest侧重客气地表示请求，有礼貌地表示愿望We request the honour of your company at dinner."谨备便酌,敬请光临。" ed为最普通的需要,一般不与上述词语区别.
