一：[sufficient]sufficient 和adequate的区别二者都有丰富的意思,但有什么不同呢
sufficient无比较等级,作为形容词有“足够的,充分的”意思,常与for或与to+动词原形连用They haven"t saved money sufficient for a new house.他们还没有存够买新房的钱.His income is not sufficient to support his family.他的收入不够养家.adequate作为形容词除了有“适当的,充分的,足够的”之意外,还有“可以胜任的”的意思
二：[sufficient]enough,sufficient和ample的区别?请不要复制词典的内容!最好给出一些例子来,
enough及sufficient同ample比较容易区分.前者是足够,后者是充裕意思.enough及sufficient都是足够,比较明显的是前者较通用,后者太正式,文字味重.另外,他们的否定式不一样.sufficient的否定式是insufficient.根据The Columbia Guide to Standard American English的解释,enough同sufficient的区别为：Using sufficient instead of enough as a noun is clumsy and sounds old-fashioned,as in Thank you,but I’ve had sufficient,and even as an adjective sufficient almost always sounds stiffer and more Formal than enough,as in I have sufficient information to write the article,as does insufficient for a negative:compare We don’t have enough time to reach the station with We have insufficient time to reach the station.In any case,use either sufficient or enough,depending on the level you seek,but don’t use both together,as in This flour is sufficient enough for today’s baking.Sufficient is sufficient.Enough’s enough.See AMPLE ENOUGH.
