你可以想象他们一个是主观一个是客观,比如Fresh是形容带给你新鲜、干净感的东西fresh vegetable/fresh air/fresh fish而New则是客观上产生时间较短的东西new dress/new collection/new law还有就是词义,我认为“新鲜...之前我一直以为fresh是新鲜的意思，但是我在外国的词典上看到了一些造句反而弄不懂了 The original orders were cancelled and I was given fresh instructions.新的订单Fresh evidence has emerged that casts doubts on the men's conviction.新的证据There has been fresh fighting between police and demonstrators. 新的战斗They decided to move abroad and make a fresh start.新的开始The original orders were cancelled and I was given fresh instructions.这句因为之前有一个original order，所以这个订单不是新的，而是被refresh或者modificate了，所以用freshFresh evidence has emerged that casts doubts on the men's conviction.这里我认为可以通用，你说new evidence也绝对不算错的There has been fresh fighting between police and demonstrators. 新的战斗这里也是，实际上两者间的矛盾已经存在了，这里的fighting是主观上的“新”They decided to move abroad and make a fresh startmake a fresh/new start通用，均为重新开始，重新启动的意思其实两个词在很多地方都可以通用，英语语感还是很重要的，多听多看
