 ♣ healthy, healthful
　这两个词的共同意思是“健康的”。其区别是：healthy着重指身心处于良好的状态，用作表语或定语都可以；healthful是有益于身体的意思，多半用来修饰气候方面的情况，而以用作定语为多。例如：
　We have a healthful climate here.　我们这儿气候宜人。
 ♣ healthy, fit, well
　这三个词都可以表示“身体健康”。其区别是：healthy侧重有益于健康的条件或者是健康人的外部征象；fit指人的身体状况良好，尤其是指因经常锻炼而显得健康；well一般指人在特定场合下身体良好，常用来回答有关健康的询问。例如：
　He stays so fit because he often goes to keep-fit classes.　他之所以能保持健康是因为他经常去上健身课。
　I think I'll go to bed. I don't feel well at all.　我要睡觉去了，我感到很不舒服。
