32、themselves.仅仅提高20%的产量，就意味着会让很多人远离疾病，拥有健康，让许多家庭不再忍受饥饿的折磨，能够自力更生。本句是一个简单句，现在分词短语going hungry和providing for themselves均作定语修饰其前的名词families。英语中现在分词和动名词都可以用作定语，但现在分词作定语时，是它所修饰的名词所发出的动作，和此名词之间在逻辑上是主谓关系，相当于一个定语从句；而动名词作定语时，是用来说明其所修饰的名词的功能、性质、作用等，相当于一个“for”短语。如：(1)a swimming fisha fish which is swimming(现在分词)

33、一条游泳的鱼a swimming poola pool for swimming(动名词)一个游泳池(2)a walking mana man who is walking(现在分词)一个正在行走的人a walking sticka stick for walking(动名词)一根拐杖(3)a sleeping cata cat which is sleeping(现在分词)一只睡觉的猫a sleeping cara car for sleeping(动名词)一节卧车车厢(4)a writing girla girl who is writing(现在分词)一个在写字的女孩some writi
