Question

water to drink中to的用法是什么?是类似目的状语什么的吗?

Answer 1

这个to是动词不定式符号.当想表达一次性具体性将要发生性行为动作时,常用to do这种结构,可做
主语To play with fire is dangerous.
宾语I like to smoke.
表语My job is to teach you English.
定语I need some water to drink.
目的状语Let's stop to have a rest.
结果状语He worked hard to pass the exam.
原因状语I'm sorry to keep you waiting .等.
当然,更重要的是合成谓语啦be to do,be going to do,have to do,used to do,ought to do.
