如何理解how to keep healthy句式
好像没有谓语呀。不是要翻译。句子不是要有主语和谓语宾语才完整吗？这是个句子吗？如是为什么能独立成句？

how to keep healthy 是不定式短语
who what which where whether how 后接不定式构成不定式短语
像 I ask Professional Xu how to learn english well.此时 how to learn english well 在句子中做直接宾语
做个比较吧容易理解些 want to do sth.how to do sth.前面那个我们知道是短语那how to do sth.句式是不是很相近呢
