Simonehow can I 和 how to 的区别。在 can you tell me.
的有关信息介绍如下：
How can I是特殊疑问句，可以独立成句。如：How can I turn on the heating?How can I make a shadow?how to是“疑问词加动词不定式”结构，一般不能独立成句，只能作为句子中的一个成分。用在这一结构里的疑问词有who、whom、what、which、whose、when、where、how和whether，但不能用if，如：How to fight pollution remains a problem.I don't know whether to refuse it or not.Who to bell the cat is a big problem.Who to take care of my grandmother would be a problem.I don't know how to operate the machine.
