3.“疑问词+不定式”可以放在动词后面作宾语，相当于宾语从句。

Do you know how to plant a tree ? = Do you know how we should plant a tree ? I don’t know what to do. = I don’t know _____ _____ _____ do. I don’t know how to do it. = I don’t know _____ _____ ______ do it.

【注意】what作do的宾语，所以不加it，即“做什么”。how 不能作do的宾语，不能说“如何去

做”，应该说“如何去做某事”才完整，所以do后加宾语，如：how to do it / the work.
