Question

急！求大神解答英语句子！！感谢！！

Distance learned can also adjust the pace of a course to their needs,including when to complete the assignments or even when to submit the answers to best questions.求解答'''这个句子中，逗号后面是做什么语法成分？非限制定语省略which is 还是分词作状语？including后面为什么可以加疑问词+不定式的形式？求详解，谢谢！！！！

Answer 1

逗号后的部分是插入语，充当定语，修饰needs, 或者相当于省略形式的非限制性定语从句，(which are ) including when... or even when ...
including 是现在分词，可以接宾语，疑问词when做宾语，后面的不定式做定语修饰when

　　逗号后面是这个分词形式的介词（也可以看作include的现在分词）知道句尾的介词短语（或现在分词短语）作状语，而when to complete the assignments 和when to submit the answers to best questions.是两个用or并列起来的带有特殊疑问词的动词不定式结构作介词（或现在分词）的宾语。
