英语语法好的大神进来帮帮忙
This is especially ture when we consider the fact that the tuition and fee has been rising esch year,which means to many,pursuing higher education is very much like making a substantional investment 请帮我分析一下这句话中动名词的语法现象,为什么在这里会用到动名词,这里用动名词的意义
Thus,students and their parents alike tend to expect reasonable rates of return that can be,to some degree,quantifield by the job skills students possess.请帮我分析一下这句话里插入语的语法现象

Answer 1

这句话中的第一个动词ing形式has been rising不叫动名词,它是一个现在完成时的进行时态（have/has been doing）,这个时态表示动作从过去持续到现在并且还将继续持续下去.eg:i have been working for a whole day,but i still have a lot of work to do.第二个动词ing形式pursuing heger education 是一个真正的动名词,在这句话中作主语.eg:Looking after the little babies is my job.第三个动词ing形式 making a substantional investment 也不是一个动名词,它在句子中是like doing sth（喜欢做某事）的结构.另外动名词的作用相当于名词的作用,可以做主语,宾语,同位语等等.
to some degree是一个插入语,意思是“在某种程度上”,应该表示一种强调.
