原问题：Making it easy to see arts students knowing nothing about physics.为何用knowing动名词做宾语从句谓语后面还跟着while science students suffering a lot in their thesis.的从句,这是状语从句,为何用suffering动名词做谓语?
回答如下：
Making it easy to see ( arts students knowing nothing about physics ) (while science students suffering a lot in their thesis ).
1.see 是个及物动词.后面可以接一个名词.也可以接一个从句.第一个小括号内的 knowning 是动词的-ing形式,在这里可以叫做动名词.动名词的语法功能相当一个名词用,用作 see 的宾语.但是这个动名词自己还带有一个逻辑主语 “arts students”,所以它在语法上叫做“动名词的独立主格结构”.这时的 knowning 不能叫做谓语.即：第一个小括号整体看作成一个名词.
这个独立主格可以改写为一个宾语从句：...see that arts students are knowing nothing about physics.这时的 knowning 才可以叫做谓语.
2.第二个括号是 while + doing 结构,它也是动词的-ing形式（非谓语动词）常见的一种用法.它也和上面的句子一样,自己也带了一个逻辑主语“science students”,在这种情况下,suffering 不能称为谓语.
它也可以改写为一句话：...while science students are suffering a lot in their thesis.
以上两种情况都是高中英语的重点,都是要做大量的讲解和练习的.语法归类属于“非谓语动词”.
