分析下这句英语句子结构Some teachers are concerned about this trend ,arguing that the heavy investment that students are unite to make in computer and communications equipment contradicts of "open".请彻底分析下句子成份,其中 are unite to make in 是什么成分?Students are unite to make in heavy investment in computer and communications equipment.中are 是谓语那 unite to make in 是什么成分呢？能不能分析一下？

应该是united 吧？students are united to make 作谓语,in computer and communications equipment contradicts of "open"意思是在电脑和开放的交流设备方面。

首先翻译一下：一些老师（很）关心（关注）并且争论（议论）这种趋势：学生们被联合起来做出的非公开的在电脑、通讯设施方面的巨大投入。
Some teachers this trend这句就不用讲了，arguing that the heavy investment that students are unite to make in computer and communications equipment contradicts of "open".在这句里，that 。。。是和are concerned about。。。平行的，也就是arguing 也是Some teachers 的谓语，arguing 后面接了一个宾语从句，也就是that the heavy investment that students are unite to make in computer and communications equipment contradicts of "open这个宾语从句表示的就是this trend 。并且，从句里又有从句：the heavy investment that 。。。that 连接了一个定语从句：students are united to make the heavy investment in computer and communications equipment（原句），最后， the heavy investment that students are unite to make in computer and communications equipment作为一个整体作为了主语，后面就不用讲了撒，这后半句的主干就是the heavy investment contradicts of "open".

分句可以分为3句Some teachers are concerned about this trend.They are arguing that the heavy investment contradicts of "open".Students are unite to make heavy investment in computer and communications ...
