这一句英语对不对?50分!做散分童子了!

最后句有问题 which要去掉．could最好变can.我们发现我们巨大的财政浪费可以从以下两个方面被精简．就是we learned that our colossal waste of financial resource can be boiled down to 2 following parts.前面2句都没有问题．

不对!
第二句中的主句部分中的宾语从句不完整
也就是we learned that our colossal waste of financial resource which could be boiled down to 2 following parts

learn后的宾语从句中只有主语,和一个主语从句,缺谓语和宾语

raked->ranked?

Although the company has raked up in recent years, we just slightly meet the turnover. And from the survey we carried out 3 months ago, we learned that our waste of financial resource was great, which can be boiled down to following two parts
个人感觉句子有些措辞不是那么恰当。。。

Although the company has recovered financially in recent years, we only manage to meet the turnover slightly. According to a survey that we carried out 3 months ago, our colossal waste of financial resource could be boiled down to two parts. They are XXX and XXX.
