Question

这段英文有问题没有?如果有请指出错误的地方.
thorough investigation is made on the experimental teaching conditions of these schools through investigation,analyzing the datum

Answer 1

be made on 没有这个用法也.
而且最后through 后面要么全接动名词 through investigation and analysis of the datum,要么全接现在分词through investigating and anlyzing the datum .
如果lz是想analyzing the datum 分句的话,那么逻辑主语是thorough investigation,这也是不可以的.
最好吧汉语原句给出来,这个句子很混乱.
