The molecular approach to detecting peptide hormones using cdna probes should
also be much faster than the immunological method because it can take years
of tedious purifications to isolate peptide hormones and then develop
antiserums to them
整句话大概可以简化成
The molecular approach should also be much faster than the immunological
method because it XXXXX
看原句because后面的it是指immunological method
但这个it不是应该指the molecular approach吗?
想问一下because 后面接的代名词应该是指前面主句的主词吧?!
谢谢!!
