关于not only,but also用法的问题.
（1）Not only is this young scientist intelling,but hardworking.不是说not only与but后所随成分应一致.这句明显不一致啊!
（2）not only…but also…与not only…but…as well的用法的区别并举例.
（3）Not only had the poor man been arrested,but he had been sent to prison as well.这是原句。
a.Not only had the poor man been arrested,but also he had been sent to prison.
b.Not only had the poor man been arrested,but he had also been sent to prison.哪句对。请说明理由。还有什么时候but also 要分开的？

Answer 1

第一句分类的是那个年轻的科学家的特点有两个,即不但聪明而且努力
第二个是没有区别的,比如说
he is not only a singer but also a writer.
he is not only a singer but a writer as well
第二句更强调后者一些
