比如这两句话:
He is smart and so he gets the first prize.
He is smart, so he gets the first prize.
我记得ron说过and so这种表达也是可以的,那么这两种因果关系的表达方式有什么区别吗?
另:
he worked out the most difficult problems, thus getting the first prize.
he worked out the most difficult problems, thus he got the first prize.
这两者所表达的因果关系有区别吗?
