区分so、therefore、as a result、as a result of？要调理清晰。
so与therefore：意为（因为。。。）所以，因此，只要记住therefore是插入语就OK了.e.g.He doesn't feel well,so he can't go to school today=He doesn't feel well,therefore,he can't go to school today.
as a result as a result 单独使用，放句首后面一般用逗号隔开，并且不能连结2个句子,作为一个最终结果的意思.
e.g. He worked hard at his study.As a result, he passed the exam easily. He defeated all competitors and won the scholarship as a result. as a result of 由于的意思,后面不可以接从句，常接名词或代词，e.g.He was late as a result of the snow.
