选as a result of,它是一个介词短语,意为"由于...",后面接名词或名词性短语
as a result 是一个插入语,意为"结果是...",一般要放在结果之前,例如：Today is a rainy day, as a result, I can't go out. 而用as a result of 就必须说：I can't go out today as a result of rain.
result in sth.意为"导致...",用在原因之后,结果之前,例如：The traffic jam resulted in his being late for class.
result to 和 result in 相反,用法是：结果+result to+原因,意为"起因于...",这比较少见,一般用result from 表示这个意思
