1. 意思不同。 as a result of：adv. 因此，由于；作为…的结果。 result from：起因于；由……造成。
2.词组性质不同。 as a result of是由介词as加宾语构成的介词短语。 result from是由动词result加介词构成的动词短语。
3. 用法不同。 as a result of在句子里通常做状语。 result from是动词短语，在句子里可以做谓语、定语、表语、状语。 例如： As a result of evolution, it seems to me that humans should have no more valuethan any other creature. 由于进化的结果，在我看来，人类并不比其它动物拥有更多的价值。 As a result of his historic flight he became an international hero and legend. 由于他这次历史性的飞行，他成为了一个国际英雄和传奇。 Instead, many deaths and injuries in earthquakes result from falling objects and the collapse of buildings, bridges, and other structures. （做谓语） 反而, 许多死亡和伤害在地震起因于下落的对象和大厦、桥梁, 和其它结构的崩溃。 Any damage resulting from negligence is not to be compensated. （定语） 由于疏忽大意所造成的损害概不赔偿。 The deaths are resulting from hunger, sickness and weather disasters attributed to climate changes. （表语） 这些死亡是由全球气候变暖导致的饥饿，疾病及气侯灾难引起的。 Another possibility, depending on the initial conditions, is that the Universe could have undergone a bounce, resulting from the collapse of a previous Universe. （状语） 另一种可能是，宇宙可能曾经经历过一次由上一个宇宙塌缩而造成的跃变，具体情况取决于宇宙的初始条件。
as a result of 和 result from的区别：
它们的区别在于前者是介词词组，后者是动词词组。语义表达没有差别。
介词词组 as a result of 只是一个句子成分，其逻辑主语（即“结果”）用在 result from 中就是这个动词词组的主语，加上 from 后面的内容（即“导因”）后就可以构成一个完整的句子。而这个导因也正是 as a result of 的介词宾语。比较：
She is admitted to the university as a result of being an honored member of a prestigious society.
结果：She is admitted to the university
导因：being an honored member of a prestigious society
Her admission to the university results from her being an honored member of a prestigious society.
注意：由于这两个词组的词性和语法功能不一样，它们在句子中需要有相应的变化或添加某些词，以保证语义表达流畅和语法规范。
