英语：这句话有没有错误呢?有更好的说法吗?

您所给的句子,语言表达的【内容层次】上,似乎不大合理,只需要简单调整一下就更好了——From these,I have enjoined great pleasure and gained a lot.or I have enjoined great pleasure and gained a lot from these.
原因：【享受到极大的乐趣并且有很多收获】,这更符合一般感受的层次和表达的内容关系.当然,必要的话,你还可以改变为——From these I experienced,I have enjoined great pleasure and gained a lot.
祝你开心如意!
