凭借用英语可以说是"by virtue of"或者"through". 来源方面，"by virtue of"是由拉丁语"virtus"（美德，能力）衍生而来，"through"则源于古英语"þurh"（通过）。

例句：

1. By virtue of his hard work and determination, he was able to achieve his goals.

（凭借他的努力工作和决心，他能够实现他的目标。）

2. She was able to enter the competition through her connections.

（她能够通过自己的人脉进入比赛。）
