根据第六段Until now, Boris has posted more than 40 Chinese culture vlogs online. But making these vlogs is not easy. Take reading the poem "Second Farewell to Cambridge" by Xu Zhimo as an example . （到目前为止，鲍里斯已经在网上发布了40多个中国文化视频博客。但制作这些视频博客并不容易。以读徐志摩的诗《再别康桥》为例。）
以及第七段"I can understand and read every word in the poem, " Boris said. "But to touch readers, I need to use proper feelings while reading." So he needed to look for much background information and make his feelings suit each part of the poem. (鲍里斯说: “我能理解并读懂诗中的每一个字。”“但为了打动读者，我需要在阅读时使用恰当的情感。”因此，他需要寻找大量背景信息，使自己的情感适合诗歌的每一部分。)可知，诗《再别康桥》被提到目的是展示Boris在vlog制作方面的努力。故选C。
