这是2021年新高考考试全国卷2阅读理解D的一个句子。前面一个网友问了 failed 的使用方法。但我感觉这里还有一个使用方法比较奇怪，那就是 with a man on ahorse，这是 with 复合结构吧，它可以用作表语吗？求专家剖析指点，谢谢！
附全段材料作参考：
For Texas cattleman Pete Bonds, it’s increasingly difficult to findworkers interested in watching cattle. But Bonds doesn’t believe a robot isright for the job. Years of experience in the industry—and failed attempts touse technology—have convinced him that the best way to check cattle is with aman on a horse. Bonds, who bought his first cattle almost 50 years ago, stillhas each of his cowboys inspect 300 or 400 cattle daily and look for signs thatan animal is getting sick.

这个with a man on a horse 应该不是with复合结构，而是普通的介词短语，on a horse是定语，修饰a man， 即骑马的人。句子上下文逻辑告诉大家，赶牛群的最好的办法就是用骑马的人，而不是用机器人或其他高科技技术。
with复合结构其实就是介词with后接了复合宾语，本质上仍然是一个介词短语，而介词短语可以作状语、定语和表语，所以with复合结构也应该可以作表语的，虽然相对较为少见。比如下面COCA例句就是with复合结构作表语：
The only way I actually like to drink it is with lemons added!
