一个句子成分不太懂Thus some people see him as what might be called an

　　what might be called an unreachable benchmark 这个从句做as这个介词的宾语,故这个是what引导的宾语从句,只不过这个句子是做介词的宾语的.
　　宾语从句中做介词的宾语时,一般用“wh-words”（如what how whether等）来引导.
　　或者用that引导,但前面要加形式宾语it.如Thus some people see him as it that might be called an unreachable benchmark.
　　欢迎采纳!谢谢!
