That we now have an abundance of the proof that was called for was established when Barbare Bentley reviewed the relevant evidence in 1977, and since than many more observations and experiments have provided still further proof that ants benefit plants.
请问这句话的前半句该怎么理解？谢谢！
句子的主干是That was established。这句话的杀伤力在于句首出现主语从句，其中又嵌套了一个定语从句"was called for"修饰proof。不过只要把握住句子的主干“什么什么是确定的了”这句话也不难。
