there were not anything in sight中为什么用were而不是was?anything不是单数

There were not anything in sight. were 还是was? why 为什么是There were not any in sight而不是there was not any in sight 请问there were no any in sight,而不是there was no any in sight there were no more mountains in sight.为什么用were 不用was there were not any in sight there were no more mountains in sight 我想不通为什么用no 不能用not there was no more buses这句话中为什么是was而不是were 为什么是用were而不是was? He didn't find anything in the bushes的同义句和They were not afra 为什么是 anything important 而不是 important anything Were you a pianist?Yes,I was.为什么问要用were?不是单数应该用was吗?为什么答的又用回 If I were you 中为什么是were而不是am或was
