there were no more mountains in sight.为什么用were 不用was

there were no more mountains in sight.为什么用were 不用was there were no more mountains in sight 我想不通为什么用no 不能用not 请问there were no any in sight,而不是there was no any in sight 为什么是There were not any in sight而不是there was not any in sight There were not anything in sight. were 还是was? why No buses_____that steet and there were no taxis in sight There was no parks near my home.为什么要用was,不用were there was no more buses这句话中为什么是was而不是were If there was no air, people would die.为什么不用were there were not any in sight 英语翻译那为什么用were不用was? 根据there was no one in the park.there were no people 还是 there
