Be动词的使用.If the big party weren't much fun anymore, everyone might go home.这句用weren't much fun anymore, 为什么不用wasn't fun anymore, big party 不属于第三人称吗?

问题描述:

Be动词的使用.
If the big party weren't much fun anymore, everyone might go home.

这句用weren't much fun anymore, 为什么不用wasn't fun anymore, big party 不属于第三人称吗?

这个是虚拟语气。
比如:
If I were you, I would check the dictionary.要是我是你的话,我会查字典。(我不可能是你,所以这里用的是虚拟语气)

  此处是虚拟语气,表示对来现在 big party 的一种假设,也就是说,此刻 the big part is much fun,每个人都在此玩儿的很愉快,但是“假如这次盛大聚会不会再有什么意思的话,那么每个人都会回家的”.
  对现在的虚拟,主句中的谓语动词用“would + 动词原形”,if 从句用过去时态,动词 be 按要求应该用 were,口语中也有用 was 的.
