何时用was何时用were？

何时使用was与were 英语中，was和were均为be动词的过去式，二者的使用需根据主语的人称和数来判定，同时存在特殊语法规则的例外情况。 一、基本规则：根据主语人称和数选择 第一人称单数I和第三人称单数he/she/it后用was。

• I was at home yesterday.
• She was late for the meeting.
• The book was on the table. 第二人称单复数you、第一人称复数we和第三人称复数they后用were。
  • You were right about the answer.
  • We were in Paris last summer.
  • The children were playing in the park. 二、疑问句与否定句中的应用 疑问句中，was/were需置于主语之前；否定句中直接加not可缩写为wasn't/weren't，规则与句一致。
    • Was he absent from class?
    • Weren't they happy with the result? 三、特殊情况：虚拟语气中的were 在虚拟语气中，论主语是第几人称，均用were表示与事实相反的假设。
      • If I were you, I would take the job.实际我不是你
      • She talked as if she were the boss.实际她不是老板
      • I wish I were taller.实际身高法改变 四、固定搭配与倒装结构 部分固定表达或倒装句中，were可用于单数主语：
        • Were it not for the rain, we would have gone out.倒装虚拟语气
        • As it were, he became a legend in his lifetime.固定短语，意为“可以说” 五、主谓一致的例外 集合名词作主语时，若整体用was，个体用were：
          • The team was ready to win.整体
          • The team were arguing about the strategy.个体成员 通过以上规则可明确：was用于单数主语，were用于复数主语，而虚拟语气中统一用were，这一区分是掌握过去时be动词的核心。
