Past 和 passed 的读音完全一样。区别在于你需要的是不是一个动词。

简短回答 #

  • Passed 是动词,是 pass 的过去式:She passed the exam.
  • Past 负责其他所有情况:作名词、形容词、介词或副词,表示时间或位置。in the past、walk past the store

passed = “经过、通过”这个动作 #

  • I passed my driving test.(我通过了驾照考试。)
  • A car passed us on the highway.(一辆车在高速上超过了我们。)
  • Time passed quickly.(时间过得很快。)
  • He passed the salt.(他把盐递了过来。)

past = 时间或位置 #

  • In the past, I wrote everything by hand.(名词)
  • The past week was busy.(形容词)
  • It's ten past five.(介词)
  • We drove past your house.(介词)
  • A bus just went past.(副词)

测试方法 #

试着把句子改成现在时。

  • 如果这个词变成了 pass 或 passes,就用 passed。
  • 如果它不变,就用 past。

We walked ___ the park. → “We walk past the park.”(不变)→ past

Three hours ___. → “Three hours pass.” → passed
