自信心

过去情态动词：should have、could have、would have

谈论自信时，你常会回顾过去的行为，并以现在的角度重新审视它们。

Should have + 过去分词（责备或遗憾）

表示当时本来应该做的事：

• I should have spoken up in the meeting. → 我本应在会议上发言。
• She shouldn't have doubted herself. → 她本不该怀疑自己。

Could have + 过去分词（未实现的可能性）

表示当时本来可以做、但没有做的事：

• I could have applied for that job. → 我本可以申请那份工作。
• We could have achieved more with a different mindset. → 如果有不同的思维方式，我们本可以取得更多成就。

Would have + 过去分词（假设的结果）

表示在其他情况下本会发生的事：

• I would have been more assertive if I had believed in myself. → 如果我当时相信自己，我会更坚定自信。
• She would have overcome her fears if she had stepped out of her comfort zone. → 如果她走出舒适区，她本会克服恐惧。

发音： 在口语中，should have → should've（shou-deuv），could have → could've（cou-deuv）。不要把它们和常见错误 should of 混淆。
