The past form of the modal verb "should" is "should have." It is used to express an obligation or expectation that was not fulfilled in the past.
For example, "I should have studied harder for the test" implies that the speaker had an obligation or expectation to study hard, but did not fulfill it. Similarly, "She should have arrived by now" implies that the speaker expected the person to arrive at a certain time, but they have not yet arrived.
In both of these examples, the use of "should have" indicates that the speaker regrets not fulfilling their obligation or expectation. It can also be used to express a sense of missed opportunity, as in "We should have taken that job offer."
The past form of "should" can also be used to give advice or make recommendations about something that has already happened. For example, "You should have called the police when you saw the suspicious activity" advises the listener to take a certain action in hindsight.
Overall, the past form of "should" is a useful tool for expressing obligations, expectations, and regrets about the past, as well as for giving advice about past events.
