I have some problems to understand the true usage of “would” and “would have pp”. I have already reviewed many forums and websites, but I have not managed to come to any conclusion. For instance, in these sentences:
1- People in the area had never seen this phenomenon before, but they also reported that there less mosquitoes than they would have expected, given the amount of standing water. Why “would have expected”? And to be precise: Why not “would expect”?
2- Another reason to use a hybrid format is when you want to highlight skills and achievements from earlier in your career that would otherwise be buried at the bottom of the second page of your resume Why “would be buried”? And to be precise: Why not “would have been buried”?
3- Without SuperM, I would never have trusted my memory to keep a word for 10 days. Why “would never trusted”? And to be precise: Why not “would never trust”?
4- People in the area had never seen this phenomenon before, but they also reported that there less mosquitoes than they would have expected, given the amount of standing water. Why “would have expected”? And to be precise: Why not “would expect”?
5- My life would have been completely empty without you. Assuming ‘without you=if you were not in my life”, is this sentence correct as well: My life would be completely empty without you (if you were not in my life)
Please forgive me if my question is a bit basic.
