Examples
- I have always thought he is/was a good guy.
- I have always thought a boat doesn't/didn't float.
- I have always thought the sun rises/rose in the east.
What are the DIFFERENCES? Is there an absolutely correct tense I should use? To non-native English speakers, they will think "have always thought" is PRESENT perfect tense. It started in the past, and it's continuing to the PRESENT. Therefore, I should use "is/ doesn't/rises for example 1./2./3." Howevere, I asked some native English speakers. They say "was/didn't for example 1./2." is correct. For example 3, they say "rises and rose" both are correct. Why does this happen?
What does "I have always thought he IS a good guy." and "I have always thought he WAS a good guy." mean to you? Do they mean the same thing?
