In this ease, the verb-form depends on its own meaning. Look at the examples on the screen

Is that so?Ss: Yes.T: And the verb-forms after as if or as though is the same as the verb-forms after wish. Look at the examples on the screen.1. Ive loved you as if you were my daughter.2. They talked as if they had been friends for years.3. It seems as if it would rain.(Teacher and the students go through the examples together to make sure the students understand them
