(Present perfect tense is used to show that the action of not doing the homework is still relevant in the present.) 4. I haven't tried this famous cake. To be honest, it looks awful. (Present perfect tense is used to indicate that the action of not trying the cake is still valid, and the speaker's opinion about the cake is expressed in the present.) 5. Sorry, I have already seen "Blood Diamond." (Present perfect tense is used to communicate that the speaker has seen the movie in the past and it is still relevant in the present.)
