Tolong dong kasih contoh tentang giling opinion dan asking opinion

aku kasih contoh kalimat nya aja ya......

asking someone's attention : "excuse me, do you have some time to talk?"

checking someone's understanding : "do you understand? if not i can tell you again.." atau "do you get it?"

showing appreciation : "thank you, i really appreciate it"

giving opinion : "well, i think *opinion*"
