2. We form the present perfect using the auxiliary verb have/has + the past participle of the lexical verb
Examples: I have bought a new phone, She has walked to school, He has driven a new car, They have eaten at a Sushi restaurant

3. Be careful as the third person singular in the abbreviated form He/she/it’s (worked) is the same as in the simple present He/she/it’s (ugly). The context will help to understand
Been to: I have been to China, Have you ever been to Australia? It is the first time I have been to that restaurant
Been to v gone to:
I have been to the US (I went to the US and came back)
I have gone to the US (I’m still there)
