Has Ann lost her passport? – Anna pasportini yo’qotdimi? (Natijada hozir unda pasport yo’qmi?)

   Life experience – Hayotiy tajriba bu nima degani : Biz hayotimizda bajargan narsalar haqida gapirsak Present Perfectni ishlatamiz. Unutmang muximi qachon bajarganmiz aytilmasligi kerak. Siz qachon bajarganizni aytizmi past simple ishlatiladi. Buyerda muximi biror kishi hayoti davomida shu ishni qilgan yoki qilmaganini aytish. Biz aytayotgan odam tirik bo’lshi kerak. Agar buvim Amerkada bo’lgan desangiz- buvingiz tirik bo’lshi kerak. Tirik bo’lmasa Past simple ishlatasiz.
