я напишу открытку другу из египта. нигде в интернете нет такого письма. моя учительница его проверила, так что без ошибок.

hi, dasha

i'm writing from egypt. i'm staying in the hotel "cleopatra" in cairo. it is very interesting here. i'm itching to tell you about everything!

it's very hot here. i'm spend a tot of time on the beach. i met iren and george here whom we met in england. they send you greetings. on the beach we play volleyball and water polo. my friends and i are doing scuba diving and we are engaged in surfing. it's amazing! yesterday i saw the piramids. dusty tombs, magnificent   temples, treasuries, mysterious mumies shocked me! i learnt many interesting things in the history or egypt. 

i bought some souvenirs, took many pictures to show you. i'm having a good time! it's a pity that you couldn't do with me. take care.

love,

kotik
