упр.81
on Monday we had five lessons. The first was Russian. At lesson we wrote a dictation and did some excercises. Nick went to the blackboard. He answered well and got five. Pete didonot get five because he did not know his lesson. After the second lesson i went to canteen. I ate sandwich and drank a cup of tea. I did not drink milk. After school did not go home at once. I went to the library and took a book. Then i went home.
