Ответ:

Все очень просто

Yesterday my sister felt sick, she feel good. 2 We met Susan yesterday, we meet Helen. 3 At the lesson we read an English book, but we read a Russian book. 4 The road led to the theater, it lead to the museum. 5 The children slept in the afternoon and they sleep at night. 6 My boss left in the afternoon, he leave in the morning. 7 We kept no secrets, we keep any secret at all. 8 Loran dreamt about a new bag, she dream about new shoes. 9 The children fed a cat, they feed dog. 10 My granny swept the floor, my mother sweep it.

1 Yesterday my sister felt sick, did not feel  good. 2 We met Susan yesterday, we did not meet Helen. 3 At the lesson we read an English book, but we forgot about a Russian book. 4 The road led to the theater, it  was closed to the museum. 5 The children slept in the afternoon and they did not sleep at night. 6 My boss left in the afternoon, he worked hardly  in the morning. 7 We kept no secrets, we  did not keep  any secret at all. 8 Loran dreamt about a new bag, she did not think  about new shoes. 9 The children fed a cat, they  did not find a dog. 10 My granny swept the floor, my mother  washed it.
