judy: how long have you been in canada? claude: i have been studying here for more than three years.

i am sitting in the park and writing my notes at the moment. it is hot. i hate this hot weather. i don't want to sit here. but roger is playing tennis with his friend. they are running and laughing. they need neither ice cream nor cold lemonade. they are having fun. they like this weather.

  oh, i see an ice cream man! it's great. ice cream is cold and tastes good. now i am happy too.

the positive character/hero

the positive character (hero) is always good, because he's always a positive role model for young children. especially in russian literature, the positive character (hero) always sets the examples for reader's behavior. the good always wins over bad (evil).
