i have my own room. i don't share it with my brother anymore.

my new room is large and light.i have a big bed in it ,a computer table and ,of course, a computer on it ,also there are book shelves ,wardrobe ,drawer,carpet and my favorite toys.

1. i exercise regularly in summer but more to do in winter. 2. she usually walks slowly but now she is walking even   faster . 3. nina speaks loudly but mary speaks even   louder . 4. he runs fast, than other boys. 5. i don’t sleep enough, less   than 8 hours. 6. he behaves badly, than other boys. 7. i smile often, more than my sister. 8. peter lives far from school, but ann lives closer .

я думаю, что  4 и в 6 предложениях ничего изменять не надо. может я ошибаюсь.
