1) Usually,I'm go walking with my friends,so when I hear this word ,I imagine long streets,nice parks and me surrounded by friends.
2)Of course I like!My town is very big ,there are so much lakes ,parks and shops right here.
3)In my opinion,yes,because when you go in the streets ,you burn your calories and it makes your body fitter and stronger.
4)I'm not a big fan of walking ,so if my friends call me to walk somewhere,I usually say yes,but usually I stay at home .
5)When I'm walking I can do many useful things like feeding birds ,dogs or cats,plant a tree and etc.
6) I'm not pretty sure what my walk style is looks like,but I think my walk style is not so fast as my friends style.I prefer to walk slower than faster.
