1. When I was young, I was not able to ski. After I took ski/skiing lessons for three months, I became a good skier. Now I am able to ski well.
(Will you check this passage? Are the sentences grammatical? Do we have to use 'ski lessons' or 'skiing lessons'?)
2. When I was young, I was not able to ride a bike. After I practiced riding a bike for one month, I became a good biker. Now I am able to ride a bike well.
(Would you check this short passage as well? Thank you.)
In #1, use 'skiing lessons'
#2 is fine.
