The sentences don't have any "error" per se, except "in rainy days" (should be "on").
But that doesn't mean they read very well - I find many parts unnatural and strange sounding.
(like the vague "some" being overused, the expression "do some sports", etc)
Also the last two sentences can be structured better than tying sub-clauses with "and", I think.
But it is more a style and clarity issues than outright "problems".
