Question

I could never forget how i learn to swim.one afternoon.i went to swimming pool with my father.这句

这句的病句在那里。该怎么改正

Answer 1

1.I could never forget how i learn to swim.
时态首先没有一致，主句是过去式，所以作为宾补的how i learn to swim应该用过去式：how i learnt（可以是learned） to swim

2..one afternoon.i went to swimming pool with my father.
这句句子大问题没有，小问题有两个。one afternoon做状语而不是独立的句子，所以后面是逗号而不是句号。游泳池应该是有特指的，就是第一次学游泳的那个游泳池，所以加个the

连起来，就是：I could never forget how I learnt to swim.One afternoon,I went to the swimming pool with my father

有不懂的可以再问~~希望能给你带来帮助~~
