Tim plays ( )nfootball on Saturday.He plays ( ) the piano on Sundays.

问题描述:

Tim plays ( )nfootball on Saturday.He plays ( ) the piano on Sundays.
一不小心多打了一个N.问题是填入合适的单词。

改为否定句吗?
Tim doesn't play football on Saturday.
He doesn't play the piano on Sundays.问题是填入适当的单词,每线一词。两句都很完整, 不缺任何单词了。额,好吧,或许是题目的问题,谢谢!
