Answer 2

in first line on the place of 'wa 'there should be was (spelling error).followed by walk there should be 'on' in the place 'over'(preposition error)
in the second line on the place of knew there should be know ( tense error).there should be like on the place of like (meaning mistake ).

.in fourth line on the place of 'as soon as' there must be 'as long as'(preposition error).

in the last line the word 'and' is unnecessary conjunction.
