急急~~ 有英文唔識

已經係過去式

仲點改？

Your passage is already in past tense. However, I advice you change the 'First' in the second sentence into 'Firstly' and also 'shopped around the mall' add 'in' before 'the mall'

I went to the Festival Walk with my mother this morning. We watched a movie in the mall and had a lunch in Yoshinoya. In the afternoon, we shopped aournd the mall and bought something. Then we went to the Spagetti House for dinner.

To keep the orginal and correct the grammer and tense, you need "the" before a place, e.g. a restaurant.

In the morning, I went to the Festival Walk with my mother. Firstly, we went to a cinema to watch a movie, then we went to the Yoshinoya to have lunch.
In the afternoon, we shopped around the mall and bought something, then we went to the Spagetti House to have dinner.

To improve the writing, you may consider the following:

I went to the Festival Walk with my mother in the morning. We watched a movie in a cinema and had our lunch at the Yoshinoya. We shopped around at the mall in the afternoon and had dinner at the Spagetti House.

"shopped" means "watched and bought"
if "window-shopped" then means "watched but did not buy"

Hope this is useful

如果咁改可唔可以?

In the morning, I went to Festival Walk with my mother. First, we went to a cinema and watched a movie, then we had lunch in Yoshinoya.
In the afternoon, we shopped around the mail and bought something, then we went to Spagetti House and we had a dinner.

因為本身都已經係past tense, 唯有把 'to' 唔要. 再改後面的動詞.
