大家帮我看看这篇英语作文有没有语法错误?
It was a sunny day today,when i got up in the morning,i decided to see my grandparents.so i took the bus and got there at noon,they were happy to see me,and i was very happy,too.
In the afternoon,my farther asked me to help him water the plant,and i was happy to see the flowers smiling in the wind.
In a word,today is a unforgetive day.because i saw my relatives and helped people.

答案

是孩子写的吧?总体来说挺不错,但是在初学阶段,最好避免用and i was happy to see the flowers smiling in the wind.这种从句,要把句子分开,说明白,可以说In the afternoon,my father asked me to help him water the plant.I finished the work and felt very happy,the flowers are smiling in the wind beautifully.
另外,最后一句应该用was而不是is.还有,unforgetive不好,可以换成外国人更加常用的amazing
