求be going to结构的英语短文一篇！！急急

l am going to have a picnic.So,l go to the supermarket with my parents.We buy a lot of thing.Juice,chips,bananas and so on.My friend Betty will go with me.We are going to have a good time.(我自己写的给点鼓励，预初的！)

你也可以这样:用现在进行时表将来,这是口语用常用的.
I am leaving for school.
I am heading for school.
I am going to school.(一般不说I am going to go to school.英语口语中没有这种说法.)
当然用将来时也行:
I will go to school.
