小学英语作文去购物

Last sunday, my mom asked me to the shop with her , because we were out of salt.

My mom took me to the salt sector directly and she chose the salt she wanted in no more than 10 minutes.我妈带着我直奔卖盐专区，并且在10分钟内就选好了要买的盐。
Then she went to pay the cashier .然后我妈就去收银台付款了
when she was in the line , I saw a box of chocolate..在她排队的时候我看中了一盒巧克力。
I wanted to buy it very much , so I took it to my mom .我很想买这盒巧克力，所以我就拿去给我妈付款。
Luckily, she bought it for me without any complaints . 幸好啊，她二话没说就帮我买了。
I thought she would buy the chocolate for me was just because I had get a good place in my last exam . 我想，她愿意帮我买巧克力完全是因为上次考试我考的很好。
So I will work harder on my study so that my mom will buy all that I want when we go to the shop together next time. 所以，我就想啊，我一定要更努力地学习，那么下次我和我妈再去商店买东西的时候，我想要什么她都会帮我买了。
