     Hi! My name is Jackson. I'd like to share my New Year's plans with you. If you have better ones,

please send them to me.

     ● Keep good habits. This includes brushing my teeth after meals, washing my hands after going to

the bathroom, and covering my nose and mouth when I cough. Also, I will put my dirty clothes into the

washing machine, not on the floor in my bedroom.

     ● Keep healthy. I will eat more fruit and vegetables every day. As the old saying goes, "An apple a

day keeps the doctor away." I will also drink more water and milk instead of soft drinks.

     ● Be helpful. I will help people who need my help. And I plan to give away my old clothes and toys

to kids in poor areas.

    ● Be polite to others. I will remember my "please", "thank you" and "excuse me". I will never say

curse words (脏话).

    ● Work hard at my studies. I will finish my homework on time. If I have any questions about my

lessons, I will ask my teachers actively.
