Grammar

 After I learn 12 rules today, I finally understand how to use non "s" and use plus "s" in my sentences. Actually, I don't know how to use grammar properly when I was in secondary school. Since my grammar is so bad, these rules really help me to improve my writing. Now I just have to read and write a lot. So as a student, I will use these 12 rules wisely.

 Last but not least, thanks to our madam because teaching us to use these rules properly. 👍🏻
