建议把难度稍微提高一下,意思相同的次可以替换,修改句子结构而不改变句意,并加一个结尾：
Hello,ladies and gentlemen.My name is Elijah.I am a 13-year-old gentle boy,because my classmates always say"Oh,you are really gentle."But in fact they say"Oh,I cannot bear you,you are so boring!"And I do not know why.So today I will talk about my character.
I am sweet-tempered most of the time,for example,if you lend your classmates a pen.Then he or she broke it.Maybe you will let him or her buy a new one or give you the money.But I will not do that.Usually I will forgive him or her.Although I can bear this kind of things,I never forgive someone whose broke the most important things of mine.
Sometimes I am humorous.About three mouths ago,I told my friend something crazy about Equivalent substitution “The customer is God,God is a girl,so the customer is a girl.”After I told him,he laughed all day.And by the way,my math is really nice.
