检查英语文章语病 这是课堂小演讲请大神修改
Today I’m glad to make aspeech here.Then I will tell a joke to you.
A school teacher was telling her students theimportance of making others happy.Now,she asked all children,“Has anyone ofyou ever made someone else glad?”
A small boy reply immediately,“I've made someone glad yesterday.”
“Well done.Who was that?” the teacher washappy.
“My grandma.”
“Good boy.Now tell us how you made your grandmother glad.” The teacher said.
I went to see her yesterday,and stayed with her three hours.Then I said toher,‘Grandma,I'm going home,’ and she said,‘Well,I'm glad’!
My question is ,was thestudent’s grandma glad in fact?
