Ask Dr. Emily for Advice on Your Problem

Dear Dr. Emily,
I started Grade 7 this year and we have this project in our school: everyone in Grade 7 gets a little partner（伙伴）. It means that we each have a partner from Grade 1. We need to take them to school and help them know more about the school. I ‘m OK with children but I just can't make friends with them. All my classmates do better than me. I have a bad temper and I don't want to scare them away. I need some advice.
Kirsty,12

Dear Kirsty,
I think what your school does is a great way to learn how to take care of others. First, remember that the children from Grade 1 are much younger than you. They don't know as much as you. Second, remember not to be angry when things go wrong. You may scare them. Last but not least, keep in mind that kids love to try new things. So try to teach them something new and they can be interested in it. For example, you can play new interesting games with them. I hope things will be better for you soon.
Emily
