It is very lucky for me to pass the test.But I am still happy that I passed it.Now I have more time doing something I love to do.I made a goal for myself.I hope I can achieve it before Septermber.
Yesterday my teacher asked me to make a PPT to introduce why my grade improved so quickly.When I was talking,i was very nervous because I hardly ever talk to so many people.Suddenly,I saw Tina was staring at me with a encouraged smile.I had confidence to myself.I finished the introdution and won a burst of applause.
After the talk,I thanked Tina and we became friends as well.
