A Great day I am so happy today since I finally finish my hard math reading tasks and can start to talk with my professor about how to write my dessertation. I am a little bit nervous about it because I never learn how to write a dessertation but I believe I can beat it anyway. Furthermore，I learned 5 new meals from my mom and I can take care of my little brother without doubt. Thanks to the great world and I will pay more attention to my family，my body and find the opportunity to improve myself and help others forever.
