August 16th,Sunday,Sunny

Hello! I'm Dudu. Today I climbed the mountain with my family. There are four of us:my dad,my mum,my brother and me. We started at 8 a.m.
My dad is the tallest in my family. He walked faster than the rest of us. My mum is thinner than my dad. At first, she walked slower than dad but faster than my brother and me. My brother is 10 years old. He is younger than me,and he is shorter than me too. But he ran very fast! He ran ahead(前面) of mum.

We helped each other on the way. When we felt tired,we cheered each other on. At 10 a.m. ,we got to the top. The mountain was so high! We saw many beautiful things. We were all tired but very happy. I learned that staying together and helping each other can make everything easy and fun. I love my family so much!
