Notes:
crab:蟹
*********************
I was a volunteer at an environmental day camp for children on Saturday. The weather was beautiful. It was sunny, and there was hardly any wind. In the morning we went down to the river to look at crabs and other kinds of living creatures. The temperature got up to 18 degrees, and the crabs were moving around in the warm sun. We caught 5 different kinds. These crabs stay underground when it gets cold, so this was our last chance to see them this year. (by Prof. Douglas Jarrell)
