1  ' After climbing the mountain Tai（Mount. Tai） people( who )这里没有必要用定语从句，后面是谓语和宾语的成分 do not want to climb the mountain.'
2  Although we were tired,we played very happy.
玩得开心，一定要用play吗？这样表达很Chinglish. Although we were tired,we had a lot of fun.而且修饰动词要用副词happily.
3.We had a plentiful of food to supply energy.    plentiful在这里不能这样用，改成plenty.此外，补充能量 用refill就可以了，比较地道。
