Pores allow liquid, especially sweat,(pass) through. By (sweat), our bodies keep up a normal temperature. When it is very hot, we sweat a lot, but(strange) enough, when it is quite cool, we also sweat. On a cool day, our bodies produce average of 700 ml of sweat. That is(much) than 0.5 kilos. 答案：【1】informed【2】whether【3】it【4】is made【5】protection【6】to pass【7】sweating【8】strangely【9】an【10】more
