几年前,我去药店买药。那时孩子才刚刚2岁多,因体质不好常常感冒。当我不知买什么药的时候,在一家医药超市里,一个年轻的工作人员向我了解孩子的情况 A few years ago, I went to a pharmacy to buy medicine. At that time, the child was just over two years old and often had a cold because of poor physical fitness. When I didn’t know what medicine to buy, a young worker told me about the child’s situation in a medical supermarket.
