求翻译：　　Clearly, it is necessary to pack a small first-aid kit with you if you go traveling. The kit should contain necessary medicine, sun cream, insect spray and some bank-aid. In addition to that, loose-fitting clothing, long dresses, long trousers and long-sleeved shirt fastened at the end are needed when traveling long distances outdoors.
