Question

   For more than 10 years,the “SAS Survival Guide,” a book about outdoor tips by John “Lofty” Wiseman,has been a necessity in my camping backpack. The 400-page handbook usually comes with me on camping trips and has helped me search for food or use the sun and stars to find my way. But whenever I fly,I leave the book behind. However,what would happen if my plane crashed on a deserted island? Could I possibly create shelter from whale bones without this guide?

   But no fear: the “SAS Survival Guide” comes in an app(应用程序) and it's every bit as terrific as the book.

   The user-friendly app includes guidelines from the book,and then some. There are tips for building a fire,treating a snake bite and searching for mushrooms. The first aid guide includes instructions for saving yourself if you are choking. And there are warnings: If you happen to kill a polar bear,Wiseman warns,do not eat the liver(内脏) ，because it contains deadly amounts of vitamin A.

   Sixteen videos show Wiseman teaching survival techniques,including one in which he kills a chicken. aSave the feathers. They can be useful for insulating (绝缘) clothing ,” he advises. But don't worry,no chickens were harmed in the testing of this app.

   In other videos,Wiseman shows how to build shelter from plants with feathery green leaves,how to obtain drinkable water with a bag and how to construct a house from blocks of hard snow or ice. 

   There is room for improvement. Step-by-step videos would be more helpful than a series of pictures showing varipus knot (结) types. And the search function is complicated. On a recent camping trip,I ran across a black bear. Backing away,I searched the app for “bear,” which gave me more than 50 hits,including “bearings." Worried the bear would attack me as I looked through the results,I instead made a wide arc (弧) around her along the bank of a river. Fortunately,this was the right course,I later learned.

   Still,it's a helpfiil app. If only Wiseman had tips on keeping a cellphone's battery life in the wilderness.
