A long walk in the desert or the mountains can be exciting. And it’s a great way to keep fit. If you carry a tent and some food, you can camp overnight. But wild places can be dangerous. Here’s how you can enjoy walking and camping safely.

Before your trip

☆ Tell someone where you are going and when you expect to return. If you don’t return on time, the people at home will know that you are lost or in trouble. They will know where to look for you.

☆ Make sure you’ve got a good map of the area that you’re going to.

☆ Make sure you’ve packed the right equipment for your activities. The desert is often hot, but nights can be very cold, and sometimes there are big rainstorms. In the mountains, the weather can change suddenly. A sunny day can turn cold and cloudy quickly.

The tools for survival(生存)

Sunglasses, sun hat, sun cream, windproof jacket, good walking shoes or boots, food, water, maps, compass, first-aid kit, matches, rope, knife, ground sheet,

the pack to carry your equipment.

What to do if you get lost

☆ If you’re in a car and it has broken down, stay with your car.

☆ If you are not traveling by car, make yourself easy to see. A signal fire can be seen at night. During the day, smoke may be used to show where you are. A brightly-colored blanket(毯子) may help rescuers to find you.

☆ Stay where you are.

☆ If you walk for any reason, avoid walking during the hottest part of the day. Morning and evening walking is better for saving your energy water.

☆ Keep yourself away from the rain, wind and sun, but remember: try to make yourself be in sight.

插入排序算法的主要思想:每次从未排序序列中取出一个数据,插入到己排序序列中的正确位置。Insert类的成员函数sort()实现了插入排序算法,请填空。
class Insert
public:
Insert(int *b0,int n0):b(b0),n(n0);//参数b0是某数组首地址,n是数组元素个数
void sort()
//此函数假设已排序序列初始化状态只包含b[0],未排序序列初始为b[1]...b[n-1]
for(int i=1;i<n;++i)

int t=b[i];
int j;
for(______;j>0;--j)

if(t>=b[j-1])
break;
b[j]=b[j-1];
b[j]=t;
