Each and every one of us is responsible for the greenhouse        nts should the need arise-as it almostpected, and is prepared to   tion, something comes along to gases we give out in our daily actions and choices.Therefore,combating climate change is going to take the combined efforts of everyone on the planet.

The average household carbon footprint in China is 2.41 tons of carbon dioxide annually.That's enough to fill half an Olympic swimming pool.

Surprised? Well,.here's how you can work to reduce it:

1.Take showers rather than baths and reduce your shower time by two minutes.This will save water and give you an extra two minutes in bed.

2.Don't purchase unnecessary clothes,and be careful about the materials you buy.Wool and cotton have a really high greenhouse gas impact.Manmade fibers are a better choice.

3.Try to buy high-quality,long-lasting products even though they    .A laptop is more efficient than a desktop,and a small screen TV is better than a big flat-screen.

4.Only turn the water heater on when necessary,and adjust temperature controls to avoid overheating.Put a lid on a pan when boiling water.

5.When using the washing machine,be sure there's a full load and turn the temperature down if it's not really dirty.

6.The greediest home device along with the washing machine is the fridge.Make sure it's as efficient as possible by keeping it out of direct sunlight and away from the oven or heater.Don't put food in when it's still warm.

7.Only buy the amount of food you need and if there are leftovers,get creative.For instance,make them into a soup.Ask to take food home from restaurants if there's some left,but remember to take your own container to avoid using a disposable carton.

[说明]
设有一个带头结点的双向循环链表L,每个结点有4个数据成员:指向前驱结点的指针prior、指向后继结点的指针next、存放数据的成员data和访问频度freq。所有结点的freq初始时都为0。每当在链表上进行一次L.Locate(x)操作时,令元素值x的结点的访问频度freq加1,并将该结点前移,链接到现在它的访问频度相等的结点后面,使得链表中所有结点保持按访问频度递减的顺序排列,以使频繁访问的结点总是靠近表头。
[函数]
void Locate(int &x)
<结点类型说明>
*p=first->next;
while(p!=first && (1) )p=p->next;
if(p!=first)
(2) ;
<结点类型说明>
*current=p;
current->prior->next=current->next;
current->next->prior=current->prior;
p=current->prior;
while(p!=first && (3) )p=p->prior;
current->next= (4) ;
curren->prior=p;
p->next->prior=current;
p->next= (5) ;
