  Happiness exists everywhere．You 46 care about those people who ownbeautiful houses with large gardens and swimming pools or those    47  have nice cars and a lot of money and so on．Why? Because the people who have big houses may often feel  48  and those who have cars may want to walk on the country  49  in their free time．

     In fact，happiness is always around you if you put your ­­­­ 50   into it．When you

are  5 1  trouble at school，your friends will help you；when you study hard at your

lessons，your parents are  52 taking good care of your life and your health；when

you get  53，your friends will say congratulations to you；when you do  54   ，

people around you will help you to correct it．And when you do something good to

others，you will feel happy，too．All these are your happiness．If you notice 55

them，you’II see happiness is around you．

Happiness is not the same  56  money．It is a  57  of your heart．When you

are poor．you can also say you are very happy，because you have something else that

can’t  58  with money．When you meet with difficuhies，you can say loudly that

you are very happy，because you have more chances to 59  yourself .So you can’t

always say you are poor and you have bad luck．As the saying goes, “Life is like a revolving(旋转的)   60  ．When it closes，it also opens”．If you take every chance you get，you can be a happy and lucky person．
