阅读，选择适当的单句填空，将其代码填在答题纸的横线上。 （每空1分，共4分） Happiness is for everyone. You don’t need to care about those people who have beautiful houses with large gardens and swimming pools or 1．________ and so on. Why? Because those who have big houses may often feel lonely（孤独的）and those who have cars may want to walk on the country roads at their free time. In fact, happiness is always around you if you put your heart into it. 2．________. When you study hard at your lessons, your parents are always taking good care of your life and your health. When you get success, your friends will say congratulations（祝贺）to you. When you do something wrong, people around you will help you to correct it. 3．________. All these are your happiness. If you notice（注意到） a bit of them, you can see that happiness is always around you. Happiness is not the same as money. It is a feeling of your heart. When you are poor, you can also say you are very happy, because you have something else that can’t be bought with money. When you meet with difficulties, you can say loudly you are very happy, because you have more chances to challenge（挑战）yourself. So you cannot always say you are poor and you have bad luck. As the saying goes, life is like a revolving（旋转的）door. When it closes, it also opens. 4．________.
