Most people want to be happy but few know how to find happiness. Money and success don't bring lasting happiness. Happiness depends on ourselves. In other words, we make our own happiness.Some people believe that if they arewealthy, with the money they will be able to do anything they want, which means happiness. On the other hand, some people believe that holding a high position in the government is happiness. In this way, you have not only money, but also many other things which can't be bought by money. However, other people believe that having lots of money is not happiness, nor is holding a high position in the government. These people value(重视) their beliefs, or their intelligence, or their health. They think these can make them happy. Here are a few ways to help you be happier.The first secret of happiness is to enjoy the simple things in life. Too often, we spend so much time thinking about the future, for example, getting into college or getting a good job, that we don't enjoy the present. You should enjoy life's simple pleasures, such as reading a good book, listening to your favorite music, or spending time with close friends. People who have close friends usually enjoy happier and healthier lives.The second secret of happiness is to be active. Many people go dancing or play sports. People can forget about their problems and only think about the activities. Finally, many people find happiness in helping others. According to studies, people feel good when they volunteer their time to do many meaningful things for other people. If you want to feel happier, do something nice for someone. You can help a friend with his or her studies, go shopping to get food for an old neighbor, or simply help around the house.Now maybe you know how to find happiness!【1】The underlined word “wealthy” means “__________” in the article.A. pleased B. healthy C. excited D. rich【2】Some people who hold a high position in the government think they can _________.A. get money and something they can't buy with moneyB. do what they want to do at any timeC. enjoy health which makes them work hardD. take an active part in all kinds of activities every day【3】The writer thinks the secret of happiness is that people ___________.A. think about getting moneyB. think of presents they don't likeC. often spend time with close friendsD. often spend time on entering the college【4】Many people find it happy to ___________.A. remember the old days and troublesB. do some meaningful things for othersC. go shopping to buy some foodD. make much money and little success【5】The passage mainly tells us __________.A. how to find happinessB. how to save happinessC. to do something good for othersD. to value our beliefs or health
