However depressed you may be feeling now, if you look back, there certainly will have been events that made you happy—maybe the time {#blank#}1{#/blank#} you bought your first bicycle or you were awarded a scholarship. When good things happen, we feel excited, proud and happy.

    But the problem is, happiness doesn't usually last. The excitement of that first bicycle purchase wears off, and the pride in the scholarship gives way to the stress of performing {#blank#}2{#/blank#} (well) on the next exam.

    Psychologists call this phenomenon hedonic adaptation (享乐适应症)—that is, {#blank#}3{#/blank#} good something makes us feel, most of the time we drift back to {#blank#}4{#/blank#} we started. An often {#blank#}5{#/blank#} (quote) example is that lottery winners are no happier than non-winners eighteen months after their win.

    But don't despair. It is possible to make happiness last. Psychologists have found two anti-adaptation tools that are effective in sustaining happiness: variety and appreciation.

    Variety is, as we all know, the spice of life. But it's also a useful weapon {#blank#}6{#/blank#} adaptation. Positive changes that {#blank#}7{#/blank#} (experience) in a variety of ways are more likely to lead to lasting happiness. For example, you will feel happier about your volunteer work{#blank#}8{#/blank#} you are able to cope with new tasks every week. The second tool, appreciation, is in many ways the opposite of adaptation. It's about focusing on something, instead of letting it fade into the background. It is only when you appreciate something {#blank#}9{#/blank#} an enduring feeling of happiness will follow.

    Human beings spend a lot of time figuring out what makes them happy, but not enough time {#blank#}10{#/blank#} (try) to hang on to the happiness they already have. This is like focusing all your energy on making more money, without giving any thought to what you will do with the money. The key to happiness is to not only look for new opportunities but also to make the most of the ones you've been given.

There are many kinds of festivals throughout the world. Festivals {#blank#}1{#/blank#}(hold) to satisfy and please the ancestors, to honour some famous people {#blank#}2{#/blank#} important events, and to express people's gratitude to the God for bringing {#blank#}3{#/blank#} a year of plenty. For example, Japanese observe Obon, people go to clean graves and light incense {#blank#}4{#/blank#} memory of their ancestors. In India. October 2 is a national festival{#blank#}5{#/blank#} (honour) Mohandas Gandhi. who helped India become an {#blank#}6{#/blank#} (depend) country.  And in China the Spring Festival, {#blank#}7{#/blank#} is celebrated in January or February, is{#blank#}8{#/blank#}most energetic and important festival because it is a festival that {#blank#}9{#/blank#} (look) forward to the coming of spring. Why are all these festivals everywhere？Because during the festivals, people can get together to eat, drink and have fun with each other, {#blank#}10{#/blank#} (forget) all the daily struggles and demands for a while.
