The giant panda loves bamboo. An adult panda requires 12.5 kilograms of bamboo, which it{#blank#}1{#/blank#}(hungry) pulls out with its powerful paws, to satisfy its daily needs. Wild pandas live only in the high bamboo forests of Central China. These mountain forests are cool and wet--just as pandas like it. In the summer, they may climb as high as 4000 meters to help themselves to bamboo {#blank#}2{#/blank#}（grow) at higher altitudes. Frequently, pandas{#blank#}3{#/blank#}(see) eating in a relaxed sitting position, with their back legs stretched out before them.{#blank#}4{#/blank#} they may appear inactive, they are in fact skilled tree-climbers and efficient swimmers.

    Giant pandas are unsociable. They have a highly developed sense of smell that males use{#blank#}5{#/blank#}(avoid) each other and to find females for mating in the spring. After a five-month pregnancy, a female gives birth {#blank#}6{#/blank#} a cub. The blind baby pandas weigh only 142 grams and cannot crawl(爬行){#blank#}7{#/blank#} they reach three months of age{#blank#}8{#/blank#} are born white, and develop their much loved coloring later.

    There are only about 1000 giant pandas left in {#blank#}9{#/blank#} wild, with perhaps another 100 in zoos. Because they are so rare, much of{#blank#}10{#/blank#} we know about pandas comes from studying these zoo animals.

    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.

Coffee is probably world's least expensive success power tool to increase focus, drive and even the life span. {#blank#}1{#/blank#}(fortunate) we may not be enjoying its benefits or pleasure too much longer. According to ecologists，there is a good chance {#blank#}2{#/blank#} the varieties of coffee that we drink today {#blank#}3{#/blank#}(be) extinct in 20 or 30 years. The problem, of course, is the pace of climate change.

Coffee is a crop that is only grown in a thin band {#blank#}4{#/blank#}(call) the "coffee belt" close to equator(赤道), which is extremely vulnerable(易受...伤害的) to climate change. If the air is too hot {#blank#}5{#/blank#} too cold, it prevents the growth of coffee plant. Climate change also creates {#blank#}6{#/blank#}(environment) stress, which spreads pests and plant diseases. Almost all the coffee grown in the world today is one of two species, arabica or robuasta, both of {#blank#}7{#/blank#} might be wiped out in this way. There are other species existing only in Ethiopia, {#blank#}8{#/blank#}country that climate change is happening. In other words, climate change is eating away the root source that we might turn to {#blank#}9{#/blank#}replacement species.

What to do? Well, take the time {#blank#}10{#/blank#}(enjoy) each cup of coffee you drink.
