A rainforest is an area{#blank#}1{#/blank#}(cover) by tall trees with the total high rainfall spreading quite equally through the year. Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate.{#blank#}2{#/blank#}the forest cover, these areas would reflect more heat into the atmosphere,{#blank#}3{#/blank#} (warm) the rest of the world. Losing the rainforests may also influence wind and rainfall patterns, potentially causing certain natural disasters all over the world.

    In the past hundred years, humans {#blank#}4{#/blank#}(begin) destroying rainforests in search of three major resources: land for crops, wood for paper and other products, land for raising farm {#blank#}5{#/blank#} (animal). This action affects the environment as a whole. For example, a lot of carbon dioxide in the air comes from burning the rainforests. People{#blank#}6{#/blank#}(obvious) have a need for the resources we gain from cutting trees,{#blank#}7{#/blank#} we will suffer much more than we will benefit.

    Rainforests are often called the world's drug store. More than 25% of the medicines we use today come from plants in rainforests. However, fewer than 1% of rainforest plants have been examined for their {#blank#}8{#/blank#}(medicine) value. It is extremely likely {#blank#}9{#/blank#}our best chance to cure diseases {#blank#}10{#/blank#}(lie) somewhere in the world's shrinking rainforests.

    Disneynature's new true life adventure film “Born in China' takes a journey into the wilds of China {#blank#}1{#/blank#}few people have ever gone. Following the stories of three animal families , the film transports audiences to some of {#blank#}2{#/blank#}most extreme environment on Earth to see some deeply moving moments. A caring panda mother gives guidance to{#blank#}3{#/blank#} (she) growing baby as she begins to explore and seek{#blank#}4{#/blank#}(independent) actively. A two-year-old golden monkey who feels unhappy with his new baby sister {#blank#}5{#/blank#}(run) away from home to join up with a group of free-spirited {#blank#}6{#/blank#} (monkey). And a mother snow leopard (雪豹)—an animal seldom caught on camera- faces the real challenge of raising her two babies.

    According to a review of evidence in a medical journal runners live three years{#blank#}1{#/blank#}(long) than non-runners You don't have to run fast or for long{#blank#}2{#/blank#}(see)the benefit You may drink, smoke, be overweight and still reduce your risk of {#blank#}3{#/blank#}（die）early by running.

    While running regularly can make you live forever, the review says it {#blank#}4{#/blank#} (be)more effective at lengthening life {#blank#}5{#/blank#}walking ,cycling or swimming. Two of the authors of the review also made a study published in 2014 {#blank#}6{#/blank#}showed a mere five to 10 minutes a day of running reduced the risk of heart disease and early deaths from all {#blank#}7{#/blank#}(cause).

    The best exercise is one that you enjoy and will do. But otherwise ……

It's probably running. To avoid knee pain, you can run on soft surfaces to {#blank#}8{#/blank#}(strength)your leg muscles(肌肉),avoid hills and get good running shoes. Running is cheap, easy and it's always {#blank#}9{#/blank#}(energy). If you are time poor, you need run for only half the time to get the same benefits other sports, so perhaps we should all give {#blank#}10{#/blank#}a try.

    There has been a recent trend in the food service industry toward lower fat content and less salt. This trend, which was started by the medical community（医学界）{#blank#}1{#/blank#}a method of fighting heart disease, has had some unintended side{#blank#}2{#/blank#}(effect) such as overweight and heart disease-the very thing the medical community was trying to fight.

    Fat and salt are very important parts of a diet. They are required{#blank#}3{#/blank#}(process) the food that we eat, to recover from injury and for several other bodily functions. When fat and salt{#blank#}4{#/blank#}(remove) from food, the food tastes as if is missing something. As {#blank#}5{#/blank#} result, people will eat more food to try to make up for that something missing. Even {#blank#}6{#/blank#} (bad), the amount of fast food that people eat goes up. Fast food{#blank#}7{#/blank#} (be) full of fat and salt; by {#blank#}8{#/blank#} (eat) more fast food people will get more salt and fat than they need in their diet.

    Having enough fat and salt in your meals will reduce the urge to snack(吃点心) between meals and will improve the taste of your food. However, be {#blank#}9{#/blank#} (care) not to go to extremes. Like anything, it is possible to have too much of both, {#blank#}10{#/blank#} is not good for the health.

    I had hardly sat down on the train and opened a bar of chocolate {#blank#}1{#/blank#} a really old man with huge bags sat down across from me. I said hello {#blank#}2{#/blank#} him, smiling sweetly and then I suddenly thought, "Why not offer him a piece of chocolate？" So I did. He was quite {#blank#}3{#/blank#} (surprise), but accepted and thanked me. He said that people didn't usually do things like this for {#blank#}4{#/blank#} (strange) and at least that was what I understood, because he was speaking a really {#blank#}5{#/blank#} (usual) dialect.

    Then he opened one of his bags and gave me {#blank#}6{#/blank#} handful of freshly picked cherries, {#blank#}7{#/blank#} (explain) that he had just taken them from his orchard. The cherries were really lovely, better than those in the shops, and I enjoyed them very much. It had been just an impulse (冲动) to offer him a piece of chocolate, but if I {#blank#}8{#/blank#} (not do) so, I would never have tasted those lovely cherries, {#blank#}9{#/blank#} I didn't even know he had at the time. Life is about giving and taking, and it's {#blank#}10{#/blank#} (general) true that if you give, you will receive.
