新鲜空气真的对你有好处吗？
我们都是听别人叫我们“出去呼吸新鲜空气”长大的。根据最近的研究，如果你露营区的空气质量好，答案是肯定的。
37如果你呼吸的空气是干净的——如果你远离城市的烟雾——那么空气中充满了赋予生命的氧气。如果你在户外锻炼，你的身体会学会深呼吸，让更多的氧气进入你的肌肉和大脑。
最近，人们开始研究自然世界和治疗之间的联系。在这些地方，病人在康复期间可以接近大自然。结果发现，只看绿色，生长的东西可以减轻压力，降低血压，让人心情更好（情32490;）。绿色植物对我们有好处。医院里看到窗外树枝的病人比看到建筑物或天空的病人恢复得更快。39它给我们一种伟大的和平感。
40虽然阳光会老化并伤害我们的皮肤，但它们也会给我们提供有益的维生素D。为了确保你得到足够的维生素D——但仍然能保护你的皮肤——在你出门的时候涂上防晒霜。防晒霜大约需要15分钟才能开始工作，而你的皮肤有足够的时间吸收一天的维生素d。
新鲜空气清洁我们的肺。
那你还在等什么呢？
在大自然中使我们精神振奋。
获得新鲜空气的另一个好处是阳光。
但是新鲜空气真的像你妈妈常说的那样对你有好处吗？
同样重要的是，我们倾向于把新鲜空气与医疗联系起来。
在全国各地，康复中心已经开始建设康复花园。
Every year about 40000 people attempt to climb Kilimanjaro the highest mountain in Africa. They 41 with them lots of waste. The 42 might damage the beauty of the place. The glaciers（冰川）are disappearing changing the 43 of Kilimanjaro.
Hearing these stories I’m 44 about the place — other destinations are described as ＂purer＂ natural experiences.
However I soon 45 that much has changed since the days of disturbing reports of 46 among tons of rubbish. I find a 47 mountain with toilets at camps and along the paths. The environmental challenges are 48 but the efforts made by the Tanzania National Park Authority seem to be 49 .

The best of a Kilimanjaro 50 in my opinion isn’t reaching the top. Mountains are 51 as spiritual places by many cultures. This 52 is especially evident on Kilimanjaro as 53 go through five ecosystems（生态系统）in the space of a few kilometers. At the baxxxxse is a rainforest. It ends abruptly at 3 000 meters 54 lands of low
growing plants. Further up the weather 55 — low clouds envelope the mountainsides which are covered with thick grass. I 56 twelve shades of green from where I stand. Above 4 000 meters is the highland 57 : gravel（砾石） stones and rocks. 58 you climb into an arctic-like zone with 59 snow and the glaciers that may soon disappear.
Does Kilimanjaro 60 its reputation as a crowded mountain with lines of tourists ruining the atmosphere of peace? I found the opposite to be true.

每年约有4万人试图攀登非洲最高的山峰乞力马扎罗。他们41岁，有很多废物。这42个可能会破坏这个地方的美丽。冰川正在消失，改变了乞力马扎罗的43个冰川。
听了这些故事，我44岁了，对这个地方-其他目的地被描述为“纯粹”的自然体验。
然而，我很快就改变了45吨垃圾中有46吨令人不安的报道。我发现一座47座山，营地和小路上都有厕所。环境挑战是48个，但坦桑尼亚国家公园管理局的努力似乎是49个。
在我看来，乞力马扎罗50的最好成绩并没有达到顶峰。在许多文化中，山是51个精神场所。这52年在乞力马扎罗尤为明显，因为53年在几公里的空间里经历了五个生态系统。基地是一片雨林。它在3000米处突然结束，54片低矮植物的土地。再往上看，55度的低云笼罩着山坡，山坡上覆盖着厚厚的草。我站在那里有56个12度的绿色。海拔4000米以上是57高地：砾石、石头和岩石。58你会爬进一个有59层雪和可能很快消失的冰川的北极地带。
乞力马扎罗山60号是不是有一座拥挤的山，成群结队的游客破坏了和平的气氛？我发现事实恰恰相反。

The polar bear is found in the Arctic Circle and some big land masses as far south as Newfoundland. While they are rare north of 88° there is evidence 61 they range all the way across the Arctic and as far south as James Bay in Canada. It is difficult to figure out a global population of polar bears as much of the range has been 62 (poor) studied; however biologists calculate that there are about 20000-25000 polar bears worldwide.
Modern methods 63 tracking polar bear populations have been employed only since the mid-1980s and are
expensive 64 (perform) consistently over a large area. In recent years some Inuit people in Nunavut 65 (report) increases in bear sightings around human settlements leading to a 66 (believe) that populations are increasing. Scientists have responded by 67 (note) that hungry bears may be congregating(聚集) around human settlements leading to the illusion(错觉) that populations are 68 (high) than they actually are. Of 69 nineteen recognized polar bear subpopulations three are declining six 70 (be) stable one is increasing and nine lack enough data.
北极熊发现于北极圈和一些大的陆地，南至纽芬兰。虽然它们在88°以北很罕见，但有证据表明61年来它们一直延伸到北极，并一直延伸到加拿大的詹姆斯湾以南。很难计算出全球北极熊的数量，因为大部分北极熊的分布范围已经被研究过62只（可怜）；然而，生物学家计算，全世界大约有20000-25000只北极熊。

现代跟踪北极熊种群的方法63只从20世纪80年代中期才开始使用，在大范围内持续使用的费用高达64只（perform）。近年来，努纳武特65的一些因纽特人（报道）在人类住区周围看到熊的人数增加，导致66人（相信）人口在增加。科学家们的回答是67（注）饥饿的熊可能聚集在人类住区周围，导致人们产生一种错觉，认为熊的数量比实际数量高68（高）。在69个已知的北极熊亚种群中，有3个在下降，6个稳定，1个在增加，9个缺乏足够的数据。
I became interesting in playing football thanks to a small accident. One afternoon where I was in primary school I was walking by the school playground. Suddenly football feel just in front of me but almost hit me. I stopped the ball and kicked it hardly back to the playground. To everyone`s surprising the ball went into the net. All the
football plaxxxxyer on the playground cheered loudly say that I had a talent for football. From now on I started to play my football with classmates after school. I am a good plaxxxxyer now.
由于一次小事故，我对踢足球很感兴趣。一天下午，在我上小学的时候，我正在学校操场旁散步。突然，足球感觉就在我面前，但几乎击中了我。我把球停下来，几乎没把它踢回操场。出乎意料的是，球进了网。操场上所有的足球运动员都大声欢呼，说我有足球天赋。从现在起，放学后我开始和同学们踢足球。我现在是个好球员。
