CLOUDSThe air is thin and we have to rest several times on the short hike from camp.To our left，snow­covered mountains disappear into clouds that seem almost close enough to touch1On the plain in front of us，we can just make out a herd of graceful animals.This is why 2 we're hereto observe Tibetan antelopes31that seem almost close enough to touch是that引导的定语从句，修饰clouds，关系词在从句中作主语。2This is why.这就是的原因。(why后跟结果)This is because.这是因为(because后跟原因)3不定式短语to observe Tibetan antelopes作状语，具体解释来这里的原因。Tibetan antelopes live on the plains of Tibet，Xinjiang，and Qinghai.Watching them move slowly across the green grass4，I'm struck by their beauty.I'm also reminded of the danger they are in5They are being hunted6，illegally，for their valuable fur.4现在分词短语Watching them move.在句中作时间状语。5they are in是定语从句，关系词(that/which)因在从句中作宾语而被省略了。6are being hunted是现在进行时的被动语态，构成：am/is/are being done。My guide is Zhaxi，a villager from Changtang7He works at the Changtang National Nature Reserve.The reserve is a shelter for the animals and plants of northwestern Tibet.To Zhaxi，the land is sacred and protecting the wildlife8 is a way of life.“We're not trying to save the animals，”he says.“Actually，we're trying to save ourselves.”7a villager from Changtang作Zhaxi的同位语。8动名词短语protecting the wildlife作主语，谓语动词用单数。The 1980s and 1990s were bad times for the Tibetan antelope.The population dropped by more than 50 percent.Hunters were shooting antelopes to make profits.Their habitats were becoming smaller as new roads and railways were built99as new roads and railways were built是as引导的原因状语从句，as表示“因为，由于”。In order to10 save this species from extinction，the Chinese government placed it under national protection.Zhaxi and other volunteers watched over the antelopes day and night to keep them safe from attacks.Bridges and gates were added to let the antelopes move easily and keep them safe from cars and trains.10 in order to.“为了”，在句中作目的状语。so as to.为了(不可用在句首)The measures were effective.The antelope population has recovered and in June 2015，the Tibetan antelope was removed from the endangered species list.The government，however，does not intend to stop the protection programmes，since the threats to the Tibetan antelope have not yet disappeared1111since在句中引导原因状语从句，since表示“因为”。In the evening，I drink a cup of tea and watch the stars.I think about the antelopes and what Zhaxi told me12Much is being done to protect wildlife，but if we really want to save the planet，we must change our way of life.Only when we learn to exist in harmony with nature can we stop being a threat to wildlife and to our planet1312what Zhaxi told me是what引导的宾语从句，和the antelopes一起作think about的宾语。13“only状语从句”提至句首以示强调时，后面的主句要用部分倒装，即把助动词、情态动词或连系动词be提到主语前面。译文参考在云端的一天空气稀薄，我们不得不在营地的短途远足中休息几次。在我们的左边，白雪覆盖的群山消失在云层中，云层似乎近在咫尺，触手可及。放眼平原，我们隐约看到一群体形优美的动物。这就是我们来这里的原因观察藏羚羊。藏羚羊生活在西藏、新疆和青海的平原上。看着它们慢慢地穿过绿色的草地，我被它们的美丽所打动。我也意识到了它们所处的危险。因其珍贵的羊毛，它们(藏羚羊)正遭受非法猎杀。我的导游是扎西，一个来自羌塘的村民。他在羌塘国家级自然保护区工作。该保护区是西藏西北部动植物的避难所。对扎西来说，土地是神圣的，保护野生动物是一种生活方式。“我们不是在试图拯救动物，”他说。“事实上，我们是在拯救自己。”二十世纪八九十年代是藏羚羊的艰难时期。数量下降了50%以上。猎人们猎杀藏羚羊以获利。因为新的公路和铁路的修建，它们的栖息地变得越来越小。为了拯救这一物种免于灭绝，中国政府将其置于国家保护之下。扎西和其他志愿者日夜守护着这些藏羚羊，保护它们免受攻击。公路和铁路上的桥和门增加了，让藏羚羊容易行动，使它们安全，远离汽车和火车。这些措施是有效的。藏羚羊的数量一直在恢复，2015年6月，藏羚羊从濒危物种名单中被移出。然而，政府并没有打算停止这些保护项目，因为对藏羚羊的威胁依然存在。在晚上，我喝着茶，仰望着星空。我想起了藏羚羊以及扎西对我说的话。我们在保护野生动物方面做了很多工作，但是如果我们真的想拯救地球，我们必须改变我们的生活方式。只有学会和大自然和谐共处，我们才不会成为野生生物和地球的威胁。-
