(3)What does Zhaxi mean by saying “We're not trying to save the animals”“Actually，we're trying to save ourselves”？ To protect wild animals is to protect human beings themselves. 2．Read Paras. 4－5 and answer the following questions. (1)What made the population of antelopes drop so badly in the 1980s and 1990s? A．The extreme climate. B．A serious disease. C．Being hit by cars and trains.

several times on the short hike② from camp.To our left③，snow-covered④ mountains disappear into clouds that seem almost close enough to touch.On the plain⑤ in front of us，we can just make out⑥ a herd⑦ of graceful⑧ animals.This is why we're here—to observe⑨ Tibetan antelopes. 动词不定式(短语)作程度状语。enough to do sth意为“足以做某事”。 此处why引导表语从句。 　　Tibetan antelopes live on the plains of Xizang，Xinjiang，and Qinghai.Watching them move slowly across the green grass，I'm struck by⑩their beauty⑪.I'm also reminded of⑫ the danger they were in.They were hunted，illegally，for their valuable fur⑬. 动词-ing形式短语作时间状语。watch与主语是逻辑上的主谓关系，与谓语动词表示的动作同时进行。其中包含“watch＋宾语＋宾补”结构，此处表示目睹了藏羚羊穿过草地的全过程，故用不带to的动词不定式move作宾语补足语。 　　My guide is Zhaxi，a villager from Changtang.He works at the Changtang National Nature Reserve.The reserve is a shelter⑭ for the animals and plants of northwestern Xizang.To Zhaxi，the land is sacred⑮ and protecting the wildlife isa way of life.“We're not trying to save the animals，”he says.“Actually，we're trying to save ourselves.” 此处作Zhaxi的同位语。 单个的动词-ing形式短语作主语，谓语动词应用单数形式。 　　The 1980s and 1990s were bad times for the Tibetan 学生用书第41页 antelope.The population dropped by⑯ more than⑰ 50 percent.Hunters were shooting⑱ antelopes to make profits⑲.Their habitats were becoming smaller as new roads and railways were built. as在此处表示“随着……”，引导时间状语从句。 　　In order to save this species from extinction，the Chinese government placed it under national protection⑳.Zhaxi and other volunteers watched over㉑ the antelopes day and night㉒ to keep them safe from attacks㉓.Bridges and gates were added to let the antelopes move easily and keep them safe from cars and trains. 动词不定式短语作目的状语。“keep...attacks”是“keep＋宾语＋宾语补足语”结构，形容词短语safe from attacks作宾语补足语。 　　The measures were effective㉔.The antelope population has recovered㉕ and in June 2015，the Tibetan antelope was removed㉖ from the endangered species list.The government，however，does not intend㉗ to stop the protection programmes，since the threats㉘ to the Tibetan antelope have not yet disappeared. since表示“因为”，引导原因状语从句。 In the evening，I drink a cup of tea and watch the stars.I think about the antelopes and what Zhaxi told me.Much is being done 10to 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 with㉙ nature can we stop being a threat to wildlife and to our planet.11 此处为what引导的宾语从句，作think about的宾语。 10现在进行时的被动语态。 11“only＋状语从句”位于句首时，主句要用部分倒装，即将be动词、助动词或情态动词放到主语的前面。该句的正常语序是We can stop being a threat to wildlife and to our planet only when we learn to exist in harmony with nature。 学生用书第42页 ◎ 在云间度过的一天 由于空气稀薄，在离开营地的短途徒步旅行中，我们不得不多次休息。在我们的左方，白雪皑皑的群山消失在似乎触手可及的云层中。放眼平原，我们隐约看到一群体形优美的动物。这就是我们来到此地的原因——观察藏羚羊。 藏羚羊生活在西藏、新疆和青海的平原上。看着它们缓缓穿过绿色的草地，我被其美丽所震撼，也想到了它们所处的险境。因其珍贵的羊毛，它们被非法猎杀。 我的向导扎西是一位来自羌塘的村民。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庇护所。对扎西来说，这片土地是神圣的，保护野生动植物是一种生活方式。“我们不是在试图拯救动物，”他说。“事实上，我们是在试图拯救自己。” 对藏羚羊来说，二十世纪八九十年代是一个悲惨的时代。藏羚羊数量少了50%以上。猎人们为了谋利而射杀藏羚羊。随着新公路和铁路的修建，藏羚羊的栖息地也不断缩小。 为了使这一物种免遭灭绝，中国政府将其置于国家保护之下。扎西和其他志愿者日夜看护着藏羚羊，保护它们免受攻击。新增的一些桥梁和涵洞，便于藏羚羊自由穿行，防止它们撞上汽车和火车。 这些措施效果明显。藏羚羊数量已经恢复。2015年6月，藏羚羊被移出濒危物种名单。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。 夜晚时分，我喝着茶，仰望星空。心里想起藏羚羊以及扎西对我说的那番话。大量的工作正在进行中以保护野生动植物，但是我们如果真想拯救地球，就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。 ◎核心单词——练通
