Section ⅡReading and Thinking基础知识预习自检在云端的一天空气稀薄，我们不得不在离营地不远的徒步旅行中休息几次。
在我们的左边，被雪覆盖的山峰消失在云层中，那些云看起来似乎触手可及。
放眼平原，我们隐约看到一群体形优美的动物。
这是我们来到这里的原因——去观察藏羚羊。
藏羚羊住在西藏、新疆和青海的平原上。
看着它们缓慢地穿过绿草地，我被它们的美丽所震撼。
我也想起它们身处险境。
因为它们珍贵的皮毛，它们正遭受非法猎杀。
我的向导叫扎西，是长塘的村民。
他在长塘自然保护区工作。
这个保护区是西藏西北部动物和植物的避难所。
对扎西来说，土地是神圣的，保护野生动物是一种生活方式。
“我们不是在保护动物，”他说：“实际上，我们是在保护我们自己”。
20世纪80年代和90年代，藏羚羊经历了一段艰难时期。
藏羚羊的总数量急剧下降超过百分之五十。
偷猎者射杀藏羚羊来获取利益。
它们的栖息地也因为新公路和铁轨的建成而变得越来越狭小。
为了保护这个物种不灭绝，中国政府将其置于国家保护之下。
为了它们免于受到攻击，扎西和其他的志愿者昼夜看守这些藏羚羊。
桥和门被添加，让藏羚羊容易移动，使它们安全远离汽车和火车。
采取的措施很有效。
藏羚羊的数量在2015年6月已经恢复，并且藏羚羊从濒临物种名单上被移除。
然而，政府并不打算终止藏羚羊保护项目，因为对藏羚羊的威胁还没有完全消失。
晚上，我喝着茶看着星空。
我想着藏羚羊和扎西对我说的话。
采取了很多措施去保护野生动物，但是如果我们真的想拯救这个星球，我们必须改变我们的生活方式。
只有学会和自然界和谐相处，我们才不会成为野生生物和地球的威胁。

在日常生活中如何保护野生动植物呢，一起来看看文中提出了哪些做法。
Wildlife faces threats from habitat① destruction, pollution and other human actions. Althoughprotecting wildlife can seem overwhelming at times, even small actions in your own neighborhood canhelp protect many different animals.Create wildlife friendly areas in your backyard. You can choose native plants that can provide food andshelter to native wildlife. This will also help cut down on pollution. Add bird or bat houses to your yard orgarden to attract and shelter these species.Avoid disrupting② the natural ecosystem in your area. Non-native plants or animals can destroy habitats, particularly if there is no natural predator③ to keep the species in check. Invasive plants can kill or disrupt native plants that provide food and shelter for wildlife.Have a greener lifestyle. By conserving water and fossil fuels④，you will behelping to protect the wildlife around you. Take public transportation when you can,turn off electric devices when you're not using them. Become knowledgeable about what contributes to global warming, what disrupts migration patterns and habitats.Buy products that are wildlife friendly. Avoid products that are made from threatened or endangered animals. Keep in mind that some endangered animals are killed by traps, snares or hunters who are after other wildlife within the same habitat.Talk to or write to policymakers about protecting wildlife. Discuss ways to help animals with friends and family members.Limit family size. Population growth is one of the major factors in habitat destruction. By living in established city limits and limiting family size to around two children per family, the earth's population will stabilize⑤ and native habitats can be protected.【注】①habitat n. (动物的)栖息地②disrupt v. 扰乱③predator n. 捕食性动物④fossil fuel 化石燃料(如煤、石油等)⑤stabilize v. (使)稳定【立德树人】如果没有野生动植物，地球上的人类也延续(continue)不下去，野生动植物帮我们制造氧气、食物、提供各种资源，没有野生动植物就没有人类(No wildlife, no humans)。
