On average, their population dropped by more than 50 percent in the 1980s and 1990s. The government took effective measures to protect them, and now the population has recovered.

This is ____________ we're here—to ____________ (观察) Tibetan antelopes. 【语篇功能】开篇点题·目的 【语法】why引导表语从句；不定式作目的状语 2. I'm also ____________ (提醒) the danger they are in. They ____________ ____________ ____________ (hunt), illegally, for their valuable fur. 【语篇功能】矛盾冲突 【语法】remind sb of sth被动语态；现在进行时被动are being hunted 3. His job is to ____________ ____________ (照看) the antelopes ____________ ____________ (日夜), keeping them safe from attacks. 【语篇功能】具体措施 【语法】不定式作表语；现在分词短语作伴随状语 4. In order to save this ____________ (物种) from extinction, the Chinese government placed it under national protection and ____________ ____________ (建立) the Changtang National Nature Reserve. 【语篇功能】政府行动 【语法】in order to do作目的状语；并列谓语 5.

Only when we learn to ____________ (存在) in harmony with nature ____________ we stop being a threat to wildlife. 【语篇功能】升华主旨 【语法】Only+状语从句置于句首，主句部分倒装 六、单元语法知识串联——现在进行时的被动语态 【三种被动时态对比】 时态 结构 用法 标志词 例句 一般现在时被动 am/is/are done 经常性、习惯性的被动动作；客观事实 often, usually, every day The antelopes are protected by law. 现在进行时被动 am/is/are being done 此时此刻或现阶段正在进行的被动动作 now, at present, these days They are being hunted for their fur. 现在完成时被动 have/has been done 已经完成的被动动作，强调对现在的影响 already, yet, recently The reserve has been established. 【易错提醒】 1. being不能省略：are being hunted（正在被猎杀）≠ are hunted（经常被猎杀）。 2. 状态动词无进行时被动：know, love, belong to, have, contain等不用于进行时态。 3. 与be being + adj.区分：be being + adj.表"暂时表现得……"（He is being careless.），不是被动语态。 用括号内动词的适当形式填空（语篇：东北虎豹国家公园）： The Northeast China Tiger and Leopard National Park, which covers an area of 14,000 square kilometers, ____1____ (establish) in 2021. At present, the habitats of Siberian tigers ____2____ (restore) by the government. Many trees ____3____ (plant) in the park these days to provide more shelter for the big cats.
