In the natural world, rarity is most clearly represented by the last members of a declining species. These scarce(稀少的) plants and animals are extremely valuable; they represent the final hope for preventing extinction. The efforts toward conserving rare species have made an enormous difference. In the past few decades, declines of many endangered plants and animals have been reversed (逆转)．But the attention to rarity could come at the expense of overlooking the ordinary. If we are to conserve nature, we must maintain our focus on the familiar. Increasingly, conservation is turning its sights in this direction—to safeguard what is common, not just what is rare. There are good reasons to consider the common. A study of North American birds uncovered that we have lost three billion birds on this continent within the past two generations. These declines include species once considered widespread and secure, like the common redpoll, whose numbers are down by 29 million and the common nighthawk, down by 26 million. The shocking losses are a reminder that the mark of a species in trouble is not rarity, but the rate of decline. Notably, the shifts in abundance of common species can translate into sizeable shifts in ecosystem functioning. One caribou herd(北美驯鹿群), numbering hundreds of thousands, removes millions of kilograms of food for animals every year and returns nutrients to the soil in the form of millions of kilograms of animal waste. The value of common species is not just ecological and economic, but psychological. Study after study demonstrates that encounters with the natural world improve our mental state. Losing familiar species— whether birds in our backyard or butterflies on our doorstep—is likely to shrink(收缩) such opportunities for engagement. Rarity will always occupy a significant place in conservation. But in our pursuit of a sustainable and biodiverse future, we must avoid “the extinction of commonness”． 1．What is the purpose of the first paragraph？ A．To make a survey. B．To offer a suggestion. C．To introduce the topic. D．To provide an example. 2．What does the example of the bird study suggest according to the text？ A．Species loss balances the ecosystem. B．Birds return many nutrients to the soil. C．Species' rate of decline arouses people's concern. D．Birds are described as widespread and secure animals. 3．What can we conclude from the passage？ A．Rarity matters most in conservation. B．Familiar species shouldn't be ignored. C．Biodiversity results in the extinction of commonness. D．People's physical state shrinks for sustainable development. 4．Where is this text most probably taken from？ A．A news report. B．A health column. C．A biology magazine. D．A travel brochure. 三、应用文写作 假定你是学生会主席李华，为了提高大家保护濒危物种的意识，请你代表学生会撰写一篇关于保护濒危物种的倡议书。 ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 1 / 12 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $ UNIT 2 Wildlife Protection核心语法精练 （现在进行时的被动语态） 解析版 目录 1 二、考点夯基 4 一、单项选择 4 二、指出下列句中画线部分是什么句子成分 11 三、分析句子成分并写出基本句型 12 三、综合提升 14 一、语法填空（模考真题） 14 二、阅读理解（模考真题） 18 方式一：表格 现在进行时的被动语态基础梳理 类别 细分 构成/用法 单元主题例句 基础概念 核心含义 表示此刻/现阶段正在被进行的动作，主语是动作承受者 Wild animals are being hunted illegally.（野生动物正遭到非法捕猎） 主动对照 现在进行时主动：am/is/are + doing被动：am/is/are + being + 过去分词 People are protecting antelopes.（主动）Antelopes are being protected.（被动） 四种句式结构 肯定句 主语 + am/is/are + being + done The wetland reserve is being built now. 否定句 主语 + am/is/are + not + being + done Rare birds are not being well watched over. 一般疑问句 Am/Is/Are + 主语 + being + done Are the endangered species being saved? 特殊疑问句 疑问词 + Am/Is/Are + 主语 + being + done What measures are being taken to save wildlife? 高频考点规则 特殊规则 短语动词被动 look after/take care of/talk about 等短语被动，介词不能丢 The injured deer is being taken good care of. by短语省略 不强调动作执行者时，可省略by sb.

B．To offer a suggestion. C．To introduce the topic. D．To provide an example. 解析：C　推理判断题。根据第一段中的“These scarce(稀少的) plants and animals are extremely valuable; they represent the final hope for preventing extinction. The efforts toward conserving rare species have made an enormous difference.”可知，文章开头首先肯定了我们对稀有物种的保护和取得的成就，但最后一句“But the attention to rarity could come at the expense of overlooking the ordinary.”将话题由对稀有物种的保护转向对普通物种的忽视；再结合第二段中的“Increasingly, conservation is turning its sights in this direction—to safeguard what is common, not just what is rare.”可知，关注并保护普通物种是本文的主题，所以第一段的目的是引入话题。故选C。 2．What does the example of the bird study suggest according to the text？ A．Species loss balances the ecosystem. B．Birds return many nutrients to the soil. C．Species' rate of decline arouses people's concern. D．Birds are described as widespread and secure animals. 解析：C　推理判断题。根据第三段中的“There are good reasons to consider the common.”和第四段“These declines include species once considered widespread and secure, like...The shocking losses are a reminder that the mark of a species in trouble is not rarity, but the rate of decline.”可推知，对普通鸟类研究的这些例子表明这些物种的减少速度令人震惊，引起了人们的担忧。故选C。 3．What can we conclude from the passage？ A．Rarity matters most in conservation. B．Familiar species shouldn't be ignored. C．Biodiversity results in the extinction of commonness. D．People's physical state shrinks for sustainable development. 解析：B　推理判断题。根据第五段中的“Notably, the shifts in abundance of common species can translate into sizeable shifts in ecosystem functioning.”和第六段中的“The value of common species is not just ecological and economic, but psychological.”以及最后一段中的“we must avoid ‘the extinction of commonness’”可推知，普通物种有生态、经济和心理上的价值，不应该被忽视。故选B。 4．Where is this text most probably taken from？ A．A news report. B．A health column. C．A biology magazine. D．A travel brochure. 解析：C　文章出处题。通读全文，尤其是第二段“If we are to conserve nature, we must maintain our focus on the familiar. Increasingly, conservation is turning its sights in this direction—to safeguard what is common, not just what is rare.”和最后一段“Rarity will always occupy a significant place in conservation. But in our pursuit of a sustainable and biodiverse future, we must avoid ‘the extinction of commonness’．”可推知，本文论述在物种保护中保护普通物种的重要性，与生物学相关，所以最可能出自生物学杂志。故选C。 三、应用文写作 假定你是学生会主席李华，为了提高大家保护濒危物种的意识，请你代表学生会撰写一篇关于保护濒危物种的倡议书。 参考范文 It is well known that a great many human activities have caused a great threat to our home—Earth.
