In 2004, (he completed CIS tower became Europe’s largest （ ） of vertical solar panels. A vertical solar project on such a large （ ） has never been repeated since.

［E］空格前为副词first“最初”和系动词was,空格处可填入实义动词，构成被动语态。结合时间状语in 1962以 及后半句的内容：它的表面用方块石头覆盖（it was covered with thin square stones）,可知本句描述的是大厦刚建造时的样子。词库中constructed意为“建造”，与was构成被动语态，符合文意，故选E项。
［O］空格前为系动词was,until时间状语从句的主语是renovation“整修”，可知空格处应填入形容词构成系表结构或填入动词的过去分词构成被动语态。由于词库中的两个形容词cheaper“更便宜的”和cleaner “ 更干净的”与文意不符，故应填入动词的过去分词。结合下文内容：他们一致赞同用太阳能电池板对大厦进行全覆盖（They agreed to cover the entire building in solar panels）可知，此处说的是对大厦进行整修。词库中的过去分词undertaken “着手做”符合语义语法要求，故选O项。
［F］空格前后都为名词，由此可知句子缺少谓语，故空格处需填入动词，时态应为一般过去时。由关键词During this renovation和下一句的They agreed to cover...可推测，整修并安装太阳能电池板需要找相关公司商议或咨询，词库中consulted符合文意，故选F项。
［C］空格前为形容词最高级largest，空格后为介词of，因而空格处应填入名词。结合下一句的on such a large... has never been repeated since“再也没有出现过如此大的…”可知，本句讲的是CIS大度垂直太阳能电池板的数量之多。词库中的名词collection指a group of things “一堆,一群（东西）”, 填入后意为 “最大的垂直太阳能电池板集群”，符合文意。词库中range为强干扰项，a range of...修饰同属一大类但相互 不同的人/物，如：a range of services “一系列服务”、a wide range of facilities “各种各样的设施”，而a collection of通常指一组相似的物品c结合文中语境，墙上的太阳能电池板是同一类产品，故选C项。
［N］空格前为不定冠词a和形容词large，故空格处需填入名词；on such a large...作后置定语修饰vertical solar project，填入空格处的名词应能与介词on搭配。根据上文对这项工程的描述，楼外铺设太阳能电池板，工程巨大，scale符合语义，on such a large scale意为“如此大的规模”，故选N项。
［I］空格前后的was overtaken构成被动语态“被超越”，空格处可填入副词修饰动词，词库中的副词有eventually“最终”和 necessarily“必定地；必要地”。结合前半句 For a long time... it was the tallest building... 和句中表转折关系的连词but,可知CIS大厦最后被米尔班克大厦超越，eventually符合此处语义，故选I项。
［K］空格前为系动词aren’t，空格后为形容词cost-efficient “合算的”，因此空格处可填入副词修饰形容词cost- efficient o根据句意：对投资商来说，这种绿色建筑并不……合算，但确实能减少污染，空格处填入necessarily “必然地”符合语义，故选K项。
［L］空格前that指代pollution，此处比较了矿物燃料与绿色建筑产生的污染。by energy...指出污染的来源，结合介词短语through fossil fuels “通过矿物燃料”，可推知使用矿物燃料是为了生产能源，词库中的名词 production“生产，制造”可与energy搭配，意为“能源生产”，符合此处语义，故选L项。
［A］空格前为系动词get“变得”，空格处可填入形容词作表语，说明主语的性质或特征，词库中cheaper和 cleaner可备选。后半句see more skyscrapers covered in solar panels“看到将有更多摩天大楼装上太阳能电池板”，其前提是As solar panel get..“随着太阳能电池板变得 ”。由前一句中的aren’t cost-effi¬cient 可知，作者此处在谈论成本代价，而非太阳能是否“更清洁的”，故排除cleaner，选A项。
［J］空格前为a race of “关于……的竞赛”，空格处应填入名词：空格后的but rather表明前后是对比关系，后 面比较的是哪座高楼大厦采集的太阳能最多，由空格前面的关键词tallest可知，前面比较的是“高度”，故选height“高度”。
