【解析】
这是一篇说明文。一项研究表明空气污染会导致人的智力降低。文章用研究结果来证明该研究,并呼吁政府采取措施解决这一问题。
【1】考查介词。此处考查短语be responsible for“对……负责”,故填for。
【2】考查名词。此处应填intelligent的名词作为in的宾语,故填intelligence。
【3】考查名词的数。score“分数”是可数名词,结合语境判断此处用复数形式,故填scores。
【4】考查时态和语态。此处是句子谓语动词,由over four years ago判断为一般过去时,又主语the study和conduct之间是被动关系,故用一般过去时的被动语态,主语是单数,故填was conducted。
【5】考查非谓语动词。分析句子可知,此处是非谓语动词作后置定语,tests和take之间是逻辑上的被动关系,故用过去分词作后置定语,故填taken。
【6】考查副词。结合句意可知,此处意为“尤其”,其表达是particularly,故填particularly。
【7】考查定语从句。分析句子结构可知,此处是非限制性定语从句的关系词,先行词polluted air在从句中充当主语,故用关系代词which,故填which。
【8】考查形容词比较级。此处考查固定句型“the + 比较级, the + 比较级”越……;越……,故填longer。
【9】考查主谓一致。此处是句子谓语动词,本文讲述一般事实,故用一般现在时,主语shortcut是单数,故填is。
【10】考查非谓语动词。此处考查短语take measures to do sth.“采取措施做某事”,用不定式作目的状语,故填to reduce。
第7小题考查定语从句关系词。确定定语从句关系词一般分为三步:找出先行词;分析先行词在从句中充当什么成分;考虑特殊情况。以本题为例:
找出先行词:polluted air
分析先行词在从句中充当什么成分:polluted air在从句is the fourth biggest cause of global deaths.中充当主语,应用关系代词
考虑特殊情况:非限制性定语从句中不用that
故填which
