More than half of former host cities for the Winter Olympics will be too hot 【1】 (deal) with such games by the end of this century. That is the 【2】 (predict) of a recent study.
It's not just the Olympics that are at risk now. 'The world of winter sports is changing as the global climate continues warming, ' says Daniel Scott, 【3】 climate-change researcher in Canada. He led a team of researchers, 【4】 used math to predict how winter conditions will have changed by February 2050 and 2080. February is the month when the Olympic winter games are 【5】 (typical) played.
Scott and his team forecast temperatures and snow cover for the 19 cities that have already hosted Winter Olympics, and two 【6】 (addition) cities: PyeongChang, South Korea,and Beijing, China, where the 2022 Winter Olympics will be held.
Scott's team 【7】 (begin) with looking at historic winter conditions, and then used computer models to predict conditions in the future. 【8】 (they) model predicted that by 2050, the average February temperatures in past Winter Olympic host cities will rise by 1.9 【9】 2.1 degrees Celsius.

【答案】
【1】to deal
【2】prediction
【3】a
【4】who
【5】typically
【6】additional
【7】began
【8】Their
【9】to
【10】increasing
【解析】
本文是一篇说明文。主要讲述一项研究预测,到本世纪末,一半以上的前冬奥会主办城市将会太热而无法举行这样的比赛。
【1】考查固定短语。此处考查短语too…to…“太……以至于不能……”,是固定短语,故填to deal。
【2】考查名词。根据the判断此处填predict的名词形式,故填prediction。
【3】考查冠词。结合上下文可知,此处意为“加拿大的一个气候改变研究者”,是泛指,应用不定冠词,又climate是辅音音素开头,故填a。
【4】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researchers在从句中充当主语,故用关系代词,故填who。
【5】考查副词。此处应填typical的副词修饰动词played,故填typically。
【6】考查形容词。此处应填addition的形容词修饰名词cities,故填additional。
【7】考查时态。此处是句子谓语动词,根据后文的used判断为一般过去时,故填began。
【8】考查代词。分析句子可知,形容词性物主代词修饰名词model,故填Their。
【9】考查介词。句意:过去主办奥运会的城市,2月平均气温增加1.9到2.1摄氏度。结合句意可知,此处应填意为“到”的介词,故填to。
【10】考查非谓语动词。分析句子结构可知,此处应填非谓语动词作状语,逻辑主语these temperatures和increase之间是主动关系,故用现在分词作状语,故填increasing。
第4小题考查定语从句。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。
找出先行词:researchers
分析先行词在从句中充当什么成分:先行词researchers在从句___4___ used math to predict how winter conditions中充当主语,应用关系代词who/that
考虑特殊情况:非限制性定语从句中不能使用that
故填who
