【1】staying 考查非谓语动词。从结构可知此处是非谓语做主语,用动名词形式,填staying。
【2】which考查关系代词。在非限制性定语从句中缺少主语,用关系代词which指代前句话内容。
【3】in 考查介词。固定短语:result in 导致,造成,填in。
【4】comfortable考查形容词。此处是和constant并列做temperatures的定语,故用形容词形式。
【5】are exposed考查谓语动词。Expose是及物动词,句中没有宾语,判断用被动形式,be exposed to “暴露在……之下”,根据主谓一致原则,填are exposed。
【6】a 考查冠词。固定短语:a significant amount of“大量的”,填a。
【7】compared考查非谓语动词。此处是“连词+分词”结构,compare和句子主语outdoor workers之间是被动关系,用过去分词,填compared。
【8】One考查数词。从上文内容可知此处指两组中的一组,因位于句首,故填One。
【9】lower考查比较级。根据句中than可知此处用比较级,修饰名词levels,用形容词,故填lower。
【10】possibly考查副词。修饰动词lose用副词形式,故填possibly。
