Answer 1

【答案】

【1】staying

【2】which

【3】in

【4】comfortable

【5】are exposed

【6】a

【7】compared

【8】One

【9】lower

【10】possibly

【解析】

试题分析：科学家发现处在冷的状态能帮助减肥。

【1】staying 考查非谓语动词。分析结构可知，此处是非谓语作主语，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。句意：白色脂肪储存能量，导致肥胖。result in导致，造成。故填in。

【4】comfortable 考查形容词。此处是和constant并列作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 “被暴露在……之下”，根据主谓一致原则，填are exposed。

【6】a 考查冠词。a significant amount of“大量的”。故填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。修饰动词用副词形式，故填possibly。
