Answer 1

【答案】staying|which| in| comfortable| are exposed| a| compared| One| lower| possibly
【解析】(1)科学家发现寒冷的环境可帮助我们减肥。
(1)staying　考查非谓语动词作主语。句意：科学家们发现待在寒冷的环境中会有助于我们减肥。“__1__(stay)inthe cold”作主语，且表示抽象概念，故用动名词作主语。
(2)which　考查非限制性定语从句。句意：棕褐色脂肪燃烧热量，这可以帮助我们减肥。先行词为前面一句话，关系词在定语从句中作主语且表示“事”，故用which引导。
(3)in　考查动词短语。resultin“引起，导致”。
(4)comfortable　考查形容词。设空处后为名词，故可判断设空处应用形容词作temperatures的定语。
(5)are exposed　本题以定语从句的形式考查动词被动语态及主谓一致。设空处为定语从句的谓语动词，它需与先行词outdoorworkers(名词复数)保持一致；此外outdoor workers与expose“使暴露”为被动关系，故用被动语态。综上所述答案为areexposed。
(6)a　考查冠词。asignificant amount of为固定搭配，意为：大量的。anamount of后需加不可数名词。
(7)compared　考查非谓语动词作状语。comparedto为固定搭配，意为：与……相比。
(8) One　考查限定词。根据上句的“twodifferent control groups of mice”可判断此处答案为one。
(9)lower　考查形容词比较级。根据语境中的than可判断此处应为形容词的比较级。
(10)possibly　考查副词。设空处在句中作状语，故用副词形式。
