試題分析：科學(xué)家發(fā)現(xiàn)呆在寒冷的環(huán)境下可以幫助人們減肥。因?yàn)樵诤�冷有助于棕色脂肪組織的形成，這種脂肪組織可以產(chǎn)生熱量，讓人們保暖。而棕色脂肪組織燃燒熱量，因此有助于人們體重的減輕。

【1】staying 考查非謂語(yǔ)動(dòng)詞。從結(jié)構(gòu)可知此處是非謂語(yǔ)做主語(yǔ)，用動(dòng)名詞形式，填staying。

【2】which考查關(guān)系代詞。在非限制性定語(yǔ)從句中缺少主語(yǔ)，用關(guān)系代詞which指代前句話(huà)內(nèi)容。

【3】in 考查介詞。固定短語(yǔ)：result in 導(dǎo)致，造成，填in。

【4】comfortable考查形容詞。此處是和constant并列做temperatures的定語(yǔ)，故用形容詞形式。

【5】are exposed考查謂語(yǔ)動(dòng)詞。Expose是及物動(dòng)詞，句中沒(méi)有賓語(yǔ)，判斷用被動(dòng)形式，be exposed to “暴露在……之下”，根據(jù)主謂一致原則，填are exposed。

【6】a 考查冠詞。固定短語(yǔ)：a significant amount of“大量的”，填a。

【7】compared考查非謂語(yǔ)動(dòng)詞。此處是“連詞+分詞”結(jié)構(gòu)，compare和句子主語(yǔ)outdoor workers之間是被動(dòng)關(guān)系，用過(guò)去分詞，填compared。

【8】One考查數(shù)詞。從上文內(nèi)容可知此處指兩組中的一組，因位于句首，故填One。

【9】lower考查比較級(jí)。根據(jù)句中than可知此處用比較級(jí)，修飾名詞levels，用形容詞，故填lower。

【10】possibly考查副詞。修飾動(dòng)詞lose用副詞形式，故填possibly。
