字號:

Studies of both animals and humans have shown that sex hormones somehow affect the stress response, causing females under stress to produce more of the trigger chemicals than do males under the same conditions.
    【分析】多重復合句。主句主干為 Studies have shown that...。that 引導賓語從句,其主干為 sex hormones somehow affect the stress response。現(xiàn)在分詞結構 causing females...作結構狀語,為避免頭重腳輕,比較結構 more...than 引導的狀語從句用了倒裝語序,正常語序為:...than males under the same conditions do,其中 do 替代前面的 produce。
    【譯文】對動物和人類的研究表明:性激素會以某種方式影響對壓力的反應,使處于壓力下的雄性比處于相同條件下的雄性產(chǎn)生更多的觸發(fā)不良反應的化學物質。
