譯文

盡管人們對持續(xù)的壓力有害健康的觀點不加懷疑，卻有幾項研究表明，如果你能在富有挑戰(zhàn)性的境遇中隨機應(yīng)變，這種境遇將對你有好處。

點睛

本句的主干是studies suggest that。while引導(dǎo)的是讓步狀語從句，其中that引導(dǎo)的是主語從句；主句中that引導(dǎo)的是suggest的賓語從句，其中in which引導(dǎo)的in which you're able to rise to the occasion是situations的定語從句。

there's no question的意思是“毫無疑問”。如：

He's the best; there is no question about it. 他是最棒的，這毫無疑問。

rise to the occasion的意思是“善于處理突如其來的困難，隨機應(yīng)變”。

be good for的意思是“對……有益的，有幫助的”。如：

Regular exercises are good for your health. 堅持運動有益健康。
