1、weakening of her eyesight with the setting in of winter
with是"随着..."伴随状语,setting的意思有"凝结; 凝固,硬化".因此,本句意思为"随着冬天的气温骤降,她的视力也衰退了."
(PS.这也与常识相符合啊,近视眼到了冬天更近视~)
2、light boxes can be programmed to correspond to shifts in the body clock
program作vt时,意思可以是"规划,拟...计划,安排...入节目"be programmed to是被动加目的.因此,"be programmed to correspond to shifts "是"设计它以适应变化(提高机动反应能力).
