Research has proven that weather plays a part in our moods: Warmer temperatures and exposure to sunshine increase positive thinking, whereas cold, rainy days bring anxiety and fatigue. 26 , many people believe that bad weather can reduce productivity and efficiency.
答案：(D) Accordingly
前面講天氣影響情緒（暖天正面情緒、陰雨天焦慮疲勞），這句延續「因此」，許多人相信壞天氣會降低生產力，Accordingly（因此）承接這個邏輯推論；At most（至多）、In contrast（相反地，這裡是順接不是對比）、Literally（字面上地）都不合。
accordingly 長得太像 according to，你很可能直接把它讀成「根據……」。這兩個要分清楚：according to 是「根據」，後面一定要接名詞（according to the research 根據這項研究）；accordingly 是副詞，自己單獨站著，意思是「因此、於是」，和 therefore、thus 一樣屬於用來連接前後文的副詞（劍橋 English Grammar Today 把這類詞歸在「連接副詞」linking adjunct 底下），不能接名詞。
比對前後兩句的方向。前一句：研究證實天氣會影響情緒，暖天正向、陰雨天焦慮疲憊。這一句：許多人相信壞天氣會降低生產力。後者正是從前者推出來的想法，前因後果、同一個方向。驗算方式：換成 Therefore 或 Thus 讀一次，意思完全一樣，那就對了。
At most（至多、充其量）用在數量或程度的上限，像 It takes 20 minutes at most（最多二十分鐘）。In contrast（相反地）要求前後反向，但這裡是順著推下去，不是轉折——真正的轉折在下一句，由 however 帶出來，那才是全篇的轉彎處。Literally（字面上地、真的）與前後邏輯無關。105 年第 16 格也把 Accordingly 放進選項當誘答（該題答案是 However），可以兩題一起看：判斷方法都是先確定前後句同向還是反向，再從同向的一組（therefore、thus、accordingly）或反向的一組（however、in contrast、nevertheless）裡挑。
accordingly（因此、於是；也可表「照著、相應地」，如 act accordingly 照此行事）、according to（根據，後面接名詞）、therefore（因此）、thus（因此）、at most（至多、充其量）、in contrast（相反地）、literally（字面上地、真的）、play a part in（在……中起作用）。

There is, however, a significant 27 between such beliefs and the actual effect of weather on people's performance at work. Using empirical data from laboratory experiments 28 observations of a mid-sized Japanese bank in real life, researchers find that weather conditions indeed influence a worker's focus. When the weather is bad, individuals tend to focus more on their work rather than thinking about activities they could 29 outside of work. But photos showing outdoor activities, such as sailing on a sunny day or walking in the woods, can greatly distract workers and thus 30 their productivity.
The findings conclude that workers are actually most productive when the weather is lousy—and only if nothing reminds them of good weather.
