考查固定搭配。Accordingtoresearch为固定搭配，意为“根据研究表明”。故选According。17.考查副词。Thus意为“因此，从而”，引导结果状语，对应句意“因此，那些长期睡眠不足的人往往难以集中注意力”。故选Thus。18.考查连词。Because引导原因状语从句，对应句意“因为睡眠不足的人更容易经历负面情绪”。故选Because。19.考查介词。Withoutadequaterest为介词短语，意为“没有充足的休息”，引导条件状语，对应句意“没有充足的休息，大脑就无法更好地调节压力荷尔蒙”。故选Without。20.考查连词。so...that...结构，so引导结果状语，that引导结果从句，意为“如此……以至于……”，连接前后两个分句，表达因果关系。故选so。21.考查虚拟语气。Itisimportant/necessary/essentialthat...结构，主语从句应用动词原形。原句should已包含在important中，应删除。故选ImportantthatyoufinishtheprojectbeforeFriday。22.考查同义转述。Thereason
