[解析]
36.D.考查的是上下文的语境理解能力.从空后面But I can help you find more hours in your day for the things that really matter句意上可以看出这儿与前一句的转折之意,即我不能神奇地使你一天有25小时,故选D.
37.F.考查的是上下文的语境理解能力.从空前面看to exercise,to read that book you"ve been meaning to finish,正好与这儿的F项相连接,或只是为了让你的一天平静和有组织的开始,所以F项正确.
38.C.考查的是上下文的语境理解能力.此空出刚好需要一个对前面You can afford to spend at least an hour working on big,important tasks rather than on all those little urgent ones短意的小结,C项表示如果这样做下去的话,会达到节省时间的效果.所以C项正确.
39.A.考查的是上下文的语境理解能力.从空前面When you've got a big task to focus on,let your calls go to voicemail看是进行事例的说明,即如果你有办公室的门,关上它,选项中只有A项符合,故选A.
40.G.考查的是上下文的语境理解能力及主题句的概括能力.根据后文And if you're facing a difficult task,try breaking it into small steps or stages so that it's easier to deal with可知应该专注于你的工作.故选G.
