[解析]
(1)B.逻辑衔接题。根据空格前一句While these are things that are out of our control,we can most certainly control how we react and feel in such situations.(虽然这些都是我们无法控制的事情,但我们可以很肯定地控制我们在这种情况下的反应和感受)可知,我们虽然有很多不能控制的事情,但是却能控制我们的反映和感受;再结合下文"Optimism is a simple yet powerful mindset that can affect us in many ways.(乐观是一种简单而有力的心态,可以在许多方面影响我们。)可知,空格处应该引入乐观这一主题。B项We can learn to keep optimistic(我们可以学习乐观)引出乐观这个主题。故选B.
(2)F.联系上文题。根据空格前When some people set a goal they don't account for the problems they run into.They view them as barriers that can't he removed.This is why the minute something doesn't go as planned they start to shrink and give up.(当一些人设定目标时,他们没有考虑他们遇到的问题。他们将其视为无法消除的障碍。这就是为什么一旦事情没有按计划进行,他们就会开始退缩和放弃。)可知,有些人在制定目标时没有考虑会存在的问题,所以会经常放弃。然后结合空格后In fact,an optimistic person will merely look at the problems as new experiences and new possibilities.(事实上,乐观的人只会把这些问题看成是新的经历 和新的可能性)可知,空格处应该陈述乐观主义者在遇到问题时该怎么办。F项On the other hand,an optimistic person is more open to problems(另一方面,乐观的人更容易面对问题。)陈述了乐观者面对问题的态度,承上启下。故选F.
(3)C.联系下文题。根据下文"A survey conducted by Gallup found that only 35 percent of US managers are occupied in their jobs.This lack of devotion and its influence on employees costs the US approximately 77 billion to 96 billion each year.Optimistic leaders can help motivate their employees.(盖洛普公司开展的一项调查发现,美国只有35%的经理在专心工作。这种缺乏奉献精神及其对员工的影响每年使美国损失约770亿至960亿美元。乐观的领导者可以帮助激励他们的员工。)可知,在公司中,如果领导是个乐观的人,公司的效益会很好。相反地,如果领导缺乏奉献精神那么会造成巨大的损失。由此推知,本段主要在讲述,在公司之中需要良好的氛围,这样可以带动大家。C项Optimists also spread a good atmosphere(乐观主义者也传播了一种良好的氛围)符合本段段意。故选C.
(4)G.联系上文题。根据空格前一句Optimistic leaders can help motivate their employees(乐观的领导者可以帮助激励他们的员工)可知,此处在陈述乐观的领导者会带动他的员工。由此推知,下文应该讲述乐观的人也会带动周围的人。G项Similarly,having a positive attitude can inspire everyone around us(同样,积极的态度可以激励我们周围的每一个人)承接上文。故选G.
(5)E.联系上文题。根据空格前一句"Pittsburgh concluded that those who have an optimistic viewpoint have a 30 percent lower risk of heart disease.(匹兹堡大学的一项研究得出结论,那些乐观的人患心脏病的风险降低了30%。)可知,乐观的人患心脏病的风险降低了30%,由此推知下文应该分析这一现象产生的原因。E项That's because they are generally happier and less stressed(这是因为他们通常更快乐,压力也更小)陈述了这个原因。故选E.
