[解析]
(1)推理判断题。根据第一段Worry is defined as thoughts and images of a negative nature in which mental attempts are made to avoid the expected potential threats. (忧虑被定义为消极的想法和形象,在这种想法和形象中,人们在心理上试图避免预期的潜在威胁。)和第二段This means that most of the time we devote to worrying,which pushes us to try to come up with a solution to what is troubling us,is wasted,Thus,we not only caused ourselves unnecessary mental pain,but took up valuable minutes and hours that could've been spent elsewhere. (这意味着我们花在担忧上的大部分时间都被浪费了,这些时间促使我们努力想出解决困扰我们的问题的方法。因此,我们不仅给自己造成了不必要的精神痛苦,还占用了本可以花在其他地方的宝贵的分钟和小时。)可知,从前两段可以推知担忧浪费了本应花在解决问题上的时间。故选D。
(2)推理判断题。根据第三段To avoid this,it is often necessary to stay calm and trace the sources of worry.More importantly,we should analyze the situation and see whether it is the very problem that is bothering us.Blindly feeling nervous about whether the problem can be solved is sometimes nidicolous,for the problems do not exist.(为了避免这种情况,通常有必要保持冷静,寻找担忧的根源。更重要的是,我们应该分析形势,看看是不是问题本身在困扰我们。盲目地为问题能否解决而紧张有时是可笑的,因为问题并不存在。) 可知,第三段提到提到的管弦乐队的例子为了说明被想象的东西打扰是不明智的。故选C。
(3)推理判断题。根据最后一段The next time we find ourselves in the middle of worrying about some matters,we might be wise to stop and ask ourselves what the problem is and whether it will happen.Then we may be able to go on to do something more meaningful or at least avoid being disturbed by something imaginary. (下次当我们发现自己在为某些事情担心时,明智的做法是停下来问问自己问题是什么,它是否会发生。然后我们就可以继续做一些更有意义的事情,或者至少避免被一些想象的事情打扰。)可知,浪费在忧虑上的时间应该花在有意义的事情上。故选C。
(4)主旨大意题。根据最后一段The next time we find ourselves in the middle of worrying about some matters,we might be wise to stop and ask ourselves what the problem is and whether it will happen.Then we may be able to go on to do something more meaningful or at least avoid being disturbed by something imaginary. (下次当我们发现自己在为某 些事情担心时,明智的做法是停下来问问自己问题是什么,它是否会发生。然后我们就可以继续做一些更有意义的事情,或者至少避免被一些想象的事情打扰。)可知,本文主要讲述了如何处理忧虑。故选B。
