[解析]
(1)推理判断题。根据第一段中But looking back on that trip,what I remember most vividly is a New Year's Eve in Guatemala City,at a lifeless hotel.Rather than a countdown to midnight,I counted down the hours until my departure.( 但回顾那次旅行,我记得最清晰的却是在危地马拉城一家毫无生气的酒店里度过的新年前夜。我当时不是在倒数等待午夜的到来,而是在计算距离我离开还有几个小时。)"可知,作者不是在等着午夜倒计时,而是在数着还有几个小时能离开,而且那晚没什么特别的事发生,由此可以看出作者觉得那个新年前夜是很无聊的。故选A。
(2)推理判断题。根据第二段中The recency effect helps to account for our tendency to remember the ending part of a sequence of events with far more clarity than the rest,(近因效应有助于解释我们倾向于比记住其他部分更清晰地记住一系列事件结尾部分这一现象,)这句话说明近因效应有助于解释我们更容易清晰记住一系列事件结尾部分的这种倾向,也就是强调突出了一系列事件的最后部分。故选C。
(3)词义猜测题。根据第五段Keep in mind that the recency effect can also backfire.(要记住,近因效应也可能产生"backfire"。)接着举例Ending an amazing trip with stressful flight delays,lost luggage or feeling unwell might be enough to overshadow the entire experience,resulting in remembering the trip as awful instead of joyful(以紧张的航班延误、行李丢失或感觉不适来结束一次美妙的旅行,可能足以给整个经历蒙上阴影,导致你对旅行的记忆是糟糕的,而不是快乐的),这说明近因效应产生了不好的、不符合期望的后果,故划线词"backfire"在这里的意思是"产生不良后果",A.Be avoided to some extent.一定程度上要避免;B.Be applied extensively.应用广泛;C.Produce undesirable consequences.产生不良后果;D.Pose unexpected challenges.提出意想不到的挑战。故选C。
(4)推理判断题。根据最后一段中Then,as she is packing on the last day, "I go through all my little found treasures and spend a few moments recalling each one, " she said. "This gives me a sense of closure for that chapter of travel and makes the experience memorable. "(然后,在最后一天收拾行李的时候,她说:"我会浏览我所有的小宝贝,花点时间回忆每一件。""这给了我一种结束旅行的感觉,让我的经历变得难忘。")可知,Poffenroth认为故意收集旅行的纪念品,花时间浏览自己的旅游纪念品,能够让作者的经历变得难忘即可以帮助旅行者拥有良好的记忆。因此,D选项Purposely gather reminders of a journey.(故意收集旅行的纪念品。)有助于游客们拥有美好的旅游记忆。故选D。
