[解析]
(1)推理判断题。根据第三段When faced with new stimuli or experiences,we feel as if time is getting slower to allow more brain processing time.This contributes to why elder people often remark that time goes faster the more they age because being older often means fewer new experiences,so there is less need for the brain to interpret time more slowly to pay more attention to solving a problem.(当遇到新的刺激或经历时,我们会觉得时间变慢,因为大脑需要更多的处理时间。这也解释了为什么老年人经常说,年纪越大,时间过得越快,因为年纪越大,新的经历就越少,所以大脑不需要更多时间来解决问题。)由此可知,正是因为老年人没有机会遇到新的刺激或经历,所以他们觉得时间过得飞快。故选A。
(2)推理判断题。根据第四段In the case of the "return trip effect," after viewing the landmarks on the road while getting to the destination,it is easier to recognize these points on the way back.Having less sense of puzzle and being more certain of one's surroundings can make time feel faster.(在"回程效应"中,前往目的地时会看到途中的地标,这样返程的时候就会更容易认出这些标志。少了一些困惑,多了一些对周围环境的确定会让你感觉时间过得更快。接着作者指出许多活动也是这样,学会了过程就会觉得很自然,并以学骑自行车为例证明了这一观点。)由此可推知,学骑自行车的例子主要就是为了证明熟悉以后就会感觉很自然,就会感觉时间过得更快。故选B。
(3)细节理解题。根据最后一段This "return trip effect" is most notably noticed after reflecting on how long a trip to an unfamiliar location took.This explains why the "return trip effect" is usually associated with vacations and not daily commutes to work or school ("回程效应"在去往一个不熟悉的地方时表现得最为明显。这就解释了为什么"回程效应"通常与度假有关,而不是每天上班或上学。)即前往一个陌生的地方会使人感觉用时最长。故选B。
(4)标题归纳题。文章第一段就交代本文的主要内容:你以前可能有过这样的经历:感觉往返行程中的回程用时更短。这种现象的科学依据是什么?下文的Some theories和Another theory给出了可能的原因。可知,本文主要解释了为什么回程会使人感觉用时较少,D.Why does the "return trip effect" occur?(为什么会出现"回程效应"?)作标题最恰当。故选D。
