[解析]
(1)细节理解题。根据第一段From classic books like A Wrinkle in Time to classic movies like Back to the Future,children and adults both have been fascinated by the concept of time travel for hundreds of years.But is it even possible?(从《时间的皱纹》这样的经典书籍到《回到未来》这样的经典电影,数百年来,儿童和成人都对时间旅行的概念着迷。但这有可能吗?)可知,无论是书籍《时间的皱纹》,还是电影《回到未来》内容都是关系时间旅行的,这一类的书籍或者电影属于科幻类。即Back to the Future 属于科幻类电影,故选B。
(2)推理判断题。根据第二段Time travel sounds simple:you just move back and forth between different points in time like you would between different points in space.You could jump forward into the future,or you could jump back to sometime in the past.(时间旅行听起来很简单:你只是在不同的时间点之间来回移动,就像你在空间的不同点之间一样。你可以跳到未来,也可以跳回到过去。)可知,本段是对时间旅行这个概念的解释。故选C。
(3)推理判断题。根据四段Some scientists believe that parts of Albert Einstein's theories of special and general relativity might allow for the possibility of time travel.(一些科学家认为,阿尔伯特•爱因斯坦的狭义相对论和广义相对论的部分内容能够使时间旅行成为可能。)可知,阿尔伯特•爱因斯坦的狭义相对论和广义相对论为时间旅行提供了理论支持。故选C。
(4)推理判断题。根据最后一段It can be fun,though,to think about what problems might be presented by time travel.It may create an absurd(荒谬的)situation.(不过,思考时间旅行可能会带来哪些问题可能会很有趣。这可能会造成一种荒谬的情况。)Confusing as it sounds,we hope that any scientist who ever manages to make time travel possible works out these problems in advance.(尽管听起来令人困惑,但我们希望任何一位能够让时间旅行成为可能的科学家都能提前解决这些问题。)可知,时间旅行会带来一些使人们感到困扰的荒谬的事情,又根据作者列举的具体的例子let's say that you travel back in time to the day your parents met.What if your showing up on the day your parents met caused a ripple in time that led to them not meeting?If they had never met,you would never have been born.If you had never been born,how could you ever exist to travel back in time to cause the problem you just caused.(比方说,你回到了你父母相遇的那一天。如果你在你父母见面的那天出现导致他们没有见面的时间涟漪呢?如果他们从未见过面,你就永远不会出生。如果你从来没有出生过,你怎么可能存在到时光倒流而导致你刚刚造成的问题呢?)可推断出这种荒谬是一种自我矛盾的情况。故选D。
