[解析]
(1)C.推理判断题。根据第一段We've all heard the stories of an actor's struggles before a career breakthrough:living a hard life,working part time,being a couch potato before getting that major role.Shelby,the star of"A Dog's Way Home,"has a hard﹣luck tale that could top them all.Before her big break,she was living in a landfill,rooting through garbage for her next meal.(我们都听过演员在事业上取得突破之前的挣扎故事:过着艰苦的生活,兼职工作,在得到那个主要角色之前成为一个电视迷。《一条狗的回家之路》中的明星谢尔比有一个倒霉的故事,可能会超过所有人。在她的重大突破之前,她住在垃圾堆里,翻着垃圾寻找下一顿饭。)由此可知,作者在一开始就提到了一个演员在事业取得突破之前的挣扎,并介绍了一只狗的类似但更引人注目的经历。故选C。
(2)D.细节理解题。根据第三段中One day,Miller spotted Baby Girl's adoption photo."Honestly,it was a really good picture,and she was flat﹣out smiling,"Miller said.Then she met Baby Girl,and assessed her on personality and the ability to respond to simple commands.(一天,米勒发现了Baby Girl的收养照片。米勒说:"说实话,这张照片拍得很好,她笑得很灿烂。"然后她遇到了Baby Girl,并对她的性格和对简单命令的反应能力进行了评估。)由此可知,她的性格和能力最终帮助Baby Girl在电影中获得了重要角色。故选D。
(3)B.句意猜测题。根据倒数第二段中Most of the film's reviews have praised Shelby's performance.Variety made the comments"an amazing dog,perfect performance!"(大多数影评都赞扬了谢尔比的表演。Variety评论道:"一只神奇的狗,完美的表演!")和最后一段Shelby has come a long way from the dump.But Buhler said she saw Shelby recently had needed only a second to compare the movie star with the dog she found from piles of trash."She's exactly the same,"(谢尔比从垃圾场一路走来。但布勒说,她最近看到谢尔比只用了一秒钟就把这位电影明星和她在垃圾堆里找到的那条狗做了比较。"她完全一样"。)由此可知,通过在最后一段中说她完全一样",布勒可能是指狗狗生活的巨大变化并没有改变她的内在品质。故选B。
(4)C.标题判断题。文章介绍了一只垃圾小狗到成为一名电影明星的引人注目的经历。所以C项From a Landfill Puppy toa Movie Star.(从垃圾小狗到电影明星)为最佳标题。故选C。
