D．They went to Globo TV for more information.

　　4．Who are Elton Plaster's biological parents?

　　A．The Aliprandis.

　　B．The Plasters.

　　C．Dimas and Elton.

　　D．Nilza and Adelson.

　　【解题导语】本文是一篇记叙文。两个名叫Dimas Aliprandi和Elton Plaster的同龄人由于出生时在医院被抱错，互换了父母和家庭，但这个错误反而促成了一个新的大家庭的诞生。

　　长难句分析：About a year ago, Aliprandi and the parents who raised him accepted an offer from the Plasters to move to their farm, where they built a home.(最后一段第一句)

　　分析：本句是复合句。who引导定语从句，指代先行词the parents；where引导非限制性定语从句，指代先行词"farm"。

　　译文：大约一年以前，Aliprandi和他的养父母接受了Plaster一家的提议，搬到了他们的农场，在那里他们组建了新家。

　　词汇积累：existence n．存在　switch v．调换，转变　eventually adv.终于，最终　biological adj.生物学的，有血亲关系的

　　1．B　细节理解题。根据第二段第一句"The chain of events started with Dimas...he grew up with."并联系下文内容可知，Dimas觉得自己和一同长大的四个姐妹长得不像，于是在长大后做了DNA鉴定，所以是他首先发现自己被抱错了。故选B。

　　2．D　细节理解题。根据最后一段第一句中的"About a year ago，Aliprandi and the parents who raised him accepted an offer from the Plasters to move to their farm"并结合下一句可知，Dimas Aliprandi和他的父母现在同Plaster一家住在一起；再联系倒数第二段第一句中的"where Plaster lived with his parents，Nilza and Adelson，in the town of Santa Maria de Jetiba"可知，Plaster一家住在Santa Maria de Jetiba；由此可知，Dimas Aliprandi和父母现在住在Santa Maria de Jetiba。故选D。

　　3．C　细节理解题。根据第三段最后一句"They at first refused to believe the results，but eventually decided to help him look for his biological parents."可知，Dimas的父母最初拒绝相信这样的结果，但是最后决定帮助他寻找亲生父母。故选C。

　　4．A　细节理解题。根据倒数第二段第二句"After tests，the Plasters discovered that Elton was the biological son of the man and woman that Dimas had been calling Mom and Dad for 24 years."可知，Elton Plaster的亲生父母是Dimas的养父母，即Aliprandi夫妇。故选A。
