No storyline details are being shared, but CBS has revealed that Young Sheldon's Iain Armitage, Lance Barber and Montana Jordan will appear in an upcoming episode of mothership series The Big Bang Theory.
故事情节的细节尚未公布，但是CBS已经透露《小谢尔顿》里的三位演员伊恩·阿米蒂奇，兰斯·巴伯以及蒙塔纳·乔丹将会客串即将播出的《生活大爆炸》第12季。

Armitage's Sheldon, Barber's George and Jordan's Georgie will make cameos in an episode that will air in December as their Young Sheldon characters, according to CBS.
据CBS报道，阿米蒂奇饰演的谢耳朵、巴伯饰演的乔治以及乔丹饰演的Georgie将会客串一集12月播出的《小谢尔顿》。

Young Sheldon co-creator Steve Molaro, said “There's no reason why we can't keep going back and forth in this weird time portal that has been created between the two shows,” when it comes to the number of crossover episodes between CBS's Young Sheldon and its predecessor, The Big Bang Theory.
《小谢尔顿》的联合制片人史蒂文·莫拉说：”这两部剧集被创建在一个奇怪的时间门口中，我们没有理由不实现时空穿越联动，“这就涉及到在《小谢尔顿》和《生活大爆炸》中上演交叉剧集。

Because of the time difference between the two shows (they are set nearly three decades apart), tie-ins are difficult given the age differences.
由于这两部剧的时差(它们相隔近30年)，考虑到时间的差异，合作很难。

Young Sheldon and The Big Bang Theory are produced by Chuck Lorre Productions, Inc. in association with Warner Bros. Television.
《小谢耳顿》和《生活大爆炸》都是由Chuck Lorre 制作公司与华纳兄弟电视公司联合制作。

The Big Bang Theory airs Thursdays at 8 PM, followed by Young Sheldon at 8:30 PM on CBS.
《生活大爆炸》将于周四晚8点播出，小谢耳朵将于8点30分在CBS电视台播出。
