43、onderful food was his Christmas miracle.”也就是说好消息就是能得到美食，那小老鼠怎样才能得到美食呢？邻居家是不可能的，因为有猫。据此可判断，有一家人就要搬进农舍，会带来许多美食；此外，可添加细节，小老鼠的家人来陪他过圣诞节。2Paragraph 2：The house came alive the next few days.在接下来的几天里这所房子热闹起来。情节分析房子里面有人住了，和先前没有人住相比肯定是变得有生气了，结合文章可知小老鼠非常盼望有人来这农舍里住，现在它的愿望得以满足，所以一定非常享受这热闹时光。如果情节就这样发展，显得平淡，后续情节一

65、why teach a robot how to understand a video when it can easily follow a fixed program? Alimonies believes predetermined instructions lack flexibility.
