24.C【解析】细节理解题。题干问的是，作者喜欢樱桃什么。根据第二段中Asforcherries(樱桃),theyaresodeliciouswhocares（至于樱桃，因为它们很好吃谁在乎呢）可知，作者在乎的是它的美味。故选C。
25.B【解析】细节理解题。根据第三段中的Ifyoulike,asqueezeoffreshlemonjuiceonthebananaswillpreventthemturningbrown.可知，往香蕉上滴新鲜的柠檬汁是为了防止香蕉变成褐色，故新鲜的柠檬汁是被用来保持香蕉的颜色的。故选B。
26.D【解析】词义猜测题。根据最后一段中theylovefeedingthefruitandfrozenbananasintothetopofthemachineandwatchingtheicecreamcomeoutbelow可知，孩子们喜欢把一些水果和冷冻的香蕉放入到这台机器的上部，然后看到冰激凌从下面出来。故可以推出ajuicer就是一台机器。故选D。
