【解析】本文是说明文。对许多成年人来说，很难回忆起儿时的一些经历。一项研究表明，我们的记忆力的变化与年龄有关。

51.考查动词。根据上文Most adults find it hard to remember the things happened while they were children. 大多数成年人发现很难记住他们小时候发生的事情。结合Now scientists have found exactly when these memories d___51___. 可知是现在科学家们已经找到了这些记忆消失的确切时间。“消失”disappear，由语境可知这里时态用一般过去时，故*填disappeared。

52.考查形容词。根据上文most three-year-old children can remember a lot of大多数三岁的孩子都能记住很多事情，结合首字母提示以及what happened to them a year e___52___,可知此处指的是一年前发生在他们身上的事，a year earlier“一年前”，故*填earlier。

53.考查副词。根据上文these memories are still clear while they are 5 and 6,这些记忆在他们5岁和6岁的时候仍然清晰，由转折词but，再结合首字母提示，可知此处句意为：但当他们超过7岁时，这些记忆会迅速减弱。“迅速地”rapidly，副词，修饰前面的动词，故*填rapidly。

54.考查名词。根据Most children by the age of 8 or 9 can only remember 35% of their e___54___

 from under the age of 3 according to the new studies. 结合语境及首字母提示：根据新的研究，大多数8岁或9岁的孩子仅仅能记住他们3岁以下35%的……。可知此处表达的是“经历、经验”，英文表达是experience，在这里用作不可数名词，故*填experience。

55.考查名词。根据They say that before the age of 7 children do not have a s___55___of time and place in their memories. 结合语境及首字母提示：他们说，7岁以前的孩子在记忆中没有时间和地点的……。可知此处表达的是“概念、观念”sense，前面有不定冠词a，所以用其单数形式，故*填sense。

56.考查动词。根据下文then forget them just several years later.几年后他们就会忘记，结合Children also have a far faster speed of f___56___ than adults.可知孩子 遗忘速度也比成年人快得多。“忘记”

forget，动词，of是介词后接动词的ing形式，故*填forgetting。

57.考查连词。根据上文children can often have clear memories of what they have done,以及then forget

them just several years later. 可知前后句之间是转折关系，结合首字母提示可知应用连词but，句意为：孩子们常常对他们所做的事情有清晰的记忆，但几年后就会忘记。故*填but。

58.（本题*不唯一，只要符合语境和题意即可。）考查动名词。根据上文 the first relaxing trip with

 your family, 以及下文and the first day of school.结合the first d___58___ accident you met, 可推知此处句意是第一次遇见……的意外，由首字母提示可知，*可以填“跳舞”dancing。（本题*不唯一，只要符合语境和题意即可。）

59.考查动词。根据前面的关键词return“返回”，以及后面的to discuss the same things“去讨论同样的事情”，可知这里表达的是“开会、聚集”，second session“再次聚集、开会”，句意为：然后，孩子们在5岁到9岁之间再次返回来讨论同样的问题。故*填session。

60.考查动词。根据The scientists found that between the ages of 5 and 7,the amount（量）of memories that the children could remember r ___60___ between 63%-72%.结合语境：科学家发现，5岁和7岁之间年龄段的孩子，能记住的记忆量……在63%-72%之间。可知此处表达的是“保持”remain，由主句中的found可知句子时态用一般过去时，所以这里应用remain的过去式remained，故*填remained。
