Most people cannot recall memories of being a baby, nor of their infancy. However, some people claim they can remember things that happened in the first year of their lives. Researchers at Yale and Columbia University in the United States studied why people have no recollection of things that happened in the first four or five years of their lives. The research team also investigated whether or not babies formed memories at all. Researcher Dr Tristan Yates suggested we may not be able to remember being a baby. He said: "Our results suggest that babies' brains have the capacity for forming memories, but how long-lasting these memories are is still an open question."
The research has been published in the journal "Science". It suggests that babies as young as a year old can form and store memories. Researchers used a specially designed scanner to observe activity in an area of babies' brains called the hippocampus. This is where memories are created and stored. The research found that babies can form limited types of memories from the age of two months. It is possible that infants can detect patterns in people's faces, language and in daily routines. However, episodic memory, which allows us to recall specific events, may take longer to form. The researchers say this kind of memory may not occur until the hippocampus has more fully matured.

Recall /rɪˈkɔːl/ - 回忆，记得
"Most people cannot recall memories of being a baby"（大多数人不能回忆起婴儿时期的记忆）。在这个句子中，"recall"指的是能够想起以前发生的事情。
Infancy /ˈɪn.fən.si/ - 婴儿期
"Most people cannot recall memories of being a baby, nor of their infancy."（大多数人不能回忆起婴儿时期的记忆）。"Infancy"表示生命的早期阶段。
Recollection /ˌrek.əˈlek.ʃən/ - 记忆
"However, some people claim they can remember things..."（然而，有些人声称他们能够记得一些事情）。"Recollection"指的是从过去的经验中回忆出的东西，常用于正式语境。
Hippocampus /ˌhɪpəˈkæmpəs/ - 海马体
"Researchers used a specially designed scanner to observe activity in an area of babies' brains called the hippocampus."（研究人员使用一种特别设计的扫描仪来观察婴儿大脑中名为海马体的区域的活动）。"Hippocampus"是大脑中与记忆形成和存储相关的区域。
Episodic memory - 情节记忆
"Episodic memory, which allows us to recall specific events, may take longer to form."（情节记忆让我们回忆具体事件，可能需要更长的时间来形成）。"Episodic memory"是一种能帮助我们记住特定事件和经历的记忆类型。
Claim /kleɪm/ - 声称，主张
"However, some people claim they can remember things..."（然而，有些人声称他们能够记得一些事情）。"Claim"是指某人表述某件事为事实，尽管不一定有证据支持。
Suggest /səˈdʒɛst/ - 建议，暗示
"Dr Tristan Yates suggested we may not be able to remember being a baby."（特里斯坦·耶茨博士建议我们可能无法记得自己是婴儿时的事情）。"Suggest"用于表达某种观点或理论。
Passive voice - 被动语态
"The research has been published in the journal 'Science'."（这项研究已在《科学》杂志上发表）。"Has been published"是被动语态，表示研究成果已被某杂志接受并发表。
Relative clauses - 定语从句
"The research team also investigated whether or not babies formed memories at all."（研究团队还调查了婴儿是否根本能形成记忆）。"Whether or not"引导了一个定语从句，进一步解释调查的内容。
Study - 研究
"Researchers at Yale and Columbia University in the United States studied why people have no recollection of things..."（美国耶鲁大学和哥伦比亚大学的研究人员研究了为什么人们无法回忆起事情）。"Study"是科研工作中常用的词汇，指的是对某一问题进行的系统性研究。
Results - 结果
"Our results suggest that babies' brains have the capacity for forming memories..."（我们的结果表明，婴儿的大脑有形成记忆的能力）。"Results"常用来指实验、研究或调查的结论。
First - 首先
文章开始时提到了很多人无法记得婴儿时期的记忆。使用"first"为文章引入了第一个话题，即人类对婴儿时期记忆的缺失。
However - 然而
"However, some people claim..."（然而，有些人声称...）。"However"是用来表示转折或与前述信息相对的内容，常用来引入不同的观点或反对意见。
In conclusion - 总结
虽然文章中没有使用这一短语，但你可以在阅读科研文章时，注意到最后对研究的总结性内容。科研论文通常会在最后用类似"To conclude"或"In conclusion"总结其研究发现。
Published in - 发表在
