1
From VOA Learning English, this is the Health Report.
2
Many people say they cannot start their day without first having a cup of coffee or tea.
3
People say these drinks help them think clearly and feel awake.
4
This is because of caffeine, a substance found in some plants.
5
Caffeine helps to give a jump start to the nervous system.
6
Now, a report says it may also improve long-term memory.
7
The report was published in the journal Nature Neuroscience.
8
Mike Yassa is with the University of California in Irvine.
9
He and other researchers wanted to know if caffeine could improve what they called memory consolidation.
10
They asked a group of individuals to learn something new.
11
Then, the same people were given caffeine, the active ingredient in coffee, tea, and chocolate.
12
The research team studied 160 people who were caffeine-free.
13
On the first day, these people were shown pictures of everyday objects.
14
They were asked to identify whether the pictures could be found inside the house or outdoors.
15
Some people were then given a pill with caffeine.
16
The others were given a placebo, a pill containing an inactive substance.
17
On the second day, all of the subjects were asked to look at more pictures.
18
Some of the images were exactly like the ones they had seen 24 hours earlier.
19
but other images were different.
20
Individuals taking the caffeine pills had a 10 to 12 percent increase in their ability to remember objects.
21
The amount of caffeine used in the study was similar to a strong cup of coffee.
22
Mr. Yassa says pills with a little more caffeine also increased memory,
23
but resulted in some people appearing more nervous.

上下文与背景

本期健康报告来自美国之音学习英语节目，探讨了咖啡因对记忆力的影响。许多人开始一天的生活时，都会选择咖啡或茶，这些饮品不仅让人感到清醒，还可能改善长期记忆。研究由加州大学欧文分校的迈克·雅萨教授领导，旨在探索咖啡因如何帮助人们巩固记忆。此研究的重要发现已发表在《自然神经科学》期刊中。

日常交流的五个常用短语

  • “我需要一杯咖啡。” - 这是许多人早上的共同感受，表达了咖啡在日常生活中的重要性。
  • “咖啡因让我清醒。” - 强调了咖啡因对思维清晰和精力充沛的积极作用。
  • “这项研究表明…” - 用于引入某个研究或发现，为讨论提供依据。
  • “记忆巩固过程。” - 这是一个在心理学和神经科学中常见的术语，涉及信息的长久保存。
  • “我感觉更加紧张。” - 描述了一些人对咖啡因的负面反应，反映个体差异。

逐步跟读指南

在练习此视频中的发音时，您可以遵循以下步骤进行影子跟读，这不仅有助于提高英语发音，也能增强您的理解能力。

  1. 观看视频: 首先，观看完整视频，注意说话者的语调和音调。尤其是与记忆和咖啡因相关的段落，可以帮助您理解内容。
  2. 逐句重复: 选择一段较短的句子进行逐句重复，模仿说话者的语音。这是提高英语发音的有效方法。
  3. 分析发音: 专注于每个单词的发音，特别是“caffeine”等较难发音的单词。可以使您的英语口音更加自然。
  4. 结合关键词: 在跟读时，尝试使用文中提到的关键词，比如“咖啡因”和“记忆巩固”，将它们融入您的日常对话中。
  5. 反复练习: 多次重复和练习这些句子，直到您能够流利地说出这些句子并准确表达其含义。

通过这样的影子跟读练习，您的雅思口语练习能力和英语影子跟读技巧将会显著提高，为您的语言学习之旅增添动力。

什么是跟读法？

跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
